NOTICE.. ■» v Having the largest and best assorted Stock of Mathematical, Optical and ^ Philosophical Instruments, both of foreign and domestic manufacture, in the United States, we are enabled to offer unequalled facilities and inducements to intending purchasers. In ordering Instruments and materials from this Catalogue, it is merely necessary to state the edition and the numbers of the articles. All former Editions are superseded by this. All instruments and materials sold by us are warranted perfect for the purposes intended; and if not found so upon receipt, should be returned and exchanged for others. The prices throughout the Catalogue will be strictly adhered to. When no satisfactory Philadelphia or New York reference is given by the party ordering the goods, the money should accompany the order; but where it does not, (either from want of confidence or other cause,) the goods will be forwarded by express, with bill, C. 0. D., (collect on delivery,) provided a remittance equal to one-third the total amount of the order is sent with it. No order for a less amount than Twenty-Jive Dollars will be sent C'.O.D. The Express Company’s charge for collecting and returning the money on C. 0. D. bills, must be paid by the party ordering the goods. The safest and most economical method of remitting money is by Bank Draft or Post Office Order, made payable to us. Where neither of these can be procured, United States or National Bank Notes, or Postage Stamps, can be sent by express with safety, the sender prepaying the express charges. Goods ordered to be sent by mail must be prepaid, and the return postage included in the remittance. All packing boxes will be charged for, and all goods will be packed with the utmost care; but no responsibility will be assumed by us, for breakage or other damage, after a package leaves our premises, except upon special con¬ tract.

C0W5 Tf) i i&5 “^3 On retiring from the business which I established in 1853, and have been conducting at No. 924 Chestnut Street since that year, it gives me pleasure to recommend to my friends and former patrons, my successors, and solicit for them a continuance of the favors so freely bestowed upon myself. The present firm propose dividing their business into three departments, each partner giving one of those departments his special care and attention. Samuel L. Pox, my former partner, will devote himself to the Mathe¬ matical Department, which will comprise Drawing Instruments, of every description, Surveying Compasses, Engineer’s Transits and Levels, Surveying Chains, Tape Measures, Drawing Papers, and materials of all kinds used by engineers and draughtsmen Jesse S. Cheyney, formerly Principal of Friends’ Select School, in this city, will take the Department of Philosophy, which will comprise Magic Lanterns, Oxy-Calcium and Oxy-IIydrogen Stereoscopticons, with Pictures and Illustrations from all countries and upon all scientific subjects; Ther¬ mometers, Barometers, Globes, Air Pumps, Electric Machines, Magnetic Apparatus, &c., &c. William H. Walmsley, well known throughout the country as a Microscopist, and also a preparer of Microscopic Specimens, will take the Department of Optics, which will comprise Spectacles, Microscopes, Micro¬ scopic Objects and Accessories, Opera Glasses, Spy Glasses, Telescopes, ■Ophthalmoscopes, &c., &c. The new firm will continue to issue Priced and Illustrated Catalogues as follows:—Part 1st. Mathematics; Part 2d. Optics; Part 3d. Magic Lanterns and Stereopticons; Part 4th. Philosophical Instruments. Care will be taken in each department of the business that the instru¬ ments manufactured by the firm shall be well made, and accurate for the purposes intendedj and that all new instruments and improvements, of both European and American manufacture, shall be introduced with as little delay .as possible.

Although there are several makers of drawing instruments in Switzerland, yet there is but one manufacturer whose instruments uniformly come up to a standard of ab¬ solute perfection in quality of material and excellence of finish. The divider joints work regularly and smoothly, the points are carefully tempered and rounded, the pens dressed to draw a smooth line of any thickness in whatever position held. Other Swiss manufacturers imitate the form of these instruments, but cannot imi¬ tate their perfection in finish. 145. 143. 150. 151. 15 No. 145. Plain Dividers, 4.} inches long, each,. 146.

This square combines, in a most convenient form, five different instruments, viz., The Try-Square, the Miter, the T-Sqcare, the Graduated Rule, and (what is entirely new) the Centre-Square, for finding the centre of a circle. Fig. 1 explains its application as a Centre-Square. Put the instrument over the circle, as the end of the bolt or shaft, with the arms b a, a e resting against the cir¬ cumference, in which position one edge of the rule, a d, will cross the centre. Mark a straight lino in this posi¬ tion; apply the instrument again to another part of the circumference, and mark another line crossing the first. The point where the two lines cross each other will be the centre of the circle. The whole is the work of a mo¬ ment. Fig. 2 explains the application of the instrument as a carpenter’s Try-Square, n, and an Outside Square, l ; Fig. 3, as a Miter ; Fig. 4, as a T-Square and a Gradu¬ ated Rule ; Figs. 5 and 6 as an Outside Square for draw¬ ing, and a T-Square for machinists. The tongue D A, (Fig. 1,) being fastened, as it is, into the triangular frame b a e, cannot bo moved or knocked from its place,—in this respect constituting a great im¬ provement over the carpenter's Try-Square, T-Square, and Miter in common use. The instruments are made of the best material, neatly finished, and perfectly true. “ As a centre-square alone, it is invaluable to every mechanic. ... In short, it combines, in a most con¬ venient form, so many useful instruments, no mechanic’s list of tools can well be complete without a Universal Square .”—Scientific American, Sept. 22,1855. 515. 515.

Bergner’s Patent Section Liner, in morocco case, . . . $12 00 SAMPLES OF WORK DONE WITH RERGNER’S PATENT SECTION LINER. This Instrument is for indicating sections of objects in mechani¬ cal and architectural drawings, for drawing screw threads, lay¬ ing out the spaces for brick work, letterings on drawings, and all cases where narrow spaced parallel lines are need¬ ed. With it, a person of mod¬ erate ability or practice can produce an effect of uniformity and neatness, in sectional draw¬ ings, almost, or quite equal to the engine dividing of engrav¬ ings. The instrument consists 52 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. of a ruler, covered on the under side with india-rubber cloth, a triangle with a clamp¬ ing-screw, passing through near one of its edges, and a plate, with the necessary arrangement for producing a movement over equal spaces. The several parts are placed together as represented in the engraving, there being a little spring beneath the front edge of the top plate, which presses against one edge of the ruler while the triangle is clamped against the other edge. The ruler may be placed upon the paper in any desired position, the india-rubber cloth underneath keeping it there with per¬ fect security, and it thus acts as a guide for the triangle, which can be moved along over equal steps by alternately pressing down the ivory button and letting it spring back. This movement is produced by the action of a little pawl upon the ruler, which is always to be kept pretty sharp so that it will take a quick and certain hold. The length of the steps taken, or the distance between the lines drawn, is regulated by the screw above the spring, the distance moved over each time being greater as the spring is allowed to have more play. By changing the clamp.ng-screw on the triangle, any edge can be placed against the ruler. FASTENING TACKS AND HORN CENTRES. 690. 691. 694. 695. 700. 701. No. Prick. 690.

The Surveyor’s Transit, as above illustrated, has a Telescope, from ten to twelve inches long, constructed with the finest lenses ; under the telescope a level is attached for taking such levels as may occur in the practice of a surveyor. On one end of the axis of the telescope a divided circle, 4 \ inches diameter, is attached, for reading to min¬ utes angles of elevation and depression. The rim of the compass box is divided to J degrees, and is provided with a nonius for adding and subtracting the magnetic varia¬ tions of the needle. The limb on the divided circle outside the compass box, is pro¬ vided with two verniers at right angles to the telescope and read to minutes. The tripod head is arranged with shifting centre, for setting the instruments quickly over a given point without the trouble of altering the position of the legs. The tripod legs are made of very strong mahogany. V2 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. No - Price. 085.

ENGINEER'S TRANSIT. The description given on page 69 for the Surveyor’s Transit will apply for the En¬ gineer’s Transit, excepting that the latter has the axis or centre running from the lower parallel plate of the tripod head to the centre plate of the instruments, thus se¬ curing greater accuracy for laying of angles. The upper part of the Transit does not separate from the tripod head, as in the Surveying Transit, but is permanently at¬ tached to the parallel plates and leveling screws, and when put in its box, is unscrewed from the tripod at the lower parallel plate. 994.

It has a rack-and-pinion movement to both object and eye glasses, an adjustment for centering the eye-piece, and another for insuring the accurate projection of the object glass in a straight line. Both of these are completely concealed from obser¬ vation and disturbance by a thin ring, which slides over them. The Ys of this level are made large and strong, of the best bell-metal, and each have two nuts, both being adjustable with the ordinary steel pin. The level bar is made round, of well-hammered brass, and shaped so as to possess the greatest strength irt the parts most subject to sudden strains.

THE USE OF MATHEMATICAL INSTRUMENTS. hi the foregoing Catalogue we have divided the sets of Drawing Instruments into three classes, viz. : Brass, Fine German Silver, and Extra Fine Swiss. The brass in¬ struments are intended for schools; the fine German silver and the extra fine Swiss instruments for the practical draughtsman. Without the aid of some drawing instrument, a student cannot obtain a thorough knowledge of Geometry, Trigonometry or Surveying; but, a3 very few who go over these branches in youth ever make any practical use of them in after life, it is not neces¬ sary that the drawing instruments, which are furnished to schools, should be any finer in finish and quality than is sufficient fora clear demonstration of the problems. The sets of brass drawing instruments are equal to all the wants of a young student. But to the practical draughtsman, his drawing in-truments are next to his head and his hands, and they must be of the best material, well ami accurately finished. He uses them every day, and all day, and if they are not perfectly correct, the loss and delay occasioned by them, in one instance, will be much greater than the cost of a good set of instruments, which can be u-ed his lifetime. The fine German silver drawing instruments meet the wants of the practical man. The extra fine Swiss drawing instruments are more nicely finished than the fine Ger¬ man silver; the metal of which they are made resembles more closely pure silver; they are more substantial in their construction, and consequently more durable. As a gene¬ ral rule, draughtsmen give the preference to the extra fine Swiss drawing instruments. The fewest drawing instruments a mechanical or architectural draughtsman can pos¬ sibly perform his work with are the following, viz.:— A pair of Plain Dividers, 5 or 6 inches long, as No. 66. A pair of Dividers, 5 or 6 inches long, with changeable points, as No. 73. A pair of Small Spacing Dividers, as No. 78. A Spring Bow Pen, as No. 81. A Spring Bow Pencil, as No. 86. A Drawing Pen, as No. 87. A Drafting Scale. A T Square. A Triangle. A Drawing Board. An Irregular Curve. Half dozen Fastening Tacks. An engineer or surveyor can perform his work with fewer drawing instruments. The following list will suffice:— A pair of Plain Dividers, 5 or 6 inches long, as No. 66. A pair of Dividers. 5 or 6 inches long, with changeable points, as No. 73. A Drawing Pen, and a Drafting Scale. Tt must be borne in mind, that the above are lists of instruments which are absolutely necessary for the architect and the engineer to have, and without which he cannot follow his profession; but there are many other instruments mentioned in the Catalogue which can be added, and by their aid the work can be much simplified, and more speedily accomplished. Having made these general remarks we will now proceed to describe each of the drawing instruments—their use, and how to use them. JAMES W. QUEEN tc CO., PHILADELPHIA AND NEW YORK. 103 THE PLAIN DIVIDERS. to This instrument consists of two legs, the upper half of which are made of brass or German silver, and the lower half, or points, of tempered steel. In the fine instruments, the joints about vvhieh the legs move should be framed of the two different metals—German silver and steel ; by this arrangement the wear is much diminished, and greater uniformity and smoothness of motion is obtained. If this uniformity and smoothness be wanting, it is extremely difficult to set the legs quickly apart, at a desired distance; for being opened and closed by the fingers of one hand, if the joint is not good they will move by fits and starts, and either go beyond or stop short of the point; but when they move evenly the pressure can be so applied as to open the legs at once to the exact distance, and the joint must be sufficiently tight to hold them in this position, and not permit them to deviate from it, in consequence of a small amount of pressure which is inseperablc from their use. The joints of the dividers are tightened or loosened by inserting the two steel points of the key, into the two small holes on one side of the head of the dividers, and turning from one to tighten it, and in the opposite direction loosen it. THE HAIR-SPRING DIVIDERS. When greater accuracy in setting the legs apart is required, than can be obtained by the joint alone, a draughtsman uses the Hair-spring Dividers. The peculiarity of these dividers is, that the upper part of one. of the steel points is formed into a bent spring, which being fastened into the German silver portion of the leg, near the joint of the dividers, is made to fit into a groove, cut the whole length of the German silver part of the leg, into which groove this spring can be drawn, or let slip out, by turning the screw on the middle of that side of the dividers. No. 69 represents the Hair-spring Dividers when shut up; No. 69a represents the same dividers with the spring let a little out of the groove, by loosening the screw. To take a distance with the Hair-spring Dividers they must be opened as nearly as possible to the required distance; set the leg without spring on the point from which the distance is to be taken, and make the point of the other leg coincide accurately with the end of the required distance, by loosening or tightening the screw on the side of the spring leg. THE STEEL SPRING SPACING DIVIDERS. In mechanical and architectural drawings, it frequently occurs that a large number of very small equal distances are to be set off, not only at one time, but repeat¬ edly, upon the same drawing; for this purpose the ordinary dividers are too large and inconvenient to handle rapidly, and having nothing but the joint to hold them in their position, are liable to get their extension altered. For such work there is used a pair of very delicate dividers, made altogether of steel, the two legs of which are united at the top by an arched spring, and drawn together or opened by the screw in the middle. On the top of the arched spring an ivory or German silver handle is attached, by which the instrument can be quickly turned over and over, when used in spacing off a number of equal distances. The size of the spacing dividers mostly used are three inches long, with the legs delicately rounded from the regulating screw to the points. The advantages gained by these spacing dividers are, greater nicety and accuracy of adjustment, and no liability of accidental change when once adjusted. DIVIDERS WITH CHANGEABLE POINTS. If an arc or circle is to be described faintly, merely as a guide for the termination of other lines, the steel points are generally sufficient for the purpose ; but when arcs and circles are to be drawn permanently, and to show clearly, one point of the dividers must carry either a lead pencil or ink. To accomplish this the steel parts of the legs of the dividers are made so that they can be taken out and replaced by pieces, either for pencil or ink ; the small screws in the middle of the legs retain the points firmly in their places The cut 152 illustrates a set with a pen-point, a, a pencil-point, b, a dotting-point, c, a needle-point, d, and a lengthening-bar, e. 104 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. off when the rusting. d e pen- 0 01 1 1 1 i i V Tbe pen-point, a, consists of two steel blades, so bent that when the points nearly touch each other there is space above for holding ink ; the two blades arc drawn together or put apart by a regulating screw in the middle. One of ihe si eel blades works upon a joint at its upper end, so that the ink can be thoroughly cleaned point is to be put away, and thereby preventing its being injured by To use the pen-point, after securing it tightly in the proper side of the dividers, the ink is put in between the blades by a common writing pen, which should be drawn down and out between the points, then the points of the blades are brought to the proper distance apart for making the line—the closer the points are together the finer the line; the point of the pen must always be as near at right angles to the paper as possible ; a joint is made in the German silver part of the point, to re¬ gulate the proper inclination The pencil-point, b, is made of German silver, the lower part of which is formed into a tube; a lead-pencil is placed in this tube, and held tightly by the clamp-screw on the side. The dotting-point, c, is exactly like the pen-point, with the addition of a small toothed wheel, which revolves between the points of the blades, each tooth leaving a dot wherever it touches the paper; and thus, instead of a continuous ink line, a line of dots is made ; such lines are meant to illustrate the course of an imaginary line or arc. The needle-point, d , is made similar to the pencil-point; the tube on the lower end is only large enough to take a fine needle, which is held securely in its place by the thumb screw on the side. The needle-point is put in place of one of the steel legs of the di¬ viders, when a number of arcs are to be made from the same centre; it does not deface the drawing by large holes, as the ordinary steel points would. The pen, pencil, dotting and needle-points are all made with a joint near their upper end, in order to bring the points at right angles with the paper. The lengthening-bar, e, is made wholly of German silver, one end of which fits in place of one of the steel legs of the dividers, and the other end has a socket and binding- screw, for receiving and holding the pen, pencil, or dotting-point. It is used when larger circles or arcs are to be drawn than can be made by simply extending the legs of the dividers. The side of the dividers into which the needle-point fits, also the steel point, and the needle-point, are marked on the inside with small dots, to indicate where these points are to be put, when used; those points which are not marked thus, are to be used on the other side of the dividers. In a large drawing there is always a great amount of finer detail, which can be executed with more accuracy and ease by a set of small instruments. The cut, No 72, illustrates a set one-half the size of No 73, but constructed and used in the same manner. It is not provided with the dotting-pen and lengihening-bar. Above the joints of the dividers a handle is attached, by which it can be held and used with more facility than by taking.them by the joints, as is done with the large set. No 158 represents a set of instruments similar to No. 72, but has a spring over the joints, and a regulating screw in the middie of the legs, by which the points can be opened or drawn together with great nicety and exactness. The handle is of ivory and much longer than that of No. 72. With No. 158 there are two pen-points ; when they are both substituted in place of the steel points, an instrument for drawing parallel lines is obtained ; or, in other words, a railroad drawing-pen, the use of which see cut No. 92, page 10. POCKET DIVIDERS. It is oftentimes found convenient by the engineer and surveyor to have a pair of di- , _ _ _ ___,,-■ viders for use in the field, which can be carried with safety in the pocket; these are called pocket dividers ; the simplest form is a pair of ordinary plain dividers, 5 or 6 inches long, having a German silver sheath, with a blunt point, which screws over the steel points. No. 74 represents this form. JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YOItK. 105 Another form and pencil, and of the pocket dividers is so constructed as to include points for pet yet, all contained in a very small compass. No. 79 represents this form. The legs of these dividers are jointed together same as the ordinary plain dividers, but each of them is agam jou.tsd about the middle, so that the etuis can be folded in towards the upper joint; a deep slot is made in each leg; from their ends, anti running almost up to the middle joints in these slots, the steel points are neatly adjusted on pivots; the opposite end of one steel point is finished into a drawing-pen, anti the opposite end of the other into a tube for holding the lead-pencil; thus, when the steel points are revolved, either a pencil or pen-point is presented. When not in use, the legs are folded in at the middle joint; the inner sides of the legs of the dividers are filed out to receive the points, so that when they are not in use every delicate part is protected from injur}'. It will be readily seen, that with the legs of the dividers lully extended, and both of the sharp steel points presented to the paper, that we have an ordinary pair of dividers; by revolving the point which has the drawing-pen on the opposite end we will then have a pair of dividers with pen-point for describing ink circles; but if we should revolve the othef steel point, we should then have a pair of dividers with pencil-point for describing arcs and circles with the lead pencil. Fig. a represents No- 79 drawn on a larger scale, and folded for the pocket Another form of pocket dividers is represented by No 179. The legs aie jointed to¬ gether the same as an ordinary pair of dividers, but instead of being solid tbey are drilled out from the end almost up to the joint. The steel points, instead of having the pen and pencil-points at their opposite ends, as in No. 79, are jointed in the middle. When not in use the pen and pencil points are slipped into the holes in the legs of the dividers, and he steel point bent up against the inside, as repre¬ sented in the cut. W T iien a pair of plain dividers is wanted, the steel points are turned out straight with the legs of the dividers. When a pair of dividers with pen-point is wanted, the pen is withdrawn from the dividers and the steel point slipped into the hole in the leg ; and in the same way the pencil-point takes the place of us steel point, when a lead-pencil circle is to be drawn. For making very small circles, either of ink or lead-pencil, the points can be withdrawn from the legs of the dividers, and used inde¬ pendent. of ihcin. as the steel point, with pen-point, of itself is a bow pen, and the steel point, with lead-pencil holder, is a bow pencil. THREE-LEGGED DIVIDERS. Or, Triangular Compasses, are used for transferring triangular areas from one drawing to another It is an ordinary pair of plain dividers, with a third leg attached by a universal joint to the face of their joint, so that whatever may happen to be the form of the triangle the legs can be turned to bring each of the points upon one of the angles. To use the triangular dividers, open the main legs to take m the base then open and turn the third leg and bring it upon the angle above the base; the legs of the dividers are now set to the form of the triangle, which can be transferred correctly to any other drawing. BISECTING DIVIDERS. Or, Wholes and Halves, is a pair of ordinary dividers, with the legs continued beyond the joint; the legs, above the joint, being made exactly one-half the length of those below, therefore, when the longer legs are extended to any two points, the dis¬ tance between the points of the shorter legs will be one-half of that between the longer points. This instrument is very useful when a drawing 13 to be reduced one- 106 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK.

QUEEN & CO., PHILADELPHIA AND NEW YORK. 107 o o edge of a wooden ruler, at the distance apart of the radius of”the circle to be described; with one point upon the required centre, the other point is swung around, and the arc or circle completed. Under the whole length of one of the clamps a screw with fine thread and milled head is attached; upon this screw the point is adjusted; by turning the milled head, the point can be made to traverse from one side of the clamp to the other. The object of thi 3 screw is, after having adjusted the clamp on the ruler as near as possible, to enable the draughts¬ man to bring the points very accurately to the required distance apart by turning it one way or the other. No. T70 represents the other form of the beam compass, in which Ihe bar or rod is of German silver, about one-fourth of an inch in diameter, and divided into two or more sections, with screw joints, for the purpose of convenience in packing away when not in use. The points are attached to German silver tubes, which slide along the rod. One of the tubes can be adjusted to any position on the rod; but the other is fixed at one end, and can only be moved by the adjusting screw to regulate small distances. To prevent the tubes carrying the points from turning on the bar, a groove is cut the whole length of the bar, in which run steel guides pro¬ jecting from the inside of the tube. When the bars are screwed together, care must be taken to have the groove in each section brought to its right position to make the cut With these beam compasses there are two points, a needle, pen and pencil points; the fits in place of the round steel point, which is the stationary tube, and the pen and pencil place of the steel point attached to the mova- continuous. round steel needle point attached to points fit ble tube. in THE BOW PEN AND BOW PENCIL. These instruments are indispensable to an architectural or mechanical draughtsman, for describing small circles from one-sixteenth of an inch to two inches in diameter, * suc h as the heads of screws, the hubs and tires of wheels, There are two kinds of bow pens and bow pencils. Those represented by Nos. 84 and 85 arc about three inches long, and the leo-s are extended and closed by the pressure of the fingers; the joint upon which the legs move is the same as in the ordinary plain dividers; one of the legs is made with a permanent needle point the other leg is a pen or pencil point; both legs are jointed in the middle, so that the points can always be set at right angles to the paper. . t . The other and best form of bow pen and bow pencil is that with spring and adjusting screw. Of these there are two kinds. Those represented at Nos. 81 and 86 are made wholly of steel, except the handle, which is either of Ivory or German silver. The legs are made of one straight piece ot steel, which is bent in the middle until the two points come within one inch of each other, and then highly tempered. A steel wire, three-fourths of an inch long, having a fine thread cut on it, is fastened^ to the middle of one leg, and passes through the other ; a small German silver nut is screwed on the end ot this wire, and pressing against the leg, forces the points closer together; the parts of the legs above the screw being of tempered steel, when the nut is loosened, the points will move back with it. The other form of the spring bow pen and bow pencil is repre¬ sented by Nos. 82 and 83. The leg, body and handle are made of one piece of German silver or brass, three inches long; the 108 JAMES W.

Every draughtsman should provide himself with a fine oil stone for dressing the points of his dividers and pens, so as to keep them always in perfect working order; lie should also have a fine piece of buckskin, for wiping the instruments off before re¬ turning them to the case. In handling and using the instruments, the steel parts should come in contact with the fingers as little as possible, as the perspiration rusts the steel, but does not materially injure the brass or German silver. THE PROTRACTOR Is used for plotting surveys and laying off angles in general. Nos. 301 and 306 re¬ present semicircular pieces of horn, brass or german silver, on the middle of the diameter of which a dot or small cut is made, indicating the centre; the edges are divided into 180 parts or degrees, or 300 parts or half degrees; the best protractors are always divided in half degrees. The horn protrac¬ tors are made of a solid piece of horn, rolled as thin as writing paper; they are transparent, and the lines for each ten degrees are drawn almost from the centre to the edge (see No. 301). To reduce the weight of metal pro¬ tractors, and render them more convenient to use, a semicircular piece is cut out, leaving all round an edge one-half to three-quarters of an inch across; the circular edge is then divided in degrees or half degrees (see No. 306). To protract a survey, draw a north and south line, and take a point about the middle: bring the centre of the protractor over this point, and make the straight edge come even with the line; now set off the bearings on one side of the line for eastings, and on the other for westings; then remove the protractor, and draw faint lines from the centre to the points marked off, and with the parallel ruler, dividers and scale, bring the lines to connect, and form a figure of the survey. To set off an angle from a given point on a given line, bring the centre of the protractor to the point, and make the edge come on the line; then with the point of the dividers mark on the paper where the required degree comes, and draw a line from the given point to that point, and the angle made by the two lines will contain the required number of degrees. There is always more or less difficulty in marking off the degrees from the protractor, with the point of the dividers, to do it accurately and distinctly, so that when the pro¬ tractor is removed, the direction of the required line can be readily seen. To obviate this difficulty, the protractor with arm is made; the arm is simply a ruler of the same material as the protractor, jointed to the centre, so that it can be revolved from one side to the other; it projects about three inches beyond the edge of the protractor. After sitting the protractor on the line with its centre over the point from which the line is to start, bring the beveled edge of the arm to the required degree, and with the point of the pencil resting against that edge, draw a straight line; now, when the protractor is removed, there is no doubt about the position and direction of the line. The protractor with arm is divided in half degrees, and with it angles can be laid off correctly to fifteen minutes, but when great accuracy is to be observed, and the angles are required to be laid off to the very minute, a vernier must be attached to the arm. It is made by widening the arm, and cutting a square opening in it at the part where it crosses the edge of the protractor; the edge of the opening which meets the graduated edge of the protractor, is divided in such a manner as to enable the parts of a degree less than thirty minutes to be accounted for correctly, when laying off the angle. For a general description of verniers, see Gillespie’s Land Survey, Chapter II., page 228. 110 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. A whole circle protractor is made and used the same as the half circle ; it is, in reality two half circle protractors, having the same diameter. The bevel protractor is made of steel; it is half circle and with arm ; its straight edge projects beyond the arc both ways. The arm, instead of being fastened permanently at the centre, as is the case in other protractors with arms, has a narrow opening cut in it, almost from one end to the other; the arrangements which hold the arm to the protractor fit in this cut, and a clamp nut retains it in its place by loosening the clamp nut the arm can be slipped so as to project above the arc, or be¬ low the siraigbt edge, as may be wanted. This protractor is intended for the use of machinists, in obtaining or laying off bevels upon a niece of machinery. RECTANGULAR PROTRACTOR. This form of protractor is generally made of ivory, and six inches long, by one and three-quarters to two and a half inches wide; three edges of one side are divided in parts corresponding to the degrees and half degrees of the semi-circular protractor, the other edge has a divi¬ sion half way between the ends which represents the centre of the circle and the point in which the lines around the three edges would all meet, if continued. To understand the graduations around the edges, take a half circle protractor and bring its centre to the mark on the side not graduated, and make its straight edge correspond with that side ; now, it will be found that where the graduations on the edges of the two protractors come in contact they represent exactly the same number of degrees ; and if the other lines on the rectangular protractor were continued they would meet the corresponding ones on the semi-circular protractor. This protractor is used for the same purposes and in the same manner as the semi-circular protractor. Besides the protracting scale around the edges, one side of the rectangular protractor has on it a diagonal scale of equal parts, and scales of 20, 25, 30, 35, 40, 45, 50 and 60 equal parts to the inch ; also, a scale of chords for arcs of a circle four inches diameter • on the other side are scales of | in., £, f, £, f, £, f, 1, l£, l£ in., each subdivided into twelve parts; also, a scale of chords for arcs of a circle six inches diameter; the edge which has the centre mark on it is divided into forty parts to the inch. The diagonal scale consists of a series of eleven parallel and equi-uistant straight lines ; across these, and at right angles to them, another series of lines are drawn, having the spaces between every two lines to measure exactly one-quarter of an Inch. The top and bottom line of the eleven parallel lines have the first quarter of an inch divided into ten equal parts, also, the last half of an inch. A line is drawn from the first of these small sub-divisions of the first parallel line diagonally across the other nine lines, to the be¬ ginning of the sub-divided part of the lower line; and from each of the other sub¬ divisions of the upper line, lines are drawn parallel to the first diagonal line. It is readily seen, that at the point Where one of these diagonal lines crosses each one of the nine parallel lines, it increases its distance from the perpendicular line by one-tenth of one of the small sub-divisions for every parallel line. To take off distances of two figures, say 46,—chains, feet or miles,—place one point of the dividers at the fourth perpendicular line on the top parallel line, and open the dividers to the sixth sub-division at the beginning of the line. If we have three places of figures to take off, say 467,—chains, feet or miles,—open the dividers as before, along the top line, from the fourth perpendicular line to the sixth sub-division ; now bring the point of the dividers down the fourth perpendicular line to the seventh parallel line, the other point of the dividers then will not be on the intersection of the sixth diagonal line and the seventh parallel line; but when it is opened to that point the dividers will take in the required distance, viz., 467 General Rule. —To take off any number to three places of figures from a diagonal scale : on the parellel line, indicated by the third figure, measure from the diagonal line, indicated by the second figure, to the perpendicular line, indicated by the first figure. JAMES W. QUEEN 4 CO., PHILADELPHIA AND NEW YORK. Ill ENGINEER’S CHAIN SCALES, OF EQUAL PARTS, Are those which have one inch, or a portion of an inch, divided into a number of equal parts; they are marked 20, 25, 30, 35. 4 ), &c., &c.; and it is to be understood that each one of the fine divisions at the beginning of the lines is that part of an inch represented by the figures before the line ; that is, if 20, each one is the of an inch, and if 40, each division is the ^ s of an inch. There are but ten of the finer divisions marked off at the beginning of each line, after that, each graduation represents ten of the very 6mall ones. On the ivory protractors, and the scales usually with sets of instruments, it will be found that there is another set of divisions over the fine ones, on each line; these divide the first large space into twelve equal parts. The measuring chains used by engineers are fifty or one hundred feet long, and each link one foot long; therefore, if each one of the largo divisions on the scales is called a chain, the fine divisions will each represent ten links, if the chain used be one hundred feet long, and five links, if a fifty foot chain is used. The size of the drawing is there¬ fore regulated by the selection of one of these scales to lay off the length of the lines by. If the measures are in feet and tenths of a foot, each of the large divisions can be called one foot, and each of the fine divisions will be one-tenth of a foot. If the measure is in feet and inches, each one of the large divisions can be called one foot, and each one of the twelve fine divisions above the other fine divisions, will be one inch. ARCHITECT’S SCALES, OF EQUAL PARTS. In making a plan of a building or a drawing of a piece of machinery, it is necessary to make a small fraction of a foot represent a line, which, in reality, measures a whole foot; the scales mostly used for this purpose are T ' 6 of an inch, 5 3 2 , £, J, f, £, f, f, 1, 1J, and 3 inches to the foot; that is, every lGth of an inch is laid off the whole length of the scale, to represent feet, and the first 16ih is divided into twelve equal parts, to repre¬ sent the inches; and the same with the 3 3 2 , and all the other divisions to 3 inches to the foot. SCALE OF CHORUS. The chord of an arc is a straight line joining the two extremities of the arc. The graduations on the scale of chords represents the length of the chords of all arcs, from one degree to ninety degrees. The chord of an arc of sixty degrees is always equal to the radius or half the diameter of the circle. The chord of sixty is always used for describing arcs for laying off angles, or measuring angles already laid off. On some of the ivory scales there are found a number of other graduations, marked Rhu., Lon., Sin., Tan., S. T., Lat. These initials stand for Rhumbs, Longitudes, Sines, Tangents, Semi-Tangents, and Latitudes. As these are only used in the study and appli¬ cation of navigation we will omit describing them here, and refer those who wish to know their application to Heather’s Treatise on Mathematical Instruments, page 16. The scales described in the preceding pages are those usually found on the six inch ivory protractors, and six inch ivory scales. As a general rule, draughtsmen would prefer scales of greater length than six inches, and with only a certain class of divisions on them. The Ivory Chain Scale is twelve inches long, and has two edges bevelled, and graduated either to 10 and 10 part3 to the inch, or 10 and 20, and so on up to 100 parts to the inch ; the fine graduations being continued the whole length of scale. The Triangular Chain Scale is made of well-seasoned boxwood; the six edges are graduated each with a single scale, viz : one edge has 10 parts to the inch, one 20 parts, one 30*parts, one 40 parts, one 50 parts, and one 60 parts. The Triangular Scale for architects has five edges, graduated with two scales on each edge, as follows: one edge has each of an inch, and each of an inch marked off; the are numbered from one end aud the fa from the other. One edge has each £ of an inch, and each } of an inch ; one edge has each $ of an inch, and each £ of an inch ; one edge has each $ of an inch, and each an inch ; one edge has every 1.} inches, and every 3 inches; and one edge is divided into inches and 16ths of an inch. The first division of the scale is divided into four equal parts; consequently, if the represent one foot, each of the sub-divisions will represent 3 inches. The -f s , J, J, and §, have the first division 112 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. (hrVlrd into twelve equal parts; therefore, if the primary division represent one foot, ewh of the sub-divisions will represent one inch. The } and f of an inch have the first division divided into twenty-four equal parts; therefore, if the primary divisions repre¬ sent one foot, each of the sub-divisions will represent the half of an inch. The 1 inch and 1£ inches have the first division divided into forty-eight eqml parts; and if the primaly division represent one foot, each of the sub-divisions will stand for one-quarter of an inch, llie 3 inches has the first division divided into ninety six equal parts; and if the primary division represent one foot, each of the sub-divisious will represent the one-eighth of an inch. Tlie Ivory and Boxwood Flat Architect’s Scales, Nos. 406 and 454, are 12 inches long by 1 1 inches wide, and have the following divisions o‘< them, viz.: 4 J», 1 s i s 3 ■g, 1, 1 2 , 1J 3, 2|-, 2J, 2f, and 3 inches to the foot; the and 1 inch divisions are graduated on the two edges of one side; all the other divisions are laid off on the body of the scale. The primary division of each scale is divided into twelve equal parts, to represent inches; and in the f, f, f, |, 1}, lj, if, 2, 2$, 2’-, 2}, and 3 inch scales, the primary divisions of each is also divided into ten equal parts, by faint dots over the twelve parts; each one of these represent the one-teutb of a foot, when the primary division is taken for one foot. The Ivory and Boxwood Architect's Scales, with 16 different graduations, all brought to the edge. Nos. 410 and 458 have the same graduations on them as Nos. 406 and 454- but have them arranged in such a manner that the divisions of each graduation come out to one or the other of the four edges. The advantage of having the graduations on scales come out to the edges is, that the edge of the scale can be brought to the line, and the required distance marked off without taking it with the dividers, thereby in¬ suring greater accuracy and less trouble. PAPER SCALES. A very convenient though not very lasting scales ; are printed from copper-plates on strips of card-board ; they are nineteen inches long by one and a half inches wide • each strip has but one scale on it, and that on one edge. They are usually put up in sets of six, thus: J-, i, f, 1, 1J, and 3 inches to the foot, for series A; and A, ^ T K J. | and 1 of an inch to the foot, for series B; and 10, 20, 30, 40, 50. and 60 parts to the inch, for senes C. These scales being made of the same material as the paper upon which the drawing is made, the expansion and contraction, from moisture and heat, are equal upon both; another advantage is, they are not as liable to soil the paper as scales made of other material. STEEL RULES, OR SCALES. These scales are intended for the use of machinists, in making nice measurements on delicate work. They are made of steel, and divided into inches on all four of the ed°-es • the hist inch on one edge is divided into 16 equal parts, the next inch into 32 equal parts’, and the next into 64 equal parts. Another edge has the first inch divided into 20 equal parts, the next inch into 50 equal parts, and the next inch into 100 equal parts. Another edge has the first inch divided into 12 equal parts, the next inch into 24 equal parts, and the next inch into 48 equal parts; and the fourth edge has the first inch divided into 8 equal parts, the next inch into 14 equal parts, and the next inch into 28 equal parts. THE SECTOR. . These are usually made of two pieces of ivory, each six inches long, and jointed together like the carpenter’s rule; it is aD instrument but little used at the present time, and therefore we will not attempt to enter into a description of it here, but refer for complete information about its construction and use, to Heather’s Treatise on Mathematical instru¬ ments, page 34. STRAIGHT EDGES, Are rulers, the edges of which are very carefully finished, to enable the draughtsman to draw a perfectly straight line. They are made of some kind of hard wood” or metal. The metal ones can be made more accurately than the wooden ones, because their edges can be ground on iron plates, with emory, and finally finished by grinding the edges of two rules together, also with emory. In order to ascertain whether a straight edge is perfectly true, take two of them and place Que edge of one against an edge of the other, and hold them up between the eye JAMES W. QUEEN & CO., PHTUADELPHTA AND NEW YORK. 113 and the light, and observe if any light can be seen between the edges; all the ^-tgcs should be tried in the same manner. TRIANGLES Are used for laying off angles, and with a straight edge for drawing parallel lines. They are made of hard wood or metal, and are either solid or with open centre; the angles are usually 30, 60, and 90 degrees, or 45, 4 5, and 90 degrees ; the length of the sides vary from 5 to 12 inches. The wooden triangles are lighter, less expensive, and less liable to soil the paper than the metal, but cannot be made so accurately; the wood triangles are also apt to warp and become incorrect by wear in using. The advantage of the open over the solid triangles is, when of wood that they are less liable to warp and if of metal they are lighter; besides these reasons, they do not conceal so much of the drawing, and in using them the draughtsman can see better how to draw his lines. To see if the right angle of a triangle is correct, draw a straight line, and bring the edge of one of the sides exactly on it. having the right angle about the middle of it , then draw a line along the other side, f.om the right angle; now, it is to be supposed there is a right angle on each side of the last line drawn : to prove it, take up the triangle and place it in the same position it occupied before, but on the opposite side of the last line , now if the angle of the triangle is not 90 degrees, when one side corresponds with its line the other will not. To prove the angle of 30, see if it is one-third of ninety, and the angle of 60 should be double of the 30 angle. . , . t The edges of the triangle can be tested in the same manner as the edges of a straight edge The simplest way to test the right angle of a triangle, is by the right angle of the T square, one edge of the triangle being held against theblade and the two right^angles brought together; the other side of the triangle should fit evenly on the head of the T square; the other plan is the most correct, as there may be an error in the am.de of the T*square. The triangle is one of the most useful articles in a draughtsman s set of instruments. , IRREGULAR CURVES Are made of wood or horn ; a variety of curves are cut upon the outer edges, and pieces are cut from the body in such a manner that there is a curve for every side of the open¬ ing These curves are much used in design drawing, also for architectural drawing, some little use is made of them in civil engineering. T SQUARES Are usually made of hard wood, and are of three different kinds. The first kind has the cross-tdece or head fastened permanently and securely at right angles to the straight edge or blade. The second kind has the head attached to the blade by a clamp-screw, wlfich allows the head to be fixed at any angle to the blade, and firmly clamped where fixed The third kind has the head permanently and securely fastened at right angles to the blade, and a secondary head of the same size attached to it with a clamp-screw, and thus when other angles than right angles are to be made, the movable head can be fixed at the proper inclination to the blade, while a right angle is still maintained by the fixed head. ? In P the first two kinds the blade is fixed to one of the flat sides of the head and when used, the edge of the head comes against the side of the drawing board, while the blade lays Evenly on it; in the third kind the blade is attached between the t W o parts of the head, so ‘that in using either the fixed or movable side there is an edge to come against the drawing board, while the blade rests on the boa i • The T square is always used in connection with a drawing board and with and a triangle aU the straight and parallel lines of a drawing are very ea ily added; the head of the T square being held against the edge of the board, and the triangle resting against the ed which is fitted to this surface, and moves in it, must partake of its j irregularity, so that the glass and the line of collimation depending vl Lr upon it, though adjusted in one position of the slide will be thrown out when the slide is moved to a different point. To prove this, let any level be selected which is constructed in the usual manner, and the line of collimation adjusted upon an object taken as near as the range of the slide will allow; then let another be selected, as distant as may be clearly seen; upon this revolve the wires, and they will almost invariably be found out of adjustment, sometimes to an amount fatal tc any confidence in the accuracy of the instrument. The arrangement adopted by us to correct this imperfection, and which so perfectly accomplishes its purpose, is shown in the adjoining cut, Fig. F. Here are seen the two bearings of the object-glass slide, one being in the narrow bell-metal ring, which slightly contracts the diameter of the main tube, the other in the small adjustable ring, also of bell-metal, shown at C C, and suspended by four screws in the middle of the telescope. Advantage is here taken of the fact, that the rays of light are converged by the object-glass, so that none are obstructed by the contraction of the slide, except those which diverge, and which ought always to be intercepted, and absorbed in the blackened surface of the interior of the slide. Now, in such a telescope, the perfection of movement of the slide, depends entirely upon its exterior surfaces, at the points of the two bearings. These surfaces are easily and accurately turned, concentric, and parallel with each other, and being fitted to the rings, it only remains necessary to adjust the position of the smaller ring, so that its centre will coincide with that of the optical axis of the object- glass. When this has been once well done, no further correction will be necessary, unless the telescope should be seriously injured. The manner in which the adjustment of the object-glass slide is effected, will be considered when we come to speak of the other adjustments. Rack and Pinion. —As seen in the engraving, our Level tele¬ scopes are usually furnished with the ordinary rack and pinion movement to both object and eye tubes. The advantages of an eye-piece pinion, are, that the eye-piece can be shifted without danger of disturbing the telescope, and that the wires are more certainly brought into distiiict view, so as to avoid effectually any error of observation, arising from what is termed the instrumental parallax. The position of the pinion on the tube is varied in different in¬ struments according to the choice of the engineer. M Fig. F. JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 143 We usually place our object slide pinion on the side, both of Transit telescopes, and of those of the Level. The pinion of the eye tube is always placed on the side of the telescope. The Level or ground bubble tube is attached to the under side of the telescope, and furnished at the different ends with the usual movements, in both horizontal and vertical directions. The aperture of the tube, through which the glass vial appears, is about five and and one-fourth inches long, being crossed at the centre by a small rib or bridge, which greatly strengthens the tube. The level scale which extends over the whole length, is graduated into spaces a little coarser than tenths of an inch, and figured at every fifth division, counting from zero at the centre of the bridge; the scale is set close to the glass. The bubble vial is made of thick glass tube, selected so as to have an even bore from end to end, and finely ground on its upper interior surface, that the run of tho air bubble may be uniform throughout its whole range. The sensitiveness of a ground level, is determined best by an instrument called a level tester, having at one end two Y’s to hold the tube, and at the other a micrometer wheel divided into hundredths, attached to the top of a fine threaded screw which raises the end of the tester very gradually. The number of divisions passed over on the perimeter of the wheel, in carrying the bubble over a tenth of the scale, is the index of the delicacy of the level. In the tester which we use, a movement of the wheel ten divisions to one of the scale, indi¬ cates the degree of delicacy generally preferred for railroad engineering. For canal work practice, a more sensitive bubble is often desired, as for instance, one of seven or eight divisions of the wheel, to one of the scale. The Wyes of our levels are made large and strong, of the best bell-metal, and each have two nuts, both being adjustable with the ordinary steel pin. The clips are brought down on the rings of the telescope tube by the Y pins, which are made tapering, so as to clamp the rings very firmly. The Level Bar is made round, of well hammered brass, and shaped, so as to possess the greatest strength in the parts most subject to sudden strains. Connected with the level bar is the head of the tripod socket. The Tripod Socket is compound; the interior spindle, upon which the whole in¬ strument is supported, is made of steel, and nicely ground, so as to turn evenly and firmly in a hollow cylinder of bell-metal; this again has its exterior surface fitted and ground to the main socket of the tripod head. The bronze cylinder is held upon the spindle by a washer and screw, the head of this having a hole in its centre, through which the string of the plumb bob is passed. The upper part of the instrument, with the socket, may thus be detached from the tripod head; and this, also, as in the case of all our instruments, can be unscrewed from the legs, so that both may be conveniently packed in the box. A little under the upper parallel plate of the tripod head, and in the main socket, is a screw which can be moved into a corresponding crease, turned on the outside of the hollow cylinder, and thus made to hold the instrument in the tripod, when it is carried upon the shoulders. It will be seen from the engraving, that the arrangement just described allows long sockets, and yet brings the whole instrument down as closely as possible to the tripod head, both objects of great importance in the construction of any instrument. The Tripod Head has the same plates and leveling screws as that described in the account of the Engineer’s Transit; the tangent screw, however, is commonly single. For our sixteen inch Level we make a smaller tripod head, resembling that used with the lighter Engineer’s Transit. THE ADJUSTMENTS. Having now completed the description of the different parts of the Leveling Instru¬ ment, we are ready to proceed with their adjustments, and shall begin with that of the object-slide, which, although always made by the maker so permanently as to need no further attention at the hands of the engineer, unless in cases of derange¬ ment by accident, is yet peculiar to our instruments and therefore not familiar to many engineers. To Adjust the Object Slide. —The maker selects an object as distant as may be distinctly observed, and upon it adjusts the line of collimation, in the manner here- 144 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. after described, making the centre of the wires to revolve without passing either above or below the point or line assumed. In this position, the slide will be drawn in nearly as far as the telescope tube will allow. He then, with the pinion head, moves out the slide until an object, distant about ten or fifteen feet, is brought clearly into view; again revolving the telescope in the Y’s he observes whether the wires will reverse upon this second object. Should this happen to be the case, he will assume, that as the line of collimation is in adjustment for these two distances, it will be so for all intermediate ones, since the bearings of the slide are supposed to be true, and their planes parallel with each other. If, however, as is most probable, either or both wires fail to reverse upon the second point, he must then, by estimation, remove half the error by the screws C C, (fig. F,) at right angles to the hair sought to be corrected, remembering at the same time, that on account of the inversion of the eye-piece, he must move the slide in the direc¬ tion which apparently increases the error. When both wires have thus been treated in succession, the line of collimation is adjusted on the near object, and the telescope again brought upon the most distant point; here the tube is again revolved, the re¬ version of the wires upon the object once more tested, and the correction, if necessary, made in precisely the same manner. He proceeds thus, until the wires will reverse upon both objects in succession; the line of collimation will then be in adjustment at these and all intermediate points, and by bringing the screw heads, in the course of the operation, to a firm bearing upon the washers beneath them, the adjustable ring will be fastened so as for many years to need no further adjustment. When this has been completed, the thin brass ferule is slipped over the outside ring, concealing the screw heads, and avoiding the danger of their disturbance by an inex¬ perienced operator. In effecting this adjustment it is always best to bring the wires into the centre of the field of view, by moving the little screws A A (fig. F,) working in the ring which embraces the eye-piece tube. Should the engineer desire to make this adjustment, it will be necessary to remove the bubble tube, in order that the small screw immediately above its scale may be operated upon with the screw driver. The adjustment we have now given is preparatory to those which follow, and are common to all leveling instruments of recent construction, and are all that tb* engineer ill have to do with in using our own instruments. What is still necessary then is— 1. To adjust the line of collimation , or in other words, to bring both wires into the optical axis, so that their point of intersection will remain on any given point, during an entire revolution of the telescope. 2. To bring the level bubble parallel with the bearings of the Y rings, and with the longitudinal axis of the telescope. 3. To adjust the wyes , or to bring the bubble into a position at right angles to the vertical axis of the instrument. To Adjust the Line of Collimation, set the tripod firmly, remove the Y pins from the clips, so as to allow the telescope to turn freely, clamp the instrument to the tripod head, and by the leveling and tangent screws, bring either of the wires upon a clearly marked edge of some object, distant from one to five hundred feet. Then with the hand carefully turn the telescope half way around, so that the same wire is compared with the object assumed. Should it be found above or below, bring it half way back by moving the capstan head screws at right angles to it, remembering always the inverting property of the eye-piece; now bring the wire again upon the object and repeat the first operation until it will reverse correctly. Proceed in the same manner with the other wire until the adjustment is completed. Should both wires be much out, it will be well to bring them nearly correct before either is entirely adjusted. When this is effected, slip off the covering of the eye-piece centering screws, shown in the sectional view (fig. B,) at A A, and move each pair in succession with a small screw driver, until the wires are brought into the centre of the field of view. The inversion of the eye-piece does not effect this operation, and the screws are moved direct. To test the correctness of the centering, revolve the telescope, and observe whether it appears to shift the position of an object. JAMES W. QUEEN k CO., PHILADELPHIA AND NEW YORK. 145 Should any movement be perceived, the centering is not perfectly effected. It may here be repeated, that in all telescopes the position and adjustment of the line of collimation depends upon that of the object-glass; and therefore, that the movement of the eye-piece does not eff xt the adjustment of the wires in any respect. When the centering has been once effected it remains permanent, the cover being slipped over to conceal and protect it from derangement at the hands of the curious, or inexperienced operator. , To Adjust the Levee Bubble. —Clamp the instrument over either pair of leveling screws, and bring the bubble into the centre of the tube. Now turn the telescope in the wyes, so as to bring the level tube on either side of the centre of the bar. Should the bubble run to the end it would show that the vertical plane, passing through the centre of the bubble, was not parallel to that drawn through the axis of the telescope rings. To rectify the error, bring it by estimation half way back, with the capstan head screws, which are set in either side of the level holder, placed usually at the object end of the tube. Again bring the level tube over the centre of the bar, and adjust the bubble in the centre, turn the level to either side, and if necessary, repeat the correction until the bubble will keep its position, when the tube is turned half an inch or more, to either side of the centre of the bar. The necessity for this operation arises from the fact, that when the telescope is re¬ versed end for end in the wyes in the other and principal adjustment of the bubble, we are not certain of placing the level tube in the same vertical plane, and therefore, it would be almost impossible to effect the adjustment without a lateral correction. Having now, in great measure, removed the preparatory difficulties, we proceed to make the level tube parallel with the bearings of the Y rings. To do this, bring the bubble into the centre with the leveling screws, and then without jarring the instrument, take the telescope out of the wyes and reverse it end for end. Should the bubble run to either end, lower that end, or what is equivalent, raise the other by turning the small adjusting nuts, on one end of the level, until by estimation half the correction is made; again bring the bubble into the centre and repeat the whole operation, until the reversion can be made without causing any change in the bubble. It would be well to test the lateral adjustment, and make such correction as may be necessary in that, before the horizontal adjustment is entirely completed. To Adjust the Wyes. —Having effected the previous adjustments, it remains now to describe that of the wyes, or, more precisely, that which brings the level into a position at right angles, to the vertical axis, so that the bubble will remain in the centre during an entire revolution of the instrument. To do this, bring the level tube directly over the centre of the bar, and clamp the telescope firmly in the wyes, placing it as before, over two of the leveling screws, un¬ clamp the socket, level the bubble, and turn the instrument half way around, so that the level bar may occupy the same position with respect to the leveling screws beneath. Should the bubble run to either end, bring it half way back by the Y nuts on either end of the bar; now move the telescope over the other set of leveling screws, bring the bubble again into the centre and proceed precisely as above described, changing to each pair of screws, successively, until the adjustment is very nearly perfected, when it may be completed over a single pair. The object of this approximate adjustment, is to bring the upper parallel plate of the tripod head into a position as nearly horizontal as possible, in order that no es¬ sential error may arise, in case the level, when reversed, is not brought precisely to its former situation. When the level has been thus completely adjusted, if the instrument is properly made, and the sockets well fitted to each other, and the tripod head, the bubble will reverse over each pair of screws in any position. Should the engineer be unable to make it perform correctly he should examine the outside socket carefully to see that it sets securely in the main socket, and also notice that the clamp does not bear upon the ring which it encircles. When these are correct, and the error is still manifested, it will, probably, be in the imperfection of the interior spindle. After the adjustments of the level have been effected, aud the bubble remains in the centre, in any position of the socket, the engineer should carefully turn the tele¬ scope in the wyes, and sighting upon the end of the level, which has the horizontal adjustments along each side of the wye, make the tube as nearly vertical as possible. 10 \ 146 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. When this has been secured, he may observe, through the telescope, the vertical edge of a building, noticing if the vertical hair is parallel to it; if not, he should loosen two of the crosswire screws at right angles to each other, and with the hand on these, turn the ring inside, until the hair is made vertical; the line of collimation must then be corrected again, and the adjustments of the level will be complete. \ TO USE THE LEVEL. When using the instrument the legs must be set firmly into the ground, and neither the hands nor person of the operator be allowed to touch them, the bubble should then be brought over each pair of leveling screws successively, and leveled in each position, any correction being made in the adjustments that may appear necessary. Care should be taken to bring the wires precisely in focus, and the object distinctly in view, so that all errors of parallax may be avoided. This error is seen when the eye of an observer is moved to either side of the centre of the eye-piece of a telescope, in which the foci of the object and eye-glasses are not brought precisely upon the cross-wires and object; in such a case, the wires will ap¬ pear to move over the surface, and the observation will be liable to inaccuracy. In all instances, the wires and object should be brought into view so perfectly, that the spider lines will appear to be fastened to the surface, and will remain in that posi¬ tion however the eye is moved. If the socket of the instrument becomes so firmly set in the tripod head as to be difficult of removal in the ordinary way, the engineer should place the palm of his hand under the wye nuts at each end of the bar, and give a sudden upward shock to the bar, taking care also to hold his hands so as to grasp it the moment it is free. WEIGHT OF LEVELING INSTRUMENTS. The average weights of the different sizes of this instrument, exclusive of the tripod legs, are as follows : 16-inch telescope...11J lbs. 18-inch do....12 lbs. 20-inch do...12£ lbs. 22-inch do.13 lbs. THE BUILDER’S LEVEL. This instrument, shown in the engraving, is of much more simple and compact construction than those already described. It has a telescope of from eleven to twelve inches long, provided with the usual facilities for adjustment, resting upon the ends of the bar by two similar faces of the octagonal shaped prisms, which surround the tube at either end. The telescope is held on the bar by a stout screw at each end ; the heads of these screws are shown on the under side of the bar, and are bored to admit the usual ad¬ justing pin. A strong spiral spring is placed in a recess in the upper side of each end of the bar, and serves, in connection with the screws, to effect the third adjustment of the Level. These springs are of course removed, while the other adjustments are in progress, and the telescope allowed to rest directly upon the bar. The level is placed above the telescope and adjustable at either end by two nuts as shown. The instrument is best used upon the adjusting tripod, as represented, but may also be placed upon a simple ball spindle and used in connection with the leveling socket, shown in our account of the Solar Compass. The adjustments of this instrument are made in the same order, and almost precisely in the same manner, as those of the Engineers’ Level, described on pages 142 and 143, and need but a brief description. (1.) The line of collimation is adjusted, by making the wires reverse upon any given point, when the telescope is turned half way around, so as to rest upon opposite faces of the prisms. (2.) The Level is adjusted, by turning the telescope end for end upon the bar, the bubble being made to come to the centre in both positions. (3.) The bubble is brought into a position at right angles to the vertical axis, (the adjustment of the wyes in ordinary levels,) by releasing or compressing the springs JAMES W. QUEEN A 00., PHILADELPHIA AND NEW YORK. 141 at the ends of the bar, so that the bubble will come into the centre, as the instrument is turned upon its spindle, over both pairs of leveling screws in succession. The weight of this level, with adjusting tripod, excluding the tripod legs, is less than four pounds. TRENCH LEVELING INSTRUMENT. No. 1008 represents a very simple form of leveling instrument, well suited for giving the levels in ditching, or for any other occasions where very great accuracy is not required. It consists of a straight level bulb, about ten inches long, mounted on a straight bar of brass, to the ends of which, and at right angles to it, two upright pieces of brass are attached; near the top of these uprights, a horizontal cut is made in each, exactly at the same distance from the main bar. The bar with level and and sights is attached by a joint to a second bar of the same width, but much shorter. Through the second bar, and on the opposite end of it from the joint, a screw with milled head passes and presses against the under side of the main bar. To the second bar, a ball and socket joint is screwed, to which a tripod or jacob-staff can be fitted. After placing the instrument in position and leveling as near as possible by the ball and socket, it is accurately leveled by turning the milled head of the screw, which raises or lowers the main plate carrying the level and sights. CHAPTER XXIII. HAND LEVELS. In preliminary surveys the engineer finds it very convenient to have a pocket in¬ strument of some kind, for ascertaining approximately the relative levels of two distant points. No. 1016 represents one of these instruments. It consists of a square piece of brass, with stems attached to two of the opposite corners; to one of these stems a ball and socket is attached, having a small handle; to the other stem a screw with heavy head. A triangular cut is made through the square (see unshaded part of cut); a piece of fine plate looking glass is placed on the square and secured to it by a metal rim and screws; the part of the glass opposite the triangular cut has the silvering taken off; a fine line is drawn from corner to corner, across the face of the glass, cutting the base of the triangular opening at right angles. To use it, take it by the handle above the ball and socket, and hold the looking glass side about eighteen inches from the eye ; raise and lower the hand until the eye is seen on the line in the looking-glass, then run the eye along the line to the opening, and all objects on a level with the eye will be cut by the line. LOOK’S LEVEL. Another form of pocket level, called Lock's Hand Level, is represented by No. 1017. It is a brass or German silver tube, five inches long by three-fourths of an inch in diameter. One end has a draw tube, with half of a magnifying lens fitted in it; the other end is either open or fitted with a plain piece of plate glass; near this end there is an opening cut in the tube, and over it a spirit level is carefull}' adjusted; the frame which holds the spirit level has an opening cut in it directly over the opening in the tube, also one on the outside of the frame; directly under the opening in the tube a very small rectangular prism is adjusted, which occupies a little less than one-half the diameter of the tube; a fine line is drawn across the middle of the level. When the instrument is used, the e} r e is placed at the small hole in the end, and the draw tube pulled out until the line on the level is seen distinctly through the half lens and the prism ; now raise or lower very carefully the end of the tube which has the level on it until the centre of the bubble stands directly over the line, then all points at a distance which are seen through the vacant half of the tube and cut by the line, are on the same level as the observer’s eye. After a little practice, levels of considerable extent can be taken with either accurately. 148 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. THE CLYNOMETER. This instrument is used for ascertaining the angle of dip in rocks and the slope of embankments and excavations. It is a spirit level attached to an oblong bar of brass, which is hinged to a second bar of the same size; to the second bar a graduated arc is attached, which passes through a notch with clamp and screw in the side of the first bar. To use the instrument, clean a place upon the rock parallel with the dip or inclination of the strata; then place the flat surface of the second bar on it, and raise the bar with level until the bubble stands in the middle of the tube; then tighten the clamp screw, and the division of the arc which is on a line with the under side of that bar, is the angle of inclination. For taking the inclination of long lines, sights are attached to the bar which has the level on it. L. 0. STEPHENS’ PATENT COMBINATION RULE. The engravings illustrate an instrument invented by L. C. Stephens, and patented by him January 12th, 1858, which combines in itself a Carpenter’s Rule, Spirit Level, Square, Plumb, Bevel, Indicator, Brace Scale, Draughting Scale, T Square, Protractor, Right Angle Triangle, and with a straight edge can be used as a Parallel Ruler, all the parts of which in their separate application are perfectly reliable. It is made of boxwood, with one joint, and is well protected with heavy brass binding. The plate which protects the glass, being put on with screws, can be re¬ moved, should it by accident become necessary to insert a new glass. When folded it is six inches long, one and three-eighths inches wide, and three- eighths of an inch thick, and weighs the same as an ordinary broad bound rule. The cuts (which are exactly half size,) represent the rule in three positions: first, as a Spirit Level; second, as a Try-square Level and Plumb; third, as a Clynometer, or Slope Level , in which it is represented in taking the angle or inclination of an inclined plane—the top of a desk, for instance. The steel blade folds like a knife-blade into the part which holds it. On one side of the blade is graduated, and the figures 5, 10, 15, 20 to 45, denote the degree of the angles which are formed by opening the legs of the rule, the blade sliding through the groove in the end of the leg. When extended to 45 of course the angle is 45°, and the blade has fallen 27J° from a right angle or square. Hence the angles formed by the leg and blade decrease just one half as fast as the angles formed by opening the legs of the rule increase. The upper edge of the other side of the blade is also graduated into inches and eighths, and numbered l, 2, 3, 4, 5, 6, the graduations decreasing towards the end of the blade. This scale shows the pitch to the foot. Thus in the cut, which represents the rule as a Slope Level , the angle indicated is 9°, and the pitch of that angle or inclination, as shown on the other side of the blade, is seven-eighths and one-sixteenth of an inch on a base line of six inches , or one and seven-eighths inches on a base of one foot. By opening the rule 15°, the scale on the other side shows a pitch of one and five-eighths inches, in six inches, or two and three-eighths inches in a foot. The utility of these scales will be readily seen by those who have occasion to as¬ certain the angle or pitch to the foot of any inclined plane. The plumber, for instance, with this instrument can ascertain not only the angle, but the pitch to the foot of any roof. Engineers and artillerymen find the instrument invaluable, as by its aid any gun can be instantly adjusted to the proper degree of elevation. The inner edge of the leg which holds the glass is also graduated to measure the angles, which are formed by turning the blade in the leg which holds it, which ar¬ rangement is especially adapted to iron planers. These degrees show how much the right angle is reduced as the blade falls from that position. The machinist desires to reduce a piece of iron to a certain bevel, but instead of going to the planer “ to cut and try," as is usually done, he finds the degree of the angle he wants to apply the instrument to his pattern ; then by turning the index of the planer to the proper de¬ gree, he can cut the exact angle required. To apply it to a pattern, open the leg which holds the glass (keeping the blade down on the bottom of the groove) until the blade and leg in which it turns fit two sides of it, and observe the degree indicated by the blade. If at 40, then as before explained we know the pattern is just 20° less than a right angle or square, and to plane a piece of the same angle as the pattern, JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. 149 We place the index of the planer at 20°, the pattern being an angle of 70°, a^d \ 0 n -‘ 2u°=90—a right angle or square. This application of the instrument, all mechanics who understand it greatly admire. The pattern-maker, by using this tool, saves the machinist considerable labor, both working by the same degree. The surveyor will perceive its adaptation in the laying of angles. Open the part which holds the level until the end of the blade rests squarely upon the inside of it, and we have a T Square. In this position it is also a Right-Angle Triangle, and with the aid of a straight-edge can be used as a Parallel Ruler. One side of the blade is divided into twelfths, also the inside edge of the leg which holds it, which arrangement constitutes the Brace Scale. Place one point of the dividers on the third inch of the blade (while the rule is in form of a square,) and extend the other over to the third inch on the scale of twelfths on the inside edge of the leg, and the distance between the two points of the dividers applied to the scale of twelfths on the rule will give the length of the brace in feet and inches; inches and twelfths on the rule representing feet and inches in the brace, of course. The adaptation of this instrument to the measurement of height and distance is ob¬ vious from the following illustrations: A carpenter goes into the forest to find a tree which will furnish forty feet in length, of clear timber. He finds one which seems adapted to his purpose, but a bend or limb near the top leaves a doubt in his mind in regard to it. He now takes the instrument from his pocket and measures off forty feet in any direction from the tree, and marks the point where the measurement terminates; then fixes the leg which holds the level at an angle of 4F° and places the instrument upon this point, (taking care to keep it level;) then sights along tbc leg into the tree, and if the line of sight strikes below the bend or limb, he is safe in cutting the tree. To measure the height of a pole, tree, or house, adjust the rule to an angle of 45°, and recede from the object until a line of sight along the base of the instrument will strike the bottom of the object, and another through the raised leg will strike the top of it; then measure the distance from the point where the instrument stands to the foot of the object, and you have the elevation. (If necessary to elevate the instrument, the height from the bottom of the object must be added to give the true result.) To measure the distance to any inaccessible object, the width of a river, for instance, lay off a base line of any convenient length, adjust the rule to a square and place the base of the instrument upon the line, so that a line of sight from the blade will strike the object, and mark the point upon the line where you commence operations; then change the instrument to an angle of 45°, and move it along the £iven base line until the line of sight from the raised leg strikes the object as in the former position; then measure the distance from the joint of the instrument to the point previously marked, and you have the distance to the object. The slotted screw which passes through the end of the leg which holds the level is used in adjusting the square, should it wear so as to require it. With a small screw-driver the blade may be raised or de¬ pressed by turning this screw either way. The square is strong, firm and reliable, there being a heavy metal stop to prevent its going back too far, while it is held firmly in place, while in use, by a broad metal strap through which the screw passes. Carpenters, joiners, ship-builders, draughtsmen, engineers, and all classes of me¬ chanics are unanimous in the approval of this device, and the symmetrical arrange¬ ment of its parts. CHAPTER XXIV. GENERAL MATTERS, TRIPODS, In the tripods of all our instruments, the upper part of the leg is flattened, and fitted closely in the surfaces of the brass check pieces. The cheeks arc made very broad, and give a firm hold upon the leg, which may be tightened at any time by screwing up the bolts which pass through the top of the legs: this is especially necessary after the surface of the wood has been much worn. The legs are round, and taper in each direction from a swell, turned about one-third the way down, from the head to the point. 150 JAMES W. QUEEN & 00., PHILADELPHIA AND NEW YORK. The point, or shoe, is a tapering brass ferule, having an iron end; it is cemented, and riveted firmly to the wood. The legs of all our tripods are about four feet eight inches long, from head to point. We make three sizes of tripods, which we will now separately describe. 1. The Compass Tripod, seen in part in the cut of the Vernier Transit, and having the brass plate to which the cheeks are attached, three and three-fourth inches in diameter, and legs which are about one inch at the top, one and three-eighths at the swell, and seven-eighths at the bottom. The legs are usually made of cherry, sometimes of mahogany, and the tripod is used with the various kinds of compasses, and with the vernier transit. 2. The Medium Sized Tripod, shown with the Surveyor’s Transit, and having a plate of same diameter as above but with the cheeks made considerably broader, by curving at each end; the legs being also about an eighth of an inch larger throughout. This tripod has mahogany legs, and is used with the surveyor’s transit, the light engineer’s transit, and the sixteen inch level. 3. The Heavy Tripod, shown with the Engineer’s Transit, having a brass plate of four and one-fourth inches diameter, with extended cheek pieces, and with legs one and three-eighths of an inch at the top, one and three-fourths at the swell, and one and an eighth at the point. The heavy size has also mahogany legs, and is used with the engineer’s transit, and larger leveling instruments. LACQUERING. All instruments are covered with a thin varnish, made by dissolving gum shellac in alcohol, and applied when the work is heated. As long as this varnish remains, the brass surface will be kept from tarnishing, and the engineer, by taking care not to rub his instrument with a dusty cloth, or to expose it to the friction of his clothes, can preserve its original freshness for a long time. BRONZE FINISH. Instead of the ordinary brass finish, some engineer’s prefer instruments blackened or bronzed. This is done with acid preparation, after the work has been polished, and gives the instrument a very showy appearance, besides being thought advantageous on account of not reflecting the rays of the sun as much as the ordinary finish. LEVELING RODS. The three kinds used by American engineer’s are all sliding rods, divided into hundredths of a foot and reading by verniers to thousandths. PHILADELPHIA ROD. The leveling rod known as the Philadelphia Rod, is formed of two strips of light baywood or mahogany, each three-fourths of an inch by one and three-fonrths inches by six and one-half feet long, connected together by two metal sleeves, the upper one of which has a clamping screw, for fixing the rod in its position when the two parts are separated or extended, beyond six feet six inches. Both sides of the back rod and one side of tjie front rod are planed out one-sixteenth of an inch below the edges. These depressed surfaces are all painted white, and divi¬ ded into feet, and tenths of a foot. T-he front rod reads from the foot upward ; both sides of the back rod read downward. The feet figures are red, one inch long, and the one-tenth figures black, eight-tenths of an inch long. The target is an oval four by six and one-half inches, made of brass, with an opening, in its face, two and three-fourths inches long by one inch wide, with vernier on one side reading to one- hundreths. The upper sleeve has a vernier reading to one-hundredths on the back of the rod, for the rod-man to take the reading when the two parts are extended beyond six feet six inches. The advantage of this rod is that the engineer can check the rod-man’s reading to the one-tenth of an inch when looking through the telescope of his level. BOSTON ROD. That known as the Boston or Yankee Rod, is formed of two pieces of light haywood JAMES W. QUEEN k CO., PHILADELPHIA AND NEW YORK. 151 or mahogany, each about six and a half feet long, connected together by a tongie and sliding easily by each other, in both directions. One side is furnished with a clamp screw and vernier at each end, the other carries the divisions, marked on strips of satin wood, inlaid on either side. The target is a rectangle of wood, fastened near one end of the divided side, and having its horizontal line just three-tenths from the extremity. The target being fixed, when any height is taken above six feet, the rod is changed end for end, and the division read by the other vernier; the height to which the rod can be extended, being a little over eleven feet. THE NEW YORK ROD. This rod, which is shown in the engraving as cut in two, so that the ends may be exhibited, is made of satin wood, in two pieces like the former, but sliding one from the other, the same end being always held on the ground, and the graduations start¬ ing from that point. The graduations are made to tenths and hundredths of a foot, the tenth figures being black, and the feet marked with a large red figure. The front surface, on which the target moves, reads to six and a half feet; when a greater height is required, the horizontal line of the target is fixed at that point, and the upper half of the rod, carrying the target, is moved out of the lower, tho reading being now obtained by a vernier on the graduated side, up to an elevation of twelve feet. The mountings of this rod arc differently made by different manufacturers. We shall give those which we have adopted. The target is round, made of thick brass, having, to strengthen it still more, a rib raised on the edge, which also protects the paint from being defaced. The target moves easily on the rod, being kept in any position by the friction of the two flat plates of brass which are pressed against two alternative sides, by small spiral springs, working in little thimbles attached to the band which surrounds the rod. There is also a clamp screw on the back, by which it may be securely fastened to any part of the rod. The face of the target is divided into quadrants, by horizontal and vertical diame¬ ters, which are also the boundaries of the alternate colors with which it is planted. The colors usually preferred are white and red: sometimes white and black. The opening in the face of the target is a little more than a tenth of a foot long, so that in any position a tenth, or a foot figure, can be seen on the surface of the rod. The right edge of the opening is chamfered, and divided into ten equal spaces, cor¬ responding with nine hundredths on the rod ; the divisions start from the horizontal line which separates the colors of the face. The vernier, like that on the other side of the rod, reads to thousandths of a foot. The clamp, which is screwed fast to the lower end of the upper sliding piece, has a movable part which can be brought by the clamp screw firmly against the front sur¬ face of the lower half of the rod, and thus the two parts immovably fastened to each other without marring the divided face of the rod. CHAINS. SURVEYOR’S CHAINS. Four Pole Chains.—T he ordinary surveyor’s chain is sixty-six feet, or four poles long, composed of one hundred links, each connected to the other by two rings, and furnished with tally marks at the end of every ten links. In all the chains we manufacture, the rings are oval, are sawed, and well closed, the ends of the wire forming the hook being also filed and bent close to the link s-.* as to avoid the danger of “ kinking.” A link in measurement includes a ring at each end. Tlic handles are of brass, and each forms part of the end links, to which it’s ton ■ nected by a nut, by which also the length of the chain is adjusted. The tallies are also of brass, and have one, two, three or four notches, as they ari ten, twenty, thirty or forty links from either end; the fiftieth link is rounded, sc as o distinguish it from the others. 152 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. Two Pole Chains. —In place of the four pole chain just described, many surveyors prefer one of two rods or thirty-three feet long, having but fifty links, and counted by its tallies from one end in a single direction. Sizes of Wire.— Our surveyors’ chains are made of the best refined iron wire, of sizes Nos. 7, 8 and 9, as may be preferred; the diameter of No. 9 wire being about one- eighth of an inch, and that of No. 8 wire nearly a sixteenth larger. ENGINEERS’ CHAINS Differ from the preceding, in that the links are each 12 inches long; the wire, also, is usually much stronger. They are either fifty or one hundred feet long, and are furnished with handles, tallies, &c., and sometimes with a swivel in the middle to avoid being twisted in use. In place of the round rings commonly made, we have substituted in these and our other chains, rings of an oval form, and find them almost one-third stronger, though made of the same kind of wire. Sizes of Wire. —The wire used for these chains is commonly of No. 7. The wire is of the first quality, and the whole chain is made in the most accurate and substantial manner. STEEL CHAINS. Chains made of steel wire, though more costly than those which we have just de¬ scribed, are yet often preferred on account of their greater lightness and strength. They are made of any desired size or length, generally of No. 10, rarely of No. 8 wire, and are very stiff and strong. Brazed Steel Chains. —A very portable and excellent measure is made, by a light steel chain, each link and ring of which is securely brazed , after being united together and tested the wire is also tempered. The wire generally used by us is of size No. 12, the rings are of oval form, the chain, though exceedingly light, is almost incapable of being either broken or stretched. Our steel brazed chains have been found exceedingly desirable for all kinds of measurement, and for the use of engineers upon railroads and canals have almost entirely superseded the heavier chains. GRUMMAN’S PATENT CHAINS. These chains, invented and patented by J. M. Grumman, of Brooklyn, N. Y., are made of very light steel wire, the links being finely tempered, and, as shown in the illustration, so formed at the ends as to fold together readily, and thus dispense with the use of rings. This construction gives only one-third as many wearing points as the ordinary chain, and affords the utmost facility for repairs, from five to ten extra links being furnished with each chain, which have only to be sprung into place to replace such , as may have been broken ; it can also be taken apart at any link, and, having a spring- catch on either handle, be made of any length desired. These chains are made of three different sizes of wire—the first two, termed drag chains, being of size No. 12 and 15, and used for measuring on the surface, like the ordinary chain; and the second, called the “suspended chain,” for very accurate measurements, made of No. 18 wire, and with spring-balance, thermometer and spirit level attachments, to be held above the surface when in use, the extremities of the chain being marked upon the ground by the points of plummets let fall from the ends of the chain. .The drag-chains are all that are needed in common land surveys; for a mixed ■ practice of village and country surveying, the spring-balance should be attached to the drag-chains, while for city surveying the suspended chain, with all its attach¬ ments, is the proper instrument. A more complete description of these chains, and of chain measurements in gene¬ ral, written by the inventor, will be sent by us to any one applying for the same. We have purchased the patent for the Grumman chains, with the entire right to make and ; sell them, and shall hereafter be able to furnish them promptly. MARKING PINS. In chaining, there are needed ten marking pins, or chain stakes, made either of iron, steel,or brass wire, as may be preferred, about fourteen inches long, pointed at JAMES W. QUEEN k CO., PHILADELPHIA AND NEW YORK. 153 one end to enter the ground, and formed into a ring at the other, for convenience in handling. They are sometimes loaded with a little mass of lead around the lower end, so as to answer as a plumb when dropped to the ground, from the suspended end of the chain. TO USE THE CHAIN. In using the chain its length must be taken from its extreme ends, and the pins placed on the outside of the handles ; it must be drawn straight and taut, and care¬ fully examined to detect any kinks or other causes of inaccuracy. Our chains are all carefully tested at every ten, sometimes at every link, and in their whole length by the U. S. standard, and when new may always be relied upon as correct. But as all will alter, more or less, after long use in the field, it will be best for the surveyor to carefully lay down on a level surface the exact length of the chain when yet new, marking also its extreme ends by monuments which will not be liable to disturbance. He will thus have a standard measure of his own to which the chain can be ad¬ justed from time to time, and again be used with perfect confidence. TAPE MEASURES. The best are Chesterman’s steel tapes, made of a thin ribbon of steel, which is jointed at intervals, and wound up in a leathern case, having a folding handle. These tapes are of all lengths, from three to one hundred feet, divided into inches and links, or tenths of a foot, and links, the figures and graduations being raised on the surface of the steel. The next best and most commonly used are Chesterman’s metallic tape measures. These are of linen, and have also fine brass wires interwoven through their whole length. They are thus measurably correct, even when wet. They are mounted like the steel tapes, of like lengths, and similarly graduated. The best linen tape measures No. 10G5 are wove of linen only, and are varnished to prevent the moisture from expanding or contracting them. CHAPTER XXV. INFORMATION TO PURCHASERS OF SURVEYING COM¬ PASSES, TRANSITS AND LEVELS. Instruments Wanted. —In regard to the best kind of instruments for particular purposes, we would here say, that where only common surveying or the bearing of lines in the surveys for county maps is required, a plain compass is all that is neces¬ sary. In cases where the variation of the needle is to be allowed, as in retracing the lines of an old survey, &c., the vernier compass or the vernier transit is required. Where, in addition to -he variation of the needle, horizontal angles are to be taken, and in cases of local attraction, the railroad compass is preferable ; and for a mixed practice of surveying and engineering, we consider the surveyor’s transit superior to any instrument made by us or any other manufacturers. In the surveys of U. S. public lands, the county and township lines are required to be run by such instruments as the solar compass. Where engineering is the exclusive design, the engineer’s transit and the leveling instrument are of course indispensable. The builders’ level is intended for laying out mill seats and determining the levels of buildings in course of erection. Warranty. —All our instruments are examined and tested by us in person, and are Bent to the purchaser adjusted and ready for immediate use They are warranted correct in all their parts—we agreeing in the event of any 154 JAMES W. QUEEN & CO., PHILADELPHIA AND NEW YORK. defect appearing after reasonable use, to repair or replace with a new and perfect in¬ strument, promptly and at our own cost, express charges included, or we will refund the money and the express charges paid by the customer. Instances may sometimes occur, in a business as largely and widely extended as ours, where, owing to careless transportation, or to defects escaping the closest scrutiny of the maker, instruments may reach our customers in bad condition. We consider the retention of such instruments in all cases an injury very much greater to us than to the purchaser himself. Packing, &c. —Each instrument is packed in a well finished mahogany case, fur¬ nished with lock and key and brass hooks, the larger ones having besides these, a leather strap for convenience in carrying. Each case is provided with screw drivers, adjusting pin and wrench for centre pin, and, if accompanied by a tripod, with a brass plumb-bob ; with all instruments for taking angles, without the needle, a reading microscope is also furnished. When sent to the purchaser, the mahogany cases are carefully enclosed in outside packing boxes, of pine, made a little larger on all sides to allow the introduction of elastic material, and so effectually are our instruments protected by these precautions, that of several thousand sent out by us during the last twenty years, in all seasons, by every mode of transportation, and to all parts of the Union and the Canadas, not more than three or four have sustained any serious injury. Finish of Instruments. —Customers ordering instruments, will do us a favor by mentioning whether they prefer them of bright, or bronze finish, the cost being the same in either case. If no direction is given, we usually send instruments finished bronze. Terms of Payment are aniformly cash, and we have but one price, whether ordered in person or by mail. Our terms are as low as we think instruments of equal quality can be made, and will not be varied from the list given on the previous pages. v REPAIR OF INSTRUMENTS. Many instruments of our own and others’ make, come to us every year for refitting and repairs, and so much correspondence arises therefrom, that we are led to believe that a brief statement in this place, of the cost of such repairs, &c., will be of service to our customers and ourselves. Most instruments sent to us for repairs are injured by falls; many are worn and defective in parts after long use ; and others are sent for repolishing and renovation. We advise our customers having instruments in need of repairs, &c., to send them immediately to us, as our facilities enable us to do the work much more economically and promptly than any other maker however accessible. They should always, when practicable, be placed in their own boxes, and these in¬ closed in an outside packing case, an inch larger in all its dimensions, that the interval between the two may be filled with paper wadding, hay or fine shavings. A note, specifying the repairs needed, should accompany the instrument, and a letter should also be sent by mail to us, giving not only directions as to the repairs, but also stating when the return of the instrument is required, and the precise location to which it should be forwarded. It should also be remembered that each instrument is made to fit its own spindle and no other; and therefore this part with the parallel plates and leveling screws, if it has any, should always be sent with it. The legs and brass head in which they are inserted need never be sent, unless themselves in need of repairs. Compasses. —These come to us with the plates sprung, the sights bent or broken, the glass or level vials fractured, and the pivot so dulled as to render the needle sluggish and unreliable. The cost of repairing the defects above named, ranges from 2 to 8 or 10 dollars. A new pair of sights fitted costs 6 dollars; a new needle, with jeweled centre and pivot complete, $8.00; a new jeweled centre, $2.50. The compass should always be accompanied by the ball spindle, and if a new ball spindle is required, the whole instrument, or at least the socket in which the spindle ■ * JAMES W. QUEEN k CO., PHILADELPHIA AND NEW YORK 155 fits, should be sent with the letter of advice to us: a new ball spindle costs two dollars. Transit Instruments. —The repairs of the Vernier Transits cost about the same as those of the compasses above stated. The injuries sustained by the falls of Engineers' and Surveyors’ Transits are usually much more serious ; in these the plates, standards and cross-bar of telescope are often bent, and the sockets or centres usually so deranged as to be entirely useless. The cost of repairing an instrument with such injuries, ranges from 10 to 30 or even 50 dollars, the new sockets alone costing from 10 to 20 dollars. Leveling Instruments are generally much less injured by falling than Transits, the damages being included usually in the bending of the cross-bar, the springing of the sockets, and the breaking of the level vial. The cost of repairs varies from 5 to 15 dollars; a new level vial set in the tube eosts two dollars. Re-Polishing Instruments. —The cost of re-polishing an instrument, involving also of course its complete renovation and adjustment, varies with the different kinds, but may be stated generally as follows: Compasses, from.$5 to $8. Transits, do.10 to 16. Levels, do.10 to 13. No additional charge is made for bronzing or blackening an instrument when re¬ polished. Payment of Repairs, &c., may be made at the express office where the instrument is received, the customer paying for the first transportation of the instruments to us or not as he may prefer. Whenever the freight is paid in advance, the express receipt should be mailed immediately to us. INDEX. CHAPTER I. Mathematical Instruments Brass, CHAPTER II.
