Part I is devoted to the description of American Woodworking machines for vocational schools. Part II has to do with the operation of some of the machines with the view of helping the student to a better understanding of the correct position to take at the various machines he will be called upon to operate. Part III is of primary interest to the teacher or director of vocational work, especially to those on whom fall the responsibility for specifying equipment for their schools. The guiding principle in the construction of our machines rests solely on the nature of the work they are to perform. Our engineers are constantly seeking the highest requirements of the trade and making improvements accordingly. We have kept pace with the highest developments in electrical drives. The direct application of both A. C. and D. C. motors to saw arbors and cutter heads, as illustrated in this catalog, are original and exclusive with us. When a motor goes on an American machine it becomes a part of the machine itself (see our Headblock Lathes, Jointers, Saw Benches and Surfacers); you will find no clumsy makeshift arrangements here. Please file this book where you can get hold of it when you need anything in woodworking machinery. American Wood Working Machinery Company Rochester, N. Y.

The Men Who Work in Wood The men who work in wood! — here is a clan That other workers well may envy- — these Who serve so much, so well, their fellow man, Who turn to use the tall and sheltering trees. The roof of green becomes a roof of gray, The sturdy trunk the pillars of a home. They fashion us the infant's cradle, they Are part of every threshold, every room. The chair we dream in by the cheery fire, The board at which we gather for the meal, The bed to which our weary limbs retire, And everything we know and love and feel They shape from fallen forests for our need — Yea, even that last room in which we rest. When we lie down to rest at last indeed, The woodland's sainted lily on our breast. Theirs not the dust of mines, the grime of toil In sweaty shops of steel and molten brass — Theirs is the scent of sawdust and of soil The song of waters, wind across the grass. In everything they make for us they leave The wooded upland and the quiet shores, Yea, into every article they weave Some memory of God's great out-of-doors. — Douglas Mallock In American Lumberman.

No oiling. No sticking Simple, substantial, practical design Beveled guide plates on both guides Open construction insures free movement. No clogging The Newell Automatic Saw Guide TN the Newell Automatic Saw Guide the grinding members, instead of being rigid as in all other guides, have a swinging movement which allows the back of the saw to swing freely while the teeth are held practically stationary. With these Guides the operator can force the saw around the short- est curve without kinking or straining it. Deep cuts can be made straight from top to bottom without dishing out, thus enabling the operator to saw close to the line of his work without spoiling it or making a lot of hand finishing necessary. The swinging movement of the Newell Guide compels the saw to follow true to the line of pressure. Any tendency for the saw to deviate causes the guide to react upon it immediately, thereby correcting the deviation. There is great economy in the use of the Newell Guide inasmuch as the saw breakage as compared with any other guide is considerably reduced. Combination Band Saw Filing, Setting and Jointing Machine THIS is the only machine made that performs the two operations of filing and setting the band saw at one time. This places it in a class by itself, there being none similar to it on the market. The powerful elliptical movement of the filing arm, working between heavy adjustable bronze slides, guided by vertical rods set at an angle, is mechanically perfect. It gives each tooth a clean, sharp cut, and can be so delicately adjusted as to leave the teeth without a particle of burr. All teeth are filed and jointed to an exact uniform height and size. It means less breakage of saws, longer life, quicker work, and smoother and better cutting. The setting device not only sets the teeth perfectly, but also each tooth in such a way as to allow the proper clearance behind the cutting edge. All wearing parts are made of steel, and the vise, through which the saw passes, is steel lined. The time it takes to file, set and joint band saws in one operation, is only a fraction of the time occupied in hand filing. Standard files, \y 2 " extra slim taper or 7" slim taper, are used Figure 1260 American Band Saw Brazer THE illustration shows a new device for heating the joint with a flame and blowpipe, which overcomes the objections to the old method and is proving very satisfactory in practice. The Saw Blade is beveled or "scarfed" for the lap, on the table, which is machined true on the face and back, and suitable damps hold it while being operated upon. The Blowpipe is supplied with air from a double-acting pump with receiving chamber, fitted with good leather valves and double-cup piston packing. The capacity of the pump is much greater than the requirements, and very little exertion is needed to get sufficient heat to braze saws \}i" wide. The Lamp is attached to the machine, and has a very large ellip- tical wick, giving a long, steady flame which becomes hottest at the point where it is forced against the saw by the air blast. Kerosene is used for fuel. The Brazer is made ready for use by simply clamping it or screw- ing it to a bench and attaching the blast hose. We furnish brazer complete, one piece of hose, a quantity of prepared spelter and pulverized borax, some fine tying wire and full directions for braz- ing with either spelter or silver solder. The time required for scarfing down the ends of the blade, adjusting it and completing the braze is from eight to fifteen minutes, dependent on the width of the blade and skill of the operator.

The Filing Wheels and studs are made plain but serviceable, and are designed to be attached to a bench, as indicated in cut. We do not furnish the plank shown. The wheels are covered with heavy canvas, and the right-hand one adjusts horizontally to strain the blade. The Vises are made with jaws either 10" or 18" long. When an outfit is ordered we furnish the one 10" long unless otherwise stated. There are adjustable stops in the vises, so that the blade will not sink when filed. The jaws are planed true and will grip the whole length of the vise. The Brazing and scarfing frame for holding the saws when they are to be joined can be placed in the vise or screwed to a bench, which- ever is the most convenient. The entire outfit is simple and all that is necessary where a small amount of this work is to be done. Fig. Style Weight, lbs. Boxed foi Wt., lbs. ■ Export Cu. ft.

It will rip to widths leaving the edges perfectly straight at a rate equal to the output of two or three hand-fed saws. All the adjustments are in sight and are made from the front of the machine. Capacity — Will rip stock as short as 8" and to 24" wide. Distance from saw to left hand of table 24". Largest diameter of saw used 14"; smallest, 10". A 14" saw will rip stock 4" thick and under. A 12" saw is furnished with the machine. Hole is l£l$" with ^" dowel pin IjV' from centre of saw to centre of pin. A jointing stone and holder are furnished. Technical Features Main Column — -Is the cored type, exceptionally heavy and strong, making a rigid support for the saw and the upper feed works. It is gibbed to the frame in heavy ways in such a manner that when clamped to the frame by the clamp lever it is absolutely free from vibration. It is adjusted by a screw with ball end-thrust bearing operated by a large hand wheel at the front of the machine. Arbor — Is 2" diameter and runs in three self-oiling bearings. Pul- ley, 8"x7", speed 3000 to 3400 R.P.M. Sight feed oil cups are provided. Feed Works — Consist of an endless-feed chain in the table with pressures above to keep the stock in firm contact with the chain. There is an in-feed and an out-feed pressure roll of large diameter. The in-feed roll is driven, thus making it more positive in entering stock for straight ripping. Rolls are horizontally mounted on hinged arms and have independent vertical adjustment with spring pressures applied to each. This affords flexibility that per- mits the stock to enter the rolls easily. The arms of both the in- feed and out-feed rolls can be adjusted so they can be kept in perfect alignment with the saw and the feed chain. The saw and rolls are entirely enclosed making an efficient suction hood. The hood is ad- justable on a screw with ball bearing end-thrust operated by an over- head handwheel and has graduated scale to indicate height of the rolls. There is also a kick-back or sliver guard back of the in-feed- ing roll which makes a complete protection for the operator. The front of the roll hood is provided with a sight that indicates the location of the saw for sighting the cut. A section of the circular hood for the saw can be removed for changing saws by loosening two hand wheels and the suction pipe does not have to be removed. Three rates of feed, usually_60, 120 and 160 lineal feet per minute are provided. Quick change of feed is made, without throwing off the power, by lever at the left of operator. Binder lever controlling the feed is at the right of operator. The driving mechanism on the right side of the machine for the endless feed chain and in-feed roll consists of steel roller chain and feed pulley which are entirely en- closed. Table — Is fitted with an endless chain which travels on an independent bed plate with the wearing surfaces lined with steel. It can be adjusted vertically to insure perfect contact with the stock on the table. The adjustment is made by hand wheel and screw from the in-feeding end of the machine. The front end of the bed is also adjustable, transversely to and from the saw. This insures perfect alignment with the saw at all times. Sight-feed oil cups are provided at the right-hand side of frame for lubricating the chain. Countershaft (furnished as an extra) — Is provided with tightener for drive belt with 12"x8" T. & L. (self-oiling loose) pulleys; speed 1000 R.P.M. Motor Drive— Can be supplied by mounting motor on a special bracket which takes the place of the usual outer bear- ing, a flexible coupling connecting the motor shaft direct to the saw arbor.

It will cut a perfect miter; it will mea- sure any angle instantly and accu- rately; it will cut off to length or rip to width — all without the operator having to do any previous calculat- ing or even referring to a rule. Capacity — Rips from I 1 „" to 27 r 2" and cuts off to 31" wide when saw is set for 2" thick. An 18" saw may project 5K" above the table. The table tilts to 45° for bevel sawing. Two 18" saws l l A" hole are furnished. If necessary one 20" saw (not adjustable) can be used. Dado heads 2><" wide can be used. Technical Features Frame — Is a unit casting, massive and rigid, having three points of bearing on the floor. Table — Size 40"x48". The movable section is 17" wide, guided by an accurately fitted tongue and groove and sup- ported on adjustable anti-friction rollers. It can be drawn away from the main table 3" for dado work. Main section is 23" wide, and is ruled for ripping up to 21 l / 2 " wide. The entire table can be tilted to 45° by means of a worm and worm segment. The segment is ac- curately graduated and can be clamped at any point, and there is a fixed stop on the frame for the horizontal position. Gauges — There are four gauges, three for cutting off and one for ripping. The prin- cipal cutting off gauge is pivoted to the sliding section and can be stopped at the principal angles with a taper pin, and by a patented attachment all intermediate angles can be quickly found. We apply also in connection with this gauge our patent graduated sector on the table, by which stock can be cut to required angle without calculation when the length is known. The two swivel cut-off gauges move in a slot in each section of the table. The supporting tongues extend the whole length of the table and can be reversed when not in use, maintaining an unbroken table surface. The ripping gauge is adjusted by taper pins and micrometer rack and pinion and can be used on either side of the saw. The stationary table is ruled across its face for accurate ripping.

Our experience dates back over twenty years, and thousands of our planers are in use in many of the leading wood shops in this and other countries. They are in furniture, chair, in- terior trim, carpenter, pattern, box, sash and door, auto- mobile, wagon and implement factories, and in many of the leading manual training schools. Capacity— Made in three widths, 24", 30" and 36", and to 7" in thickness; pieces from 4" long up can be sur- faced true. Feed from 18 lineal feet per minute upward according to the requirements of the work. Usually two rates of speed are furnished, 22 ft. and 30 ft., but with the variable feed the maximum can be 85 ft. With our patent sectional roll and chipbreaker, narrow strips of varying thickness can be surfaced simultaneously, thus increasing the capacity of the planer several hun- dred per cent. 31 Technical Features Feed Rolls — Are 5" diameter, all driven, and, unless otherwise ordered, turned smooth, except the upper in-feed roll which is corru- gated. Our patented sectional in-feed roll has no rival for power, durability and convenience. Each section carries eight tempered tool steel springs 2}/&" long, and repairs, under reasonable working condi- tions, are rare. The construction is such that an entire roll can be taken apart and reassembled in a few minutes. Sections and drivers are of hardened steel. Roll shafts are held down by long range tempered steel springs adjustable for tension. Feed Drive — Is by belts in the high speed portion of the transmission, hardened steel roller chains for the intermediate, and cut gears for the rolls or slow portion. This makes for simplicity, economy of power and smooth action of the rolls, all necessary conditions for a high grade planer feed. Cylin- der — Is of hard forged steel, triangular with three knives or round with thin knives if desired. Journals are 2%" diameter, care- fully ground and lapped. Boxes are of the side clamping type with automatic circulation of oil and emergency oilers in the caps. Pneumatic cylinder pulleys 5"x5K" are clamped on to conical bearings. Ball bearings can be furnished at an extra price. They consist of two pairs of bearings to each journal with steady collars between each pair and ample facilities for oiling, the require- ments being much less than for the babbitt bearings. Chipbreaker — Is made solid or sectional to correspond with the in-feed roll. It adjusts in grooves concentrically to the cylinder and can be lifted out when required. When made solid, it can be lipped with flexible steel. Sections are of hardened steel. Pressure Bar — Hangs close to the cylinder and is adjustable at either end by finger wheels; it is ordi- narily made yielding, but may be rigid and adjustable in height when so ordered. Bed Plate — (In three sections) is machined on entire surface; the center section lies under the cylinder and is removable for any purpose; the in-feed and delivery sections are usually slightly below the line of the cylinder bed, but can be adjusted to suit conditions. Main Bed — Is supported on heavy inclines, which move on tracks cast upon the frame. The machined surfaces are scraped to a bearing and ample provision is made for oiling. The adjustment for thickness is made by means of two square threaded screws coupled together and operated by a large central hand wheel and cut gears. Knife Jointing and Setting Attachments-^Are extra and consist of a permanent slide bar secured to the frame over the cylinder on which the setter and jointing slide move and may be pushed to the end of the slide bar when not in use. When ordered a knife grinder can be put in place of the jointing plate, usually motor driven. Motor Drive — For belted planers we can furnish a special motor with extended shaft to receive pulleys at each end to drive the cylinder. This can be located on the floor behind the planer or overhead. For simplicity and economy of room and belting, we recommend our new directly attached motor secured to the cylinder on a taper with holding nut. Motor frame is bolted up to a supporting bracket directly attached to the machine frame and is adjustable to concentricity with the rotor. Counter- shaft—Has T. & L.

The first two are of the same construction, the last is simply a square cylinder with the sides capped with bars which give it a round cross section. This cylinder has two sides slotted .which permit the use of moulding cutters (by_ detaching the caps), and two sides with knives. It will be seen that the construction of our two and three-knife safety jointer cylinders is very simple, con- sisting of a steel forging turned round and with slots planed length- wise to receive the thin knives and knife clamping blocks with provision for adjusting the knives. In fact, the simplicity and absolute safety of these heads over others have recommended them to many of the best mills everywhere, and they are passed by insurance companies and state inspectors invariably. The Four-Capped Safety Jointer Cylinder with dovetail slots for attaching special knives for variety work is strictly a special head with us, and is furnished on our machines only on special order. The knives furnished with each head depend upon the quality and temper of steel desired. Unless otherwise specified we furnish special steel knives tempered to file cr grind. High speed, hard steel knives are extra. The grade of knife should be specified when ordering the cylinder. American Patent Round Surfacer Cylinders We have been manufacturing Round Surfacer Cylinders for many years and are prepared to supply the most critical users with the best that money can buy. We make them up to 8}4'' in diameter with two, three, four, six and eight knives, the number of knives depending upon the nature of work to be done and the machine to which the head applies. The construction of these heads is simple, consisting of the same fundamental features described above, varying only in detail as the purpose requires. American Thin Special Steel Knives Our thin jointer knives are yi" thick and ground parallel all over. We can furnish them to file or to grind for sharpening. The best knife for surfacers is made from special steel, heat treated by experts with the most modern equipment and is a product recom- mended for fast feeds and high speed. These knives are the last word in high grade woodworking knives, and we know from experi- ence will meet all reasonable requirements on hard or soft wood at high speeds. They are strictly guaranteed as to material and workmanship. All knives are yi" thick and usually 8", 12", 16", 20", 24", 27", 30" and 36" long. Standard widths are 1%", IK", W, W, \%" and \i/i". Special widths can be made to order. CM r^ 3 -a oo o 6 c a o 42 American No. 505 Fast Feed Four Side Moulder OUR No. 505 is an advanced type of American Moulder.

End platen swings down out of way to give access to knives, and is cushioned by a spring. Feed — Consists of four power-driven rolls with cut gears and driven by hardened roller chain and sprockets inside the frame; controlled from either end of machine. Top rolls are 5K" diameter with removable outside bearing. A heavy equalizer bar on inside of frame connects with the top feed roll yokes and keeps the rolls parallel with the face of the bed — preventing any twist or strain on shafts or gears. Top rolls lift by means of lever near operator. Lower feed rolls are 6" diameter and may be removed without dismant- ling the machine. Rates of feed, 15, 25, 44 and 75' per minute, with lever gear shift controlling two rates at a time. Cutter Heads — Top and bottom heads are the slip-off type and the spindles run in heavy side clamping boxes with screw adjustment. Outside bearings for both heads adjustable in gibbed slides and detachable. All heads, including side heads, have cutting circle of 6 l A". Outside bearing stand securely clamped to frame of machine; adjustable for lining up when necessary. Arbors are crucible steel, 1 13/16" diameter where head goes on, 2%" diameter in bearings. Chipbreaker adjusts to and from cutters; slides back out of the way to give access to knives. Pressure foot is hinged on the chipbreaker proper, with springs in the hinge, to avoid vibration, and adjusts independently. Pressure Bars, in rear of top head and over bottom head, are sectional; adjust hori- zontally and vertically; are hinged and swing up over the frame, leaving table and side heads clear. Bearings have dust-proof oilers and com- pression grease cups. Side Headstocks — Both are securely attached to the table — making vibration impossible. Both adjust vertically and laterally. The outside headstock may be set to an angle. The angular adjustment is obtained by a horizontal screw at the lower end of the headstock, which moves the head on a circle, the center of which lies on a plane with the face of the table. The angular adjustment once made, is not affected by the vertical and lateral adjustments of the headstock. Inside head has chipbreaker and take-up. Outside head has weighted, reciprocating matcher clip attached to the movable block carrying the headstock and moves in and out with the headstock. The opening in the bed for the outside head has an adjustable mov- able plate for carrying wide material. For narrow stock this may be removed. Side spindles are crucible steel 1 13/16" in diameter where heads go on and are mounted in our side clamping boxes and run on self-oiling pivoted steps. Countershaft — Size of driving pulleys are as four to one in relation to all cutter head pulleys, giving excellent belt contact. T. & L. pulleys are self-oiling 12"x8", and should make 900 R.P.M.

It is made in both the sizes as the other types of the series are. As the illustration indicates the rotors of the motors are secured to the spindles in place of the usual pulleys. 7200 R.P.M. is the speed recommended for the spindles, and at this speed the motors develop 4 H.P. each. In order to obtain this speed, a frequency changer is required which generates 120 cycle. When a number of shapers are located near each other, one frequency changer serves them all. These motors are made specially for these machines and are always for alternating current, 3 phase, 120 cycle, 220 volts. Ample appliances are provided for protecting the parts, together with all conveniences for lubrication, adjustments and manipulation. The electric connection and control are attached to the frame of the machine, making it a unit construction. The advantages of this construction are: elimination of counter- shafts and belts, saving of much floor space, flexibility of operation and a greater economy of power and operating expense. The general description of our Type A Shapers is the same as that of the others of the series 20 and 30. Fig. Style Floor Horse- Wgt.. Boxed for Exp't Code Space Power lbs. Wgt., lbs.

The machine is heavy and rigid in all its parts, has large base, is convenient in all adjustments, of new design and first-class in construction. Capacity: — It will cut a tenon 3 pi" at one operation and 6^4" long by passing the material through the machine twice. Any thickness of tenon may be cut on stock up to 5^4" thick and 15" wide. One set of heads and knives are furnished with each machine. Cut-off Saw attachment can be furnished at an extra price. Technical Features The Headstocks — Are both adjustable vertically by means of two screws. The top headstock has independent vertical adjustment to change thickness of tenon, and has lateral adjustment for cutting tenons with shoulders unequal distance from end of material on opposite sides. Both headstocks being adjustable in conjunction and with one screw enables the operator to center, or place, his tenon instantly. The Cope Headstocks — Are attached to the main head- stocks and are adjusted with them. Each also has independent vertical and horizontal adjustments. The Carriage — Has com- bination roller movement which greatly facilitates the work, both in ease of operation and as to quantity turned out in a given time. It is properly secured to the ways, provided with guards and cleaning device, constantly retaining a perfect alignment with the cutter heads. The top of table has longitudinal lines to which the guide may be set, for various widths of material, at perfect right angles with the cut of the heads. A pocket is provided with spiral spring to hold a marker to mark the face side of material as the carriage is passed over the ways. The hold-down device is convenient and efficient and the fence may be set to any required angle. The rolls on which the carriage travels are connected from end to end and mounted in a frame, hence the carriage must move perfectly true across the ways. This insures not only an easy movement, no matter where the operator may take hold of the carriage, or how much weight there may be on it, but also perfect work. The carriage is equipped with our Patent Bridge Bar and End Stop Gauge. This effects a large saving of time and insures accurate work. The Front or Rear Cut-Off Saw Attach- ment — Has a lever by means of which the saw may be adjusted to a graduated scale, while in motion, to cut off the tenons at any desired length. This lever is handy to the operator and results in saving much time, especially on job work. This cut-off attachment is driven by a belt running from the cope counter, which belt may be removed when the cut-off saw is not in use. The Cutter-Head Spindles — Are 1 %" diam- eter carrying pulleys 4" diameter by 4X" face, and run in side clamping boxes 4" long. The cope spindles are Pi" diameter. The Guide Pulley — On the rear of the machine which acts on the belt that drives the cope counter is a decided advantage, because it gives this belt better contact on the pulley on the vertical shaft.

There are two changes of feed, 4s" and H" per revolution of the spindle. This speed can be doubled by reversing the cones on the feed shaft. The cross line screw for moving turret has micrometer dial. Cross-Slide — Is neatly fitted and strongly gibbed to the carriage and has an extra long traverse for turn- ing duplicate parts. Turret Plate — Is graduated in degrees so that the compound rest can be instantly set to any desired angle. Counter- shaft — Is driven by self-oiling friction clutch pulleys having bronze bushings arranged to run at two different speeds by two belts; namely, 120 and 750 R.P.M., giving the head block spindle a variation in speed from 71 to 2310 R.P.M., in eight speeds.

It will H also meet the requirements of any pattern shop for a lathe with a 12" r swing. It is built with or without a movable carriage and set-over tail stock. Capacity — It is made regularly with a 55" bed which gives a maximum distance of 26" between centers. It is also made with 48" and 72" beds, American Tool Holder giving a distance between centers, 19" and 43" respectively. It is fur- nished with headstock and tailstock with swiveling features as an extra. With each machine is furnished a }4" cup center, one 6" face plate, one 3" rosette chuck for interchangeable screws, one 6" rest, one 12" rest, one blue print holder and one center drift for headblock. Technical Features Bed — Is made of cast iron, carefully planed and finished. There are no flanges on the inside to collect dust and chips. Headblock — Is nicely fitted on planed ways and secured by clamping bolts. The bearings on the belt driven lathes are ring oiling bronze bush and adjustable for wear. There are ball bearings on the motor headblock lathe. Cone Pulley is made of cast iron and is finished inside and out. The spindle is hollow and is made of high carbon steel. An end step thrust collar takes up all play. Tailblock — Is constructed so the cutting tools may be brought close to the centers without interference. Spindle is bored and reamed for centers, hav- ing a taper ]/ 2 " in twelve. Countershaft — Has self-oiling bearings, four step cone and tight and loose pulleys 6"x2K". 800 R.P.M. Motor Drive — Extra according to type. D. C. Motor Headblock — The A. W. C. Motor is a special design for use with our equipment only. Its operation is very simple, consisting of a start and stop push button station, the starting point working in connection with a magnet switch which closes the main circuit to motor. The rheostat handle must always be brought back to the minimum speed point in order to insure the motor starting on full field. The speed can then be regulated between 600 and 3000 R.P.M. by movement of the rheostat handle operating through field circuit of motor, and this provides max- imum efficiency at all speeds. It is also provided with overload circuit breaker, low voltage release and dynamic braking which brings the motor down to predetermined speed. The stop button working in connection with the low voltage release, with the dynamic feature, brings the motor to a stop. A. C. Motor Headblock — An A. C. Headblock on a Speed Lathe is an entirely new idea; and, the fact that it is new and because we originated it, we are not a little proud of it. Heretofore an A. C. Drive has been obtained by mounting the motor on a saddle underneath lathe and belting from the cone on motor to the one on the headstock. The convenience and safety of our new Motor Head- block idea over the old method will be readily apparent since the use of belts is eliminated. Motor is K H. P. 3 phase, 60 cycle and gives four speeds — 570, 1,140, 1,710, 3,420. (A 2-phase installation can be had at a slight additional cost.) The controller, like the motor, is made especially for use after our own specifications. It is mounted in the leg of the lathe and is operated by the lever shown in cut. It is totally enclosed and in the "off" position the motor is entirely disconnected from the line. Motor Underneath Head Block — This motor is K H. P. and is mounted on a saddle underneath the headblock and enclosed. To the motor shaft is attached a four-step cone pulley which is belted to the cone pulley in the headstock through an opening in the bed of the lathe. This motor may be a D. C, a single-phase A. C. motor, or again a two or three- phase A. C. motor. The illustration shows a polyphase motor, any voltage, running 1800 R.P.M. The Starting Apparatus, as shown below is an American Iron-Clad Fused Switch which is totally enclosed. 69 Figure 1064-B American 12-inch Speed Lathe With Motor Headblock and A. W. C.

The machine in recent years has undergone many minor improvements, and the product we turn out today we designate our Columbia No. 2. Quite recently we have added a new method of driving the drums; that known as our Silent Chain drive which is furnished at the option of the purchaser. See page 76. Capacity — Made regularly to open 8", but can be made to open 12" thick at an extra price. There are three rates of feed, and the machine is furnished with drums covered with sandpaper ready for use. Technical Features The Top Frame — Is supported on all four corners on posts, and rises and falls on raising screws, which have bearings on top and bot- tom. All back-lash of the screws is avoided, whereby one of the most common causes of poor work — viz., the rocking of the top frame — is overcome. All operators who have had to contend with back-lash in the raising screws will appreciate our device for over- coming this fault. The Cylinders — The most important feature of a sander, are three in number, each made in one piece, of semi-steel casting, turned, ground and balanced on especially constructed ma- chines. They are provided with our patent automatic paper tight- ener, which takes up all slack in the paper while the machine is doing its work. Tight-fitting paper is the first requisite for good work. On no other make of sander is found this automatic feature, as it is covered by our own patents, and we guarantee that in all instances it will perform just what we claim for it; namely, that the paper on the drums will be kept at an even tension at all times and at all points. The adjustment of the cylinders is regulated by hand wheels, placed together on the working side of the machine in convenient reach of the operator. The raising and lowering is accomplished by wedges, which give the cylindershaft boxes a firm support, avoiding all jump- ing as is necessarily the case when raising and lowering is accomplished by screws. For re-covering the cylinders with felt or cloth, it is not necessary to take them out of the machine, as is the case with other makes of sanders, since this operation can be performed with little trouble while the cylinders remain in their respective places in the machine. Feed — There are three speeds of feed practically in- stantaneous. The lever and segment for operating the feed are located on the left hand side of the lower front girt. The segment contains five holes — three for the different speeds of feed, and two intermediate holes for instantaneously stopping the feed. The de- vice is accessible through an opening in the front girt of machine. Power Hoist — Is provided for the top feed works, which is not only a saving in time but also in labor. Its action is prompt and per- fectly reliable. In The Oscillators — We have obtained mechanical perfection, and by our device the reciprocal movement is absolutely in the line of the axis of the cylinder, thereby avoiding any lifting or cramping motion. This is imperative to secure good work. The Boxes — For cylinder shafts, oscillators and counter-shafts are self-oiling, having oil receptacles and drain plugs; the loose pulley is also similarly arranged. Fig. Size Floor Space T. & L.

The drums are cast in one piece (not made by short sections set- screwed to the shaft), which greatly enhances the rigidity of the shaft removing from it all trembling. The Take-up frame or paper stretcher is also cast in one piece, and swings loosely on the drum shaft. Before it is inserted into the cylinder it is carefully balanced. The clamps consist of an oval steel bar fitting closely in an oval seat. One clamp is fastened to the cylinder casting, the other to the Take-up frame. They are actuated by eccentric clamp shafts. Turning these in one direction closes them, and turning them in the opposite direction opens them. The clamp shafts press on a series of flat springs in order to accom- modate different thickness of paper at the same time, furnishing an excess of pressure. The paper being held in oval seats with the aforesaid excess of pressure can never pull out. The Take-up is held back by a series of eccentrics while the paper is being put on the drum. As soon as these are released the coil springs come into action pushing it towards the other side of the open slot. As it is mounted on the central shaft and moves on the line of the circumference, any slack of paper that may occur will instantaneously be taken up as it appears. To put the paper on the Columbia drum is the simplest kind of a job and requires but a moment. Place one end of the paper into the set of clamps on the strike side of the drum and close the clamps; then revolve the drum until the other set of clamps appear; insert the other end of the paper into the remaining set of clamps and close them. This done, release the eccentric, and the work is finished. If it should become necessary to re-cover the drums with felt or canvas the operation is easy and consumes but little time. There is a half-round strip of steel under which is fastened the felt on the strike side of the drum. The other end is simply tucked in and held by the take-up. When it is remembered that there are sanders on which the drums have to be taken from the machine before they can be re-covered, this is no small item in favor of the Columbia. 77 Wedge Block Adjustment of Drums THIS illustration is a broken out view of the wedge block adjust- ment as applied to the Columbia Sander. By the use of the wedge block we have an absolutely rigid support that will not wear, as is the case where the drums rest on screws. Hence, no lost motion can occur to disturb the parallelism of the drums. A, represents the drum box stem which fits closely into a reamed hole in the frame. Across this stem is planed deeply a diagonal slot which the wedge block, B, engages. This wedge block slides in a sub- stantial housing in the frame — represented by C. The wedge blocks on both sides are connected and adjusted by hand wheels at the front of machine. A careful study of the illustration will clearly show the rigidity that must obtain with this construction, and the superiority over raising screws must be readily apparent. If it should become necessary to adjust these wedges for an align- ment of the drums (which is most unlikely) provision is made for that, and it is simple — requiring nothing but the turning of a screw in the block itself. A Perfectly Central and Non- Cramping Oscillator THE oscillator is the most deli- m cate piece of mechanism in the construction of a sander and the most difficult in which to over- come wear and lost motion. As implied in the title, its action must be perfectly central and there must be no cramping. In other words, there must be no pulling up and down. The flexible joints together with the eccentric and strap illustrated here insure an absolutely central oscillation. Means for the perfect circulation of oil is an essential feature of the Columbia oscillator, as well as of the drum shaft bearings, and is clearly shown in the illustration. Provision is made for taking up lost motion in the oscillator bearings as shown by the reversed collar on the end of the drum shaft which is filled with fibre washers. Babbitted washers are located between the collars and the oscillator boxes to prevent any wear there. 78 -0- ^T 4> //A k '( K il 1 * 4 1 UJJ u_u £" alundum cone for wet grinding. It has an attachment for grinding flat hand-plane bits. Oil stones can be used in place of the alundum wheels, but the latter are preferable because they will not gum up easily and do not have to be frequently dressed off on that account. Two alundum wheels 12"x2" and one alundum cone 5"x3J^" are furnished when required. Hole in wheels \%" diameter. Technical Features Frame — Is a one-piece casting with broad foot flange and stands free from vibration when the wheels are kept in balance. Arbor — Is fitted with a two-step cone pulley, giving two speeds for different size of wheels. The driving cone and belt are enclosed in the machine The arbor bearings are of good length and are self-oiling. Water tanks are located under each wheel and are adjustable vertically by foot treaders at the base of machine. Motor Drive — When motor drive is required (as shown in the cut) the base of the machine is extended to receive the motor which takes the place of the tight and loose pulleys, being connected direct to the lower cone shaft. Countershaft — (When furnished) has T. & L. (self-oiling loose) pulleys, 8"x3^" and should make 1100 R.P.M. for the alundum wheels, or 550 R.P.M. for oil stone wheels.

The frame is of pedestal form, cast in one piece, and it supports the carriage ways, the adjustable head stock carrying the grinding wheel arbor and all the operative parts of the machine. Capacity — Made in two sizes, 31" and 37". Technical Features The Carriage — Moves on gibbed ways by means of a rack and gear- ing and is extra heavy and rigid. Stops are provided for changing the stroke which can be adjusted when in motion. The actual extreme reciprocation of the carriage is about 3" more than the rated capacity of the machine, so that the wheel clears the knife at both ends while reversing. The Grinding Headstock — Is gibbed down to ways planned at right angles to the carriage ways, and the arbor bearings are of the side clamping type, making adjustment easy and accurate. A. cross- feed screw is provided to adjust the wheel to the work auto- matically as the carriage reciprocates, and it has a hand wheel con- venient to the operator, for independent adjustments. The Feed — Is entirely automatic, the reciprocation of the carriage being con- tinuous, and the forward feed of the grinding wheel is capable of adjustment from 1-1000" to 1-3000" to each reciprocation. This movement is controlled by a stop which can be set so that the wheel will cease grinding at any point, and by means of the vertical hand lever, the reciprocation of the carriage can be varied or stopped at any point. The Patent Knife Bar — Is a new departure in machines of this class and enables the operator to grind ordinary slotted knives in the usual way, and also provides a clamping jaw to hold thin hard steel knives, which may be firmly held and ground without a separate attachment to the bar. By a special device, thin knives can be brought up to the wheel at an angle adapted to the work to be done, and they may be back ground without shifting in the clamp; there is also a special duplex index disk on the end of the bar graduated so that the approximate grinding angle may be found quickly and the exact angle afterward determined by the differential position of the two sets of graduations; this device also provides for the changing diameter of the grinding wheel so that the grinding angle may always be deter- mined accurately. Patent Back Stops — Are attached to both the slotted knife face and the thin knife clamp, whereby the edge being ground will be kept parallel with the back, and the knife thus always balanced. There are many other important details, which render this machine superior to any now made. The Grinding Wheel — Is 26" diameter, and cased, and provided with a water nozzle and return spout so that all emery and steel dust is carried to a settling tank with the water. A rotary pump supplies a large volume of water. A Countershaft — -Is supplied in the base of the machine, having 10"x4" T. & L. (self-oiling loose) pulleys, which should run 300 R.P.M. There is a hand lever shifter for the main driving belt attached to the machine frame. Fig. Size Floor Space Horse- power Weight, lbs. Boxed for Exp't. Code Wt., lbs.

The frame is of pedestal form, carrying two planed ways on which the carriage slides. The solidity of this construction insures per- fect grinding. Capacity— Made in four sizes, 30", 36", 42" and 50". Technical Features The Knife Bar — Is so shaped that the grinding may be performed either to or from the edge of the knife and a screw adjustment is pro- vided for setting the knife at any desired angle. The frame carrying the knife bar is pivoted to the carriage so that the bar may be swung away from the wheel to provide easy access to the knives when changing. The Feed — Is entirely automatic; the reciprocating movement of the knife carriage is governed by stops so that any length of knife up to the capacity of the machine may be ground. The movement of the wheel to the knife can be regulated to grind from 1-3000" to 1-1000" to each back and-forth movement of the knife carriage. The movement of the wheel carriage when set is automatically controlled and the wheel will cease grinding at any point desired. We furnish one emery wheel 26" diameter, IK" face. A Pump Attachment — And tank are supplied for use when wet grinding is desired. The tank can easily be removed for cleaning when necessary. If desired the pump and tank can be omitted and an overhanging tank supplied at a slight reduction in price. Counter- shaft — Has T. & L. (self-oiling loose) pulleys, 12"x3"; speed, 300 R.P.M.

We were the first in the field to apply motors to our machines and the develop- ment of successful drives has been largely due to us. The following pages specify the various types of drive for the machines illustrated in the catalog. The success of an electric drive depends very largely on the type of control used in connection with it. We illus- trate the various types applied to our machines on pages 90 to 96. Electric Control Data Control A Consists of Hand Starting Compen- sator which com- prises an oil immersed switch with sliding contacts, low voltage protection and overload relays. It is used with all squirrel cage motors, 73^2 H. P. and over. 90 Electric Control Data — Continued Control B Consists of an oil immersed starter and is designed for starting small motors — 5 H. P. and under, and is used pre- ferably on 440-550 volts, to take up dangerous arcing. i m m .... . , :■ Control C Consists of a 3 or 4 pole single throw, quick make and break switch, two protective plugs, two hinged covers, one over-switch and one over-plug. The switch is designed so it is impossible to open unless switch is off. Overload is obtained by two time limit plugs which take care of mo- mentary overload in starting. It is impos- sible to single phase a motor with this switch. This switch is used in connection with all motors up to 5 H. P. 91 Electric Control Data — Continued Control D Consists of a three pole snap switch mounted on porce- lain base with fuses and enclosed in a Crouse-Hinds special condulet. It is used only on 2 H. P., 3 phase motors and under. Control E Is used for direct current only and consists of a two- pole fused switch for over- load and a standard rheostat with low voltage protection enclosed in metal case, mak- ing a totally enclosed unit ; it is used in connection with all D. C. motors. 92 Electric Control Data — Continued Control F Consists of two-point contactors, magnetic blowout for low voltage and fused switch for overload protection; is used on all D. button control. C. motors up to 7/2 H. P. with push Control G Consists of standard, open rheostat for all D. C. motors and does not in- clude any switch. Control H Consists of a standard enclosed fused switch, two or three phase, used on all motors up to 5 H. P. in place of time limit if desired. Control J Enclosed fused starter. Its motion is automatic in that the first movement throws the motor directly on the line and holding same for a few mo- ments, then releasing it, auto- matically cuts off the line and throws the fuses in running. For all A. C. motors up to 5 H. P. 93 Electric Control Data — Continued Control M Is used on single phase motors, and is included in price on all 7A H. P. and over. This control cuts down the starting current from 2 l A to 3A times, running to VA, and allows the motor to come up slower Control N Is an automatic A. C. push button type for A. C. motors up to 73^2 H. P. 94 Electric Control Data — Continued Control P Is a 2 or 3 phase snap switch for A. C. motors, 2 H. P. and under. Control R Is an automatic compen- sator with overload relays, triple pole contactors mounted on slate base and one start and stop push button station; it can be used on all A. C. motors. Control V Is a special control for A. C. Motor Head Blocks as applied to lathes. 95 Electric Control Data — Continued Control W Is a special control for use on D. C. Speed Lathe only, con- sists of a push button type over- load, low voltage and dynamo brake. Control Y Consists of a totally en- closed dust proof oil switch with overload and low voltage protection. .!7:J 96 Electric Starting Apparatus (Illustrated pages 90 to 96) Controls Electric Current A Hand- Starting Compensator Sin. -Ph. 60 Cy. llOv.

Sufficient examples are given to enable the student to arrive at a fair under- standing of what is the correct position to take at some of the principal machines he will be called upon to operate. The Lathe, the Universal Saw, the Jointer and the Sander and their operation form the chief source of experimental training in the woodwork- ing department of the manual training school. Consequently we have confined our illustrations to these machines. 103 FRONT ELEVATI0M Of AMOUCAN SPEED LATHE MOTCM DTtlVCN Front Elevation of Motor Hcadblock Lathe (American 12-Inch Speed Lathe) On Operating the Lathe The Lathe is perhaps more closely akin to the art side of the student's development than any other wood- working' machine. And, for that reason, it claims his highest interest. With it his skill in forming articles of use or beauty is challenged; for what he accomplishes depends almost entirely upon himself. That is what makes the Lathe so interesting and so essential to the equipment of the woodworking department of a voca- tional school. The process of turning will always form the centre of interest in such a department. \M The Roughing Cut In this illustration the student is preparing to take the roughing cut in turning a cylinder. This operation consists in removing the corners of the square piece and is done with the tool known as the gouge. m The Sizing Cut After the roughing cut has been taken calipers set to the diameter desired will determine the depth of the next cut. The illustration shows the student performing this operation with the cut-off tool. 10* The Paring Cut When the correct dimension has been found, as shown in the preceding illustration, the next step in the process of turning a cylinder is the paring cut or finishing cut. This is done with the skew or bevel chisel. A very thin shaving is removed by this operation, 10? Cutting the Ends This operation is performed by using the cut-off tool. It is merely taking a slice off the end. If a very thin slice is to be removed, it is usually made by the long point of the skew chisel. If it is more than a quarter of an inch it should be sized and then removed by the skew. 108 Rounding If it is desired to round the end of a piece or to pro- duce a convex surface the operation can be done by apply- ing the broad side of the skew chisel. This is perhaps the most difficult operation to perform if accuracy is obtained. iw Polishing This operation is done with a cloth after the cylinder has been sanded and while rotating in the lathe. In sand- ing, use first a fairly coarse grade of paper, No. 1 or 1J^, and afterwards a fine grade, No. or 00. Before applying the cloth the wood may be varnished lightly while the lathe is not running, taking care to wipe off all the surplus varnish. The varnish will assist in giving the surface a fine polish when the cloth is applied. no Face Plate Turning The preceding illustrations show the process of turn- ing when the piece is supported between the live and dead centers. The process shown in the next three pictures illustrate the character of the work done with the head stock only when the piece is supported by the screw- centre chuck or face plate. The Scraping Gut This cut is properly made with the concave chisel held in such a position as to give a light scraping cut. Care should be exercised not to allow the chisel to extend too deeply, otherwise the material will chip with the grain. After the desired circumference has been obtained the surface should be smoothed with the skew chisel. in Modeling a Rosette This illustration shows the student using the rest, set at right angles with the bed or parallel with the face plate. Prior to the modeling a shearing cut should be taken with the skew chisel to face off the material to an even surface. 112 Use of the Dividers This illustration shows the use of the dividers. The student is marking off to a uniform scale the position of the various corrugations in the rosette he is turning. 113 Cutting off to Gauge with Rolling Table Roughing out a Core box with use of Ripping Gauge 114 srcctt sr*t+ven 44J0/A& Z4Bi£ iOCX Front Elevation of Universal Saw (American No. 20 Universal Saw) On Operating the Universal Saw The operations that can be performed on the Uni- versal Saw are so many that we shall not attempt to illustrate them all here. But enough are given to show the characteristic poses involved in cross-cutting, ripping, and dadoing, — the three basic uses of a Universal Saw. It is a more dangerous tool than the lathe and the guard should be kept over the saw at all times, except of course, in dadoing when it cannot be used. 115 Cutting off with Sliding Gauges Making use of Dado Head 116 • Using Pulley Segment Gauge Panels made on the Universal Saw Bench with aid of the Protractor 117 Use of Patent Bevel Protractor as Applied to American Universal Saw Bench The drawing shows a brace extending from a point 2" in one direction and 4" in another at right angles, the object being to determine angles, A B and C. The Starting Point of fence is 45 degrees or common mitre. In setting fence for the measurement, viz., 2"x4", the operator starts at 2" on the Cross Graduated Sector and then follows the 2" line, which parallels the travel of the saw until he reaches the 4" line. The intersection is marked with a star in drawing. Angles'. — You will note that you are dividing an imaginary block 2" wide by 4* long. The fence, when set, registers an arbitrary graduation in circular arc 2j4" . This gives you the acute or steep angle A. This setting also gives you the key to all angles that it may be desired to cut, and it is only necessary to remember the one point, viz., 2}4". To determine angle B, set fence 2^4" to the left of the 45 degree line. To determine angle C, start at 90 degrees and carry the fence forward two lines 2j4" > viz., 5*. 118 Front Elevation of Hand Jointer ( American No. 1 ) On Operating the Hand Jointer The great variety of work that can be done on a hand jointer depends very largely upon the knowledge and skill of the operator. In this fact lies the value of this tool as a part of a school equipment, — second only to the lathe. It lends itself to so many operations, that the student gains much in knowledge and efficiency. The five operations following, will give a fair idea of the scope of work that is usually accomplished on a hand jointer and show something of the method by which the work should be done. The Jointer is another tool when the use of the guard should never be omitted. 119 Planing out of Wind Removing corners or chamfering Making Glue Joints Rabbeting Planing a Bevel for Mitre Work 122 On Operating the Sander The Sander is an interesting machine in the school room for on it considerable "forming" can be done as with the lathe, although its prime use is to make smooth or polish. In the single illustration following, the boy at the left is forming a mitre while the one at the right is smooth- ing a surface. 123 Part III A literary education is no education. All the classics of the past cannot make men. Experience does, life does. — Leonardo da Vinci Machine Specifications for the Cabinet Shop IN order to assist school men charged with the responsibility of writing the machinery specifications for cabinet shop equipment, we append the following pages. Any of these may be copied literally with the assurance that every important item that should enter into the construction of a high grade machine is covered completely. Of course we have used our machines as the basis for these specifications; but they will cover any other make of high grade woodworking machines as well. They are intended as a protection against the substitution of machines inferior to ours which are known and accepted in the industries as the standard. The subject Alternative Specifications given after each machine refers generally to other ways in which certain parts of American machines may be constructed and particularly to the latest methods of motor drive. 127 Specifications for Woodworking Machines 36-Inch Band Saw (Illustrated page 8) Capacity — To take 18" under guide at its highest point and 36" horizontally.
