This company has always been averse to the idea of superficiality and mere cheapness and has won a most enviable reputation as pro¬ ducers of the “best that’s made”, thereby building up a business of tremendous magnitude on the sure, substantial foundation of Merit. Years of experience, carefully compiled records of experiments and results, and a vast collection of other valuable information are always freely available to screen users in all parts of the world. The object of this book is two-fold: First, to advertise and thereby create an even greater demand for the Ludlow-Saylor products; second, as an educational work that shall provide information of almost incalculable value to those in charge of industries where screens are used, proving that Ludlow-Saylor screens are not mere woven wire, but that each and every kind is made for a distinct, definite purpose and according to methods that have been perfected by years and years of careful investigation and experiment. Every known condition under which screens may be used has been thoroughly studied with a view towards making a screen for every conceivable purpose that shall exactly fulfill every requirement. If this book proves of interest and value to those to whom it is sent, its purpose will have been amply achieved. Sincerely, THE LUDLOW-SAYLOR WIRE CO. LUDLOW - SAYLOR WIRE CO. ST. LOUIS.U.S.A. Gauge Numbers and Decimals The Ludlow-Saylor Standard Decimal Sizes for Wire of all Metals Steel Wire Gauge or Washburn and Moen ■ We use decimal numbers to denote wire diameter, but for the benefit of those still accustomed to the old gauge numbers we will, throughout this entire book, use both systems. On the opposite page we show the relative variance in size as shown by several different gauge tables that are used most com¬ monly. You will notice that, while the number of two wires, under the old system, may be the same, yet the actual size, as expressed more accurately in decimal fractions of an inch, will vary somewhat under the different tables. For this rea¬ son it has been found advisable to always give actual decimal measurements, thus precluding the possibility of error in filling orders. When both the gauge number and standard are known, it will be possible to determine the actual size of the wire by referring to these tables. There is, therefore, but one safe and sure method to pursue in ordering—never forget to give the size wanted in decimal fractions of an inch—use the num¬ bers if you care to do so but give the decimal measurements also.

S,U.S.A. Tj&fcclC Double Crimped Wire Cloth "thousands of satisfied users, in all parts of the United States and in many foreign countries, testify to the superiority of the Ludlow- Saylor “Perfect” double crimped wire cloth—and they give their testi¬ mony in a fashion that admits of no argument—by re-orders. Seldom indeed does a man of discernment and practical experience ever again use any other make of screen after having once used the “Perfect.” The reason for this lies in the care with which the wires are made, the way they are woven and the clever crimped feature. In the weaving of the “Perfect” double crimped wire cloth, each wire supports and strengthens every other wire, the shoot wires being arched over and under the warp wires, and the warp wires arched over and under the shoot wires, thus forming a mesh that is absolutely and permanently rigid, eliminating all possibility of wires slipping and insuring an evenness of the screened product. And the wires are not bent but crimped —not with sharp angles, but curved gradually and gracefully over and under the intersecting wires, without any rough corners. Thus the full strength of each wire is retained and its surface kept smooth and unbroken. All strain is equally distributed over the entire screen, and the openings remain uniform and equal as long as there remains enough metal to sustain the weight of the material to be screened. The initial cost of the “Perfect” screen is perhaps a trifle more than that of the commonplace, ordinary, non-durable kinds, but its lasting powers more than counterbalance the slight additional initial cost and make it eventually by far the cheapest to buy. Ii Illustrating the “Double Crimped” Feature as found in All Ludlow-Saylor Screens Note the Uniform Crimp in the Two Shaded Wires in Above Cut Also the firm rigidity of the entire weave, obtained by the double crimping of both warp and shoot wires, making it absolutely impossible for any single wire to shift, thereby insuring the permanency of the mesh and uniform even wear throughout the entire life of the screen. 4 Mesh, No. 12 .105 Wire 17 leaj LUDLOW-SAYLOR WIRE CO.

U S.A. r Steel Wire Cloth Beginning with this page, tables are shown which give the mesh, number of wire, diameter of wire, size of opening between the wires, and list price per square foot. This and the following pages refer to steel wire cloth, and prac¬ tically every grade of steel wire cloth is covered in the tables. In case the screen you need is not contained in the tables, we shall be glad to supply same ac¬ cording to any specifications, as we are in a position to manufac¬ ture any mesh or diameter of wire that can be produced of steel wire. The illustrations of the various screens on the following pages, while not mathematically exact in every detail, are as accurate repre¬ sentations of the mesh, size of opening and diameter of wire of the different grades, as it is pos¬ sible to reproduce in print. In so far as the eye and the table can determine, this will probably be of some assistance to you in arriving at a near con¬ clusion as to what particular screen you can use. The perfect double crimped steel wire is constructed by machines of the latest invention which pro¬ duce absolute accuracy. The wires in both warp and shoot are thoroughly and evenly crimped; this makes a perfect mesh that retains its uniformity until the screen is practically worn out.

Don’t forget the following: Number of Rolls, Number of Pieces, Length and width of each piece or roll, Mesh, Decimal size of wire, Material from which cloth is to be made. No order is complete without the above. The mesh is not sufficient with¬ out the size of wire being given also. As an example, look at the number of 3 meshes in the table; there is a variation of almost 100 per cent in the size of the opening. The size of wire and mesh are absolutely necessary. A full roll contains 100 lineal feet or more. Less than 100 lineal feet in¬ voiced at broken roll prices. Widths carried in stock are: 24, 30, 36, and 48 inches. Special widths, to the fractional part of an inch, made to order. In ordering screens, send a small sample of wire cloth with quantity wanted; otherwise be sure to spec¬ ify width, mesh, diameter of wire and amount of material. We cannot dispose of specially made screens; therefore be sure your specifications are absolutely correct. In repeat orders, refer to original order or date of invoice and re¬ quest that it be duplicated. Number of Meshes per Inch Number of Wire Diameter of Wire.

ST.LOUIS.U S.A. l=s Screen Durability The weaving of wire cloth is in itself largely mechanical, but the selection of the material to be used in the manufacture of wire cloth for any special service is of vital importance and should be given the utmost care and consid¬ eration. The Ludlow - Saylor Company have given much thought and study to this subject, and are con¬ stantly experimenting with new and varied kinds of wire with the sole object in view of improving the quality of our products where- ever and whenever we find it possible to do so which is the secret of the long life of our screens. The “Perfect” double crimped cloth is made so that the wires are uniformly crimped both in the warp and shoot and are of the same height throughout. Therefore there is an even wear¬ ing surface in which one wire does not wear out quicker than the other. This double crimped feature makes both wires perfectly sta¬ tionary and impossible to shift and causes accuracy in screening until the screen is worn out. A greater variety of sizes and materials in this style of screen are being constantly added to stock owing to an increasing de¬ mand as the new uses to which it can be put manifest themselves.

StouVAtCutiNDi J Size of Opening By openings, we mean distance between the wires—the open or vacant air spaces. It is possible to have many different screens measuring the same number of meshes to the inch, but each with a different size of opening due to the fact that the wires are of different diameters — the thicker the wires the smaller the spaces between them. The size of the opening is lessened by using heavy wire and increased when lighter wire is used. Thus, if a 6 mesh screen is made from .080 wire, the opening is .087 inches but if we decrease the diameter of the wire to .023, the opening is thereby increased to .144 inches. In other words, if the number of openings to the inch is decreased the diameter of the wire must be increased to maintain the same size opening. On the other hand, as the number of openings to the inch increase, the wire diameter must necessarily be decreased to keep the openings the same size.

J IreKTANGb Iron or Steel Wire Cloth Continued IL Screens for Mining Owing to the unusual amount of wear and tear to which a mining screen is put, the wire cloth must be of a construction and quality to meet this demand. No screen has been found better for the purpose than the Ludlow-Saylor “Perfect” double crimped wire cloth. This has been proven by actual usage and experience. The “Perfect” screen has withstood the severest tests with most satis¬ factory results. This screen will give service until the wire is worn too thin to retain the weight of material being screened. This unusual feature is due to the double crimping which keeps the wires in their original position until worn through. It is the ideal screen for hard service in mills and mining indus¬ tries, and for use on jigs, trom¬ mels, stamp batteries, Chilians or shaking screens. The Ludlow-Saylor screen is made of iron, brass, copper, steel or, where acid comes in contact with the screen, a phosphor bronze is recommended.

I Quality is Our Slogan Quality in material, quality in workmanship and quality in the finished product — And quality means efficiency in screens. The Ludlow-Saylor plant has grown as the demand for its prod¬ uct has increased and this growth is due entirely to the superiority of the Ludlow-Saylor screens. Experience has proven that the better and higher priced screen is more economical than that screen where first cost only is considered. A screen must be right to speci¬ fications or a loss and unevenness in product will result. The Ludlow- Saylor screens prevent this loss because they are right. The mesh counts the same both in the warp and the shoot and is made absolutely correct as to gauge specified. The frequent changing of screens necessitates additional labor; also loss of motion and any loss of motion decreases the output. The proper way to figure the ultimate cost of the Ludlow-Saylor screens is by the number of tons of ore it will screen before wearing out, compared with the life and producing power of the less expen¬ sive screens made by other manu¬ facturers.

Therefore in the milling of ores, the screens that will produce the greatest tonnage of product to the desired size per stamp are the most profitable: That is, provided the screen is accurate and no after treatment is required to produce an even screening. The Ludlow-Saylor screens are accurate, not only the same num¬ ber of meshes both ways but the same gauge of wire and same size of openings throughout. This means an even screening and big returns. Therefore, the Ludlow - Saylor screen is more economical than the perforated metal screen which does not yield an equal tonnage and evenness of product. An uneven product requires an after treat¬ ment which adds to the cost of production. Wherever perforated metal is used, the openings become larger with wear and the screening in¬ creases in size. The Ludlow-Saylor screens can be supplied with either square or oblong openings which remain the same throughout the entire life of the screen.

Cement of this character has the highest efficiency, and is produced by the Ludlow-Saylor “Perfect” screens. For this reason cement indus¬ tries all over the country have in¬ stalled “Perfect” screens. They give accurate results, and accurate results can only be produced from accurate screens. By accurate screens is meant not only that the mesh counts the same both ways, but that the wire gauge is exact and that the openings between the wires are the same to the thousandth part of an inch. There are cheaper screens than The “Perfect” to be had, but the saving on first cost is more than offset by the short life of these lower priced products and by the vexatious delays caused by their uneven wear. In the long run the “Perfect” double crimped screens save the purchaser money, time and trouble. Cement Screens are kept in stock in all regular widths and sizes of wire for ordinary require¬ ments. Screens to special specifications made up quickly and accurately.

L Ji 36 In addition to the regular grades of Steel, Brass, Copper and Bronze Wire Cloth listed in this Catalogue, The Ludlow-Saylor Company is prepared to fill any specifications for wire cloth from any of the metals in commercial use such as Monel, Nickel, Aluminum and American Ingot Iron. Monel Metal is a white alloy, a natural combination of 67% nickel, 28% copper and 5% other metals, chiefly iron and manganese. It is strong as steel and withstands acids, alkalies and high temper¬ atures, and is used largely in the manufacture of filter cloth. Nickel Wire is about 99% pure Nickel and will resist the corrosive action of most acids with the ex¬ ception of Nitric acid. It can be used to the best advantage where screens are subjected to the influ¬ ence of hot gasses or high tempera¬ tures. Aluminum wire has a tensile strength of from 20 to 35,000 lbs. per square inch. Its weight is about one-third that of copper, brass or iron. Its lightness and resistance to corrosion are its out¬ standing features. American Ingot Iron is the purest commercial iron obtainable and its rust-resisting properties are far superior to the ordinary iron or steel wires.

ST. LOUIS, U.S.A. Rolled Square Mesh Screens It was formerly necessary, in order to get a perfectly flat screening surface, to use perforated sheet metal. Naturally, the holes weakened the sheet and, if punched very close, the life of the screen was of short duration. Nowadays, this type of screen is fast becoming obsolete as it will not do the work as quickly or as accurately as the rolled wire screen. The Ludlow-Saylor double crimped rolled cloth has an efficiency of liom io to 50 per cent greater than that of the perforated sheet metal, because of the greater area of open space. In addition to doing work fastei the rolled cloth will yield a uniform size of product throughout its entire existence; whereas, with the perforated sheets, the product gradually becomes coarser and more uneven as the holes wear larger and larger. Rolled Brass Screens The “Perfect” double crimped rolled wire cloth is particularly desirable wherever a flat surface is advantageous in screening or where a coarse mesh is necessary to support a finer one. This rolled wire cloth can be furnished in any metal, cut in pieces of the exact size to fit the frames. Rolled cloth, having the same sized screen as perforated metal, possesses a much larger discharging area and hence produces a greater output. Then, too, the drawing process imparts a hard, smooth finish to the wire that will not wear away or become rough. Galvanized Wire Screen In order to be sure the coating is thorough and perfect, the Ludlow- Saylor Company operate their own galvanizing plant in making the “Perfect” galvanized wire cloth. Galvanized-before-woven cloth is made from the best grade of galvanized wire, is specially adapted for many purposes, and can be supplied in all the different meshes and sizes of wire shown in our price list of steel wire cloth up to and including thirty mesh. Our galvanized-after-woven cloth is made from the best steel wire, which is uniformly crimped both ways; it is then thoroughly coated with pure spelter, which solders each joint and makes the cloth rigid and rust-proof. We are prepared to galvanize cloth after it is woven in all meshes up to and including 8 mesh, and in all widths up to and including 48 inch. Anything finer than 8 mesh must be woven from galvanized wire, as it cannot be put through the spelter bath without the openings becoming clogged. Where dampness is prevalent or there is any danger of rusting, galvanized cloth should be used in preference to the steel or iron cloth. When coarse meshed screens are made from light wire, it is better to galvanize the cloth after weaving, thereby holding the wires more firmly in position. f RFX IWtl- ■BBZjuiaBwiflJ Examples of Wire Cloth, Galvanized After it has been Woven ■nn 2 Mesh, No. 12 .105 Wire 3 Mesh, No. 14 .080 Wire 4 Mesh, No. 16 .063 Wire 4 Mesh, No. 18 .047 Wire IR33S. |w dqp Lib o 1 | J LUDLOW - SAYLOR WIRE CO.

The tables show the size of opening, number of wire, diameter of wire and list price per square foot in heavy coarse steel screens from 3/16 inch opening to 4 inches. These heavy screens are supplied in sections of exact length and width to which there is no limit, except as to convenient size for handling and shipping. If so desired, screens can be rolled to any diameter for trommel or revolving screens. No better screens are made than theLudlow-Saylor screens for grad¬ ing coal, crushed rock, stone, sand and gravel into various market¬ able sizes. It is the screen in general use in mining districts on trommel screens. It works with better results than the perforated steel plate, and owing to quality of special material and construc¬ tion will outwear any screen made.

For Coal, Gravel or Sand The Perfect Double Crimped Heavy Wire Screen, Iron or Steel Continued Screen TL When ordering screens with large openings and heavy wires, specify the size of the opening and wire, as “3^ inch opening,” “3/16 inch wire,” or specify wire in decimals, as inch opening, .135 wire.” Because the screens are larger, they are made none the less accu¬ rate, both in mesh and wire gauge. The double crimping holds the wires in the original position securely during the entire life of the screen. As the wear is on the surface of the rods, the screen will screen accurately until worn through and too weak to hold the weight of the material being sized. This is one of many reasons why the double crimped screen is supe¬ rior to the perforated metal.

SCBEEN | THE PERFECT DOUBLE CRIMPED BRASS, COPPER OR BRONZE WIRE CLOTH FOR MINING AND OTHER PURPOSES “'^c^ec^'g, w ±£!5i g ±j±ri LUDLOW-SAYLOR WIRE CO. ST. LOUIS.U.S.A. Brass, Bronze and Copper Cloth These cloths should be used in sizing materials that are wet or where work is done in damp locali¬ ties where rust or corrosion are liable to affect the screens and interfere with the work. Also in mine screening or any other where the water is contaminated by acids and comes in contact with the cloth. If your screen becomes useless from rust or corrosion before it wears out it will be found advan¬ tageous to pay the additional cost of these metals over that of iron or steel. Practically every grade is in¬ cluded in these tables but any mesh or size of wire desired, that is not found here, can be furnished in short order. In ordering, please state number of rolls or pieces wanted, length, width, mesh, num¬ ber, and decimal size of wire. Also as to whether brass, copper, or bronze is desired. When writing for prices on this grade of cloth, it would be well to bear in mind that all of our quota¬ tions are based on furnishing cloth made from wire of the highest quality, as we use only the best low brass, phosphor bronze and pure copper wire in the manu¬ facture of these goods.

Galvanized Screens for Refrigerator Cars When used in Refrigerator cars, wire cloth is constantly exposed to moisture and its permanency depends largely upon its careful construction and even more upon the thoroughness with which is has been galvanized. Naturally the rust is most apt to affect wire cloth where the wires cross. The steel wire cloth made by The Ludlow-Saylor Co. for use in refrigerator cars has both the warp and shoot wires crimped both over and under and is coated heavily with pure spelter after being woven. This coating not only covers the wires but also solders the intersections, so that the entire surface is impervious to moisture and hence rust-proof. Only the coarser meshes (up to and including 8 mesh) can be galvanized after weaving. The finer meshes must be woven from wire already galvanized because the smaller openings are apt to fill up when subjected to the spelter bath. Galvanized Hardware Cloth Standard Hardware Grade Our cloth is made of the best wire, thoroughly galvanized after it is woven, which solders the joints and prevents the spreading of the wires. This cloth is used extensively for fire-proofing in place of wood lath, as the mortar passes freely through the meshes and forms solidly on both sides, thus making it practically fire and water proof. It is also used by fruit evaporators; in cotton gins; also for belts in drying machines of all kinds. This cloth is also used very extensively for lining corn cribs for protection against rats and field mice. We also make all grades of cloth in the coarser meshes, galvanized after woven, and will be pleased to quote special prices upon receipt of specifications. I 65 w iy-m » ±m± LUDLOW - SAYLOR WIRE CO. ST. LOUIS. U S.A. 1 66 Rek-Tang” Rolled Slot Screens The Rek-Tang rolled slot screen replaces the perforated metal sheet and the square mesh wire screen. We do not know of any instance where a perforated metal screen or a square mesh screen is used that a Rek-Tang screen could not be substituted with the triple advantage of greater capacity, greater uniformity of sizing and economy. Let us take these points up one at a time and find the reasons. The greater capacity of Rek-Tang is apparent when you look at the illustrations on the opposite page. The relative discharges of the three types of screen are graphically shown and a little study of the screens themselves will make the reason plain. Compare the amount of dead space in the perforated metal and the Rek-Tang. It is no wonder that Rek-Tang does a like job in about one third the time. And here is why the Rek-Tang capacity exceeds that of the square mesh screen. By forming an oblong instead of a square mesh the dead space in each opening is lessened by the thickness of one or more shoot wires. That in the aggregate this is an element of consideration is shown by the increase of the discharge as illustrated. w tr±E LUDLOW - SAYLOR WIRE CO. ST. LOUIS. U S A.

ST. LOUIS. U. S. A. No. 207, Rek-Tang No. 143, Rek-Tang No. 85, Rek-Tang No. 72, Rek-Tang “Rek-Tang” Screens Replace Other Screens Rek-Tang will produce sizing of the greatest possible uni¬ formity—that is there will be less fines and slime. The reason for this is that there is an absolute minimum of dead space. As soon as a particle is crushed to the proper size it is discharged. Whereas in the perforated metal screen, particles already reduced to a size that will pass the opening are often recrushed because of the extensive area of dead space. This slows down out-put besides giving a product of uneven grade. The same thing happens to a lesser extent with the square mesh wire screen. Rek-Tang screens are always made to order. None are carried in stock. This is because Rek-Tang screens are always made to definitely fit the work in hand. There are over two hundred com¬ binations shown in the three charts of standard sizes on the preceding pages, while any other combination can also be furnished. 7'his screen may be had in iron, steel, brass or copper. If you have been using square mesh, give us the number of the mesh and size of wire and we will furnish its equivalent in Rek-Tang. When replacing other screens with Rek-Tang, it is advisable to send a sample of the old screen and a small portion of the screen product. If frame is of irregular shape, a plan of the template should be included. I ygg w FtH I i ±m± I LUDLOW - SAYLOR WIRE CO. ST. LOUIS. U S. A. I Rek-Tang” Screens Increase Discharge Area I he production of any reducing mills is determined by the screen— a mill will produce no faster than the screen will permit the material to pass. And material cannot pass through the metal or wire. It must pass through the air spaces. So it follows that as the dead space on the screen is lessened the production capacity of the mill is speeded up. In this respect Rek-Tang is as near the ideal as is possible—a maximum of air space and a minimum of metal dead space. A Rek-I ang screen has over a hundred percent greater discharge aiea than the equivalent screen of slotted metal. Compared to the equivalent round hole metal screen the Rek-I ang has an advantage exceeding ninety percent. And Rek-Tang exceeds even the square mesh wire screen by approximately fifty percent. Rek-Tang insures greater capacity. w rHri? LUDLOW-SAYLOR WIRE CO. ST. LOUIS, U.S.A. 1 LL Rek-Tang” Screens Wear Longer The maximum discharge area is the all important feature of a screen. But if the screen having this quality also possesses the virtue of out wearing other screens, that is indeed a wonderful combination. Just consider for a moment how the metal screen is made. A sheet of metal is punched with diagonal slots or round holes. Every hole or slot punched weakens the metal. The closer together these holes the more the metal is weakened. Exactly the opposite is true of Rek-Tang. Rek-Tang is woven wire. The size of the opening has no effect on the strength of the wire. In fact the smaller the opening the closer together are the wires and the stronger the screen. Another feature of much importance is uniformity of wear. As a metal screen wears the openings constantly become larger. It is not uncommon for these openings to double in size during the life of a metal screen. In a Rek-Tang screen practically all the wear is on the top of the wires. There is practically no change in the size of the openings throughout its period of use. As the uniformity of the product demands screen openings of a constant size, the advantage of Rek-Tang in this particular is apparent. 80 '9ev$ec\fg w S LUDLOW - SAYLOR WIRE CO. ST. LOUIS. U S.A. L LUDLOW-SAYLOR WIRE CO. ST.LOUIS.U S A. RIK-TAWC S iHH Screen II “Rek-Tang” Screens Cut Operating Costs Operating costs drop when Rek-d ang is put on the job. It is not what it costs to operate the sizing mill for a day—but how many tons are produced, d hat is where Rek-Iang lowers cost. Rek-Tang, with the greatest discharge surface, produces more tons per day. Greater capacity is only one of the three ways m which Rek-I ang cuts operating costs. As the wear is practically all on the top surface of the wires, Rek- Tang has established a record for long wear. This means a lowered replacement cost and less frequent loss of time m installing new scieens. Uniformity of product is desirable. Two features of Rek-Iang tend toward this result. The minimum of dead space prevents re¬ crushing and results in the practical elimination of slimes. And as Rek-Tang will wear almost entirely through without a perceptible change in the size of the opening the product will remain of uniform fineness. In sizing uniformity means quality. Quality means the top price of the market. I his is an indirect, never-the-less a \ er} material saving in the cost of operation. LUDLOW-SAYLOR WIRE CO. ST.LOUIS.U S A. “Rek-Tang” Screens Made to Meet Conditions We have shown in this section of our catalog a number of different Rek-Tang screens. These are shown largely to visualize the great flexibility of Rek-Tang screening. Rek-Tang can be made of any size wire with any size openings and of iron, steel, brass or copper. In practically all numbers a single shoot wire is used, but where a double shoot wire works to advantage, the screening is made in that way. It is not necessary that Rek-Tang screening be made to conform to any of the illustrations shown. Rek-Tang is not carried in stock but is in every instance made to special order. This is done so that exact specifications can be followed and a screen produced to meet any condition. , There are three pages of tables showing in inches and millimeters standard sizes of Rek-Tang in the several weights. If you are using a metal screen or square mesh screen we can give you the equivalent in a Rek-Tang screen. ml LUDLOW-SAYLOR WIRE CO. ST. LOUIS,U S A.
