SPECIFICATION forming part of Letters Patent No. 396,437, dated January 22, 1889.

Application filed November 7, 1888. Serial No. 290,185. (No model.)

To all whom it may concern-.-

Be it known that I, HERBERT SMITH, of the city and county of \Vorcester, and State of Massachusetts, have invented certain new and useful Improvements in \Yire-Drawing Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, and in which Figure 1 represents a plan view of a wiredrawing machine embodying my improvements. Fig. 9 is an end view thereof with the driving-pulleys, as well as wire reel and block, left off, looking in the direction of arrow a in Fig. 1. Fig. 3 is a side view of one end of the back of the machine looking in the direction of arrow 1) in Fig. 1. Fig. 4isa side view of one end of the front of the machine looking in the direction of arrow 0 in Fig. 1; and Figs. 5, 6, 7, and S are a front view, plan,

central longitudinal section, and central transverse section, respectively, of the die holder or support.

My invent-ion relates to improvements in wire-drawing machines having a series of dies, through which the wire is drawn and reduced several sizes by a continuous operation; and it consists in the construction, arrangement, and combination of parts hereinafter specified, whereby the above result is effected, the essential feature being to produce a machine which shall run smoothly with theleast possible vibratory motions, as and for the purpose hereinafter more fully set forth.

Following is a detailed description of my said invention with reference to the accompanying drawings, enabling others to fully understand the nature and purpose thereof.

The various parts marked A represent the main frame-work of the machine, made in practice of the proper shape to support the various operating parts.

B is the main driving-shaf t, fitted to turn in suitable bearings, 13 B,in frame A, and having at one end the fast and loose pulleys O C, which may in practice be connected, as usual, with any suitable driving mechanism. Upon said main shaft B are mounted a series of friction-disks, Dfive in this instance whose hubs D engage with the upper ends of clutch-levers E, arranged in this instance under each hub. The lower ends of said clutchlevers are fitted over horizontal longitudinal threaded shafts F, one for each clutch-lever, and fitted to turn in suitable stationarybearin gs, F F. Said threaded shafts are held against longitudinal movement in their bearings, and are turned by means of a handwheel, G, on the end of each shaft.

The disks D are fitted to slide longitudinally on the shaft B, but are held against rotary motion thereon by means of the featherkey (I, which is preferably extended the whole length of the shaft between its bearings. Said disks D- engage with a series of disks, H, arranged at right angles to and upon a line horizontally therewith. The latter disks, II, are mounted on the outer ends of a series of horizontal shafts, I, arranged at right angles to.

the shaft B and fitted to turn in suitable sta tionary bearings, I I, in frame A. Upon said shafts I, between the side frames, A A of frame A, are mounted the friction-cones J, and above said friction-cones are mounted, on shafts K, similar friction-cones, L, the cones being arranged in a seriesof pairs in line horizontally lengthwise of the machine, with the cones of each pair beveled in opposite directions, as is illustrated in Figs. 1 and 2, and at sufficient distance apart to admit a frictionbelt, M, between them, the purpose of thus interposing the belts M between the cones being to admit of imparting a varying speed from the bottom to the upper cone of each pair by moving the belts longitudinally from one point to another on the peripheries of said cones. Said operation may be performed by means of any suitable and convenient shipping device. In this instance said result is effected in the following manner: Between the cones of each pair, at one side and parallel to the axes thereof, is arranged a transverse threaded rod, e, fitted to turn in suitable bearings at each end in frame A, but held against longitudinal movement therein. Each of said rods is provided with a handwheel, f, whereby the same may be turned, and a forked belt-carrier, g, engaging with the belt, is also fitted to travel over each rod between the bearings thereof, the same being provided with a transverse-threaded opening to receive the threaded rod and with a smooth opening to receive a smooth holding and guide rod, g, secured at the ends in frame A, at one side of and parallel to the threaded red, the purpose of said rod 9 being to hold the belbcarrier against rotary motion on the threaded rod, so that when the'latter is turned said carrier will be moved along the same in one direction or the other, accordin to which way its hand-wheelf is turn ed. The belt M is thereby moved with it, and in consequence changes the speed of the upper cone, it being increased by moving the belt toward the smaller end of said upper cone and decreased by reversing said movement. The top cones are fitted to turn in adjustable bearings K, fitted to slide vertically in suitable housings, K Said top cones rest upon the bottom cones, with the belts M between them, and additional downward pressure may be applied when required by means of vertical holdingscrews it, which may be turned down against the tops of the adjustable bearings K. Said screws are fitted to turn in cap-plates 1, fastened to the tops of housings K A constant pressure is imparted to keep the faces of the disks H against the peripheries of the disks D by means of suitable springs, jin this instance fitted over the shafts I between the side frame A and the hubs of disks H. desired, any other suitable spring device may be used to effect the same result.

The frictional power of the disks D against the disks H may be augmented by providing said disks D with leather bearing-faces 76, as is best shown in Fig. 1. Upon the outer ends of the shafts K, opposite to the disks H on shafts I, are mounted the flanged drawing through pulleys N, around which the wire is wound one or more turns in its passage through the machine, as is usual in other machines of this class. Between said drawing-through pulleys and in a horizontal line therewith are arranged the reducing-dies l, which are held in position in the adjustable holders 0, fastened to frame A. structed in the following manner:

A plate, m, having a vertical holdin g-slot in its front side, is secured to frame A, and in said slot is fitted an angle-plate, at, having a horizontal arm, 07/, extending out laterally from the machine, as is best shown in Fig. 8. Said plate a may be adjusted vertically in the holding-slot of plate m and fastened, after adjustment, by means of a set-screw, 0, and nut 0, the screw being passed transversely through the plates. Upon the horizontal arm n is adjustably fastened the open box or receptacle p, in the front end of which the dieZ is placed against the vertical end thereof, as is shown in Fig. 7. The opposite or rear end of said die-receptacle is made trough-shaped, with the bottom of the trougl'i just below the level of the wire. It is made adjustable on the arm by forming a vertical screw-stud, 01 on its under side, which passes through a slot, 41 in the arm n, and is fastened, after adjustment, by the nut '12, said slot 01 admitting of its being movedlaterally toward and from Said die-holders are con the machine to bring the die-opening in the required position. 3y thus constructing the die-holders 0 it is obvious that the dies I may be readily adjusted either vertically or laterally, so to bring said dies in any desired position, thus admitting of the size of the drawirig-through pulleys being varied to suit different requirements. The wire-drawing block P is preferably arranged vertically, and its shaft 0" is fitted to turn in a suitable bearing, 0', extending out from frame A. The bases of said block rests upon the vertical disk 2, secured to one of the shaftsK, coming in. line therewith, and the block is driven thereby; otherwise the arrangement for driving and regulating said block is the same as that employed for driving and regulating the drawing-through pulleys N, as will be observed by the drawings. The wire is supplied to the machine from a reel, Q, and is drawn forward therefrom through the various dies' to gradually reduce it in size by the block P and drawing-through pulleys N in like manner to other similar machines. It may be supplied with a proper lubricating-fluid in pass ing through said reducing operation by arranging a main supply-pipe, u,-having suitable branches and shut-off cocks, r, over the die-holders, adapted to discharge said lubricant over the wire just prior to its passing through the die. Said main pipe u m( y in practice be connected with any suitable reservoir or other means for supplying the same with the lubricating-fl uid. As said fluid flows out of the die-receptacles p it enters a stationary trough, an, arranged under said receptacles, an d from thence it is in turn discharged through the waste-pipe as, which may in practice be connected with a suitable receiving tank or receptacle.

The lubricating-fluid maybe used over and over, if desired, by combining a suitable force-pump with said receiving tank or receptacle for forcing said fluid back into the supply reservoir or pipes. My invention, ho\ ever, has no relation thereto, and it is consequently not illustrated.

By constructing a wire-drawing machine as hereinbefore described I am en. bled, as will be seen, to adjust the speed of the shafts I K by means of the friction-disks D H, and also the wire-drawing pulleys N and block P, by the friction-cones J L and belt M, so as to vary their speed to a nicety, the shafts being adjusted independently of the wire-drawing pulleys, and each shaft and pulley independent of the other. Being thus enabled to exactly adjust the various parts, and all the parts being driven by frictional power rather than gearing, the wire is drawn through the machine in a very smooth and even manner, without any jerks or vibratory movements, and in consequence a superior quality of wire is produced, especially in treating the finer grades, for which this machine is more especially designed.

I am aware that it is not broadly new to obtain a varying speed or adjustment by means of a pair of friction-disks, as D H. Neither is it new to effect the same result by means of friction-cones and a belt placed between them, as J, L, and M, and I therefore limit my invention to the combination thereof with the other parts of my improved machine, as set forth in the claims.

Having now fully described said machine, what I claim therein as new, and desire to secure by Letters Patent, is
