CORNELIUS VAN DERZEE, OF ALBANY, NENV YORK, ASSIGNOR TO DAVID H. MATHIAS, OF SAME PLACE.

MACHINE FOR STRAIGHTENING, MEASURING, CUTTING, AND COUNTING WIRE.

SPECIFICATION forming part of Letters Patent No. 311,213, dated January 27, 1885. Application filed November 15, 1883. (N model.)

To all whom it may concern.-

Be it known that I, CORNELIUS VAN DER- ZEE, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented a new and Improved Machine for Straightening and Cutting Wire to Definite Lengths,.of which the following is a specification.

My invention relates to a machine which is provided with mechanism for straightening the wire as it is drawn from the coil, and

mechanism for drawingthe straightened strand out to definite equal lengths successively mechanism for cutting the wire at points for- 1 ward of the points where the wire is held;

mechanism for releasing the cut wire; mechanism for counting the wires as they arecut and delivered from the machine, and mechanism for delivering a given number of wire strands simultaneously, and in a lot, from the machine without necessitating a stoppage of the same.

My invention consists of the several devices and combinations of devices hereinafter described and set forth; and the objects of my invention are to provide mechanism for operating progressively and successively on the wire (from a coil) to straighten the same, and run outand cut off strands of equal length, and count the same and deliver the strands in lots of a definite number from the machine, and thereby obviate the necessity of employ ing several machines or instruments and counting the wires, as heretofore required in produing wire strands of uniform length. I accomplish these objects by means of the mechanism illustrated in the several views in the accompanying three sheets of drawings, containing nine figures,and forming a part of this 0 specification, in which- Figure 1 represents ahorizontal view of the machine from above. Fig. 2 is a sectional elevation of the same. Fig. 3 is an end View taken at lineNo. 1 in Fig. 2. Fig. 4is a crossseetional view taken at line N o. 2 in Fig. 2. Fig. 5 is a cross-sectional view taken at,line No. 3 in Fig. 2. Fig. 6 is a cross-sectional view (on an enlarged scale) of runner D, with parts in a normal position,taken at line No. 4 50 in Fig. 8. Fig.7 is a cross-sectional view, on

the same scale, of the runner,taken at line No. 5 in Fig. 8. Fig. 8 is a view of runner D when moving in its way and viewed from below. Fig. 9 isa view of the same from above.

The same letters of reference refer to similar parts throughout the several views.

In the drawings, A represents the frame of the machine. B B are sprocket-wheels, which are mounted on shafts b I), supported inproper bearings, a a, made with upright brackets secured to the frame.

Carried by sprocket-wheels B B is endless link-belt O, which is actuated through sprocket-wheel B by band-wheel NV, driven by any preferred power; ora crank maybe employed if manual power is used.

Secured to link-belt C are two or more devices, D, which I denominate the runners. These runners are eachpivoted at its forward end to the chain belt, as at c, and are each provided with a gripping device for engaging with the wire to be drawn out, and with a nipper, by which the wire is cut.

I will hereinafter particularly describe runners D in all their'parts, and also in connection with other devices, which are provided to operate with the same.

At the rear end of frame A is arranged a wirestraightener, E, which is composed of four rollers, e, c, e, and 0. These rollersare so arranged in relation to each other that the wire 7 worked by them will be continuously turned back on itself atleast twice before it is finally run forward. In this arrangement the final roller 6 is set with its wire-bearing side on a line coincident with the line of the center of the machine, and with the line of the straightened wire being drawn into the machine.

Set opposite to the wire-bearin g side of final o roller e, and to adistance from the same about equal to two of its diameters from centers, is the first turning-roller, c, and a little back from a line drawn through the centers of both said rollers is the second turning-roller, e, of 5 thesame diameter.

Set at a point back from roller 6 and oft" from a line drawn through the center'of the same and parallel with the'line of the straightened wire strand IV, is starting-r0ll er 6. I pre- :00

fer to make each of these rollers with a diameter about one and three-quarters inch, and

with a wire-receiving groove of about oneeighth of an inch in depth in the periphery, and all on the same horizontal plane. In the arrangement of the group of rollers 6, c and 6 those rollers are set with their centers at points relatively triangular, with centers of rollers e and e" on a line corresponding with the base of a triangle, and with center of roller- 6 at a point corresponding with the apex of the same.

In the arrangement of the group of rollers e, e, and 6, their centers are set relatively triangular with center of roller (2 at apex and centers of rollers e and e at the base of the triangle, so that in reference to the triangular arrangement of the rollers in both groups the roller 6 will be relatively at the apexin both cases, and the wire, when drawn forward,will be run in direction of arrows 1 in Fig. 1, and be delivered from roller 6 straightened. Rollers e, e, e are mounted on vertical spindles, which are stationary, while roller 6 is mounted on a vertical spindle, which is attached to vi brating bracket 6 adapted to oscillate from pivot 6 Secured to the bed of the machine at a point relatively rearward of roller eis guiding-piece d,- and secured also to the bed forward of roller a is the wire-guiding piece d, the eye of which is in a line drawn from the wire-bearing side of roller 6 central through the machine in its longitudinal direction.

As above stated, two .or more runners D are employed with endless link-belt O. I prefer to use three of said runners, though a larger number may be employed when the length of the endless band will be increased proportionately. These runners are made each to be a duplicate of the other or others employed, therefore a description of one will suffice for the others. Runner D is composed of horizontal platef, fixed block g, provided with pinching-face g and cutting-edge g pinching-cam h, provided with lever h,spring z, operating with lever of cam h, pivoted cutter J, provided with lever J and spring K, operating with the lever of the cutter. Shoes Z Z, secured to the rear end of platef, are also provided for supporting the devicein a 1101izontal position.

All the above-mentioned parts of this runner are shown in Fig. 8 (view of the runner fromits lower side) to be arranged as follows: Block 9 is situated between pinching-,cam h and cutterj, and has its pinching-surlace g a short distance from the face of the cam,which is pivoted at apoint on plate f, as at h", and on the side portion of the same opposite from block 9, and when lever h is moved from position shown by full lines to that shown by dotted lines in Fig. 9, the wire will be nipped between block 9 and cam 71. Block 9 has made in itsinner and off corner a recession, made on the curve of a true circle, as shown at m, and

the line ofedgegjat the intersection of the nipping-surfaceg and curved line m, is the cutting edge on said block. The cutter j is pivoted about at the middle of the width ofplatef, with its head j made with a curvature corresponding with the curvature of recession m in block 9. This head j has its half portion toward block 9 sunken at n in relation to the lower side of the other half portion of the cutterhead, as shown in Fig. 7, and the line of edge produced at the intersection of line of surface a with the curved line a ofsurface ofthe projected half portion of the cutter-head, as atj, is made the cutting-edge,which will coact with theline of edge g", made with block gto cut the wire when lever j is moved from position shown by full lines in Fig. 9 to that of dotted lines in the same figure. Spring 2' operates to throw cam h to its normal position, as shown by full lines in Fig. 8, and spring It operates to throw cutter j to its normal position."as-

shown by full lines in the same figure. This runner is pivoted to a link, L, of the endless belt 0, (shown in Figs. 2and 9,) and is carried by said belt in direction of arrow 2 when operating with the wire, and is returned idle by being moved in direction of arrow 3 in Fig. 2. These runners are moved by belt 0 through way F, made in the top surface of frame A. This way has on one sidethe longitudinal flange 0,1nade on plate M and setting off from the side of plate f to a distance suiiicient to permit lever j to move freely within said way. From the upper edge line of flange 0', plate M is extended inwardly in a horizontal manner, and has'flange-shoulder 0, which bears against the edge of plate f, and also a horizontallyprojecting lip, 0", which bears on the upper side of the side margin of said plate, as shown in Fig. 8. On the opposite side of the runner is the bar K, set off from platefot'the runner to a distance sufficient to have a firm bearing against the end of lever It of the pinching-cam h, when it is in the act of pinching with block 9 the wire, as shown by full lines in Fig. 8. This bar is movable and may be set nearer to or farther from the edge of platef of the runner by set-screws s,or inclined wedges or cams, as may be preferred, and it is covered over by plate M through the outer side edge of which set-screw .9 works. The inner edge of plate M has flange-shoulder 0 bearing against the edge of plate f, and horizontally-projecting lip 0, bearing on the side margin of said plate, as shown in Fig. 8.

Fixed in the side of way F,'in which lever h of the cutter moves, is the inwardly-projecting tripping-piece q, against which lever j strikes at the moment the cutteris to be operated to cut the wire, as illustrated by dotted lines in Fig. 8. Two plates, M M, made similar to plates M M, (with the exception which will be hereinafter described,) are fixed to frame A over way F, and plates 3 and M are arranged intermediate between plates M M, and M and M and over way F. The flanges 0 and lips 0 are continued in the intermetinued beneath plates M and M for having bearing against the end of lever It of the pinch ing-cain h, to hold it in action with the wire being held. This movable bar K terminates beneath plate M at a distance of about four inches (more or less) from the forward end of said plate, as shown by full lines in Fig. 9, so as to leave chamber-room O, that when the runner has been carried forward sufficiently to bring the end of pinchingcam lever h to the end of bar K, the said lever will be free to be moved to an open position, as shown by dotted lines in Fig. 9.

Fixed in way F, at plate M and at a point a little forward of the end termination of bar K, is the projecting trippingpiece q, which sets relatively nearer toward runner D than trippingpiece g. This second tripping-piece, q,is placed at such a point as will cause it to operate with the lever of the cutter at the instant the lever of the pincher reaches the end of bar K, and this tripping-piece projects inward to a distance sufficient to force lever j against lever h, so as to throw the latter forward toward its normal position, as indicated in dotted lines in Fig. 9. 1

Made central in the width of the bed ofthe machine is the longitudinal vertical slot N, through which the wires, when out and released by the runners, will fall, and arranged beneath the bed and below slot N is arevolving rack, Q, provided with shelves 0" for bolding the cut wires. Secured to one end of the revolving rack is plate r, provided with as many perforations, r'fl'as there are shelves, in which perforations detent t works. This detent is preferably operated by lever t, actuated by projection t", secured to ratchet-wheel t and spring 1. Ratchet-wheel t is provided, preferably, with fii'ty teeth, and is operated by pawl a, pivoted to lever a, supported by spring a", and this lever is operated byrunners l) striking against its upper end. A dial numbered to fifty and a pointer carried by the ratchet-wheel form register R. It should be understood that the link-belt should be of a length sufficient to receive the number of two, three, or four runners D at equal intervals apart with each interval of length of distance equal to the length of the wire to be cut, and that the length of this belt is to be adjusted accordingly as the length of the wires are to,

be cut longer or shorter by the addition or removal of links from the belt at places between runners D, and accordingly as this belt is lengthened or shortened sp rocket-wheel B and plates M M are to be shifted in a corresponding direction. When the belt is lengthened, annex-plates M M corresponding in form of parts to plates M M are fixed to the bed to fill out the intervals between the latter plates and plates M M, and when the belt is shortened these annex-plates are to be removed.

The manner in which the several parts of my improved machine operate is as follows: The end of the wire is run from a coil mounted on a spool (not shown) and passed through guiding-piece d to the straightening rollers E, when the wire is brought first against roller 0 and thence passed around roller e, and thence back around the rear side ot'vibrating roller and thence forward to the inner side of final roller e, as indicated by arrows in Fig. 1. The wire is then carried forward and passed throughguiding-piece d and thence to one of the runners D, where itis secured by the pincher of one of said runners. Sprocket-wheel B is then revolved, so as to carry the endless belt 0 in direction of arrow No. 2 in 2, when runners D, D, and D in Fig. 2. will be carried with it. \Vheu runner D is drawn into way F, the lever h of pinching-cam 72 will be moved by bar K toward platef of the runner and force cam lb against a side of the wire lying against the pinching side surface of block 9, and the wire will be thereby firmly held. As the runner D is drawn through way F the lever j of the cutterj will move freely therein until said lever strikes tripping piece q, when the cutter will operate with the wire to sever the same just forward of the point where the pincher operates with the wire to hold the same. The forward movement of runner D being continued, the lever of pincher h will have bearing against the face surface of' bar K until it reaches the forward termination of the same, and at the same time the leverj' of eutterj will be brought in contact with tripping-piece q and forced from position, as shown by full lines in Fig. 8, to that shown by full lines in Fig.9, when said lever will be thrown with considerable force against lever h of the pincher, and throw the latter forward from position in full lines to that of dotted lines in Fig. 9, when the lover of the pincher will be thrown out toits normal position in the chamber-room. O, to move therein unobstructed, and the pincher be thrown out of pinching contact with the wire, and the wire will drop down through slot Non one of the shelves-of the revolving rack Q beneath. Just before runner D is made to drop the first cut strand of wire, runner D will be carried down to the bed of the machine at the rear of sprocl et-wheel B, and will so drop on said bed as to receive the wire between pincher h and block 9 as before, and when the runner is drawn forward, bar K will operate the same as before to force the lever of pincher hinward, when the same operations of parts will be had as with the first runner. The operations being continued, each runner will be carried down to the'wire, and will grasp the same, and at a proper time out and release the length of the wire thus drawn out and out. As each runner is being carried upward in front of sprocket-wheel B, as shown by dotted lines in Fig. 2, the rear end of plate f of the runner will strike against lever to and force it to a short distance back, and thereby operate to move ratch ct-wheel fione notch th rough pawl a, when spring a will carry lever a and pawl 20 back. When ratchct-wheel f has been moved fifty notches by as many movements of the pawl by the action of the runners against lever a, the projection t secured to the ratchet wheel, will press on lever t, and thereby draw detentt from perforation r in plate 1-, attached to the end of the revolving rack, when the weight of fifty wires on the shelfwill force the rack to revolve to a distance sufficient to dump the lot of wires therefrom, when the spring t throws detent into engagement with another perforation, 7- in plate 1*. The pointer on the ratchet wheel will be carried one point at each movement of said wheel, and count the wires as they are cut. I prefer to use link-belts, though endless bands or cable may be employed to carry the runners.
