T0 @ZZ whom it may concern,.-

Be it known that we, EUGENE R. MA'rTnsoN and WILLIAM J. Horror-riss, citizens of the United States of America, residing at Joliet, in the countyof Will and State of Illinois, hare invented certain new and useful Improvements in Vire-Barbing Machines,- of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation; Fig. 2, a plan view on the top. Fig. 3 is a cross-sectional view of Fig. 1 on line 1, looking toward the rear of the machine, .designed to more clearly show the barb-wire feed with relation to the cutting-off dies or shears and the barb-grasp ing and holding jaws; Fig. 4, a view on the outer, end ot' one of the strand-wire coilers, showing the mechanism by means of which the coilers are prevented from rotatingI backward. Fig. 5 is a perspective view of the cam-wheel L'L at the front endof the machine, which cam operates and governs the movements of the` reciprocating barb grasping and holdingjaws, causing said jaws to grasp enough barb-wire to form a barb, movei'orward with it and hold ituntilthestrandwircs are coiled on it by the strand-wire coilers, then release it and recede; Fig. 6, a view on the inner end ot' one of the 'coilcr shafts, showing the pawl-and-ratchet mechanism, by means ot which said coilershaft is caused to rotate in one direction only. Fig. 7 is a cross-sectional View ot' Fig. l on about line' 2, designed to more clearly show the strand-wire ceilers and the mechanism by means of which they are operated. Fig. 8 is aplan view on the top ofthe inner ends of 'the two strand-wire coilers, and a horizontal cross-sectional view of the upper 'barb-grasp ing jaw, designed to more clearly show the precise manner in which the coilers coil the strand-wires around the barb. Fig. 9 is aperspective view ofthe reciprocating head Hdetached from themachine, showing the barbgrasping and holding jaws Pi3 and l?L attached thereto, designed to show the construction and arrangement of these parts. Fig. l0 is an edge view of a portion of the barb grasping and holding jaws l?3 and P4, showing how their faces are formed to press a crimp in the middle ofthe barb. Fig. ll is a plan view of that 5o and Figs. 14 and 15 are perspective views ot' 60 the finished barbed wire, it being the product of the machine. v The invention in this case consists in a ma -chine for making barbed fence-wire, and is designed to automatically attach a pair of 65 strand-wires to the barbs, consist-ing of short pieces of wire pointed at each end and crimped in the center by ceiling the two strand-wires on said barbs-one on either side of the crimp in the barb-either in the same or in opposite directions from each other, as may be desired, thus ceiling the strand-wires on the barbs to hold them on, instead of ceiling the barbs on the strand-wires, as has usually and invariably been the case where wire barbs are used, forming what is termed a two-strand twopointed77 wire barb.

Referring to the drawings, A represents the main frame or bed of the machine mounted on suitable legs, A, at each corner. The hangen boxes E2 Ej are attached to one side of the bed A to support the drivevshaft S. On this driveshaft- S is located the sprocket-wheel l?, which drives the machine by means of a sprocketchain from the power. (Not necessary to be shown.) There are also keyed to shaft S the miter gears B B5, that respectively mesh with the n1iter-gears B" B, keyed on the countershafts S S, to drive them, and also the cam L4, that operates lever L to reciprocate the sliding plate L2, that operates the toggles, to cause the jaws I3 I)l to grasp the barb.

To the rear end of shaft S is keyed the cog-wheel G, which, through the medium of idler cog-wheel G and cog-wheel G2, drives 95 the twister T, which is of the ordinary pattern and forms no part of this invention.

Counter-shaft S is attached to the bed A by means of han ger-boxes, as shown in Figs. land 3, and has keyed to it the two cams G3 G3, of the form shown in Fig. 1, having cam-channels of the form shown by the dotted lines in said'igure. These two cams drive the coiling-shafts c c, which are located across the top of the machine in suitable boxes, asshown in Figs. 1, 2. and 7, through the medium of the two oscillating arms, c3 c3, keyed on the rockshaftS, boxed to the cross-bars Al of the machine, as shown in Figs. 1 and 7; The roller-wrists U U on the side-s of these oscillating arms c3 travel, respectively, in the camchannels of the cams G3 G3, and when said cams rotate, the form of their channels causes the said arms to oscillate back and forth at their upper ends, where they are provided with the toothed segments ci c2 for engaging with the cog-teeth c', forming an integral part ofthe head e, by means of which said head e and cog-wheel c are rotated first in one direction and then in the other once around, according to the oscillations of said arm and segment. The head e and cog-teeth c integral therewith are slceved on over the coiling-shaft c, and are held thereon between the box of said coiling-shaft and its integral ratchyet-teeth t. (Shown in Fig. 6.) r1`he two coil- Ving-shafts c c and their driving` mechanism are duplicates, so that a description of one will su'iice for both. The said head e is provided on its inner surface, between it and its ceiling-shaft, with a series of spring-pawls, t. (Shownin Fig. 6.) These pawls t and ratchetteeth t cause the coiling-sl'lal'ts to rotate intermittently in one direction once around. The rear ends of the coiling-shafts c are provided with annular collars m, held thereon by means of set-bolts m', (shown in Fig. 7,) to hold them in their respective boxes. The heads of these set-bolts m project, as shown in Figs. 4' and 7, so the pawl mi, engaging with it, wil1.pre\ ent the backward turn of'said coiling-shafts. The front ends of the coilingshafts c c are located to stand directly' opposite to each other as far apart as the barbs are long, and are each provided on their facing ends with the nipples a n, located at one side from the center of the coiling-shalts, lfrom which nipples the strand-wires w w emerge `through proper holes ruiming longitudinally through the coiling-shafts, as shown, for the purpose of carrying the strand-wires out far enough to coil themon the barb near its center, and leave room between the ends of the coilers for the barb while the strands w are being coiled on it, as shown in Figs. 2, 7, and 8. rlhe strand-wires pass into the machine through these coiling-shafts, one from each side, as shown in said figures, and are by thein coiled'ou the barb in the manner and form Shown particularly in Figs. 7, 8, 14, and l5, as will be more particularly set forth hereinafter. The counter-shaft S2 is attached to the shown in Fig. 1, and has keyed to it the'miter gear-wheel B, cam-wheel G, and eccentric y. Gam-wheel G4 reciprocates the sliding head H, (shown in Figs. 1, 3, and 9,) through the medium of oscillating arrn c4 and link P2. Arm c4 is boxed on shaft S3, as shown in Fig. l, and is provided with a roller-wrist on its side, as shown hy the dotted lines in said figure, that travels in the cam-channel on theside of camwheel G4. The upper end of arm cIt is connected by means of link P2 with the reciprocating-head H, as shown in Figs. l and 9. Vhen cam-wheel G rotates, it will, by means of such connection with head H, reciprocate it back and forth in proper guideways on the bed A and in frame B, attached to bed A, as shown in Figs. 1, 2, and 3. This reciprocating head is for the purpose of supporting and carrying the barb grasping and holding jaws P3 and I. Looking at Fig. 9, the lower jaw, P4, is shown as attached permanently to the lower part of sliding head H, while the upperja'w, P, is shown as attached permanently to the outer end of arm D2, the inner `end of which pivots to IOO and 3. The feed-rollers v vare keyed to shafts that have cog-wheels keyed to their opposite ends to drive both feed-rollers at the same vclocity. The shaft of roller chas a'ratchetwheel keyed on it at about the center, as shown in Fig. 1, and an arm, R, boxed on it, to the side of which a spring-pawl is pivoted to engage with said ratchet. To the outer end of arm Ris pivoted the connecting-rod Rt, (shown in Fig. 3,) which forks over shaft S, as shown 'in Figs. land 3, between a collar on the outer vin the outer end of arm R6. (Shown in Fig. 3.)

The barb-wire passes from between these feedrollers 'v o, first through the guide-tube wz, as shown in Figs. 2 and 3. thence between the cutting off dies in heads E z, and is delivered between the jaws P P", and of sufficient length to make a barb. At the instant enough wire fw is so fed in between the-said jaws for a barb, the sliding plate L2 (shown in Fig. 1) begins to move forward by means of its connection with cam Li on'the end of shaft S, through the medium of the arm L, pivoted onthe machine IIO ISO

alaceo on bracket L, and the link L. plate is provided with the toggles a and c and the flanges c2, to back up and assist in operating said toggles. The upper ends of toggles a, pivot to the side of trame B2, and their lower slotted ends to the side of said sliding plate, by means of propel' screwbolts. The toggles ct pivot at their upperends to the side of sliding plate L2 by means of proper screw-bolts, while their lower ends hang down loosely to rest on the upper surface of the bar D, which in turn rests and rides on roller D. The bar D is loose, but held in place by means of the screw-bolt b3 passing down loosely through the overhanging upper end of standard HQ and screwed tirmly into said bar D, so it can have vertical movement to a certain extent. A pair'of side plates, B', )revent said bar D from falling outsidewise. The forward movement ot' said sliding plate L2 will cause said toggles to depress said bai-D down on roller D', and thus cause jaws P3 P to close and iirmly grasp the barb, and by the form of theirfaces, as shown in Fig. 10, crimp it, as shown in said figure. The sliding head H then begins to move forward by means of its said connection with cam G4, and as soon as it has so started forward, the cutting-ott' dies in the heads E e sever the barb b loose diagonally, to leave it pointed, so it can be carried forward by the jaws P3 P* to the ceiling-shafts c c. The barb is then carried forward by said jaws until its points are between and opposite the centers of the two coilingshafts c c, and are held firmly until the said ceiling-shafts rotate with the two strand-wires to coil each one around the extending prods ot' the barb on either side of said jaws, one on either side of the central crimp in the barb, as is shown in Figs. 7, 8, 1li, 15. The form of cam L then causes sliding plate L2 to recede, which op`ens the toggles a d and relieves bar D from pressure, which permits the jaws l? lL1 to open by means of the upward pressure of spring M on the under side of arm DI". (Shownin Fig. 9.) This causes saidjawsto release their grasp on the barb, which requires their servire nolonger, asitis then held within the coils ofthe two strandwires. At theinstant the barb is so released the sliding head H moves back to its original position ready for another like operation. The two strand-wires are thus each coiled around the barb once, one on either side of the central crimp in it, to i'orm such a barb as is shown in Figs. 14 and 15. The

' strand-wires may each be coiled on the barb in the same direction, as shown in Fig. 141, or in opposite directions, as shown in Fig. 15. The only change necessary in the machine would be to reverse one ofthe cams G3 on shaft S', which would cause the arms c3 to be reciproc-ated in opposite directions. The lower cutting-off die is secured in the head E of the machine, as shown in Figs. 1, 2, 3. The upper cuttingdie is secured in the head zof the oscillating arm a. (Shown in said figures.) Said oscillating-arm e is pivoted, as shown in Fie". 2, on the upper face of standard-head E, and

This sliding l is caused to oseillate by :means of the cam F2 on shaft S, through the medium of oscillating arm F pivoted to the side of the bed A, as shown in Fig. 3. Cam-wheel l?2 on shaft S in its revolution impingcs against the lower end of arm Fand causes it to oscillate, and by that means through the medium of lilik F, oscillates arm a for the purpose of causing the said cutting-off dies to sever the barb loose, as stated. A coil-spring attached to the outer end of arm'le returns it, as shown in Fig. 2. rlhere is nothing particularly new in the cutting-off dies or their operating parts or mechanism, and any suitable mechanism for cutting off the barb may be used instead of the one shown. After the strand-wires have been thus coiled on a barb, theyV must be drawn along through the machine far enough, so the next succeeding barb can be attached in like manner. This is accomplished by that portion ofthe machine denominated the takeup.7 (Sh-own in Figs. 1,2, and 11.) Looking atsaid gures, Jz are a pair of parallel guidewnys attached to the machine, as shown in Fig. 1, on the bed J", forming a part of the standard l-l and on the standard K4, both said standards standing on and bolted to the bed A, as shown in Fig. 1. These guideways are ofthe form shown in crosssection in Fig. 13.

K is a reciprocating head which reciprocatesin the grooves ot and between said guideways by means of the eccentric y on shaft Si, through the medium of oscillating arm K3, boxed on shaft S", link K2, and lugs K, as shown in Fig. 1. A pair of barbguides, J', are secured permanently to the upper surface ot' reciprocating head K, and are ot' the same form in cross-section, as shown at J in Fig. 13, having the longitudinal grooves e for the prods ofthe barbs to travel in. On the up- 'per side ot' one ot' these guides J is attached these guides J', the prods of the barbs traveling in the grooves e and the strand-wires between them. As the eccentric y reciprocates the head K, each move toward the twister will draw the barbed wire along the required distance to place the next succeeding barb in the strand-wires by means ot' the springpawl clos- IOC) IlO

ing on the strand-wires to hold it firm on the I head K, so that the reci procation of the said head K i ntermittentl y draws the barbed strandwires along out ofthe machine to the spooler and twister T. lVhen the strand-wires are first coiled on the barb, the coils or loops in them are left by the coilers spread apart to some extent and not nearenough the center of I3@ the barb on account ofthe jaws P3 l?4 being in the way.

It is necessary before the barbed Wire leaves the machine to compress the two coils of the two strand-wires toward each other to the center of the barb, so that they may be in close contact with each other. In order to accomplish this, the strand -wires after they are coiled on the barb are rst drawn between a pair of compressing-jaws, J, that are adapted to open and close on them, so as to compress the coils, as aforesaid. These jaws are shown at J in Fig. 1], and an end view in Fig. 13. They are located on the upper face of the fixed head K, which is held firmly between the guides Jl at the end toward the coilers, as shown in Fig. l1, and are pivotally attached thereto, as shown in said ligure, so that their ends toward the coilers may open and close, and they are provided on their under sides with integral lugs or pins r. (Shown by the dotted lines in Fig. 11 and on the bottom in Fig. 12.) These lugs pass down through the slot r in head K5, and extend below the bottom of said head through the slots rg in the reciprocating plate J 3, which is attached, as shown in Fig. 11, to the under side of reciprocating head K, and is caused to reciprocate by means of its attachment to head K.

Fig. 12 is a plan View on the bottom of rev ciprocating plate J3 to show its form, and to show its slots r" with thelugs 1^ of jaws J passing through them. As the plate J reciprocates by means of its attachment to head K, it will, by means ofsaid lugs r passing through its slots r2, open and close the jaws J. W'hen head K is nearest head K5, the lugs r will be in the eccentric portion of said slots, and thereby open the jaws J, as shown in Fig. 11. Thesejaws are provided with the longitudinal grooves e, as shown in Fig. 13, for the barb-prods to travel in. When head K reciprocates toward the twister T, it will draw on plate J3, and cause it,by means of the slots r2 and lugs 1" ,to close said jaws J up against the sides of the coils of the strand-wires on the barb, and compress them toward each 'other toward the center ofthe barb to leave the iinished barbed wirein the forms shown in Figs. 14 and 15.
