MACHINE FOR MANUFACTU RING BARBEDVFENCE-WIIRYE.

SPECIFICATION forming part of Letters Patent No. 227,948, dated May 25, 1880.

' Application filed September 19, 1879.

To all whom it may concern Be it known that we, EDWIN A. BEERS, of De Kalb, in the county of De Kalb and State of Illinois, and THOMAS W. EATON, of Chicago, in the county of Cook and State of Illi" nois, have invented certain new and useful Improvements in Machines for Manufacturing Barbed Fence-Wire or Fencing, of which the following is a specification, reference being had to the accompanying drawings, forming Our improvement relates, in a fence-wirebarbing machine, to the mechanism for fi'xing the barb upon the f'encewire; and its object is to provide a device whereby the end of the barb-wire, when the same is being wrapped around the fence-wire, may be crossed from one side of the barbwire to the other, thus forming the kind of barbed fence-wire known as the Beers barbed fence-wire, which is shown in Figure 1.

In the accompanying drawings, in which similar letters of reference indicate like parts, Fig. 1 is a plan view of the machine embodying our invention. Fig. 2 is a side view of the same. Fig. 3 is a cen tral'verti cal transverse secrection indicated by arrow 1. Fig. 4 is a similar view taken on line y y y 3 and looking in the opposite direction, indicated by arrow 2. Fig. 5 is a detail view, showing the cutters, guides, and twisting-shaft. Fig. 6 is an enhook detachable. Fig. 7 is a view of the completed fence-wire. Fig.8 is a perspective View of the cutters with the part a, guide Y, and barbing-shaft O removed.

A is the frame or table of the machine, resting upon four legs, A, the feet of which are secured firmly to the floor by bolts or otherwise, and a and a are the fence-wires, which are to be twisted. together to form the cable a after the barbs have been fixed upon one of them, and a is the barb-wire or wire from which the barbs are to be cut.

B- is an arm extending from and secured to the frame A, which supports two reels or spools, (not shown,) one for each of the wires (1 and a, and B is a like arm, which supports the spool for the barb-wire a.'

G is a long shaft from which all the different 1 thickness.

devices of the machine receive their motion, and is suitably journaled in boxes or bearings d on the standard D. The shaft 0 is connected, by means of the bevel-gear b b, with the shaft 0, upon which the band-wheel c and the fly-wheel o are keyed, and which is journaled in suitable boxes or bearings secured to the side of the slotted standards E and E.

F F and F F are two pairs of guide-rolls, each of which is provided with roughened grooves for the wires a and a. The shafts f andf of the rolls F F and F F are journaled in suitable bearings G G, which rest in slots 6 c in the standards E E. The upper and lower pairs of these hearings are held apart by means of a spring between them, and the upper pair is capable of adjustment vertically by means of the adjusting-screws g.

His a polygon-shaped feed-wheel on the shaft I, provided with a series of lugs or projections, h, on its circumference, in each of which there are two notches, h h, one for each of the fence-wires a and a. The lugs h are placed the same distance apart on the circumference of the feed-wheel E that it is desired to place the barbs apart on the wire a. The shaft I is suitably journaled in boxes or bearings on the braces or arms I, which are secured to the back end of the frame A. dis a wheel keyed to the shaft I, provided on one side, nearits circumference, with a series of pins, 13, having friction rollers or washers z' thereon.

J is a wheel keyed on the end of the main shaft 0, provided on one side, near itscircuinference,with cams orprojection s j j and grooves j j, cut diagonally across its periphery or The thickness of the wheel J corresponds to the distance between the pins 1" d, and the width of the grooves j j to the diameter of the pins 2" 6, including their washers i i". 011 the revolution of the wheel J the cam j comes in contact with one of the pins t", causing the wheel ito turn. The next pin 21 in the series, striking into the groove j, causes the wheel t to continue its revolution as the pin 2" moves along the groove j across the periphery of the wheel J, and the next succeeding pin z" strikes into the other groove j in like manner.

The form and arrangement of the cams jj and grooves j j, in connection with the pins 45 t" on the wheel t, are such that at each revolution of the shaft 0 feedwheel H is made to turn that part of a revolution indicated by the number of notched lugs h upon its circumference, thus feeding or drawing forward the fence-wires a and a each time just the distance the barbs are to be placed apart on the wire a, and, by reason of the wheel J being made of the same thickness as the distance between the pins 43 i, the feed-wheel H is held locked firm and stationary during all the revolution of the wheel J, except when the cams jj and grooves j are passing the pins 43 i.

K K are the feed-rolls for the barb-wire a, keyed to the shafts K K, which are provided with cog-gear k k, meshing with each other. The shafts K K are journaled in boxes or bearings K K, resting in slots k in the standards 70 7c". The upper shaft, K, is connected, by means of the bevel cog-gear l l, with 'the shaft L, which is journaled in suitable boxes or bearings on the standards L and L.

The shaft L is made to turn intermittently or at intervals in the same manner as the shaft I, already described, and by similar mechanism, consisting of the wheel J, with cam j and groove 9', keyed to the shaft 0, and the wheel 47, with pins t', keyed to the shaft L. By this mechanism the feed-rolls K K are caused to turn sufficiently at each revolution of the shaft 0 to feed or draw forward the barb-wire a just such length as is required to form one barb, and during the process of barbing and cutting off the barb the barb-wire a is thereby also held firm and stationary.

The feedrolls K K are provided with one or more corrugated or roughened grooves for the barb-wire a, for the purpose of guiding the same and preventing its slipping when being fed forward and during the process of barbing or wrapping the barb-wire to around the wire a, thus securing entire uniformity in the length of the barbs.

The wire a, upon which the barbs are to be fixed, passes from its spool through a guidehole in the ear M on the arm B, between the guide-rolls F F, through the hollow shaft 0, over the flat guide or support m, around the feed-wheel H, in one set of the notches h in the lugs h, and thence to the twisting and spooling portion of the machine. The fiat guide m is fixed to the standard L.

Thefence-wire a passes from its spool through a guide-hole in the ear M, between the guiderolls F F, through the tubular guide in, which is attached to the standard 0, and thence around the feed-wheel H in the other set of notches h in the lugs h, to the twisting and spooling apparatus.

The barb-wire a" passes from its spool through a hole or opening in the guide-piece N, attached to the standard D, through a like hole in like guide-piece N, attached to the standard 70, between the feed=rolls K K, through the conical-shaped guide or eye a, between the bars T T, which carry the cutters or knives for cutting off the barbs, the end of the barbwire a projecting through beyond the fencewire a and immediately beneath it.

0 is a hollow shaft suitably journaled in boxes or bearings O on the standards 0 in such manner as to admit of a slight reciprocatin g or sliding motion backward and forth in the direction of its length. The hollow shaft 0 extends from near the guide-rolls F F to near the projecting end of the barb-wire a.

0 is the barbing-hook, which is provided with a notch, 0, in its end. The book 0 is made of steel, and is of a spiral form, as if it were a continuation of a thread or spiral on the hollow shaft 0, and is secured in a mortise cutin the end of the hollow shaft 0 by means of a key, so that it can be easily removed and replaced by another in case it should be broken or the jaws of the notch 0 become worn. Upon the revolution of the hollow shaft 0, through which the fence-wire a passes, the barbinghook 0 catches the projecting end of the barbwire a in the jaws of the notch 0 and wraps or carries the same around the fence-wire a.

The hollow shaft 0 has two motions imparted to it-.one a rotary motion and the other a reciprocating motion. Its rotary motion is first in one direction to wrap the barbwire a around the fence-wire a, and next in the reverse or opposite direction for the purpose of extricating or clearing the barbinghook 0 from the formed barb. Its reciprocating or sliding motion is for the purpose of guiding the barbing-hook 0 up under the projecting end of the barb-wire a, so as to catch the same in the notch 0, and for the purpose of guiding the hook 0, and the end of the barbwire a with it, down on one side of the barbwire a at the first revolution of the hook 0, and down on the opposite side of thebarbwire a at the next revolution of the hook 0, (thus wrapping the barb-wire a around the fence-wire a, in the manner shown in Fig. 7,) and also for the purpose of extricating the barbing-hook 0 from the completed barb and withdrawing the end of the hollow shaft 0 and the hook 0 from in front of the barb-wire a, so as to be out of the way of the same when the same is again fed forward to form the next barb. Its rotary motion, as described, is imparted to the hollow shaft 0 from the main shaft G by means of the crank P P thereon, which actuates the segment P, the cogs of which mesh with a pinion or cog-gearing, p, keyed on the hollow shaft 0. The shaft 10 of the segment P is suitably journaled in boxes or bearings p, secured to the frame A. The pinion 10 is made of sufficient length to permit of the reciprocating motion of the hollow shaft Ov without the cogs of the same becoming disengaged with the cogs of the segment P. When the crank P P pushes the segment P the hollow shaft 0 is caused to revolve in the direction necessary to wrap the barb-wire at around the fence-wire a, and when the segment P is pulled by the crank P P the hollow shaftO is caused to revolve inthe reverse direction. i i r Its reciprocating motion, 1 as described,: is imparted to the hollow shaft 0 from .themaiu shaft 0 by means of the lever Q, which is pivoted to the top of the standard or support Q as its fulcrum. One end of the lever Q, is provided with a pin, q, having a washer or friction -roller, q, thereon. The pin q fits and works in a cam or groove, r, cut in thecylindrical surface of the cylinder R, which is keyed to the shaft 0, and the other end of the lever Q is connected, by means of set-screws S S in 'aws S S, with a collar, .9, on the hollow shaft 0. The shoulders s s of the collar .9 are provided with a thread, which works in a corresponding thread on the hollow shaft 0, for the purpose of adj usting,by means of a wrench, theposition of the collar 8 on the hollow shaft 0, so that by action of the lever Q and cam r the barbing-hook 0 in the end of the hollow shaft 0 will be moved exactly into position under the projecting end of the barb-wire a at the time the operation of wrapping the barb-wire around the main wire is commenced.

The form of the cam r is such as to give the.

' ment P any desired number of wraps may be given the barb-wire around the fence-wire. By reason of the barbing-hook 0 being made of a spiral form it is specially adapted to make those kinds of barbs wherein the end of the barb-wire a is crossed in the course of the wrap from one side of the barb-wire a to the other, it not being possible to effect this crossing of the barb-wire by means of the or;

dinary barbin g pin or plug secured in the end of a hollow barbing pinion or shaft, and in order to clear the barbing-hook 0 from the completed barb it is necessary that the hollow shaft 0 have a reverse rotary motion at the same time it is drawn back by action of the lever Q.

T is an upright bar fixed firmly to the frame Aand standard 0. T and T are similar bars, which work up and down in opposite directions in the boxes or guides t t, which are secured firmly to the fixed bar T. The bar T is provided with a long notch or detent, U, in its face or side which faces the bar T, to permit the barb-wire c to pass between the two, and to give room for the end of the barb wire a when the same is being wrapped around the fence-wire a, and to permit of the free motion of the bars T and T without interfering with the barb-wire a. This ,detent or opening U might be cut in the other bar, T, or partially in each of the two bars T and T, and the outer faces of both bars T and T are'scalloped out or provided with detents U to give room for the free passage of the completed barb when the fence-wire a, is again fed forward for. the nextbarb. Each of the bars T and T carries a cutter or knife, t t, for cutting off the barbwire a. Theeutters it are fitted in mortises which pass diagonally through the bars T and T, and their faces 01' cutting-edges are so arranged as to cut the barb-wire a diagonally, thereby pointing the barb at the same time it is severed. The cutters t t are keyed in their mortises in such way as to be readily taken out and sharpened. n is a conical-shaped guide'or eye for the barb-wire a, the point of which extends into the detent U between the bars T and T close up to the cutters t t, for the purpose of holding the barb-wire a firm, and fixed laterally and vertically during the process of wrapping the end of the same around the fence-wire a and cutting ofi -the barb. The guide a is secured to the brace or arm n, fixed to the box or guide it, and is made of steel.

a is an arm attached firmly by means of. a screw, or in any suitable manner',-to the top of the bar T, having a flat foot, it, provided with a guide-groove, u", for the fence-wire a, and V is a lug or projection secured firmly to the bar T, and a pin V, having a broad flat round head,v, rests upon'a spring in ahole in this lug or projection V. By motion of the bars T and T the foot to of'the arm u and the head 0; of the pin V are pressed together, holding the fence-wire a between them in the groove u firm and steadyfroin the time when the operation of wrapping the barb-wire a around the fence-wire a is begun until it, is finished. The arm a and the pin Vare arranged relatively, toeach other on the barsT and T, respectively, so that when the bars T and. T are moved in opposite directions to press the head '0 and the foot it together the bar T is raised and the bar T is lowered sufficiently, so that both the cutters t t are out of the way of the end of the barb-wire a when the same is being wrapped around the fencewire a, and thus, by having both of the bars T and T movable, both thecutters t and t are out of the way, so that the end of the barb-wire a. may be brought down at one revolution on one side of the barb-wire a, or next to the bar T, and at the next .revolution crossed over down on the opposite side of the barb-wire a, or next to the other bar, T. After the operation of wrapping the barb-wire around the fence-wire is completed the bars T and T are again caused to move in opposite directions, causin g the cutters t t to cut the barb from the barb'wire a.

The motions that the bars T and T have, as described, are communicated to them from the main shaft 0 by means of fthe levers W and W. The lever W is pivoted to the standard Io as its fulcrum, and one end is pivoted to the bar T, which it actuates, and its other end is provided with a pin or follower, w, which works in an eccentric groove or cam, cut in the side of the wheel w, which is keyed to the shaft 0. The lever W is pivoted at its outer end to the lug or earX on the frame A, as its fulcrum. Its other end is pivoted to the bar T, which it actuates, and near its middle it is connected with and actuated by the lever W by means of the connecting-bar X, one end of which is pivoted to the lever W and its other end to the lever W. The action of the levers W and W, in connection with the cam w, is such as to give the bars T and T their required motions, already described, and to keep the foot u and the head 11 pressed together during the operation of b'arbing or wrapping the barb-wire a around the fencewire a.

Y is a curved guide-piece attached to the projection Von the bar T, for the purpose of guiding or slightly inclining the projecting end of the barb-wire 00 toward thenotched book 0, thereby insuring that the barb-wire a be caught in the jaws of the notch .0.

The devices for twisting the fence-wires af and a into a cable and for spooling the same may be made in any of the ordinary forms of such devices in fence-barbing machines.

The operation of our invention is as follows: 1

The fence-wires a and a and the barb-wire a being passed through the machine in the manner described, and being in position for fixing a barb upon the fence-wire a by motion of the bars T and T, the fence-wire a is first clamped between the foot u and the head of the pin V, and at the same time the barbing-hook 0 on the shaft Ois moved into position, catches the projecting end of the barb-wire a, and wraps the same around the fence-wire a, as described.

By motion of the bars T and T the formed barb is immediately severed from the barbwire a on a diagonal cut, thereby pointing the same, and at the same time the barbinghook o is withdrawn and cleared from the completed barb, and the fence-wires a and a, simultaneously with the barb-wire a, are again fed forward for the next barb, as described.
