. Aipncationmedauly16,1883. v(Eenmaal.) I

Re it known that I, VILLIAM WILSON, J r., of Greenville, in the county of N ew Castle and State of Delaware. have invented auImproved Apparatus for MakingBarbed FenceWVire,

of which the following is a specification.

The fence-wire which my apparatus is de.- signed to manufacture is composed of asingle strand which is, at predetermined intervals along its length, Ytwisted upon itselfv so as to form laterally projecting necks orshanksA which terminate in two projecting extremities, spurs, or barbs. l

My apparatus is designed, first, to twist a loop upon a continuous wire, 'and then cut open or divide the loop, so as to make it into two spurs or barbs.

Incidentally to the accomplishment of the above result, my invention relates to a class of mechanism which is used to twist a loop upon wire, and employs many ef the instrumentalities found in a certain improved apparatus for looping and cutting wire invented by me, application for patent for which was executed by me July 2, A. 'D. 1883-, and iiled in the United States Patent Office July 16, A. D, 1883, Serial No. 100,917, the said apparatus being an improvement uponl a machine for looping and cutting wire invented by me and patented t'o me in and by Reissued Letters Patent No. 9,404, dated October 12, 1880.

In order to a thorough comprehension of my present apparatus, brief reference to my former patented invention and a redescription herein of such parts of my improved apparatus for looping and cutting wire as are employed in my 'present apparatus are essential.

My former patented invention consists, essentially, of a frame upon which revolves a circular horizontal table, which carries upon its upper surface a series of twisting-hooks operated bypinions secured thereto, which at stated intervals engage with racks supported from the frame, so as to revolve'the hooks and twist the wire fed to them, andalso carries a correspondingseries of cutting devices employed to cut the looped wire to a given length, the cutting ,devices beingoperated by a cam, which is situated beneath the revolving table in the frame-work of the' machine. I

In Inyyimprovedapparatus I employ two circular tablesl or heads, whichare mounted in propinquity upon a horizontal shaft, which occasions their common revolution in vertical planes. The twisting-hooks are secured upon the periphery of the tables, and are operated through pinions engaging with exterior fixed racks, asin' my former patented'apparatus.

The cuttingdevices, however, which a-repro-v vided for cutting off the wire in short sections having each a loop on one extremity, are dispensed with inrmy present apparatus, and in their stead are substituted a cutting arrangement for splitting or cutting open the loops, i 1

so as to form the barbs.

rIhe wire-feeding devices, or those which diL rect the wire to the looping devices, are precisely the same as those of my improved loopA ing apparatus,and my present apparatus may,

ingeneral terms, be said to consist of my improved looping apparatus without the cutting*- off chisels and with the addition of aloop cut; ting or splitting mechanism.

A preferred form of a convenient embodiment of my invention is represented in the drawings, and hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan View of an apparatus conveniently embodying my invention. Fig. 2 is a side elevational view'of the same, sight being taken in the direction of the arrow below Fig. 1. Fig. 3 is an end elevational view of the same, sight being taken from the right-hand side of Figs. land 2. Fig. Ltis a sectional elevational `f the frame-worlrand carrying the bearings b of 113 the horizontal head-shaft C, upon which the heads D D are mounted face to face. These heads are preferably constructed "as flanged disks, the disk being a face-plate designed toy carry the circumferential flange constituting the periphery of the head, and upon which the twisting-hooks are mou nted 5 but they may be of any other construction, as. they are mere rotary devices,upon the peripheries of which the twisting-hooks are carried.

One extremity of the head-shaft is provided with a bevel spur-wheel, E, which engages with a beveled pinion, F, which is mounted upon the driving-shaft G, the journals ot'- the latter being supported from the frame-work bythe brackets f/ or otherwise, as convenience of manufacture may dictate.

Motion is imparted to the driving-shaft from lthe pulleys H. The driving' shaft is also equipped at its extremity opposite to the pulleys with a crank-wheel, 1 the wrist-pin of which is attached to one extremity of a pitlnan, J, the opposite extremity of which isv c onnected with a slide bar. K, adapted for longitudinal reciprocation through the journals k, which are formed in or applied to minor standards 7., erected from the framework.

rlhe slide-bar is equipped with a peripher- .ally-groovcd guide feed-roll, L, whose axle is parallel with the slide-bar, which is the device employed to carry and feed the wire, which is fed in from the reel around said roll alternately to the twisting-hooks of the two heads, the timing of the throw of the slide-bar being such that the feed-roll is advanced to meet a particular hook on either of the heads just at the instant that that hook in the rotation ot' the head presents itself in position to engage the wire, the retreat of the feed-roll. being also such that it presents the wire to the next succeding hook upon the opposite head in time to supply said hook with the wire.

The twisting-hooks being, as represented and hereinafter explained, set alternately, as considered with respect to the two heads, the feed of the wire, as will be readily understood, and as is well shown in Fig. 1, is irst to one hook on one head, then to the next succeeding hook on the opposite head, then to the next succeeding hook on the head first considered, and so on continuously, so long as the supply of wire fed to the machine and the rotation of the heads continue.

M are the twisting-hooks, being of the construction represented in the drawings, and essentially of that described in my former patent-that is to say, a housing, m, secured radially to the peripheral face ofthe head, serves as a bearing for the hollow spindle m of the hook, said spindle being parallel with the head-shaft, and being provided upon its outer extremity, or that which is opposite to the hook, with a pinion, mx. The spindles and their pinions are so set that in the revolution of the head with which they are connected they successively encounter and are rotated by the teeth of a stationary rack, N, erected from the framework, and in any covenient manner secured thereto. In the apparatus represented in the drawings these racks are shown as adj ustably secured to the suppledle is surrounded by a spring, m, which abuts between the collar mt and one arm of the housing m., and which serves to permit of the drawing forward of the hook as the wire shortens up when the hook twists it.

So unich of my present apparatus as has just been described is found in my improved looping-machine for which, as stated, l have made application for patent, the only difference being that the spindles of the hooks of said looping-machine are not made hollow, as in my present apparatus. y

The object of making the hook-spindles of my present apparatus hollow is to adapt them to contain spring-chisels l?, which are adapted to longitudinally slide within the spindle, and which are provided with a head, p, bctween which and the pinion mx, which the spindle carries, is coiled a spring, p', which acts to draw the chisel back after it has been struck forward.

The inner face oi" the hook is formed into a cutting-edge, as will be observed by reference to the drawings, and especially to Fig. l, and against this edge the edge of the chisel strikes and occasions the severance ofthe wire which is between the hook and the chisel.

The instrumentality which I employ to occasion the advance ofthe respective chisels is a spring-controlled hammer, O, which is pivoted to a standard, Q, erected from the bed-plate of the apparatus. Thehammerbelow its fulcrum is provided with two arms, O O2, one of which, O2, is hooked at its extremity and connected with a spiral spring, R, the upper extremity of which is linked to the one ot' the brackets g which supports the drivingshaft G.

Upon the driving-shaft is mounted a cam, S, which is set to encounter the arm O of the hammer, and which occasions the depression of said arm and the consequent tilt of the hammer backward and in position for striking, the blow of the hammer taking place a-t the instant when the further rotation ot' the cam causes its escape beyond the arm O ot' the hammer.

Vhilel have spoken of but a single hammer, one hammer is employed in connection with each head, and the hammers are so timed as to strike each chisel as the latter advances in the rotation ot' its head into the path of the hammer.

In order to operate the hammer which is employed with the head D, I have provided a hammer-shaft, T, similar to the driving-shaft IOO IIO

upon the opposite side of the apparatus,which shaft is provided with a cam, S', and is driven through the medium of a cross-shaft, U, and two miter-gears, V V', as will be understood from a reference to Fig. l.

The gearing of the driving-shaft G and hammershaft T is such as to impart to them an equal speed of rotation, and the cams which they respectively carry are so set upon them as to impart an alternate and not synchronousl actuation to the chisels, the chisels, which operate in connection with the twisting-hooks of a given head, acting to sever the loops successively at the instant that a given chisel of one of the heads comes in the path of the hammer, at which instant i that hammer, as stated, strikes said chisel. From the arrangement ofthe twisting-hook and chisels it will be readily understood that the hammers operate alternately. v

' Having now described the construction of an apparatus conveniently embodying my invention, it is proper for me to say that the adjustment of the several operative parts is readily determinable by the mechanic setting up the machine, and that it is, of course, essential to the harmonious operation of all the assembled parts that each operative part i should perform its function at the proper 'inslant. Thus it is essential that the guide feed-roll should present the wire at the proper moment, and `that the proper twisting-hook should be properly presented kto engage the wire; that said hooks should be rotated at the proper instant to twist theloop upon it; that the hammers should operate alternately to cause the cutting of the wire at the proper instant, and that the various members should occasion the operation of the feed-roll. The twistinghooks and the hammers should be so relatively disposed as to effectuate the above results.

Vhile I have described only certain specilic mechanisms and a certain fixed and determinate arrangement of the same, I desire it to be understood that I contemplate the use and application of various equivalent and allied devices'and constructions in the embodiment of my invention in practical forms.

lVhile I have represented and described the hooks as formed with chisel-edges, it is' yet obvious that they could be made without such edges, and act simply as anvils, against which the chisels alone would cut. I prefer, however, to make them chiseledged, as it imparts a better point to the resulting barb `of the wire. v

The barbed wire as it emerges from the apparatus. is zigzag and not straight, and requires to be pulled straight when it is reeled.

Having thus described my invention,Iclaim anddesire to secure by Letters Patent- 1. Ina machine for making barbed fencewire, the following instrumentalities in combination: first, two rotating heads provided with devices which are suitably operated to automaticall-y form loops upon wire; second, an automaticallyoperating feeding device for supplying wire to the looping devices of both heads; third, devices suitably operated to automatically cut or split open the loops, and, fourth, mechanism for causing the operation of the feeding and loop-splitting devices.

2. In a machine for making barbed fencewire, the combination of two heads rotating in parallel planes, twisting-hooks having chisel-V edges carried by said heads and disposed in alternate opposite series, means for occasioning the rotation of the heads, means for imparting predetermined rotations to the hooks, aguide feed-roll adapted to supply the hooks in alternate opposite series with the wire to be looped, means for operating the guide feedroll, Aspring-chisels for cutting or splitting the loops of the wire, and means for operating said chisels, substantially as hereinbefore set forth. 3. The chisel-edged hooks mounted upon a hollow spindle, a chisel free to slide within said hollow spindle, and adapted to act against the chisel-edge of the hook, means for imparting rotation to the spindle and hook, and

means for actuating the chisel.

In testimony whereof Ihave hereunto signed my name this2d dayrof July, A. D. 1883.
