SPECIFICATLN forming part of Letters Patent No. 286,511, dated October 9., 1883.

Appnnmon med May 2G. lass. (No model.)

Be itknown that I', 'BH3-:onces A.. WEBERV ofthe city and county of .New York, in the State o f New York, have invented a new and Improved Machine for Making Barbed Fence- Wire, of vwhich the following is a speci-fica-A tion.

The object of my invention is to provide a machine for making barbed fence-wire, such as forms the subject of my application for Letters Patent filed May 3, 1883, and of which the serial number is 93,746.- The wire referred to consists of a longitudinal wire having formed in or Vfrom. it at intervals pairs of eyes, the eyes of each pair beingyopposte each other-that is, on oppositet'idesofthe line of the wireand barbs consisting of short wires, each inserted through the eyes of a pair, and having its sharpened. ends projecting beyond the eyes in opposite directions. This wire, provided with barbs,-niay. be employed alone for fencing; or

' it may be, and preferably is, twisted with another longitudinal wire, which prevents the wire having the pairsfr-om being strained to such an extent as to draw outor distort the eyes and displace the' barbs from their position at right angles to the longitudinal wire. Iii-my machine is performed thewhole operation of forming the pairs of eyes, formingand securing-the barbs therein,and twisting the two-longitudinal wires together.

`The invention consists 1n novel features in the construction of the several parts of the machine, and in the ina-nner of combining the said parts together to provide mechanism for feeding the Wire forward with a step-by-step movement, and for giving the proper dwell between such movements; for vforming the pairs of eyesin the longitudinal wire; for feeding wire and cutting it off to the proper lengthto form barbs; for bending' such pieces of Wire into the form of staples, or giving them a U shape; for' inserting such staples or U-shaped pieces into the pairs of eyes, and spreading or bending outward the ends thereof which project through and beyond the eyes, so that they will project in opposite directions, and thereby be secured in the eyes; and, preferably, for twisting the wire thus provided with barbs 4with a secondlongitudinal wire, as above mentioned.

'formed by the several op@ chine can be obtained from Fig. 3. I

In the accompanying drawings I have illustrated a machine embodying my invention.

A clear conception of the work to be pertions of the ma,

"A designates the longitudinal wire, in` or from which pairs of eyes a c are formed at suitable intervals or distances apart.

. A designates the barbs, lwhich'are inserted through the eyes of each pair and have their sharpened ends projecting in opposite directions. 'Ihe Wire A,with its' barbs, may be used for .fencing purposes; or it may be twisted with a second longitudinal and plain wire, A2, asshown in Fig; j

Referring now to the machine, Bdesignates a bed or frame of considerable length. At one end thereof is supported the mechanism for forming the eyes andv forming and applying the barbs, and at the other endther'eofjs a iiier or twisting device for twisting two longitudinal wires together. n'

C designates the main or driving shaft, to

which motion may be imparted by abelt pass-4,

ing around a pulley, C Y

D designates a vertical shaft receiving modcsignates a transverse counter-shaft receivvtion by bevel-wheels b from the shaft C, and E `of swinging'slightly on the ing motion through bevel-wheels bb' from the said shaft G. By means of these three -shafts motion is imparted to all the operating parts of the machine. The wire A is taken from a reel or drum, c, at one end of the machine, and is drawn forward between two wheels or rollers, d d, which have their peri pheries grooved to form a channel for the wire. These wheels or roll'ers serve to direct the wire as it is drawn off different points in the length of the drum, and also to produce a friction or tension to hold the wire back. They may hc'made to grasp the wire more or less tightly by adjusting-screws applied to their bearingsl in a wellunderstood manner.

E designatesa feed wheel or roller,whieh is secured upon a rotary shaft, d', and has aperipherical groove, in which the wire A rests. The shaft d has secured upon it a ratchetwheel, di, with which engages a pawl, d.

, This pawl is carried by a crank-pin, (Z, onthe end of the shaft E, and by it a stcp-by-step rotary motion is imparted to the wheel or roller E. A stop-pawl, d, engaging with the ratchet-wheel (F, prevents backward or return movement of the feed-wheel E. In the pcriphery of the feed-wheel E arc notches d, which are placed at a distance apart equal to the distance between the barbs A', and the notches engage with the barbs and ,serve as teeth to draw the wire forward positively after the barbs are secured to it.

Between the di reeti ng wheels or rollers d d and the feed-wheel E is arranged the apparatus for forming the pairs of eyes a a and for forming the barbs and seem-in f them in said pairs of'eyes. The mechanism tor bending the wire A to form the eyesa is represented in Figs. l and 2, and upon a larger scale in detail in Figs.I 5, (l, 8,9, 10, and 11.

Upon the vertical shaft Dis fixed a gear whccl,c, -and upon the loosely ful'crumed a frame,

spursame shaft is which is capable shaft in a horizoncomposed of upper tal plane. This frame is and lower arms, e c, which are connected by a rod, c". In the arms e c'l is journaled a rotary shaft or spindle, F, which has x'cd or formed upon its upper end a disk, F, that ro- -tates with it. This disk may be considered as a part of the shaft, for it' the shaft were large enough no disk would be necessary. The shaft orspindle F is hollow, as shown in Fig. 5, and within it is a rod and downward within it. The rodqc passes through a nut or plug, e5, screwe'd into the lower end ofthe hollow shaft F, and' near its'upper end is a collar or head, @"from which two pins, ci, project upward through and above the disk F. The two pins form a twisting-fork, and their distance apart is just equal tothe distance apart of the cyesa of each pair. The rod t" is normally picssed upward, so as to hold its pins c7 above the surface of the rotary disk F" by a Spring, e, in the hollow shaft F, which bears at one end on the 'collar or head or 'plung(n,- e', which is made to. rot ate w1th1t,but1sfrec toslide slightly upward c and `at the other end upon the nut or plug e". Upon the lower end of the rod c' is a flange or collar, e, on the upper side of which is a 7o projection, cl", and in the circular path described by this projection is a fixed cam, c,

on the lower arm, ci. Once during each .rotation of the shaft F and disk F' the projection ew comes in contact with the fixed cam e and 75 draws the rod e* down suiiciently to shcathe the pins ci ortwisting-fork b'elow the upper surface of the rotary disk F. Immediately on the projection c passing the cam c, the spring d* again raises the rod e" and projects its pills So above the surface of the disk F.

Upon the hollow shaft F is secured a spurwheel, c"-',\vliieh gears into and receives motion` from t-he wheel c on the shaft D. These wheels being of the same size, the shaft C, the shaft F5 1 and the shaft F and twisting-disk F all rotate in unison.

Upon 'the upper surface of thcdisk Farc two inclined projections, e, and on the periphery ofthe disk is a projection or cam-like lug, c, 9o the purpose of which will be hereinafter described.

XVhcn the pins eT are projected upward by the spring c", they are in such a'position that they straddle the wire A, or receive said wire 95 between them, and as they move with the rotary disk they come against opposite sides of the wire, as shown in Fig. 8, and bend it. Fig. 10 shows the wi re after the bending operation has progressed considerably. Fig.l 9 1c. shows the wire after the bending,r operation has progressed still more, and Fig. 1l shows the wire alter the bending operation is almost completed and shortly before the vpins e7 are drawn down bythe action of the pro- 105 jection eo'on the cam c". Before the pins are drawn downhowever, the eyes a. a are brought into position opposite each other and in a line directly across the wire, as shown by the Icompleted pairs of eyes a o, Figs. S no and 9. \Vhen the two uncomplcted. eyes are brought into the position shown in Fig. 9, it is necessary to raise the wire before and behind the pins, so that the eyes will be carried under such portions of the wire, and this is 1x5 effected by the inclined projections c, which are, shown in Figs. 6 and 9 as in action, and which raise the wire up, so that the incomplete eyes pass under it. W'hcn the bending operation to form the eyes is just` about to eon1. 12o mence, and the pins e7 are in the position shown,l in Fig. 8,. the inclined projecticmscipass firstI under the wire. This is not objectionable, although it serves no useful purpose; but it is unavoidable, because two projections set diax25, metrically opposite to each other are used.l Just as the eye-formi ng operation is completed and they two eyes are brought into a line direct! y across the wire, the pills c -are drawn down out of the eyes which they have formed, x30 and at this instant the feed of the wire commences, and it is drawn forward to carry the pair of eyes beyond the disk F', and to bring a fresh portion 'of the wire in position. to be I escom 3 .wire is required in forming the pairs of eyes,

and as the wire in advance ot' the pins kL7 is firmly held by the fccd'wheelll, it cannot beA drawn back. lThe Surplus, therefore, must all come from the portion of wire behind the pins cpthat is, from the reel c. The pins c7 draw, lmwever, from both directions, and hence itis necessary that the mechanism for tbrniingthe eyes should be moved bodilyforward a dis' tance equal to halt the surplus required. .lhe swinging frame c c" e, on which the shaft F is ,journaled,provides for such forward moyement of the eye-forming` mechanism, and ll produce such forward increment and return movements by means of a wheel,` c, gearing wi-th the wheel c, journaled. on astud `lined in the frame li, and carrying a crank-pin, e",whieh is connected by a link, e, with the rod c of the swinging frame. The said frame is therefore ibrated siightly forward and back\\"ard,whilc the shaft F and disk l1" are rotated. After each pair of eyes are formed, the wire A is fed forward by the wheel E a distance, su llieient to bring the' pair of .eyes last formed opposite the mechanism for forming; and inserting the barbs A', which I will next describe.

'lhe barbs A are `formed from a wire, A, which is taken from a reel or drum, f, at the side of the machine, and passes between feedrollers j", which are g ared together by wheels .sand feed it forward ina direction transverse totlieline ofimwement ofthe wire A. Cihefeed-A rollers f may be nmde togfrasp the wire with sutiieient tightness by means of adjusting:- scrowsfupplied to the'bearing's of one ofthe rollers, as shown in Fie. 4. Upon the shaft ofone of the rollers is aratchet-w heel, f", and designates a pawl which is formed upon or attached to :in eceentric-rod, (i, which is ciproented by an' eccentric, on the shaft'. O. ly the feeding-rollersj/ thowire A is moved step by step, at. each step n distance equal to the length of a barb. Figs. Al, 5, t,A and 7 best show the mechanism for forming` and inserting' the barbs. 1

The shaft E is jonrnaled in an upwardly extending portion of the frame B, as shown in Fifi'. 4, and in across-bar or portion, B', of

this .frame is a compound punch, which consists of en inner plunger, H and an outer annular plunger, Jti/,both arranged directly below the shaft lf). lThe frame portiou has an annular eountersunk hole or bore, g, which ref eeives the onteiplunger, ll, and the latter is maintained normally in an elevated position, unless otherwise acted upon, by'a spring, bearing cuits upperend on a flange or shoulder, (12, on the plunger il", and at its lower end on the bottom of the eountersink which receives the plunger.. rlhe said outer plunger, li', has a eountersunk hole or bore, y, which receives the plunger l'l, and the hitter is normally maintained in an eierated position by` a spring, g, bearing` at itsv upper end on a shoulder, gf,.on the plunger l l', and at it'slower Agiving each barb sharp points at end on the bottoni of the countersink in thev The two plungcrs can be pushedplunger H. down independently of each other, and are returned by the aforesaid springs.

U ionthe shaft Eisaeam h whiehaetsu on l a i and serves to depress the inner pl unger-` H, and at cach side of said cani are cams lf, which are of similar forni and act on theouter plunger, Il', to depress it.

I designates a swinpingurm fnlerumed at h above the sha'l't IC, and having projectionsl1", which bear on the cams Il. '-lheselatter cams therefore serre the double purpose of operating' the outer plunger, ll', and. imparting' a swinging' motion to the arm l. '.lhis arm isili the saine vertical plane as the plungers 1I ll, and it may swing;` int o the position shown in Fie'. 5, so that its end portion will be directly under the phnngers ll ll', or into Jthe position shown in Fig, ti, so that its end will be entirely' ont of thc way of the said two plungers. The barb is bent into an inverted-U shape by a peculiar formation ol' the. lower end of the plunger ll', actin;y in conjunction with the swinging` arm l. ln the lower end of the plunger il' is formed a notch, if, which is in the same plane as the swinging` arm Landwhen theplunger lIll is pushed down, as shown in Fig. 7, it strat'ldles the point portion 1i of the arm I, the latter being` received into the aforesaid notch 1".

For cutting: off the'wire A, l employ shearbladesjj, the former of which is fixed to the frame B, as shownv in Figs. 4 and 7, while the latter is secured to and moves with the plunger ii, and operates, in conjunction with saidv fixed blade, to cut oll'the wire diagonally, thus both ends. Nhen t-he pair of eyes d a last formed are brought forward by the feeding: operation of lthe wire A., they are :brought directly under the center of the plungers H ll', and at the same time a suiiicient Ylength of the wire A has been fed forward beyond the shear-blades cams h now allow the swinging arm I to inoyc forward under the barlrwirc A, and the end `il of said arm isor may be inclined, as shown will readily pass` lunder ,the projecting portion of the'wire A in Figs. [i and 6, so .that it and not strikeagainst it. The plunger H^ now descends, and its tirst function is to eut oit the wire A by the aetionof theblade jf upon it, in conj unetion with' the fixed bladej..

of the plunger H comes upon the cut-od' p0rtion, and,continuing its downward movement, bends tl e said cutoff portion down over the end 'i' o theY arm I and brings it into the former 'i' in the position which they occupy :it

of this U-shaprd barb are the same distance apart as the eyes a of each pair in the wire A. \Vhilc the cams h still hold the plunger' `H down, they act, ou the projections Irl of the' swinging arm or former I, and move it out- 'ai-d, so as to withdraw its point from the staple-like or U-shaped barb, and at the same time-the cam h forces down the plunger' H, so that it. presses on the top of the staple or U- shaped barb, and forces it 'downward out of.

portions, which engage and cause the spread' ers to swing or move simultaneously, but in opposite directions. l The spreadcrs are furnished withtbrwardlyprojecting horns or arms I; which norma-lly lie close together. as shown iu Fig. S, and-these horns oearnis forni a rest over which 'the wire A passes, and upon which the pairs of eyes come to a' stop in the position shown in Iiig'. S. are projecting lugs or ears m m', which projeet in `the cireulznpath describedgby th'cfproiection (Non 'thedisk` Fi *WVliile the horns or arms l of the sprcaders .T are together, as shown in Fig. S, the staple-like or U-shaped barb has been driven down into the pair of eyes t by the action ofthe plunger ll, and the horns or arms l t'orm a bed or rest for the wire A during theoperation. After passing through the eyes u, the barb passes down and st raddles the horns or armsl, the ends ofthe barb heilig on opposite sides of the pair of horns. .lust at this instant, the lugl' or projection el* on the rotary disk h" strikes the lug;` or projection in on one of the spreadcrs J, and turns the spreaders on their pivots, so as to move their horns? .in opposite directions, or spread them into the position shown in Fig. tl, and thereby the two ends ot the. -barb A' are spread outward, so that they will project; in opposite directions. ])uring this spreading operation, the plunger l l' has retained its pressure on the top of the barb, and has-prevented it from rising, as it otherwise. would do. lly this method of holding and spreading the bai'lylinake it bind in and acrossbetween the eyes and scenre. it `very :firmly in the eyes. so that it will be rigidly held and cannot shift 'and become loose, as the. barbs in many kinds of barbed wire. now do. After the projection c" passes the lngr m, it strikes the lug m' and swings the spreaders .l in the opposite direction, sp as tov again bring.;v their horns together. ly this time the forward movement ofthe wire A has taken place, and moved the pair of eyes wherelpon the spreader-si' in the barb is secured out; of the way and brought another pair of eyes into position to receive a barb. The wire having the barbs secured as described may be 'taken from the 7o feed-wheel E and reeled up, and will form aA strong and desirable fencing material. lIt may be conducted through a galvanizing-bath, and

it will be thereby galvanized throughout, even to the cut ends 0l' the barbs. After being gal- 75 vanized, it may be twisted with the plain galvanized wire A2.

L It is impractieablc to pass barbed-wire fenc- '5 ing i n which two longitudinal wires are twisted together through a galvanizing-bath, becausel 8o the galvanizing metal will lodge and adhere in great quantity to the twisted wires. Therefore the barbs in fencing ot' this character have nothad their cut ends galvanized, and were liable to injure cattle by reason of the rust 85 lodging in the scratches or wounds inflicted by them. .l am enabled to galvanize the wholewire after the barbs are secured, because but a single wire is employed to secure the barbs.

ln the machine here represented I have 9o shown mechanism l'or twisting the wires AA together.

At the end of the `machine at` which the barbed wire is delivered there is a tiier, K, n'iouuted on a hollow spindle, 'K'. On the'g5 spindle is a pinion, il, which receives motion from. a whe'eh'af, on the shaft C. '-,In the hollow spindle 1i is a shaft, lig. on the inner end -otf which is fixed a pinion, n2.

L designates the bobbin orreel, on `which Ioo the completed twisted wire isjvound. It carries a friction-wheel, i12- which receives motion from a friction-pinion, n. The pinion n is capable of rotating on av stud withv a pinion, u

of', and receives its motion by the gearing of 105 the pinion n5 with 'the pinion 11". The -inner shaft, li", carries a wheel, n", which gears with and receives motion froma pinion, nl, on theshaft C. By this' mechanism the flier is rotated to twist the wires Anf, and the reel L I 1o is rotated to take up the twisted wires. The

vbarbed wire A lpasses from the feed-wheel E' under a rolleror wheel, o', tothe rollers 0'o,'.

which arc-slotted or composed of pins, and

which form a nipper, and thc'gwlre A2 passes H5,

from a rcel, o. over a roller or wheel, o, and thence to the nippcr o o. The twist takes place between thetwo guide rollers or wheels o o and the rollers o e, forming the nipper. I
