MACHINE FOR BARBING WIRE.

SPECIFICATION forming part of Letters Patent No. 273,286, dated March 6, 1883.

I Application filed December 27, 1882. (No model.)

To all whom it may concern:

Be it known that I, ALLEN JOHNSTON, of Ottumwa, VV-apello county, Iowa, have invent'- ed a new and useful Improvement in Machines for Making Barbed Wire, which improvement is fully set forth in following specification,

The invention yhas reference more particularly to machines for making barbed-wire fencing, in which the wire for making the barbs is carried by and delivered from a revolving support turning around the strand-wire, instead of from a stationary support at the side of the strand-wire, although it is in part applicable to other kinds of machines. v

It comprises a barb-applying mechanism operating on a new principle, animproved feeder for the wire for making the barbs,or the barbwire,77 as it will be hereinafter called, a new barbing-clamp, and a strand-wire feeder for aiding in the application of the barbs and for advancing the strand-wire, and also'certain special constructions, combinations, and arrangements of parts in the machine.

The object of the invention is to make a simple rapidly-operating machine, not liable to get out of order, and efficient in the application of the barbs.

The new principle of operation in barbing is the holding of the free end of thc barb-wire and the wrapping of the said wire from its.

crossing with the strand-wire inward toward the body of the wire bythe revolution of the spool or body of barb-wire around the strand-wire. After the wrapping, the barb is severed from the body of the wire. Heretofore the barbs have been severed from the body of the barb-wire after application to the strand-wire, but in all such cases, so far as I am aware, the free end of the barb has been wrapped around the strand-wire, so that the A number of revolutions of its support, according to difference in velocity of said support and the said cani.

The new barbing-clamp comprises jaws arranged to hold the end of the barb-wire and to clamp it against the strand wire. The strand-wire feeder comprises jaws mounted on a slide and adapted to clamp the strand-wires and advance the same. By mounting thejaws ot" the barbing-clamp upon the slide they will serve the double purpose of holding the barbwire in vbarbing and advancing the strandwire a-t'ter the application and severance ofthe barb.

The other improvements, including the manner of combining the foregoing into one machine, will be hereinafter specified.

The accompanying drawings, which form a part of this specification, represent a barbedfence machine constructed in accordance with the invention.

Figure lis a central longitudinal vertical section, partly in elevation; Fig. 2, a plan; Fig. 8, an end elevation; and Figs. 4 and 5, vertical cross-sections of the machine on lines xx and y y, Fig. l, respectively. Fig. 6 is a development ofthe cylindrical cam for advancing the strand-wire, and Fig.y 7 an elevation of the cani for feeding the barb-wire.

. A is the machine-frame, by which the other parts are supported directly orindirectly. The hollow spindle B, the cam-shaft C, and the rock-shaft Dare journaled in bearings, and the slide E is mounted in ways in or on said frame, and the bracket F is bolted thereto. The barbing-head G is made in one piece with the spindle B by casting or otherwise, or it is fastened thereto. It revolves with said spindle. It is provided with a barb-wire holder and guide, H, through which the barb-wire is delivered, and by which the said wire is carried around the strand-wire. As shown, the holder and guide is formed by a ring or washer bolted to the head; but it may be otherwise formed. The ring or washer has a hole drilled obliquely through it for the passage of the barb-wire. Near its circumference the head is made hollow to receive the coil I of barb-wire, which is wound in the space circumferentially-that is, it is wound upon the body of the head as on a spool. The coil is supported upon antifriction rollers K, to allow it to be IOO the spring-plate N and slide L, which form the jaws of a clamp, through a hole in the pin M, and thence through the holder and guide H. The slide L heilig moved by the cam P, as eX- plained below, toward the center or axis ofthe head, the clamp holds the barb-wire and draws a certain length of it from the coil I, and feeds volve with the head.

thesainelength through theholderandguideH. When it is moved back away from the center the end of the barbwire is held stationary by means described below, and the clamp slips over the wire. The ends of the spring-plate N are preferably notched to tit over the wire, as shown in Fig. 5. The barb-wire is either placed on the head, as a coil already made, or it is wound into the head. llhe construction of head shown admits ot' either mode of proceeding. The annular rim Q is separate from the body of the head, and is held in place by overlapping i'langes and screws. The flanges hold the rim from movement in one direction and the screw-heads from movement in the other, while at the same time the rim is leftV free to turn on the body of the head.

By removing the screws, the rim can be taken oft', a coil ot' wire put in, and the rim then replaced. It may be said, however, that, as shown, the other parts ofthe machine are not adapted to permit the removal of the rim. It is, in fact, deemed more advantageous to wind the wire into the head. For this purpose the periphery ot' the rim has a hole or preferably a cross-slot, It, through which the Wire is passed, one end of the barb-wire being held, say, between the vspring-plate N and slide L. The revolution of the head G will wind the wire thereon. During the winding the rim is kept stationary, but when all the wire has been drawn into the rim it is allowed to re- Ihe periphery of the rim, being closed, prevents the last end ofthe wire heilig thrown out by the centrifugal force. It' the wire end were otherwise secured, there would be no need of closing the periphery, and the periphery being open across the entire width or partially there would be no need of a separate rim. Flanges integral with the body of the head could be used to retain the wire in position. The wire can be wound into the head before the barbing commences or while the barbing is progressing. The barbing-head and its spindle are revolved by a belt on the pulley S, or by other appropriate means.`

The slide L is reciprocated by the grooved cam P, the pin M fitting into the .groove in the inner face of said cam, or face adjacent to the gears could be substituted without altering the principle of operation. The difference in the relative velocities depends upon the number ot' turns the barbs are to have around the strandwire and the shape of the cam l?. In the mai chine represented, the cam makes two revolutions to three ofthe head, and has two reverse inclines-to wit, at 1 2 3 a gradual incline, and at 3 4 1 a sharp incline. Both the head G and the cam P revolve in the direction ot' the arrow, (see Fig. 7,) and the pin M, which is carried by the head, will therefore in each three revolutions of the said head makea complete circuit of the cam-groove in that direction, and will pass successively t-he points l 2 3 4. lhe said pin aifd the slide L, in which it is fixed, will therefore by the incline l 2 3 be moved gradually outward toward the periphery of the barbing-head during two and one-half revolutions, or thereabout, (which is while the barb-wire is wrapping around the strandwire,) and will then in thereinaining half-revolution be moved by the incline 3 4 1 rapidly toward the center to feed the wire, ready for wrapping a new barb.

Itis obvious that the shape of the cam, the number of reverse inelines, and the differential veloeity can be altered within Wide limits. The slide could be made to pause at the end ofits stroke in eithei` direction by makinghe cani ofthe proper shape.

1n the interior ofthe hollow spindle is a non` rotating strand-wire holder, Z. It comprises a tube screwed at its outer end (right hand, Fig. 1) into the bracket F, and a tip, A, screwed to the inner end of the tube. 'lhe said tip A is supported and centered in the head G by the loose ring B andthe barb-wire holder and guide H.

In the bracket F is a brake for applying friction to the strand-wire. It comprises the spring C,the follower D,and thenut E. Thespring presses the follower against the nut, so that they clamp the wire between them. The follower has a projection, F', passing through the nut. By pressing upon said projection the follower may be moved down to release the wire. The nut E can be adjusted to center the wire in the tube.

The gear X is keyed or otherwise fastened to the cam-shaft C, sothat the said shaft derives motion through it and the gear W from the spindle B. In the machine shown, the camshaft makes one revolution to three ofthe spindie; but this proportion may be varied.

0n the shaft O are keyed or otherwisev fast- IOCJ IlO

ened the cams G'H'l'. Thecam H' is a drurn grooved on its periphery. The pin K', tapped into the slide E, works in said groove, so that by the revolutions of the cam the said'slide is reciprocated in its ways. The preferred shape ofthe cam-groove is shown in Fig. 6- that is to say, it has two reverseinclines and a straight portion-,so that the slide is reciprocated once in each revolution, and is made to pause at the end of its stroke. Of the inclines one is composed of a member, 56,with gradual slope, (so as to move the slideslowly,)anda second member, 6 7, having a steep slope, (so as to move the slide rapidly,) while the' second incline, 7 8,

vhas a steep slope, (so as to return the slide rapidly.) Between 8 '5 is the straight portion. llhe cam revolves in the direction of the arrow, and moves the slide outward, (to thele'ft, Fig. 1,) slowly at 1irst(while the barb is applying) and then rapidly, (to feed the strandwire,) and then retnrnsit quickly for a newoperation.

Journaled in bearings in the slide E are twov rock-shafts, L' M', carrying clamping-jaws N' at their inner ends, and geared together by sectors P' at their outer ends. A depending arm, Q', on the rock-shaft M', bears atits outer end upon the periphery of the cam 1', and itis also connected by the spiral tension-springR' with the pin S', iixedin the slide. The cam l' has its periphery notched at 10. (See Fig. 3.) When the notch comes opposite the end ofthe larm Q' the spring R' draws it into the notch and turns the rock-shafts L' M' so as to separate thejaws N'. The faces of thejaws should be slightly recessed to receive the strand-wire and the barb-wire, so that they take firm hold of them. The rock-shafts and their accessories are carried back and forth with theslide E.

The cam l' is made broad-faced, so that it is always under the arm Q'. The cams l' H' are so fixed in relation to each other that the notch 1U is under the arm Q'whiletl1eincline 7 8 moves over the pin K'. The jaws have therefore the following four successive motions, to wit: Being closed, they are moved outward, (to the left, Fig. 1,) carrying the wire with them; they are opened, releasing the wire; they are returned inward without the wire, and they are closed to clamp the wire between them.

Upon the rock-shaft D is keyedor otherwise fastened the cutter-frame T', one arm of which rests upon the cam G', while the other arm carries the knife or cutter U', which severs the barbs from the barb-wire. The cam G' is Vnotched at 9 to allow the cutter to come into contact with the barb-wire. The weight of the A cutter-frame tends to make it drop when released by the cam G', and, as shown, this'tendency is assisted by the tension-spring W'.

The holder and guide Hfor the barb-wire cti-operates with the knife or cutter U in severing the wire. The barb-wire being delivered through an oblique hole in said holder and guide, the edge of this hole which is farthest from the knife or cutter U at the time of severing the barb-wire acts as the second cuttingedge of a pair of shears, of which the edge of the knife or 'cutter U is the first. I

Having thus explained in detail the construction and operation of the several parts of the machine, the operation as a whole will now be described.

The follower in bracket F being depressed, the strand-wireis inserted through the bracket F, tube Z, tip A', and is thence passed between the jaws N' and carried to a spooler (not shown) of any ordinary or suitable construction. The end of the barb-wire is passed downward between the spring-plate N and slide L. This may be done beforeor after the head has been iilled with the'Abarb-wire, as before indicated. will be wound vinto the head as the barbing proceeds. Power being applied to the pulley S, the spindle B and cam-shaft C, with their cams and gears, are rotated in the direction of the arrows. As shown, the slide is at its inmost point, having 'fed down the barb-wire across the strand-wire, and slightly oblique thereto. The slide E is at the inner end of its stroke. The jaws N' are closed upon the strandwire and the projecting end of the barb-wire and press them together. The cutter or knite Uis raised away from thebarb-wire. The continued revolution of the barbiug-head wraps the barb-wire around the strand-wire, the wind-.

ing proceeding from the point of crossing with the strand-wire toward the body of the wire. As the wrapping advances the slide E is withdrawn enough to allow the several coils to be laid closely side by side. The supply of barbwire for wrapping is drawn from the coil I between the spring-plate N and slide L. These parts act therefore as a tension upon the-barbwire and cause it to be wrapped evenly and tightly upon the strand-wire. Just before the barbing-head has finished wrapping the barbwire around the strand-wire the cutter-frame is released by the cam G and drops, bringing the knife or cutter U' in the path of the barb-wire. The latter, by further revolutions of the head, is carried against and across the knifes edge and is severed diagonally, leaving the barb attached to the strand-wire, while the body of the barb-wire continues its revolution with the barbing-head. While this has been happening the slide has been drawn back or outward, ready for a new feed. Immediately upon this severance ofthe barb-wire the slide E, with the strand-wire and attached barb, is moved rapidly away from the barbiug-head, drawing a new length of strand-wire th rough the bracket F and strand-wire holder Z A'. Simultaneously the slide L begins to move inward to feed the end ofthe barb-wire across the strandwire, the jaws N' are opened, they, with the slide E, are returned, and so soon as the feed of the barb-wire is complete theyresume their hold upon the wires, the slideE being for the time stationary. The same cycle of operations is then repeated indefinitely.

The machine shown barbs a single strandwire. By introducing two or more strand- If before, then the barb-wire IOS IIO

wires, twisted or otherwise, through theholder tomatio feeder for the barb-wire, automatic Z A' it will apply barbs thereto in the same manner. No material alteration will be necessary. It' it be desired to have one end ot the barb thrust between two strand-wires, the strand-wire holder may have two separate openings in the tip for the two strand-wires. The strand-wires lnight be relied upon to hold fast the end of the barb-wire. The machine maybe adapted to apply two or more barbs simultaneously. Various other lnodications could be made without departing from the spirit of the invention. Those just indicated are not claimed herein, except as the modilied machines embody principles of operation or ot' structure in common with that shown.

The specific modifications may form the subject of separate patents.

The single-strand fencing shown in Fig. l may be used with or without other Wires. It is designed, however, to twist with the barbed strand a plain strand in the manner and by the means well known to those skilled in the art, or by any suitable means.

Portions ot' the invention may be used separately. Parts of the machine shown without materially altering their construction or individual operation could be used in machines having as a whole a diiferent operation from that described, and similarly the parts ot' the machine may be altered without material change in the general principle of the machine. A revolving support for the barb could be obtained Without employing the barbing-head as a spool-as, for example, a spool mounted on some other part of the spindle.

Instead of a cam and clamp for feeding the barb-wire, other devices, equivalents thereof, could be used-such, for example, as mutilated gears and feed-wheels.
