WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,653, dated February 15, 1887. Application filedNovember 23, 1886. Serial No. 219,598. (No model.)

To an whom it may concern.-

Be it known that I, ALBERT J. Barns, a citizen of the United States of America, residing at Joliet, in the county of tVill and State of Illinois, have invented'cert'ain new and useful Improvements in Wire-Barbing Machines, of which the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to certain improvements in wire-barbing machines, the construc tion and operation of which are fully set forth and explained in the following specification and claims, reference being had to the accompanying drawings and the letters and figures of reference markedthereon, which form a part of this specification.

Referring to the drawings, Figure 1 is a perspective view, taken from one side of the machine, representing the machine as it appears Fig. 3 is a detailed brokenaway portion of the machine, looking at the corner thereof, as indicated by arrow 1 of Fig. 2.

upon which the gear supporting the rotating cutters of the machine is'arranged,and through which the barb-coiling head is eccentrically arranged. Fig. 16 is a face view of the head which supports the barb-coiling mechanism and the rotating barb-cutters of the machine. Fig. 17 is a central vertical longitudinal sectional view of the same. Fig. 18 is a detailed sectional view of the coiling-head of the machine. Fig. 19 is a face view of the same. Fig. 20 is a detailed sectional view of a portion of the coiling-head mechanism of the machine; and Fig. 21 is a perspective view of a section of barbed wire, representing a product of the machine.

Referring to the drawings, B represents the bed of the machine, supported on suitablelegs, M, which bed bears upon its upper surface the principal working parts of the machine.

R is the main drive-shaft, journaled in boxes B B and located at one side of the machine above the bed, asshown in Figs. 1 and 2. The end of said shaft next the twister T is provided with pinion G, which meshes with hollow pinion G of said twister, journaled in box T. The opposite end of said shaft is provided with the pinions G2 G, which pinions drive the barbing parts of the machine. The extreme rear end of said shalt is provided with the crank-disk I, for driving the barb-wire feed.

H is a standard-box secured to the upper face of said bed, and is formed as shown in Figs. 2, 12, 16, 17. This box contains the coiling-pinion G which meshes with pinion G, which drives it. The chamber 2 of said box (shown in Figs. 12, 16, 17) forms a box for the rear part of the hub of said coiling-pinion, as shown in Fig. 12, and is long enough for containing a coil-spring, S, to yieldingly press said coilingpinion forward. A face-plate, h, secured to the face of said standard-box H by means of the bolts F, serves to secure said coiling-pinion therein, and forms a journalbearing for the forward-extending part of the hub of said coiling-pinion, as shown in Fig. 12. The chamber 1 in said standard-box containing said coiling-pinion has sufficient depth to permit a reciprocating movement of said coiling-pinion therein. Said standard-box H is cut away at one side, as shown at 1, Figs. 16 and 17, so the coiling-pinion can mesh with pinion G, as shown in Figs. 2 and 12 and in dotted lines in Fig. 7.

The plate his provided on its outer face with an extending stud, h, forming a spindle, upon which is placed the gear-wheel G, which holds the rotating barbcutters a and a, and which meshes with pinion G and is held on said spindle or stud by means of the extending side flange, g, of said pinion G as shown in Figs. 2 and 7. Said stud has an aperture passing through it longitudinally, forming the journal for the forward end of the hub of the coiling-pinion, which aperture or journal is eccentric to the periphery of said stud, as shown in Fig. 15. The forward end of the hub of the coiling-pinion (shown at G is reduced in size and screw-threaded, and O is a cap, of the same diameter, that screws on the screw-threaded outer end of said hub G, as shown in Figs. 11, 12,14. Said cap is reduced in diameter at its outer end, as shown in said figures, so it may not interfere with the stationary barb-cutter, as shown in Fig. 14:, and is provided with a central longitudinal aperture for the reception of the outer end of the strand-wire guide 0, and a similar aperture at the side of said first-named aperture for the reception of the reciprocating coiling-pin b. When the cap G is thus screwed on the end of said hub, it becomes a part thereof, and the threads in it and on said hub are turned in the direction so that when said hub rotates it tightens said cap thereon and causes it to rotate therewith, and also carry the reciprocating coiling-pin 1) around the strand-wires. The cap 0 is made removable, so it can be replaced when worn without having to substitute an entire new coiling-pinion, and also for the purpose of rendering it easier to replace said coiling-pin by another when necessary.

Figs. 7, 9, and 19 are face views of said cap. showing said apertures.

S is a reciprocating tube or sleeve arranged within the hub of said coiling-pinion, extending from the rear side of cap C through the rear part of standard-box H, as shown in Figs. 1, 2, and 12, and has secured on its rear end, by means of set-screw t, the stud D, bearing a through said friction-wheel, D, for engaging with segmentcam D on shaft R, by means of which cam said sleeve is reciprocated, as shown in Figs. 1, 2, and 12.

The coiling-pin b is located in alongit-udinal aperture through cap 0 at one side from its center, and attaches to reciprocating sleeve S by means of the notch b on its inner end, as shown in Figs. 11, 12, 18, and is reciprocated by means of said sleeve, which does not rotate. The cap (3, containing said coiling-pin, having been screwed on the hub of coiling-pinion G, as hereinbefore stated, really becomes a part thereof and rotates therewith, and necessarily rotates the coiling pin 11, both around said sleeve and the strand-wires passing through it, for the purpose of engaging the barb-prods to coil them around the strand-wires.

A removable strand-wire guide, C, passes so its forward end will be flush with the face of cap 0, and its rear end extends a little beyond the end of said sleeve and is held secure therein by means of a set screw, 15. This strand-wire guide is provided with a pair of opposite channels, 0, extending from its rear end to near its forward end, where they connect with apertures extending through its forward end, as shown in Figs. 11, 12, and 13. These channels and apertures are for the reception of the strand-wires \V V and guide them through the coiling-pinion.

The pinion G is provided with a pair of oppositely-arranged adjustable rotating barbcutters a and a, held in their proper places by means of the set-screws a and n, and are intended to shear with the stationary barb-cut ter a, seated in a channel in standard N, and held in place by cap-plate Q and proper capscrews, as shown in Figs. 1 and 2; and immediately back of said cutter a" is secured ablock, O,which serves to properly guide the barbprods past said standard N, and is adjusted by means of the set screw X.

N is an extension of standard N, and arranged at a slight angle with bed B, as shown in Figs. 1 and 2, and is provided with agroove at one side for the reception of the reciprocating head J, having a spring gripping-dog, d, and a gripping-block, d for gripping and feeding forward intermittingly the barbing-wire W. (See Figs. 2 and 6.) A small guide or eyelet, d, is attached to the extending part N of standard N, as shown in Fig. 2, and is for the purpose of guiding the barbing-wire Wto the grip block d. Said barb-feed is operated by means of crank-disk I through the medium of pitman P and lever L, as shown in Fig. 2.

At the time the barb-wire is first fed forward between the strand-wires the coiling-pin is withdrawn and the barb is fed forward to lie against the face of cap 0. As soon as the feed is complete the coiling-pin emerges and, in its rotation with the coiling-pinion Gflcatches the extending prod of the barb and coils it twice around the strand-wires, as shown in Figs. 14 and 21, the coil being made in the direction sleeve S, and is arranged therein ICC toward the coiling-pinion,which is forced back by said ,coil as it is made. As soon as the coil is complete the cam D through the medium of sleeve S,withdraws the coiling-pin within the cap 0, free from the barb,a-nd at the same instant one of the rotating cutters of the wheel G in conjunction with stationarycutter A severs the barb loose from the barb-wire VV' in a diagonal manner, to form the opposite prod of the barb, so that the barb will appear as shown in Fig. 21 when finished, and so that the next succeeding barb may be fed in across the face of the cap 0, as stated. Said coiling pinion is one-fourth the diameter of its drivepiniou G and consequently rotates four times the speed of said drivepinion for the purpose of rotating the coiler twice each time it coils on a barb. The Wheel G? rotates one-half way around while the coiling-pinion rotates four times-twice while coiling the barb and twice while withdrawnand a barb is fed in and completed at each half-rotation of wheel Gias it is provided with two oppositelyarranged cutters, aa, each of which severs a barb loose when they pass stationary cutter. a

The object of placing wheel G eccentrically with the coiling pinion, as stated, is to cause its cutters to pass near the strand-wires at the time the barb is severed loose and leave the prod the proper length, and so the opposite cutter on said wheel will be such a distance from the coiling-pinion as not to be in the way of the barb-wire when it is first fed in and belore it is coiled on the strand-wires.

In Figs. 18 and 20 a variation of the construction of the strand-wire guide 0 is shown. In orderto render it more easily made, the channels 0 may be continued through. its whole length. Its forward end may be diminished in size a little way back for the reception of the sleeve 0 on its diminished part, as

. shown in Fig. 20, the said channels being deep enough so the wires can pass in them through said sleeve 0 and the forward end, 0 of said sleeve can pass through to the front side of cap 0, as shown in Fig. 19, and said sleeve can have formed on it the annular flange S for holding'in the coiling-pin, as in the other construction; but when the parts are all connected the device is mechanically the same in both cases, the only advantage gained being that the guide can be made without having to bore the holes connecting with said channels.

\ In the construction of the barb-wire feed the outer end of the pitman P'is forked, as shown at P, Fig. 4, over a swivel-box, P through which the end of leverL passes and slides, and the lower part of said box is provided with a slide which traverses in the guideway E, secured to the end of the machine-bed.

Such construction prevents the outer end of the pitman from taking the curved motion of the lever L. The opposite end of said lever is provided with a guideway for the reception of a swivel-slide, L, connected with the sliding head J. Such construction permits lever 'too quickly when the L to reciprocate sliding head J in a straight line.

The disk I on the end of shaft R has pivotally secured to its face the plate I, by means of the screw V, at its lower side, and screw V, passing through slot V in disk I. The wrist-pin U is secured to the face of said plate I. By moving said plate I from side to side at the top the wrist-pin may be placed and held at different distances from the center, and thus change the stroke of the feed. Figs. 2 and 5 show this construction. The butterfly-wheel Z is journaled on the outer end of lever K, which is pivoted at its opposite end on stud Y of standard A and passes under cam E on shaft R, as shown in Figs. 1 and 2. When cam E rotates it will oscillate said lever and butterfly-wheel Z between the stationary buttei'liy whcels Z Z, for the purpose hereinafter stated.

S is a coilspring connecting said lever K Withthe fioor, for the purpose of preventing said lever and butterflywheel from rising cam E rotates, and for yieldingly holding said butterfly-wheel Z on I the strand-wires and preventing them from becoming slack.

Q is a loose pulley, ley, to which power machine.

In operation the strand-wires W W are threaded through the guide 0 in its channels 0*, and from thence over the two butterflywheels Z Z and under oscillating butterflyand Q is the drive-pulis applied to drive the wheel Z to the twister T. The barb-wire is intermittingly fed in, by the barb-wire-feeding mechanism described,diagonally under the cutting'edge of the stationary cutter A, and so its fedin point will pass between the two strand-wires far enough so its end fed in will be long enough to be coiled around thestrandwires the required number of times and leave a prod of suliicientlength uncoiled. The coiling-pin b then emerges, and in its rotation around the strand-wires catches the barb-point fed in and coils it twice around the strandwires in the direction toward the coiling-pinion, which is forced backward against the coilspring S at its opposite end by the barb as said coil is being made. At the instant the coil is finished the coiling-pin withdraws, and simultaneously one of the rotating barb-cutters, in conjunction with stationary cutter a severs the barb in a diagonal manner loose from the barb-wire. The oscillating butterfly-wheel then moves downward between the other two butterfly-wheels and draws the strand-wires along far enough for the next barb to be placed on in like manner. Whena barb is finished and moves on, the coiling-pinion is relieved from pressure of the barb and the spring behind it moves it forward and the coiling pin 1) reciprocates forward,by means of spring 8*, and emerges from the coiling-pinion after the next barb is fed in, and performs another like operation.
