SIDNEY M. STEVENS, OF DE KALB, ILLINOIS, ASSIGNOB OF ONE-HALF TO JACOB HAISH, OF SAME PLACE.

MACHINE FOR MAKING BARBED FENCE-WIRES.

SPECIFICATION forming part of Letters Patent No. 243,170, dated June 21, 1881.

Application filed September 16, 1879.

To all whom it may concern:

Be it known that I, SIDNEY M. STEVENS, of De Kalb, in the county of De Kalb and State of Illinois, have invented a new and useful Machine for Making'Barbed Fence-\Vires, of

which the following is a specification.

My invention relates to machinery for automatically manufacturing barbed fence-wires, and is designed to greatly increase the speed with which the Operation may be performed.

In the accompanying drawings, Figure 1 is a top or plan view of the barb-applying mechanism, showing the machinery for barbing two strands of fence-wire simultaneously. Fig. 2

1 is a side elevation of the same. Fig. is an end view of the same from the receiving end of the barbin g mechanism. Fig. 4 is a perspective view of the stationary knives for cutting off the barb-wire, the guides for the barb-wire,

the grooved riding-wheel,to be hereinafter described, and their method of mounting. Fig.

- 5 is a perspective view of the guide for delivering the two strands of barb wire to the twister, and Fig. 6 is an end view of the same.

Fig. 9 is a continuation of the same section down 0 through the wheel. It also represents a section on the line 3 y of Fig. 2. Fig. 10 is a top view of the clinching-jaws and their heads. Fig. 11 is an enlarged section of the upper portion of a pair of the clinching-jaws. Fig. 12

3 5 is a perspective view, enlarged, of one of the clinching-jaws. Fig. 13 is a face view of a portion of the great wheel within the rim. Figs. 14, 15, 16, and 17 are diagrams of the positions of the fence-wire and barb-wire in the groove at various stages of the operation. Fig. 18 is an end view of the completed double barb and strand, and Fig. 19 is a perspective of the same.

In the said drawings, A represents a suita- 5 ble frame-work, preferably of metal, and very the direction indicated by the arrow on Fig. 2, by means of the large gear-wheel B rigidly attached to the shaft B, meshinginto the pinion B on theshaft B, which carries the bandwheel B This band-wheel is the drive-pulley from whence the whole mechanism receives its motive power.

The present machine isconstructed to apply barbs to two wires, which are subsequently 6o twisted together to form a single cable, and hence the barb-applying wheel is furnished with two sets of barb-applying devices, only one set of which need be used in case a single wire is to be barbed, even where such single wire is to be twisted with an unbarbed wire. Therefore, in describing the barb applying mechanism,it will be sufficient to describe one set of the parts upon the wheel, with the explanation that these parts are duplicated on the same wheel, there being in the periphery of the wheel two grooves for containing the main wire, two rider-pulleys for compressing the main wire into the grooves, two sets of feed-rolls, one at each side, for feeding in the barb-wire, and two sets of pinching-jaws arranged at intervals for pinching the barbs on the main wire.

The wire-containing grooves in the great wheel are lettered b, and extend entirely around the periphery of the wheel. Arranged within this groove, at intervals, are steel pins I), having their upper ends flush with the bottom of the groove, and provided at their lower ends with a setscrew for setting them up as they wear 8 out by contact and friction with the barbs, which are applied at these points. In the machine shown in the drawings there are nine of these steel pins arranged at equal distancesfrom each other around the wheel. 0

The main fence-wire O is brought into the machine in the direction indicated by the arrow on Fig. 2, is passed beneath the tension-pulley G into a groove in said pulley, and, after being carried completely around said pulley, is 5 led from thence to the groovein the great wheel.

A short distance above the point at which the main .wire enters the groove in the great wheel is a rigid grooved rider-pulley, D, so mounted in acarriage, as will presently be explained, that too a kink or splice in the wire will throw it loose and permit the splice to pass. At all other times, however, said rider sets firmly down upon the fence-wire.

E Earefeed-rolls for feeding in the barb-wire F. These feed-rolls, or rather the lower one of the pair, is rotated by the gearing e e, (2' being on the shaft 0 which receives motion by the gearing e and c from the shaft 6*, which in turn receivesits motion bythebevel-gearin ge c from the shaft B The barb-wire F, led through an aperture, F, in the guide-piece F is passed between the aforesaid feed-rolls E E, and by their action is fed across the face of the periphery of the great wheel B into the angle formed by the periphery of the great wheel and the main wire 0 as it enters the groove b,passing just in frontof theknife b through the guide b (shown at Fig. 4,) whereit remains until one of the knives, 11 in the periphery of the great wheel, of which there are nine, comes around and severs the barbwire diagonally. The severed portion is caught by the main wire in the further revolution of the great wheel, and held against the periphery of said wheel by the pressure of the main wire upon it. The wire leading from the tension pulley to the groove bears such a relation to the contour of the great wheel that at the moment the knife on the great wheel encounters the barb-wire and severs it by contact with the stationary knife, the fence -wire' has commenced to exert a pressure upon the barb, so that by reason of the barb resting against the knife which has just severed it, and being subject to the pressure of the main wire, it cannot fall back or escape from being carried around by the great wheel. The barb lies now across the groove and is held from slipping in a direction reverse to the revolution of the great wheel by the knife b*, which has j ust severed it and which lies behind it. In order to insure the retention of the barb, the other end of the straight piece of barb-wire from which it is intended to form the barb lies in a hollow or depression in the clinching-jaw, presently to be described, located on the other side of the groove. Thus firmly held under the main wire and athwart the groove,in the position shown in Fig. 14, the barb is carried forward by the further rotation of the great wheel until it comes between the grooved rider pulley and the great wheel, whereupon the pressure of the said rider-pulley forces the main wire and the barb-wire into the groove, in the manner indicated in Fig. 15, formingof the short piece of barb-wire a staple. This staple, held in the groove by the main wire, as indicated in Fig. 16, is carried on by the further revolution of the great wheel until the clinching-jaw, which has been lying idle thus far by the side of it, is brought into action, and the two ends of the staple thereby forced past each other into the shape shown in Fig. 17, which shows the position of the clinching-jaws at the moment the barb is formed.

The clinching-jaws referred to are arranged in pairs, one at each side of the groove and at the same place in the wheel as the steelpins b heretofore referred to. One of these jawsthe one marked Gis stationary except so far as it moves with the wheel. The other one, G, is movable, being pivoted within the wheel in some cases, but in the instance shown in the drawings upon the spring 9, the action of which is to keep it away from the groove. The top of this movable jaw G is provided with a camhead, G which may, if preferred, bea roller. This head G in the rotation of the great wheel, encounters a wedgecam, G borne in the frame-work of the machinejust above the great wheel. A bottom view of this cam is given at Fig. 7. The operation of this cam is to force the jaw G out into the groove 1) against one limb of the staple. The edge, g, of the jaw G striking the staple close above the fence-wire, crowds the fence-wire across the groove 1) under the stationary-jaw G. The edge, 9 of the jaw G, in the meantime holds the other limb of the staple in such a manner that it is turned diagonally across the groove 1) into the inclined depression of jaw G. The two points of the barb now stand in the position shown in Fig. 17. The further rotation of the great wheel beyond the influence of the wedgecam G releases the barb by allowing the spring to throw the clamping-jaw back into its original position. In order, however, to insure this action if the spring shouldfail, I provide a returning-cam, G, which strikes the head upon the other side and forces it back to the required position.

Of course it will be understood that the operation just described is repeated for each pair of clamping-jaws, so that the machine shown in the drawings will puton nine barbs at each revolution of the great wheel, and there being two grooves, it will in fact put on eighteen single, or two pointed barbs, or mine four pointed barbs ateach revolution. From the two grooves the two single wires, now duly barbed, are led out into the troughsha-ped double guide H, the sides of which being inclined and acting upon the barbs as upon a lever, turn each of IIC the wires so that when the two wires meet each other the points of the barb upon each of the wires willstraddle the other wire in the manner indicated at Fig. 18; and the barbing devices in one of the grooves of the great whee], arranged to operate an instant later than the devices in the other groove, will prevent the barbs from interfering with one another when the wires are brought together-that is to say, the barbs are thereby caused to lie adjacent to instead of exactly opposite each other, whercby neither interferes with the crotching within its points of the wire carrying the other barb; or, by adjusting and timing properly the operation of the devices in the two grooves, so that they shall operate simultaneously, and properly adapting the guide H, the points of the barb may be made to interlock. I prefer, however, theothermethod. Thetwowiresthus barbed are brought together preparatory to being twisted, as shown at Fig. 19. The forward feed of the wires is accomplished by the friction thereon while they lie in the great wheel, principally that caused by the riderwheel. When released from the great Wheel they pass to a suitable reeling device, which may also twist them. I will now return and describe some of the details which were omitted for the sake of continuity.

The tension-roller G is provided with a pressure tension-lever, I, pivoted at i and provided with a set-screw, i, producing greater or less friction upon the roller, and thus regulating the tension upon the main wire. I

The upper feed-roller, E, is pivoted in a hinged lever, E hinged at m, Fig. 1, one end of which rests under a screw, E whereby'the tension of the feed-rolls may be regulated.

The grooved rider-pulley D is mounted in a frame, D, pivoted at D to the main frame of the machine. This frame D is furnished with a horn, D which rests againstaspiral spring, D, contained in the barrel D attached to an arm, D, on the main frame of the machine. A small notched lever, D, projects out below the riding-pulley D, and encounters with its notch the main fencewire, not, however, coming in contact with the main fence-wire except in case of a splice or knot in the wire. The lever D is centrally pivoted, and at the other end from the notch is jointed to an upright rod, D held up by a'spring, D which rests on the carriage D. This upright rod D constitutes a latch, which, resting against the main frame of the machine, holds the rider-pulley and its f1 ame rigidly against the fence-wire at all times except when a splice or knot in the fence-wire strikes against the under side of the lever D and by raising said lever releases the latch, thus permitting the rider and its carriage to yield backward against the spring D as the splice or knot passes under the lever D". After the splice or other obstruction has passed, the spring D returns the carriage and pulley to its normal position, where it is latched rigidly by the latch until another obstruction presents itself. This contrivance avoids the strain of running the splices of the fencev'ire under the rider-pulley, and prevents the difficulty which might occur if it were attempted to apply a barb at the splice, as the loosening of the fence wire, or, rather, the absence of the pressure of the rider-pulley,would cause the straight piece of barb-wire to ride over the great wheel unformed.

In order that the two sets of barbing devices upon the great wheel may be adjusted to operate either simultaneously or at aslight interval from each other, I make said wheel preferably in two parts, the line of separation of the two parts being indicated in Figs. 8 and 9, there being a groove and barbing appliances in each part. These two parts I secure together by bolts passing through slotted apertures, as indicated at'Fig. 13, the slots being circular and concentric with the wheel, so that by loosening the bolts one of the halves of the wheel maybe turned and adjusted. One of the parts is, of course, rigidly attached to the shaft, in order that both may be carried by it.

The stationary clampin g-jaws and the knives are all preferably provided with set-screws, whereby they may be adjusted.

It will be understood from the above description that the feed of both the fence-wire and the barb-wire is continuous, the great wheel cutting off and applying the barbs as fast as the feed-rolls feed the barb-wire in, the only timing necessary being the relative speeding of the barb-feed with that of the fence-wire. If the relative speed of the feed-roll E is increased, the result will be a longer barb if diminished, it will result in a shorter barb. When any change in this particular is desired, I move the gears by which the feed-rolls are operated so that they are actuated by the gear 0, which may be either larger or smaller than the gear 0 shown as actuating them.

Of course, it will be understood that both the fence and the barb wire, before being led into the machine,may be wound upon suitable spools or reels, which, however, are not shown.

It will be understood by those skilled in the art that, by the mechanism hereinbefore described, barbs may be applied at a much greater rate of speed than in any of the machines thus far in use.
