To all whom it may concern Be it known that I, DANIEL Srovnu, a resident of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in \Vire- Barbing Machines; and I do hereby declare the following to be a full, clear, and exact deseription of the invention, such as will enable others skilled in the artto which it pertains to make and use the same.

My intention is an improvement in wire- O tob-r an, Iss5 SPECIFICATIONS OF'PATENTSO0TOBER 30, 1883.

barbing machines of the class adapted to form certain barbs in which the middle portion lies on the same side of and in, contact with the two strands of a fence-cable, while the ends are wrapped in opposite directions about the respective strands.

The invention is fully shown in the accompanying drawings, and described, explained, and claimedin the following specification.

In the drawings referred to, Figure 1 is a plan of the entire machine of which this invention forms a part; Fig. 2, a side elevation thereof, looking in the direction indicated by the arrow a, Fig. 1; Fig. 3, an end View of the driving mechanism of the wrapping-spindles, looking in the direction of the arrow a,

Fig. 1; Fig. 4, a front elevation (working size) of the front faces of the wrappingspindles and the barb-supporting cam and shaft K G; Fig. 5, a side elevation of same; and Figs. 6 and 7, plan and end views, respectively, of the barb formed by the machine shown.

In these figures, A is the bed of the machine, B the driving-shaft thereof, and B a side shaft connected with the driving-shaft by a pair of miter-gears. On the shaft B are rigidly mounted three cams, G G G, the first two of which, 0 0, press downward at each rotation the outer ends, respectively, of two levers, D D, pivoted on a shaft, F, which is journaled in bearings E, attached tothe bed of the machine. The inner ends of the levers D D are pressed downward by springs S S, attached to the under side of the bed, and the force of the cams, together with that of the springs, produces reciprocal vertical motion of the levers D D Near the center of the bed are two stationary bearings, I I, standing at an angle to eachother, and in these bearings rotate freely two spindles, J J, longitudinallyperforated for the passage and support of the two strands of the fence-cable to be barbed, and provided with wrapping-lugs T T in their front faces. The ends of the spindles project in rear of the bearings I I, and are provided with rigidlymounted pinions H H, and two vertical racks, L L, passing downward through openings in the bed of the machine, engage, respectively, with the pinions H H. Near the lower ends of the racks are pins which enter the divided ends of the respective levers D D and form a connection, by means of which the reciprocal motion of the levers produces reciprocal ver tical motion of the racks L L and reciprocal rotary motion of the spindles J J.

In front of the front faces of the spindles, and slightly below them, is a rod, G, lying in a line at right angles to the shaft B, and provided at its outer end with a crank-arm, b, whose free end is furnished with an anti-friction roller, 1*, which rests upon the cam G, and is raised thereby at each revolution of the shaft B. A spring, 0, attached to the rod tends to draw downward the free end of the crank b, and thus holds it in contact with the face of the cam, and the cam and spring co-operate in producing reciprocal rotation of the rod in its bearings N N.

The rod G is provided at its inner end with a lug, K, projecting upward from the rod and lying directly in front of the wrapping-spindles and slightly below their centerline. The upper edge of the lug is grooved in aline parallel with the rod G, for the reception of the barb-wire, as hereinafter described, and the position of the rod and lug and the form of the cam O are such that when the crank bis raised to its highest point by the revolution of the earn, the lug K occupies the position shown in Fig. 4 and by the full lines in Fig. 5; but when the crank drops to its lowest point the lug rocks forward to the position shown by the dotted lines in Fig. 5. The office of the lug K is to support the middle portion of the barb, to prevent it from bending while the ends are wrapped about the main wires. The ends of the barb being wrapped about the wires in opposite directions, it is the natural tendency of the middle of the barb to curve outward from the main wires; but the lug comes so near the lower surface of the wires as to leave only sufficient space for the barbwire, which is thusheld straight at its middle. The relative positions of the main wires, the barbwire, and the lug K are well shown in Figs. 4. and 5, in which J J are the spindles; dd, the main wires; (1, the barbwirc; K, the lug supporting the barb-wire, and T T the wrappingpins attached to the spindles. As is evident in these views, the lug K holds the barb-wire firmly against the main wire, and. prevents the middle of the barb from bending downward. As the lug swings forward, however, it drops below the line of the wires, and permits the finished barb to pass over it as the main wire is fed forward.

The operation of the machine is as follows: The barb-wire, being fed by suitable means across and under the main wires, is held in place by the lug K, as shown in Figs. 4. and 5, the wrapping-lugs T T being under the barbwire, as shown in Figs. i and The spindles J J are rotated in the directions indicated by the arrows in Fig. 5, and wrap the ends of the barb about the main wires, respectively, the barb-wire being severed in the meantime by suitable mechanism between the main wires and the barb-feeding mechanism. As they pass around the main wires the ends of the barb are carried through the space between the main wires and the faces of the wrappingspindles, and are turned outward in opposite directions on the lower side of the main wires. Immediately after the completion of the wrap the lug K rocks forward, the main wires are fed forward by suitable mechanism, and at the same time another barb is fed into position by the barb-feeding mechanism. The finished barb is in the form shown in Figs. 6 and 7, the feed of the main wires being in the direction indicated by the arrow in Fig. 6.

S13E01FICATIONS OF PATENTSOCTOBER 80, 1883.

The drawings show the barb-wire under the main wires and the lug K in position to support the barb-wire from belowg-but it is evident that it may equally well be placed above the main wires, if desired. It is also evident that the form and motion of the lug K may be varied indefinitely, so long as it has such a motion as will at onetime bring it into position to support the barb while being wrapped, and upon the completion of the wrap will so far remove it --as to permit the release of the finished barb. Since these details may be varied without changing its principle, I do not limit my invention to'the exact form shown here; neither do I wish to confine it to its combination with. the particular wrappingspindles or other devices included in this ma chine, for the supporting-lug may be equally well used with any machine making substantially the barb shown.

I am aware that the use of two wrappingspindles rotating in fixed bearings, standing at an angle to each other, is not new, since that device forms the subject of Letters Patent No. 243,683, issued July 5, 1881, to Bestor and Cunningham; and I do not, therefore, claim that as part of my invention.

In the drawings heretofore referred to no means for feeding the main wires or for feeding and cutting the barb-wire are shown, the ordinary and well-known feeding and cutting devices being used in this machine, and no novelty being claimed for them or any of them.

Having now described and explained my invention, what I claim as new, and desire to secure by Letters Patent, is

1. I11 a wire-barbing machine, the combination of two longitudinal]y-perforated spindles for supporting the main wires to be barbed, means for feeding a barb-wire across the main wires and on the same side of both, means for wrapping the ends of said barb-wire about said main wires, respectively, and means for supporting said barb-wire at a point between the main wires during the operation of wrapping, substantially as and for the purpose set forth.

2.
