FENCE BARB.

SPECIFICATION forming part of Letters Patent No. 301,186, dated July 1, 1884:.

Application filed July 17, 1882. (N model.)

T0 aZZ whom it may concern.

Be it known that I, ANDREW J. UPI-IAM, a citizen of the United States, residing at Sycamore, in the county of De Kalb and State of v Illinois, have invented a certain new and useful Improvementin Barbed Wire, which improvement is fully set forth in the following specification, reference being made to the accompanying drawings, in. which- Figure 1 is a plan view of a section of barbed fence-wire embodying myimprovement. Fig. 2 represents, upon an enlarged scale, a section on the line 00 x of Fig. 1, looking in the direction of the arrow, same figure. Fig. 3 rep I 5 resents, also upon an enlarged scale, a side view of a portion of the part shown in Fig. 1. Fig.4 represents, also upon an enlarged scale, a perspective view of the sheet-metal barb complete, separate, and detached, as it appears when finished, ready to be fed in between the strands composing the main fence strand or cable shown in Figs. 1 and 3, as will be hereinafter more fully described. Fig. represents a slight modification of my said inven- 2 tion, as will be hereinafter more fully described. Fig. 6 represents a crosssection on the line y 7 Fig. 5, looking in the direction of the arrow, same figure; and Fig. 7 represents, upon an enlarged scale, the barb shown 0 in Figs. 5 and 6.

My invention relates to barbed wire having barbs made from sheet metal; and the object of my invention is the production of a sheetmetal barb of such form and construction as 3 5 that it can be quickly fed in by hand between the main strands of wire as they are fed forward and cabled or twisted together, while at the same time the barb will be held secure in place between the cable-strands and preven ted from any lateral or rotary motion.

In the drawings, A A represent two strands composing a fence-wire, twisted together in the usual manner, and carrying at suitable intervals sheet-metal barbs A, each of which 5 barbs is composed of a piece of sheet metal which is cut so as to produce points or barbs proper, B, projecting from opposite sides of a base, C, which base is provided with two pairs of lugs, I), which pairs of lugs are at opposite ends of the base C of the barb, and project in opposite directions and respectively straddle the tWo wires, A A.

The modified form of my invention has two barbs on each side of the base 0 instead of one.

As there are thus four barbs proper, they may be bent, as shown, so as to project in four different directions.

The lugs or cars I) are wide enough apart to permit the strand of fence-wire to slip in between them in an easy manner.

It will be understood that the main fence wires A A are drawn or fed through some proper guiding device which keeps them separated fora short distance from such point of separation, thereby enabling the attendant to 6 5 place the barbs in position between the main strands of wire, preparatory to their being clamped in position as the wires are twisted or cabled together.

It will also be seen that the barbs can be manufactured separately and in large quantities, and then fed in by children, thus ena bling barbed wire such as that shown in the drawings to be manufactured at a comparatively slight cost or expense. By so locating the sets or pairs of lugs that such sets project from both opposite sides and opposite ends of the plane of the body of the barb, the barb will much more certainly resist any tendency to displacement in any direction than where so the lugs are otherwise located on the base or body of the barb.

.The advantage, in a sheetnnetal barb, 0f barbpoints that lie in the plane of the cable over those that lie in planes transverse to the 8 5 cable is that the former are so presented to, animals encountering them as to have a long purchase at their bases whereby to resist dis placement.

I am aware that barbs have sometimes been 90 fastened to fence-cables by means of lugs arranged in pairs on opposite sides, so that each pair of lugs clasps a different strand of the cable; but I am not aware that two pairs of such lugs have ever before been so arranged 5 in a barb as to admit of the latter being made of sheet metal by bending.

I am also'aware that sheet-metal barbs have been provided with lugs which were made to clasp the strands of the fence wire or cable by being bent around the same'to such an extent as would necessitate their being bent during or after their incorporation into the cable; but the lugs of such barbs are necessarily longer than are the herein-described lugs, which are intended to clasp the cable-strands only to such an extent as is compatible with their being fed in-by hand after the lugs have been bent into their final position.

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

The sheet-metal barb A, having points 13 r 5 wires A A, straddled by said lugs, as shown 20 and described.
