BARBED WIRE.

fiPECIPICATION forming part of Letters Patent No. 336,664, dated February 23, 1886,

Applibation filed April 26, 1884. Serial No. 129,342. (No model.)

To all whom it may concern:

Be it'known that 1, JAMES POTTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Barbed Wire, of which the following is a specification.

My invention relates to improvements in barb-wire in which the barbs are formed separate from the cable andinserted therein. The barbs and cable are united, as hereinafter described, so asto produce a strong, flexible, and durable fence-wire.

The object of my invention is to form a fence wire in which the eyes of the barbs shall act as a protection to prevent cattle or stock from tearing their skin when they come in contact with the barb, and still in its construction to leave enough of the prong of the barb to serve the purpose of a fencing-wire. I attain this object by the construction illus trated in the accompanying drawings, in which Figure 1 is a plan of my invention as complete. Fig. 2 is a similar view the reverse of Fig. 1. Fig. 3 is a plan with one of the ca ble-strands broken away to show how the barbs are held within the twist of the cable. Fig. 4 is a plan of the barbs as they appear before inserting them in the cable.

Similar letters refer to similar parts.

a and I) represent two strands of wire of any desired size andmaterial, which are twisted into a single cable, as illustrated in the several views of the drawings.

At any suitable distance apart the barbs are secured to the cable in the following manner: In making the barbs I employ a single piece of wire, 0, having prongs orpointed ends 0 0. At or about a quarter the length of said wire I bend the wire to form the loop or eye a. I then carry the wire diagonally across to the opposite side and form a similar eye, 0. I then carry the end of the wire still farther, until the prong 0 extends beyond the eye. 0.

The barbs,when thus formed, resemblea letter S with the ends of the letter extended. I then draw the two ends 0 and 0 together until they lie side by side and parallel with each other, the ends 0 0 extending beyond the eyes a c to form the prongs of the barb.

In securing the barbs to the cable, as shown in Figs. 1 and 2, at certain intervals, the strands a b are separated. The strandbatthe place of separation is wrapped once around the barb centrally, forming the loop (I, and is again united with the strand a at the point d. The strand a at the place of separation passes diagonally across the middle of the barb parallel with the loop (I. The barbs are thus placed with a double strand of wire on each side, one portion of the strand 2) passing within the twist of the cable, thus securing the barbs from lateral or horizontal displacement.

What I claim as new, and desire to secure by Letters Patent, is

l. The combination, with a fence-wire, of a barb having broad eyes and prods or points arranged lengthwise of the barb and in contiguity with the rounded ends of the eyes, which cover all but the extremities thereof, substantially as described.

2. The combination, with a barb having broad eyes and longitudinal points arranged in contiguity with the rounded ends of said eyes,w'hich cover allbut the extremities thereof, of the fence-wire wrapped around the narrow neck of the barb between said eyes, substantially as described.

3. A barb for fence-wires consisting of a single piece of metal bent into figure-of-eight form, having two broad eyes, a narrow neck between the eyes, and two points laid against the eyes and protected thereby, substantially as described.
