BARBED-WIRE FENCE.-

SPECIFICATION forming part of Letters Patent No. 238,255, dated March 1, 1881.

Application filed October 6, 1880.

To all whom it may concern Be it known that I, THOMAS SHUMAN, of Corning, in the county of Adams and State of Iowa, have invented certain new and use ful Improvements in Barb-Wire Fences; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the IO same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to an improvement in wire barb fences; and the invention consists in certain features in construction and combinations of parts, as will hereinafter be described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view, in perspective, of a section of fence built in accordance with my invention. Fig. 2 is a detached view of the jointed wire. Fig. "3 is a plan view of one of the stay-blanks. Fig.

4 shows the blank after having its ends slotted.

v Fig. 5 is a plan view, and Fig. 6 an edge view,

of the stay after it has been bent into the desired form.

A represents thewires of a fence. Instead of being composed of continuous strands of wire, as in ordinary frames, each wire is composed of the links B, which may be of any de sired length, size, and shape. The opposite ends of each link are cut diagonally, and the ends then bent over toward each other to form 5 loops a b on opposite ends of the link, the

ends being bent outwardly or at right angles to the length of the link, forming barbs o c. When the several links are secured together, which operation is readily accomplished by 4o inserting the loop at one end of the link of the loop of the next adjacent link, a barbwire is formed having sharp barbs projecting in opposite directions. This form of construction is very valuable in many places when it i 4 5 is sometimes desired to move the fence or take (No model.)

put up in packages and readily transported, o

as illustrated in Fig. 4, and one portion of the divided or slitted end is bent over onto the stay and then outward, thereby forming aloop,

d, and outwardly-projecting barb c. The other portion of the divided ends of the stay constitute end barbs, f f. The stays G are attached to the wires, as shown in Fig. 1, and serve a twofold purpose. They operate to strengthen the panels of the fence by binding the wires together, and prevent the wires from sagging, thereby permitting sufficient slack wire to obviate any danger of breaking the wire by its contraction in cold weather and still maintain proper space between the seve- 7o ral wires. The stays also serve to furnish the required barbs for the fence. The end barbs of the stays, in connection with the laterallyprojecting barbs, furnish ample protection to the fence.

The loop may be readily attached to the wires, as the outwardlybent barbs form a throat at the entrance of the loop into which the wire is guided and is forced into the loop, it being retained therein against accidental displace- 8o ment by the springing qualities of the metal of which the stay is manufactured.

From the foregoing it will be observed that myimproved stay admits of the exercise of the greatest economy in its manufacture.

By cutting the stays with diagonal ends and then slitting the ends, as described, two sharp-pointed barbs are formed without waste of metal. These stays may be attached to any construction of wire fence, either barbed 0 or plain. The edges of the stays may be left smooth,or they may have barbs formed thereon by a cut, the severed portion being bent outwardly from the main body of the stay.

It is evident that slight changes in the con- 5 struction and relative arrangement of the parts might be resorted to without departing from the spirit of my invention, and hence I would have it understood that I do not limit the otherhalf bentback upon the stay, forming myself tothe precise construction and arrangea loop, the end of the latter being bent outment of parts shown and described but Wardly to form a lateral barb, substantially as Having fully described my invention, What set forth.
