BARBED WIRE Filed March 17, 1959 RZ/dO/f' Brixne r" BARBED WIRE Rudolf Josef Georg Brixner, Herrenhaus, Witzhave, Stormarn, Germany Filed Mar. 17, 1959, Ser. No. 800,042 Claims priority, application Germany July 26, 1953 '4 Claims. (Cl. 256-6) This invention relates to a barbed wire which is formed by two separate wires with spiked tufts.

Barbed wire has already been used in which the spiked tufts are arranged on one wire. However, in wire of this type the spiked tufts are frequently not fixed sufficiently firmly and can slide on the Wire. Consequently it has been proposed to make the wire undulated to afford a better hold for the spiked tufts. As this construction also does not ensure sufficiently that the spiked tufts do not shift, it is also known to treat the surface of the wire to aiford additional hold for the spiked tufts by forming kinks or dents in the wire or otherwise working the surface thereof. The working of the surface of the holding wire for the spiked tufts results in weaknesses in the wire so that there is a danger of the wire breaking.

It is also known to twist tWo wires together and to arrange the spiked tufts on one wire so that they are secured against shifting by the twist. In this form of construction the wire which is not used for carrying the spiked tufts can be pressed away. Moreover, in the case of a twisted wire places where moisture can collect are formed and as a result corrosion of the wire soon sets in even if the wire has been subjected to a surface protecting treatment.

It is the object of the invention to avoid the known objections to barbed wire.

The main feature of the invention consists in that two separate wires are arranged side by side and at a distance apart and the position of said wires in relation to each other is fixed by means of spiked tufts. One end or some of the ends of the spiked tuft wraps or wrap the two wires with its or their loops and the other end or ends of the spiked tuft is or are twisted together between the wires. The wire loops wrapping round the outer side of the two wires prevent the spacing between the wires from becoming greater and the twist between the wires prevent the spacing between the wires from becoming smaller. The spiked tufts cannot therefore shift on the wires and, at the same time, cannot be turned on the wires. Moreover, there are practically no places where moisture can collect because the wires are not in contact with each other and can easily dry in the air.

Another feature of the invention consists in that the two separate Wires are waved or corrugated, thereby increasing the strength of the barbed wire. Consequently deformation of the wires carrying the spiked tufts is positively avoided.

Two preferred embodiments of the invention are illustrated by way of example in the accompanying drawing, in which:

Fig. 1 shows an embodiment with two separate straight wires carrying spiked tufts, and

States Patent 2,973,185 iatented Feb. 28, 1961 strength. These wires are arranged side by side at a distance apart and carry spiked tufts 3 at predetermined distances apart. These spiked tufts 3 may be composed of one, two or four wire sections pointed at each of their ends. In the embodiments shown in Figs. 1 and 2, there are shown two wire sections pointed at their ends 4, 7 and 5, 8, respectively. The ends 4 and 5 of the Wire sections surround the wires 1 and 2 with loops 6 and prevent the distance between the wires 1 and 2 from becoming greater. The other ends 7 and 8 of the wire sections are Wound between the wires 1 and 2 and twisted together at 9 and prevent the space between the wires 1 and 2 from narrowing. By this manner of fixing the spiked tufts 3 on the two wires 1 and 2 arranged at a distance apart, a turning or shifting of the spiked tufts is impossible. The wires 1 and 2 cannot form any places where moisture can collect because they are arranged free from each other so that the barbed wire according to the invention has a long life.

Fig. 2 shows two separate wires 10 and 11 which are waved or corrugated whereby the strength of the barbed wire is increased.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

I claim:

1. A barbed wire construction comprising a pair of substantially parallel support wires, a barb on said support wires comprising a pair of Wires, a first end of one of said wires extending around said pair of support wires and having a reversely bent portion between said support wires and a second end extending in the same direction as its first end, the second of said pair of wires having a first end on the opposite side of said support wires from the first end of said first wire, said second wire extending around said support wires and having a reversely bent portion engaged in the reversely bent portion of said first wire and having a second end extending in the same direction as its first end.

2. A barbed wire construction as in claim 1, wherein the first and second ends of the first wire of said pair of wires extend at opposite sides of the support wire adja' cent said ends.

3. A barbed wire construction as in claim 1, wherein the first and second ends of the second wire of said pair of Wires extend at opposite sides of the support wire adjacent said ends.

4. -A barbed wire construction as in claim 1, wherein the first and second ends of each of the first and second wires of said pair of wires extend at opposite sides of the support wires adjacent said ends.
