WIRE-SPLICE.

SPECIFICATION forming part of Letters Patent No. 598,275, dated February 1, 1898.

Application filed October 2 9, 1 8 9 7.

To alt whom it may concern:

Be it known that I, ORVILL H. SAWDY, a citizen of the United States, residing at Adrian, in the county of Lenawee and State of Michigan, have invented a new and useful Improvement in Wire-splices, of which the following is a specification.

The object of my invention is to provide a construction of splice for wire which shall be of advantage for use more especially in wire fence by resisting tendency to unwind under strain and which shall be such as to cause the friction under strain of one end to be in the direction opposite that of the other end, and thus render it impossible for either to unwind, besides relieving the portions weakened by bending of a great portion of the strain.

My invention relates particularly to an improvement on the so-called telegraphsplice, in which the end portions of two wire lengths are interlocked by bending each at some distance short of its extremity upon the other and twisting or coiling each beyond the bend about the other. Thus a bend is made in each wire which is injurious, because the wire is thereby weakened, and when the splice is put under strain its tendency is to unwind, and it will unwind at a much less strain than the tensile strength of the wire will resist, provided the wire does not break at either bend in the splice.

Referring to the accompanying drawings, Figure l is a View in the nature of a diagram showing the initial bends in the two wire ends produced in forming my improved splice, and

Fig. 2 is a view showing the completed splice.

A and B are two wire lengths having their end portions brought together to overlap each other. At a desired distance from the extremity of each end portion the latter is bent about the other adjacent end portion, as shown at a and b, and the remainders a and Serial No. 656,786, (No model.)

b of the end portions of the two wires are both coiled backward or toward each other about the two overlapping sections of the end portions to a point preferably about midway of the overlapping sections, as shown at a and b in Fig. 2. Thus the end portions of the two wires are brought toward each other near the center of the splice, thereby materially reinforcing that portion of the wire that has been weakened by bending.

WVhen this splice is subjected to heavy strain, the wire A gradually tightens where it first passes about the wire B at a and produces great friction, thereby relieving the wire 13 of a great portion of the strain where it is weakened by the bend at b. The same is also true as to the wire 13 where it first passes around the wire A at a. The construction of this splice is such that the friction of one end is against and in the opposite direction to that of the other end, rendering it impossible for either to unwind, like the telegraph-splicehereinbefore referred to.

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

1. In a wire-splice, the wires A and B having sections'of their end portions overlapping each other and the remainders of said end portions coiled toward each other about said overlapping sections, substantially as and for the purpose set forth.

2. A wire-splice comprising the wires A and B having sections of their end portions overlapping eachother, said end portions being bent at a and b and thence coiled toward each other about said overlapping sections to ter minate about midway of the length of said overlapping sections, substantially as and for the purpose set forth.
