IMPROVEMENT IN WIRE-FENCES.

Specification forming part of Letters Patent No. 157,124, dated N uvember 24, 1874; application filed October 27, 1873.

To all whom it may concern:

Be it known that I, JOSEPH F. GLIDDEN, of De Kalb, in the county of De Kalb and State of Illinois, have invented a new and valuable Improvement in fire-Fences; and that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in which- Figure 1 represents a side view of a section ot fence exhibiting my invention. Fig. 2 is a sectional view, and Fig. 3 is a perspective view, of the same.

This invention has relation to means for preventing cattle from breaking through wirefences 5 and it consists in combining, with the twisted fence-wires, a short transverse wire, coiled or bent at its central portion about one of the wire strands of the twist, with its free ends projecting in opposite directions, the other wire strand serving to bind the spur-wire firmly to its place, and in position, with its spur ends perpendicular to the direction of the fence-wire, lateral movement, as well as vibration, being prevented. It also consists in the construction and novel arrangement, in connection with such a twisted fence-wire, and its spur-wires, connected and arranged as above described, of a twistingkey or head-piece passing through the fencepost, carrying the ends of the fence-wires,

and serving, when the spurs become loose, to

tighten the twist of the wires, and thus render them rigid and iirm in position.

In the accompanying drawings, the letter B designates the fenceposts, the twisted fence-wire connecting the same being indicated by the letter A. O represents the twisting-key, the shank of which passes through the fence-post, andis provided at itsend with an eye, b, to which the fence -Awire is attached. The outer end of said keyr is provided with a transverse thumb piece, c, which serves for its manipulation, and at the same time, abutting against the post, forms a shoulder or stop, which prevents the contraction of the Wire from drawing the key through its perforation in said post.

The fence-wire is composed at least of two strands, a and z, which are designed to be twisted together after the spur-wires have been arranged in place.

vent them from vibrating laterally or being pushed down by cattle Vagainst the fencewire. Although these spur-wires may be turned at once around the wire strand, it is v preferred to form the central bend first, and to then slip them on the wire strand, arranging them at suitable distances apart. The spurs having thus been arranged on one of the wire strands are xed in position and place by approaching the other wire strands z on the side of the bend from which the spurs extend, and then twisting the two strands a z together by means of the wire key above mentioned or otherwise. This operation locks each spur wire at its allotted place, and prevents it from moving therefrom in either direction. It clamps the bend of the spur-wire upon the wire a, thereby lholding it against rotary vibration. Finally,

the spur ends extending out between the strands on each side, and where the wires are more closely approximated in the twist, form shoulders or stops, s, which effect-ually prevent such rotation in either direction.

Should the spurs, from the untwisting of the strands, become loose and easily movable `on their bearings, a few turns ot' the twisting-key will make them firm, besides straighteniug up the fence-wire.

Wha-t I claim as my invention, and desire to secure by Letters Patent, is-

A twisted fence-wire having the transverse spur-wire D bent at its middle portion about one of the wire strands a of' said fence-wire, and clamped in position and place by the other wire strand z, twisted upon its fellow, substantially as specified.
