WIRE FENCE.

SPECIFICATION forming part of Letters Patent No. 646,648, dated April 3, 1900.

` Application filed July 17. 1899. Serial No. 724,108. (No model.)

T0 all whomf t may concern:

Be it known that I, NATHANIEL D. POPE, a citizen of the United States, residing at Lake Charles, in the parish of Calcasieu and State of Louisiana, have invented a new and useful Wire Fence, of which the following is a specification.

This invention relates to Wire fences, and has for its object to provide an improved runner-Wire which will effectively hold the pickets in place, so as to prevent longitudinal movement thereof upon the fencing and also to compensate for the contractionV and expan` sion of the latter.

To these ends the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the 2 is a detail perspective View of a portion of one of the runner-wires. I

Corresponding parts in both figures of the drawings are designated by like characters of reference.

Referring to the accompanying drawings, l designates an end post, and 2 the pickets of a fence, which are connected together by several runner-wires formed in accordance with the present invention.

As best indicated in Fig. 2, it will be seen that each runner-wire is formed from a pair of strands which are twisted together into a single cable having a plurality ofspaced loops 3 for the reception of the pickets 2. It ispreferable to employ wooden pickets, although other material may be used. Contiguous to the opposite longitudinal sides of each loop, as indicated at 4, the wire strands are twisted tightly and closely together, so as to provide a substantially-rigid loop. Intermediate of these ti ghtly-twisted portions and as indicated at 5 the strands are not twisted so tightly and the twists are much longer than at the points adjacent to the opposite sides of the loops.

In constructing the fence the pickets 2 are embraced by the respective loops 3, the latter iitting tightly the pickets and the tightlytwisted portions 4 at the opposite sides of the loops fitting snugly against the adjacent sides of the pickets and forming stops to prevent longitudinal movement of the pickets upon the fencing. The loosely-twistedportions 5 intermediate of the loops and the tightlytwisted portions of each runner wire will readily contract and expand, according to the variance of the temperature, so as to automatically take up any slack in the fencing and to prevent breakage of the latter, caused by the strain in the contraction of the Wires. As the loosely-twisted portions of the strands are more sensitiverto heat and cold than are the tightly-twisted portions, the contraction and expansion of the runn er-Wires will be au'- tomatcally taken up without affecting the ti ghtly-twisted portions, whereby a rigid fence structure is always maintained. Also by twisting the strands loosely and employing long twists considerable Wire is saved in each runner-wire, thereby greatly reducing the cost of manufacture.

From the foregoing description it will be apparent that the present invention provides an exceedingly durable and inexpensive fence, which results from the relative combination and arrangement of the spaced loops and the loosely and tightly twisted portions of the strands forming the respective runnerwires.

What I claim is A wire fence adapted to expand and contract with varying degrees at different points of its length and comprising pickets and longitudinal runners which consist of two cylindrical wires having a succession of closed loops encircling the respective pickets, said wires being closely and tightly twisted together at opposite sides of the loops, said wires being loosely twisted together between closely-twisted portions, the wires of each my own I have hereto aliixed mysignature in runner being twisted in the same direction the presence of two witnesses. throughout their length, whereby the eX an- T i ,Y 1 sion and contraction 5f the Wires will be nhen A A1 HAB IEL D POPE 5 up Without affecting the tightly-twisted por- Witnesses:
