TIO ALL WHOM IT MAY CONOERN:

Beit known that I, F. H. CRANDALL, of Ontario, in the county of Wayne, and State of New York, have invented a certain new and useful Improvement ia Devices for straining Wire Fence; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specitication. I

Figure lis a front elevation of my improved fence.

Figure 2 a perspective view of a. modification of the same.

Figure 3 a perspective view of one of the straining-devices detached.

Like letters of reference indicate corresponding parts in all the figures.

My invention consists in a device for straining wire fence, consisting of a bolt having a lscrew-thread cut upon one end for screwing into the post, and eyes formed in the body for the connection ot' the ends of the wire, and a socket, 0r a square head, or some equivalent arrangement, for fitting the instrument that turns the bolt, all as hereinafter described.

As represented in the drawings, A A are posts' connected by suitable braces or stiii'eners a a, and B B are the panels or sections oi fence connected with the posts.- Fig. 1 represents a fence that is made by weaving the pickets Z7 b in strands of wire c e, that are crossed alternately to bind the pickets. Fig. 2 represents vsimply wire lengths, which form the panels or sections, without pickets7 being stretched lengthwise. My improved device is capable t" attaching to either form. The wires are rigidly attached at one end, as shown at d. The opposite ends are passed through eyes ff of bolts O C. Each bolt is made straight, of suitable length, and has a screw-thread, g, out upon its end, which screws into the post. It also has a socket, 7L, for the insertion of a lever to turn the bolt, or the end is made square, as showuat the top in fig.1,for the application of a wrench, or some equivalent arrangement is employedk whereby the bolt may be easily turned.

The operation will be readily understood. The threaded portion of the bolts is screwed into the side of the post, leaving the ends projecting, with the wires fastened in the eyes. `Wl1enever it is desired to strain or tighten the wires, the bolts are turned inward, and when it is desired to unstrain or loosen them, the bolts are turned in the reverse direction. By this means, I am enabled to compensate for contraction and expansion, caused by the difference in the temperature in winter and summer, which obviates one of the greatest difficulties in the wireA fence. It will be seen that the adhesion of the threaded part of the bolt to the fibres of the wood is suicient to prevent its turning under the ordinary tension of the wires, and thus they are kept taut, but when great contraction is produced by severe cold, the force acts to unscrew the bolt suiciently to prevent the breaking of the wires. Thus, by means of the screw-thread, a connection is formed with the side of the post, that can be relied onto maintain proper tension, and yet be self-adjusting under great variations of temperature, and this device secures the great advantage of having the connection entirely outside of the post, where theI wire can be applied with greater rapidity, and much less cost, than when entering or passing through holes in the posts for the same purpose. 'lhey also take up the slack from sagging or the stretching of the wires. This e'ect is of much value, especially in connection with the woven pickets, as in fig. 1, for it enables the pickets to be tightened up when they become loose. t

By the employment of the bolts C, I am enabled to'connect with any ordinary post, which is far better than would be if the post had to be especially formed for the attachment'ot` the straining-device, and this device itself of la complicated nature.' My bolts are of the simplest, cheapest, and most effective form, and have siin ply to be screwed into the post.

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

The threaded bolt C, constructed, arranged, and applied substantially in the manner and for the purposes herein set" forth.

. In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
