MILLAR MATHESON, OF CHARLOTTETOWN, CANADA.

WIRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 721,716, dated March 3, 1903.

Application iled April 25, 1 902. Serial.1\lo.104, 579. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, MILLAR MATHEsoN, a subject of theKing of Great Britain, residing at Charlottetown, in the county of Queens, Province of Prince Edward Island, Canada, have invented certain new and useful Improvements in Wire-Stretchers, of which the following is a specification.

My invention relates to improvements in wire-stretching devices; and the object of the invention is to provide awire-stretcher whereby the user can stretch a fence-Wire in either direction while working on one side of the fence and which shall be simple and economical to manufacture; and it consists, essentially, of a lever-handle provided with a V-shaped end and a clamp pivotally attached adjacent to an upwardlyprojecting flange on the said V-shaped end, the various parts being constructed in detail as hereinafter more partic ularly described.

Figure l is a general perspective view of my device. Fig. 2 is a detail of the clamp. Fig. 3 is a detail of the lever.

Like letters of reference indicate corresponding parts in each figure. i Y

a is the lever, provided with 'an ordinary handle, and b is the V-shaped end thereof,

which is preferably a casting securely attached to the lever. The end b converges from the shoulder c to the point d, having the fiat edges e and f. The ange e projects upwardly from the surface of the end b and eX- tends in a curved direction from shoulder to shoulder.

h is a clamp terminating in the lips t andy and designed to be pivotally attached to the upper side of the lever d by the pin 7c, ad jacent to the upright flange g.

In order to put my devicek to practical use, I rest the edge f against the side of the fencepost, and the Stringer of the projected fence is brought partially around the post and inserted between the langeg andthe lip t' and tightened therein by `means of the bar h. The lever a is then pulled, so as to tighten the wire, the end b forming a purchase against lthe post. VAt suitable staple or fastening is then used to attach the wire firmly to the post. The samejoperation vexactly occurs when it is desired topull the wire in the other direction, with the exceptionV that the edge e rests against the post on the other side of the latter and the lip 7' is used to hold the wire to the flange g.

It will be seen from the foregoing description that the Stringer-wires on a fence can be tightened from either direction, obvating the necessity of crossing to the other side of the fence. The simplicity of this device must be also mentioned here, as it consists of only three parts, all cheap and readily manufactu red.

What I claim as my invention is A wire-stretehing device, comprising a lever having a substantial V-shaped end, each side of said end being concavely depressed between the shoulder and the tip, an arcshaped projecting 'flange extending from shoulder to shoulder of the V-shaped end, a

Yclamp having a pair of lips,and an arm rig- :idly attached to the pair of lips, and pivotally arranged on the lever in proximity to the arc-shaped projecting flange, as and for the purpose specified.

Signed at Charlottetown this 10th day of April, 1902.
