WIRESTRETCHER.

Application filed November 13, 1919.

T 0 all whom it may concern Be it known that l, CrrAnLns L. STARK, a citizen of the United States, residing at La Junta, in the county of Ctero and State of Colorado, have invented certain new and useful Improvements in \Vire-Stretchers; and I do hereby declare the following to be a full, clear, and exact description ofthe 1nvontion, such as will enable others skilled 1n the art to which it appertains to make and use the same, reference being had to the ac: companying drawings, and to the letters and figures of reference marked thereon, WlllCll form a part of this specification.

This invention relates to new and useful improvements in devices for stretching wire fences, and consists of a simple and efficient device of this nature having a yoke or frame terminating at one end in a hook for engagement with a post, and having the arms of the device turned into eyes forming bearings for a crank operating shaft, and upon which a chain winds and which is adapted to be attached to the wire to be stretched, means being provided for holding the purchase of the wire in a taut relation while being stapled. D

My invention has various other detalls or construction, combination and arrangement of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

My invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon, form a part of this application, and in which:

Fi -ure 1 is a top plallview showmg the application of my invention, and

Fig. 2 is an edge view.

Reference now being had to the details of the drawings by letter:

A designates a forked member having two arms B terminating at their ends in eyes C, in which the shaft D has bearings, said shaft being provided with a suitable handle E. \Vashers F are mounted upon the shaft and held from movement toward each other by means of the cotter pins E. Said arms, at points designated by letters H, are bent so that they will be disposed in planes parallel to each other. The shank portion of the yoke or frame is bent to form a hook K designed to engage over a post or other stationary object whereby the device may be easily held while the wire is being stretched.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Serial No. 337,884.

a A. chain N is fastened to said shaft and car-- riesa dog Oat one end for engagement with a wire, and L is a second chain which is also fastened at one end to said shaft and has a dog I at its other end. A third chain R is fastened at T at the crotch of the yoke or frame, and has a hook S fastened to its end.

In applying the device, the hook is caught over a post or other stationary object and the wire to be stretched connected to the dog 0. By turning the crank handle the shaft will be rotated and the chain end wound thereon, thus drawing the wire taut,

and the purchase may be held by causing the hook S to engage one of the links of the chain L. When the wire is thus held, the operator may be at liberty to staple the wire where desired. To release the device a partial rotary movement is imparted to the shaft in one direction in order to obtain suf ficient slack to permit the hook S to be re leased from the link after which the crank be rotated.

When the device is under stress in stretching the two arms will be held from moving toward each other by the washers held by the cotter pins.

What I claim to be new is:

1.. A wire stretcher comprising a forked frame having arms which terminate in eyes, a crank shaft journaled in said eyes, the end of one of the arms terminating in a shank portion bent to form a yoke for engagement with a post or other stationary object, a stretching chain fastened to the shaft, a chain fastened to said frame and having a hook attached thereto, and means "attached thereto for holding a purchase upon the wire to be stretched.

2. A wire stretcher comprising a forked frame having arms terminating at one of their ends in eyes, and united at their other ends, a crank shaft journaled in the eyes, one of the arms being extended from the point of union to form a shank portion that is bent to form a yoke for engagement with a post or other stationary object, a stretching chain fastened to the shaft, a chain fastened to said frame and having a hook attached thereto, a second chain fastened to the shaft and having a hook for engagement with the chain which is secured to the frame.
