While the particular construction of my improved stretcher is the best known to me for its purpose, it may be variously modified, as to details, without departure from my invention. For example, I do not desire to limit my improvement to the use ot the sprocketwheel B3, since any suitable form of pulley, for winding upon it aexible connection with Wire to be stretched, may be used. Furthermore, I may employ only one dog and one ratchet; or it' two of each be employed, they need not, necessarily, he on opposite sides of the sprocket-wheel.

For the sake of brevity I refer to my invention in the foregoing description and in the appended claims, as a stretcher and wirefence4 stretcher. I use it, however, for other pulling purposes, as well as for stretching. Hence I do not wish to be understood as limiting my invention to its mere stretching function, but intend to cover it for any pulling purpose to which it is applicable.

`What I claim as new, and desire to secure by Letters Patent, is-

l. In a wire-fence stretcher, the combination with a frame of a cog-wheel journaled therein, means connected with said wheel to rotate with it for engaging a flexible connecting medium between the stretcher and fence to be stretched, an eccentric journaled in the frame, and carrying a dog to engage said cogwheel, and means for working the eccentric, substantially as described.

2. In a wire-fence stretcher, the combination with a frame of a cog-wheel journaledV therein, a sprocket-wheel connected with the tion with a frame of a pair of cog-wheels I journaled therein and carrying between them a sprocket-wheel, a stripper ou the frame in advance of said sprocket-wheel, an eccentricshaft journaled in the frame, a pair of dogs having its members on dierent ecceutrics of said shaft, each to engage one of said cogwheels and be actuated alternately back and forth with relation thereto by Working said shaft, and an operating handle on the crankshaft, substantially as described. h

4. A wire-fence stretcher comprising, in combination, a rectangular frame A carrying at one end a clevis p, a combined double cogwheel and interposed sprocket-wheel device B journaled in the frame near one end thereof,

a stripper C on the frame adjacent to said sprocket-wheel, an eccentric-shaft E journaled in the frame near its opposite end, dogs D and D respectively on the eccentrics lr and r ofjsaid shaft and au operating handle F on the shaft, substantially as described.
