My invention is primarily designed to be used in tightening the wires of wire fences, but is not limited to this use only; and it relates to that class of tighteners which can be reversed and used in drawing the wire either from the right or left. The invention consists in providing the stretcher with a single weighted bar, so constructed and combined with the instrument that such bar serves the purpose of a pawl when the tightener is in the positions shown in Figs. 1 and 2, the bar or pawl being self adjusting when the device is reversed, as hereinafter fully described. In the drawings, A represents a windlass > .supported in a suitable frame, B. C is the crank. D is a ratchet-wheel connected with the windlass on the outside of the frame. B is a piece of metal, which serves the purpose of a pawl, the point a of which engages with the ratchet D. & is a slot in B; c is a pin or pivot projecting from the side of the frame into the slot &. d is a hook or a rest and guard for the rear end, e, of the part E. This hook a also projects from the side of the frame. The bar E may be called a "double pawl." When the stretcher is in the position shown in Fig. 1 this pawl E is, in effect, pivoted upon the hook d, and the slot l permits the forward end or point, a, to rise and fall as the windlass and ratchet thereon are rotated. At the same time the point a will be held in contact with the ratchet by the weight of the pawl, as is customary.
