IMPROVEMENT IN FENCE-WIRE STRETCHERS.

Specification forming part of Letters Patent No. 222,01 3, dated November 25, 1879; application filed August 7, 1879.

- in Fence-Wire Stretchers; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The nature of our invention consists in the construction and arrangement of a machine for stretching wire, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawings, in which-- Figure l is a plan view, Fig. 2 a longitudinal section, and Fig. 3 a detail view, of our invention.

A represents the frame of our wire-stretching machine, which frame forms ahead at one end. On this head is a hollow box, B, serrated on its inner surface, and a cam-lever, O, similarly serrated, is pivoted on the head, and works against the serrated surface of the box to hold the wire perfectly tight.

In the frame A is a slide, D, on which is a box, B, and cam-lever 0, similar to those described on the head of the frame. The side edges of the slide D have V-shaped grooves fitting over similar flanges in the frame, as shown at a a. The slide D is, by a cord, 1), connected with a drum, E, placed loosely on a shaft, (1, and connected to said shaft by a pawl, e, and ratchet f. On one end of the shaft cl, within a slot or mortise in the frame, is secured a cog-wheel, F, which meshes with a Witnesses:

pinion, G, mounted on a short stud or shaft having a crank, H, on its outer end for rotat ing the same.

h is a pawl to take into the cog-wheel E to prevent any backward motion thereof;

The head of the frame A has a forked pro jection, I, with a screw, t, passing through the same for attaching the device to a fence-post or other stationary object for use. When thus attached the wire is placed in the box B and held by the cam-lever 0. By now turning the crank H the drum E will be rotated, the pawl e being in engagement with the ratchet-wheel f, and the cord b will draw the slide D forward, stretching and straightening the wire. The wire is then clasped by the cam-lever O in the box B, and the lever C loosened, so that by disengaging the pawl e the slide can be moved back for the purpose of taking a new hold, if desired.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

In a fence-wire tightener, the frame A, having the forked projection I, screw i hollow serrated box B, guides a, and cam-lever G, in combination with the grooved slide D, having a reciprocating movement in said frame, and provided with the hollow serrated box B and cam-lever O, cord 1), drum E, pawl and ratchet cf, gears F G, pawl h, and crank H, the whole constructed and arranged to operate in the manner and for the purpose set forth.

, In testimony that we claim the foregoing as our own invention we affix our signatures in presence of two witnesses.

THOMAS E. CLARK. W. W. ORRIS.
