SPECIFICATION forming part of Letters Patent No. 334,536, dated January 19, 1886.

Application filed May 11,1885. Serial No. 165,063. (No model.)

To all whom it may concern:

Be it known that I, EDWARD J. MILEs, a citizen of the United States of America, and aresident of Kellogg, in the county of Jasper and State of Iowa, have invented an Improved Fence-WVire Stretcher, of which the following is a specification.

My invention consists in, the combination, with a tubular frame, of a reversible detent, a lever carrying a pawl, a chain or perforated bar, and a wire-clamping device, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in whi'ch- Figure 1 is a side view of the fra1ne,to which the lever and pawl and detent are attached. Fig. 2 is a top view of the same, showing a chain extended through the frame. Fig. 3 shows the complete device attached to a fixed post, as required for practical use. Fig. 4 is a transverse section of the frame, showing the bearing for the sliding chain. Fig. 5 is a perspective view of the device.

Ais the bottom, and B B the sides, of a metal frame cast complete in one piece.

0 is an integral hook extending horizontally from the ends of the two sides B.

Nos. 1 and 2 are openings in the bottom A, adapted to admit the detent and pawl to engage a chain, as shown in Fig. 2.

D is a detent pivoted between the sides B in bearings formed in the inside faces of the sides, and secured by means of lugs bent over the ends of the T-head of the detent, as shown in Fig. 2, or in any suitable way.

F is a lug extending horizontally from the top edge of one of the sides B.

G is a lever of the first order,pivoted to the lug.

H is a pawl pivoted to the end of the short arm of the lever.

J is a chain connected with the hook O, and adapted to be fastened to a post, as shown in Fig. 3.

K represents a flexible chain or perforated flat bar,that is adapted to slide on the bottom A of the frame and under flanges Z Z, that extend inward from the inside faces of the sides B, as shown in Fig. 4.

, detent.

M represents a wireclamping device attached t0 the end of the chain K.

To stretch a wire, as required in making a wire-fence, I attach my complete device to a post, as shown in Fig. 3, attach the end of a wire to-the end of the chain by means of the clamp M, turn the detent, and also the pawl, toward the clamp .and wire, and the long arm of the lever toward the fixed post, and then pull the same arm of the lever toward the The pawl that engages the chain will be thus moved toward the post, and draw the chain and the wire attached thereto in the same direction at each backward motion of the long arm of the lever, and at each forward or reverse motion the pawl will slip backward over the chain to take a new hold, while the detent prevents the chain and wire from moving backward. hen the chain and wire are jointly moved forward, the detent allows the chain to'lift it and disengage it from one link to drop into a succeeding link.

To disengage both the detent and the pawl from the chain, I simply invert the detent, and then place the pawl on top of it. The chain can then be moved in either direction and withdrawn from the frame entirely whenever desired.

I am aware that a frame having a hook on one end, a toothed wheel, and a chain have been combined in a wire-stretcher.

I am also aware that pawls have been pivoted to the opposite sides of a frame and to a lever in such a manner that the pawls would alternately engage a chain as the lever was vibrated, and draw the chain through the frame; but my manner of combining a detent with a frame and a pawl with a lever pivoted to a frame, so that-the detent will be automatically operated to restrict the backward motion of a chain drawn forward by means of the pawl pivoted to the lever, and will also, when inverted, hold the pawl pivoted to the lever inoperative, as required, to draw the chain backward through the frame, is novel and greatly advantageous. 7 I claim as my invention-' 1. In a fence-wire stretcher, the combination of a hook-shaped detent, D, having a cross-head at its rear end that terminates in journals, and a lever, G, carrying a hook, H,

with a frame having hearings for a sliding chain, for the purposes stated. 5 2. A wire-stretcher composed of a frame, ElnvARD MILES A B B, having an integral hook, G, alever, G, \Vitnesses:

pivoted to the frame, a pawl, H, pivoted to G. J. PRATT,

said lever, a detent, D, pivoted to said frame, T. G. S. COOPER.

and a chain or perforated bar having a Wireholding device at its end, to operate in the IQ manner set forth.
