WIRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No'. 363,805l dated MayASl, 1887.

Application filed December 29, 1886. Serial No.

' first fully described, and then pointed out in the claim.

In the drawings, Figure 1 is a perspective View of an improved wire fence, showing the winding, tying, bracing, and keeping attachments. Fig. 2 is a front elevation of thewinding mechanism. Fig. 3 is a transverse section of same, cut through line a: x of Fig. 2. Fig.

4 is a front elevation ot' the post-bracing mechanism. Fig. 5 is a side elevation of same. Fig. 6 is a perspective View of the fencewire keeper, and Fig. 7 is a similar view ofthe bifurcated or inverted V-shaped fence-wire tie.

Upon the outer face of the end fence-post, A, are securely attached winding mechanisms, head-blocks, or windlasses B, a windlass being provided for each strand of the fence-wire C. Constructed in the periphery of the drum a of the windlass are ratchets b. Operating upon these ratchets is a pawl or stop, c. This pawl (constructed with a feather or tail-piece, 61,'

which loosely rides in a recess formed by the drum-bearings b and b2 at the sides, and by the ratchet portion of the drum and back plate, e, at the ends) is provided with a lifting-finger,

. f, projecting outside of the windlass-frame and riding looselyin slot g, cutinto the upper edge of bearing b. This pawl is kept in contact with the drum-ratchets by its o'wn weight, and automatically rises out of one ratchet-recess and drops into the next as the drum or windlass is turned by means of a wrench applied to square ends h of the drum. In the usual form of wire-fence windlasses the rusting of the pawlpivot, incidental to exposure to the weather, precluded the free working of the pawl on its pivot, and thus great difficulty has been experienced in tightening the fence-wires. In

my improvedl windlass this difficulty is entirely obviated.

A series of bifurcated wire ties, D, of an inverted-V shape, are securelylashed or tied to each crossing strand of fence-wire, the hook or loop i, constructed on the upper or angle end,'engaging with one of the upper strands, preferably the one next to the top, while the hooks or loops j 0n the two lower extremities of the brace engage with thelowerniost strand. These ties are located at stated and constant intervals with reference to each other, the distance between the sides of two contiguous braces being equal to the distance between theA two lower ends of each tie, as shown in Fig. l.'

This novel method-of locating and attaching the braces evenly distributes the bearing strain on the several strands of fence-wire, and while adding strength to the fence also admits of the intervening posts being located farther from each other than has heretofore been the custom.

Upon intervening posts, A', are screwed or otherwise fastened keepers E. These keepers are each provided with a slot or passage-way, lc, and enlarged orifice Z. By means of this peculiarly-shaped keeper the wire, while held away from frictional'contact with thepost and supported in its proper location, is left to freely slip forward as it is being tightened by the windlass, the slot forming a passage-way for the already-stretched wire to pass into the enlarged orifice prior to fastening the keeper to the post.

Post-braces m m are let in at their upper ends' tothe end or head-block post, A, and are located with reference to each other in such a manner as to leave a passage-way for the strands of fence-wire to pass between them, as shown in Figs. l and 4. The lower ends of these brace-posts are seated in metal shoes n n, which are so constructed as to also Vform caps for small supplemental posts 0 o. Slots p p are also cut into the lower ends of the postbraces, by which connectingor brace rodsfq q are saddled77 Thebra'cefrods pass' through the post-braces can be put in place and removed Without having to Withdrawr the rod.

I am aware that head-blocks or windlasses provided with drums having ratchets and pivoted pawls constructed thereupon have heretofore been used; that single upright Wire braces or ties have heretofore been Wrapped to crossing strands of fence-wires; that staples or other equivalent devices have been adopted to hold the several strands of wire fence in their proper places, and that post-braces {ittng in metallic shoes located on supplemental posts (the several parts being tied together by abrace-rod) have been used, and are therefore not broadly claimed herein; but

' What I do claim, and desire to secure by Letters Patent, is

In a wire fence, the combination7 ith the Y i post, of a head-block secured thereto and hav- Y DAVID CLEAVER.
