WIRE-FENCE STRETCHER.

SPECIFICATION forming part of Letters Patent No. 736,32 3, dated August 11, 1903.

Application filed March 28, 1902.

To all whom it may concern.-

Be it known that I, ISAAC M. WVARNER, a citizen of the United States, residing at Union City, in the county of Branch and State'of Michigan, have invented a new and useful Wire-Fence Stretcher, of which the following My invention is an improved wire-fence stretcher; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed.

The object of my present invention is to effeet improvements in the construction of the in operative position.

stretcher-bar.

In the accompanying drawings, Figure 1 is a side elevation of a wire-fence stretcher embodying my improvements, showing the same Fig. 2 is a detail sectional view showinga portion of the stretcherbar and the stretch er-wheel mounted therein. Fig. 3 is a front elevation of the same. Figs. 4 and 5 are detail elevations showing a modification.

My improved stretcher-bar comprises the two sections 1, which are flattened bars of iron, steel, or other suitable .material, provided at suitable points, here shown as near their upper and lower ends, with lateral outstanding offsets 2, which form openings 3 sufficient in size to receive the stretcherwheel 4 and to clear the stretcher-chains 5. The said sections 1 are secured together by bolts 6, and it will be understood that in operation the sections of the stretcher-bar are clamped on opposite sides 'of the runner- Wires a of the fence or of a fence fabric. The vertical portions 2 of the lateral outstanding offsets of the stretcher-bar sections are'provided with inclined slots 7, which form the bearings for the shaft or axle 8, which carries the stretcher-wheel 4, so that the latter may be detachably mounted in said lateral outstanding offsets and successively employed at (liiferent portions of the stretcher bar in stretching the upper or lower running wires or the upper and lower portions of a wirefence fabric. The stretcher-wheel is provided with radial sprockets 9, which are adapted to engage the openings in the links of the stretcher-chains. In each of the openings 3, in one side thereof, is a pawl 10, which $erialN4l.100A (No model.)

One end of the shaft or axle 8 projects a sufficient distance beyond the stretcher-bar to form the pivot for the operating-lever 13. The same is provided with a pawl 14, which is also adapted to engage the ratchet-wheel It will be understood that When'the lever 13 is oscillated the pawls 10 14 coact with the ratchet-Wheel 12 to rotate the stretcher-wheel by a step-by-step movement, and hence the I stretcher-whee1 being in engagement with one of the stretcher-chains stretches the fence to the requisite extent.

In the opposing sides of the stretcher-bar sections 1 at appropriate points, here shown as above the offsets 2, are openings 15, which extend from the fron t side of the stretcher-bar to the rear side thereof, and in the said openings are disposed the shanks of eyebolts 16. Holder hooks 17 of suitable construction, adapted to grapple and hold the stretcherchains under tension, are connected to the eyes of the bolts 16 by chains 18.

In Figs. 4 and 5 I show a modification, in which there is a clutch member 12 on the outer side of the ratchet-wheel 12, and the lever 13, whichis fulcrumed on the shaft 8, has 011 its inner side a clutch member 13. The lever is movable laterally on the shaft 8, so that the clutch member 13 may be engaged with and disengaged from the clutch member 12 at will. It will be understood that by appropriately operating the lever the ratchetwheel, and hence the chain -wheel 'on the shaft, may be rotated by a step-by-step movement, the pawl 10 by engagement with the ratchet-wheel, as before described, preventing reverse rotation of the ratchet-and chain wheels.

No claim is made therein to the hook connected to the stretcher-bar and adapted to engage the ch ain tolock the stretcher-bar thereto when the chain is under tension and relieve the drawing means of the stress exerted thereon by the chain, as the same isclaimed in my copending application for Letters Patent of the United States, Serial No. 95,986.
