DEVICE FOR STRETCHINGWIRE.

SPECIFICATION forming part 0f Letters Patent N0. 679,856, dated August 6, 1901.

Application led September 10,1900. Serial No. 29,561. (No model.)

To a/ZZ whom it may concer-n,.-

Beit known that I, WILLIAM McCLosKEY, a

citizen of Canada, residing at Essex, in the county of Essex and Province of Ontario,

Canada, have inventedcertain new and use-A nation of parts hereinafter described, andY shown in the accompanying drawings, in which- Figure l is a plan of myimproved device` shown as in operation as a wire-stretcher. Fig. 2 is a side elevation thereof. Fig. 3 is a sectional plan view illustrating the device as in use for coiling Wire. Fig. 4 is a detached section of the ceiling-tube.

A is a rigid frame formed with two parallel side bars, in which is journaled, transversely thereof, a shaft B, projecting at one end for the attachment of a crank-arm C, having a handle c. Upon the shaft B are secured,with

in the frame, the sprocket or 'chain pulley D` interchangeably secured to eitherthe shaft B or G.

H is a chain adapted to engage with the chain-pulley D and provided at both ends ywith suitable wire-grips I.

.I is a rigid curved arm or hook secured to the rear end of the frame or formed integrally with it and terminating in a tooth K.

L is a fork at the front end of the frame, preferably integrally formed with one of the side bars thereof and adapted to engage and hold one end of the chain.

To the crank-arm is pivotally secured at a a lever b, to the outer end or short arm of which the handle c of the crank is detachabl y seby the arm J, all as shown in Fig. l.

cured, while the inner end ofthe long arm is connected by a tension-spring cl to the crankarm, all so arranged that in applying the `power to the crank-handle it will cause the lever b to assume4 more or less of an angle to the crank-arm, and by means of a scale e in the median line of the arm the arm b serves `as an indicator of the degree of power applied 6o to the crank.

In practice, the parts being constructed as shown and described, the device is intended to operate as follows: Suppose P to be one of the posts of thefence andQ the fence-wire to be stretched. The latter is secured bymeans `of the grip I to one end of the chain, which is thence passed around the chain-wheel of the device, which latter is anchored to the post By 7o turning the crank-arm in the direction to take up the chain the wire is stretched, and when sufficient tension is thus obtained on the wire the operator slips the loose end of the chain into the fork, as shown in Figs. 1 75 and 2, which permits him to release the handle and secure the wire to the fence-posts. Should one operation of the chain not be su iiicient to stretch the wire, the operator takes a new grip on Athe wire with the loose 8o end of the chain and by turning the handle now in the opposite direction again stretches the Wire, and in this manner he may continue as long as necessary. The operator in this operation may either be making use of the fork to temporarily hold the chain While he takes a new grip on the wire or he may use a pin f, which he placesin a hole g, provided for in the frame in such position that it, engages between two cogs in the gear-wheel, 9o and thereby prevents the same from revolving. Instead of applying the crank-arm directly to the shaft B the operator, if he desires, can secure it to the stub of the shaft G of the gear-pinion, and thereby use greater power, as may be necessary for stretching heavy Wire.

In making wire fences it is desirable that all line-wires be stretched alike, and with my construction this is easily accomplished, as roo can dispense with such aid, as he can trust to his feeling, I make 'the handle c detachable from the leverb and provide coincident holes m n in the crank-arm and lever for securing the handle thereto, and thereby rigidly'holding the parts together, as shown. in Fig. 3. While my construction provides thus an efficient device for stretching fence-wire, it is a general-utility tool, in that it can be adapted for various purposes on a farm, as it is of the general nature of a tackle. One particular use more nearly related to fence-building is that for coiling wire. Thus by providing a coiling-tube, as R, which can be attached to the stub G, the ceiling of the stay-wires used forcertain kinds of wire fences maybe readily accomplished with it. In like manner asmall grindstone, havingr means for attaching it upon the stub G, may be readily operated with it. To adapt it for these various purposes, I provide the armrJ with one or more bolt-holes o and with some spurs p on the under side, so that it may be readily fastened down on top of a bench.

What I claim as my invention is'- 1. In a wire-stretcher, the combination of the supporting-frame having means at the rear end for anchoring it vto the fence-post and provided at the front end with a fork forming a chain-stop, a chain-pulley journaled in the frame and provided with meansY for revolving it in either direction, and a loose chain coacting with said-fork and on said. shaft, an internally-geared wheelon said shaft, a gear-pinion engaging with said gear-wheel, a loose chain adapted to form a chain-gear with said-chain-wheel and provided with Wire-grips at both ends and a z chain-gear with said chain-wheel and a crankhandle adapted to be interchangeably se- ;cured tothe shaft of the chain-pulley or to Ithe shaft of the gear-pinion for imparting motion thereto in either direction.

. 4. In awire-stretcher, the combination of the supporting-frame havingpmeans at the rear end for anchoring it to the fence-post and provided at the front end with a fork forming a chain-stop, a -chain-pulley journaled in the frame and provided with a crankarm for revolving it in either direction, and a loose chain coacting with said fork and adapted to form with said chain-pulley a chain-gear and provided with Wire-grips at both its ends whereby it may be used alter= nately at each end of the chain, the aforesaid crank-arm having a lever h pivotally se cured thereto and arranged to form a tension indicator for the stretcher.

`In testimony whereof I affix my signature in presence of two witnesses.
