fication, reference being had to the accomvide a wire stretcher which is capable of stretching wire, either. from the right to the left, or from left to right.

Another object of the invention consists in the provision of a clamp, and an intermittently operative mechanism swiveled thereto, whereby post, in case the post should happen to twistwhen stretching the wire, and furthermore, by the: provision of the swivel connection, the stretching machine may be kept in alinement with the wire, so that the wire may at all times travel straight into the machine.

A further object of the invention is to provide a machine of this kind, so used for stretching wires, as to permit the wire to be nailed or otherwise fastened to the same post, from, which the wire is stretched, thereby saving much labor and inconvenience, by doing away with having to brace two posts. I a

A still further object of the invention. resides in the provision of a stretcher that willprevent the twist orturn of the post, before the stretcher is detached from the post,thereby leavingthe wire stretched the same as whenthe-machine stretched it.

The invention still further aims to, provide a stretcher which is capable of stretching the wireunder all conditions, such as inside of sharp fence. corners, in brushor among trees, asthe cperating. lover of the Specification of Letters Patent.

machine can be manipulated in either a vertical or horizontal position, or any degree between such positions.

The invention additionally aims to provide a stretcher which can be easily and very quickly attached to a post, and will complete stretching the wire up to the corners and ends of the fence.

. While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and

the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The inventioncomprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

Fig. 7 is a detail perspective view of the frame 9, and showing the detent spring 37, and also the detent releasingdevice,

Fig. 8 is a detail perspective view of the detent releasing crank element 40, and;

of a single piece of metal bent upon itself to form a rectangular loop 5, which receives the bar 2 of the clamp l. The opposing parts of the clamp 4 are riveted together as indicated at 6, and the end portions of the opposing parts terminate in claws 7, adapted to bear into the fence post and cooperate with the opposing plate 3, to hold the clamp securely and firmly to the post. A set screw 8 is threaded into the loop of the clamp 4 to hold the clamp in different adjusted positions on the bar 2.

A U-shaped frame 9 is swivelly connected to the plate 3 by means of the headed pin '10, the head of which is counter-sunk in one the shaft 13, and is counter-sunk in the outer face of one of the sides of the frame 9 (which is U-shaped) to prevent the shaft from rotating, whereas the wheel is rotatable upon the shaft. A cotter pin 18 passes transversely through the opposite end of the shaft 1 3 to cooperate with the dowel pin to prevent axial movement of the shaft. The ends of the sides of the frame 9" are bifurcatedas shown at 19, and are provided with forks 20 caused to be formed by the bifurcations. Removably engaging between the forks are anti-frictional rollers or sleeves 21, which constitute bearings for the shaft 22. Feathered or splined to the shaft 22 as at 23 is a wheel 24, which comprises three sections 25, 26 and 27, which are fastened together by the transverse pins 28. The section 25 of the Wheel is provided with ratchet teeth 29, and the section 26 is smaller in diameter than the section 27, and is provided with gear teeth 30. The section 27 is also provided with gear teeth 31, which are adapted to mesh with the gear teeth 16 of the wheel 14, when the wheel- 24 is moved toward the wheel 14. Pivoted' upon one of the sleeves 21 to move relativelythereto and positioned adjacent the sideof the wheel 24 is the'flat end 32 of the lever 33. Mounted on one face of the lever 331s a dog 35, adapted to engage the ratchet teeth 29 of the section 25 of the wheel 24,]so as to impart an intermittent movement to the wheel.

A spring detent 37 has the terminal of the curved. portion counter-sunk in and secured to one endoff the frame 9. The spring detent extends ina' direction with the frame 9 and terminatesin a lug 38, which is designed to cooperate with the ratchet teeth of the section 25 of the wheel 24, to prevent retrograde movement of the wheel, as it is intermittently moved by the manipulation of the lever. An arm 39 is fastened rigidly to one side of the frame 9, and mounted in a hearing of said arm is a crank element 40. This crank element has a projection 41, which is adapted to cam against the spring defeat, in order to disengage the lug of the spring detent from engagement with the ratchet teeth of the wheel 24.

In the operation of the machine, it is first mounted upon the fence post and secured rigidly in position by means of the clamp 1, although the frame 9 is capable of swivel movement. The usual fence wire reel is arranged as shown in Fig. 1, with the fence wire, which may be barbed or plain, passed upwardly over the wheel 14, and down wardly between the wheel 14 and the teeth 30 of the wheel 24, and then over the gear teeth 30 between the ratchet teeth and the gear teeth 31, and then adjacent the fence post, and to the other fence post, as shown. In order to stretch the fence wire, the lever is moved in the direction of the arrow (1. which will impart an intermittent motion to the wheel 24, stretching the fence wire.

Each movement of the wheel 24 will tension the fence wire, and by means of the spring detent, the wheel 24 is prevented from retrograde movement. Should the wire be stretched to an excess and it is desired to release the tension of the wire, the detent may be disengaged from the wheel or ratchet 21', and then by grasping the lever 33 and hold ing the same while it moves backward, the wire may be allowed to slacken. lVhen the wire is slackened enough, the detent will he allowed to again engage the ratchet to hold the same. The spring tensioned dog coinprises a rod 35 mounted in guide eyes 36" and 37 which are carried by one side of the lever 33. A coiled spring 38 is in surrounding relation to the rod or dog 35 and is interposed between the guide eye 36 and a cotter pin 39 which is arranged transversely of the rod 35. The cotter pin is spaced slightly from the eye 37 so that the spring 38 may tension the rod to hold its end 40 in en gagement with the teeth of the ratchet. The ends of the rod opposite its end 40 terminates in ahook 4 which may be engaged by the finger of the operator, in order to disengage its end 40" from the teeth of the ratchet.

After the wire has been stretched, it is not released until it is fastened to the fence post, and it is the aim to fasten the fence wire to the same post from which the wire is stretched, thereby saving much labor and inconvenience.

In order to additionally fasten the clamp 1 to the fence post, a short nail or staple may be driven through any one of the several openingsior holes? in the plate 3, and then into the fence'post, asindicated at42.

I The wire stretcher maybe connected to the fence post so that thefence wire may be nailed or fastened to the very topof the post,

if desired. Also the wire maybefastened to theextreme lower: portion of the post. This maybe accomplished by excavating the ground around the post, so as to countersink thestretcher, sothat the fence wires may be stretched immediately from aclose position to the ground and disposed close together, in order to prevent the passage of hogs, rabbits and the like. The stretcher can be easily removed from the post, by pulling outwardlyupon the bar 2, that is after the clamp 4 has been disengaged from the post, thereby causing the plate 3 to extract the nail.

Furthermore, the stretcher will not injure thefence wire, when stretching the same, which is very often the case with all. other stretchers, due to the wire passing around a wheel and causing friction. The present form of wire stretcher may be used for other purposes, such as pulling automobiles back into the roadway at rough places,

and for pulling stumps, posts and trees, or

large bushes. When pulling automobiles back into the roadway, the stretcher may be attached to a stationary object, and after which a heavy cable or chain or the like may be attached to the automobile and passed over the stretcher in the same manner.as the wire to be stretched is arranged,

after which the usual intermittent motion is imparted to the wheel 24. This device can be used also for pulling bushes and hoisting commodities. When pulling bushes or hoisting commodities, the device may be mounted or connected to a pair of vertically arranged spaced stakes, and the cable or chain is then passed downwardly and around the bush and by manipulating the lever, it may be extracted from the soil.

In order to direct the wire back toward the fence post, should the fence post he come twisted, due to the strain of the wire, the U-shaped frame may be moved swivelly, by applying pressure laterally upon the lever in a direction of the fence post. Owing to the swivel connection with the U-shaped frame, it is possible to keep the fence wire at all times in alinement with thefeed wheels.
