7 Claims.

This invention relates to new and useful improvements and structural refinements in wire 'stretchers, more specifically, wire fence stretchers, and the principal object of the invention is to provide a device of the character herein described, which may be conveniently and effectively employed for stretching the wire fence preparatory to the securing thereof on the fence post.

A further object of the invention is to provide a wire stretcher which may be quickly and conveniently adjusted to facilitate operation thereof on uneven ground.

Another object of the invention is to provide a Wire stretcher which is simple in construction and operation, and which may be easily manipulated.

An additional object of the invention is to provide a wire stretcher which will not easily become damaged and which is otherwise well adapted for the purpose for which it is intended.

With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the invention, showing the same in use;

Figure 2 is a top plan view of the invention per se, and

Figure 3 is a perspective view of a block used in the invention.

I?) may be increased or decreased accordingly.

The aforementioned fork I3 is downwardly arcuated and the arms l9 thereof are provided at their lower extremities with suitable bearing blocks 2a which, together with further bearing blocks in, constitute what may be referred to as a pair of knuckles 22.

A pair of extension arms 23 are each secured to one of the blocks 2i, each of the extension arms consisting of a pair of slidably telescoped sections 2% and .25 which are adjustably secured together by means of suitable bolts or pins 26. These pins extends transversely through the sections 23 and are selectively receivable in a plurality of apertures 21 provided in the section 25. In this manner, the overall length of each extension arm may be independently increased or decreased, as desired.

' axis of the bore 30.

Like characters of reference are used to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in'detail, the invention consists of a wire stretcher designated generally by the reference character Ill, the same embodying in its construction a tubular member ll, one end portion of which is telescoped in a tubular extension I2, while the remaining end of the member is bifurcated to provide a fork I3.

A suitable fastener, such as a length of chain It, is equipped at the ends thereof with a pair of screw eyes [5, the latter in turn, being selectively receivable in transversely aligned apertures l6 formed in the parts II and 12, as will be clearly apparent.

The chain I4 is adapted to encircle, as it were, the fence post H and is removably retained in position thereon by means of the nuts IS with which the screws eyes are provided. It will be noted that by simply posititioning the screw eyes in the various of the apertures IS, the overall length of the member I l (including the extension It will be noted that the extension arms 23, in effect, constitute continuations of the arms l9, and the free extremities of the extension sections 25 rest upon the ground surface 28, as will be clearly understood.

A block 29, provided with a transversely extending, screw threaded bore 33, is also equipped with a pair of journals 3|. The latter extend in relatively opposite directions with respect to one another and substantially at right angles to the The journals 35 are rotatably positioned in the knuckles 22, as is best shown in Figure 2.

A screw threaded shaft 32, provided at one end thereof with a crank handle 33, is operatively positioned in the bore 30 of the block 29, the remaining end of the shaft being equipped with a swivel box or block 34. The latter, in turn, is provided with a hook 35, and a flexible element such as a length of rope or cable 36 is connected at one end thereof to said hook. The remaining end of the cable 35 is attached in any suitable manner (as exemplified at 31) to the fence wire 38.

When the invention is placed in use, the fastener id is engaged with the bolt E1, the extension arms 23 are placed upon the ground, and the cable 36 is attached to the wire 38, as has already been explained. Thereupon, by simply rotating the crank handle 33, the fence will be stretched through the medium of the cable 36, preparatory to the securing thereof on the fence post, as will be clearly apparent.

The provision of the swivel 34 will, of course, facilitate rotation of the shaft 32 without twisting the cable 36 and it should be understood that the bearing blocks 20 and 2! in each of the knuckles 3 22 are rigidly secured together, so as to prevent the entire device from collapsing in the direction of the arrow 39.

It should be noted, that once the cable 36 has been attached or applied to the fence Wire 38, by rotating the crank handle 33 the wire will be pulled toward post ll, so that the wire may be fastened thereto by nails or the like. To tighten the wire to the adjacent post (not shown), the chain It is disengaged with the first post and re-engaged with the second post, by adjusting section l2 relative to section II, whereby the device may be used without disengaging the cable with the wire 38.

Finally, the longitudinal adjustment of the extension arms 23 will permit the same to be independentiy lengthened or shortened, so as to facilitate operation of the device on uneven ground.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof'at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
