WIRE-FENCE -STRETCHER.

Specification of Letters Patent. Patented luztl. 20, 1917.

Application med october 31, 1913. serial No. 798,565.A

To all whom 'it may concern:

Be it known that I, JACKSON l/VTLLIAMS, a citizen of the United States, residing at Ekron; in the county of Meade and State of Kentucky7 have invented certain new and useful Improvements inlVire-Fence Stretchers, of which the following is a specification.

This invention relates to wire fence stretchers and has for its primary object to provide a device in which the pull on the wires comprising the fence will be substantially simultaneous and uniform.

Another object resides in the provision of a simple and efficient anchoring element or stand which is detachably engaged with the earth so as to be placed in proximity to the fence on which the pull is to be exerted.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claim forming a part of this s eciiication. v

Re erring to the drawings :n

Figure 1 is a side elevation of the anchor stand and operating lever constructed in accordance with my invention;

Fig. 2 isa front elevation of the wire clamping member;

Fig. 3 is a sectional vi'ew taken on the line 3-3 of Fig. 2;

Fig. 4 is a detail enlarged front elevation of one of the lever gripping jaws; and

Fig. 5 is a side elevation of the wire fence clamping member showing the same in a closed position.

In the drawings wherein is illustrated the preferred embodiment of this invention an anchor stand-10 is provided which in the present instance comprises a pair of metal straps 11 each of which has an intermediate portion thereof formed so las to providek a support as indicated at 12 while the extreme 'ends of each is turned at obtuse angles so as to provide feet 13 said feet being provided with apertures which are adapted for engagement with securing pins 14, each of the securing pins in the present instance comprising a single strand of wire which has one end thereof bent at right-angles to the body so as to limit the movement of the same in the earth, with which the anchoring stand, through the medium of the feet 13, is engaged. Secured to these supporting portions 12 of the straps 11 is a plate 15 which is detachably secured to the portionsV 12 through the medium of bolts 1G or other suitable detachable securing means, said plate being provided for supporting a pair of yokes 17, each of said yokes comprising a sheet of metal formed so as to provide an apertured ear 18 at one end, and having portions 19 thereof turned outwardly at rightangles to the. body on the opposite end through which the yoke is secured to the plate l5. Y

Fulcrumed between the yokes 17 is an actuating lever 20 which is fulcrumed or pivoted adjacent one end thereof between the ears 18, the apertures being provided in said ears so as to aline with a transverse opening in said operating lever through which a fulcrum or pivot pin 21 is engaged. Arranged on the lever 2O adjacent its pivotal connection with 'the yoke member 17 are a pair of gripping jaws 22 each of which is formed from a metallic plate having the opposite ends thereofbifurcated, the branches of the bifurcation as indicated at 23 being pivotally engaged with the lever 2O while the branches of the bifurcation 211 which are formed at the opposite end of the gripping jawA are preferably beveled and tapered to a point, said pointed ends being arcuated so as `to provide hooked ends the .function of which will subsequently appear.

In order to prevent the creeping of the anchoring stand on the ground, or earth; which would sometimes be caused when the earth or ground to which the stand is secured is in a soft condition, I have secured in the plate 15 an eye-bolt 25 with which is engaged a chain 26, said chain being secured to a stationary object such as a tree, post, or the like in order to insure the rigidity of the structure during its operation.V

In order to facilitate the stretching of the wire and to provide a step by step movement of thersame, so as to exert a constant simultaneous and Vuniform pull on the wire a suitable clamping element generally designated 27 is provided which is hinged at its opposite ends as indicated at 28, said hinges being secured to the jaws 29 of the element through the medium of screws 30 or the like so that the same may be detached when so desired.

One of the jaws iS provided with a plurality of recesses 31 which are adapted for engagement with studs 32, the latter being carried by the opposite jaw in order to limit the vertical movement of the wiresV duringV the stretching operation, as each strand of wire will be coniined between a pair oi said studs 3Q. Set screws 33 are engaged through the jaws 29 o'f the wire clamping element 27 so as to. snugly engage the wire between said jaws thereby preventingthe slipping of the same when pressure is exerted on the jaws. Each of the jaws 29 is provided with a block 3e through which the set screws 33 are engaged, so as to prevent the displacement of the same which would be caused after a certain length of time due to the pressure exerted thereon by the yokes 35, said yolres having threaded bores, each of the volier having an eye 36 formed thereon which is engaged b v a chain 23T. said chain in turn being engaged by the gripping jaws 23 so thatv when pressure is exerted on the actuating lever 20, the wire clamping element 27 will be moved in a horizontal plane toward the anchor stand l0 in order to simultaneously exert a uniform pull on the wires of the fence which are arranged between said clamp element. ln view of this tact the blocks 34 are preferably formed of metal so as to insure at all Jfinies a rigid and durable structure capable of withstanding the strain exerted thereon.

In operation the clamping aws 29 are engaged with the wire to be stretched. Should the same o barb or strand wire, each strand will be placed between a pair of the stucs 32 thereby limiting the vertical movement of the same lor facilitating the stretching of the wire. The set screws are then actuated causing the jaws to be snugly engaged with the wire which is placed therebetween, and the chains 37 then engaged with the gripping jaws The lever 2O is actuatable in the arc of a circle on the pivot or ulcrum pin 1S so that when the same is operated it causes the wire clamping element 2T to be pei-ated in a horizontal plane. It is seen that each of the links 3T it desired may be engaged with the arcuate biturcated ends Q4; of each ol the jaws l2 so as to provide a step Copies of this patent may be obtained for ve cents each, by addressing the by step movement facilitating the stretching of the fence and eliminating the frequent moving of the anchoring stand l0 as it is obvious that a plurality of the links 37 may be carried by the eyes 36, and the stands 10 placed a suiiicient distance, say approximately four or ve eet from the points at which the pull is to be exerted on the wire, thereby causingthe entire stretching of the wire without moving the stand l0. rlhe positioning of the stand 10 with respect to the clamping element 27 will oi course be according to the fence or wires which are to be stretched.

.it will be understood that the above de scription and accompanying drawings comprehend only the general and preferred embodiment ot my invention and that various minor changes in details of construction, proportion and arrangement of the parts may be made within the scope of the appended claims and without sacriiieing any of the advantages of my invention,

Having thus fully described my invention what 'I claim as new and desire to secure by Letters Patent is z A device of the character described including a pair oit clamp members provided with openings therein, blocks positioned in said openings and having transversely extending openings, yolres engaged with said blocks and provided with threaded openings registering with the openings of the blocks, means extending through 4the openings of the blocks and screwed into the openings of said yokes for holding the latter from displacement, and means extending from said yolres to be placed in connection with a power element whereby fence wires held between said clamp members may be stretched.

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