WIRE STRETCHER.

' Application filed June 12, 1.919. serial No. 303,578.

To allfwhomtma'y concern: n

Be it known that I, ANDREW E. TRINKEL, a citizen of the United States, residing at Jeffersonville, in the county of Clark and State of Indiana, have invented certain new and useful Improvements in a Wire Stretcher, of which the following is a speci-` This invention relates to wire stretchers and the primary object is toprovide a device especially adapted for operation in conjunction with a movable pull chain and a fixed anchor chain.

One of the objects of the invention is to provide an implement which may be connected with the anchor chain and which will be adapted to engage the links of a movable pull chain so that the operating lever mayk be actuated to alternately change the position of the link engaging members of the implement whereby a pull on the chain may be accomplished when the actuating lever 1s moved.

A further object of this invention is the provision of a ldevice of this character which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of the device constructed in accordance with my invention.

Figure 2 is a perspective view of the implement.

Referring to the drawings, wherein is illustrated the preferred form of my invention, in which like numerals of reference indicate like or corresponding parts throughout the several views, the stationary post 1 is provided with an anchor chain 2 which is connected as indicated at 3 to one end of a bar 4. The opposite end of the bar is twisted to provide the forwardly projecting fiat arm 5 the terminal of which is curved upwardly and notched as indicated at 6 to form the bifurcated fork 7 The notch is adapted to receive one of the links of the movable pull chain 8 which is equipped with a clamp 9 adapted to engage the fence wire 10. Pivotally mounted on the bar 4 is a lever 11 which is equipped with a handle 12 and is adapted to extend abovethe movable pullv chain 8 when the device is in operative posi-l4 tion. `It should be pointed out in 'this connection that the movable pull chain may be disposed above the anchor chain 2 as shown to advantage in Fig. 1. At a point on the lever 11 above the pull chain is a pivot pin 13 connectedto an arm 14 which has a claw 15 formed lat its end, similar to the claw 7. This claw 'is also adapted to engage one of the links of the pull chain 8. It is particularly pointed out that the arm 4 is curved as shown sothat the end 3 will be held by the anchor chain 2 into close proximity with the pull chain 8. The opposite end of the pull bar 4: having the extension arm 5 thereon is urged up into engagement with the link of the chain 8 by virtue of its connection with the lever 11 and it will be noted that the claws 7 and 15 are curved to permit them to slide over the links of the chain when moved out of gripping position.

In operation, the chain 2 is secured to a post 1 and the fork 7 engaged with a suitable link of the chain 8, the latter having one end clamped to the fence wire 10 as illustrated in Figure 1 of the drawing. The chain 8, it will be noted passes between the claws 7 and 15 and transversely of the lever so that the free ends may be held in the hand. By

swinging the lever forward to the position shown in Figure 1 of the drawings the cla-W 15 may be engaged-with a link of the pull chain 8 and upon reversal of the lever the Claw will draw the chain over the claw 7 in the direction of the post; this pulling continued as long as it is possible to swing the lever backward. When the lever has been pulled back as far as possible, it may be shoved forwardly again for repulling the chain claw 15 sliding easily over the chain links until the lever is reversed. The claw 7 will prevent the chain 8 from pulling loose when claw 15 is released therefrom by reason of the fact that the horizontal links of the chain are prevented from passing through the opening in the claw. By reciprocating the lever in the manner thus described a continuous pulling operation is thus performed.

The foregoing description and accompanying drawing have reference to what might he considered to be the approved or preferred form of my invention.y I desire it to be understood that I may make such changes in the construction, combination and ar- A. wire stretcher comprising a relatively long bar, a relatively short bar, eachof said.

bars being formed from a flat lstrip of metal twisted' intermediate their ends toy provide a body and a right. angularly disposed shank,

inwardlybent chain engaging:- claws formed on the forward terminals `of the'bodies of thefbars, the shankof'the relativelylong barl extending rearwardly ofthev shank of the relatively short bar, anV anchoring member secured to the rear end ofy the* extended v shanksof therelatirely long bar; and aniopV- erating lever including a handleand a bifurcated portion defining a pair of spaced arms, the lower terminals of the arms straddling the shank of'thevrelatively long member at a point intermediate yits ends, means pivotally securing the arms to the last mentioned shank, the rear terminal of the shank of the relatively short bar being disposed between the arms above the shank of the relatively long bar, and meanszpivotally securing the shank ofthe relatively short bar'to4 said arms.

In testimony whereof I aflix my signature in presence of two witnesses. f
