JOI-IN J. SEAL, OF TATUM, NEW MEXICO.

WIRE STRETCHER.

Application filed. June 5, 1923.

To all whom t may conce/m2.'

13e it known that I, JOHN J. SEAL, a citi'- Zen of the United States. residing at Tatum, in the county of Lea and State of New Mexico, have invented cei'tain new and useful improvements in 1Wire Stretcher-s, of which the following is a speciiication. y

In carrying out the present invention, it is my purpose to provide a wire stretcher that may be employed for stretching the ends of a wire whereby the same may be attached to fence posts, the device being also capable of stretching a pair of alined wire links together for permitting the ends of the same to be spliced.

A further purpose of this invention is to substantially simplify the general construetion of wire stretchers. with which 1 am now familiar, my invention embracing at the same time, the desired features of eiiiciency and durability, and one that may be manuiaotured and marketed at small cost.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

ln the drawings forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein Figure 1-is a side elevation of my improved wire. stretcher, positioned for stretching a strand of wire towards a fence post.

Figure 2-is a detail cross section taken substantially upon the line 2-2 of Figure 1, and looking upwardly in the direction of the arrows.

Figure 3is a perspective of one of the wire clamp members employed in conjunction with the invention, and

Figures 4 and -are perspectives of certain elements comprised in the invention.

Referring vto the drawings in detail, my invention comprises among other elements, a relatively elongated operating lever 5, that is flattened at 6 at its upper end. Pivoted to the iiattened portion of said hand lever, and adjacent the lower end thereof at the point 7 is a U clevis 8, that is provided at its closed end with an opening for receiving a forwardly directed rod 9, Figure 5, this rod being headed at one end at 10 for preventing disengagement of the same from Serial No. 643,517.

the clevis, and being provided with upturned hook 11 at its opposite end. This liook is adapted for engagement through the end link of a. chain section 12, the opposite end link of this chain section carrying a hook 13, adapted for engagement in any one of the links of the chain section, Vafter the end of the same has been engaged around a fence post A.

Pivoted at 1l, also to the flattened portion 5 of said hand lever 7, and at a point above the clevis 8 is a well-known form of clevis 15 that is carried by one end link of a chain section 16, which extends in a direction opposite to that of the chain section 12. The opposite end link of this chain section carries a wire clamp, designated generally 17. As more clearly shown in Figure 3, this wire clamp embodies a round tapered post 18 flattened at its smaller end at 19 and provided with an opening 20, for the reception of said end link of the chain section 16. Slidable over this tape-red post 18 is a collar 21, the opening therein being relatively smaller than the diameter of the post 18 at its outer end, it being of course understood that when it is desired to stretch the wire strand B and after the chain section 12 has been engaged over the post A, this collar 21 is moved rearwardly upon the post 18. after which the said wire strand is engaged through the opening of the collar and bent downwardly as shown in Figure 1. A swinging movement of the hand lever 5 in a direction towards the left of Figure 1, will occasion a` binding of the wire strand between the post and collar of the clamp, for thereby effectively stretching the wire upon a continued swinging movement of said hand lever,

As a means for locking the hand lever in a position for maintaining the wire strand in a stretched position, the upper end of said flattened portion 6 has pivotally secured thereto at 22 a clevis 23, that extends in a direction similar to the direction of the clevis 8, and is similar in all respects to this clevis. The same is also provided with an opening for receiving a rod 24, one end of which is also headed for preventing disengagement of the same from the clevis, while the opposite free end thereof is formed with a downwardly extending hook 25, adapted for engagement with one of the links of the chain section 12, after the said wire strand B has been stretched.

The chain section l2 carries adjacent the end provided With the hook 13, a Wire clamp I7 that is similar in all respects to the Wire clamp 17, the same adapted for receiving the end of a strand of Wire opposite to the wire strand B, whereby the two strands inay be brought together upon a rocking movement of the hand lever 'lor permitting the ends ot the same to be spliced.

In view ot the above description, it is believed by nie that the operation and advantages ot a Wire stretcher ot this ,charac- -ter Will be readily appreciated by those skilled in the art. and even though I have herein slioivn and described the preferred embodiment ot' iiiy invention, it is nevertheless t0 be understood that minor .changes may be made therein. Without departing Jfrom the spirit and scope of the invention as claimed.

the larger end of said post, the tapered surface of said post being,- unbroken throughout its circumference, and a` collar Islidably mounted upon said post and having' a cen-l tral opening which ,is vless in diameter than said larger end and discular head, 'said collar being rectangular 'in transverse section -to provide opposed fiat impact surfaces. and

a fiat peripheral Wall surrounding said opening.

In testimony whereof I affix my signature.

.JOHN Jj SEAL.
