WIRE STRETCHER.

Application led August 17, 1922. Serial No. 582,448.

T o all whom t may concern.'

Be it. known that I., GEORGE A, LOVATT, citizen of the United States, residing at Boulder, in the county of Fremont and State of kVfyoming, have invented certain new and useful Improvements in Wire Stretchers, of which the followingk is a specification. Y

My invention relates to improvements in wire stretehers.

An object of my invention is to provide a wire stretcher, adapted to be connected to a fence post or the like, and to stretch a wire so as to draw the wire past the post to which itis attached, in order that the wire may be stapled to the post ina convenient and eflicient manner.

A further object of` my invention .is to provide a wire stretcher, which maybe used to splice broken wires and to repair barb or other wire fences; also in the'provision of simple means forA connecting Ytogether the ends of wires where it is essential Vthat said ends be drawn together by positive means, and held during the operation of twisting or otherwise fastening the separated ends.

A still further'object of my invention is to provide a wire stretcher, that is strong, durable, simple and inexpensive in construe# tion, and that is well adapted to the use for which it is designed.

Other objects and advantages of the invention will become apparent during the Qourse of the following description.

1n the drawings, forming a part of the speeilication andV in which like numerals are employed to designate like parts throughout the same-V Figure 1 isa top plan view illustrating my device in use.

Figure 2 is a sideelevation of the same,

Figure 3 is a fragmentary section of the same,

Figure 4 is an end elevation of apparatus embodying my invention, and Y p Figure 5 is a section taken on line 5-5 of Fig. 1 looking in kthe direction of the arrow.

In the drawing where for the purpose of illustration is shown a preferred embodiment of my invention the numeral 10 designates the body of my invention, formed from two pieces of material and held in spaced relation to each other, by means of pins 11.- A pair of guide plates 12 are secured to the side plates 10, and are adapted 13. The rack vided with, locking Ineens 16 te reetret the movement of said rack bar. The opposite end et, theraek. bar 13 ie provided with e wire engaging element 17. The .Wire en gaging element 17 comprises washer 18 having a serrated falce threaded shaft 22, having a movable jaw 19 mounted thereon said jaw 1 9'havingVv a serratedface, a Washer mounted next to the movablejaw 19,and a thumb nut 21 which is adapted to rotate thereby moving the movable jaw 19 and clamping a wire between jaws 18 and A lever socket 2,3 is pivoted to thevbody 10 by means of a bolt 24. Pivoted to the lever socket 23 is a pawl 25, said paWl being pivoted to the said socket lever by means of a pin'26. YThe body portion 1Q is provided with upstanding ears 27 to which is pivoted a second pawl 28 by meansof a pin 29. The pawl 28 is so situ-ated as toy over.V lie the Paul 25 Seid Pewl 28 terminating in` a lever 30 so that when the lever .3Q 'is depressed it willcome in contact with the pvavvlr 25 thereby 'disengaging the pawl 2 8 andpawl 25 from'the' rack bar 13. Thepawl 25 is normally held infcontactwith the rack bar 13 by Imeans of a spring 31, which is carried on the under side of the pawl 28, A pin 32 mounted between the npetendina ears 27 is adapted to carry a spring whichj` nellnnlly heldethe `and 28 in engagement with the teethy 15 cfg the rack bar Y'13.

The body'lO, is ,provided withafsecondy wire engaging element 34 which4 'is constructed fsiinilanto the wirev engaging' el e ment 17. f

Carried.- by Ineeneef erin ,35 ie e elevsr 36 which isconnected to 'the chain 37. A

similar clevis 39 is mounted in spaced rel lation te the @levis 36 en thebedy 1.0 by Ineens ef a. pin-3,8. The. ellain 4Q' earriee e inet/member 4.1. .Whieh ie nrevdediwlth a hook 42 lwhich is adapted to engage one of4 the links of the chain 37. It will thus be seen that this chain is adapted to engage or encircle a fence or the like, and may be made tight by rotating the jack handle 43 which will cause the internally threaded sleeve 44 to ride on the threaded shaft 54'. The body 10 is'provided with any suitable form of prong 46 which will penetrate a ak stationary the chains 37 isl wooden post or the like which will further tend to hold the wire stretcher rigidly on the post to which it is mounted. An operating lever 46 is adapted to be receivedy within the lever socket 23 and is provided at one end with a suitable wire kworking implement such as a staple puller, wire stretcher or nail puller 47.

-In use my improved wire stretcher is placed against the post where it is desired to put. the wire,- around the post and one of the lengths of caught in the hook 42.

Screw 44 down close to the washer `43 in order thatl there will be suicient room to operate the jack v43. The jack 43 is operated Vso that the stretcher will be held in a rigid position during the wire stretching operal tion.' Press the thumb against the lever 30,

which will engage the pawl 25 thereby disengaging the pawl 28 andv 25 from the teeth 15 of the rack 13. Pull the rack bar 13 in the direction of the arrow as far back as pos-V sible. Clamp the wire between the

clamping jaws

18 and 19 ofthe wire clamping member 17. Insert the lever 46 in the lever socket 23 and oscillate the same. It will thus be seen Ythat when the lever 46 is moved in the direction of the arrow, the pawl 25 will engage, one of the teeth 15 of the rack bar 13,*v thereby causing the rack bar to be moved in the direction that the lever 46 is rocked. It will be seen that the pawl 28 will slide over the teeth 15 and fall into the notches,

- thereby holding the body 10 on the wire in position until the lever has been moved to the right again and the operation of moving the lever 36 in the direction of the arrow insuring the engagement of the pawl 25 with the teethl of the rack bar 13, by reason of the pawl 28, thereV is no possibility of the wire slipping when a new grip is being gotten by the pawl 25. When the rack bar 13 has been moved to about approximately the position as isshown in Fig. 1 and it is desired to obtain anew grip on the wire, the free end of' the wire is clamped in the second clamping member 34. The clamping member 17 is then unloosened and the rack bar is moved in far as possible, is again clamped and the clamping member 17 on the wire, and the clamping member 34 is disengaged from the wire. It will thus be seen that I have devised a device whereby a strand of wire or fence may betightened with no possibility of the wire and the chain 37 is circled the direction of the arrow asV slipping either during the operation of my device or in the process of securing a new grip on the wire.

To make a splice, where a strand of wire has become broken, pull the rack bar 13 out as far as possible and put one end of the wire in the clamp 34, and the other end of the wire in the clamp 17. It will thus be seen that by oscillating the handle 46 the broken ends of the wire will be pulled together and overlapped a sufficient distance to allow the twisting thereof, and thereby reunite the saine. To tighten a wire where the wireis not broken but is merely slack, put the stretcher on as described above, and pull the wire taut, cut the wire and tie the loose ends in same manner as above.- It is to be noticed that the clamping member pulls the wire at a point beyond where wire is to be fastened to the post, so that there is no slack whatever after the wire has been fastened to the post.

vIt it to be understood that the form of my invention herewith shown and described, is to be taken as a preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the sub- Joinedv claim.

I-Iaving thus fully described my invention what I claim is A tool comprising a body including a pair of spaced parallel sections, a pair of spaced parallel guide plates disposed in the body, an operating lever including an inner yoke shaped end fitted between the sections of the body and the guide plates, means pivotally securingthe lever to the plates and the sections of the body, transversely extending guide pins arranged across thebody connecting the sections thereof together, a rack bar slid'ably mounted in the body between the guide plates having a longitudinally eXtending slot therein for receiving the guide pins, means carried/by the lever for moving the rack bar in a step-by-stepmovement in the body, and wire clampingmeans carried respectively by the body and rack bar.

In testimony whereof IV aiiiX my signature in presence of two witnesses.
