JAMES M. ROBERTS, OF ST. JOSEPH, MISSOURI.

WIRE-STRETCHER.

Specification of Letters Patent.

Patented Jan. S, 1918.

Application led September 15, 1917. Serial No. 191,637.

To all whom z'z may concern Be it known that JAMES M. Renners, a citizen of the United States, residing near St. Joseph, in the county of Andrew ank State of lvlissouri, have invented certain new and useful Improvements in Wire-Stretchers, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relatesto improvements 1n wire stretchers and staple pullers, combined; and the objects of my improvements are, first; to provide a simple, substantial and durable wire stretcher, which shall be held in position, against a fence post or similar object by the tension of the stretched wire, thereby leaving both hands of the operator of the stretcher free, while driving a staple in said post, for holding the stretched wire in place, second; to so construct the stretcher, that it shall be adapted for use in stretching both fence and telephone wires, third; to so form the gripping members that the thereby gripped wire can not escape from between said members while it is being gripped, fourth; to provide a staple puller, formed with the body of the wire stretcher, for pulling staples from posts and the like, fifth; to so form an implement of this class, that it shall be compact and cheap in cost of manufacture.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which Figure l is plan View of the stretcher and l a transverse section of a fence post, with a fence wire stretched thereagainst. Fig. 2 is rear view of the stretcher, seen in Fig. l. Fig. 3 is an end view of the stretcher seen in Fig. l, looking toward the right. Fig. 4 is a side view of the stretcher with the parts in position stretching a telephone wire.

Referring to Figs. 1 and 3, the body 1, of the stretcher, has handle 2, fulcrum points 3 and grip members t and l', formed therewith. Said members have the projected edges 4 and la formed therewith, which overlap the adjacent edges of the oscillatable grip members 5 and 5 respectively. Said oscillatable members have wire guides 6 and 6', respectively formed therewith.

Body 1 has the two mortises l', formed therein, in which grip members 5 are oscillatably mounted. One end of each of said members is pivoted on bolt 7, which is passed through said mortised portion of said body.

Grip members 4 and 5 grip the fence wire 8, for stretching the same across the face side of post 9.

Cant hoolr 10 has ratchet teeth 10 formed on one edge thereof, which engage lug 10. Said lug is formed in the mortise 10, which is formed through body 1. hook adjusting means, whereby the reachv of said hook is adjusted.

rlhe bifurcated brace 11 has the upper ends of its upper bifurcations pointed for adapting the same to be engaged with the face side of post 9. The lower bifurcations of said brace each have a slot 11 formed therethrough, along one edge of which the ratchet teeth ll are formed. Said teeth engage bolt 7 which forms brace adjusting means, whereby the reach of said brace is adjusted.

Bolt 7 is secured in place by the two collars 7 which are secured on the ends of said bolt by pins 7.

Claws l2 are secured on one end of body l, and are adapted to be forced between wire 8 and post 9 while astride staple 13, for drawing said staple from said post.

Body 1 has bolt 14 formed therewith and extending through niortises 1', which bolt is engaged by the ratchet teeth 10', of cant hook 10, as seen in Fig. i; for use in stretching a telephone wire 15, as hereinafter described.

In operation, the operator places fulcruni points 3 against post 9, and passes the free end portion of wire 8, between grip members e and 5. He then presses the wire guide G toward said wire, thereby pressing the toothed edge of member 5 in close contact with said wire. Thereafter, by handle 2, with one hand, he swings body 1, fulcrumed on fulcrum points 3, until said wire is tightly'stretched. He then, with the other hand adjusts the reach of cant hook 10, as required, and thereafter drives the point of said hook into post 9, after which the tension of wire 8 holds the wire `stretcher in place. Said operator, then, with the usual tools and the use of both hands, drives staple 13 into post 9, for holding said wire in place.

He then releases cant hook 10 from said post and by wire guide G, moves member 5 This provides fromV contact with wire 8, after which the operator repeats the described operations, for securing said wire to another post.

i/Vhere the shape of the post is such as to render cant hook l0 inadequate to hold .the parts in the position shown in Fig. l, the pointedy ends of brace ll are swung into engagement with the face of the post, for additionally bracing the Wire stretcher against the strain of wire 8.

When used as a telephone wire stretcher, the parts are placed in the position seen in Fig. 4, with fulcrum points 3 and hook 10 engaging the surfaces of cross arm 16.

Similar operations are performed with grip members 4 and 5 and the -wire guide 6, for engaging wire l5 'between said meinkbers, after which said wire is stretched adjacent to insulator 17, as Vpreviously described. Said wire is then secured in the nsual'manner, by a tire wire, (not shown,) to insulator 17. The wire stretcher is removed from the position shown in F ig. 4, by performing releasing operations, similar tothe ones already described.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent is In a wire stretcher, a body adapted to be used as alever; a pair of fulcrum points formed with said body, said points being adapted to act against a post as a fulcrum for said body; grip members carried on said body for gripping a'wire; a handle on one end of said body whereby the latter is swung` on said fulcrum points for stretching said wire; holding means connected with said body, the freepend of said holding means Copies of this patent may he obtained for ve cents each, by addressing the Commissioner being' adapted to engage the side of said post for holding said body against the strain of said stretched wire; and auxiliary holding` means comprising a vbifurcated brace adjustably pivoted on said body, the ends of the bifurcations of said brace being adapted to -be ldriven into said post for assisting inholding said body against the strain of said stretched wire.

2. In a wire stretcher, a body. adapted to be used as a lever, a pair of fulcrum points formed with said body, said points being adapted to act against a lfixed object as a 'fulcrum for said body; a handle formed on one end of said body; wire gripping` inembers connected with the opposite end of said body for gripping a wire, said body being adapted vto be swung` by said handle and thereby move said grip members for stretching said wire; a mortise formed in said body; a cant hook detachably held in said mortise; a pair of Yother mortises formed in the intermediate portion of said body; a grip 'member oscillatably mounted inv each one of said mortises'; arbolt lformed with said body extending through the last mentioned mortises, said cant hook being adapted to be removed from the iirstmentioned mortise and to be passed through one of the last mentioned two mortises and to have its hooked end engaged with said fixed object for holding said body against the strain of said stretched wire; and ratchet teeth formed on one edge of said cant hook said teeth being` adapted to engage said bolt for adjusting the reach of said hook.

In testimony whereof I affix my si gnature'.
