PIPE-WRENCH.

Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed June 29, 1912. Serial No. 706,755.

T 0 all whom it may concern:

Be it known that I, VVALrna J. BRIGHT- wnLL, a citizen of the United States, residing at Kilgore, in the county of Gregg and State of Texas, have invented certain new and useful Improvementsin Piperenches, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in wrenches and more particularly to that class of wrenches comprising a pair of crossed pivotally connected levers.

The primary object of this invention is the provision of a wrench comprising a pair of levers having jaws detachably connected thereto.

A further object of the invention is the provision of a wrench which may be provided with a plurality of interchangeable jaws.

With these and other objects in view my invention consists in certain constructions and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a front view of my pipe wrench; Fig. 2 is a side view thereof; Fig. 3 is a section taken on the line 33 of Fig. 1; Fig. 4 is a section of one of the jaw holders; and Fig. 5 is a perspective view of one of the jaws.

Referring in detail to the drawing the numeral 1 designates generally my improved invention, comprising a pair of crossed pivotally connected levers 2. The levers are formed at one end with handle members 3 and have their opposite ends enlarged as at 4 to form jaw holders. Each of the jaw holders is formed with a longitudinal slot 5 and the opposite walls 6 of each holder are connected by a cross bar 7 intermediate of its ends. A similar cross bar 8 connects the walls of the holders at their extremity and on the opposite faces thereof. Jaws 9 are supported in the slots 5 in the holders and each of the jaws is provided with a lug 10 on one end which is adapted to engage the cross bar 7 of the holders and prevent longitudinal movement of the jaws. The intermediate portions of the jaws are arranged between the walls of the holders and engage the cross bars 8 thereby preventing outward movement of the jaws. The ends of the jaws opposite the lugs 10 are curved arcuately as at 11 and provided with teeth 12 to prevent the Wrench from slipping on a pipe or other smooth object, to which it is applied.

Mounted on the outer .sides of the holders are spring members 13 formed at one end with square openings 14 which are adapted to engage the lugs 10 of the jaws. The eX- tremity of the spring members adjacent the openings therein are curved upwardly to provide finger pieces for raising the spring out of engagement with the lugs 10 of the jaws. It is apparent from the drawing that should the outer face of the jaws be struck against an object, the lugs 10 thereof may be disengaged from the cross bars 7 whereupon the lugs will engage the square open ings in the springs, and thereby be prevented from longitudinal movement or displacement from the holders. Should one of the jaws of the wrench become broken it may be easily removed from the holder by raising the spring 13 and disengaging the lug from the cross bar 7 whereupon a new jaw may be placed in the holder.

Any desired number of jaws of different sizes may be used with this wrench and it is apparent that expense to the user will be minimized as only one pair of levers is necessary with any number of jaws.

Having thus described the invention, what is claimed is:

1. A device of the character described, comprising a pair of crossed pivotally connected levers, jaws removably secured in longitudinal slots formed in one end of said levers, lugs formed on one end of said jaws, and spring members provided with openings to receive said lugs mounted on the levers, said spring members adapted to hold the jaws in position.

2. A device of the character described, comprising a pair of levers having longitudinal slots in one end thereof, cross bars connecting said slots, jawshaving lugs on one end arranged in said slots, and spring members provided with openings to receive said lugs, said spring members adapted to hold said jaws in position.

3. A device of the character described, comprising a pair of crossed pivotally connected levers, one end of each of said levers being enlarged to form jaw holders, said jaw holders being formed with longitudinal slots and cross bars adapted to connect the opposite walls of said holders, jaws ar ranged in said slots and bearing against said cross bars, and spring members adapted to hold said jaws in position.

4. A device of the character described, comprising a pair of crossed pivotally connected levers, one end of each of said levers being enlarged to form jaw holders, said jaw holders being formed with longitudinal slots and cross bars to connect the opposite walls of said holders, jaws having lugs on one end arranged in said slots, the said lugs bearing against the cross bars of the holders, and spring members provided with openings to receive the said lugs mounted on said levers, said spring members adapted to hold the jaws in position.

111 testimony whereof I hereunto affix my signature in the presence of two Witnesses.

WALTER J. BRIGHTWELL. Witnesses:

O. G. CHANDLER, L. P. GRIFFIN.
