Patented July 17, 1906.

Application filed September 28,1906. Serial No. 280.497.

To all whom it may concern:

Be it known that 1, ANDREW H. DE GROFF, a citizen of the United States, residing at Little Genesee, in the county of Allegany and certain new and useful Improvements in Wrenches, of which the following is a specification.

For a full description of the invention and the merits thereof and also to acquire a to knowledge of the details of construction-of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view of a Wrench .15 embodying the invention, the jaws being separated at a maximum ad'ustment. Fig. 2 is a side elevation, the jaws eing shown'adjusted so as to occupy positions as near each other as admitted of. Fig. 3 is a perspective -2o view of one of the jaw members. Fig. 4 is a erspective view of the other of the jaw memfhers. Fig. 5 is a transverse section through the pivot of thejaw members, showing the means for preventing rotation thereof.

Corresponding and like parts are referredto in the following description and indicated in all the views of the drawings by the same reference characters.

This invention embodies a novel form of wrench of the type designed particularly for use in operating on pipe and a so for applying and removing nuts from bolts.

The invention resides in the general simplicity of the device and in the novel details 3 of construction, which will appear more fully 0 nated 3.

as the description proceeds.

A wrench embodying the invention comprises two pivotally-connected members 1 and 2, the pivot of said members being desig- Each of the members 1 and 2 comrises a jaw, a shank, and a handle integrally formed. The jaws of the members 1 and 2 are designated 4 and incline at an obtuse angle from the shanks thereof. -The working faces of the jaws 4 are roughened, as shown at 6. The members 1 and 2 are of peculiar form, the handles and shanks being flat, but arranged in planes. at approximately a right angle to each other. 11 other words, the

50 shanks of the members 1 and 2 are cut away at adjacent sides, as shown at 7 and 8, respectively, sothat they fit snugly together, occu- At the same time the above construction is such that the handles 5 of the members 1 and 2 are in approximately the same plane. The pivot 3 isfiat at'opposite sides, as shown at 12, being provided with heads 9 and 10 at opposite ends. A pin 11 passes through the shank of the jaw member 1 and engages the head 10 to prevent rotation thereof. The member 2 is provided with two pivot-openings 13, connected by a slot 14', the slot being of substantially the same width as the narrower portion of the pivot. The form of the pivot 3 affords adjustment of the jaw memers 4 with regard to each other, which is common in the prior art, the member 2 being adapted to be turned into a position admitting of longitudinal movement thereof with regard to its pivot, and this operation will admit of disposition of the pivot in either of the openings 13 in a manner which will be obvious.

One of the members of the wrench is providedwith a stop-shoulder which cooperates with the-pivot-fastening to limit the closing of the handle members when pressed together after the movable member has been adjusted,- so as to obtain a large space between the jaws thereby preventing injury to the hand which would result if the handle members were permitted to come together. As shown, the member 1, provided with the pivot-fastening 12 the stop-shoulder 15. tively stationary and the member 2 movable.

When the jaws are close together, as indicated in Fig. 2, the stop-shoulder 15 does not erform any function, since the handle memers cannot be pressed together because of the close relation of the aws. When the is likewise supplied with The member'l is rela member 2 is moved so as to se arate the jaws of thewrench, as indicated in ig. 1, the stopshoulder 15 engages with the lower edge of the movable member'2 and limits the closing of the handle members when pressed together, as will be readily comprehended.

Having thus described the invention, what is claimed as new isj A wrench comprising similarly formed members, each provided at one end with an offstanding jaw extending forwardly at an obtuse angle, a flattened handle at the opposite end and an intermediate flattened shank, the handles being offset from the shanks, one of said members having a stop-shoulder at the juncture of the handle and shenk and In testimony whereof I afiix my signatui provided wgith a flattenid ivot, Eng the in presence of two Witnesses.
