ABSTRACT:
In a wrench for use in gripping particular workpieces or hardware, such as nuts, pipe, or the like, a handle means has formed at its upward end a fixed jaw, a movable jaw slidably mounts to the shank portion of the handle means for the purpose of adjusting the setting of the wrench. The gripping surfaces of both the fixed jaw and movable jaw are arranged substantially parallel in alignment, and each of said surfaces is arranged at an acute angle of less than 90.degree. with the handle means of said wrench. The movable portion of the wrench is provided with a series of teeth or serrations that are disposed for engaging oppositely disposed teeth formed on the inner surface of the shank portion of the wrench handle, and in this manner the movable jaw may be fixed in a particular setting for gripping a particular workpiece to be manipulated. A leaf spring provided intermediate the outer surface of the shank and the contiguous surface of the movable jaw normally biases the aforesaid sets of series of teeth together, but by the exertion of force upon the back side of the movable jaw the teeth may be disengaged for allowing for the slidable movement of said jaw.
