Abstract
252,523. Evans, S. L. April 28, 1925. Sliding-jaw wrenches; handles. -The sliding jaw member 6 has an arcuate recess 5 engaged by a correspondingly shaped cam 4 on the end of a lever 1 connected by a pivot pin 3 to the head 2 carrying the fixed jaw 10. Stops 8 on the sliding jaw member coact with shoulders 9 on the handle to limit the opening and closing movements of the jaw. A removable pivot may be provided for the handle so that the handle may be reversed to facilitate the tightening or loosening of nuts in restricted spaces, the arcuate recess 5 being greater than a semi-circle to prevent the handle falling away directly when the pivot is removed. In a modification, a bent handle 17, Fig 8, is provided, which is reversibly connected to the head 2 by a bolt 18. The movable jaw member 6 is guided in the head 2 by means of interengaging ribs and recesses 13, 14 of square or curved section, or by pin-and-slot connection. In another modification the base of the recess 5, Fig. 15, has a convex projection 27 rolling on a concavity 26 in the end of the cam 4, and the jaws 29 are shaped at 28 for gripping pipes. The handle may have a pivoted extension 22, Fig. 9, connected by a ball-and-socket joint 20, 21.
