ABSTRACT:
A sliding jaw pipe wrench has a jaw adjustment mechanism comprising a longitudinally extending series of transverse recesses formed in one surface of an elongate shank on which the movable jaw of the wrench is formed. The shank is received in a retaining pocket in the wrench handle on which the stationary jaw is formed, and the handle includes a transverse locking pin for engagement in, and disengagement from the respective recesses to retain the movable jaw in position when engaged in a recess and allow the shank to be moved to adjust the jaws when disengaged from the recesses. The locking pin is operated by a trigger-like lever pivoted on the handle and connected to the locking pin by an elongate actuating rod. A spring engaging the lever urges the locking pin into engagement with the respective recesses.
