Abstract
Disclosed herein is a portable pipe wrench comprising a relatively stationary main frame including a rearwardly extending elongate handle and a forwardly disposed power train having a pair of roughened spurs for securely engaging and rotating a pipe segment and a nipple which is powerably actuatable by a suitable external torque-producing driver means. The portable pipe wrench also comprises a relatively movable jaw member slidably associated with the frame member and including a pair of idler wheels cooperating with the two spurs to rotatably manipulate the securely engaged pipe and further comprises a locking-adjusting assembly for the movable jaw relative to the main frame and the pipe. The main frame, the movable jaw, and the locking-adjusting assembly include several novel features which facilitate the task of securely engageably grasping and rotating the threaded pipe segment.
