ABSTRACT:
An elongated handle is provided defining a hand grip at one end and an enlarged head at the other end. The enlarged head has a reversible ratchet-type drive assembly supported therefrom including a rotary output shaft disposed transverse to the handle. The handle is tubular intermediate the handle and head ends thereof and rotatably receives a torque input shaft extending therethrough. The torque input shaft and output shaft include meshed gear wheels and the end of the input shaft adjacent the hand grip includes first torque transfer structure. An elongated head is positioned adjacent and disposed transverse to the hand grip in alignment therewith and includes laterally projecting second torque transverse structure releasably coupled with the first torque transverse structure. The elongated head, on the side thereof remote from the head end of the handle, defines an elongated laterally opening groove formed therein and an elongated crank arm has one end pivotally mounted in one end of the groove for swinging of the crank arm between a retracted position within the groove and an extended position projecting endwise outwardly of the aforementioned one end of the groove. The other end of the crank arm includes a right angulated terminal end portion generally paralleling the handle when the crank arm is in both the retracted and extended positions.
