ABSTRACT:
A tool for transferring torque from a driving member to a workpiece comprises a plurality of serially engaging gears wherein a first gear of said plurality includes means for mating engagement with the driving member for rotation of the first gear thereby and a last gear of the plurality includes means for engaging the workpiece for rotation thereof by the last gear. The gears are rotatably mounted in a support frame. The last gear may include an arcuate segment hingedly connected to the remainder of the last gear and rotatable about the hinge connection between open and closed positions. The arcuate segment in the closed position completes a circular periphery of the last gear and in the open position provides a passageway for movement of the workpiece into the last gear interior.
