APPARATUS FOR DEVELOPING VARIABLE TORQUE

摘要

An apparatus for developing variable rotational drive torque which comprises an elongated handle adapted for rotation about a first axis, first drive means attached to the handle for rotation therewith and for directly developing drive torque about the first axis, means to disengage the first drive means from the handle and for permitting the handle to rotate about a second axis of rotation located between the first axis and the location of force application to the handle. Drive engagement means extends through the handle adjacent the second axis of rotation and is arranged and positioned for rotational engagement with at least a part of the first drive means when the handle is rotated about the second axis so as to transmit torque to the first drive means about the first axis of rotation. Means is provided to selectively vary the relative position of a portion of the drive engagement means in relation to the second axis of rotation to vary the torque transmitted to the first drive means and thereby developed about the first axis of rotation by the first drive means when the handle is rotated about the second axis of rotation.
