ABSTRACT:
A bi-directional, speed reducing mechanism for use with hand-held power tools comprises a pair of epicyclic gear trains mounted in a common carrier which each independently engage one of a pair of cages or ring gears disposed thereabout. The cages may alternately be locked in a stationary position or released for free rotation by independent activation of one of two identical wrap spring brakes disposed about each of the cages. The mechanism is contained within a generally cylindrical housing suitable for positioning between a conventional unidirectional power tool motor and gear head or powered device. In addition to the reversing capability, speed reduction in the range from 3.5:1 to 9:1 is also achieved by this mechanism.
