Abstract
A reversible speed reducing mechanism for use with hand-held power tools comprises a pair of juxtaposed epicyclic gear trains mounted in a common carrier which independently engage a pair of cages or ring gears. The cages may alternately be locked to or released from an outer housing to accomplish the bidirectional transmission of rotational power. The complete reversing mechanism is housed in a generally cylindrical body suitable for mounting between a conventional unidirectional motor and gear head or powered device. Forward or reverse output rotation is selected by moving a control button positioned on the periphery of the reversing mechanism. Speed reduction in the range from 3 to 5 to 1 can be achieved by this mechanism.
