US Patent:

Filed:
Apr 22, 1991
Appl. No.:
7/688812
Inventors:

Abstract:
The disclosure describes a ratchet type of tool drive that has three partitions extending from the walls of a cavity to define channels with a spindle. The walls are thinner at a midpoint of each channel and are thicker adjacent each partition by a limited amount, such as 30 thousandths of an inch. A roller is located within each of the channels with a coil spring on each side. A retainer cover has extensions between each partition and one end of each coil spring, so that turning the cover one way or the other, applies a biasing pressure on each roller to urge the rollers in a desired direction. The structure described has fewer parts, is thinner in configuration and the rollers move in a slight rolling movement to be pinched between the narrowing walls of each channel, to achieve a positive locking and non-slipping action.
