Abstract
A ratcheting driver for rotationally driving a piece and having a handle and pivotal pawls engageable with a driven gear and being capable of ratcheting and driving in both rotational directions. A cap is rotatable relative to said handle and it has a web for pivoting the pawls out of engagement with the gear. Through the selective rotation of the cap, the setting of the pawls is established. A spring positions the pawls in driving positions, and the cap has surfaces which disengage the pawls from the gear upon rotation of the cap. A method of arranging the driver is included.
