ABSTRACT:
A reversible ratcheting driver handle has an axial cavity in one end receiving an insert which defines an axial compartment for receiving a ratchet mechanism including a rotatable gear and two pawls seated in recesses in the insert and for reciprocating movement along parallel paths between engaged and disengaged conditions relative to the gear, being spring-biased to the engaged conditions. A selector cap telescopes with the one end of the handle and has a recess non-rotatably receiving a control member which has a part-cylindrical actuator wall which fits part way around the gear and has opposite end engageable with the pawls for shifting them to their disengaged conditions in response to rotation of the cap. Roll pins secure the cap, the insert and the handle together while limiting rotational movement to the cap.
