ABSTRACT:
A ratcheting driver handle has a ratchet body press-fitted axially in one end thereof, the body defining a socket which receives a gear for rotation coaxially with the handle. The socket also receives two pawls respectively disposed above and at opposite sides of the axis and spring-biased into engagement with the gear. A selector cap rotates on the housing and carries a first pin for driving the pawls respectively out of engagement with the gear, depending upon the direction of rotation, to control the ratchet direction. A second pin on the cap engages an over-center leaf spring mounted in the socket below the gear for resiliently retaining the mechanism in either of the forward or reverse conditions. A driver bit has a flattened end which is received through an axial bore in the cap and into a complementarily shaped bore through the gear for rotation therewith, being frictionally retained in place by a retaining ring.
