ABSTRACT:
A driver for socket wrenches or similar tools constructed to effect rotation of the wrench by rotary wrist action. Manual rotation of a grip is transmitted through shafts and gears to the tool lug and a ratchet mechanism is provided to permit the selective transmission of torque to the tool in either direction of grip rotation. The mechanism is lockable to override the lost motion ratcheting action when desired. A tool receiving recess in the grip permits the application of increased torque when required to rotate the tool lug.
