ABSTRACT:
A differential clutch comprises a driving member having a plurality of inner circumferentially disposed clutch teeth cooperating with a lesser number of sprags resiliently urged outwardly on an intermediate member. A second set of sprags on the intermediate member cooperates with clutch teeth on a fixed member to prevent retrograde movement. Rocking back and forth of the turnable member acts through the clutch teeth and sprags to turn the intermediate member. The intermediate member is connected to a driven member, for example, for adjusting a brake, or for acting as a part of a ratchet wrench.
