ABSTRACT:
An improved clutch assembly includes a rotatable driving clutch part having leading and trailing lug portions thereon and a coaxially rotatable driven clutch part. First and second adjacently-positioned pawl elements are mounted on the driven part for opposing pivotal movements between respective retracted and extended positions, being urged by respective springs to their respective extended positions. In their respective extended positions, the first pawl element is disposed for driving engagement with the leading lug portion while the second pawl element is disposed for engagement with the trailing lug portion so as to prevent any substantial amount of overrun of the driven clutch part relative to the driving clutch part. In their respective retracted positions, the first and second pawl elements are withdrawn from engagement with their respective lug portions. Interengageable means in the form of a pair of opposing ledges formed respectively on adjacent portions of the pawl elements insure that the second pawl element will pivot to its retracted position when the first pawl element is moved to its retracted position.
