Abstract
173,720. Defordt, J. F. Feb. 2, 1921. Clutches, free-wheel.-In free-wheel clutches or ratchet gearing comprising two concentric wheelmembers positively driven by radially-moving pawl-teeth, these teeth are positively reciprocated in both directions during backward movement of the outer member relatively to the inner member. The annular member 1 carries a plurality of sliding pawl-teeth 6 adapted to engage ratchet-teeth 5 on the inner wheel 2, in rigid relationship with which is a pair of rings 3 flanking the member 1 and provided with triangular projections 4 corresponding in number to the teeth 5. The projections 4 engage lugs 7 on each end of the pawlteeth 6 during free-wheel running and positively move them into position to engage the teeth 5. Pairs of spring-pressed balls 11 lodged in circumferential channels in the member 1 engage the semicylindrical or hemispherical ends 17 of the teeth 6 to prevent rattling and to retain them in the engaging-position against the action of centrifugal force or gravity. To reduce lost motion, the teeth 5, 6 are made different in number. In the example shown, there are four more pawlteeth than ratchet-teeth, whereby a diametrically opposite pair of teeth engage simultaneously.
