Abstract
435,148. Clutches. McKENZIE, S. B., 47, Grosvenor Street, Toronto, Canada. June 13, 1934, No. 17554. [Class 80 (ii)] A clutch device comprises oppositelyacting sets of caged wedging rollers l, s, one set l being arranged between cam pockets on a boss c, which is carried on the driving shaft a by a quick - pitch thread i<1>, and the cylindrical inner surface of a flange e on the driven shaft f, and the other set s being arranged between the cylindrical inner surface of a flange d secured to the shaft a and cam pockets on the outer surface of the flange e. A disc w, which is slidable on the shaft f and is connected for rotation with the cage t of the outer set of rollers s by pins y, carries conical projections z adapted to co-operate with conical recesses a<1> in the flange e. With the disc w in the normal position shown in Fig. 1, in which it is held by spring-pressed ball detents g<1>, bidirectional drive is transmitted. If the disc w is moved to the left, by a control lever d<1> through a collar c<1>, the projections z co-operate with the recesses a<1> to turn the cage t so as to render the rollers s inoperative, and the shaft f can now overrun. During overrunning, the boss c moves to the left due to the thread i<1>. The disc w is maintained in its left-hand position by a spring f<1> until the shaft a again takes up the drive, whereupon the boss c screws back to its right-hand position and in so doing moves back the disc w, through pins l<1> slidable in the flange e, to its normal position, restoring bidirectional drive. In a modification, the outer cage t is adapted to be turned through the medium of bell-crank levers pivoted on the flange e and actuated by a conical-ended collar slidable on the shaft f.
