Abstract

436,284. Free-wheel clutches. COLLYEAR, J. R., Leverno, Bleecheroft Road, Bushey, and BAXENDEN, T. G., Lawrenny, Hempstead Road, Watford, both in Hertfordshire. Feb. 9, 1934, No. 34721/33. [Class 80 (ii)] Forward drive is transmitted from a driving shaft 1, Fig. 1, to a driven shaft 2 by a number of inter-wound helical springs 3 which frictionally engage both shafts, or which frictionally engage the shaft 2 and are secured to the shaft 1. The end 4 of each spring engages a slot 5 in a surrounding sleeve 6 which is itself encircled by a helical spring 7, the end 8 of which is secured to a fixed member 9, whereby, on reverse rotation of the shaft 2, the spring 7 tightens on the sleeve 6 so as to prevent the transmission of such reverse rotation to the shaft 1. Alternatively, the sleeve 6 may have ratchet teeth co-operating with a detent pawl. The springs 3 may grip the shaft or shafts through the intermediary of a split friction sleeve or sleeves. As shown in Fig. 3, the springs 3 engage recesses in the members 1 and 2, the sleeve 6 being replaced by a shaft 14. A flywheel may be fitted as in Specification 420,306. Specification 386,358 is referred to in the Provisional Specification.
