<p>785,738. Centrifugal clutches. KUBICEK, J. Nov. 9, 1955, No. 32001/55. Class 80 (2). A centrifugal clutch comprises a split spring ring 7 with a friction facing 8 supported on a driving sleeve 1 for rotation therewith by projections 9 and adapted to engage frictionally on expansion with the internal surface of a driven pulley 11. A ring of segmental weights 3 are arranged in an annular groove 2 of the sleeve 1 and are adapted to be driven frictionally by an interfitting ring 6 to move outwards by centfifugal force against the spring ring 7. A spring 5 biases the weights 3 to the inner retracted position.</p> |
