Abstract

1377921 Ratchet clutches SIEMENS AG 5 March 1973 [24 March 1972] 10505/73 Heading F2C In a one-way clutch for a telephone impulse generator wherein balls 2... 4 wedge between cam surfaces on a plate 13 and a cylindrical surface 5 on a driven or driving gear 1, the balls 2 are positioned by axial projections 7, 8 ; 9, 10; 11, 12 on a guide plate 6. As shown, the cam plate 13 is fast with a driving or driven shaft 22 whilst the guide plate 6 is urged into frictional contact with the gear 1 so that on relative rotation between the cam plate 13 and gear 1 the projections 7, 8; 9, 10; 11, 12 on the guide plate 6 carry the balls 2 ... 4 into or out of wedging engagement. Alternatively the guide plate 6 may be connected to the driving or driven shaft whilst the cam plate 13 is urged into frictional engagement with the gear 1. The gear 1 and guide plate 6 may be made of plastics material, the gear having a cylindrical race 5 secured thereto.
