Abstract

1432152 Ratchet clutches SPERRY RAND CORP 20 March 1973 [29 March 1972] 13339/73 Heading F2C A double ratchet clutch mechanism for a tape recorder drive comprises a pair of pawls 48, (49) pivoted on a hub 46 and engaged by pins 56, (57) fast with a driving sleeve 44 so that relative rotation between the sleeve 44 and hub 46 engages the pawl 48 with a tooth 62 on a first driven disc 28 when the sleeve 44 is rotated in one direction and engages the pawl (49) with a tooth (63) on a second driven element 64 when the sleeve 44 is rotated in the opposite direction. Stops 54, (55) determine the clutch engaged positions of the pawls 48, (49). As shown in a tape recorder drive a reversible electric motor 16 drives the sleeve 44 through a belt reduction gear 17, 18, 20, 22, 24. The driven disc 28 is fast with a take up spindle (40) and the driven element 64 is connected by a belt gear 32 to a feed spindle 42.
