Abstract

1,188,405. Clutches. SPERRY RAND Ltd. 20 May, 1968 [8 June, 1967], No. 28487/67. Heading F2C. A clutch comprises a drive-transmitting synthetic plastics coiled spring member 15, Fig. 2, having one end connected to a rotary member 20 with which it rotates freely until the rotary member is braked whereby the spring is resiliently deformed to engage frictionally another drive transmitting member 14 and transmit drive thereto. When solenoid 21 is automatically or manually energized an armature 20, faced with a P.T.F.E. coating, is attracted towards the coil and thereby braked. The inner surface of spring 15, e.g. of nylon grips drum 14, e.g. of nylon or aluminium. The drive is transmitted from a gear 16, which may be integral with the spring 15, through spring 15 and drum 14 to the output shaft 12. Two clutches are arranged with their output members geared together to a common output so that when one clutch is operative the output is in one rotational direction and the output is in the other rotational direction when the other clutch is operative. The output shaft may be arranged to drive a control surface, e.g. a rudder or fin, in the sense to correct the orror and the signal from a potentiometer 29 used as a feedback to set against the error. Three pairs of clutches may be used so that each pair controls one of three sets of control surfaces.
