A clutch device comprises a continuously rotating toothed drive wheel 18 which can be coupled to a disc 20 secured to the driven shaft 12 by means of primary and secondary clutch members 22, 24, of which the secondary member 24 is arranged to be effective at least during the period of disengagement of the primary member 22. The clutch members are in the form of pawls 22, 24 carrying single teeth 32, 40 engageable with wheel 18, member 22 having an end pivot 26 and member 24 an intermediate pivot 34, the ends of the pawls being connected by a spring 46 whereby teeth 32, 40 are normally biased into and out of engagement with wheel 18 respectively. The end of pawl 22 adjacent its pivot 26 has a projection 54 engageable with a shoulder 52 on a trip member 48 loaded by a spring 56 which may be overridden by a magnet armature 48a, the trip being actuated during each revolution of disc 20 by a striker arm 60 projecting from the disc. For continuous rotation of disc 20 electric pulses are fed at appropriate intervals to a demagnetizing coil 66 whereby shoulder 52 of trip 48 is held clear of pawl projection 54 by spring 56. The nose portion of pawl 24 is so shaped that during each revolution it contacts a cam 70 for intermittent engagement of tooth 40 with wheel 18 while projections 52, 54 are in close proximity, so that if the mechanism is conditioned for continuous drive secondary pawl tooth 40 periodically reinforces the main drive, but if trip 48 is positioned to break the drive tooth 40 maintains a positive engagement with wheel 18 during the interval in which tooth 32 on primary pawl 22 is disengaging from the wheel, after which spring 46 operates to release tooth 40 and thus completely break the drive. Under such conditions the engagement of a recess 25 in pawl 24 by the nose of cam 70 supplements the engagement of projections 52, 52 to hold disc 20 ocked.
