Abstract

1368738 Winch drive LEWMAR MARINE Ltd and D J FAWCETT 10 Nov 1971 [11 Nov 1970] 53711/70 Heading B8B [Also in Division F2] A multi-speed manually operable winch comprises a drum 8 drivable either directly from a drive spindle 5 or through one of two reduc- tion gear trains, whereby the drum is rotated in the same direction with opposite directions of the drive spindle when the reduction gears are selected. A manually engageable unidirectional drive means 1, 6 between the spindle 5 and drum 8 permits either the direct drive in one rotational sense of the spindle, or one or other of the reduction gear drives depending on the rotational sense of the spindle, unidirectional devices in both reduction gear trains determining the ratio in response to the spindle sense. The reduction gear trains comprise an internal gear 16 on the drum 8 engageable by an idler gear 11 driven either by a pinion 10 coupled with the spindle 5 through a ratchet device 12, 13 or by an intermediate gear including a ratchet device and in mesh with a pinion 9 integral with the spindle 5. The reduction gear operable by rotation of the spindle in the same sense as the direct device, is over run when the direct device is selected. The normally operable unidirection means may comprise either pawls on the spindle and a ratchet on the drum or vice versa, the pawls being operated by means on the spindle or external thereto, or camming rollers between the spindle and drum.
