Abstract

1528941 Controlling winches THOMPSON BROS (ENGS) Ltd 24 May 1976 [19 Sept 1975] 38594/75 Heading B8B [Also in Division F2] A winch includes a drum driven from the output shaft 11 of an internal combustion engine through a drive train including a reduction gear-box 25, an electromagnetic brake and an electromagnetic clutch, an electrical emergency stop switch being provided to free the clutch, apply the brake and stop the engine by cutting off the fuel supply. The clutch comprises a clutch disc 12 keyed to the shaft 11 and having friction pads 13 for engagement with a friction disc 18 which is spring biased towards and mounted for axial movement on, a rotatable coupling disc 16. The friction disc 18 is formed from magnetic material and upon energization of an electromagnetic coil 14 in a stationary housing 15, the disc 18 engages the pads 13 against spring bias for clutch engagement. The coupling disc 16 is flexibly coupled to another coupling disc 21 keyed to an input shaft 24 to the gear-box 25. The shaft 24 has a brake disc 26 splined thereto for rotation between brake friction pads 27, 28 carried by a station housing 29 and a movable member 30. The member 30 is slidably mounted on bolts 31 supporting a brake housing 32 carrying an electromagnetic coil 33 which is energizable to draw the brake member 30 away from the brake disc 26 against spring bias. The brake member 30 may be manually released by a lever 35. The electrical control circuit for the winch drive is arranged such that fuel is supplied and. the internal combustion engine is started upon depression of a starter button. The winch drum can then be started or stopped by appropriate depression of start or stop buttons which cause energization or de-energization of the coils 14 and 33 to either engage the clutch and release the brake, or engage the brake and release the clutch. An emergency stop button is provided which when depressed de-energizes the coils 14, 33 and cuts off the engine fuel. An alarm is sounded if the engine stops whilst the fuel supply is still open.
