Abstract
A clutch and brake apparatus (2) includes a drive member (8) and a driven member (14) axially fixed to drive member (8). An array (50) of friction discs (52 and 54) is axially movable in a clutch chamber (22) in driven member (14). Friction discs (52) continuously engage drive member (8). Springs (48) force array (50) into engagement with thrust surface (60) on driven member (14) to couple driven member (14) to drive member (8). The driving connection is broken by a movable shell (66) which engages against the lowermost friction disc (54) through pins (74) to selectively move array (50) downwardly against the force of the springs (48). Shell (66) is moved downwardly by fingers (86) which also engage against a brake pad (76) on shell (66) to stop rotation of driven member (14).
