摘要： An apparatus for driving and braking a cutting blade of a lawn mower is disclosed. The apparatus includes a shaft extending through a housing for rotating the blade, and an engine-driven pulley. The apparatus includes means for biasing the pulley toward the housing, and means for translating the pulley away from the housing. The apparatus has a stopped position in which the pulley and housing are in friction contact, and a cutting position in which the pulley and housing are not in friction contact. When the engine delivers power to the pulley, the apparatus moves from the stopped position to the cutting position such that the pulley and the housing are not in friction contact and the blade rotates. When power delivery to the pulley ceases, the apparatus moves from the cutting position to the stopped position, placing the pulley and housing in friction contact, and the blade stops.

摘要： A deadman brake (62) is provided for stopping a rotating member driven by a power source, including the flywheel (46) of an internal combustion engine (42) of a lawnmower (40). A cantilever leaf spring (94) has a root end (96) attached to an engine-mounted bracket (68), and a distal end (98) movable toward and away from the flywheel (46). A brake pad (100) is attached to the cantilever leaf spring (94) and normally engages the flywheel (46) under self-bias of the cantilever leaf spring (94). A cable system (56, 58) is coupled by a transfer member (72, 134) to the cantilever leaf spring (94) and is actuated to disengage the brake pad (100) from the flywheel (46). The transfer member (72, 134) is a double pivot (106, 126) member providing universal right hand and left hand direction actuation application.

摘要： A drive mechanism (20, 120) includes a driving rotary member (22, 122), a driven rotary member (24, 124), and a clutch (26, 126) operatively coupled between the driving member and the driven member and responsive to rotation of the driving member to automatically engage and rotate the driven member after a given amount of rotation of the driving member. The clutch is self-actuated in response to rotation of the driving member. A brake (36, 136) has a braking condition stopping rotation of the driven member, and a released condition permitting rotation of the driven member. Axial movement of the clutch face (34, 134) from its released position to its driving position also actuates the brake from its braking condition to its released condition. The drive is bidirectional, and is particularly useful in a nutational washing machine.
