Abstract
A clutch-brake assembly adaptable for use in a lawn mower having a rotary blade. The assembly is fully enclosed by a housing (34) secured to the engine. Drive shaft (14) of the engine rotates the input member (20) via keys (22). A conical annular ring (74) has an annular surface (106) engageable with surface (110) of member (20) to rotate output member (28) and the attached blade (90). Self-energizing camming surfaces (80, 82) are employed to insure one-to-one drive between the input and output members. Springs (84) are used to bias ring (74) into engagement with member (20). An axially movable braking ring (54) with limited rotational movement relative to housing (34) is engageable with an annular surface (108) of ring (74). Movement of ring (54) is caused by springs (70) and ramping surfaces similar to those of (80, 82). The assembly employs the same oil used in the reservoir of the engine. Unique connecting means ( 36) are employed to reduce nonrotatable loads on shaft (14). Output shaft portion (88) is bushed in housing (34) in a manner to reduce nonrotating loads on shaft (14).
