ABSTRACT:
An automatic clutch comprises, on the driving side, a drive clutch movable only axially relative to the associated drive members and normally biased in the declutching direction, a stationary inner cam located on the side toward which the drive clutch is biased and moved, the inner cam being connected to or disconnected from the drive clutch accordingly as the clutch disengages or engages, and a holdout ring having projections to be engaged with lands of the inner cam and adapted to keep the drive clutch and the inner cam out of connection when the driving side stops, the holdout ring being fitted over the drive clutch under such frictional conditions that, only when the ring has engaged the inner cam, it can circumferentially slide relative to the drive clutch. The automatic clutch further comprises, on the driven side, a driven clutch movable only axially relative to the associated driven members and normally biased in the clutching direction.
