Abstract
A multiclutch drive having an input connected in series by a centrifugally engaged clutch, an intermediate drive and a spring engaged manually disengaged friction clutch to drive the output and a one way clutch between the intermediate drive and input which is engaged when the intermediate drive speed exceeds the input speed. Manual disengagement of the friction clutch provides positive neutral. For normal drive, manual engagement permits the spring engagement of the friction clutch and manually increasing engine throttle and engine speed engages the centrifugal clutch for normal vehicle drive. For a push start the friction clutch is manually disengaged while bringing the vehicle up to starting speed and then engaged to drive the intermediate drive to engage the one way clutch to drive the input for engine starting. The clutches are structurally arranged with the centrifugal clutch hub and the inner race of the one way clutch fixed to the input shaft. The centrifugal clutch shoes are pivoted on the hub and engage the ring portion of a centrifugal inner clutch drum having a disk backing plate portion fixed to the outer race of the one way clutch. An outer drum has a ring portion mov…
