ABSTRACT:
A fluid operated clutch and brake assembly is adapted to be connected to a motor driven flywheel and a rotatable drive shaft for a press or the like. A fluid operated piston mounted on the flywheel simultaneously engages the clutch and disengages the brake. The brake is spring biased to automatically stop rotation of the shaft when the clutch is disengaged. A first portion of the assembly mounted for rotation with the flywheel includes a fluid cylinder, a piston and a pair of spring biased clutch plates which are axially displaceable by the piston. A second portion mounted for rotation on the drive shaft includes two spline plates and a brake plate and a double splined hub, the spline plates being axially slidable on the splines of the hub. The brake plate is normally biased into frictional engagement with a stationarily mounted brake. Actuation of the piston engages the clutch plates with the spline plates and disengages the brake plate.
