A press drive mechanism is disclosed having relatively rotatable output shaft and flywheel components which are independently rotatably supported at their opposite ends by fixed support members. The flywheel is mounted on a sleeve which is concentric with the output shaft and located between the opposite ends of the shaft. Clutch discs are cooperatively supported by the sleeve and output shaft, and brake discs are cooperatively supported by the output shaft and one of the fixed support members. The brake and clutch are alternately engaged and disengaged by means of a pneumatic piston and cylinder assembly concentric with the output shaft inwardly adjacent the other of the fixed support members. |
