Abstract
A pair of clutch-brake units each include a housing confining a cooling oil and rotatably supporting an input shaft and an aligned output shaft with interfitting clutch plates and discs for connecting the aligned shafts and interfitting brake plates and discs for connecting the output shaft to the housing. Each housing also encloses an axially movable non-rotating actuating piston for selectively engaging the clutch and brake plates and discs, and the input shafts of the clutch-brake units are driven continuously by a common electric motor. The output shaft of one clutch-brake unit is connected by a first drive mechanism to raise and lower or reciprocate a vertical shaft supporting a head member which carries a transfer arm, and the output shaft of the other clutch-brake unit is connected by a second drive mechanism to oscillate the vertical shaft, head member and transfer arm.
