ABSTRACT:
A safety device for limiting axial operating loads which are exerted on a drive worm of a machine, such as a platen press, including a pressure chamber receiving a first piston connected to an auxiliary shaft, which is axially shiftable and non-rotatable, and is connected to one end of a main shaft of the drive worm. Fluid pressure in the pressure chamber holds the piston in a first position to maintain the axially displaceable connection of the other end of the main shaft to a drive shaft. In response to an axial overload, the pressure in the pressure chamber is relieved to eliminate the holding feature to allow the main shaft to shift axially to disengage it from the drive shaft. The safety device includes a second piston for moving the first piston to the first position where the drive shaft and main shaft are recoupled when the machine is in a rest position.
