ABSTRACT:
A machine for crushing oil filters and collecting the oil therefrom. The machine has a piston and cylinder assembly for moving a crushing member into a crushing chamber to crush an oil filter. A control valve controls the supply of hydraulic fluid to the piston and cylinder assembly. Air under pressure is also supplied to the piston and cylinder assembly to move the crushing member back to its initial position. A lock is mounted on the actuator of the control valve for holding a door providing access to the crushing chamber in the closed position. When the actuator is moved to a position to allow fluid to flow to the cylinder the door is locked in the closed position. A second lock structure maintains the door in the closed position during the time that the crushing member is performing the crushing operation. The crushing member must be moved to its initial position to release the second lock structure before the door can be opened.
