Abstract
A machine for cleaning heavy vehicle parts and the like in maintenance shops by spraying them with a detergent fluid or solvent. A parts tray with wheels may be rolled on tracks in and out of a heavy cabinet. The cabinet has a power-actuated door. Inside a cleaning chamber the parts tray is surrounded by a cage-like spray assembly of pipe equipped with spray nozzles directed inward at the parts. The spray assembly is mounted on a swinging parallel linkage, and is reciprocated back and forth by a motor. Below the spray or cleaning chamber is a tank or sump with an internal heater, which is normally full of fluid. A pump circulates heated fluid from this tank up to the spray nozzles; the fluid then runs back down into the sump for recirculation. A clean-out trap is provided for cleaning the sump. The operator's controls, including the door actuator control, are all located at the side of the machine for safety. An interlock switch prevents the pump from being started when the door is open.
