Abstract: A method and apparatus for cleaning surfaces using a high velocity stream or streams of cleaning fluid. The high velocity stream or streams issue from one or more nozzles that are moving at a high velocity relative to the surface to be cleaned and are directed at the surface at an inclined angle thereto. In one embodiment, the source of cleaning fluid is under a high pressure of about 200 to 700 pounds per square inch and the nozzles are moving in a direction so that the velocity imparted to the issuing stream by each moving nozzle adds to the already high velocity of the stream due to the high pressure alone of the source of cleaning fluid. In another embodiment, two nozzles are rotated at a high velocity about an axis perpendicular to the surface to be cleaned with each nozzle being directed at a different area of the surface and having a different flow rate, angle of inclination to the surface, spray pattern, and/or spraying arc.

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.

Abstract: An elongated cylindrical housing is arranged to be mounted adjacent to and parallel with the surface of a moving abrasive member and has a row of ports establishing communication between the interior of the housing and its exterior. An elongated cylindrical core member is rotatably supported in the housing and has a spiral groove in its surface of a selected width and pitch such that a small number of ports are exposed to the groove at a time to form a narrow jet. Fluid under pressure is supplied to the groove and upon rotation of the core member the jet of fluid travels across the surface of the moving abrasive member to clean it. A cam is provided in the present apparatus to reciprocate the housing in its longitudinal dimension through a distance approximately equal to the spacing of the ports so that the surface of the abrasive member between the ports is also cleaned.

Abstract: Absorption of treatment composition into a surface layer of particulate material in a moving bed is substantially increased by spraying a major portion of the composition through a first group of nozzles and a minor portion of the composition through a second group of nozzles, the nozzles being attached to the top of a common transverse spray header which is oscillated across the moving bed. The first group of nozzles directs a plurality of substantially parallel vertical jets onto the surface of the moving bed to form therein, on combined motion of the bed and spray header, a zigzag pattern of trenches. The treatment composition is retained in these trenches as it is absorbed by adjoining particulate material. Loss of treatment composition due to run-off over a sloping or insufficiently wetted surface is avoided.
