Patent number: 4408625Abstract: An article washing device is disclosed which includes movable spray heads for both washing and rinsing while the article is stationary or moving. The housing is defined with the washing compartment therein having a frame means suspended from the upper portion thereof. The frame means is powered to move to and fro within the washing compartment. A supply line for washing solution and a supply line for rinsing solution are secured to the frame means and are oriented peripherally about the washing compartment. Spray heads are located in each of the washing and rinsing solutions such that the washing or rinsing solution can be released from the respective conduit while the frame means and the conduits themselves are moving back and forth longitudinally within the washing station. In this manner complete washing and rinsing of an article having many difficult areas to clean such as a rack is achievable.Type: GrantFiled: May 7, 1982Date of Patent: October 11, 1983Inventor: Henry Y. Kuhl

Patent number: 4266565Abstract: An upper spray arm is mounted to the underside of the upper dish rack of a dishwasher and rotates in response to a jet of water supplied through the lower spray arm. The upper spray arm mounting is provided with a self-aligning bearing which includes a stationary mounting platform attached to the upper dish rack and a flanged, cylindrical bearing connected to the spray arm. An enlarged bore in the mounting platform accommodates the bearing cylinder and permits radial movement of the bearing cylinder relative to the platform. The bearing flange transmits thrust forces to the stationary platform and slides radially relative to the platform to the extent the platform bore is larger than the bearing cylinder. Impetus for radial movement of the bearing and spray arm is produced by a bell shaped receiver located on the underside of the spray arm.Type: GrantFiled: October 12, 1979Date of Patent: May 12, 1981Assignee: Whirpool CorporationInventor: Vincent P. Gurubatham

Patent number: 4178652Abstract: A method and apparatus for automatically cleaning the surface of a roller, such as a laminating roller, is disclosed herein. The method consists of rotating the roller at a predetermined fixed speed about its axis and simultaneously moving a nozzle which produces a small stream of steam along the axis of the roller at a fixed speed so that the stream of steam impinges the entire surface of the roller. The apparatus consists of a support for rotatably supporting a roller and supporting a nozzle for reciprocation with respect to the axis of the roller with either common or separate drive means for rotating the roller and reciprocating the nozzle.Type: GrantFiled: April 24, 1978Date of Patent: December 18, 1979Assignee: Arvey CorporationInventors: Leo Adams, Edward Kooi

Patent number: 4170240Abstract: 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.Type: GrantFiled: November 1, 1977Date of Patent: October 9, 1979Inventor: Richard W. Gentry

Patent number: 4150512Abstract: 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.Type: GrantFiled: August 29, 1977Date of Patent: April 24, 1979Inventor: Walter M. Novak
