Abstract: A parts washer and a method of washing parts. The parts washer has a cabinet having a rotatable turntable for carrying parts in a circular path and an oscillating spray manifold has spray nozzles directed toward the top, bottom and side of the parts and is caused to oscillate in an advancing movement counter to the direction of travel of the parts on the turntable and a return movement. The rate of travel of the spray nozzles varies in the two directions of movement with slower travel in the advancing movement and fast return movement to insure that successive sprays delivered by the spray nozzles in the advancing movement overlap on the parts to avoid any striping effect on the parts.

Abstract: A power parts washer having a cabinet with a washing chamber and a sump therebeneath and a liquid circulating system including a plurality of spray nozzles in said chamber. The liquid circulating system includes structure to circulate grit taken from parts being washed for improved cleaning action, with the structure including a coarse filter in the sump in advance of the intake section thereof whereby grit of a certain size may pass through the filter for intake into the circulating system. The spray nozzles have openings of a size and shape to permit flow therethrough of liquid and entrained grit which has passed through the filter.

Abstract: A power washer with a cabinet having liquid spray structure for cleaning of parts, such as automobile parts, and having a circular turntable within the cabinet for support of parts to be washed. The turntable is driven by a drive structure located exteriorly of the cabinet and having a drive wheel extended through an opening in a side wall of the cabinet to engage with a rim of the turntable to cause rotation thereof. The turntable is mounted for movement between an operating position within the cabinet and a part loading and unloading position outside the cabinet by movement through a front opening in the cabinet. A door is mounted on the movable support structure for the turntable whereby the door and turntable move together and a latch holds the door closed and causes the turntable to firmly engage said drive wheel.
