Abstract
Abstract Tilting means for trays carrying soiled tableware so that the tableware can be discharged for entry into a dishwashing machine while the trays are delivered to a separate washing machine. The tilting means comprises lifting elements on an endless conveyor which move into contact with one side edge of a tray. The opposite edge of the tray engages abutment means which provide a pivot location whereby the tray is tipped and the soiled tableware is removed. A separate conveyor then moves the trays away from the abutment means for delivery to the separate washing machine.
