Abstract
A construction for handling soiled tableware whereby the tableware is loaded on a cafeteria tray or the like and wherein the tray is moved to a station for discharging the tableware from the tray. A paddle or the like provides a lifting means which operates to pivot the tray to achieve a partial tilt thereof. A swinging arm serves as a second lifting means which engages the partially tilted tray and completes pivoting movement so that the contents of the tray will be completely removed by gravity. The driving action for both the paddle and swinging arm comprises a single rotating shaft supporting the paddle and carrying an eccentric which transmits swinging movement to the arm.
