ABSTRACT:
A tray container for liquid chemical compositions such as those used in developing photographs or pictures, is pivotally carried on a support for tilting or rocking movement. A spring biased support means is disposed under one end of the tray and a motor driven movable cam is located under the other end. The tray is tilted at one end when engaged by the cam surface and the other end thereupon compresses the spring. When the cam surface becomes disengaged from the tray, the spring is relieved and returns the other end of the tray to its initial position with a jar or snap action, thereby agitating the liquid chemical in the tray.
