ABSTRACT:
A crusher for articles such as aluminum cans, having a crushing chamber with a bearing plate disposed in the base thereof. An ejection lever is disposed within the bottom of the crushing chamber and is utilized to actuate a crusher piston and eject the crushed article at the end of a cycle. In the embodiment disclosed, the placing of an article within the crushing chamber retracts the ejection lever against a spring or other mechanical bias element. This movement of the ejection lever then actuates a switch to operate the crusher piston. The downward operation of the crusher piston causes a latch to restrain the ejection lever in its retracted position. As the crusher piston reaches the maximum amount of travel, a limit switch reverses the drive mechanism and the crusher piston moves upward. When the crusher piston reaches its uppermost position it operates the latch restraining the ejection lever and the ejection lever is mechanically biased toward its original position, ejecting the contents of the crushing chamber and deactivating the crusher piston.
