  • Patent number: 4088072
    Abstract: A can crusher, particularly suited to reducing cans or similar containers to a compact form by crushing the containers between a pair of opposed jaws. The crusher consists of a track which serves as a base for the crusher and a trolley which is attached to and slides along the track. A first plate transversely attached to the track forms the lower jaw. A second plate is attached to the trolley in juxtaposition with the lower jaw to form an upper jaw. A lower pair of parallel lever arms are pivotally attached at their lower ends to opposite sides of the lower jaw. An upper pair of parallel lever arms are each pivotally attached at a midpoint to the opposite sides of the upper jaw and pivotally attached at their lower ends to the upper ends of the corresponding lower pair of lever arms. A handle is attached to the upper end of the upper pair of lever arms to serve as an operating grip.
