Abstract

A cabinet has an upper portion which encloses a ram member movable vertically by a motor driven scissor-type actuator from an upper retracted position to a lower extended compacting position within a container positioned within the lower portion of the cabinet. The container is molded of a plastics material and is supported by a two-wheeled cart including pivotal arms which extend around an intermediate portion of the container and are locked together for restraining the container during compacting. When the container is tilted by the cart into a compacting position under the ram member, the container actuates a sealing frame which lowers and engages the upper rim of the container for confining within the upper portion of the cabinet any odors released by the material being compacted within the container.

Dependent claims

In a vertical compactor adapted for compressing batches of refuse or other waste material and including a frame, a generally horizontal ram member, actuator means mounted on said frame and supporting said ram member for generally vertical movement, an open top container positioned at a compacting station within said frame below said ram member and adapted to receive the material, power operated means for moving said actuator means to move said ram member between a retracted upper position and an extended lower position within said container for compressing the material within said container, and a wheel supported cart including a base member supporting the bottom wall of said container and providing for moving said container into and out of said compacting station, the improvement wherein said container comprises an open top container of molded plastics material and having an intermediate wall portion between said open top and said bottom wall, said cart including restraining means above said base member and extending in a confining position around said intermediate wall portion of said container for maintaining substantially the shape of said molded plastic container during compacting, and said restraining means being movable between said confining position and a released position to provide for conveniently removing said container laterally from said cart.

In a vertical compactor adapted for compressing batches of refuse or other waste material and including a cabinet having an upper chamber and a lower chamber, a generally horizontal ram member disposed within said upper chamber, actuator means supporting said ram member for generally vertical movement, a container positioned within said lower chamber below said ram member and having an upper rim portion defining a top opening for receiving the material, power operated means for moving said actuator means to move said ram member between a retracted upper position and an extended lower position within said container for compressing the material within said container, and a wheel supported cart supporting said container and providing for moving said container into and out of said lower chamber, the improvement comprising an odor confining member, means supporting said odor confining member for movement between a lower sealing position engaging said rim portion of said container and a retracted upper position providing for removing said container with said cart, means for moving said odor confining member between said sealing and retracted positions, and said odor confining member forming a seal between said container and said cabinet when said member is in said sealing position for confining any odors within said container and said upper chamber.

In a vertical compactor adapted for compressing batches of refuse or other waste material and including a cabinet defining an upper chamber and a lower chamber, a ram member disposed within said upper chamber, actuator means supporting said ram member for generally vertical movement, a container positioned within said lower chamber below said ram member and having an upper rim portion defining a top opening for receiving the material, power operated means for moving said actuator means to move said ram member between a retracted upper position and an extended lower position within said container for compressing the material within said container, and a wheel supported cart supporting said container and providing for moving said container into and out of said lower chamber, the improvement comprising an odor confining member, means supporting said odor confining member for movement between a lower sealing position engaging said rim portion of said container and a retracted upper position providing for removing said container with said cart, means for moving said odor confining member between said retracted position and said sealing position forming a seal between said container and said cabinet to confine any odors within said container and said upper chamber, said cart including restraining means extending in a confining position around an intermedite portion of said container for maintaining substantially the shape of said container during compacting, and said restraining means being movable between said confining position and a released position providing for conveniently removing said container laterally from said cart.
