ABSTRACT:
A waste compacting apparatus includes a compactor housing with a vertically reciprocating ram mounted in its upper portion. A waste inlet is provided in the middle portion of the compactor housing for receiving waste, and the received waste is fed into a removable waste receptacle located in the lower portion of the compacting housing. Waste compaction takes place when the vertically reciprocating ram is driven down into the receptacle in the lower portion of the housing. The waste receptacle is horizontally slidable from a first position within the compactor housing, in which compacting takes place, to a second position outside the housing, during which the receptacle is unloaded. A vertically reciprocating sleeve is mounted within the housing, surrounding the ram, and has a waste inlet aperture in its upper portion. The sleeve extends downward from an upper position, in which the housing waste inlet is blocked by the sleeve, to a lower position, in which the waste inlet of the housing and the waste inlet aperture of the sleeve are aligned to permit waste to enter the sleeve and the lower portion of the sleeve extends into the lower portion of the housing within the removable waste receptacle. In this manner the sleeve protects the receptacle as the ram is extended downward to compact the waste within the receptacle. Both the ram and sleeve may be provided with slidably contacting shearing knives, so that any waste trapped between the ram and sleeve will be sheared off and will not jam the compaction apparatus.
