Abstract: A trash compactor includes a loading vestibule which extends forwardly of a cabinet. Pivotally mounted to a lower edge of the vestibule entrance is a carriage having a panel which functions as a vestibule lid. When the lid is pivoted downwardly, a distal panel of the carriage pivots upwardly, blocking access to a trash discharge outlet. Trash is then loaded on the carriage. When the lid is closed, the distal panel is sloped downwardly to an angle which discharges the trash through the discharge outlet and into a trash compaction compartment. An overhead compaction mechanism includes a reciprocating ram which compresses the trash in the compaction compartment.
