Abstract

Abstract A trash compactor including a housing, a ram mounted for vertical movement in an upper rear portion of the housing, and an open top drawer slidable in the housing between a compacting position beneath the ram and non-compacting position wherein the open top of the drawer is not aligned with the ram. A compartment for initially receiving waste material, particularly smaller objects, is situated near the upper front of the housing in position to empty into the drawer when the latter is out of the compacting position.
