Abstract
Abstract This invention is a trash compactor for compressing trash as it is moved in a horizontal direction, the compactor including a rectilinear section into which the trash is placed, a power member for forcing the trash through the rectilinear section and a curvilinear section into which the trash is forced for further compression. The curvilinear section is of sinuous or S-shape configuration and is disposed in either a vertical or horizontal plane. Engagement of the trash with the walls of the curvilinear section effect compaction of the trash prior to emission for disposal. A gate within the curvilinear section is operative to increase compaction therein before emission from the compactor.
