  • Patent number: 4100850
    Abstract: A trash compactor has a rotatable lead screw and stationary nut for raising and lowering the compacting ram by rotation of the screw. A housing surrounds the nut for preventing rotation of the nut with respect to the screw while permitting limited pivotal movement of the nut with respect to the housing responsive to eccentric compaction forces applied to the compacting ram. The housing is distortable for the same reason and to permit absorption of shocks arising from compaction. The nut may be formed of a self-lubricating plastic. The drive mechanism may be used in a trash compactor having an extensible linkage of the scissors jack or lazy tongs type in which the lead screw is journalled in one of the intermediate junction points of the linkage. The housing containing the nut is located at the other of the junction points so that rotation of the screw extends and retracts the linkage.

  • Patent number: 4064798
    Abstract: An improved receptacle for a trash compactor is mounted on a drawer for movement into and out of the compactor along rails on the drawer. The receptacle is spaced from the rails so that dents or deformations of the receptacle do not affect the rails. The rear end wall of the compactor may be slanted so as to accommodate the arcuate travel of the ram of the compacting mechanism and the receptacle has a pyramidal shape to facilitate removal of the compacted trash.
