  • Patent number: 6701832
    Abstract: The present invention contemplates a trash can that one finds in high-traffic public venues. The trash can receives trash through an opening in the top of the housing. A trash by-pass chute is disposed within the housing and transports the trash from the opening in the top to the lower portion of the housing. A mechanism for automatically compacting the trash in the lower portion of the housing is provided within the housing. The compacted trash may be removed from the lower portion of the housing via a door that opens to allow access through the side of the trash can. The mechanism for compacting trash contents includes a frame disposed within the housing, and a compacting mechanism carried by the frame. The compacting mechanism includes a platen and is configured for moving the platen through a compaction stroke to apply compacting pressure to trash contents located in the lower portion of the housing during at least a portion of a compaction stroke.

  • Patent number: 6553903
    Abstract: An hydraulic press includes a head member removably connected at each opposite end to a leg and formed of a unitary sheet of steel rolled into a generally U-shaped transverse cross-section. The head member includes a reinforcing tube at its mid portion. The press includes a bed supported by the legs and disposed beneath the head member. The bed is reinforced at its mid portion by a pair of diagonally disposed spacer plates in the interior of the bed and at the exterior of the bed by a breast plate permanently attached to the front panel and a back plate permanently attached to the rear panel of the bed. At least one additional hole is provided and bored transversely through each end of the bed and positioned so as to correspond to and align with the holes in each leg that receive the pins that support the bed. The pressing force can be provided by an hydraulic jack that can be attached to the head member or to a carriage that is slidably disposed between the head member and the bed.
