Abstract: An apparatus for neutralizing and disposing of infectious solid waste and non-hazardous solid waste includes a housing having an upper chamber for receiving the infectious solid waste and a lower chamber for receiving the non-hazardous solid waste. The upper chamber includes an exterior loading door, and an interior discharge door. A discharge ram forms one wall of the upper chamber opposite to the discharge door. The upper chamber includes door seals and pressure fittings so that the infectious waste placed therein may be sterilized by steam introduced under pressure. The neutralized wastes are ejected by the discharge ram through the interior door into the lower chamber. One wall of the lower chamber comprises a compactor ram which is extendable through a discharge opening to compress the neutralized and non-hazardous wastes into a closed compactor container.

Abstract: A train of tandem arranged, wheeled, refuse receptacles, pulled by a prime mover along a path, are successively moved over a dump chute to drop their contents when their discharge doors are successively tripped, the contents falling downwardly through the chute and into the entrance opening of an underground compactor. The reciprocating ram of the compactor passes the contents sidewise into the awaiting container of a refuse collection vehicle, compacting the contents therein.

Abstract: The Specification concerns a refuse disposal system in which a refuse compacting unit located adjacent a wall of a building has a refuse input accessible from inside the building and a refuse output accessible from outside the building for discharging compacted refuse into a removable container.In order to permit a high degree of freedom in the placement of the container the unit is mounted on wheels for mobility and is located in an aperture in the wall, the aperture being substantially wider than the unit. The unit is disposed between a pair of sliding doors mounted for movement parallel to the wall, the doors being coupled to opposite sides of the unit by upwarding directed rollers on the doors engaging inverted channels along opposite sides of the unit.

Abstract: A high volume refuse compacting apparatus utilizes a commercial horizontal axis ram compactor as a base and upon this unit are mounted in tandem relationship a relatively stationary hopper bin and a coacting power-operated pivotal dumping bin which is elevated to a steep angle to feed the hopper bin with refuse by gravity action. A bottom opening of the hopper bin is in registry with a provided opening in the compactor unit above the ram thereof. Corresponding side walls of the hopper and dumping bins are made shallow to facilitate side loading of the apparatus. A scissoring action of the side walls of the hopper and dumping bins substantially eliminates refuse spillage.

Abstract: An apparatus for tightly compacting material within a wheeled, open top container including a frame composed of a stationary base and a overhead section disposed above the container and coupled to the frame base section by a plurality of telescoping columns which permit the overhead section to raise and lower relative to the container. A plurality of nominally relaxed tension lines extend downwardly from the frame overhead section to interconnect with the upper rim portion of the container. The apparatus also includes a pressing head suspended below the frame overhead section by a pair of spaced apart hydraulic cylinders which are retractable to lift the pressing head to an elevation above the container or extendible to force the pressing head downwardly into the container. As the pressing head pushes against the material within the container, a reaction force is generated which initially causes the frame overhead section to lift upwardly until the tension lines are drawn taut.

Abstract: As a part of the combination there is provided a trash container of the type which can be picked up and dumped by inverting it by the lift usually found on the front or rear end of a trash collection vehicle. However, because the invention contemplates compaction of the trash in the container before its contents are dumped into the vehicle, the container has flared end walls, such as to permit the compacted contents to fall freely from the container upon its inversion by the vehicle lift. To accomplish the desired in-container compaction, a vertical hydraulically driven ram is mounted in such a way that the container may be placed below it when the ram platen is raised to its first and upper position.

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.

Abstract: A waste compacting apparatus includes a compactor housing with a vertically reciprocating ram mounted in its upper portion. A waste inlet is provided in the middle portion of the compactor housing for receiving waste, and the received waste is fed into a removable waste receptacle located in the lower portion of the compacting housing. Waste compaction takes place when the vertically reciprocating ram is driven down into the receptacle in the lower portion of the housing.

A vertically reciprocating sleeve is mounted within the housing, surrounding the ram, and has a waste inlet aperture in its upper portion.

Abstract: A trash compactor using a dolly as a receptacle for the trash to be compacted. The dolly is normally spring supported ready for movement into and out of the compactor, but when in the compactor and subjected to compacting pressure, the dolly is pressed downwardly, upon the beams of the main compactor frame which then takes the full compacting pressures.A novel construction of the dolly and compactor floor of the main frame makes such transfer of load possible. The compacting pressure is developed by four hydraulic cylinders, all of which are mounted on a common plate. The rod ends of the two center cylinders are connected to the top member of the main frame and the cylinder ends are connected to the common plate. The rod ends of the remaining two cylinders are connected to the main compacting plate with the cylinder ends mounted on the common plate. With the four cylinders mounted in this manner, twice the movement of the compacting ram is obtained.
