Abstract

Abstract A unitary refuse transfer station that is transportable on or as a highway vehicle from fabrication site to destination. The station comprises an elongated pit-like structure with an open top into which refuse may be dumped from route collection trucks. The main structure is originally fabricated with an outside width determined by the maximum width of a vehicle which may travel on the public highways. The pit-like structure has one or more hopper forming wings which are positioned within the structure when the entire station is being transported from factory to destination and which are swung up and out to widen its open top after positioning at the destination. Means are provided for supporting the structure at a desired ground related level. All auxiliary equipment and structural support means are also carried within the main structure during transportation. There is a transverse plate that is movable through the structure to push the refuse to one end. A compaction device has its receiving chamber at and beneath an opening in the bottom of the pit structure at that end of the structure and a ram which reciprocates through the chamber for compressing the refuse in the chamber and forcing it into a large portable container. When loaded, the portable container is moved to a dump or incinerator.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 175 words
A unitary transfer station comprising, in combination, an elongated, pit-like structure having a bottom, parallel vertical side walls and vertical end walls, means on said structure for removably supporting said structure on a highway vehicle, a transversely extending, generally vertical push plate in said structure, co-operating means for guiding said plate for movement longitudinally through said structure, power means for moving said plate, at least one hopper wing extending along the longitudinal upper edge of said structure and movable from a position within said structure to a position extending upwardly and outwardly from the respective edge, a compaction device mounted by said structure, said device having a receiving hopper, an ejection opening, a ram and means for reciprocating said ram through said receiving hopper toward said ejection opening, there being an opening at one end of the said bottom of said structure into said receiving hopper, means adjacent said ejection opening for coupling a receiving container in mating relation thereto and structure for supporting said station and said wing at a selected ground related level.
Claim 2
Dependent Claim 175 words
A unitary transfer station comprising, in combination, an elongated, pit-like structure having a bottom, parallel vertical side walls and vertical end walls, means on said structure for removably supporting said structure on a highway vehicle, a transversely extending, generally vertical push plate in said structure, co-operating means for guiding said plate for movement longitudinally through said structure, power means for moving said plate, at least one hopper wing extending along the longitudinal upper edge of said structure and movable from a position within said structure to a position extending upwardly and outwardly from the respective edge, a compaction device mounted by said structure, said device having a receiving hopper, an ejection opening, a ram and means for reciprocating said ram through said receiving hopper toward said ejection opening, there being an opening at one end of the said bottom of said structure into said receiving hopper, means adjacent said ejection opening for coupling a receiving container in mating relation thereto and structure for supporting said station and said wing at a selected ground related level.
Claim 3
Dependent Claim 45 words
A unitary transfer station according to claim 1 wHich the power means for moving the push plate and the means for reciprocating the ram are hydraulic cylinders and which has a hydraulic power unit mounted on structure and connected through valving to said hydraulic cylinders.
