Abstract

Abstract Apparatus for compacting refuse comprising a fixed position compactor head, a portable refuse container having an open upper end and positionable below and in substantially vertical alignment with the head, and lift apparatus engageable with the container and operable to move the container upwardly to engage the refuse therein with the head so as to compact the refuse in the container. The lift apparatus consists of a cylinder assembly operated by water pressure and capable of maintaining a sustained force on the container over a period of time so that the refuse therein is subjected to a continuous compacting action by the head. A door operated valve controls the flow of water to the cylinder assembly.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 124 words
A refuse compactor comprising a fixed position head, a refuse container having an open upper end of a size to be telescoped over said head, said container being disposed below said head and having the open upper end thereof arranged in substantially vertical alignment with said head, lift apparatus engageable with said container and operable to move said container upwardly to engage refuse therein with said head, said lift apparatus being located entirely to one side of said container and said head and being operable to apply a continuous upward force to said container, said lift apparatus comprising a fluid actuated cylinder assembly having a fixed position cylinder and an upwardly extendible piston rod having transversely extending lift members thereon engageable with said container.
Claim 2
Dependent Claim 124 words
A refuse compactor comprising a fixed position head, a refuse container having an open upper end of a size to be telescoped over said head, said container being disposed below said head and having the open upper end thereof arranged in substantially vertical alignment with said head, lift apparatus engageable with said container and operable to move said container upwardly to engage refuse therein with said head, said lift apparatus being located entirely to one side of said container and said head and being operable to apply a continuous upward force to said container, said lift apparatus comprising a fluid actuated cylinder assembly having a fixed position cylinder and an upwardly extendible piston rod having transversely extending lift members thereon engageable with said container.
Claim 3
Dependent Claim 46 words
A refuse compactor according to claim 1 wherein said container is supported on wheels and has lift brackets thereon alignable with said lift members on said piston rod so that said lift members are movable upwardly into engagement with said lift brackets to lift said container.
Claim 4
Dependent Claim 46 words
A refuse compactor according to claim 1 further including a frame supporting said head and said cylinder, and guide means attached to said piston rod and supported on said frame for up and down movement in response to up and down movement of said piston rod.
Claim 5
Dependent Claim 77 words
A refuse compactor according to claim 3 further including a control valve for said cylinder operable to control the flow of pressure fluid to said cylinder, and door means mounted on said frame for movemenT between open and closed positions and connected to said valve means so as to provide for actuation thereof to move said piston rod upwardly on closing of said door means and move said piston rod downwardly on opening of said door means.
Claim 6
Dependent Claim 35 words
A refuse compactor according to claim 3 further including stop means on said guide means engageable with said container below the upper end thereof for maintaining said container in an upright position during lifting thereof.
