Abstract
Abstract Method and apparatus for compacting refuse in accordance with which the refuse is fed by means of a pair of converging conveyors into a press chamber where it is compressed by the ram of a hydraulic cylinder assembly against a fixed wall at one end of the chamber. The refuse, when compressed, comprises a block of high density, on the order of 1,500 to 2,400 pounds per cubic yard, disposed within a rectangular slide box which forms one end of the press chamber. This slide box, containing the high density block of compressed refuse, is then caused to move laterally to a position adjacent the remainder of the press chamber where the high density block is removed; whereupon the slide box moves back into alignment with the remainder of the press chamber preparatory to a succeeding compaction cycle. The apparatus is characterized in that the compaction takes place in stages of increasingly greater force. In the first stage, the press ram moves rapidly into the press chamber under relatively little force. Then, as the density of the refuse increases, the ram slows down in one or more stages as the force it exerts increases. This materially increases the speed of the compaction process, a factor vital to a commercially economical system for disposing of large amounts of refuse.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
210 words
In apparatus for compacting refuse of widely varying density into a shallow depth compact adapted to be stacked and baled with similar compacts to form a composite bale of substantially uniform density, the combination of a press chamber for receiving low density refuse to be compacted, a ram movable into said chamber to compact said refuse against an end wall of said chamber, a shallow depth slide box at the end of said chamber adjacent said end wall and having an opening adapted to confront said chamber and which receives a shallow depth refuse compact formed by said ram, means for moving said slide box along an essentially straight line path from a position where its opening is in alignment with the remainder of the press chamber to a position where said opening is located laterally of the remainder of said press chamber, means operable when the opening in said slide box is located laterally of the remainder of said press chamber for removing a refuse compact formed therein, and means for automatically varying the size of the inlet opening of said refuse into said chamber in response to variations in density of said refuse so as to provide substantially constant density as it is being introduced into said chamber.
Claim 2
Dependent Claim
210 words
In apparatus for compacting refuse of widely varying density into a shallow depth compact adapted to be stacked and baled with similar compacts to form a composite bale of substantially uniform density, the combination of a press chamber for receiving low density refuse to be compacted, a ram movable into said chamber to compact said refuse against an end wall of said chamber, a shallow depth slide box at the end of said chamber adjacent said end wall and having an opening adapted to confront said chamber and which receives a shallow depth refuse compact formed by said ram, means for moving said slide box along an essentially straight line path from a position where its opening is in alignment with the remainder of the press chamber to a position where said opening is located laterally of the remainder of said press chamber, means operable when the opening in said slide box is located laterally of the remainder of said press chamber for removing a refuse compact formed therein, and means for automatically varying the size of the inlet opening of said refuse into said chamber in response to variations in density of said refuse so as to provide substantially constant density as it is being introduced into said chamber.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1 including a door formed in a side of said press chamber, said last named meanS comprising belt conveyor means for simultaneously varying the density, pre-compacting and feeding refuse into said chamber through said door when opened.
Claim 4
Dependent Claim
49 words
The apparatus of claim 2 wherein said belt conveyor means comprises two vertically spaced belt conveyors which are variably tapered toward each other near said door automatically in response to the density of the refuse so as to pre-compact the refuse at substantially constant density before entering said chamber.
Claim 5
Dependent Claim
27 words
The apparatus for claim 3 together with means for adjusting the degree of tapering of said spaced conveyors so as to selectively adjust the density of pre-compacting.
Claim 6
Dependent Claim
46 words
The apparatus of claim 2 wherein said door is hinged to the sidewall of said chamber, together with a small open space in said side of said chamber immediately above said door for permitting projection of excess refuse from said chamber when said door is closed.
Claim 7
Dependent Claim
32 words
The apparatus of claim 1 together with a plurality of operating cylinders connected to said ram for applying selectively greater pressures in said press chamber as the refuse is being increasingly compacted.
Claim 8
Dependent Claim
51 words
The apparatus of claim 2 wherein said pre-compaction is at a ratio of at least about 2 to 1, together with cooperable shear blades, one secured to the side of said ram and the other, to the top of said door for shearing refuse therebetween by downward movement of said ram.
Claim 9
Dependent Claim
39 words
The apparatus of claim 1 together with means exteriorly of said chamber for constraining and preventing substantial expansion of refuse compacts discharged from said box and as they are stacked one upon the other prior to forming a bale.
Claim 10
Dependent Claim
36 words
The apparatus of claim 7 together with a plurality of operating cylinders selectively connectable to said ram for applying selectively greater pressures in said press chamber at lesser speeds as the refuse is being increasingly compacted.
