Abstract
Abstract A waste compactor comprising a longitudinally extending compaction chamber, having a discharge opening at its leading end and a feed opening at its trailing end. A chute communicating with the feed opening is provided by which delivery of refuse may be made to the chamber. A horizontally moveable ram is mounted to the rear of the trailing end of the chamber and is reciprocably moveable from a first position forward of the feed opening to a second retracted position to the rear of the feedopening, thereby to successively move the refuse toward the discharge opening. At least a portion of the compression chamber located between the feed and discharge openings is provided with a plurality of elongated flutes extending substantially along the path of movement of the refuse and radially extending through the inner surface of the chamber toward the center thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A waste compactor comprising a tubular chamber having a uniform cross-section along its length, said chamber having a discharge opening at its leading end and a feed opening at its trailing end, a chute communicating with the feed opening for delivery of refuse thereto, a ram longitudinally moveable between a first position to the rear of the feed opening and a second position forward of said feed opening to move said refuse into said chamber and along the inner surface thereof forward to said discharge opening, the portion of the chamber located between said second position and said discharge opening having a plurality of elongated flutes spaced from each other and each extending substantially along the path of movement of said refuse and extending from the inner surface of said chamber toward the center thereof, said flutes extending radially within said chamber an amount sufficient to substantially decrease the crosssectional area of said chamber while simultaneously increasing the contact surface uniformly between said second position and said discharge opening, thereby to compact said refuse on movement from the second position to said discharge opening.
Claim 2
Dependent Claim
184 words
A waste compactor comprising a tubular chamber having a uniform cross-section along its length, said chamber having a discharge opening at its leading end and a feed opening at its trailing end, a chute communicating with the feed opening for delivery of refuse thereto, a ram longitudinally moveable between a first position to the rear of the feed opening and a second position forward of said feed opening to move said refuse into said chamber and along the inner surface thereof forward to said discharge opening, the portion of the chamber located between said second position and said discharge opening having a plurality of elongated flutes spaced from each other and each extending substantially along the path of movement of said refuse and extending from the inner surface of said chamber toward the center thereof, said flutes extending radially within said chamber an amount sufficient to substantially decrease the crosssectional area of said chamber while simultaneously increasing the contact surface uniformly between said second position and said discharge opening, thereby to compact said refuse on movement from the second position to said discharge opening.
Claim 3
Dependent Claim
85 words
The waste compactor according to claim 1, wherein said elongated chamber is of circular cross-section and said flutes are uniform in cross section and extend radially inward towards the center thereof, the number of flutes being determined by the ratio of its radial extent from the surface of said chamber with respect to the chordal extent between the ends of its bases attached to said surface provided that the radial extent is less than the distance from the surface of the center of said chamber.
Claim 4
Dependent Claim
31 words
The refuse compactor according to claim 2, wherein each of said flutes are triangular in cross-section and are equidistantly spaced about the inner wall of said compression chamber from the others.
Claim 5
Dependent Claim
17 words
The refuse compactor according to claim 2 wherein each of said flutes are polygonal in cross section.
Claim 6
Dependent Claim
30 words
The refuse compactor according to claim 2, wherein each of said flutes are spirally formed and arranged in parallel with each other along the inner walls of said compression chamber.
Claim 7
Dependent Claim
32 words
The refuse compactor according to claim 2, wherein each of said flutes are provided with a bevelled edge at their ends adjacent said second position to provide a lead-in for said refuse.
Claim 8
Dependent Claim
35 words
The refuse compactor according to claim 2, wherein the chordal distance between the radial inner portions of adjacent flutes is equal to or greater than the chordal distance between the bases of the adjacent flutes.
Claim 9
Dependent Claim
29 words
The refuse compactor according to claim 2 wherein the line extension of each of the base ends of said flutes are not parsllel and meet exteriorly of said chamber.
Claim 10
Dependent Claim
112 words
The refuse compactor according to claim 1, including means for successively reciprocating said ram on delivery of refuse to said feed opening, said ram and said flutes acting on said refuse cooperatingly to compress said refuse into a continuous stream having successive laminar portions formed corresponding to each delivery of refuse, and wherein the compression section of said compactor is supported on a base and is cantilevered with respect thereto to be freely spaced frOm the floor, a substantially endless tubular bag material mounted over the compression section, said tubular bag being adapted to be cut and tied at selective intervals between refuse laminae on the discharge of refuse from said compactor.
