1. A refuse compaction device, comprising:
- a housing having at one end a hopper section for receiving refuse material to be compacted and at the other end a compaction section for compacting refuse into a densified plug;
said compaction section communicating with said hopper section for receiving refuse material therefrom and having a refuse material discharge opening;
a rotatable auger screw extending through said hopper section and at least partly into said compaction section for compacting refuse material therein, said auger screw being mounted in cantilever fashion in an end wall of said hopper remote from said compaction section;
means mounting said auger screw in said housing for limited angular movement in all directions from its normal axis of rotation;
said auger screw being adapted to be drivingly connected to power means for rotatably driving said auger screw.

Abstract
The specification describes a refuse compacting device of the auger type including a housing having a hopper section at one end for receiving refuse material to be compacted and a compaction section at the other end for compacting refuse received from the hopper section into a densified plug, a rotatable auger screw extending through the hopper section and partly into the compaction section wherein the auger screw is resiliently mounted in the housing for limited angular movement in all directions from its normal axis of rotation so as to permit processing of materials which cannot otherwise be processed and to reduce the possibility of blockages.

31. A refuse compaction device comprising:
-
an elongated generally cylindrical housing having a wall at one end defining a closed rearward end and an open forward end; a gravity feed hopper section at said rearward end having a refuse intake opening and a compaction section at said forward end, said compaction section communicating with said hopper section for receiving refuse material therefrom, said open forward end of said housing defining a refuse material discharge opening; an auger screw mounted in cantilever fashion in said wall and extending axially through said hopper section from said wall and into said compaction section, said auger screw being effective to convey refuse material received in said hopper to said compaction section and compact the refuse material therein; power means; said auger screw being secured to and rotatably driven by said power means; and
,means mounting said auger screw in said wall for rotation about a normal axis concentric with the axis of said housing and for resilient angular displacement in all directions from said normal axis upon application of a predetermined normal force to said auger screw. - View Dependent Claims (32, 33)

34. A refuse compaction device comprising:
-
an elongated generally cylindrical housing having a wall at one end defining a closed rearward end and an open forward end defining a refuse material discharge opening; means for supporting said housing on a support surface; said housing further having a gravity feed hopper section at said rearward end having a generally rectangular refuse material intake opening defined by a pair of flat side walls, a upwardly and rearwardly inclined rear wall and a rearwardly, and upwardly inclined front wall and a compaction section communicating with said hopper section for receiving refuse therefrom; a rotatable auger screw adapted to extend axially through said hopper section and partly into said compaction section and being effective to convey refuse material from said hopper to said compaction section and compact refuse material in said compaction section, said auger screw having a shank portion and first and second flight sections formed on said shank portion, said first portion in and extending throughout said hopper section and having a pitch substantially equal to the longitudinal dimension of said intake opening, said second flight portion being continuous with said first flight portion and having a pitch which is less than that of said first portion, said shank portion having an extension which projects forwardly of the forwardmost end of said second flight section; a power means; said auger screw being secured to and rotatably driven by said power means; means for mounting said auger screw and power means in cantilever fashion in said wall for rotation about a normal axis of rotation concentric with the axis of said housing and permitting resilient angular displacement of said auger screw and power means from said normal axis of rotation to permit passage of refuse material between said housing and auger screw; and
,means for maintaining a substantially constant force upon a densified plug of refuse material produced in said compaction section.
