Abstract
Abstract A container is located below a refuse chute and a gate unit in the chute is opened to allow refuse to discharge from the chute into the container. The container is then moved to a compacting station wherein the refuse in the container is compacted. If the compacted refuse is below a predetermined level in the container, the container is moved back below the chute and the gate unit opened to allow further refuse to fall within the container. This procedure is repeated until the level of the compacted refuse in the container reaches a predetermined level. Then the full container is ejected from the system, and empty container is moved below the chute and the gate unit is operated as above to allow further refuse to fall in the empty container. The gate unit may be operated in response to refuse falling. Alternatively, the apparatus is operated by means of a timer at predetermined times.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
197 words
Compacting system for compacting material in a container comprising: a receiving station includinG a chute for receiving a gate unit in said receiving station operable for selectively closing and opening said chute for selectively feeding said material to be compacted into said container; a compacting station including level sensing means for sensing the level of compacted material in said container; and open-ended transport means between said receiving station and said compacting station for moving said container to said compacting station along a first given path after said gate unit closes, said material in said container being compacted at said compacting station, said transport means moving said container back to said receiving station for receiving further material to be compacted when the level of the compacted material in said container is below a predetermined level, and ejecting said container from said compacting system when the level of the compacted material in said container is above said predetermined level, said transport means further including open-ended means for moving an empty container to said receiving station along a second given path which is independent of said first given path when said first mentioned container is ejected from said compacting system.
Claim 2
Dependent Claim
197 words
Compacting system for compacting material in a container comprising: a receiving station includinG a chute for receiving a gate unit in said receiving station operable for selectively closing and opening said chute for selectively feeding said material to be compacted into said container; a compacting station including level sensing means for sensing the level of compacted material in said container; and open-ended transport means between said receiving station and said compacting station for moving said container to said compacting station along a first given path after said gate unit closes, said material in said container being compacted at said compacting station, said transport means moving said container back to said receiving station for receiving further material to be compacted when the level of the compacted material in said container is below a predetermined level, and ejecting said container from said compacting system when the level of the compacted material in said container is above said predetermined level, said transport means further including open-ended means for moving an empty container to said receiving station along a second given path which is independent of said first given path when said first mentioned container is ejected from said compacting system.
