Abstract
Apparatus and method for collection, compaction, and ejection of refuse wherein refuse initially dumped into a forward hopper compartment is conducted through an opening in a compaction plate into a storage compartment. A shredding device such as an auger-type impeller is formed as part of the compaction blade assembly and is moveable therewith between a forward position in the hopper compartment and a rearward, compaction position in the storage compartment. The combined impeller and compaction blade assembly permits initial shredding and compaction of refuse during transmission to the storage compartment, with periodic compaction of the storage compartment contents by displacement of the compaction blade assembly rearward. Ejection of refuse from the storage compartment is also accomplished by rearward displacement of the impeller and compaction blade assembly, thereby forcing the contained refuse through a rearward ejection door.
