Abstract
A garbage compaction apparatus includes a packer housing having a loose garbage receiving bin and a compacted garbage storage bin. A packing channel communicates with both bins and has a ram reciprocally movable therein for moving garbage toward and into the storage bin. A movable wall within the storage bin is biased toward the outlet opening of the packing channel such that upon the accumulation of sufficient garbage within the storage bin, the insertion of additional garbage by the ram causes the wall to retract against the urging of the biasing mechanism whereby the accumulated garbage in the storage bin is maintained in a compacted state. The packer housing may be supported on a vehicle with the receiving bin situated forwardly of the storage bin and with the packing tube extended rearwardly to introduce garbage into the storage bin at the rearward end thereof so as to force the movable wall forwardly within the storage bin.
