Garbage compaction truck

Claim 1

A garbage compaction apparatus comprising, a packer housing including a top wall, bottom wall, opposite side walls and forward and rearward end walls, said housing including a compacted garbage storage bin and a loose garbage receiving bin situated forwardly of said storage bin, a packing channel having an inlet opening in communication with said receiving bin for receiving garbage therefrom and an outlet opening in communication with said storage bin for delivering garbage thereto, said packing channel comprising an elongated tube extended longitudinally of said storage bin adjacent said bottom wall, said outlet opening comprising an open rearward end of said tube and being positioned adjacent a rearward portion of said storage chamber, a ram reciprocally movable within said packing channel, means for moving said ram between a retracted position wherein garbage may be received into said channel through said inlet opening and a compacting position wherein said garbage received in said channel is moved toward said outlet opening, said outlet opening facing said rearward wall and said rearward wall comprising an arcuate generally semi-cylindrical surface having a lower end in general alignment with said tube whereby garbage extruded rearwardly through said outlet opening by said ram is directed along the periphery of said rearward wall upwardly and forwardly into said storage bin, a movable wall within said storage bin, means for biasing said movable wall against retracting movement in a forward direction, said ram being operative, in response to reciprocal movement thereof, to accumulate sufficient garbage within said storage bin that rearward movement of additional garbage toward said outlet opening by said ram forces the accumulated garbage within said storage bin upwardly and forwardly to move said movable wall in a retracting forward direction against the urging of said biasing means whereby said accumulated garbage in said storage bin is maintained in a compacted state.
