Abstract
Abstract A refuse compactor arranged for automatically moving the drawer from a compacting position toward an exposed refuse-receiving position. The movement is effected herein by modified operation of the compacting ram structure. More specifically, the automatic movement of the drawer is effected by the operation of the power drive provided for operating the ram normally between compacting and retracted positions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
118 words
In a refuse compactor having a receptacle for receiving refuse to be compacted, means for movably mounting the receptacle for selective manual positioning in a compacting position and an exposed refuse-receiving position, a ram, and powered means for selectively moving the ram in a compacting cycle from a retracted position into said receptacle in said compacting position for compacting refuse in the receptacle, said powered means returning the ram to the retracted position with the receptacle retained in the compacting position upon completion of the compacting cycle, the improvement comprising means for selectively causing an operation of said powered means in an opening cycle to cause said receptacle to move from said compacting position toward said exposed position.
Claim 2
Dependent Claim
118 words
In a refuse compactor having a receptacle for receiving refuse to be compacted, means for movably mounting the receptacle for selective manual positioning in a compacting position and an exposed refuse-receiving position, a ram, and powered means for selectively moving the ram in a compacting cycle from a retracted position into said receptacle in said compacting position for compacting refuse in the receptacle, said powered means returning the ram to the retracted position with the receptacle retained in the compacting position upon completion of the compacting cycle, the improvement comprising means for selectively causing an operation of said powered means in an opening cycle to cause said receptacle to move from said compacting position toward said exposed position.
Claim 3
Dependent Claim
32 words
The refuse compactor structure of claim 1 wherein said means for causing said receptacle to move comprises means responsive to movement of said ram by said powered means to a receptacle-opening disposition.
Claim 4
Dependent Claim
55 words
The refuse compactor structure of claim 1 wherein said means for causing said receptacle to move comprises means for causing said ram selectively to have movement different in said opening cycle from the refuse-compacting movement in said compacting cycle and means responsive to said different movement of the ram to cause said receptacle to move.
Claim 5
Dependent Claim
62 words
The refuse compactor structure of claim 1 wherein said means for causing said receptacle to move comprises means for causing said ram selectively to move away from said receptacle in said opening cycle to an extreme outer disposition, and means responsive to said movement of the means away from the receptacle to said extreme outer disposition to cause said receptacle to move.
Claim 6
Dependent Claim
37 words
The refuse compactor structure of claim 1 wherein said means for causing said receptacle to move comprises yieldable means permitting full movement of the powered means notwithstanding a stuck condition of the receptacle in the compacting position.
Claim 7
Dependent Claim
46 words
The refuse compactor structure of claim 1 wherein said powered means includes electrical drive means and said means for causing said receptacle to move comprises electrical control means selectively operable to cause said drive means to operate in an opening cycle differing from the compacting cycle.
Claim 8
Dependent Claim
108 words
In a refuse compactor having a receptacle for receiving refuse to be compacted, means for movably mounting the receptacle for selective positioning in a compacting position and an exposed refuse-receiving position, and powered means including a ram selectively movable in a compacting cycle into said receptacle in said compacting position for compacting refuse in the receptacle, the improvement comprising means for causing said receptacle to move from said compacting position toward said exposed position as an incident of operation of said powered means in an opening cycle, including manually operable selector means for causing said powered means selectively to cause a compacting cycle or a receptacle opening cycle.
Claim 9
Dependent Claim
108 words
In a refuse compactor having a receptacle for receiving refuse to be compacted, means for movably mounting the receptacle for selective positioning in a compacting position and an exposed refuse-receiving position, and powered means including a ram selectively movable in a compacting cycle into said receptacle in said compacting position for compacting refuse in the receptacle, the improvement comprising means for causing said receptacle to move from said compacting position toward said exposed position as an incident of operation of said powered means in an opening cycle, including manually operable selector means for causing said powered means selectively to cause a compacting cycle or a receptacle opening cycle.
Claim 10
Dependent Claim
24 words
The refuse compactor structure of claim 7 wherein said powered means comprises electrical drive means and said selector means comprises manually operable switch means.
Claim 11
Dependent Claim
60 words
The refuse compactor structure of claim 7 wherein said powered means comprises electrical drive means including switch means for initiating operation of the drive means, and said selector means comprises manually operable switch means electrically associated with said drive means, and switch means for causing the operation of the drive means initiated thereby to be selectively either of said cycles.
Claim 12
Dependent Claim
94 words
The refuse compactor structure of claim 7 wherein said powered means comprises electrical drive means including switch means for initiating operation of the drive means, and said selector means comprises manually operable switch means electrically associated with said drive means and switch means for causing the operation of the drive means initiated thereby to be selectively either of said cycles, said selector switch means being operable independently of said operation initiating switch means to permit selecting the mode of operation prior to effecting the same by subsequent operation of said operation initiation switch means.
Claim 13
Dependent Claim
83 words
The refuse compactor structure of claim 7 wherein said powered means comprises electrical drive means including switch means for initiating operation of the drive means, and said selector means comprises manually operable switch means electrically associated with said drive means and switch means for causing the operation of the drive means initiated thereby to be selectively either of said operation cycles, said selector switch means being arranged to effect operation of said operation initiation switch means following operation of said selector switch means.
