Abstract
Abstract A reference structure is adapted to be held in a substantially fixed location while a movable, self supporting, fluid tight, structure is variably positioned and expanded, at least in part, to and from the reference structure to move a ram. The ram inturn enters a receiving chamber to contact and compress refuse therein and compressibly move the compacting refuse into a compaction chamber. The ram moves as both fluid pressure generating and regulating apparatus are operated to expand and then to retract the self-supporting fluid tight structure. Various stages of compression are undertaken, as necessary, when a variable position reactive compression plate or baffle is sequentially moved away from the receiving chamber to define different volume sizes of temporary subcompartments within the compaction chamber which often serves as an ''''on the spot'''' refuse container.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A refuse compactor comprising a packer and a separable receiver, said packer comprising a boxlike frame having a reciprocable ram therein, a bellows-type ram actuator positioned between one wall of said frame and said ram and connected to said wall and the back of said ram, guide means on said frame for slidably positioning said ram slightly above the floor of said frame, an opening in the top of said frame for depositing refuse therein in front of said ram, a discharge opening in a wall of said frame adjacent the front of said ram, means to releasably connect the packer and the receiver, said receiver having mounted therein a separable adjustably positioned movable container, an opening in a wall of said receiver whereby when the packer and receiver are connected refuse may be packed from said packer through said receiver opening and into said container.
Claim 2
Dependent Claim
146 words
A refuse compactor comprising a packer and a separable receiver, said packer comprising a boxlike frame having a reciprocable ram therein, a bellows-type ram actuator positioned between one wall of said frame and said ram and connected to said wall and the back of said ram, guide means on said frame for slidably positioning said ram slightly above the floor of said frame, an opening in the top of said frame for depositing refuse therein in front of said ram, a discharge opening in a wall of said frame adjacent the front of said ram, means to releasably connect the packer and the receiver, said receiver having mounted therein a separable adjustably positioned movable container, an opening in a wall of said receiver whereby when the packer and receiver are connected refuse may be packed from said packer through said receiver opening and into said container.
Claim 3
Dependent Claim
65 words
A refuse compactor, as claimed in claim 1, comprising, in addition, an air pump secured to the boxlike frame, conduits connecting the air pump and the bellows-type ram actuator, and control valves positioned in the conduits, and operated with the air pump which then alternately and effectively serves as a pressure source and as a vacuum inducer, respectively, expanding and contracting the bellows-type ram actuator.
Claim 4
Dependent Claim
70 words
A refuse compactor, as claimed in claim 1, wherein the said opening in the wall of said receiver is selectively closed by a door equipped with an outward projecting means to be engaged by the ram during a final compacting cycle, whereby the door moves into closed position and upon subsequent separation of the receiver from the packer, all the refuse remains within the receiver until it is intentionally emptied.
