Abstract
Abstract Apparatus for compacting material such as refuse including a sleeve for receiving the refuse to be compacted. The sleeve is used to line the inside of a bag so that upon completion of the compacting operation, removal of the sleeve from the bag leaves the compacted refuse in the bag for disposal as desired. The apparatus includes powered means for compacting the refuse in the bag and for withdrawing the sleeve from the bag.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
108 words
Apparatus for compacting and bagging refuse comprising: means for removably holding a lightweight bag in an upwardly open refuse receiving disposition; a tough sleeve removably lining the inside of the bag; and a single powered means including a ram for compacting refuse in the bag within said sleeve, said powered means being arranged to withdraw the ram from the compacted refuse and subsequently withdraw the sleeve from the bag upon completion of a compaction of a preselected quantity of refuse in the bag effectively without tearing the bag whereby the compacted refuse is retained in said bag substantially solely by the weight thereof as the sleeve is withdrawn.
Claim 2
Dependent Claim
108 words
Apparatus for compacting and bagging refuse comprising: means for removably holding a lightweight bag in an upwardly open refuse receiving disposition; a tough sleeve removably lining the inside of the bag; and a single powered means including a ram for compacting refuse in the bag within said sleeve, said powered means being arranged to withdraw the ram from the compacted refuse and subsequently withdraw the sleeve from the bag upon completion of a compaction of a preselected quantity of refuse in the bag effectively without tearing the bag whereby the compacted refuse is retained in said bag substantially solely by the weight thereof as the sleeve is withdrawn.
Claim 3
Dependent Claim
39 words
The compacting and bagging apparatus of claim 1 wherein said powered means defines means for moving said from above the open end of the bag downwardly thereto to effect compaction of the refuse in the bag within said sleeve.
Claim 4
Dependent Claim
43 words
The compacting and bagging apparatus of claim 1 wherein said powered means defines means for holding the sleeve above the open end of the bag upon withdrawal therefrom to permit horizontal movement from the apparatus of the bag with the compacted refuse therein.
Claim 5
Dependent Claim
71 words
The compacting and bagging apparatus of claim 1 wherein said powered means defines means for selectively moving the ram downwardly through the sleeve with the sleeve disposed in lining relationship to the bag to compact refuse in the lined bag, and moving the sleeve and ram upwardly from the bag to a position above the open end of the bag to permit removal of the bagged compacted refuse from the apparatus.
Claim 6
Dependent Claim
26 words
The compacting and bagging apparatuS of claim 1 wherein said holding means defines a circular horizontal cross section and said bag and sleeve are correspondingly round.
Claim 7
Dependent Claim
34 words
The compacting and bagging apparatus of claim 1 wherein said holding means comprises movable means for selectively disposing the bag in a compacting position within the apparatus and an exposed removal position outwardly thereof.
Claim 8
Dependent Claim
36 words
The compacting and bagging apparatus of claim 1 wherein said holding means comprises horizontally movable drawer means for selectively disposing the bag in a compacting position within the apparatus and an exposed removal position outwardly thereof.
Claim 9
Dependent Claim
37 words
The compacting and bagging apparatus of claim 1 wherein said sleeve includes an engagement portion at its upper end and said powered means includes means for engaging said engagement portion in withdrawing the sleeve from the bag.
Claim 10
Dependent Claim
39 words
The compacting and bagging apparatus of claim 1 wherein said sleeve includes an outturned flange portion at its upper end and said powered means includes means for engaging said outturned flange portion in withdrawing the sleeve from the bag.
Claim 11
Dependent Claim
15 words
The compacting and bagging apparatus of claim 1 wherein said sleeve is formed of metal.
Claim 12
Dependent Claim
91 words
Apparatus for compacting refuse comprising: a tubular sleeve; means defining an end wall; means for disposing the sleeve with one end adjacent the end wall; a ram; means for moving the ram through the sleeve for compacting refuse placed therein; and single powered means for moving the ram to a retracted position spaced from the compacted refuse and subsequently moving the sleeve from about the compacted refuse to about the retracted ram to dispose the sleeve in a withdrawn disposition permitting access to the compacted refuse for withdrawal from the apparatus.
Claim 13
Dependent Claim
91 words
Apparatus for compacting refuse comprising: a tubular sleeve; means defining an end wall; means for disposing the sleeve with one end adjacent the end wall; a ram; means for moving the ram through the sleeve for compacting refuse placed therein; and single powered means for moving the ram to a retracted position spaced from the compacted refuse and subsequently moving the sleeve from about the compacted refuse to about the retracted ram to dispose the sleeve in a withdrawn disposition permitting access to the compacted refuse for withdrawal from the apparatus.
Claim 14
Dependent Claim
19 words
The apparatus of claim 11 wherein means are providing for containing the refuse in a bag in the apparatus.
Claim 15
Dependent Claim
40 words
The apparatus of claim 11 wherein said powered means defines means for moving the ram away from the compacted refuse to a retracted position following each compacting operation for permitting placement of further refuse in the sleeve for compaction thereof.
Claim 16
Dependent Claim
61 words
The apparatus of claim 11 wherein said powered means defines means for moving the ram away from the compacted refuse to a retracted position following compacting operation for permitting placement of further refuse in the sleeve for compaction thereof and said powered means disposes said ram in said retracted position prior to the movement of the sleeve to said withdrawn disposition.
Claim 17
Dependent Claim
31 words
The apparatus of claim 11 wherein means are provided for moving the sleeve selectively below a compacting position adjacent the ram and a refuse receiving exposed position spaced from the ram.
