Abstract
Abstract An automatic refuse compaction system includes a compactor unit having first and second stages of refuse compaction operating respectively vertically and horizontally in sequence. Refuse is compacted in a compaction chamber from which it is discharged automatically into a receptacle. The refuse compaction stages and discharge means are all pneumatically controlled. Automatic means for increasing compaction pressure in the second stage of compaction is provided. Pneumatically operated devices for discharging deodorant, insecticide and fire extinguishing fluid on the refuse are also provided. A plurality of compactor units can be connected in a pneumatic circuit with a single source of compressed air and programmed selector means for delivering air under pressure to each compactor unit in turn requiring compressed air.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
277 words
An automatic refuse compaction system, comprising a duct for receiving refuse deposited therein, said duct having an open top, closed bottom and open lateral end; first compaction means movably disposed in said duct to press vertically downward on a pile of refuse at the bottom of the duct to effect a first stage of compaction; means for retracting said first compaction means laterally in the duct to clear the duct and permit passage of refuse past the first compaction means to the bottom of the duct; a compaction chamber having an end wall and opening into said lateral end of Said duct for receiving refuse therefrom; second compaction means movable horizontally transversely of the duct to push refuse through said open lateral end of the duct and to compress the refuse in said compaction chamber against said end wall while said first compaction means remains stationary to hold down the refuse in the duct during movement of said second compaction means; pneumatically actuated valve means; pneumatically actuated control means pneumatically connected to said valve means to operate the same; sensing means in said duct arranged to detect vertical passage of refuse therethrough: pneumatic switch means operatively interconnecting said sensing means and said pneumatic control means to actuate the same so that the first compaction means is operated when refuse deposited in the duct is detected by said sensing means; fluid conducting means operatively connecting said valve means in circuit with said second compaction means for operating and controlling the same cyclically; and pneumatic means operatively connecting said pneumatic control means and said first compaction means, so that the first and second compaction means operate cyclically in sequence.
Claim 2
Dependent Claim
277 words
An automatic refuse compaction system, comprising a duct for receiving refuse deposited therein, said duct having an open top, closed bottom and open lateral end; first compaction means movably disposed in said duct to press vertically downward on a pile of refuse at the bottom of the duct to effect a first stage of compaction; means for retracting said first compaction means laterally in the duct to clear the duct and permit passage of refuse past the first compaction means to the bottom of the duct; a compaction chamber having an end wall and opening into said lateral end of Said duct for receiving refuse therefrom; second compaction means movable horizontally transversely of the duct to push refuse through said open lateral end of the duct and to compress the refuse in said compaction chamber against said end wall while said first compaction means remains stationary to hold down the refuse in the duct during movement of said second compaction means; pneumatically actuated valve means; pneumatically actuated control means pneumatically connected to said valve means to operate the same; sensing means in said duct arranged to detect vertical passage of refuse therethrough: pneumatic switch means operatively interconnecting said sensing means and said pneumatic control means to actuate the same so that the first compaction means is operated when refuse deposited in the duct is detected by said sensing means; fluid conducting means operatively connecting said valve means in circuit with said second compaction means for operating and controlling the same cyclically; and pneumatic means operatively connecting said pneumatic control means and said first compaction means, so that the first and second compaction means operate cyclically in sequence.
Claim 3
Dependent Claim
64 words
An automatic refuse compaction system as defined in claim 1, further comprising pneumatic deodorant spray means and pneumatic insectide discharge means disposed in said duct for deodorizing and disinfecting refuse therein, said deodorant spray means and said insectide discharge means being connected to said pneumatic control means for actuation thereby in coordination with operation of either one of the first and second compaction means.
Claim 4
Dependent Claim
149 words
An automatic refuse compaction system as defined in claim 1, further comprising a source of fire extinguishing fluid connected to said duct; pneumatically controlled valve means connected to said source of fire extinguishing fluid for controlling discharge of said fluid into the duct; fire detection means disposed in said duct, both said fire detection means and said valve means being connected to said pneumatic control means so that said fire extinguishing fluid is discharged into the duct when a fire in the duct is detected by said fire detection means, said pneumatic control means being so arranged that both the first and second compaction means are actuated and remain stationary in actuated position when fire is detected in the duct and while said fluid is being discharged into the duct, to cut off air from the fire in the duct and to compress the burning refuse in the duct.
Claim 5
Dependent Claim
70 words
An automatic refuse compaction system as defined in claim 1, wherein said first compaction means comprises hinged, cooperating compactor plates arranged to pivot in said duct between vertical and horizontal positions, said plates clearing the duct to permit passage of refuse while the plates are in vertical position, said plates applying downward pressure on the refuse at the bottom of the duct when the compactor plates are in horizontal position.
Claim 6
Dependent Claim
51 words
An automatic refuse compaction system as defined in claim 1, further comprising pneumatic drive means connected to said first compaction means; and fluid drive means connected to said second compaction means, both drive means being operatively connected to said pneumatic control means for actuation thereby in a prescribed program of operation.
Claim 7
Dependent Claim
103 words
An automatic refuse compaction system as defined in claim 5, further comprising fluid containing tank chambers connected in a fluid circuit with said fluid drive means for passing fluid to and from said fluid drive means; said pneumatically actuated valve means being disposed in said fluid circuit for controlling passage of said fluid at predetermined pressures to and from said fluid drive means; and pressure booster means connected in said fluid circuit for increasing pressure of fluid in said fluid drive means in the event that said second compaction means encounters excessive resistance while moving refuse from the duct to said compaction chamber.

Claim 9
Dependent Claim
63 words

An automatic refuse compaction system as defined in claim 8, wherein said second compaction means comprises a circular compactor head; and further comprising guide means at said lateral end of the duct to prevent deflection of said head when the head approaches said lateral end of the duct while compacting refuse in said compaction chamber; said compaction chamber having an open bottom, said refuse discharge means comprising a pneumatically operated door at the bottom of said compaction chamber, said door being arranged to be opened when refuse is fully compacted in said compaction chamber; a movable plate at the top of said compaction chamber for pushing compacted refuse out of the compaction chamber while said door is opened, said plate being arranged to clear said compactor head of refuse while said plate pushes compacted refuse out of the compaction chamber; and pneumatic drive means operatively connected to said door and to said movable plate for operating the same, said pneumatic drive means being further connected in a pneumatic circuit with said pneumatic control means for actuation thereby when the compactor head is located at said one lateral end of the duct.
