Abstract
Abstract Disclosed is a compactor for loose material such as garbage, including a compacting chamber having a feed opening and a discharge opening; an outwardly tapering discharge funnel; gate means operable for closing and opening the discharge opening; a hydraulic ram operable to compact the loose material in the chamber when the gate is closed and to expel a major portion of the compacted material when the gate is open; means for selfcleaning the gate and means for controlling the operation of the gate and of the ram.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
169 words
A compactor for use in compacting and discharging loose material comprising, in combination a compacting chamber structure having a feed opening for receiving said material and a discharge opening spaced apart from said feed opening, gate means movable on a plane for opening and closing said discharge opening, operating means operable to compact in a first compacting direction the loose material in the chamber to a predetermined density when the gate means is closed and respectively to discharge the compacted material out of the compacting chamber through said discharge opening when said gate means is subsequently opened to the extent that the rear end of the compacted material after the discharge operation will be positioned in the compacting chamber and within the plane of movement of said gate means, said gate means being arranged and adapted to hold and compact the compacted material in a second compacting direction substantially askew to the compacting direction of said operating means when said gate means is moved to close said discharge opening.
Claim 2
Dependent Claim
169 words
A compactor for use in compacting and discharging loose material comprising, in combination a compacting chamber structure having a feed opening for receiving said material and a discharge opening spaced apart from said feed opening, gate means movable on a plane for opening and closing said discharge opening, operating means operable to compact in a first compacting direction the loose material in the chamber to a predetermined density when the gate means is closed and respectively to discharge the compacted material out of the compacting chamber through said discharge opening when said gate means is subsequently opened to the extent that the rear end of the compacted material after the discharge operation will be positioned in the compacting chamber and within the plane of movement of said gate means, said gate means being arranged and adapted to hold and compact the compacted material in a second compacting direction substantially askew to the compacting direction of said operating means when said gate means is moved to close said discharge opening.
Claim 3
Dependent Claim
43 words
A compactor according to claim 1 wherein said feed opening is located at the top of said compacting chamber and said discharge opening in a lateral wall of said chamber, and said gate means being movable in the plane of said discharge opening.
Claim 4
Dependent Claim
43 words
A compactor according to claim 2 wherein said operating means includes a ram communicating with said compacting chamber opposite said discharge opening and being arranged for reciprocating movement through said compacting chamber to a close proximity of the plane of said discharge opening.
Claim 5
Dependent Claim
30 words
A compactor according to claim 3 wherein the length of said ram corresponds at least to the length of said compacting chamber in the direction of movement of said ram.
Claim 6
Dependent Claim
20 words
A compactor according to claim 3 wherein a portion of said ram facing said feed opening has a converging configuration.
Claim 7
Dependent Claim
19 words
A compactor according to claim 3 further comprising hydraulic means for driving said gate means and said ram respectively.
Claim 8
Dependent Claim
34 words
A compactor according to claim 6 further comprising programming switch means operatively connected to said hydraulic means for controlling the actuation of said gate means and of said ram according to a predetermined program.
Claim 9
Dependent Claim
27 words
A compactor according to claim 6 wherein said hydraulic means incluDes a hydraulic piston and cylinder systems connected to said ram and to said gate blade, respectively.
Claim 10
Dependent Claim
38 words
A compactor according to claim 8 further comprising a pushing bracket connected to the front interior of said ram, said pushing bracket having a U-shaped slot for removably coupling the piston of said hydraulic piston and cylinder system.
Claim 11
Dependent Claim
14 words
A compactor according to claim 3 wherein said ram means is movable on rollers.
Claim 12
Dependent Claim
23 words
A compactor according to claim 3 wherein said operating means includes pneumatic drive means for driving said gate means and said ram, respectively.
Claim 13
Dependent Claim
20 words
A compactor according to claim 1 further comprising an outwardly tapering funnel connected to the periphery of said discharge opening.
Claim 14
Dependent Claim
24 words
A compactor according to claim 12 wherein the outside periphery of said funnel is arranged for supporting an inlet portion of a garbage bag.
Claim 15
Dependent Claim
59 words
A compactor according to claim 1 wherein said gate means includes a pair of upright guiding grooves arranged near said discharge opening, a gate blade disposed for upright movement in said grooves, the lower ends of said grooves terminating at a distance from the bottom of said discharge opening to permit self-cleaning of the path of said gate blade.
Claim 16
Dependent Claim
56 words
A compactor according to claim 14, wherein a lower portion of said gate blade in the closed position projecting downwardly beyond the lower ends of said grooves is spaced apart from the walls of said discharge opening whereby the resulting lateral steps on the gate blade expel any material that may have accumulated in said grooves.
Claim 17
Independent Claim
150 words
A method of cyclically compacting loose material within a compacting chamber having a discharge opening and a gate arranged for covering and uncovering the discharge opening comprising the steps of a. closing said gate b. feeding said material into said chamber c. compacting said material in said chamber in a first compaction direction by subjecting it to a predetermined pressure against said closed gate d. releasing the compacting pressure and e. subsequently opening said gate and f. pushing the compacted material through said discharge opening out of said chamber to the extent that at least a portion of the compacted material after the discharge operation will be positioned in said chamber and within the path of movement of said gate g. compacting at least a portion of the compacted material in a second compaction direction substantially askew to the first compaction direction by closing said gate against said compacted material.
Claim 18
Independent Claim
150 words
A method of cyclically compacting loose material within a compacting chamber having a discharge opening and a gate arranged for covering and uncovering the discharge opening comprising the steps of a. closing said gate b. feeding said material into said chamber c. compacting said material in said chamber in a first compaction direction by subjecting it to a predetermined pressure against said closed gate d. releasing the compacting pressure and e. subsequently opening said gate and f. pushing the compacted material through said discharge opening out of said chamber to the extent that at least a portion of the compacted material after the discharge operation will be positioned in said chamber and within the path of movement of said gate g. compacting at least a portion of the compacted material in a second compaction direction substantially askew to the first compaction direction by closing said gate against said compacted material.
Claim 19
Dependent Claim
24 words
