Abstract
Abstract A control arrangement for a refuse compactor in which a photocell cooperates with a time delay device to determine when refuse is being accumulated or has been accumulated in an accumulating chamber for eventual compaction into a bale. A hydraulic cylinder and piston is actuated thereupon to compact the refuse. After the compacted mass is realized, an ejecting door is opened and a hydraulic cylinder and piston ejects the compacted mass from the refuse compactor. The control arrangement coordinates the timing and sequence of operations of a compacting cycle during which a bale is formed and transferred from the compacting machine.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
152 words
A refuse compactor comprising in combination, a housing; compacting means in said housing for compacting a predetermined amount of refuse into a compacted mass by applying pressure to said refuse; pressure-sensing means for sensing said pressure and emitting a signal when said pressure exceeds a predetermined magnitude; means connected to said pressure-sensing means and operatively coupled to said compacting means for ceasing operation of said compacting means after said pressure exceeds said predetermined magnitude; ejecting means for ejecting said compacted mass from said compactor after attainment of said predetermined pressure magnitude and cessation of operation of said compacting means; and timing means connected to said pressure-sensing means and inhibiting transmission of said signal from said pressure-sensing means until the expiration of a predetermined time interval after said pressure exceeds said predetermined magnitude so that said compacting means is operative during said time interval, said timing means allowing breakage of normally noncompactible material.
Claim 2
Dependent Claim
152 words
A refuse compactor comprising in combination, a housing; compacting means in said housing for compacting a predetermined amount of refuse into a compacted mass by applying pressure to said refuse; pressure-sensing means for sensing said pressure and emitting a signal when said pressure exceeds a predetermined magnitude; means connected to said pressure-sensing means and operatively coupled to said compacting means for ceasing operation of said compacting means after said pressure exceeds said predetermined magnitude; ejecting means for ejecting said compacted mass from said compactor after attainment of said predetermined pressure magnitude and cessation of operation of said compacting means; and timing means connected to said pressure-sensing means and inhibiting transmission of said signal from said pressure-sensing means until the expiration of a predetermined time interval after said pressure exceeds said predetermined magnitude so that said compacting means is operative during said time interval, said timing means allowing breakage of normally noncompactible material.
Claim 3
Dependent Claim
57 words
The refuse compactor as defined in claim 1, including accumulating means for accumulating refuse within said compactor prior to compacting through said compacting means; accumulator-sensing means for sensing when refuse is transferred to said accumulating means; and disinfecting means actuated by said accumulator-sensing means For applying disinfectant to said refuse prior to compacting through said compacting means.
Claim 4
Dependent Claim
32 words
The refuse compactor as defined in claim 2 including timing means actuated by said accumulator-sensing means for determining when said accumulating means is filled with a predetermined amount of refuse for compacting.
Claim 5
Dependent Claim
34 words
The refuse compactor as defined in claim 2 including auxiliary timing means for timing the duration of operation of said compacting means to assure that said accumulator means will be cleared of accumulated refuse.
Claim 6
Dependent Claim
27 words
The refuse compactor as defined in claim 4 wherein said duration of operation of said compacting means is sufficient to clear said accumulating means of accumulated refuse.
Claim 7
Dependent Claim
19 words
The refuse compactor as defined in claim 2 wherein said accumulator-sensing means comprises photosensitive means within said accumulating means.
Claim 8
Dependent Claim
61 words
The refuse compactor as defined in claim 1 including protective means connected to said compacting means for transferring said compactor to an inoperative state when said pressure exceeds a predetermined safe pressure limit and when access doors of said compactor are open, said protective means also including means for rendering said compactor inoperative when said pressure is below a predetermined level.
Claim 9
Dependent Claim
56 words
The refuse compactor as defined in claim 1 including ejecting door means through which said compacted mass is ejected from said compactor, said ejecting door means covering an opening of said compactor during operation of said compacting means and being actuated by said pressure-sensing means for uncovering said opening prior to ejecting said compacted mass therethrough.
Claim 10
Dependent Claim
34 words
The refuse compactor as defined in claim 8 including means for sensing when said ejection door has uncovered said opening and actuating thereafter said ejecting means for ejecting said compacted mass from said compactor.
Claim 11
Dependent Claim
37 words
The refuse compactor as defined in claim 9 including means for sensing when said compacted mass has been ejected through said opening and actuating said ejecting door for covering said opening after ejection of said compacted mass.
Claim 12
Dependent Claim
31 words
The refuse compactor as defined in claim 10, including means for advancing a conveyor to replace a filled refuse container with an empty one at the completion of said ejecting means.
Claim 13
Dependent Claim
22 words
The refuse compactor as defined in claim 1 wherein said compacting means and said ejecting means comprise hydraulically operated cylinders and pistons.
Claim 14
Dependent Claim
20 words
The refuse compactor as defined in claim 12 wherein said pressure-sensing means measures the hydraulic pressure of said compacting means.
Claim 15
Independent Claim
193 words
A method for compacting refuse materials comprising the steps of: accumulating a predetermined quantity of uncompacted refuse which when compacted constitutes a compacted mass of refuse of predetermined density and volume; applying pressure to said predetermined accumulated quantity of uncompacted refuse for compacting said refuse into predetermined shape within the confines of a predetermined space; removing said pressure from said refuse after the intensity of the applied pressure attains a predetermined level, said refuse being compacted into said compacted mass when the applied pressure has attained said level; timing the interval during which said pressure exceeds said level and continuing applying said pressure to said predetermined quantity of uncompacted refuse when said interval is below a predetermined magnitude for allowing breakage of normally noncompactible material, the application of said pressure being discontinued after said predetermined magnitude of said time interval has expired; opening said spaced to expose said compacted mass; ejecting said compacted mass from the confinements of said space; closing said space for compacting a subsequent predetermined quantity of refuse; and advancing a conveyor system to replace a filled refuse container with an empty one at the completion of said ejection cycle.
Claim 16
Independent Claim
193 words
A method for compacting refuse materials comprising the steps of: accumulating a predetermined quantity of uncompacted refuse which when compacted constitutes a compacted mass of refuse of predetermined density and volume; applying pressure to said predetermined accumulated quantity of uncompacted refuse for compacting said refuse into predetermined shape within the confines of a predetermined space; removing said pressure from said refuse after the intensity of the applied pressure attains a predetermined level, said refuse being compacted into said compacted mass when the applied pressure has attained said level; timing the interval during which said pressure exceeds said level and continuing applying said pressure to said predetermined quantity of uncompacted refuse when said interval is below a predetermined magnitude for allowing breakage of normally noncompactible material, the application of said pressure being discontinued after said predetermined magnitude of said time interval has expired; opening said spaced to expose said compacted mass; ejecting said compacted mass from the confinements of said space; closing said space for compacting a subsequent predetermined quantity of refuse; and advancing a conveyor system to replace a filled refuse container with an empty one at the completion of said ejection cycle.
