Abstract

Abstract A trash compacting apparatus including a first chamber, a second chamber communicating with a top opening in the first chamber, a third chamber communicating with a side opening in the first chamber, a carriage assembly movable horizontally through the first chamber between first and second positions, a compaction platen for compressing trash delivered to the second chamber against the top of the carriage assembly when the carriage assembly is in the first position, and a scraping element arranged at the intersection of the first and second chambers for scraping trash off the top of the carriage into the first chamber when the carriage assembly moves from the first position to the second position, whereby trash in the first chamber is compacted into the third chamber when the carriage assembly moves from the second position to the first position.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 254 words
A trash compacting apparatus comprising: first means for defining a first chamber having a top opening and a side opening; second means, coupled to said first means, for defining a second chamber located above and directly communicating with said first chamber through said top opening; third means, coupled to said first means, for defining a third chamber located on one side of and directly communicating with said first chamber through said side opening; a carriage assembly longitudinally movable through said first chamber between a first position wherein a first portion of said carriage assembly fills said top opening and a second portion of said carriage assembly fills said side opening, and a second position wherein said first and second portions are spaced from said openings; chute means, coupled to said second chamber, for delivering trash into said second chamber; compaction means, located in said second chamber, for compressing trash against said first portion of said carriage assembly when said carriage assembly is in said first position; power means for moving said carriage assembly between said first and second positions; and scraping means, located adjacent said top opening and in contacting relationship with said first portion, for scraping said first portion of trash as said first portion is moved from said first position to said second position to thereby cause the trash to fall into said first chamber; whereby movement of said carriage assembly from said second position causes the trash in said first chamber to be transferred to and compacted in said third chamber.
Claim 2
Dependent Claim 254 words
A trash compacting apparatus comprising: first means for defining a first chamber having a top opening and a side opening; second means, coupled to said first means, for defining a second chamber located above and directly communicating with said first chamber through said top opening; third means, coupled to said first means, for defining a third chamber located on one side of and directly communicating with said first chamber through said side opening; a carriage assembly longitudinally movable through said first chamber between a first position wherein a first portion of said carriage assembly fills said top opening and a second portion of said carriage assembly fills said side opening, and a second position wherein said first and second portions are spaced from said openings; chute means, coupled to said second chamber, for delivering trash into said second chamber; compaction means, located in said second chamber, for compressing trash against said first portion of said carriage assembly when said carriage assembly is in said first position; power means for moving said carriage assembly between said first and second positions; and scraping means, located adjacent said top opening and in contacting relationship with said first portion, for scraping said first portion of trash as said first portion is moved from said first position to said second position to thereby cause the trash to fall into said first chamber; whereby movement of said carriage assembly from said second position causes the trash in said first chamber to be transferred to and compacted in said third chamber.
Claim 3
Dependent Claim 27 words
An apparatus according to claim 1, further including sensing means, located in said chute means, for actuating said compaction means when trash passes through said chute means.
Claim 4
Dependent Claim 20 words
An apparatus according to claim 1, further including control means, coupled to said compaction means, for actuating said power means.
Claim 5
Dependent Claim 25 words
An apparatus according to claim 1, wherein said carriage assembly includes ejection means, coupled to said power means, for ejecting trash from said third chamber.
Claim 6
Dependent Claim 59 words
An apparatus according to claim 4, wherein said third chamber has an inlet and an outlet, said inlet coinciding with said side opening of said first chamber and said ejection means includes an ejection member, and means for moving said ejection member horizontally and independently of said carriage assembly between said inlet and said outlet of said third chamber.
Claim 7
Dependent Claim 45 words
An apparatus according to claim 1, wherein said power means includes screw drive means rotatably mounted adjacent said first and third chambers, and connection means, coupled to said carriage assembly and said screw drive means, for coupling said carriage assembly to said screw drive means.
Claim 8
Dependent Claim 17 words
An apparatus according to claim 6, wherein said third chamber further includes means for closing said outlet.
Claim 9
Dependent Claim 26 words
An apparatus according to claim 1, wherein said means for scraping is formed by the intersection of portions of said chute means and said first chamber.
Claim 10
Dependent Claim 73 words
An apparatus according to claim 1, wherein said carriage assembly comprises a bottom member supported on and slidable along the bottom of said first chamber; and a planar top member supported above said bottom member so that the plane containing the top of said top member is coincident with the plane containing the top opening of said first chamber, said top of said top member forming said first portion of said carriage assEmbly.
Claim 11
Dependent Claim 42 words
An apparatus according to claim 1, wherein said chute means comprises a chute having a sloping bottom wall, said sloping bottom wall intersecting the top of said first chamber and ending in the plane containing said top opening of said first chamber.
Claim 12
Dependent Claim 16 words
An apparatus according to claim 1, wherein said first portion of said carriage assembly is flat.
