Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
55 words
An incinerator comprising a centrally disposed main combustion chamber, an afterburner chamber encircling the main combustion chamber, burner means in said after-burner chamber, a wall separating said chambers, and at least two spaced port means in said wall for circulation of gases therethrough between said chambers, and an exhaust flue connected with said afterburner chamber.
Claim 2
Dependent Claim
55 words
An incinerator comprising a centrally disposed main combustion chamber, an afterburner chamber encircling the main combustion chamber, burner means in said after-burner chamber, a wall separating said chambers, and at least two spaced port means in said wall for circulation of gases therethrough between said chambers, and an exhaust flue connected with said afterburner chamber.
Claim 3
Dependent Claim
26 words
An incinerator as set forth in claim 1 having pump means operatively connected with one chamber for circulating gases between said chambers through said port means.
Claim 4
Dependent Claim
40 words
An incinerator as set forth in claim 2 wherein said pump means has a portion located in said main combustion chamber adjacent one of said port means for introducing air under pressure through said adjacent port into said afterburner chamber.
Claim 5
Dependent Claim
53 words
An incinerator as set forth in claim 3 wherein a venturi is disposed within said port means, and said portion of the pump means comprises a nozzle within and smaller than said port means whereby air passing from said nozzle into the venturi will draw with it gases from the main combustion chamber.
Claim 6
Dependent Claim
85 words
An incinerator comprising a trash chamber, an afterburner chamber encircling said trash chamber, a wall between the trash chamber and afterburner chamber, burner means within the afterburner chamber, a first port in said wall adjacent said burner, and pump means in said trash chamber adjacent said port for introducing air under pressure through said port into the afterburner, and a second port in said wall spaced from said first port for permitting flow of air and gases from the afterburner chamber into the trash chamber.
Claim 7
Dependent Claim
85 words
An incinerator comprising a trash chamber, an afterburner chamber encircling said trash chamber, a wall between the trash chamber and afterburner chamber, burner means within the afterburner chamber, a first port in said wall adjacent said burner, and pump means in said trash chamber adjacent said port for introducing air under pressure through said port into the afterburner, and a second port in said wall spaced from said first port for permitting flow of air and gases from the afterburner chamber into the trash chamber.
Claim 8
Dependent Claim
17 words
An incinerator as set forth in claim 5 having an exhaust flue connected with said afterburner chamber.
Claim 9
Dependent Claim
42 words
An incinerator as set forth in claim 5 having a second burner in said afterburner chamber, a third port adjacent said second burner, a fourth port spaced from said third port, and second pump means in said afterburner adjacent said third port.
Claim 10
Dependent Claim
49 words
An incinerator as set forth in claim 5 wherein baffles are located in said afterburner chamber adjacent each port, said baffles being disposed to intercept only a portion of the air-gas mixture passing through the afterburner chamber for deflecting said portion back through the ports into the trash chamber.
Claim 11
Dependent Claim
64 words
An incinerator comprising a central combustion chamber, an encircling afterburner chamber separated from said combustion chamber by an annular wall, burner means in said afterburner chamber for heating gases therein to combustion temperatures, at least two spaced port means in said wall, and recirculation means for circulating air-gas mixtures back and forth between the chambers, and an exhaust flue connected with said afterburner chamber.
Claim 12
Dependent Claim
64 words
An incinerator comprising a central combustion chamber, an encircling afterburner chamber separated from said combustion chamber by an annular wall, burner means in said afterburner chamber for heating gases therein to combustion temperatures, at least two spaced port means in said wall, and recirculation means for circulating air-gas mixtures back and forth between the chambers, and an exhaust flue connected with said afterburner chamber.
Claim 13
Dependent Claim
57 words
An incinerator as set forth in claim 9 wherein said recirculation means comprises pump means adjacent one of said port means for directing air and gas from the central combustion chamber into the afterburner chamber, and deflector means for guiding circulation of said air and gas back into the central combustion chamber through a different port means.
Claim 14
Dependent Claim
45 words
An incinerator as set forth in claim 10 wherein said deflector means are located in said afterburner chamber adjacent said additIonal port means for intercepting and deflecting into the central combustion chamber a portion only of the air and gas flowing through the afterburner chamber.
