Abstract
Abstract Combustion gas channelled to flow alongside a surface of an open burner, such as over the usually upright catalytic bed of a space heater, or a generally horizontal stove cooking top or pot bottom overlying the open burner, is segregated by an aperture in the path of flow of the combustion gas, so that the gas flows through such aperture, instead of being dissipated into a room space and mixed with the ambient gases of the space. The effluent combustion gas thus sequestered is withdrawn by suction through a discharge duct. The opening through such aperture or discharge duct can be regulated by a shutter or damper, which can be adjusted by temperature-responsive thermostatic means, responsive to the temperature of combustion gas flowing through the segregating aperture or discharge duct, to enlarge the opening as the temperature rises and to restrict the opening as the temperature decreases.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
Apparatus for sequEstering combustion gas from a burner in a living space, comprising a generally horizontal surface beneath which the burner occurs, means supplying combustible gas for burning for flow of substantially smokeless combustion gas closely adjacent to said surface, a tubular ring remote from and encircling said combustible gas-supplying means having an apertured inner periphery located adjacent to said surface for receiving combustion gas, said surface guiding the flow of the combustion gas along said surface toward said apertured inner ring periphery, and effluent combustion gas confining means leading from said tubular ring for flow of effluent combustion gas therethrough to a location separated from the living space in which the burner is located, said tubular ring having an apertured outer periphery for flow therethrough of air to be mixed in said ring with combustion gas entering said ring through its apertured inner periphery.
Claim 2
Dependent Claim

Apparatus for sequEstering combustion gas from a burner in a living space, comprising a generally horizontal surface beneath which the burner occurs, means supplying combustible gas for burning for flow of substantially smokeless combustion gas closely adjacent to said surface, a tubular ring remote from and encircling said combustible gas-supplying means having an apertured inner periphery located adjacent to said surface for receiving combustion gas, said surface guiding the flow of the combustion gas along said surface toward said apertured inner ring periphery, and effluent combustion gas confining means leading from said tubular ring for flow of effluent combustion gas therethrough to a location separated from the living space in which the burner is located, said tubular ring having an apertured outer periphery for flow therethrough of air to be mixed in said ring with combustion gas entering said ring through its apertured inner periphery.
Claim 3
Dependent Claim
134 words
Apparatus for sequestering combustion gas from a burner in a living space, comprising a generally horizontal surface beneath which the burning occurs, means supplying combustible gas for burning for flow of substantially smokeless combustion gas closely adjacent to said surface, an upper tubular ring remote from and encircling said combustible gas supplying means and having an apertured inner periphery located closely adjacent to said surface for receiving combustion gas, said surface guiding combustion gas along said surface towards said apertured inner ring periphery, a lower tubular ring, and tubular posts spaced circumferentially of said rings, connected between said upper tubular ring and said lower tubular ring and affording communication therebetween, said posts definings openings therebetween for communication between the space outward of said tubular rings and the burner encircled by said upper tubular ring.
