Abstract
Abstract An apparatus for both improving the heat distribution throughout a room from a portable kerosene heater and for collecting undesirable emissions resulting from the burning of the kerosene, includes a base adapted to be mounted on the top of the heater, the base supporting a vertically extending shaft on which is mounted a heat-driven fan formed of either paper or metal, and a disposable disk mounted a spaced distance above the fan on the same shaft, the disk serving as a collector for the undesirable emissions. When the device is placed on an operating kerosene heater, the rising hot air and gases from the heater cause the fan to rotate, which in turn causes emissions from the burning fuel to move upwardly in a more or less cylindrical path. As the products of combustion move upwardly, certain emissions therein such as soot, oily vapors, etc. deposit or condense onto the surface of the spinner and disposable disk.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
143 words
A device for collecting emissions from a kerosene heater or the like, and for improving the distribution of heated air from such a heater, comprising base means for locating and supporting said device above the heater, and including a vertical shaft; spinner means mounted on said shaft for rotation about the axis of said shaft relative to said base means, said spinner means being capable of being rotatably driven about the axis of said shaft by hot air rising from the heater, for causing hot air and combustion gases from the heater to move upwardly in a generally cylindrical column, said spinner means comprising a plurality of fan blades; and at least one heat-resistant, rotatable, pollutant absorber means mounted on said shaft and spaced above said spinner means for rotation therewith, for collecting polluting emissions from the gases of combustion of the heater.
Claim 2
Independent Claim
143 words
A device for collecting emissions from a kerosene heater or the like, and for improving the distribution of heated air from such a heater, comprising base means for locating and supporting said device above the heater, and including a vertical shaft; spinner means mounted on said shaft for rotation about the axis of said shaft relative to said base means, said spinner means being capable of being rotatably driven about the axis of said shaft by hot air rising from the heater, for causing hot air and combustion gases from the heater to move upwardly in a generally cylindrical column, said spinner means comprising a plurality of fan blades; and at least one heat-resistant, rotatable, pollutant absorber means mounted on said shaft and spaced above said spinner means for rotation therewith, for collecting polluting emissions from the gases of combustion of the heater.
