  • Patent number: 6783356
    Abstract: A candle structure comprises a fan, wherein the heated air generated by a candle may propel the fan. The candle is housed in a container having a bottom wall and a side wall. The side wall is formed with vents located above the candle so that adequate air needed to permit the candle to combust can be drawn through the vent, thereby to enhance propulsion of the fan. The fan serves to impart a new functional and aesthetically pleasing characteristic to the basic candle structure by distributing the heat and the scent generated by the candle, while concurrently rotating decorative elements.

  • Patent number: 4827382
    Abstract: A multiple lamp shade system for a light bulb in which one of the lamp shades is rotatable and powered by heat given off by the light bulb. A multiply apertured base is held against a light bulb socket by surface contact with the light bulb. A light transmissible stationary inner lamp shade is attached at one end to the base. The other end of the inner lamp shade is partially occluded by a thrust plate on which is located an axially positioned upstanding pointed member. A peripheral annular gap is provided between the wall of the inner lamp shade and the thrust plate. A light transmissible rotatable lamp shade is co-axially mounted over the inner lamp shade and is bearingly supported via a bearing plate, at one end on the upstanding pointed member. A plurality of air vent chutes are annularly arranged adjacent the bearing plate. In operation, the light bulb heats the air within the lamp shades, causing an air convection current which upwells within the lamp shades.
