Abstract
A floating illuminating device adapted to float upon a body of combustible oil. A wick supported on a wick-holder draws oil by capillary action and may be ignited to provide illumination. The wick-holder is formed with a central depending generally frusto-conical well portion surrounded by elongate buoyancy imparting cavities which are spaced a substantial distance from the wick so that they do not suffer heat distortion. Improved channel means allow the oil to flow into the well.
