ABSTRACT:
A liquid-fueled lamp comprising a liquid-impervious container, which is preferably a light-weight steel can of the type used to store foods, etc. A relatively small opening is provided in the top of the can, and a tube or some other structural member extends through the opening. The tube is preferably rigidly secured to the container, as by welding or brazing. A metal tube having a 1/4 inch diameter is suitable. A flame-positioning means, such as a "plug" of asbestos fibers, is mounted in the top of the tube. A wick for transferring fuel from within the container to the flame-positioning means is also provided. Preferably, the wick is made of a narrow piece of double-knit polyester material. The wick and the plug of asbestos fibers are mechanically held together by the tube, so that fuel drawn upward by the wick will saturate the asbestos plug. Typically, the wick will furnish more fuel to the asbestos plug than will be consumed by a flame. Hence, a fuel-drainage means is desirable for permitting the drainage of excess fuel back into the container. The fuel-drainage means may consist of a structural trap surrounding the tube, with an aperture located in the top of the container and within the structural trap. The preferred fuel for such a lamp is mineral oil, which heretofore has been primarily used as a laxative and lubricant, and as a carrier for cosmetics and insecticides, etc. Such oil as meets National Formulary (NF) or U.S. Pharmacopia (USP) specifications for mineral oil will burn with essentially no odor. Technical grade mineral oil will also burn in the lamp described herein, but it has a faint odor that might be objectionable to some persons. The lamp is particularly safe when it is fueled with mineral oil, because--unlike kerosene and other fuel oils--mineral oil is rather hard to burn.
