the aperture 13 permitting the heated air to rise from the chimney 6 and come into con- tact with the bottom of the pot. I regard it as of importance that the device is supported from the lower surface of the top member 2, since, by this construction, the center of gravity of the device is brought down to as low a point as possible. It is a well known fact that but a small portion of the oil consumed by ordinary Iamps actually. goes to furnish light, the! major portion being dissipated in the form of heat, and my invention provides a simple and inexpensive means whereby the heat gen- erated by a lamp may be employed to aid in heating a room, or to cook alight meal. Having thus described my invention, what I claim as new, and desire to protect, by Let- ters Patent, is: A heating drum comprising a bottom1
member and a top member each conveying from the other, the bottom member being apertured to receive a lamp chimney, and the top member being provided on its un- der surface with resilient chimney-engaging 25 prongs; a peripheral strip uniting the top and bottom members within their periphery and being provided with a draft aperture; a circular damper arranged to slide upon the peripheral strip between the top and bottom so members and having an aperture arranged to register with the draft aperture in the strip. In testimony that I claim the foregoing as my own, I have hereto affixed-my signa- ture in the presence of two witnesses. JAMES CLOYD DREW. Witnesses: J. D. FOURAKER, E. P. BRYAN.
