Abstract
Abstract A portable and nestable hibachi type stove having two housings defining a first chamber and a larger second chamber, respectively, each of the housings having a tapered wall configuration extending between a larger open end and a smaller open end. A grate, a rack and one or more draft openings are provided in each housing, with the smaller ends of each housing being of like size and configuration for mating with one another. Either housing can serve as an upper firebox chamber or a lower preignition chamber to allow selection of different size cooking surfaces, and the entire stove structure is demountable and nestable for ease of storage and transportation.
