Abstract
Abstract A casing is supported on legs and a canister of methyl hydrate or the like soaked in an absorbent material, is situated under the casing and within the legs and acts as a source of heat. An aperture is formed in the base of said casing and the upper side of the canister is flush with the base and under the aperture. An aperture flame and heat propagating plate is situated within the casing just above the base and a grill is situated in the casing above the plate. The grill has drain troughs and spaces between the drain troughs for some fat to drip onto the plate during cooking. When lit, the plate not only radiates heat to the grill, but also reflects heat back to the canister giving a gassing effect which produces extremely high heat in a relatively short time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
199 words
A cooking unit such as a barbecue and the like comprising in combination a casing having an apertured base, a pair of sides and a rear panel and means to support said casing, a cover for said casing closing off the upper and front side of said casing when closed, a source of heat under said casing and aligned with the aperture in said base, a heat propagating plate, said plate within said casing and spanning same, a cooking grill in said casing above said heat propagating plate, said grill being apertured whereby fat may be dripped through said grill onto said heat propagating plate, said heat propagating plate being apertured adjacent the perimetrical edges thereof whereby flames may pass through said plate and impinge upon the underside of said grill, said heat propagating plate being supported upon the underside of said grill, said source of heat including a container, absorbent means in said container, and a volatile heating fluid in said container, said container being situated below said heat propagating plate and in close proximity therewith whereby said heat propagating plate reflects back heat directly onto said container thereby increasing the rate of evaporation of said volatile fluid.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
26 words
The device according to claim 1 which includes means to control the position of said source of heat relative to said heat propagating plate, within limits.
Claim 4
Dependent Claim
26 words
The device according to claim 2 in which said source of heat is spaced from the perimetrical edges of said base that define the aperture therein.
Claim 5
Dependent Claim
26 words
The device according to claim 2 in which said source of heat is spaced from the perimetrical edges of said base that define the aperture therein.
