Patent ID: 8920161

Claim:
Apparatus for containing a heat source ( 36 ) in a chamber ( 16 ) having a chimney-section ( 22 ), the apparatus having a gas inlet opening ( 24 , 26 , 30 ) and a gas outlet opening ( 32 ), the gas outlet opening ( 32 ) being formed in the chimney-section ( 22 ), wherein the gas inlet opening ( 24 , 26 , 30 ) and the heat source are located in a lower area ( 12 , 20 ′) of the chamber ( 16 ) and the gas outlet opening ( 32 ) is located in an upper region ( 14 ) of the chamber ( 16 ) so that, when a heat source is placed in the chamber ( 16 ), an ascending gas flow may be generated in the chamber ( 16 ), wherein inflowing gas flows into the lower area ( 12 , 20 ′) of the chamber ( 16 ) and then is drawn upwardly by a draw of the ascending gas flow and then though the gas outlet opening ( 32 ), wherein further, the apparatus includes a subassembly ( 27 ) includes an air flow guide ( 140 ), clips ( 142 ), a cover ( 304 ) with a centering hole ( 305 ) and a liner ( 136 ), the cover ( 304 ) connected to the subassembly ( 27 ) via the clips ( 142 ), the liner ( 136 ) having a lower end adapted to contain a container ( 302 ) enclosing a combustible liquid and having a wick ( 307 ), wherein the centering hole ( 305 ) is adapted to allow the wick ( 307 ) to pass therethrough, and wherein the chimney-section ( 22 ) is attached to the subassembly ( 27 ) so that lateral tilting of the chimney-section ( 22 ) causes motion of the subassembly ( 27 ) relative to the wick ( 307 ).
