Abstract
A liquid fuel burning device includes a first fuel reservoir adapted for holding a supply of fuel, a wick system adapted to cooperate with the first reservoir to draw fuel therefrom for combustion, a second fuel reservoir and a fuel feed tube communicating between the first fuel reservoir and the second fuel reservoir. The first reservoir can be closed to form a substantially air tight seal such that as fuel is consumed from the first reservoir, a partial vacuum is created within the first reservoir which automatically draws further fuel through the feed tube from the second fuel reservoir, thereby maintaining a constant fuel supply in the first reservoir.
Claims13
A liquid fuel burning device comprising:
- a first reservoir adapted for holding a supply of fuel and being closable to form a substantially air-tight seal;
- a wick system adapted to cooperate with said first reservoir to withdraw fuel therefrom for combustion;
- a second reservoir for containing fuel, said second reservoir being in the shape of an elongate cylinder which cooperates with said first reservoir to form an integrated unit;
- and
- a feed tube communicating between the first reservoir and the second reservoir, the feed tube having an opening at or near a bottom portion of said second reservoir;
- wherein withdrawal of fuel from said first reservoir for combustion creates a partial vacuum therein which automatically draws further fuel through said feed tube from said second reservoir, thereby maintaining a constant fuel supply within said first reservoir.
A liquid fuel burning device comprising:
- a first reservoir adapted for holding a supply of fuel and being closable to form a substantially air-tight seal;
- a wick system adapted to cooperate with said first reservoir to withdraw fuel therefrom for combustion;
- a second reservoir remote from said first reservoir for containing fuel;
- a feed tube communicating between the first reservoir and the second reservoir;
- wherein withdrawal of fuel from said first reservoir for combustion creates a partial vacuum therein which automatically draws further fuel through said feed tube from said second reservoir, thereby maintaining a constant fuel supply within said first reservoir.
A liquid fuel burning device comprising:
- a first reservoir adapted for holding a supply of fuel and being closable to form a substantially air-tight seal;
- a plurality of wick systems, each said wick system comprising a cap adapted to sealably fit to an opening in a top portion of said pod, a wick tube traversing said cap and a wick adapted for snug fit through said wick tube, each said wick system adapted to cooperate with said first reservoir to withdraw fuel therefrom for combustion;
- a second reservoir for containing fuel;
- and
- a feed tube communicating between the first reservoir and the second reservoir;
- wherein withdrawal of fuel from said first reservoir for combustion creates a partial vacuum therein which automatically draws further fuel through said feed tube from said second reservoir, thereby maintaining a constant fuel supply within said first reservoir.
A liquid fuel burning device comprising:
- a plurality of first reservoirs adapted for holding a supply of fuel and being closable to form a substantially air-tight tight seal;
- a wick system associated with each of said first reservoirs adapted to cooperate with said first reservoir to withdraw fuel therefrom for combustion;
- at least one second reservoir for containing fuel;
- and
- a plurality of feed tubes, each of said feed tubes communicating between one of said first reservoirs and said at least one second reservoir;
- wherein withdrawal of fuel from said first reservoirs for combustion creates a partial vacuum therein which automatically draws further fuel through said feed tube from said at least one second reservoir, thereby maintaining a constant fuel supply within said first reservoirs.
