A lantern comprising a tank, a chimney, an ignition bowl, and a chimney tube. There is also a mixing subassembly, a fuel line, a nozzle and a chimney cap. There is an igniter subassembly, an outflow subassembly and a pump. The igniter subassembly is angled to the right, and inward, providing more efficient heating of the outflow subassembly upper heating tube and loop. A outflow tube, which carries the fuel, has two external dimensions, which provides for more efficient fuel heating. |

1. A lantern comprising:
a tank having a generally hemispherical upper outside wall and a lower base, the upper outside wall of the tank having a filling spout portion and a pump portion and an outflow hole portion and an igniter aperture portion, the filling spout portion of the tank being formed by a generally rounded raised area of the outside wall of the tank with a tank filling spout coupled thereto; a chimney having lower skirt with an upper portion and a lower portion, the chimney having an upper sleeve and the chimney having a plurality of connecting tubes, with the chimney coupled to the tank; an ignition bowl having a generally U-shaped configuration with a recess therein; a chimney tube having an upper end and a lower end with a length therebetween, the chimney tube being coupled to the chimney; a mixing subassembly having a housing and a fuel flow tube, the mixing subassembly housing having a lower end and an upper end, the mixing subassembly coupling with the upper sleeve of the chimney; a fuel line having a hollow J-shaped tubular configuration with a short outer portion and a long inner portion, the short outer portion of the fuel line having an end, the fuel line being coupled to the mixing subassembly; a nozzle having a first end and a second end with a length therebetween, the nozzle being coupled to the fuel line; a chimney cap having a closed upper end and an open lower end; an igniter subassembly coupled to the igniter aperture portion of the tank, the igniter subassembly having a lower feed tube and an upper burning tube, the igniter subassembly lower feed tube having a lower end with an opening therein and an upper end with an opening therein with a continuous passage therethrough from the lower end of the igniter subassembly feed tube to the upper end of the igniter subassembly feed tube, the upper burning tube of the igniter subassembly having a lower end and an upper end and an intermediate section therebetween; an outflow subassembly coupled to the outflow portion of the tank, the outflow subassembly having an outflow fuel feed tube and a control valve subassembly and an upper heating tube, the fuel feed tube of the outflow subassembly having a passageway therethrough, the fuel feed tube of the outflow subassembly having an upper end and a lower end; and a pump comprising the stub and a shaft and a grip and a piston and the end cap. |
