Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a lantern and fuel system and method and more particularly pertains to allowing a user to safely and conveniently use a liquid fuel to provide heat and light.




2. Description of the Prior Art




The use of lantern and fuel systems of known designs and configurations is known in the prior art. More specifically, lantern and fuel systems of known designs and configurations previously devised and utilized for the purpose of providing heat and light are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.




By way of example, U.S. Pat. No. 3,773,458 to Spotts discloses a portable convertible mantle-lantern, camp stove. U.S. Pat. No. 3,804,075 to Rummel discloses attachments for lanterns. U.S. Pat. No. 4,029,079 to Elder discloses a lantern stove device attachment. U.S. Pat. No. 4,372,198 discloses a lantern hot plate. U.S. Pat. No. 4,091,795 discloses a cooking adapter. U.S. Pat. No. 4,954,075 discloses a lantern head for backpacker's stove. U.S. Pat. No. 5,113,843 to Henry et al. discloses a combustion device for stoves and fireplaces. Lastly, U.S. Pat. No. 6,439,223 issued Aug. 27, 2002, to Draper et al. discloses a lantern system.




While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a lantern and fuel system and method that allows allowing a user to safely and conveniently use a liquid fuel to provide heat and light.




In this respect, the lantern and fuel system and method according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of allowing a user to safely and conveniently use a liquid fuel to provide heat and light.




Therefore, it can be appreciated that there exists a continuing need for a new and improved lantern and fuel system and method to safely and conveniently use a liquid fuel to provide heat and light. In this regard, the present invention substantially fulfills this need.

a vaporizer shaft having an upper shaft and a lower shaft and a shaft connector with each shaft sized to fit loosely within the tubular body of the valve with the lower shaft threadedly coupling with the shaft connector and the vaporizer lower subassembly check valve and operating the valve as the handle shaft is turned, and the upper shaft threadedly coupled with the connector and the jet needle so that rotation of the knob performs one of the two operations which include the opening of the lower check valve to allow the passage of fuel and the engagement of the needle into the aperture of the nipple, a quantity of steel wool wrapped around the vaporizer shaft; a J-shaped mixing tube having an internal diameter and an external diameter and a wall thickness there between, the tube having an internally coupled wire mesh and an internal rotatably movable baffle plate with an associated rotation shaft, the tube having a longer portion and a shorter portion, the shorter portion of the mixing tube having a baffle plate aperture with the rotatable baffle located within the internal diameter of the tube with the rotation shaft protruding through the plate aperture, the shorter portion coupling with the lantern top cap between about ¾ and 2 inches from the jet aperture of the vaporizer forming a mixing chamber, the longer portion protruding downward toward the center of the glass chimney; a mantel coupled to the short portion of the mixing tube and suspended within the glass chimney; and a quantity of liquid methanol to be used as a fuel.
  • 2. A lantern and fuel system, comprising in combination:a fuel tank; a pressure gauge subassembly coupled to the fuel tank; a pump subassembly coupled to the tank; a lower skirt coupled to the tank; a lower skirt cap coupled to the tank; an ignition bowl having an up-pipe coupled to the tank; a safety cover having a Z-shaped upward projection coupled to the lower skirt; an upper skirt coupled to the glass chimney; a heat resistant glass chimney coupled to the lower skirt and the upper skirt; a lantern top cap having a mixing chamber, coupled to the upper skirt; a plurality of connecting rods to firmly hold and contain the glass chimney there between the upper skirt and the lower skirt; a vaporizer having two warming coils and a nipple; a vaporizer shaft; a quantity of steel wool wrapped around the vaporizer shaft; a J-shaped mixing tube having a wire mesh and a baffle plate coupled to the lantern top cap; a mantel coupled to the mixing tube; and a quantity of liquid methanol to be used as a fuel.
  • 3. A lantern and fuel system as described in claim 2 wherein the liquid fuel is methanol.
  • 4. A lantern and fuel system as described in claim 2 wherein the fuel tank has a check valve which allows ambient pressurization of the fuel tank.
  • 5. A lantern and fuel system as described in claim 2 wherein the lantern and fuel system further comprises a bicycle hand pump fitting in place of the hand pump to allow a user to utilize a bicycle hand pump to pressurize the system.
  • 6. A lantern and fuel system as described in claim 2 wherein a carbon dioxide cartridge is utilized to pressurize the fuel tank.
  • 7. A lantern and fuel system as described in claim 2 wherein the top of the lantern is a cooking surface being coupled to the handle studs.
  • 8. A lantern and fuel system as described in claim 2 wherein the steel wool wrapped around the shaft is stainless steel wool.
  • 9. A lantern and fuel system as described in claim 2 wherein the wire mesh in the J-shaped mixing tube is stainless steel mesh.
