Portable combustible fuel automatic drip coffee making apparatuses use combustible fuels such as propane, butane, white gasoline, and kerosene to heat water which can be alternatively used to make drip coffee, or for other requirements calling for heated water, depending on the selected position of a switching valve. The portability of these devices is self contained and hand transportable. The inventive units are designed to be user maintained with easily cleanable or replaceable parts, as well as designed for manufacturing. These units are configured b...

1. A portable automatic drip coffee maker heated by combustible fuel, comprising:a housing containing a fuel stream and a water stream; the fuel stream including: a burner disposed in said housing; a fuel conduit having a first end attached to said burner and a second end adapted for attachment to a fuel tank containing a combustible fuel; a flow regulating valve disposed in said fuel conduit between said burner and the fuel tank for regulating the flow of fuel to said burner; and ignition means for initiating combustion of fuel in said burner; the water stream including: a water reservoir; a water heating coil disposed above said burner; a drip dispenser disposed in said housing above said burner and said heating coil; a water conduit connecting said reservoir, said water heating coil, and said drip dispenser; a valve disposed in said conduit, said valve having a first position for directing water to flow from said water heating coil to said drip dispenser, and a second position directing water to flow from said water heating coil back to said water reservoir; a support brace holding together said burner and said water heating coil as an integral burner-heater coil assembly, the support brace including three arms extending radially outward from a central opening, and the distal end of each arm including a removable replaceable connector that can be removed to permit the separation of the water coil from the burner-heater coil assembly; a carafe disposed between said drip dispenser and said water heating coil; and a filter basket mounted on said housing disposed between said drip dispenser and said carafe. 2. The coffee maker according to claim 1, further comprising a tap connected to said water reservoir for dispensing hot water.3. The coffee maker according to claim 1, further comprising a refillable fuel tank containing a liquid or gaseous combustible fuel.4. The coffee maker according to claim 1, further including three mounting clips in the housing to hold the burner in place, wherein the burner has a generally disc-shaped upper surface for emitting a mixture of vaporized fuel and air upward through a plurality of outlet apertures along the perimeter thereof, a generally disc-shaped lower surface including an inlet opening at the center thereof for receiving a mixture of vaporized fuel and air from an inlet conduit, and a generally annular space between the upper surface and the lower surface for distributing the mixture of vaporized fuel and air from the inlet radially outward to the outlet apertures.5. The coffee maker according to clam 4, wherein the upper and lower surfaces of the burner meet as a radially outwardly extending seam along a common peripheral edge of the two surfaces.6. The coffee maker according to claim 5, wherein each mounting clip includes a pair of notches, and the distal end of each arm of the brace includes an attachment pin having a horizontal shaft such that one of the two notches of each mounting clip receives and securely holds a portion of the seam of the peripheral edge of the burner, and the second notch receives and holds the shaft of a respective attachment pin, thereby securely fastening the burner and brace to the housing.7. The coffee maker according to claim 6, wherein each mounting clip includes a bendable tab that is movable from an initially vertically upward position to a final horizontal position, such that before the burner-water heater coil assembly is fastened to the mounting clips, the bendable tab is in the vertically upward position and, after the burner-water heater coil assembly is fastened to the mounting clips, the tab is bent to the horizontal position, thereby locking the burner and brace in place in the mounting clips.8. The coffee maker according to claim 1, wherein the combustible fuel is gaseous.9. The coffee maker according to claim 1, wherein the combustible fuel is liquid.10. The coffee maker according to claim 1, wherein the combustible fuel contained in a replaceable or refillable cylinder is selected from the group consisting of propane, butane, white gasoline, kerosene, diesel fuel, naphtha, and peanut oil.11. The coffee maker according to claim 10, wherein the combustible fuel is propane.12. The coffee maker according to claim 10, wherein the combustible fuel is butane.13. The coffee maker according to claim 10, wherein the combustible fuel is white gasoline.14. The coffee maker according to claim 10, wherein the combustible fuel is kerosene.15. The coffee maker according to claim 10, wherein the combustible fuel is diesel fuel.16. The coffee maker according to claim 10, wherein the combustible fuel is naphtha.17. A method of replacing a water heater coil in the coffee maker of claim 1, comprising the steps of:disconnecting the water heater coil from the water stream; removing each of the three removable connectors to release the water heater coil from the burner-water heating coil assembly; removing the water heater coil from the assembly; inserting a replacement water heater coil in the assembly; reconnecting the three connectors, thereby securing the replacement water heater coil in the integral burner-water heater coil assembly; and connecting the inlet and outlet conduits of the replacement water heater coil to the water stream. 18. A portable automatic drip coffee maker heated by combustible fuel, comprising:a housing containing a fuel stream and a water stream; the fuel stream including: a burner disposed in said housing; a fuel conduit having a first end attached to said burner and a second end adapted for attachment to a fuel tank containing a combustible fuel; and a flow regulating valve disposed in said fuel conduit between said burner and the fuel tank for regulating the flow of fuel to said burner; the water stream including: a water reservoir; a water heating coil disposed above said burner; a drip dispenser disposed in said housing above said burner and said heating coil; a water conduit connecting said reservoir, said water heating coil, and said drip dispenser; a support brace holding together said burner and said water heating coil as an integral burner-heater coil assembly, the support brace including three arms extending radially outward from a central opening, and the distal end of each arm including a removable replaceable connector that can be removed to permit the separation of the water coil from the burner-heater coil assembly; a carafe disposed between said drip dispenser and said water heating coil; and a filter basket mounted on said housing disposed between said drip dispenser and said carafe.
