Title: Combination lantern, regulator-valve, and high pressure propane cylinder

Abstract: A combination propane lantern, pressure regulator-valve, and pressurized propane fuel container in which the lantern is supported by the regulator-valve and the propane container, and the rate at which fuel is delivered to the lantern remains substantially constant and independent of pressure within the propane cylinder and ambient temperature. The lantern includes a burner assembly which extends upwardly from the base of the lantern, and the regulator-valve is connected to the burner assembly. The regulator-valve housing is provided with an internally threaded recess into which the connector fitting of the propane container is screwed, and the container thereby supports the regulator-valve and the lantern. The regulator-valve includes a rotatable adjusting knob which can be used to vary the fuel flow through the regulator-valve between fully closed and fully opened positions and therefore also serves as an on-off valve.
