Abstract
A flame lighter has a blue flame burner and a luminous flame burner supplied with gaseous fuel from a reservoir through separate valves, and a single ignition mechanism. A first operation ignites the blue flame burner and a second operation opens the valve for the luminous flame burner so that the luminous flame is ignited from the heat of the blue flame burner, whenever a luminous flame is desired.
Claims19
A flame lighter comprising:
- a casing containing at least one reservoir for liquefied gaseous fuel;
- a first, blue flame burner, which is arranged to be supplied with gaseous fuel from the, or one of the, reservoir(s) through a first valve;
- a manually operated ignition mechanism for igniting the fuel at the first burner so that the fuel burns near to a glow element which is thus heated by the blue flame;
- and a second, luminous flame burner, which is arranged to be supplied with gaseous fuel from the, or another of the, reservoir(s) through a second valve;
- a nozzle of the second burner being adjacent to the glow element of the first burner so that the fuel at the second burner is ignitable by heat generated at the first burner whenever the first burner is burning and the second valve is open, and means for closing the first valve while the second valve remains open so that only the luminous flame continues to burn.
