Abstract
A lighter of the disposable type is disclosed for burning a fuel such as butane contained in a body member which defines an internal fuel chamber having an opening through which the fuel may pass and including a dual action valve which controls the flow of gaseous butane fuel to a burner in either of two modes. The first mode includes an 'on/off' fuel control lever; the second mode includes a variable fuel flow control member which determines the height of the flame produced at an output orifice of a burner by a sparking wheel and sparking flint by controlling the amount of fuel passed therethrough as a function of the rotational position of a rotatable control member. The lighter further comprises novel means to pre-determine the height range of the flame thus produced, by limiting the rotational range of travel of the flame height control member.
