ABSTRACT:
A cigarette lighter is disclosed having a spark producing wheel, a fuel delivery valve, and a fuel supply tank, all of which are mounted in a case and cooperate with a novel safety interlocking means. The interlock means includes a wheel interlock tooth for locking and unlocking the friction wheel which is actuated by a spring type handle mounted on one side face of the case. The wheel interlock tooth is attached to a coupling means which must be in an advanced position to allow the actuation of the fuel valve lever so that neither the fuel flow nor the spark may be activated unless the safety handle leaf spring is depressed.
