ABSTRACT:
A portable lighter for burning a combustible fuel having a locking means which must be arranged in an operating position for the lighter to be operated to produce a flame. The lighter automatically returns to a non-operating condition after a striking or a single operation. The safety mechanism is a rotatable and axially moveable lock means with a projection which engages an operating member to prevent the operating member from opening the valve to emit the combustible gaseous material. The lock means is axially and rotatably biased to cause the operating member to return to a position in which the lighter is not operable after a striking operation.
