ABSTRACT:
A safety mechanism in a utility lighter which includes a lever spring and cam mechanism having a fuel release lever and the safety button. When the cam mechanism is in the locked position, the lever spring blocks the stopper tab preventing depression of the trigger, and the fuel release lever closes the fuel release valve. As the safety button is depressed, the lever spring is moved out of alignment with the stopper tab to permit depression of the trigger, the hub rotates, and the fuel release lever is actuated to open the fuel-release valve. As the safety button is released, the lever spring urges the cam mechanism into the locked position.
