Abstract
An elongated shank has a handgrip at the rear end portion. At the forward end portion there is a holder for releasably retaining a cigarette lighter of the throwaway gas or butane type having a conventional flint wheel and a gas valve actuator. An actuator rod is guided for reciprocable sliding movement along the shank. The rod is urged forward along the shank by a biasing spring and may be pulled backward against the spring by a trigger adjacent the handgrip. An integral outer extension of the rod, forward of the holder, is movable between extended and retracted positions by the biasing spring and the trigger, respectively. An elastic friction member, consisting of a backwardly extending, cantileverly supported, diagonally oriented coil spring is mounted on the outer extension and is movable backward by the trigger to engage and rotate the flint wheel and depress the valve actuator. This ignites the lighter and holds it ignited as long as the trigger is held. The device is adapted for lighting pilot lights of gas appliances, candles, fireplaces, barbecue grills, camping lights and stoves, and the like.
