Moore - Web page: https://patentgrep.com/patent/USRE31316E ## 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 throw-away 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. ## Claims ### Claim 1 An elongated igniting device for a conventional cigarette lighter having a head end with a rotatable flint wheel adjacent a movable valve actuator controlling flow of fuel through a valve to an outlet port, said device comprising: an elongated shank; a handgrip on one end portion of said shank; holding means on the opposite end portion of said shank for releasably retaining the cigarette lighter with the head end facing away from the hand grip; an actuator rod guided for reciprocable movement parallel to said shank, said rod having an outer extension beyond the head end of the lighter and being movable between extended and retracted mode conditions relative to the lighter head end; spring means biasing said actuator rod toward its said extended mode condition; trigger means adjacent the hand grip and connected to the actuator rod, effective in response to pull on the trigger, to move said actuator rod to said retracted mode condition against the bias of said spring; and igniting means supported on said outer extension in position to engage and rotate the rim of said flint wheel and depress said valve actuator to ignite the lighter in response to movement of the actuator rod to its said retracted mode condition. ### Claim 2 (depends on 1) An elongated igniting device according to claim 1 in which the igniting means includes an elastic friction member engageable with the flint wheel rim offcenter. ### Claim 3 (depends on 2) An elongated igniting device according to claim 2 in which the elastic friction member is a cantileverly mounted coil spring friction member having a free end facing the head end of the lighter and aligned with the flint wheel along the line of movement of the coil spring friction member. ### Claim 4 (depends on 3) An elongated igniting device according to claim 3 in which the coil spring friction member is positioned for its free end to engage both the rim of the flint wheel to generate sparks and to hold the valve actuator in open position responsive to movement of the actuator rod to its said retracted mode condition. ### Claim 5 (depends on 3) An elongated igniting device according to claim 3 in which the coil spring friction member is mounted diagonally relative to its line of movement with the actuator rod enabling an ignition sequence in which the free end of the coil spring friction member initially engages the rim of the flint wheel offcenter to start it rotating followed by laterally shifting to engage the flint wheel with the side of the coil spring friction member and generate sparks followed by engagement of the free end of the coil spring friction member with the valve actuator to maintain a flame. ### Claim 6 (depends on 3) An elongated igniting device according to claim 3 in which the coil spring friction member is supported on an elastic core enabling the spring to deflect laterally after engaging the rim of the flint wheel, thereby rotating the flint wheel by an initial engagement with the free end of the coil spring friction member followed by engagement with the side of the coil spring friction member. ### Claim 7 (depends on 6) An elongated igniting device according to claim 6 in which the elastic core is at least one leaf spring. ### Claim 8 (depends on 6) An elongated igniting device according to claim 6 in which the free end of the coil spring friction member engages the valve actuator to hold the fuel valve open when the actuator rod is in retracted mode condition. ### Claim 9 (depends on 6) An elongated igniting device according to claim 6 in which the elastic core is a cantilever member with a free end which engages the valve actuator to hold the fuel valve open when the actuator rod is in retracted mode condition. ### Claim 10 (depends on 5) An elongated igniting device according to claim 5 in which at least the free end of the coil spring friction member has compressible coils which compress on initial engagement with the flint wheel and which subsequently expand when it shifts laterally enabling the expanding coils to facilitate rotation of the flint wheel. ### Claim 11 (depends on 5) An elongated igniting device according to claim 5 in which the holding means includes elastic means urging the head end of the lighter toward the path of movement of the coil spring friction member thereby enabling the lighter to be shifted laterally by the coil spring friction member to facilitate igniting the lighter. ### Claim 12 (depends on 11) An elongated igniting device according to claim 11 in which the coil spring friction member is supported on a relatively rigid core member movable with said actuator rod. ### Claim 13 An elongated igniting device for a conventional cigarette lighter having a head end with a rotatable fling wheel adjacent a movable valve actuator controlling flow of fuel through a valve to an outlet port, said device comprising: an elongated shank; a handgrip on one end portion of said shank; holding means on the opposite end portion of said shank for releasably retaining the cigarette lighter with the head end facing away from the hand grip; an actuator rod guided for reciprocable movement parallel to said shank, said rod having an outer extension beyond the head end of the lighter and being movable between extended and retracted mode conditions relative to the lighter head end; trigger means adjacent the hand grip and connected to the actuator rod, effective in response to pull on the trigger, to move said actuator rod to said retracted mode condition; and igniting means supported on said outer extension in position to engage and rotate the rim of said flint wheel and depress said valve actuator to ignite the lighter in response to movement of the actuator rod to its said retracted mode condition. ### Claim 14 (depends on 13) An elongated igniting device according to claim 13, in which the igniting means includes an elastic friction member engageable with the flint wheel rim. ### Claim 15 (depends on 13) An elongated igniting device according to claim 13 in which the igniting means includes a friction member mounted on a spring member and engageable with the flint wheel rim.
