Abstract: An indexing style Automatic Port Cleaner for cleaning furnace combustion air ports employs multiple cleaning tips and rods enclosed substantially in a furnace windbox. An extension bar enclosed substantially in a furnace windbox to which the cleaning rods are attached with the extension bar carries the cleaning rods and tips in a translating and indexing motion. An extension bar is supported by two fulcrum rods and in turn supported by two fulcrum tubes and two fulcrum housings, the fulcrum housings being supported by a faceplate and fixed relative to the combustion air ports. The fulcrum rods translate relative to the fulcrum tubes while the fulcrum tubes rotate relative to the fulcrum housings. A linear actuator is disposed to create a reciprocating translating motion of the fulcrum rods, extension bar, cleaning rods, and cleaning tips. Indexing creates rotation of the fulcrum tubes, fulcrum rods, extension bar, cleaning rods, and cleaning tips, in a reciprocating fashion about the fulcrum housings.

Abstract: The present invention provides an ignition actuation mechanism for the manual actuator of a spark producing device in a fuel gas lighter to increase the actuation force immediately before spark discharge without unreasonably increasing the actuation force at the initial stages of movement of the manual actuator to reduce that chances of inadvertent ignition by small children, but maintaining good operability for adult users. Movement of the manual actuator is always resisted by a first elastic member while a second elastic member is positioned to resist movement of the manual actuator at a maximum of 30N to 50N after 60% or more of the total movement of the manual actuator required to produce a spark has occurred. Preferably the second elastic member is one or more flexible fingers molded from polyacetal resin.
