Abstract: A fuel cap includes a filler-neck closure adapted to mate with a filler neck to close a mouth opening into a fuel-conducting passageway formed in the filler neck. The filler-neck closure includes a vacuum-relief valve and a handle arranged to overlie the filler-neck closure and gripped by a user during removal of the fuel cap from the filler neck.

Abstract: A fuel cap includes a filler-neck closure including a pressure-relief valve and a vacuum-relief valve and a handle arranged to overlie the filler-neck closure. The fuel cap also includes a torque-transmission ring arranged to lie between the handle and the filler-neck closure.

Abstract: A fuel gauge is adapted to extend into a fuel tank to enclose liquid fuel in the fuel tank and to sense the level of liquid fuel in the fuel tank. The fuel gauge includes a fuel-level indicator having a needle and a buoyant float exposed to the liquid fuel in the fuel tank. The needle moves in response to changes in the level of liquid fuel in the fuel tank sensed by the buoyant float.

Abstract: A power source is provided for a machine. The power source includes an engine and an engine fuel system of the type that generates fuel vapor containing hydrocarbon material.

Abstract: A fuel cap is provided for use in a filler neck of a tank of a vehicle having body portions which are conductive. The fuel cap includes a housing sized to fit into the filler neck and a cover coupled to an upper end of the housing. The cover is made of a non-conductive resin and an electrically conductive coating covering at least a portion of the non-conductive resin. The coating has a thickness of between approximately 0.1 and 0.6 mil. The fuel cap further includes a conductive discharge member having a first end engaged with the electrically conductive coating of the cover and a second end adapted to be coupled to one of the filler neck and the body of the vehicle to dissipate static charge.

Abstract: A filler neck closure includes a closure base, a handle, and an apparatus mount. The closure base is adapted to mate with a fuel tank filler neck to close an opening into a fuel-conducting passageway formed in the fuel tank filler neck. In certain embodiments, a fuel treatment apparatus and/or vent apparatus is coupled to the apparatus mount.

Abstract: A foldable hand truck apparatus having 1) a main support frame assembly; 2) a support wheel assembly connected to the main support frame assembly which resembles a conventional hand truck structure; 3) an extendable handle assembly having a handle support tube which is anchored to the main support frame assembly; and 4) a dual foldable load assembly pivotally connected to the main support frame assembly. The extendable handle assembly includes a handle member telescopingly mounted within the handle support tube and movable from a compact storage position laterally of the handle support tube to a locked usage position. The dual foldable load assembly includes a luggage or large article support frame and a load support plate, both pivotally connected to a lower portion of the main support frame assembly. The load support plate is first pivotal to a position 90 degrees perpendicular to the main support frame assembly for carrying smaller loads thereon or gripping an edge portion of an article to be moved.

Abstract: A hand truck stair crawler assembly having a new and novel stair engaging crawler assembly mounted on a conventional hand truck assembly. The stair engaging crawler assembly includes a pair of spaced, cooperating stair crawler assemblies secured to the hand truck assembly, each having a main roller support assembly with a main roller assembly connected thereto. The main roller support assembly includes a pair of spaced bearing retainer plates secured by a plate connector assembly to the hand truck assembly. The main roller assembly includes a plurality of spaced roller bearings mounted within the bearing retainer plates and having an endless belt member mounted thereon for engagement with stairs for traversing thereof. The roller bearing member is of a special design having a central body portion with outer end belt retaining sections to support the endless belt member having contact and support entirely on a plurality of cooperating roller bearing members.
