Definitions

  • ABSTRACT [21] Appl. No.: 190,605
  • a cigarette-lighter of the type usually comprising a cap enclosing a valve actuating lever projecting therefrom
  • this lever is dispensed with and its function transferred to the cap itself, formed with an inwardly bent pressing for engagement with the valve stem, act- France 70.38254 [51] Int. F2311 25/00 ing as a burner, the cap being pivoted to trunnion- [58] Field of Search............ 431/150, 276, 277, 131 forming bosses moulded integrally with the head of the lighter.
  • the present invention relates to gas-operated cigarette lighters of the type wherein a valve is adapted to be opened by pivoting a lever housed under a fixed cap and projecting from the rear portion of said cap, the projecting lever portion being engaged by the users finger and pressed after the same finger has actuated the flint wheel and escaped therefrom.
  • the cigarette lighter according to this invention is characterized in that the aforesaid valve opening lever is dispensed with and its function transferred to the cap proper, by mounting this cap on a pivot pin carried by the head of the lighter body.
  • valve stem and the cap are operatively interconnected through an inwardly bent tongue resulting from the pressing of the top of said cap for forming the aperture, permitting the passage of the flame, said tongue being engaged under a projecting portion of the valve stem.
  • the pivotal mounting of the cap is obtained by molding the fixed head of the ligher body with a pair of integral bosses over which perforated side faces of the cap are engaged.
  • another pair of bosses may also be molded integrally with thehead to constitute other trunnions for rotatably supporting the serrated flint wheel.
  • FIG. 1 is a vertical axial section, taken along line 1-1 of FIG. 2, showing the improved valve action of this invention
  • FIG. 2 is a sectional view taken along line 22 of FIG. 1, and
  • FIG. 3 is a plan view from above of the cigarettelighter.
  • a head 1 of injection-moled plastic material is fitted in fluid-tight relationship onto a reservoir 2 constituting the body of the lighter.
  • This head 1 comprises a well from from the bottom of which emerges a wick 3, this well also containing in a fluid-tight manner a valve guide 4 and valve seat 5 en gageable by a valve member 6 carried by a hollow stem 7 whose upper and outer end constitutes a burner, this valve member 6 being constantly urged to its seated position by a spring 8 surrounding the valve stem 7.
  • the length of the flame can be adjusted by horizontally moving a lever 9 solid with the valve guide 4 so as to adjustably tighten the upper end of wick 3 through tapered surfaces 10.
  • the head 1 also carries a serrated flint wheel 11 and a pyrophoric flint 12 urged by a spring 13 for engagement with said wheel.
  • the upper portion of said head 1 is covered by a cap or cover 14.
  • the cap 14 is pivotally mounted on the head 1 and an aperture 15, permitting the passage of the flame from the burner, is formed by pressing and bending a lug 16 from the head to the shape shown in FIG. 1, the pressing operation forming simultaneously a notch 17 in the inner end of said lug, the side arms of this notch being engaged, on either side of the upper portion of said valve stem or burner 7 and under a spring washer l8 engaging with its inner teeth a groove, formed on said valve stem or burner 7.
  • cap 14 is provided with aligned holes engaged by trunnion-forming bosses 19 molded integrally with lugs 20 carried by said head 1.
  • the cap 14 is pivoted to the head 1 and any movement thereof in the direction of the arrow (FIG. 1) is attended by the tilting of the cap in the clockwise direction (as illustrated) and therefore by an upward movement of the valve stem; thus, the unseated valve permits the escape of gas from the reservoir 2.
  • another pair of bosses 21 are molded integrally with the lugs 20 to serve as trunnions engaged directly in a bore in the flint wheel 11.
  • a hand lighter comprising a body having a reservoir for containing a combustible substance in liquid state under pressure, a head fixed on said body, a burner carried by said head and including a valve controlling the outlet of the combustible substance in gaseous form from the reservoir, a flint wheel rotatably mounted on said head, a flint chamber in said head for support of a flint in proximity to said flint wheel, said valve including a valve stem, and a spring acting on said valve stem to close the valve, a cover pivotably mounted on said ,head and enclosing the same, said head including first integral bosses on which said cover is pivotably supported and second integral bosses on which said flint wheel is rotatably mounted, and means on said cover operatively connecting the cover to said stem to move the stem against the opposition of the spring when the cover is pivoted, said cover having an operative rear portion adjacent the flint wheel for being pressed by a finger of
  • a lighter as claimed in claim 1 wherein said head comprises upstanding lugs with which said first and second bosses are integral.
  • a lighter as claimed in claim 1 wherein said means connecting the cover to the stem comprises 2. lug inwardly bent from the cover to form an aperture therein to provide access to a flame at said burner, said stem including a projecting portion extending upwardly from the head to a position below said aperture, said lug engaging said projecting portion of the stem, said flint wheel extending through said cover.
  • valve includes a valve guide fixed in said head and having an outlet orifice for the gaseous combustible substance, said valve stem being slidable in said valve guide to selectively open and close said outlet orifice, said spring being mounted in said guide and acting between said stem and guide.
