Definitions

  • This invention relates to cigarette lighters of the type using liquified gas such as butane for fuel, and more particularly to a lighter which may be thrown away after the, initial supply of fuel has been exhausted.
  • gas fueled lighters (popularly called butane lighters) have become more and more popular due to the fact that a large supply of gaseous fuel in liquified form can be stored in the lighter in a relativly small space. It is possible to store in a space of about A cubic inch volume sufficient liquified gas to supply the necessary fuel in normal usage for a period of several months.

  • FIGURE 6 is an enlarged fragmentary side sectional view of the valve and burner assembly along lines 6-6 of FIGURE 5;
  • FIGURE 7 is a sectional view along lines 7-7 of FIGURE 5;
  • FIGURE 8 is a sectional view along lines 8-8 of FIG- URE 5;
  • FIGURE 9 is a fragmentary side view of the present lighter showing the fingerpiece in an open position.
  • the lighter 10 includes a casing 12 which may be made of any moldable plastic material such as polyethylene, polypropylene, polyvinyl chloride or any similar material which is at least resistant to the liquified gaseous fuel.
  • the casing 12 is advantageously open at its upper end so that a valve and flint support 14 may be inserted into the casing.
  • a valve and burner assembly 16 is placed within the support 14.
  • a head mechanism 18 is provided and it is also inserted at least partially into the casing 12 and in contact with the valve and burner assembly 16. To insure that the casing 12 will properly support the valve and flint support 14, as well as the head mechanism 18, a stiffener 20 is provided in the form of a rib within the casing 12.
  • An interior shoulder 19 is provided within the casing 12 and it is upon this shoulder that the valve and flint support 14 rests. To insure a gas type fit between the support 14 and the casing 12 a suitable adhesive may be used to hold the support 14 securely in place.
  • the support 14 includes a valve body 21 into which is positioned a valve cap 22 by means of screw threads.
  • a valve cap 22 Contained within the valve cap 22 is a burner tube 24, through which there extends a bore 26.
  • a valve seal 28 of suitable gas resistant material such as neoprene is provided.
  • a valve seat. 30 Also contained within the valve cap 22 and positioned directly beneath the valve seal 28 is a valve seat. 30.
  • the valve seat 30 has a vertical opening 31 therein and it overlies a fuel pad 32.
  • the fuel pad 32 in turn is positioned over a bore 34 in the valve body 21.
  • the bore 34 in turn is in communication with a tube 36 which extends well into the lower portion of the casing 12 and is in contact with the supply of liquified gas fuel F.
  • the fuel F in the casing 12 is usually butane maintained in a liquified form under slight pressure so that it will change to a gas when exposed to atmospheric pressure. It is by means of the fuel pad 32 that the liquified gas F is exposed to atmospheric pressure. This occurs when the burner tube 24 which is normally maintained in a closed position by means of a burner spring 38 is raised upwardly. The upward movement of the burner tube 24 lifts the valve seal 28 away from its covering engagement with the opening 31 in the valve seat 30.
  • a bifurcated valve lifter 44 is provided in order to raise the burner tube 24 so that gas may escape through the opening 42.
  • the amount of fuel which escapes through the opening 42 is determined by the degree of pressure which is exerted by the valve seat 30 against the fuel pad 32; the greater pressure the less the flow of fuel.
  • the degree of pressure is regulated in a coarse adjustment by means of the threaded connection between the valve body 21 and the valve cap 22.
  • an adjuster 46 is fitted about the upper portion of the valve cap 22 in wrench-like fashion so that a slight movement of the cap 23 may be made relative to the body 21.
  • an O-ring 47 is provided beneath the valve seat 30, as shown in FIGURE 6.
  • the head mechanism 18 includes a U-shaped support frame 48 consisting of a pairof arms 50 and a center portion 52. Extending downwardly from the arm 50 are tabs 54 which are provided with inwardly stamped notches 56 which act as detents. In order to insert the head mechanism into fixed contact with the valve and flint support 14, the support frame 48 with the attached head mechanism is pressed downwardly so that the notched detents 56 engage shoulders 58 provided on the support 14.
  • a fingerpiece 60 is rotatably mounted on the support frame 48.
  • the fingerpiece 60 includes a top portion 62 and downwardly extending arms 64.
  • a sparkwheel 66 is mounted on the arms 64 by means of a sparkwheel bearing 68 through which isextended a support pin 70.
  • the pin 70 extends through the cutouts 72 in the arms 50 of the support frame 48.
  • On each end of the pin 70 a cam bearing 74 is provided and the bearing 74 is positioned within the cutout 72.
  • Thesparkwheel 66 has a ratchet plate 76 mounted on one side thereof.
  • a pawl plate 78 is provided and rotatably positioned about the sparkwheel bearing 68.'The plate 78 abuts against a portion 79 of the fingerpiece 60 so that the plate 78 is rotated whenever the fingerpiece 60 is rotated.
  • the rear portion 80 of casing 12 is fitted with cutouts 82 for arm 64.
  • the sparkwheel When the fingerpiece 60 is rotated, the sparkwheel turns causing a field of sparks to be generated since there is provided within the flint holder 84 a .flint 86 which is pressed against the sparkwheel by a spring 88.
  • the arms 64 contact the rear portion of the valve lifter 44 causing it to be" pivoted about a fulcrum 90.
  • the bifurcated front end of the lifter then contacts the burner tube 24 and opens the valve as discussed previously.
  • the mounting of the fingerpiece 60 is not rigidly fixed.
  • the bearing earns 74 advantageously permit a floating action to be obtained. Since the size of the openings 72 in the arms 50 of the support frame 48 is greater than the cam bearing 74 the action of the flint spring 88 on the flint 86 and in turn the sparkwheel 66 causes the bearing 74 to be urged upwardly within the cutout 72 so that the fingerpiece is positively cammed into a closed position. By this same floating arrangement when the fingerpiece is rotated to an open position, as shown in FIGURE 9, the bearing 74 acts to cam the fingerpiece into its open position by riding downwardly within the cutouts 72.
  • the cutout and cam arrangement utilizes the spring pressure of the flint spring 88 and eliminates the necessity for a special closure spring for the fingerpiece.
  • valve cap 22 is made of a suitable moldable plastic as are the flame adjuster 46, the fingerpiece 60 and the cam bearings 74.
  • the entire valve and flint support 14 is made of a single. integrally molded piece.
  • a protective metal screen or shield can be providedin the area of the head mechanism adjacent to the top opening 42 in the burner tube 24.
  • a metal shield 92 may be placed on the under surface portion of the top 62 of the fingerpiece 60.
  • a metal shield 94 may be placed within the frame work of the support frame 48 in v order to protect anouter finish of the frame piece. The shields 92 and 94 act as flame protectors.
  • a cigarette lighter of the type described including a casing for holding a supply of liquified gaseous fuel, an integral valve and flint support carried by said casing, a valve and burner assembly of the lift type mounted in said support, a valve lifter for activating said'valve, a spring loaded flint inserted into an opening in said support,
  • a head mechanism including a frame member, a rotatably mounted fingerpiece, a sparkwheel and sparkwheel rotating means, said head mechanism mounted on said support, said sparkwheel contacting the flint, means for movably mounting said sparkwheel and fingerpiece whereby when the fingerpiece is rotated, the valve is opened releasing a stream of gaseous fuel and the sparkwheel is rotated against the flint generating a field of spark into the stream of gaseous fuel, said movable means adapted to maintain the fingerpiece in open and closed positions at the extremes of its rotation under the pressure of the spring loaded flint.
  • a cigarette lighter as defined in claim 1 wherein the means for movably mounting the sparkwheel includes cutout portions in the frame member, a pin for rotatably mounting the sparkwheel on its trans-verse axis, bearing cams positioned in the cutouts and mounted on the pin and said bearing cams being free to move within the cutout portions.
