Definitions

  • the present invention relates to mechanism for regulating the flame height in a gas lighter.
  • the invention relates more particularly to a special arrangement of the flint tube, which makes it possible to employ a single screw, arranged in the bottom part of said tube, in order to effect either the exchange of the flint, the exchange of the reservoir or the regulation of the flame, just as required.
  • a gas lighter in accordance with the present invention, includes a flame height regulator, a detachable gas reservoir, an expansion valve carried by said reservoir, a valve lever pivoting in order to open the valve element of said valve and to allow the gas to escape, a flint contained in a flint tube, a flint wheel designed to rub against said flint in order to produce sparks and ignite the gas leaving the valve, said regulator comprising a single flint screw which i screwed into one end of the flint tube which extends through the reservoir in gastight fashion and is movable with respect to said reservoir, said flint screw acting to apply the flint against the flint wheel through the medium of a spring and to fix a detachable base in position and to regulate the flame height as a result of said movement.
  • the flint tube is long and is fixed by a bracket between a partition which splits the body of the lighter into two portions, and a plate which forms part of a platform carried by the said partition.
  • the aforementioned plate forming part of said platform is apertured to permit the extension therethrough of the valve and thereby forms a shoulder with which there cooperates a shoulder on a mobile part of the valve, which part is designed to vary the pressure upon a porous washer trapped between said mobile part and a fixed part, so that when the flint screw is operated, the reservoir is moved en bloc and therefore the fixed part of the valve secured to it, thus altering the compressive pressure exerted upon the porous washer.
  • a base on the flint screw, between its head and the end of the tube which surrounds the flint tube, there are arranged a base, a washerwhich bears against a boss on the detachable base of the body of the lighter, and a spring washer.
  • FIG. I is a vertical section showing the general arrangement of the elements located in the case of a lighter in accordance with the invention.
  • FIG. 2 is a plan view of the underside of the lighter, that is, looking in the direction of the arrow [1 of FIG. I or FIG. 3;
  • FIG. 3 is a vertical section on the line III-III of FIG. 2, showing the reservoir and the bottom part of the lighter;
  • FIGS. 4 and 5 are vertical sections, respectively, on the lines IV-IV and V-V of FIG. 1 or FIG. 3;
  • FIG. 6 is an elevation sectional view of the platform portion of the present invention.
  • FIG. 7 is a plan view of the platform.
  • a gas lighter constructed in accordance with the invention and which has a case comprising a body I open at both ends and being rectangular in longitudinal section with the shorter sides thereof in the form of circular arcs whose diameter corresponds to the distance between the long sides (FIG. 2), a cap 2 pivotable in relation to the body I, and a baseplate 3 (FIGS. 1 to 3) which is maintained in a seating la therefor at the bottom end of the body I in a manner which will be described hereinafter.
  • the case is divided into two portions (FIGS. 1, 4 and 5) by a partition 4 which (as seen in FIG. 1) extends horizontally across the case and which carries a platform 5.
  • the lower part of the case contains a detachable reservoir 6 constituted by a main portion 6a with a base and lateral walls fitting inside said lower part and a top 6b with a peripheral skirt 60, which skirt is located inside the portion 6a and is soldered in position.
  • This top is shaped as at 7 to define an opening (FIG. 5) for the location of a valve 8 equipped with a wick 9 (FIG. I, 3 and 5) which is located in the reservoir 6, and with a burner valve comprising a rod 10 and a head 11 (FIGS. 1 and 5).
  • a pivotally mounted valve lever 12 (FIGS. 1, 4 and 5) has a forked end 12a which engages the rod 10 beneath the head 11 (as seen in FIG.
  • a spring 13 surrounding the pivot pin 14 urges said lever 12 downwards into a position in which its forked end 12a is disengaged from the head I I of the burner and the lever 12 is automatically raised, when the cap 2 is lifted, by a roller 15 (FIG. 4) carried on a spindle 16 in a manner which will be described hereinafter.
  • the cap 2 comprises a top 2a and a peripheral skirt 2b and is pivotally attached to the body I by a conventional kind of hinge comprising a block 17 fixed to the cap 2 (FIG. 1).
  • One end I9 of each of two links 18 is pivotally secured to the block I7 and the other end 20 of each of said links is connected to one end of a link 21 whose other end is articulated to the spindle 16.
  • the joint between the respective ends of the links 20, 2I is adapted to move in an elongated rectilinear slot 22 formed in the platform 5. the latter being made up of two horizontal plates 5a, 5b and two vertical cheek plates 5c connected together by a vertical portion 5d (FIGS.
  • the spindle 16 is adapted to move in elongated arcuate slots 23 in a toothed sector 24 having two arms 24a, 24b (FIG. 4) and arranged to pivot about a pivot pin 25, said sector being in constant mesh with a gear 26 fixed to a composite driver 27, 28 in which a flint wheel 29 is fixed.
  • Said driver pivots in an opening 30 formed in the top plate 5a of the platform 5, and contains a bore 31 through which extends the upper end of a flint tube 32 containing a flint 33 and also the upper end of said flint which bears against the flint wheel 29 (FIGS. 1 and 4).
  • the flint tube 32 constitutes one of the features of the present invention and is very long and extends over virtually the full height of the body 1 of the lighter as can be clearly seen in FIGS. 3 and 4.
  • Said tube 32 is fixed centrally by a collar 32a (FIG. 4) in a counterbore 34a formed in a bore 34 in the bottom plateSb of the platform 5 and extends through the reservoir 6 within a tube 35 which is soldered in gastight fa on to the top and bottom of said reservoir, said collar 32a being held between said partition 4 and said platform 5 which are connected to one another by a screw (see FIG. 5).
  • the bottom end of said tube 32 is threaded in order 0 coact with a flint screw 36 (FIG.
  • Said bore 38 is extended, inwa..1ly of the lighter body 1, by an annular boss 34 which is integral with said baseplate 3 and which contains an opening 380 for the extension therethrough of the screw 36 and the head 39a of a ring 39 which is slipped over said screw 36 and which bears against the bottom end of the tube 35, said bottom end projecting downwardly slightly below the level of the base of the reservoir 6, and said opening 38a being coaxial with the bore 38.
  • a base washer 40 slipped over the stem of the base 39 bears against that part of the boss 3a which defines the opening 380 (see FIG. 3) and a thrust washer 41, for example, a spring washer or Belleville washer, is arranged between the head 36a of the flint screw and the washer 40.
  • Said thrust washer 41 helps to keep the baseplate 3 in position in its seat Ia at the bottom end of body I, and its loading is calculated so that the head 36a is exactly flush with the bottom face (external face) of the baseplate 3. However, at the same time, it leaves the flint screw 36 and its base 39 entirely free for rotation about its axis of rotation.
  • the spring 37 because of its substantial length, is centered at its bottom end by an upwardly extending spigot 36b of the screw 36 (FIG. 3).
  • the flint 33 does not bear directly against the opposite end of the spring, but rests against the top surface of a head 43 said head being extended downwardly to form a downwardly extending spigot 43a which centers the upper end of the spring (FIG. 3).
  • the head 36a of the screw has a groove'44 therein (FIGS. 2 and 3) in order to enable a suitable tool (for example the edge of a coin) to be inserted for the purpose of rotating the screw about said axis in order to regulate the flame height in the manner hereinafter described.
  • the valve 8 is of the conventional kind and does not in itself form part of the present invention. Accordingly, only those essential elements thereof which are necessary to an understanding of its operation will be described. Said valve is located, as will be seen hereinafter, in an opening 45 in the bottom plate 5b of the platform 5 and in an opening 46 of the partition 4. As FIG. s shows, the body 8a of the valve is fixed in the opening which is formed in the top 6b of the reservoir 6 (for example by soldering) and contains a wick carrier 47 which acts as a thrust or compressing device and around which the wick 9 is wrapped in order to bring said wick into contact with a porous washer 48 (made, for example, of blotting paper) which is located at or in contact with the. un-
  • Said ring 49 is capable of sliding axially in the body 8a through the medium of a seal 50 and under the action of a regulating sleeve 8b which has an annular shoulder 8c.
  • the wick carrier 4'7 is fixed and therefore the degree of compression of the porous washer 48 can be arbitrarily regulated by moving the ring 49 closer to or moving it away from the wick carrier, that is to say, by displacing the sleeve 8b axially of the body 8a.
  • the opening 45 in the plate 5b has a special profile which is shown in FIG. 5. It is not centered on an axis perpendicular to the plane of the plate 517, but instead has an oblique wall which gives the valve 8 a certain degree of tilt as shown in FIG. 5.
  • This wall has three sections 45a, 45b, 45c which define between them shoulders; of which one shoulder 45d is in contact in the assembled condition of the mechanism with the top face of the shoulder 8c, thus acting as a stop when the reservoir 6 is assembled in the case of the lighter.
  • the reservoir 6 would rise or descend since the head 39a of the ring 39 is constantly in contact with the end of the tube 35 soldered to the reservoir. Since the shoulder 8c is up against the shoulder 45d, if the reservoir 6 and therefore the valve 8 is lifted by rotating the screw 36 in, say, a clockwise direction, the porous washer 48 will be further compressed since the sleeve 8b cannot shift. Conversely, if the reservoir is lowered by rotating the screw 36 in an anticlockwise direction, the degree of compression of the washer 48 is reduced. It is, therefore, easy to adjust the flame to the desired height simply by rotating the screw 36 in the appropriate direction of rotation.
  • the toothed sector 24 pivots about its fulcrum pin 25 (see FIGS. 1 and 4) under the action of the spindle 16 moving along the slot 23, and thus moving the sector 24 and its two arms 24a and 24b to their dotted line position illustrated in FIG. I.
  • This movement of sector 24 causes the gear 26 to rotate, since the teeth of these two elements are constantly in mesh in a generally counterclockwise direction about the axis 27a of driv r carrier 27, that is, gear 26 and sector 24 move into the page, as seen in FIG. 4, at their point of engagement, indicated by the numeral 26a in the drawing.
  • Movement of which is gear 26, keyed to the composite driver 27, 28, causes said composite driver to pivot about its axis 27a (FIGS.
  • the upper portion of driver carrier 27, on which the flint wheel carrier 28 is rotatably mounted (about the axis 28:: which is offset with respect to the axis 27a) with the result that projects beyond the edge of the body of the lighter.
  • the users thumb can easily actuate the flint wheel carrier 28 to rotate the latter about its axis 280, so that the flint wheel 29 rubs against the flint 33 and produces sparks which exitihorizontally through a suitable opening formed in the composite driver 27, 28.
  • the roller 15 carried by the spindle 16 has as a consequence of the pivoting of the link 21, come into contact with the valve lever 12 and lifted it, as shown in broken lines in Figure 1, pivoting about the pivot pin- 14 against the action of the spring 13.
  • the rod 10 and its head I l have thus been lifted and gas escaping from the reservoir 6 will have been enabled to pass through the head 11 of the valve and will have been ignited by the sparks produced by the friction of the flint against the flint wheel.
  • the screw 36 is unscrewed and the baseplate 3 can then easily be withdrawn and the reservoir 6 extracted.
  • the valve lever 12 under the effect of its spring 13, pivots downwards about its pivot pin 14, disengaging the head I I of the burner.
  • the valve is no longer fixed in position andthe reservoir can now be lifted away freely.
  • the sleeve 81; of the valve lifts the lever 12 into the position shown in full line in FIG. 1, that is to say, to the position shown in FIG. 5.
  • the forked end 12a surrounds the stem or neck of the burner, and when the cap 2 is opened, the lever 12 engages with the head 11 and lifts it in the manner hereinbefore described.
