Definitions

  • the present invention relates to a gas lighter with a reservoir, removable or not, for a liquefied combustible gas under pressure and an adjustable flow-restraining device, in which the gas, on its path between the interior of the reservoir and a burner, is led to pass between two clamping elements, between which is inserted a flowrestraining wad, and which can be clamped more or less tightly, on both sides against this wad by setting an adjusting screw.
  • the gas flow-restraining wad is made of leather, preferably natural, 'which presents two layers of different porosities, one of coarser porosity, situated, in the case of natural leather, on the inner side, also called flesh side and the other, of liner porosity, situated on the outer side, also called grain side, the combustible gas, between the reservoir and the burner, being led to pass successively through these two layers, preferably first the layer of coarser porosity oriented towards the upstream, and then the layer of finer porosity, oriented towards the downstream, with respect to the direction of ow of the gas.
  • the restraining wad is constituted by a ring of flexible material, preferably porous, pierced without removal of material and threaded on a cone forming the central part of the annular clamping surface of one of these elements and projecting towards a gas passage orifice, provided in the corresponding opposed clamping surface of the other element, the ensemble being inserted in the gas outlet channel of the reservoir by the peripheral side of the one of the faces of the ring and by the central orifice on its other face.
  • this member is coupled in rotation with this screw by means adapted to act in the manner of a screw driver to cause, by the simple rotation of this member in one direction or in the other, the screwing or the unscrewing of this adjusting screw
  • the rotary member advantageously comprising an adjustable axial abutment, adapted to project 'by a greater or lesser amount with respect to the end of this member turned towards the above mentioned regulating screw and which, consequently, permits the adjustment of the extreme position adapted to be reached by the adjusting screw in the completely unscrewed position which corresponds to the maximum gas flow.
  • FIG. l shows, partially in elevation, partially in axial section, a part of a gas lighter established according to a first embodiment of the invention
  • FIG. 2 shows, in axial section, a part of a lighter established according to another embodiment of the invention
  • FIG. 3 shows, in axial section, a part of a lighter established according to still another embodiment of the invention.
  • FIG. 4 shows, in perspective, a member forming part of the lighter of FIG. 3.
  • a gas flow-limiter with which the user can himself adjust the height of the llame to his personal convenience.
  • This how-limiter generally comprises an adjusting wad 2, clamped between two opposed surfaces 3 and 4, of adjustable separation, the wad and the surfaces being inserted in such a manner, in the gas outlet channel, between a reservoir 5 of liquefied gas under pressure, removable or not, of the lighter, and a burner 1, that by moving one of these surfaces towards or away from the other, a decrease or an increase respectively is obtained of the flow of the gas issuing from the burner 1.
  • the wad 2 is made of leather presenting two layers of different porosities, one 2a, denser, of finer porosity, located in the case of natural leather on the outer side, also called grain side, and the other 2b, of coarser porosity, on the inner side, also called liesh side; the gas contained in the reservoir 5 must pass successively through these layers before being able to leave this reservoir by the burner 1.
  • the wad 2 is advantageously inserted in such a manner in the gas outlet channel that the gas can only leave the reservoir -5 by passing through iirst the layer of coarser porosity 2b, oriented towards the upstream, and then, the layer of finer porosity 2a, oriented towards the downstream with respect to the direction of flow of the gas.
  • the reservoir 5 contains a tube 6 which passes through it in a fluid-tight manner, this tube opening on two opposite walls 5a, 5b ofthe reservoir.
  • the tube 6 presents an intermediate annular shoulder 6a.
  • the part 6b of the tube 6 contains a coaxial gas outlet control valve 7 which a return spring 8 applies in a fluid-tight manner against the edge of the central hole 9 of this shoulder and whose tubular control rod 10, serving as a gas outlet conduit, can form in a manner known in itself, by its free end, the burner 1.
  • An annular sealing joint 12, inserted between the screw 11 and the tube 6, ensures the sealing downstream of an opening 13 provided radially through the wall of the tube 6 and opening in this tube under the wad 2.
  • the gas contained under pressure in the reservoir can pass through the opening 13 in the tube 6, under the wad 2, pass through this wad, then issue through the central hole 9 in the part 6b of the tube, to penetrate through a radial hole 14 in the tubular rod 10 and issue at the end of this rod through the burner 1.
  • the wad 2 By screwing more or less tightly the clamping element 11 in the tube 6, the wad 2 is compressed 'more or less tightly, and consequently, the flow of the gas leaving the reservoir through this wad or between the sides of this wad and its clamping surfaces is decreased or increased.
  • the wad 2, made of leather, according to one feature of the present invention presents, by its two different porosities, not only advantageous properties in themselves for restraining the flow, but also the advantage of not becoming shabby when it is urged in opposite directions by the two clamping surfaces 3 and 4 turning one with respect to the other during the clamping of the wad.
  • the wad 2 is advantageously established in the form of a ring pierced at its centre without removal of material and threaded on a cone 15, forming the central part of the annular clamping surface 4 of the screw 11 and projecting towards the hole 9, provided in the centre of the corresponding clamping surface 3 of the tube 6.
  • an increase of the clamping of the ring 2 by screwing the element 11 in the tube 6, produces in the thickness of the ring 2 a compression which, more quickly than elsewhere, increases near the cone 15, and particularly in the neighbourhood of the inlet of the hole 9, that is to say in an annular zone of the ring through which the gas, coming from the reservoir 5, must necessarily pass before being able to arrive at the valve 7
  • a determined reduction of the gas flow can be obtained with a minimum stress, since instead of being uniformly distributed in the entire thickness of the ring 2, the compression of this ring is essentially limited to the region where it is effective for limiting the flow of gas.
  • the ring 2 is advantageously fitted in a housing whose bottom is formed by the surface 3 with the central hole 9, whereas the clamping surface 4, adapted to penetrate into this housing there to compress the ring 2 extends to the neighbourhood of the periphery of this housing while allowing an annular slot to remain, along this periphery, for the passage of the gas through the ring 2.
  • This annular slot is advantageously obtained by a chamfer 16 at the periphery of the frontal clamping surface 4 of the screw 11, the opening 13 being provided through the part 6c of the tube 6 so that it opens opposite to this chamfer 16.
  • the gas under pressure coming from the reservoir 5 can, by passing through the opening 13, reach the periphery of the lower surface of the ring 2, which obliges it, in order to reach the opening 9, when the Valve 7 is raised, to pass through the porous ring 2 from one side to the other.
  • the reservoir 5 can, of course, be completely filled with 4 material adapted to absorb the liqueed gas under pressure that it contains.
  • the opening 13 is open into the reservoir 5, between these two tubes, so that its cross section is divided, by the plane common to the axes of the tubes 6 and 17, into two parts at least approximately equal, whose edges are separated as little as possible from that plane, and to insert between these two tubes a tampon B of material adapted to absorb the liquid gas which is thus applied against the opening 13 with a maximum pressure, localized along the generatrices determining the minimum distance between the two tubes.
  • the rest of the reservoir can then be left empty of any stuiling, thus increasing the capacity for receiving a greater quantity of liquefied gas under pressure.
  • the adjusting screw 111 for adjusting the height of the llame which does not con tain either valve or channel for filling the reservoir and whose end remote from the cone is still at the interior of the tube 106, is set by the rotation of a separate rotary member 23 which covers the tube 106 on the exterior face 10519 of the lighter and which is axially retained in this tube by lugs 24, radially flexible and hooked into a groove 25 provided in the interior periphery of the tube 106.
  • the member 23 is axially immobilized with respect to the tube 106 but can turn at will in the two directions with respect to this tube.
  • the member 23 is coupled in rotation with the screw 111 by means adapted to act in the manner of a screw driver which permit, by the simple rotation of this member in one direction or in the other, the screwing or unscrewing of the screw 111 in the tube 106.
  • these coupling means comprise on the rotary member 23 an axial tongue 26 and, in the screw 111, a diametrical slot 22 in which the tongue 26 slides, thus penetrating into this slot by a greater of lesser amount during the common rotation of the member 23 and of the screw 111 which, in the course of this rotation, is screwed or unscrewed in the tube 106.
  • the tongue 26 and the corresponding slot 22, for the rotary coupling of the member 23 and the screw 111 can be replaced by other pairs of projections and hollows, provided that these corresponding projections and hollows form cylinders in the direction of the common axis of the screw 111 and of the tube 106, without however being of revolution about this common axis.
  • Their cross section can in particular be polygonal.
  • the inlet of the tube 106 is preferably flared outwardly in the form of a cone 27 which facilitates putting the member 23 in place, due to the fact that, when then lugs 24 are pushed axially in the cone 27, they bend towards the axis and, then, right themselves again elastically, when their end projecting towards the periphery has been able to penetrate into the groove 25, to hook there with the member 23.
  • this adjustable axial abutment by acting on this adjustable axial abutment, the manufacturer will have the possibility of adjusting the extreme position adapted to be reached by the adjusting screw 111 when the user unscrews this adjusting screw completely, in Iwhich extreme position the end of the adjusting screw 111 oriented towards the rotary member 23 abuts against this axial abutment.
  • FIGS. 3 and 4 An advantageous embodiment of such an adjustable abutment is shown in FIGS. 3 and 4 in which various parts of the lighter fullling analogous functions to those shown in FIG. 2 have been designated by the same reference numerals increased by one hundred, the rotary member 123 being here axially retained in the tube 206 by an expansible split ring 28 and the adjusting screw 211 acting by its end on a push-piece 29 of a device (not shown) for restraining the flow of gas.
  • the adjustable axial abutment carried by the setting member 123, comprises, in an axial hub 123a of this member, a tapping 123b, and, screwed in this tapping, a screw 30 of sufficient length to project to a greater or lesser extent above the upper end of the hub 123a of the member 123, the rotary coupling tongue 126 having the form of an upside down U, in order to straddle the end of the screw 30, this screw nevertheless projecting out at both ends from this tongue, so that itsy projecting parts can effectively play the role of axial abutments for the adjusting screw 211.
  • the rotary member 23 ⁇ or 123 by its part accessible from the exterior, can be very fiat or even embedded in the bottom of the lighter, in which case it is appropriate either to make it project slightly at its periphery out from each side of this bottom, or to provide it, in its face directed towards the exterior, with a diametrical groove 32 (FIG. 3) in which the user can insert a coin thus using it as a screw driver.
