  • Fig. 8 is a view in partial section, to a larger scale of a lighter provided with a device according to a fifth form of construction.
  • Fig. 9 is a view in partial section to a larger scale of a device according to a sixth form of construction.
  • Fig. 10 is a view to a larger scale of another form of construction, the passage being closed.
  • Fig. 11 is a sectional view the passage being open.
  • a lighting device comprising a friction wheel 3 turning on a spindle 4 secured to the body I and against which a pyrophoric element 5 is applied by means of a spring 6 located in a tube 1 secured to the body I.
  • the latter encloses a fuel tank 8, containing a fluid fuel under pressure and connected by a passage 9 to a burner formed, in the example shown in Fig. 1, by the orifice ll] of the passage, which is located in proximity to the friction wheel 3.
  • the passage 9, limited by the inner wall of a metal tube H, is provided with a device for feeding fuel to the burner.
  • This device is formed by a local crushing I2 of the walls of the tube II which is thus provided at this point with a reduction in its internal cross section, a local increase in its flexibility and a curvature of its centre line
  • the feed device is provided with two stops l3 and [4.
  • One, l3, adjustable in position, is movable in the directions of flexing of the tube II; the other H located along the axis of movement of the stop l3, subjected to a resilient action tending to maintain the tube H in contact with the stop I3.
  • This resilient action is generated by a spring [5 bearing against the body of the jlighter.
  • a cam l6 It will be understood that in a modification of the feed device described above, the metal tube II may be replaced by a'tube of any other material having a sufficient modulus of elasticity to allow of the resilient deformation of its walls at the crushing point I2 so as to'produce closure of the passage 9 and the re-establishment of communication between its upflow and downflow parts.
  • the device above described may be conceived in multiple ways and different forms of construction some of which by the natural resiliencyof the tube in its bent portions. When this resiliency proves insufficient, the ring I? may be held in contact with the stop 18 by the action of a spring.
  • the stop I9 is formed by a screw having an axial bore I9 providing a passage for the tube II and screwed into the upper wall 20 of the body .I of the lighter.
  • the cover carries a pusher 2.1 adapted to act, durin the closing of-the cover, on the end of the tube II and to push it back.
  • adjusting stop IBit is possible for the user to adjust the free cross sectional area in the bendsformed by the tube :1 and thus to adjust the .deliveryof fuel feeding the flame of the lighter.' f
  • a stationary support 22 which, on closing the cover, acts on the free end of the lever 24 so as to move the stop 23 in 4 of the sleeve He is pressed against a stationary support 22 by a stop 23 adjustable in position.
  • the latter is secured to the end of one of the arms of a double armed lever 24 pivoted on a stationary pivot 25.
  • An adjusting screw 26 permits of modifyin the position of the stop 23 relativelyto the stationary support 22 and thus ;modifying the cross sectional area of the passage 9 at the point of crushing of the sleeve produced
  • the cover carries a cam I5 the direction of the support 22 by an amount sufilcient to produce such a deformation of the sleeve I I0 that the inner walls of the latter come into contact with one another and close the passage 9 completely.
  • passage 9 is formed by two sections of rigid tubing, of whichone forms the upfiow IfIa and the other the downflow IIb, connected together by a flexible andresilient sleeve I Ic. nportion tion of the device shown in Fig. 5 is provided for supplying the flame with a liquid fuel at the normal temperature ofthe chamber and at atmospheric pressure, the passage 9 has a capillary element 26' passing completely therethrough and dipping into the reserve of liquid fuel and assuring the supply to the flame by capillarity. The capillary element 26 is thus more or less compressed at the point of crushing according to the value of the thrust applied by the stop 23.
  • the passage 9 is formed by a tube II twisted upon itself in the form ofa helix.
  • the upper end of this tube carries a toothed flange 21 gearing with a tangential screw or worm 28.
  • the latter is guided in guides 29, 39 in which it can slide and turn.
  • the free end of this screw is mounted a nut 3
  • the other end of the rod is hinged to the cover 2.
  • the user can twist the tube I I more or less about itself and in consequence produce the resilient deformations of its walls which modify the free cross sectional area of the passage 9 and thus adjust the feed-of fuel .to the flame.
  • the rod 32 presses the tangent screw 28 towards the right of the drawing, said screw, in the manner of a rack, imparting to the toothed wheel 21 a movement of rotation in a clockwise direction.
  • This rotation of the toothed wheel 2! produces a torsion of the tube II about itsaxis whereby its opposite internal walls comeinto contact and thus produce a fluidtight closure of the passage9.
  • the tube may be provided with an upfiow section Ila secured rigidly to the reservoir 8 a rigid down'flow section I II) to which the toothed wheel 21 is secured and an intermediate section IIc of pliant and flexible material such as rubber, which alone is subjected to deformation bytorsion.
  • the passage'9 may-be formed by a tube made in a single metal piece which is twisted spirally in its central portion.
  • the fuel reservoir 8 is provided, fixed rigidly thereto in a fluidtight manner, with a tube 33 sliding on'a rod 34 secured rigidly to the bottom of the reservoirS.
  • the rod '34 is of a diameter smaller than the internal diameter of the tube 33 so as to provide *anannular passage 35.
  • A'plastoresilient element 36 placed into the'tube 33' rests on the end'of the'rod 34 and is applied to this by a piston 31 carried by a hollow piston rod'38, guided inan axial bore I9 of a screw I8'-screwed into the wall 29 of the body I and forming astop for a ring I1 secured rigidly to the piston rod.
  • the cover not shown but assumed to be in the closed position, carries a pusher 2
  • the thrust applied by the piston 31 on the element 36 produces a swelling of the latter in such a manner that the peripheral wall comes into contact with the inner wall of the tube 33.
  • the piston is also provided with bores 39, 49 connecting the empty interior of the piston rod 39 to the empty exterior of the tube 33 in the downfiow of the element 36.
  • a fiuidtight joint 4 I formed by a sleeve connecting the tube 33 to the rod 38 opposes the escape of the fuel.
  • the reservoir 8 carries a hollow element 42 closed at its free end and having two parts, one 43 of large external diameter and the other 44 of small external diameter, separated by a shoulder 48.
  • the part 44 is provided with radial holes 45 normally closed by a sleeve 46 of plasto-resilient material mounted tightly on the part 44.
  • a tube 49 sliding on the part 43 has an internal collar 4! bearing against the sleeve 46 which is thus tightened between the collar 41 and the shoulder 48.
  • the device may be provided with a stop, adjustable in position, defining the axial position of the tube 49 when the cover of the lighter is in the open position.
  • the'tube I l is crushed locally at l 2 in such a manner that the natural resiliency of the walls tends to close the passage 9 completely.
  • a needle 50 placed into this passage and movable along the axis of the latter enables the walls of the tube to be spaced apart at the crushed point and thus establish communication between the upflow and downflow parts of this.
  • the cross sectional area at the point of. the crushing I2 is larger or smaller. Adjusting this axial position the user thus has the possibility of adjusting the supply of fuel.
  • a lighter comprising, a casing, wall means in the casing and forming a tank holding fuel under pressure, a deformable fuel tube having its inlet in the tank and including a portion having a passage of lesser transverse area than the area of the remaining tube portion, igniting means in the casing in combustion proximity to the outlet end of the tube, adjustable means initially deforming the tube by bending to provide in same the portion of lesser passage area, cover means movable to and from a position covering the outlet end of the tube and the igniting means and means operable by the cover means and deforming the tube to close said tube passage portion of lesser area.
