Definitions

  • lighters that have a spark producing mechanism are those that generate same by means of a piezoelectric mechanism operated by impact, an operation combined with the opening of the gas outlet valve.
  • Said mechanisms based on a piezoelectric are totally different from those commonly used, in which the spark is produced by friction between a corrugated or superficially ribbed wheel, that constitutes a rotory rasp, against a stone or flint stretched by a spring against same.
  • the last two mechanisms are operated by a wheel or pair of knurled wheels fixed with that operating on the flint by direct action on the latter, or by a mechanism based on levers and/or cams, complete with accessory springs, that respond to the displacement of an outer hand operated lever, combined with a cap covering the wick.
  • Said spark producing means are not easily combined with the gas outlet valve of the wick, which in this case is operated by lifting the cap to uncover the wick or by means of a lever placed adjacent to the operation run of the spark wheel to permit the substantially simultaneous movement of both.
  • the invention obtains a new combination of means that permits opening of the gas outlet valve and rotating the rasp which produces the ignition spark in an automatic and simultaneous manner in response to manual pressure on a key or button.
  • One of the most important advantages of the invention is constituted by a device automatically operated by a key or button that produces the simultaneous outlet of gas and the spark to ignite same, which maintains the flame while the key or button is depressed.
  • Another advantage is the simplicity of the operating device, in which the actuating member for rotating the ignition wheel eliminates the need of using a dentation on same in the manner of ajack or sprocket to displace same by means of a lever, as said actuating member is displaced by a combined movement of axial translation and rotation in the operative stage, said rotation causing friction of the stone or flint.
  • the actuating key or button which is supplied with retention means in its assembly position to prevent same from escaping in the return run, has a direct line displacement in response to manual pressure on same, said dispacement is guided in the housing on elastic supports distributed in such a manner that they insure the efficiency of its operation.
  • FIG. 1 is an elevation view of the lighter of the invention with its case or housing partially cross-sectioned to show the characteristics of its operating device.
  • FIG. 2 is an elevation view of the piece that constitutes the operating member of the rotory rasp or ignition wheel.
  • FIG. 3 is a top plan view of the operating member il' lustrated in the previous figure.
  • FIG. 4 is a plan view of the operating piece that works with the operating member in which its projecting elastic portions that operate as jacks are shown.
  • FIG. 5 is a similar enlarged view of FIG. 1, in which a section view of the operating mechanism and the valve is shown to appreciate the arrangement of same;
  • FIG. 6 is a transverse sectional view of the lighter taken along the line VIVI of FIG. 5.
  • the lighter of the invention includes a case a that conforms a deposit or reservoir 1 containing the fuel charge (liquefied gas) that is closed at the bottom 2 which, in the case ofa disposable lighter, can be welded or sealed. or have an adequate valve that permits recharging said deposit 1.
  • the fuel charge liquefied gas
  • the side opposite to said bottom 2 constitutes the housing of the operating device b and valve 0 both arranged on the inner wall 3 that encloses said deposit I.
  • Said inner wall 3 forms a seat 4 of the device b and one 5 of valve c, the latter having an outlet 6 for the fuel passage.
  • a stud or boss 7 projects upward, providing an axle substantially parallel to the wall of housing a, that defines a cavity between the wall and stud in which the end wall 8 of the key or button 9 for operating the assembly can be received; said wall of housing a has an inner depression 10 in which extension 11 of said end wall 8 is displaceably disposed. Said extension 11 limits the return travel of button or key 9.
  • the spring 12, that constitutes the return means of button 9, is arranged between stud 7 and a well 13 projecting from the inner wall of said key or button 9.
  • the aforesaid button 9 covers one part of the end portion of housing a, and is similar to hollow piece 14 that covers the ignition chamber and defines opening 15 of the flame passage.
  • an extension 19 projects downwards within housing 0, whose terminal rests on the power arm of lever 20, said lever being of the first kind with its opposite forked arm 20' constituting the opening means of valve 0.
  • Shaft member 22 is formed from a rod whose upper portion has a pair of longitudinal grooves 24 guiding its axial displacement, while the lower portion has threads 25 that determine its angular displacement about its center line.
  • Shaft 22 is coaxially and internally mounted on bearing 26 in whose upper part the shaft rotates.
  • the ignition wheel 18 is solidly fixed on the outer face of the bearing 26 at its upper end.
  • the inner surface of said bearing 26 has formed, diametrically opposed, rib-like projections 26 (FIG. 6) on which the longitudinal grooves 24 of shaft 22 are slidably mounted.
  • the lower inner portion of said bearing 26 forms a cavity with play in which the lower threaded portion of said shaft 22 is freely housed, Shaft threads 25 may be observed in FIG. 5.
  • the lower end of said shaft member 22 is inserted in the hollow threaded sleeve 27, supported on seat 4 of the inner wall 3 below bearing 26.
  • the threads of said sleeve work with threads 25 of shaft 22.
  • sleeve 27 has a widened portion 28 that rests against an annular step in wall 3, said portion having curved fingers or extensions (FIG. 4) that operate as stops, that is to say, they permit the rotation of sleeve 27 in only one direction and, in the opposite direction, their ends drive in against projections of the housing wall, like a ratchet.
  • coil spring 30 is disposed about said member and assists in the return movement of button 9 and member 22.
  • Valve c corresponds to known designs. Same is formed by an externally-threaded principal body 31 disposed on seat of the inner wall 3 (FIG. 5), with a gasket 32 and a flame regulator 33 on the upper part whose operating lever 33' projects towards the outer part of housing a.
  • valve 0 carries axiallydisposed hollow rod 34 that forms the gas outlet spout. Fixed on the upper terminal of said rod 34 is a washer or shoulder 35 under which the forked arm of lever 20 operates.
  • the opposite end of said rod 34 is supported on the outlet opening 6 of the fuel deposit 1.
  • Spring 37 urges rod 34 downwardly which maintains said opening 6 closed by seal 36.
  • the rod portion 34 housed within body 31 has at least one lateral bore 38.
  • member 22 can slide only axially with respect 0 bearing 26, the latter having its inner projections 26' n the longitudinal grooves 24 of the former, said bearng 26 turns with said member 22 and the ignition vheel l8, outwardly fixed on piece 26, rotates to scrape on flint l6, generating the spark above the gas outlet tube 34 of valve 0.
  • valve 0 opens, igniting the gas in said outlet spout of rod 34, the flame of same rising through opening 15 of cover 14.
  • valve 0 Said simultaneous opening of valve 0 is produced by the thrust of extension 19 of the inner wall under force of the button 9 which, by displacing lever 20, lifts tube 34 with its forked end 20' by means of shoulder 35.
  • the raising of said tube 34 dislodges the seal 36 from its seat, the gas passes through opening 6 outside said tube 34, laterally enters same through bore 38 and goes out through the spout formed beneath the flint l6 and wheel 18 assembly that originate the spark.
  • Simultaneously button 9 raises shaft member 22 whose lower portion is threaded on sleeve 27 of which portion 28 forms the ratchet or stop means.
  • the ascen sion of said member 22, axially slidable with respect to bearing 26 on which the ignition wheel 18 is fixed, is effected without said member rotating, as in this return displacement sleeve 27 rotates in its housing (in an opposite direction to that of ratchet fingers 29), which permits member 22 to be displaced in a rectilinear di rection on guides 26' of bearing 26 while the latter and wheel 18 remain fixed, assisted by the braking effect through the support of flint 16.
  • the return of the button or key 9 has as security limit the support of extension 11 against the upper edge of cavity 10 in which it is housed.
  • a lighter comprising a case forming a fuel reservoir having an outlet adjacent a spark producing means
  • the improvement comprising a shaft mounted for rotation and axial movement within said case and having external threads on its inner end, a spark producing rasp wheel coupled to said shaft but axially movable with respect thereto, means for rotating said shaft and rasp wheel when said shaft is moved in one axial direc tion and for preventing rotation as the shaft moves in the other axial direction
  • said means comprising an internally threaded sleeve freely rotatable in said case wall and surrounding said shaft, with said threads engaged with the threads on said shaft to rotate said shaft and wheel, ratchet means on the outside of said sleeve cooperating with the wall of said case to prevent rotation of the sleeve when force is applied to said shaft in said one axial direction and to permit rotation of the sleeve when force is applied to said shaft in said other axial direction.
  • the lighter of claim 1 which includes a reciprocatable operating button mounted on said case in contact with the outer end of said shaft for applying axial force thereto, a valve in said outlet, and means connecting said button and said valve to open the valve when the button is moved in said one axial direction and to close disposed above said sleeve, the inner surface of which is keyed to said shaft to cause the bearing to rotate with the shaft while permitting axial movement on the shaft, said rasp wheel being locked to the outer surface of said bearing.
