Definitions

  • This invention relates to a novel means and method for controlling the fiow of gas to the burner in lighters such as are used for lighting cigars and cigarettes and which utilize butane or other gas under pressure as fuel.
  • Fig. 1 is a side elevational view of a typical form of cigarette lighter in which the invention may be embodied.
  • Fig. 2 is an enlarged vertical sectional view through the burner portion of a lighter embodying the invention.
  • Fig. 3 is a view illustrating the method of inserting and adjusting the piece of porous metal for controlling the flow of gas in accordance with the invention.
  • Fig. 1 illustrates merely by way of example one well-known type of In order that I lighter in which the invention may be embodied.
  • the lighter as shown comprises a fuel chamber 10 for containing gas under pressure, for example butane.
  • the burner is indicated at 11.
  • the igniting mechanism may comprise a well-known type of spring-restored depressible fingerpiece 12, pyrophoric lighting means at 13 and a pivoted snufier 14 operatively connected and mounted on the top of the fuel receptacle, for example in the manner disclosed in the patent to Aronson No. 2,002,845.
  • FIG. 2 there is here shown in detail the construction of the novel valve and orificeassembly for the burner.
  • This may comprise a tubular internally threaded portion 18 secured in a wall of the fuel receptacle 10, the lower end of this part having a central bore 19 through which the gas may flow from a mass of cotton or the like 20 which surrounds a spring-like means 21 within the fuel receptacle, such spring-like means retaining the cotton away from the mouth of the bore 19 so that the latter will not become clogged with cotton or individual cotton strands.
  • a hollow plug 22 is threaded within the portion 18 and serves to retain in place a filter disc 23 through which the gas flows up to the burner, the filter serving normally to exclude from the burner and valve parts any foreign particles or fibers or the like which might otherwise pass up into and cause clogging of the valve parts.
  • An orifice piece 24 is threaded into the portion 18, these parts being sealed with respect to each other as by suitable packing 25.
  • the piece 24 is formed with a central opening 26 therethrough. This may be of a size which can be readily drilled without difficulty, for example of a diameter of 0.013 inch or larger.
  • the upper end of this hole is normally closed by a valve portion 2'] mounted on the lower end of the stem 15. It will be understood that normally the spring-pressed ball 16 in the snuifer 14 holds the valve stem down so that the valve portion 27 seals the opening 26, but when the snufier is raised, the gas pressure is sufiicient to raise the valve parts 15, 27, to the position shown in Fig. 2 whereby the gas is free to flow up through the opening 26 and then up along the parts 15 and 27 through a central opening 28 formed in the burner base 29.
  • the orifice piece 24 as initially formed has a bore, cavity or recess 30 formed at its lower side and into which the opening 26 communicates.
  • the recess 30 is adapted to receive the piece of porous metal above referred to and indicated at 31 in Figs. 2 and 3.
  • Suchporous metal may for example be formed of powdered or finely divided particles of bronze which have been sintered together in such manner that fine interconnected pores will remain distributed thcrethrough thereby providing a multitude of fine tortuous passages through which the gas may flow through the piece 31 up into the opening 26 and thence to the burner.
  • Metal of this type having fine interconnected pores is now readily available on the market with fine pores of various sizes.
  • the material used would be of the grade sold as being capable of excluding from its passages particles of about 0.0005 inch in diameter, although other grades may be used.
  • the piece 31 may conveniently be punched out of a sheet of such porous metal in a manner such that the piece will be immediately deposited in the cavity 30 of one of the orifice pieces 24.
  • the piece is then preferably secured in place and adjusted in the manner illustrated in Fig. 3.
  • a tubular tool as at 35 is preferably used having a rounded annular upper end surface portion as shown at 36 of slightly smaller diameter than the cavity 30.
  • V/hile the orifice piece 24 is suitably held in fixed position, the tool 35 is inserted as shown and by any suitable mechanical means is then gradually urged upwardly so that its upper annular rounded surface 36 presses against the piece 31 and causes the peripheral portions thereof to be pressed radially outwardly somewhat to provide a forced fit to permanently retain the piece 31 in place in the cavity 30 and in a position covering the intake end of the opening 26.
  • the channel 37 within the tool is preferably connected with a source of gas under pressure such as to be used in the lighter, and this gas consequently flows through the multitude of fine passages in the piece 31 up through the opening 26 so that the gas may be lighted to provide a test flame as indicated at 38.
  • a source of gas under pressure such as to be used in the lighter
  • the line passages therethrough will be sufficient in number and size to provide a flame much larger than would normally be desired for a lighter.
  • the passages through the piece 31 are so fine that troublesome foreign particles do not tend to enter, and are so numerous that even if a few of them should become clogged, the effect on the gas flow will not be adequate to noticeably alter the size of the flame.
  • the particles will be trapped by what may be referred to as depth filtration, as distinguished from the surface filtration effect obtainable by a screen and hence any such particles will not tend materially to alter the total etfective gas carrying capacity of the passages.
  • control orifice instead of limiting the control orifice to one tiny opening, for example of 0.0012 inch in diameter as heretofore, and which could easily become clogged, with the present invention there will be a multitude of almost microscopic openings distributed over a surface area of & inch in diameter for example. Thus the probability of any material clogging by fine foreign particles is very greatly reduced.
  • burner valves of lighters of the type here involved must be replaced by relatively unskilled employees in widely distributed service stores.
  • the orifice pieces as here disclosed containing the porous metal gas control means are particularly advantageous under these circumstances, since assurance can be had that the control passages will not be blocked by foreign particles, but will be in the same proper condition as when the parts left the factory.
  • a lighter construction having a reservoir for containing gaseous fuel under pressure
  • the combination comprising a burner valve mounted on a wall of said reservoir, a member mounted inwardly of such valve and having an orifice through which the gas may flow to the valve, a cavity communicating with said orifice and a mass of metal formed with fine interconnected pores located in said cavity and covering the inlet of such orifice, said mass of metal having a central portion containing a multitude of fine passages through which gas may flow to the valve, a depressed annular portion surrounding said central portion wherein the metal has been compressed so as to close the pores therein and an outer peripheral portion expanded by a swaging-like operation so as to grip firmly the walls of the cavity, the fine passage of said central portion having a predetermined total effective gas carrying capacity which is less than that of the orifice, whereby such passages will control the rate of flow of gas through the orifice to the burner.
  • a valve for shutting off and admitting the flow of gas to the burner, a member having an opening through which gas may flow to said valve, means for protecting said opening against clogging by foreign particles and for controlling the fiow of gas through the opening, such means comprising a body of metal covering the opening and formed with fine interconnected pores distributed therethrough, said body of metal having a central portion provided with a multitude of fine passages communicating with said opening and a depressed annular portion surrounding said central portion above and about which the porosity of the metal has been reduced, the total effective gas-carrying capacity of said fine passages controlling the rate of flow of the gas to the burner, and a filtering means through which the gas is conducted before entering said passages.
