ARGAND GAS-BURNER.

Specification of Letters Patent No. 8,437, dated October 14, 1851.

To all whom it may concern:

Be it known that I, JOHN G. IVEBB, of IVilliamsburg, Kings county, State of New York, lamp manufacturer, have invented, made, and applied to use certain new and useful improvements in Argand burners, for

- the ordinary Carbureted Hydrogen or other similar gas by the application of a cone for the purpose of regulating the outer draft and deflecting the flame, for which I seek Letters Patent of the United States; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawing, making part of this specification, wherein Figure l, is a plan with the button removed and Fig. 2, is a section of my improved burner.

The like marks of reference apply to the same parts in both figures.

In these a, is a pipe conveying the proper supply of gas and on the end of this tube is a plate 6, either preforated with holes or made with arms that carry a ring flanch which supports the chimney or glass 0, and the short pipe 1, on the end of the tube a, receives a hollow yoke (Z, that carries the perforated Argand burner e, and supplies gas to the same and from the center of the yoke (Z, is the stem of a button f. These parts so far are made nearly the same as in my patent of 7 Aug. 1849 for a self generating Argand gas burner but I use this for the burning of gas that has been generated by other means and conveyed in pipes or tubes to the burner and I also place a cone 9, around the .burner 6, extending down to and supported by, or made with the plate 6. This cone is contracted till it comes near the lower edge of the burner and the upper part is parallel or may be slightly flaring out so as to be nearest the bottom of the burner, e. In the plate Z), are holes 2, or

an annular opening around through the plate between the cone 9, and chimney c. The burner 6, may be a tube with holes to pass out the gas which produces the same effect as the one shown, or a narrow slit may be cut around the burner to pass the gas out instead of the holes, or the burner may be made as a double cylinder of any required depth with the openings for the gas on the top as before.

Having thus described the construction,

the operation and effect is as follows: The gas passing from the pipe (6, through the yoke d, enters the burner c, and issues through the holes in the top of the same where it is to be lighted. The draft now passing up through the cone 9, a portion enters inside the burner e, and another portion passes outside the burner 6, between that and the cone 9, which it will be seen is but a narrow annular opening from the bottom of the burner to the top this supplies the proper amount of air at the base of the flame for the purpose of brightening it, but is not sufficient to overcome or prevent the inner draft as it passes up being deflected by the button f, and spreading the flame in a large semi-globular form, and the further supply of air outside the cone by the holes 2, completes the combustion on the outside of the flame, and prevents smoke.

It will be seen that the main improvement is the introduction of the cone to an ordinary Argand burner for although Argand burners have been used for gas, the light is not steady as will be evinced by the removal of the cone, the flame immediately flickering and becoming unsteady, the cone in mine concentrating the draft,-and by being rather close to the burner 0, also brightens the light very importantly, by supplying the proper amount to the outside of the flame at its base.

I am aware that a burner has been pat entecl covering a long expansive chamber to contain the gas to be burned, but in my burner the ordinary Argand burner is used, which is public property; and the patent before referred to covers a bell shaped mouth formed by the lower end of the gas chamber or burner, .but in my improvement no such bell shaped mouth is used, and I use a cone which I am not aware has ever been used wit-h any other Argand hydrogen gas burner and although a cone has been used with a circular wick burner it will be seen that the Argand carbonated hydrogen gas burner is entirely different both in the material burned and in the construction of the parts.

Therefore I do not mean to limit myself to the precise shape of the yoke or to the proportions or size. of the parts as these must be varied according to the amount of draft required for different qualities of hydrogen gas, neither do I mean to limit my self to the shape of the burner as long as the Argand principle of the inner and outer draft is maintained, and though I have described the cone as contracted at the base of the burner and slightly larger near the flame as the best arrangement I have found in practice yet some qualities of carbureted hydrogen gas or a difference of pressure in the supply may require the cone to be parallel to the top or contracted at the top. I therefore do not limit myself to the exact form shown at the top of the cone because the variations thus stated are merely practical and contingent While the main features of the application described remain substantially the same as set forth.

I therefore claim- The construction and use of an Argand burner and button With a cone to regulate a supply of air to the base of the flame in combination With an outside draft between the cone and a suitable glass chimney to complete the combustion and turn the flame over the button such parts being applied to burning carbureted hydrogen or similar gas, substantially as described and shown.
