IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 152,568, dated June 30, 1874 application tiled May 15, 1874.

tions of modifications embodying the general principles of the same, with the outer cap removed. Fig. 4 is an interiorview of a moditication of a portion of the burner.

The object of the present invention is to direct and regulate the passage of, so as to economize, gas, to produce a Steady flame, and

prevent the whistling or disagreeable noise occasioned by the passage of gas through ordinary burners, and to ei't'ect these ends my improvements consist in a gas-burner constructed, arranged, and operating as I will now proceed to describe and point out in the claim.

In the drawing, A represents a base of a burner formed with a bottom interior screwsocket, a, to screw on a gas-pipe, and formed with a top shoulder' and screw-stein, b, to receive a burner-cap, B, formed as usual, or otherwise, and provided with a lava or other tip, O. A vertical aperture extends through the center of the stem b and base A, and is 'formed at the top with screw-threads to or shell, D, formed to screw, so as to be raised4 and lowered, on the tube or stem c, to admit the bottom of the shell or cap D being raised above or brought down upon a beveled or other seat formed on the top oi' the stem l), to lessen 0r increase the opening caused-by the rising of the cap or shell between the bottom of the cap or shell and its seat, andregulate the flow of gas, which passes up through` the central aperture of the tube or stem' c, out through' the orces d, or slots' d', and perforated disk or collar d, down between the tube c` and cap or shell D, and ont through the opening between -the bottom of the shell D and seat or top of stem b, into the outer cap B, from which it linds an exit through the tip in the form of flame. Above the cap or shell D, as represented in Fig. 1, is a check nnt or cap, f, that turns on the top of the tube, c, and bears upon the top of the cap or shell D, to regulate it and hold itin position to admit the desired flow of gas; or the cap or shell D may have a solid top, as shown in Figs. 2 and 3, to form a cap for the tube c, whose central aperture may be readily freed of obstructions by removing the cap and blowing through the tube; and for this purpose, besides its other functions, the nut or cap j' is preferable, for it may be readily removed to open the end oi' the tube o 'without disturbing the shell or cap D, when adjusted to admit the flow of gas desired.

The bottom of the inner periphery of the shell or cap D is beveled or otherwise formed to incline the passage between it a-nd the beveled or other formed seat of the base, and may, if desired, be notched out on the bottom, as shown in Fig. 4, or otherwise constructed to form a passage or passages for the escape of gas between it and its seat.

By the above description, reference being had to the drawings, it will be readily seen, without further explanation, that the gas pass ing up the tube c, through its orices d, and then down between it and the shell D, enters, through the passage between the shell and seat, the outer cap with less impetuosity than when admitted therein as ordinarily, thus producing an even ilow of gas without the disagreeable noise ordinari] y produced by the direct and sudden inux of gas into the burner. It will be also seen that the flow ot' gas is' readily regulated as desired by raising orlowering the cap or shell D by turning it on the stem or tube c, and enlarging or diminishing the passage between the bottom of the cap or shell and the seat, thus using the amount of gas required to produce the desired flame and preventing` the waste of gas usuel in ordinaryv burners.

Having thus described my mpro\'ements, what I claim its 1n y invention, and desire to have secured to me by Letters Patent, is-

In e gas-burner the Combination ot the per-- forzt'ted screw-stem or tube c, base A, cap or s110111), oep-nut f, and burner-cap B, all :tr-

rnnged and operating substantially ns mid for the purpose set forth.

In testimony whereof I have signed my nznne to this specification in the presence of' two subsoribin Witnesses.
