HIS RIGHT TO B. G. BU

GAS-REGULATING BURNER.

SPECIFICATION forming part of Letters Patent No. 229,409, dated June 29, 1880.

Application filed April 17, 1880. (No model.)

To all whom it may concern Beit known that I, GEORGE J. HICKEY, a citizen of the United States,`residing at Waterloo, in the county of Black` Hawk and State of Iowa, have invented certain new and useful Improvements in Gas-Burners; and I do hereby decla-re the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usev the saine, reference being had to the. accompanying drawings, and to letters of reference marked thereon, said drawings forming part of this speciiication, and in which- Figure l is a side elevation of the attachment; Fig. 2, a cross-section, showing the4 same closed 5 Fig. 3, a like section, showing the same Open; Fig. 4, a bottom view of the upper cup, and Fig. 5 a top view of the lower cup.

My invention relates to gas burners for street-lamps and other uses, in which the llame is completely extinguished when the pressure in the gas-main is reduced, and the gas is not allowed to issue from the tip until the controlling-valve is moved by other means than the flow of the gas 5 and it consists in the construction and combination of parts hereinafter particularly described, and then specifically pointed out in the claim. t In the accompanying drawings, the letterA indicates a cup provided with a tube, B, which extends some distance up into the cup, and is connected at the lower end to the gas-supply plpe.

Into the cup A there is placed an inverted cup, O. This cup C is preferably made with an upturned iiange, a, which leaves an airspace between the side of the cup and the iiange; and it is further provided, at or near its center, with a downwardlyprojecting tube, D, which is closed at the top and adapted to fit loosely over the tube B of cup A. The cup C is further provided on its top with a chamber, E, in the top of which is fitted the burnertip F. This chamber E communicates with the interior of cup G through small apertures b, formedy in the top of the cup near the tube D. Springs G are soldered or otherwise secured to cup A, and extend some distance above its top, and admit of being sprung to one side, so that cup C may be easilyinserted in or withdrawn from cup A, while at other times they keep cup O within cup A, and yet extend far enough above the cup to allow the inverted cup to have a vertical play suflicient for the purpose hereinafter set forth.

The cup O is fitted in cup A so as to move therein with little or no friction and so as to completely cover the mercury contained in cup A, thereby effectually excluding dust and water and other matters that have a tendency to interfere with the satisfactory working of the parts; and within cup A there is placed mercury, glycerine, or other non-freezing and non-combustible fluid, and the function thereof is to effect a seat between the two cups, so as to prevent the gas from escaping between the two cups attheir junction, and also between tubes B and D, until tube D is raised above the surface of the lluid.

The quantity of the liquid in the cup A is .such as to allow the open mouth of tube D to be above the same when the cup O is raised sufficiently for that purpose, the springs G being arranged so as to allow cup G to be raised some distance without the springs exerting a pressure thereon as at all times to close the communication between tube B and the outside of tube D.

The burner constructed as describ plied to the end of th street-lamp or other li ed is apf e gas-supply pipe in a ghter, and Operates, as I shall now describe, to automatically shut off the iiow of. gas, and thereby completely extinguish the iiame.

It is Well known that the the mains is much less in th night, the works.

Now, when it is desired to turn on the gas at the burner, so that it may be lighted, the lamp-lighter raises the cup C until the tube D is lifted above the surface of the fluid in cup A, which is determined by the gas issuing from theburner-tip. As soon as that is done the gas flows first into tube D, and from thence into the space between the two cups A and C, and thence out, through the perforations in the top of cup C, to the burner-tip. The gas filling the space between the two cups A and O exerts a pressure on a surface large pressure of gas in e day-time than at pressure being reduced at the gas- IOO enough to hold up the cup C, so as to leave a space between the endfof tube D and the surface of the liquid in cup A. for the passage of gas from the supply to the burner-tip, and so continues to do until the pressure in the main is reduced sufficiently at the gas-works as to cause the pressure between the two cups to be so much less than the weight of cup C that the latter will fall until the end of tube D will enter the liquid in cup A, thereby cutting o all tlow of gas from the supply to the burner-tip, and completely extinguishing the flame. If the pressure of the gas be now increased it can only exert it-selt' on the small surface embraced within the tube D, and the pressure on that surface is not sufticient to overcome the weight of cup C; consequently the gas remains cut oil' from the burner until the lamp-lighter comes along and raises cup C, so as to allow the gas to till the space between the two cups and thereby exert its pressure on an increased area sufficient to overcome the weight of cup C, and thereby hold up the same and allow the gas to iow to the burner-tip until the pressure in the main is reduced.

It will thus he seen that the burner is selfextin guishin g and operates automatically; that it dispenses with the services of a man to go around and extinguish the gas-lights, as is now the case, and that it eieetually prevents any gas being consumed or escaping except when it is actually necessary to be used, in all of which there is effected a great saving to municipal corporations.

The device is exceedingly simple in con struction, cheap of manufacture, not liable to get out of repair, neat in appearance, and can be applied to any of the gas-fixtures in use without expensive alterations in the same for that purpose.

Having described my invention, what I claim is The cup A, provided with tube B and springs G, in combination with inverted cup C, provided with burner-tip and tube D, the parts arranged to operate as set forth.

GEORGE J. HIGKEY.
