PATENT OFFICE.

.To all, whom; tima/y concern.;

Be it known lthat I, PETER KELLER,- a'citizen of the United States, residing at Chicago, in the county ofCookand State of Illinois,

' have invented certain Improvements in Gasy Burners, of which the following is a specification.

. This invention relates to certain improve-- ments in gas-burners, and hasforitsobject to `provide for use. in such burners means for regulating and controlling the supply of gas to the burner tip, whereby amore even and uniform flame is produced notwithstanding tantadvantages are attained, and the device vcarefully"defined in the claims. l ""In the accompanying vdrawir`1gs,.whicl iV variations in gas-pressure at the service-pipe and whereby flickering of the flame at thetip is prevented when the gas-pressure is low- The invention consists incertain novel features of the construction, combination, r and arrangementof .the several parts of the. 'improved gasfburner, Vwhereby certain imporis renderedslmpler, cheaper, and .otherwise betterA ada ted" and more convenient for use,`

all as will t e hereinafter fullyset forth. rIhe novel features of the invention will be serve to illustrate my'invention, Figure. lis

Fig. Sisan ene larged sectional view. taken horizontally. through the pillar'v of the burner inthe plane indicatedby linea t in Fig. 1 and showing certain features of the inclosed controlling means, as ',willbe hereinafter explained; and.

y thefwall of said passageand upon seated thedownwardly-bentannular edge of l a screen"6,`formed, as herein shown, -offpere forated metal plate, although it may aswell be pro ducedif desired, vfrom metal gauze in a well-known way. I

The n controllingn and` regulatingmeans l are,

housed within the passage 4 beneath the screen `6 and comprise a lower-member.7,hav'.

ing an annularA vpendent flan e8r aroundr its outer lower part andv adapted. or snugengagementwithin the wallsof the pillar, which: arel usually slightly ta ered or coned, whereby it will be-understoo that by simply inserting lsaid' member7within the larger lower end .of

theV gas-passage 4 and pressing it. upward;

. therein. the eXteriorsurfaces of the flange: 8.

} may be tightly pressed within the walls of the tion. during use of the burner.

i vThelower'mernber 7 has-an integral cen-Ap tral nipple or seat 9 extended upwardly froml .fitscentral partand of lessdiameter than thev passageV 4, whereby an annularjspaceor cham- 5 berV is Vproduced within the pillar surrounding' said reduced nipple or seat, and 10 indicates .atgas-discharge port producedin the top of' the nipple or seat 9, said top being flattenedl i to produce a plane surface," as shown clearly linFigLl.- 11 represen-ts the upper movable member or element .of the controlling or regulating means,and this member is constructed in the lform of a cap or thimble .with-imperforate wallscomprising a top portion and a pendent skirt or edge flange, the diameter of which is midway between the diameters of the nip-ple;

itslower. edge whenthe cap'is in its lowermost position, as shown in Fig. 1, will be ele-;

pillar to hold said member securelyin posi- IOO vated above theV horizontal outer part. of the lower member 7 sufficientlylto permit free :and unobstructed. flow of gasibetween' the parts, Iso.V that. even that4 position .of the.

1 whereby the portions of the under surface of the cap or member beneath such corrugations are elevated out of contact with the ilat top face of the nipple 9 when the cap is in lowered position, radial gas vents or passages 13 being thus produced from the opening 10 in the nipple and leading outwardly for communication with the annular space between the pendent skirt of the cap and the side walls of the nipple 9, so that in such position of the parts gas will still be supplied from opening 10 in the nipple through said vents or channels 13 to the space between the members and may flow from said space beneath the under edge ofsaid pendent skirt and upwardly in the gas-passage 4 around the cap or member 11 to continuously supplythe flame at the tip.

By means of the elevated ridges or corrugations 12 12 in the top portion of the cap or member 11 of the device it will be seen that the remaining intervening portions of said top portion are caused to stand in a lower plane than the crests of said ridges or corrugations, as indicated at 14 in the drawings, and when the cap or member 11 is elevated above the nipple 9 by excessive pressure of the gas escaping at the opening 10 in the nipple the ridges or corrugations 12 will by contact with the under side of the screen 6 serve to hold the depressed portions 14 of the top of the cap or member 11 out of contact with said screen, so that a free ilow of gas is af- Jorded between said portions 14 and the under side of the screen, the gas so supplied escaping through the nterstices of the screen and being supplied in a continuous manner to the burner-tip above.

From the above description of my improvements it will be seen that the improved gas-burner is especially well adapted for use, by reason of the fact that the flow of gas through the passage to the burner is eiiectively regulated and controlled at all times and at the same time, even when the gas is llowing at theeXtreme low or high pressure, the cap or. movable member cannot seal either the opening 10 in nipple 9 or the interstices of the screen 6. In this way a remarkably steady and uniform flame is produced, and flickering, which has been a Jfault hereto- Jfore common in such devices, is altogether avoided.

It will also be obvious from the above description that the improved gas-burner constructed according to my invention is capable of considerable modication without material departure Jrom the principles and spirit of the invention, and for this reason I do not desire to be understood as limiting mysell` to the precise form and arrangement of the several parts of the device as herein set forth in carrying out my invention in practice; nor do I wish to be understood as limiting the application of my improvements to pillar-burners alone, since it is obvious that the device may be applied to burners of all descriptions wherein it may be desirable to regulate or control the supply of gas to be burned. For example, in Fig. 4 I have shown the application of my improvements to the base connection of a Bunsen burner, such as is used in Welsbach and other similar incandescent gaslamps. As herein shown, said member 1a has a hollow produced in it wherein the improved regulating and controlling means are located, the construction and arrangement being substantially similar to that above described.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination of a lower member having a central upwardly-extended nipple provided with a gasdischarge opening in its top and adapted for location in the gas-passage of a gas-burner or the likeand a cap having a top portion and a pendent edge flange of greater diameter than said nipple, the top portion of the cap being adapted to rest on the nipple and said edge flange of the cap being spaced from the sides of the nipple and having its lower edge adapted to stand out of' contact with the lower member in such position of IOO the cap and said top portion of the cap having vents adapted for communication with the gas-discharge opening of the nipple and leading outwardly into said space between the edge ilange of the cap and said nipple.

2. In a device of the character described,

the combination of a gas-burner or the like having a gas passage, a screen extended across said passage, a lower member having a pendent edge llange engaged in the gas-passage of the burner below said screen and having a central upwardly-extended nipple of less diameter than the gas-passage and provided with a gas-discharge opening in its top and a cap having a top portion and a pendent edge flange, the top portion of the cap being adapted to rest on the nipple and said pendent edge ilange being extended around the sides or the nipple and spaced therefrom and also `from the walls of the gas-p assage with its lower edge elevated out of contact with the said lower member to permit free ilow of gas between the parts, the top portion of the cap being corrugated to produce on its under side radial vents or channels leading from the gas- Adischarge opening ofthe nipple t the space In testimony whereof I have hereunto between the nipple and the edge flange of the signed :my name, at Chicago, Illinois, in the 1o Icap when said cap is lowered, the parts of presence of two subscribing witnesses, this `said top portion between the eorrugations 30th day of June, 1905.

5 forming depressions on the upper surface of PETER KELLER.l
