Many gas-stoves heve e numimr of burn era, a common ment of gas ing that where fohr burnors sresrrenged at corners of n square or 'reetenglerevious to our invent on the mode employed of igniting gee-stove sinm tathese consisted in a seps'rate ignite; or pilot-light for each burner in ju xtapoeition to the burners, the. severel Igmters be: ing controlled simultaneously or se Such en em e'n't as. vantage thatfthere are our-flames constantly burnemgpnt of nire more no subject to more leakage than one burner.

Our novel dng a-smgle 1 distlnw being itself ignited by a idea. which we have carried out present invention, consists in dispositer centrally of the group m the burners, this igniter single pilot-flame d on to throw long and arranged when turne {as of flame toward the several burners,

It will be obvious that the vertical po- 'sition of the pilot-light may be readily edment. 3 s The pilotrfisme 7' is not sufiicient, by itself to ignite the four igniting-fats, or at least to ignite them immediately, because-they not spread and are se srate'd fr 1h one-en other by'too great a thpr errangements beprovided, a loss of with eccompenym inconveniences f 0 ts. To the end of pro an immediate,

this feature is notan tiel 105 however, thet to thelprineiple'of our invention, as other mesns may be adopted of efiectingt fourbn rners b', which mg beoif eny as 7 9 In branch-sup 1y .pipe (I, such yjarrenged, indiv dual 'regnlet- 60 substanre shown esim- 65 fur- 'ter'is-incloeedst top and same a proximity to the pilot-flame j.

To further hasten ignition, we may form four small leak-holes r in the sides of the igniter-head below the jets i and in radial planes midway between them and in closer As soon as the valve h is turned on, gas escapes through these holes, all ofwhich is caught within the bell and produces a gaseous mixture sufliciently rich to be ignited immediately by the pilot-flame and thereby also ignites the igniting-jets. The length and strength of the igniting-jets may be regulated by a needle-valve consisting of a screw 8 mounted in the side of the igniter-head below the leak-holes 1'.

lVe have found the bell 0 is a very advantageous arrangement for several'reasons...

It of course screens the pilot-flame from air currents "and prevents it frombeing blown out. The ignition, besides being per-.

formed promptly causes all the escaped gas to beburned and thereby'prevents a dis agreeable smellf'while the issuing of the jets through the holes g creates a draft which carries out all the products of come bustion and thereby assures the maintenance of the flame 7', which, unless such products were promptly removed, would go out in many cases. Moreover, a constant and adequate quantity of oxygen is at all times conveyed to the pilot-flame by its own natural draft up through the bottomofthe bell as indicated by the arrows, and out through the holes 9. In fact we have found that unless a bell, chimney or like device is used to surround the pilot-light with a supply of oxygen from alower stratum than the burners, the pilot-light will, after the burners have been burning for a time, invariably go out, being apparently extinguished. or choked by products of combustion from the burners which surround the pilot-light.

Having thus described our invention, What we claim as new and desire to secure by Letters Patent is:

l. The combination of a gas-stove having a plurality of burners, an igniter-head mounted at a distance from said burners, said igniter-head having a plurality of apertures through which jets of flame are adapt edto be sent to the respectii e burners, means for controlling the gas-supply to said igniter-head, said head having in addition one or more supplementary apertures or leak-holes adapted to develop an inflammable gas-mixture surrounding it, and a single pilot-light adapted to ignite said gasmixture and thereby all of said jets.

In combination with a gas-stove having a plurality of burners, an igniter located separate burners, an igniter therefor comprising a head disposed at a distance thereat a distance from said burners and having a plurality of apertures directed toward the several burners the igniter head having a" lurality of lea holes, and a valve controlin the flow of gas through said igniter sai apertures being adapted when sai valve is turned on to project flame-jets fromsaid i 'ter to the burners, and means being provig d for insuring the maintenance of a. constant small flame ator near said aper- 9, In combination with a gasstove having a lurality of burners, an igniter located at a istance from said burners and having a pluralit of apertures directed toward the several "urners, the igniter head having a plurality of leak holes, a valve controllm the flow of gas through said igniter, sai apertures being adapted when said valve is turnedon to project flame-jets from said igniter to the burners, a single pilot-1i ht located near said apertures, and meansor distributing the flame from the pilot-light to the severaljets when said valve is turned on.

' dially and means for supplying a single constantly burning flame with gas, said flame-being disposed so as to ignite said jets whenever said valve is turned on. v 4

11. In combination with a plurality of rom with said burners situated in diiferent radial directions from said head, said head having a plurality of apertures directed radially toward the several respective burners and ada ted to project long ets of'flame rarom said head tothe. respective burners, said head having leak holes below said jets; a gas-supply for said head, a constantly burning pilot-light at a distance from said apertures, and means for momentarily creatm an inflammable gas-mixture in the space I tween said light and apertures whereby the flame is conveyed from said light to said apertures.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
