fh if 'i/.ihua it muy confront i ,il lane, a cito 'Jen olf theellvnited States, and reaident oi i' ilwanhtc 'in 'the cminty olE Milwaukee and i irri comin, have invented certain new nel no .nl Alntprogements in lgnitern; nml lio l celos declara.: that the tollowingis 't ln el ici:Yloacription thereof. t ol' myinfenlion iss lo 'tive and ccononlically iter rolf a group ol' gigas burnlie it linnn/n that l, Knr D. t

olfect ot my `invent-ion is to n: inttanii-ttently Supplying.: l ras reairvfir cf'iincident to uniti-i y clnirtgo of gas to a troni the tiring; rents l. of in y invention in to l reservoir' with a sonicai hottoin pl not which the torch-- llania is dir" w'ncrchy the .f-iaiil tra:w reservoir is marin ainefl at a hicjh tommalla-c, while at the-same time they conical plug serve-s as t lflellector 4for spreading: the torch-- flame radially to eti'ect perfect ignition ol' the gas escapiiiur tronrthe tiring' venta, it beI ing obi/ione that the "heated t-.hanibcr or PTU l tl :reservoir will Serve to expand the gases therein .to vinlcelcratc their f linchargc into fine jetlile flames.

Another object of my invention iS to pro vide a manually controlled valve for supplying gas to the reservoir and simultane onsly supplying an auxiliary flow of gras to the, torch, which torch is also constantly supplied With gas through the valve casing from a header or main pipe.

With the above and other minor objects in View the invention coneists in certain peculiarities of construction and Combination oit' parte as hereinafter set forth with reference to the accfmipanying illustrations and subsequently claimed.

In the drawings Figure l represents an elevation ot an igniter enilmdyingr the leatures oi my invention, with parts broken away and parte: in section to more clearly illustrate details of construction, and lliag. 2, a detailed sectional plan 'view of the torch head, the section being indicated hy lino 2W@ of Fig. l.

Referring hy characters; to the drawing-ga, l represents a gas main harina' ii'ttelfl thereto a Nahe-easing 2, the same being provided with a duct lthat leads to the bottom ol a well l, which well has threaded therein a Montolieu 5. The bottom ol the shell 5 is conirally 'laced to l'ornl a month 'for a gas cavity (i, which cavity is normally closed by a valve member Y, the tapered head ol? the :same being adapted to engage the conical faced month. When the valrc member is seated it also .serves as a closure for a duct S that leads toan annular recess l" lornied in the face of tlie,.}'ili1g-sliell 5. This annu,- lar `revest 8 uturn cmnxnunicatcs with a maincupply duct 8,.whieh duct communicates with a itorehftube S) harina' its` cull tapped into the valve-canina'. The main 1111- ply dart 8" is constantlyled with aat troni a ily-,nass duct 'l0 that leads from the bot-` tom ot' the well il, thcrsaill by-paas duct bcinn' regulated hy a valveniember l0 in the l'orlnol' a pointed selfscrew, which sct-screw and is adapted to restrict or increase the con` etant llow of gas .from the main l to thc torch lube ll. ,lhc plug-shell is also provided with a second annular recess 1l that is connected to the gas cavity l b ytports l1. ,lho annular recess 1l also connnunicates with a channel 'l2 that is Vformed in the valr'ocasing, which channel, iu turn, co1nmunir-ales witl an end of a feed-pipe '13, the saillpipc heine;{in .threzuleil union with thc valve-casing and,` as Shown, also in cases thc torch-tube l).

The valve member 7 has a stem 7 which extends through. the bore of the plug-shell and into a honnet portion 5 thereof, at the bane olE which bonnet portion the stein is lifted with a soft. gasket 14, constituting a packing, whereby gas is confined within the shell cavity. 'lhe valve-stem terminates with a puslrbulton having a neck that is in telescopic engagement with the bonnet rarity and interposed between the button neck and gasket is a coiled spring 16, which coiled spring: serves to hold the valve ineinller in engagement with its conical seat,

trough a gan re in a. head ift, the reservoir of which head comnfniaicates with and is secure-d'1 to the outer end et the ,tcclil.ppe` The top por is in threaded union with the valve-casini,r ,1

whereby gas is checked from flowing into' tion of the head is sealed by an overhanging cap 17 and the bottom portion of said head is closed by a conical metal plug 18, which plug' constitutes a deflector. rlhe circular walls of the head are provided with radially disposed tiring vents 19, which vents correspond in l 'number to the burners grouped about the igniter, the vents beingso aliued as to cause a. jet llame to be discharged upon each burner ol the group when the valve u'mchaixism is operated.

The torch-tube 9, after passing through the l1ead,`is bent dowinvardly and its end is uplurned to form a. torch-tip 9, which tip centrally disposed with relation to the conical plug' 18. The torch-tip is protected by an open ended shield 20, which shield is suspended from the burner head by arms` 20 that are crimped or otherwise made last to the plug 1S. Thus currents of air are permitted to pass upwardly through the shield and are deflected outwardly from the upper end of said shield by the conical plug, whereby vertical stratus of air are maintained about the torch at all times and said torch isthereby guarded against transverse currents which would tend to eX- ting'uish the saine.

From the foregoing description it is apparent that a constant pilot light is inlin-y tained under the reservoir and to ignite any one or all of the stove burners the oper'- ator depresses the button l5, whereby the valve member will recede from its neat a ud establish communication between the gras main and gas cavity 6 of the plug `shell. The iull flow of gas from the main will thus be admitted to the gas reservoir 16 and simultaneously an auxiliary supply of gas will be delivered to the torch-tip 9@ whereby the said torch is flared to envelopthe firing ventsof the gas reservoir, causing-ignition of said gas, whereby a series of jet flames are emitted from the head directly upon all ot' the burners grouped about the igniter. Then pressure is removed from the button .15 the supply of gras to the reservoir 16 is immediately cut oil' and the constantly burning torch is reduced to a small flame.

I claim:

l. In an igniter for stove burners coinprisiug a Vented reservoir, a fecdpipe therefor, and a torch-tube having its tip disposed under the reservoir; the combination of means for supplying a constant flow of gas to the torch-tube, and valve-controlled means` for simultaneously supplying an increased flow of gas to said torch-tube and a full supply to the reservoir.

2.` An igniter 'For stove burners comprising a vented reservoir, a feed-pipe therefor, a torch-tube having itsl tip juxtaposing the reservoir, a valve-casing having a channel in communication with the reservoir feedpipe and a main supply duct in communication with the torch-tube, the main supply duct being' provided with a by-pass duct, a Valve for controlling the reservoir supply lpipe channel and torch-tube, and means for supplying` a constant flow of gas to the by -pass duct when the valve is closed.

la testimony that l claim the foregoing Yl have hereunto set my hand at Milwaukee in the county of Milwaukee and State of licentie in the presence of two witnesses.
