f which the vfollowing is'a specification.

Thisiiivention relates io certaiutnew and stoves and its object is to provide a device the burners' of a stove has been lighted, will others, without the use of matches or other fire-producinv means. Vire. employ, to this end, a preferably horizontally disposed torch whiclniviiile connectedwith the `gasa convenientl1 located handle. and which.

liglitcd its fire may be `communicated to with its mouth first toward t ie lighted burner andsubsequently iiiA the direction of a. burner from which the gaseous tiuid arises prior to its ignition.l Y j An embodiment of oui invention is illus-r Figurc 1', represents a top-view of a gas tion, Fig. 9.a sectionV taken' along the line 2 2 Fig. l,l `ig.3,a' central longitudinal scc liii'v'ed scale. Fi' 4fk a similar View rshown g a i ing a modified construction and Fig. 5, e. fragmentary view showing an elevation of it is connected with the gas supply pipe.

Referring .to the diawiiigs,'let the refer`- ence character 2 designate a gas-stove, the burners 3 of which are disposed below the top-plate and separately connected by nieaiis of pipes with a header or manifold 6 which connects with the gassuppl y pipe?.

providcdniat'its upperv extremity, with a laterally projecting, exteriorly threadedstud 19 which connects with the correspondiuglyA threaded end of a tubular torch 13 the op.- posite 'extremity of which is litted with a 60 tip 14 'through vwhose aperture the gas i discharged. vThe plug 10 is rfurthermore an axial bore l5' which at its upper end, connects withtlie torch I3 by means of apassage 16 inthe stud'l, while` 65 its opposite loweriiiost ,extremity comniunicales with one-or more. transverse channels i7 terminating inan external auiiul; i' groove in the lower portion of the plu", `wliieh register-with ports 18 vin the surroiiiidii'igv 70 bearing il. The torch li.- is i thus continuously in communication with the interior of the housing S,Y irrespective of the position of the plug l0 which, it will be observed. is rotatable about. its vertical, lon- `V axis. A laterally projecting branch I9, formed integral with the housing v8., has an internal threadfor'the attachment, y.

of a conduit 20 which serves to convey the gaseous fluid from the supply into the. iii 80 tcrior of the'housiiig, and whichtio this end, communicates with al b v-pass 2l iii the branch 15.. The opposite extremity of the conduit 2G is connected witlr :i head pro- Vvided with a downwardly extending hollow bra noli bores, is revolubl)v mounted in the parts inv i which the)v areforined. The outer extremity of tliestei'ri 28, which protrudes beyond the 100' head Q2', is provided with a hand wheel 29` by manipulation of which t-lievstem-"is rctated, and it projects throu li a central ap-V erture iii a' screw cap 30 Wl ch is adjustiib 1 associated with the cylindrical portion Q25* 105 i ofthe head in which the stein. is mounted, to provide an impervious; joint in "cperation with an elastic washerl placed within the end of the said portion. The opposite end of the stem which 119 serves to control the flow of i ,-fojects into the interior kof the' housing carries one of 'a pair of coperativermiterlroars 32 and 33.the other oneof which is i mounted upon an extension '34 of thev plug li'i, which projects be ond the 'lower edge off fue bcarin 9. A coi ed 'spring 35 which enges the veled gear 33 and the head of a .ifi1t36 screwed into-the end of the extension fil, is provided to take up wear on the plug, and to consequently maintain the two gearwheels in operative engagement vWhiley washers 37 and 38 of hardened steel placedr between the gears and the adjacent surfaces of the head,'lessen the amount rof'wear o n the contacting kparts. The housin 8` is `closed at its lower end Yby means o a nut 39` and its upper surface isdish'ed for the rpurpose of collecting greasy substances thrown oil' by articles of food .while they are being prepared over the burners of thestove, andr conveying them asa lubricant, to

the rotatory lug.

In the modified form shown in Fig. 4 of `the drawings, the by-pass 21 in the branch i9 of the housing'S, has been omitted and the operating stem vIl() is made tubular for the conveyance of thev gases'iiito the interior of the housing 41 from the head 42 with whose interior it communicates by means of i an aperture 43 in its wall.

. The device when appliedfto a stove, is preferably' placed below the top-plate 4 and as'much as possible,l in equidistant relation to the various burners '3 as has been shown i in Fig. l. i

As the operation of the appliance hasbeen referred to in the beginning of this specification, no further description thereof is considered necessary at this point and we wish it understood, that while we have shown and -flvscribed the device in the best form now `-:nown to us, variations in the arrangement :i ud construction of the parts may be resorted to. without departing freni the spirit of our i: ,iiventiom f What we claim and desirev to secure by Letters Pateiii is l 2. A device of the class described com-- prising a housing, a plug rotatably mounted therein and having a bore in communica- 'c `tion with the interior thereof, a torch pro-V jectiiig laterally from the said plug in couiiiiunication with its borea headprovided surface of the said housin n bore in communicationy with the interior f `io0` trolled passage', a conduit connectingthe said passage wi'th the interior of the said housing, an o erating ywith a pipe-unionland 'ha-ving"a'valvecon?v Y n stem rotatably mounted in said iead und thesaidhousing,

and coperative transmission means on the said stein and on the said-plug.

3..A deviceofthe class described comprising a housing, a plug .rotatably mounted therein andv having a bore in communicationrfwith the interior thereof, u torch prof jecting laterally from the said plug in communication with its bore, avalve controlled conduit connected with the said housing in communicationwith its interior, a means y for moving the said plug about its axis, and4 a spring adapted to automatically take up the wear on the said plug b A maintaining it resiliently in contact with t evpart of the housing in which it is mounted.

y4r. A device of the class described com? 'i pi'ising a housing, ar plug rotatably mounted 'Y l therein and havingv a bore Vin communication with the yinterior thereof, a torch 4projecting laterally from the said plug in communicay tion with its bore, a valve controlled conduitk connected with the ysaidl housing inl communication with its interior, a rotatory operating stem projecting throughr the said ,l gears on the said` n conduit, `and cooerative stein and on the said ping.

5. A device of the dass ascribed com-VF f prising a housing having a central inwardly directed bearing, a plug rotatably mounted in said bearing, projecting beyond the upper thereof, a torch projecting laterally from vthe upper portionof the said plug in comand having a munication with its bore, a valve controlled n conduit connected with the said housing inv communication with its interior, and means for movin the said plug about its axis of qui.L i

rotation, t e upper surface of the said housing being dished todirect matter disposed thereon toward the said bearing;` c Y 6. A device'of the class described com prisin a valve controlled conduit, ya torch rotata ly mounted in continuous communication therewith, an operating stem projectin'g through said. conduit, and `means for converting ka movement of saidY stem into' a. movemento the torch about its axis of rotation. i Y
