SPECIFICATION forming part: of Letters Patent No. 394,004, dated Deceznoer 4, 1888. Application filed February 13, 1888. Serial No. 263,815. (No model.)

To all whom if 71mg/ conce/fn.:

Be it known that I, MICHAEL J. ORIELLY, ot' Buit'alo, in the count \Y ot Erie and State ot ew York, have invented new and useful lmw provcmcnts in (;1.s-Sto\'es,ot' which the :tollowing' is a specitication.

'lhis invention relates more pa rticularl v to improvemtmts in that class ot' eras-stoves which are provided with a lighter or small burner connected with the main supplyY -pipe and whereby the main burner is lighted.

'lhe object ot' my invention is to provide a simple and compact device ol' this character, and also to in'iprove the construction ol' the burner and provide the device with an improved air-injector.

The invention consists of the improvements which will be hereinafter t'ulllvdescribethand pointed out in the claims.

ln the accompanyingl drawings, Vlligau'e l is an elevation ot' my'improved lighting' device applied to a gas-stove. Fic'. 2 is a longitudinal sectional elevation ot' the device on an en larged scale. Fie'. Si is a sectional view ot' one of the lmrners, showing' its parts detached. Fig'. 4 is a top plan view ot` one ot' the burners. Fig. is a longitudinal sectional elevation ot' a modified construction ot' my improveinent. Fig. t5 is a cross-section in line c .1', Fig. 5. Figs. 7, S, and 9 are sectional elevations showingl different positions ot' the pl ug' ot' the cock arranged in the main supply-pipe.

Like letters of reference reter to like parts in the several figures.

A represents the tire-place or flame-chamber ot' an ordinary gas-stove, and is a supplypipe, which enters the tlame chamber through an opening in the side of the stove and with which the burners (l C are connected. Each of the latter consists ot'a tube, c, which is provided with perforations c and a series of circular detlecting-plates, c2 c3 c4, surroui'iding` said tube. T h e tube c formed on the upper side ot' the lower detltctingplate, c4, and is screw-threaded externally throughout its entire length. The intermedi ate deiiectingplate, c3, is provided with a central threaded opening, which tits over the threaded tubeJ and the upper defiecting-plate, c2, is formed on a screw-cap, d, which closes the upper end ot" the tube. The plates c2 and c3 are provided on their under side with teats l l l l l i l t c5, whereby the plates are held at the proper distance apart. The `gras-exit openings c are arranged between the detlcctilig-plates c2 ci" c1, and the latter are madeot' `sgradually-dccreasing' diameter toward the upper end ot the tube, so that two circular sheets ot' llame will be produced-one int-losing' the other. H v this construction a large and powerful liame is provided l'or, which will extend over a com siderable area ol 'the tlame-chamlier. The plates c2 cil c* are prett-rablv made concave or curved upwardly, so as to deliect the thune ulnvardlv toward the top ot' the stove. The plates c1 c c* may, however, be made straight or fiat, and instead ot' the teats radial ribs maybe formed on the undersit'leoi thcplates c2 c3 to divide the flame.

The burners C (f are each connected with the supply-pipe B by a short tube, d', which is seated with its upper end in a screwthreaded socket, (l2, ti'ormed on the underside ot' the lower plate, ci.

The lmrner-supply pipe B is divided into two chambers or compartments` F F', by a partition, j", and the burners t' C are respectivel)v connected with these chambers.

j" is an openingl formed in the partition f, wher-eb)v the chambers F F arc placed in communication with each other, and the gras is admitted to both burners (y C.

c/ is a conical valve, which is adapted to close the openingf", so as to exclude the gas from the inner burner, t", if it desired to e use but a single burner. The end of the opening j" adjacent to the conical valve is made conical, so as to form a seat For the valve.

7L represents the stem ot' the valve, which is screw-threaded at its outer end and works in a threaded hub or sleeve, 71', t'ormed on a screw-cap, h2, which closes the outer end of the pipe B. The opposite cud ot this pipe is closed by a screw-cap, h3.

hf* is a hand-wheel secured to the outer end ot' the valve-stem, and whereby the same is turned so as to seat the valve against the openingf and exclude the gas from the chamber F, or remove it from said opening' and admit the gas to said chamber.

l represents the air-injector, which is connected with the burner supply-pipe l5 outside of the stove, and J is the main gas-supply IOO ' or collar,- ot, which engages over a threaded Y.at one end with the gas-supply pipe J.

' )l t ot Oas desired and the )lug m is then l r: v o

Vthe valve and increasing the gas-supplyatter pipe connected with the injector, and which is provided with a valve or cock,j, for controlling the flow ot' to the burners.

y1I represents the spherical casing of the injector, provided at its lower end with a threaded collar,'i, which is screwed upon .a nipple, 2, ot the burner supply-pipe B, and in its side with a screw-threaded socket, '175, into which is titted the end of the gas-supply pipe J.

l.: is a horizontal tube or passage arranged centrally in the Casin g z', and coimnunicating The tube K Ais provided with a dowi'm'ardly-projecting nozzle, 7J, which delivers the gf s into the nipple 'i2 of the burner supply-pipe B.

Z represents a valve arranged in the opposite end of the horizontal tube k, and projecting into the latter above the nozzle 715/, so that by moving the valve inwardly the pipe will be 'partly obstructed and the supply of to the burner-pipe B diminished. The valve] consists ot' an external ly-screw-threaded stem, which works in a threaded opening formed in the end of the tube 7.-.. stem is provided with a notch, so that it can be turned by a suitable tool or wrench. The casing is provided in its side with a threaded socket, m, which is closed by a screw-plug, m.

`When the device is first applied to the stove, the valve l is adj usted to the maximum supsecured in the socket m. prevents the This construction attendant from tampering with the'valve has been properlyT adjusted.

'n represents an opening formed in the upper end of the casing i', and through which air is admitted to the injector and commingled with the gas issuing from the nozzle k before it passes to the burners.

N represents Aan adjustable valve or disk arranged above the opening n, and whereby the admission ot air to' the injector is regulated. The valve N is provided on its under side with an internally-screw-threaded sleeve shank or stem, n?, projecting upwardly from the tube 7L'.

n3 is a screw-plug, which is arranged in a threaded opening in the valve N and the upper portion of the sleeve n', and which bears upon' the upper end of the screw-stem n2 and firmly holds the valve against movement on the stem. Upon loosening the screw-plug n3 the disk N can be adjusted to increase or reduce the supply of air to the injector.

O represents the lighter or small burner, which is arranged within the flame-chamber and in such close proximity to the burner C that the gas issuing from this burner will be ignited by contact with th e flame of the lighter. The gas issuing from the other burner, C', when the latter is used, is lighted by contact with the flame of the burner C.

p represents a supply pipe or passage with which the lighter O is connected, and which nfrom each other,

The outer end of the Y terminates with its inner end in the flamechamber A and with its outer en'd outside of the stove. The outer end ot' the supply-pipe p is connected with the main supply-pipe .T beyond the cock j by a branch pipe, 1J', which is pro vided with a regulating valve or cock, p2. The supply-pipe V2) is arranged within the burner supply-pipe ll, and is cast in one piece therewith, as clearly shown in Fig. 2. This constructioii ot the lighter supply-pipe p and burner supply-pipe B dispenses with an extra opening in the side ot the stove7 which is necessary when these pipes are made separate thereby ren dering the device more compact.

The cocks and p2 are provided with handles q q', whereby they are turned. These handles are so arranged that they will stand at right angles to each other when both cocks are closed7 as indicated in the drawings in the full-line tigures of the same. The dotted-line .gures in the drawings show the position olf the handles when the cocks are partially open, and when the cocks are entirely open the'handle q will lic parallel with the main supplypipe Jv and the handle q will lie at right angles to the branch pipe p. The handle g of the cock p2 is provided with a loop, q2, in which the lower end of the handle q of the cock engages when the latter is in a closed position. l-ly this construction the attendant is compelled to open the lighter-cock p2 before opening the cock ot the main supply-pipe.

o' is a slotted segment formed on or secured to the handle q, and Ar is a similar segment Yformed on the handle q and intersecting the segment r.

'rg represents a pin or bolt passing through the slots of the segments i' 1", and provided with a thumb-nut, ri", whereby the segments are clamped against each other and the handles are securely held in the desired position. Upon loosening the thumb-nutri, the handles can be moved so as to regulate the valves.

\Vhen it is desired to light the stove, the cock p2 is opened by turning its handle into the position shown by dotted lines in Fig. l, whereby the gas is permitted to pass to the lighter O through the branch pipe p and supply-pipe p. The lighter is then lighted from the interior ot the stove. The gas-exit opening of the lighter is so small that but a small quantity of gas escapes therefrom, which is insutiicient to cause explosions when lighting the lighter. lVhen the latter has been lighted, the cock j of the main supply-pipe .l is opened by turning its handle into the position indicated by dotted lines in Fig. l, thereby admitting the to the burner supply-pipe B and burners C C through the injector I, in which latter the gas mixes with air induced through the opening n. As soon as `the gas issues from the burner C, it vis ignited by the flame of the lighter, and the burner C is lighted in turn by the ila-me ot the burner C.

YVhen the gas is turned ottl from the main burners, a putt or concussion of the air takes IOO IIO

plaee at the mouth otf the burners, whieh has a teudenev to extinguish the lighter t). To prevent this the lighter is provided with a small hole, o, arranged near the lower end thtneot', as shown in Fig.

ln the moditied eonstruetion representml in Fig. 5 a tubular burner, S, is employed, whieh is provided with gas-,jets s. The burner is divided into two eoniljiartments or chambers, b" S2, so that the gas ean be admitted to either or lboth ehambers at desire, so as to have the fiame under one or both utensil holes ot' the stove.

The ehamber S2 is t'ormed by the main portion ot' thelulrmlrstube S, and the chamber S is t'ormed b v a pipe, s', arranged within the tube H, the eonsttruetionV ot the inner partition, s', being in all respeets similar to that ot' the lighter supply-pipe p, except. that in the modified mnstruetion the inner pipe is elosed at both ends.

The ehamber S is etnineeted with the main supply-pipe bv a brani-h pipe, T, and the ehamberS2 iseonneeted therewith bvabraneh pipe, T.

LY represents a three-wa)v eoek loeated at the iunetion ot the ln'aneh pipes T T with the main supply-pipe, and whereby the admission ot gas to these braueh pipes is controlled. The plugot' this three-way eoek is so arranged that the gas ean be admitted to either braueh pipe sepalatebY or to both pipes simultaneously. lWhen the plug is in the position represented in Fig. 7, the gas passes through the braneh pipe T to the chamber S and is eut ott' from the chamber ll'hen the plug is in the position indicated in Fig. S, the gas is admitted to the braneh pipe T of the Chainber S2, and when in the position shown in Fig. 9 the gas passes through both branch pipes and into both chambers S In the position illustrated in 5 the eoek Closed.

I elailn as my inventionl. The Combination, with the supply-pipes .l and p', provided with eoeksj and p2, of a handle, q', seein-ed to the plug ot' the eoek p2, and provided with a loop, q2, and handle q, seeured to the plug of the eoekj and engaging in the loop if, substantially as seti forth.
