'signed for use in the ordinary forms of cooking ranges and stoves, and it more specifically comprehends an improved construction of the general form of burner disclosed in the Patent No. 826,967 granted to Henry Schneider, July 24, 1906.

Our invention, in its generic nature, comprehends an improved arrangement, of

yburner body having a plurality of gas distributing chambers, a pilot light, and an improved valve mechanism, adapted for controllin vthe feeding inflow of the gaseous fuel, t e quantity of gas to the 1 ilotvlight, and a valve device for directing t e gas into one or more or all of the several distributing chambers. l v

Primarily, our invention has for its object to provide a burner of the general character stated, that shall he simple in construction, capable of being easily made and in which the valve controlling rdevices are all operable from outside the stove, and the effectiveness of the burner readily adjusted.

In its subordinate feature, our invention embodies certain peculiar arrangement and novel combination of parts, all of which will be hereinafter fully described, specifically pointed out in the appended claims and illust-rated in the accompanying drawings, in which Figure l, is a perspective view of our burner, and shows how the same is applied for use. Fig. 2, is a side elevation of the same, part of the valve head portion being in section. Fig. 3, is a top plan view thereof. Fig. 4, is a vertical, longitudinal section of the valve head end of the burner,

the main controlling valve being adjusted to direct the gas to one chamber. Fig. 5, is a similar view, the valve devices being adjusted to direct thc gaseous iuid to two chambers. Fig. 6 is a similar view that 'of the burner, as best shown in shows the valve devices as directing the gas to three chambers. Fig. 7, is an? enlarged detall section that shows the end of the needle valve and the valve for emt'rollingV the flow of gas to the pilot directing ebannel. Fig. 8, is a detail view hereinafter referred to. lFig. 9, is a detail section of one of the air inlet portions of the burner, and

the adjustable gate or slide therefor;

ln thepractical arrangement, our inven? 'tion consists of a vertically elongated b0dy,'

adapted to be tted edgewise in the fire box of the stove or range in the manner illustrated in Fig. i, by reference to which it will be readily seen that the front end, her'einafter termed the valve or head portion, projects beyond the front wall of the fire 4box of the stove suciently to permit of readily manipulating the several adjusting valves hereinafterreferred to.

The burner body consists of the main pot i that is cored. out or otherwise formed into three vertically arranged com artments or chambers a, Z) and c, each of W ich is apertured as at at the front end to readily slip over- 'the short stud like tubes 20-30 and 40 that thread into the valve or 'head ortion 2 i'gs. 4, 5 and 6.

Head portion 2 of the body is a casing vformed with lateral flanges 21 for bolting onto the outer end of the art 1 and the said port-ion 2 is of a greater eight than part 1 where it joins with the passage 4 1s reduced in cross-sectional area, as clearly indicated at 50 in Figs. 4, 5 and 6 of the drawings.

The pilot or self lighter pipe 3 extends inwardly and pro ects into a small chamber 31 ,that has a baille wall 31a against which pipe 3 discharges and which directs the gas flow through a transversely elongated burner openin 82, which I term the pilot burner, ysince rom this burner or light, the other burner orifices in the several chambers a, and c are self-lighted. The flow of gas through the feed passage 5 to passage 4 is.

' that is horizontally disposed and -has its we claim and desire to secure by Letters latent. 1s

handle receiving end projected to one side of the head portion 2 of the burner, see Fig. 1. The gas suppl to the several passages Q5, 35 and L15 that feed the several chambers a,

b and c iscontrolled by the common type of* needle valve 16, th^ threaded part of which is mounted ina gland boss 15 that has a gland cap sleeve 14 threaded thereon in the front end ofthe burner body, The square end. 16a is arranged for receiving a lrey 17, see Fig. 1, for turning it, as described.

Y alve 13 is a two-way valve and is so arranged that when set as in Fig. 4 the main flow of gas will be to chamber a, when set to position shown in Fig. 5 the flow. of gas will be to chambers a and and when turned as in Fig. 6 the will -l'low to all three chamf bers. To cut oft' all of the chambers a, b and c," and to only let thc pilot light burn, the

needle valve 16 is screwed home as in Fig. 7, it being understood, to cut out the pilot light, the valve 'T is screwed down to close the passage. The walls of the several chambers are perforated to provide ample burner orijices and the several orifices or burners will readily light from each other and from-the pilot light. Each chamber a, Z) and c has an air inlet 6G in one side and each of the said inlets has a slide valve or gate (5l-(31, see Fig. S) for regulating the size of the said air inlet.

From the foregoing, taken in connection with the drawing, the complete construction,

the .general advantages and method' of operation of our invention will ybe readily apparent.

By reason of arranging the several chambers as stated sind shown, and combining with them the peculiarly constructed valve head, the heating capacilyY of the burner can be easily regulated, and the burner at all times maintained lighted by regulating the outow to the pilot pipe, as desired.

`Having thus described our invention, what f l. -In a gas burner, ay body having a firing chamberv4 and a supplemental pilot light chambeigsaid chambers each. having discharge orilices in close proximity to one another inl virtue of which the ignited gas issuing from the pilot light chamber will ignite the gas issuing from the tiring chamher, said body portion including a head portion having a single fuel infeed passage that communicates with the pilot light chamber and the firing chamber, and a needle valve that controls the passage of fuel to the tiring chamber.
