" ens BURNER.

Application filed August 19,1925. Serial No. 51,139.

This invention relatesto a gas burner and more especially it relates to such a burner intended to heat a steam drum for generating steam to be mixed with oil for furnace heating, although as will be seen, it is admirably adapted for steam generation for other purposes.

The primary object of the invention is to make the burner mechanism automatic in its action, that is to say, it embodies a construcv tion in which the gas is cut off, and consequently the flame is extinguished, and the gas re-lighted according to the exigencies and requirements of use.

A further object is to' so construct the mechanism that it will be durable and simple in construction and not likely to get out of order and be reliable and dependable in operation.

A still further object of the invention is to so construct the mechanismthat the consumption of gas will be reduced to a minimum which obviously results from the fact that the gas is entirely out off from the burner when the burner is in its lowermost position,

or the position inwhich its flame is not needed for the generation of steam.

In the drawings- Fig. 1 is a View somewhat diagrammatic or schematic in character showing the burner in raised or operative position below the steam drum, there being shown in dotted lines, the lowermost position or that in which the gas flame isextinguished. v

Fig. 2 is a plan view of the gas cock partially in section.

Fig. 3 is a cross section taken about online aa of Fig. 2.

Fig. 4c is a central section of the nozzle at which is maintained the furnace heating flame. Referring to the drawings, the numeral 1 designates the steam drum that may beof any approved" construction. but preferably of flattened'ovoid shape, as shown. This contains a steam coil 2 having small perforations 3 therein. To the lower portion of the drum is connected a vertical steam pipe 4 which hasits lower end let into the nozzle 5, which nozzle will later be described in detail.

Connected to the lower endof the nozzle is an oil pipe. 7 leading to any suitable source of oil supply, and as will later appear, the action of the steam from thesteam drum issuing through the nozzle, which specially con:

structed, will act as an, injector to draw the oil into the nozzle to. be therein mixed with the steam and air, which mixture is ignited at the nozzle to maintain an intense heat within the furnace, for instance, the mixture constituting a fuel to. take the place of'coal or furnaces. I The more important part of my invention which I now stress has to do with the burner 'mechanismi The numeral 8 designates the gas cock, and by reference to Fig.2 this will be seen to be constituted by a base 9 for attachment to any suitable support and a short upright or standard 10 which terminates in a laterally extending conical key 11 surrounded by a snugly fitting rotatable body or sleeve 12. This sleeve is provided on one side with an apertured internally threaded boss 13, the aperture being Virtually a continuat on of the hole 14 in the sleeve, which hole at times is adapted to register with a port 15 i in the wall of the key, which port communicates with a chamber 16 in said key.

Threaded into the key and opening in said chamber is the' nipple 17 upon which is threaded the T connection 18, to which in turn is connected in the usual way the gas inlet pipe 19 communicating with the house main, or other source of gas supply. Threadedinto the T and communicating with the gas source is a pilot burner 20 whose open outer end extendsinto close proximity to the nozzle 5, as clearly shown in the main figure, so as will presently appear, it will always be in poother combustible material commonly used in sition to re-ignite' the Vapor at'the nozzle when-necessary or desirable in" the opera tion of the mechanism. This pilot burner, as

just, intimated, is maintained constantly throughout the entire time, in which it is desired tobring about automatic operations of the mechanism. 1 I

Threaded into the threadedopening inthe boss 13 is the burner tube 21,Which is bent atits outer end to form a circular burner 22 having in the top thereof aseries of properly spaced and sized holes 23 in position to direct the flame against the bottom of the steam;drum, the circular formation of the burner.- permitting it to surround the steam pipe 4 leading from the drum to the nozzle.

Preferabl I arrange the'holes in the burner at an an e so that when it is in raised post tion under the drum, the flame will be directe'd in true vertical direction because when the burner is in raised position, it is the only time that the gas cock is open and that the flame is extant.

On the side of the sleeve opposite the burner tube is an arm 24- bifurcated as indicated at 25 for the reception of the upper endofa short link 26 which is pivoted in the bifurcation as shown. The lower end of the link is pivoted at 27 in a similar bifurcation in the upper end of a piston rod 28 which 8X- tends through a properly packed stufling box 29 formed in a cap 80 which closes the upper end of a steam cylinder 31, the rod being provided with a piston 32. The lower end of the c linder is closed b a can 33' into the bottom of whichis threaded a short pipe 34.- having a branch 35 connected w1th a steam pipe 36, which 111 connection with the nozzle will be presently described. The

cap 33 at the bottom of the cylinder is provided with a flange 38 to which are attached the lower ends of two spiral springs 39 whose upper ends are attached to a cross bar 40 carried by the piston rod, the springs exerting their force to bring the piston to its lowermost position in the cylii'ider, thereby raising the burner and opening the gas cook.

The water supply in the steam drum may be regulated by a suitable thermostat opcrating through a rod a upon a suitable valve Z). This thermostat operates to supply water to the coil when necessary, and since the burner is operated by steam pressure, as will later appear, through the cylinder and its connections with the burner, there will be no steamwhe'n there is no water, but the drum will be in a highly heated condition due to the fact that the burner will be in raised position and the cock open and in readiness to generate steam immediately the thermoactuates the valve governing the water supply to the coil.

The key of the burner, it will be observed,

is somewhat like the lrey in an ordinary gas fixture except in the present instance, ltlS differently chambered and there is provided as indicated at 4:1 the usual nut for drawing the key into the sleeve to bring about the necessary tight fit between the key and body. Referring particularly to Fig. 4;, it will be noted that the nozzle 5 is of shell formation, and as shown preferably conical. It

has a flame orifice 6 communicating with a chamber 'A. In thls chamber 1S a core B somewhat smaller than the chamber and shaped like the chamber, so that a space 6 will be left between the walls of. the shell and the core. The core is chambered as indicated at D, communicating with this chamher is a pipe E, which with the chamber D virtually forms a continuation of the steam pipe l. Extending upwardly from the chamber D to the space around the core are a series of perforations F, the purposes I of which will be presently described.

mission of air into the nozzle in the operationiof the device. Let into the bottom of the nozzle is an oil supply pipe 7 leading toany suitable-source of oil supply, and it will be noted that the pipe E extends centrally through the pipe 7 andpasses therefrom. The pipe E extends some distance beyond the oil pipe and is fitted with a: T to which is connected as shown, the pipe 36 through which steam passes to-the cylinder through the branch 35 as shown, the branch pipe being located just above the drain cook 36. I preferably extend the pipe/E beyond its connection with the pipe 36 and provide the extension which is designated by H with a gauge 1 and the lower end of the pipe H is preferably provided with a trap JJ In operation water is supplied to the coil 2 and with the parts as shown in the position in full lines in the main figure,=the ports in" the sleeve and key will be'in registry and the gas turned on. Atth'e start the burner and pilot are lighted with a match, the dome heated and water turned on. If the dome is well heated, formation of'st'eam'is almost instana taneous, and the steam passes through the steam pipe 4, into the nozzle 5 in which it is mixed with the oil and air and sprayed into the zone that it is desired to heat. The steam passing into'the core B is divided, part pass ing into the pipe E and part deflected through the perforations Ftoward the top of the nozzle. The portion of the steam whose direction is reversed and caused to pass through said perforations acts as an injector to draw the oil or oil vapor into the nozzle for ignition at the top of the nozzle. At the same time by the same injector force airis drawn into the nozzle" through theperforations G so that there isa mixture in the nozzle of steam, oil, or oil vapor and air, which when ignited maintains, as is obvious, an in Ill) in the cylinder the springs 39 will draw the cylinder to its lowermost position, raising the burner to position to generatesteam in the drum, the burner being re-lighted by the'dying'flame above the nozzle.
