SMITH, BOTH HYDROCARBON-BURN ER.

SPECIFICATION forming part of Letters Patent No. 404,804, dated June 4, 1889. Application filed February 26, 1889. Serial No. 301,235. (No model.)

To all whom it may concern.-

Be it known that I, l/VILLIAM SNEE, a citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in HydrocarbonBurners; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to, hydrocarbonburners adapted to burn crude petroleum for generating steam in boilers of locomotive or stationary engines; and it consists in, the improved consti notion of the fire-box and in the co1nbination,with the fire-box, of valves for feeding air to the combustion-chamber, and thereby regulate in a simple and expeditious manner the amount of heat.

On the accompanying drawings I have shown my invention as applied to the boiler of a locomotive, showing the boiler and firebox of the same.

Figure 1 represents a longitudinal sectional View, 011 a vertical plane, of a locomotive boiler and fire-box, according to my improved construction; and Fig. 2 is a View from the under side of the fire-box, showing the circular valves and the levers for operating the same.

Like letters of reference denote corresponding parts in both the figures.

Reference being had to the drawings, the letter A designates the boiler, which is provided with the usual fiues B, of any approved construction and arrangement.

0 is the fire-box, inside of which I place a combustion-chamber D of the peculiar shape and construction shown in the drawings.

This combustion-chamber consists of a hood E, of a Width corresponding to the width of the fire-box and extending from one side of the same to the other. I prefer to make this hood of iron or other suitable metal, with a hollow space inside, which is filled with fire-clay or other refractory material capable of withstanding intense heat. This hood forms a crown or arch F immediately above the burner G, and is then bent in a down ward and forward direction, as clearly illustrated on the drawings, extending toward the front part of the fire-box.

Below the forward part of this hood and in front of the burner is placed a deflector H, made of the same material as the hood proper and operating in conjunction with the forward part of the same to form a'cont-racted mouth-piece, as shown at I. This deflector II also extends clear across the fire-boxfrom one side to the other, thus forming, in conjunction with the hood, the dome-shapedcombustion-chamber D, provided with the oblong outlet or mouth-piece I.

The burner (shown at G) may be of any approved construction adapted to burn crude petroleum, either by itself or in conjunction with a jet of steam The fuel is fed to it by means of a feed-pipe .I, provided with a suitable valve or valves, and bent at right angles, as shown at J, its upper end being c011- nected to a suitably-located tank or reservoir containing the liquid fuel. If the burner is designed to burn hydrocarbons mixed with steam, the steam-pipe may be conveniently located inside of the feed-pipe J, so as to heat the hydrocarbon as it passes up into the burner. I desire the same to be understood, however, thatI do not limit myself to any particular type or construction of burner, as

my invention consists not in the construction of the burner itself, but in the construction and combination of parts of the combustionchamber and air-valves.

The bottom of the combustion-chamber D is perforated, and covered on its under side by a circular disk K, having apertures 70 registering with the apertures in the bottom of the combustion-chamber. This aperturcd disk K has a central opening through which pipe J is inserted, so that said pipe Will form a spindle or journal for the disk, around which it may be turned. The periphery of the disk is supported by and slides in an an-' nular flange L, fastened to the under side of the fire-box and overlapping the under side of the movable valve-disk K.

The central part of disk K is provided with a downwardly-projecting sleeve or collar M, which turns upon thatpart of pipe J inserted through it, and is provided with a lever N, projecting in front of the fire-box, and having a handle whereby it may readily be manipulated by the fireman or engineer in charge.

Another valve K, of precisely similar construction, is located in the bottom of the firebox immediately in front of the opening or outlet I of the combustion-chamber, and is manipulated by means of the handle or lever N. If desired, additional valves for regulating the supply of air to the fire-box may be located in the front wall of the latter, as indicated at O and P.

In some cases it may be desirable to provide the fire-box back of the combustionchamber D with a transverse breast-wall Q, for the purpose of deflecting the products of combustion over the top of the same before reaching the Ilues. This, however, is not essential.

The operation of this apparatus is as follows: After the oil has been turned on and is ignited in the burner in the usual manner, the valve K is so adjusted as to feed a sufficient quantity of air into the combustionchamber to generate heat enough to vaporize the oil. After a little while the hood E F will be raised to a very high temperature by the combustion of the gases with which it is filled, and by now closing or partially closing the bottom valve K, at the same time opening valve K, the gas which is generated within the combustion-chamber, and therein superheated to a temperature considerably beyond the explosion-point, will ignite on being supplied with air enough, through valve K, to permit of combustion. Thus a flame of in tense heat will issue from the outlet I,which,

by impinging upon and curving around the dome F of the eombustion-chamber,will maintain the heat within said chamber, thereby maintaining a constant supply of gas from the burner. By judiciously regulating the supply of air through the valves K and K, and the auxiliary valves 0 and P when the latter are used, the temperature within the fire-box may readily be regulated at will, and by closing all the valves the fire will be we tinguished in a moment.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a boiler-furnace provided with a firebox, the combination of the fire-box, the domeshaped hood within the same bent downwardly and forwardly at its front side, the deflector arranged below the forward part of the hood, and the burner located below the arched top an d within the hood, substantially as and for the purpose shown and set forth.

2. In a boiler-furnace provided with a firebox, the combination of the exterior fire-box communicating with the fines of the steamgenerator, the combustion-chamber located within the fire-box having an arched or domeshapedtop and narrow mouth or outlet faci n the front end of the fire-box, the burner located within the combustion-chamber below its arched top and back of its outlet, the air valve in the bottom of the combustion-chamber encircling the burner, and the bottom valve in the fire-chamber outside of the comlnistion-chamber, but below the outlet of the same, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto alfixed my signature in presence of two witnesses.

"ILLIAM SNEE.
