UNITED sTA'rEs PATENT OFFICE.
TAYLOR W. HEINTZELMAN, OF SACRAMENTO, AND JAMES G. CAMP, OF OAKLAND, CALIFORNIA.
OIL-BURNING FURNACE.
Application filed June 11, 1912.
To all whom it may concern:
Be it known that we, TAYLOR \V. Hizix'rznnuax, of Sacramento, in the county of Sacramento and State of California, and Janus G. CAMP. of Oakland, in the county of Alameda and State of California, have jointly invented a certain new and useful Improvement in Oil-Burning Furnaces, of which improvement the following is a specification.
Our present invention relates to oil burning steam boilers of the general class or type, exemplified in Letters Patent of the 830.833 and 857,170, @anted and issued to us under dates of September 11, 1906. and June 18, 1907, respectively, in which a rearwardly discharging oil burner is located adjacent 'to the front end of a firebox which is unobstructed by I arches orprojections, whereby the passage of heat from the burner is permitted throughout the, length of the firebox.
The object of our invention is to further improve the structures set forth in the above recited Letters Patent. to the end of attaining mor complete combustion and economical utih/ation of the hydro-carbon fuel. increased duration of service of firebrick linings, and substantial elimination of'carbon in fireboxes.
The improvement claimed is hereinafter fully set forth.
In the accompanying drawings: Figure 1 is a vertical longitudinal central section through the firebox and adjoining portion of the waist of a steam boiler. illustrating an application of our invention; Fig. 2. a vertical transverse section on the line a a of Fig. 1; and Fig. 3. a similar section. the left hand half being taken on the line Z; I) of Fig. 1, and the right hand half on the line 0 0 thereof.
Our invention is herein exemplified as embodied in a locomotive boiler of the present standard wide firebox type, but, as will appear upon a consideration of its essential structural and operative features, it is not limited in application, to this or any other special type or form of steam boiler, being adapted for use inany of the various constructions which are provided with a firebox or furnace and tubes or fines leading therefrom. In the instance herein shown, the inside firebox, 1, is of the usual form and is closed at its top by a crown sheet. 2, and surrounded by upwardly inclined water Specification of Letters Patent.

Serial No. 703,090.
spaces, 3. the bottoms of which are closed by a mud ring, 4, as in ordinary locomotive practice. The outside firebox. 5, is connected to the waist. (3. through which the tubes, 7, pass from the tube sheet. 8, to a smoke box of the usual form not shown) at the front end of the boiler.
In the practice of our invention, the inside firebox, 1, is closed at bottom by a sheet or plate metal casing, which corresponds substantially, in general relation to the firebox, with the ordinary ash pans of steam boilers in which solid fuel is used, and will be herein doscriptively referred to as the bottom pan i This appliance, so far as relates to its primary function of forming a bottom closure for the firebox. corresponds with the similarly designated element of Letters Patent No. 830,833 above referred to, but, in other particulars, diders therefrom, both structurally and operatively. such differences constituting the characteristic and novel features of our present invention, as now to be described. l'nder our present invention, in accordance with the advantageous results of such construction which we have developed by experiment and succeeding application in praptical service. we provide a bottom pan, he floor of which depends downwardly in transversely segmental form, and extends, continuously in such curvature, from one side wall lining of the inside firebox to the other. as clearly shown in Figs. 2 and 3. The floor of the bottom pan comprises a supporting sheet or plate of metal, 9. which fits against and is secured to the bottom of the mud ring. t. at the sides of the firebox, and a fire brick facing: or lining. 11. laid on the supporting sheet. the bricks of said lining being set on ed ge and extending between fire brick linings. l1. 11. which \re fitted against the side walls of the inside firebox, throughout the length of the bottom pan. The oil burner, 12, passes throu h an opening in the front wall. 9, of the bottom pan, the flame from its delivery nozzle havingan uninterrupted rearward discharge therefrom to the rear of the bottom pan, as in the construction of Letters Patent No. 830.833.
The provision of a bottom pan having a floor of continuously curved transversely segmental form, as above described, has been found. in practice. to be of substantial advantage, in the particular of inducing a swirling or curved motion of the current of the flame discharged at the burner nozzle,
.amtinuousl curved se mental floor also enables the volume of combustion space to be increased below the plane of the burner, wit nit involving UbJQCiilOIlitbl8 downward pro} ction of the bottom pan adjoining the i mud ring. or between the side members thereof, and the direct connection of the supporting plate to the mud ring facilitates i insertiiy and detachment when required. "1i e have further found in practice, that the period of service of the lining bricks, when wt on. edge in the curved faced lining of the segmental floor of the bottom pan, is materially increased, and that the accumulation of carbon in the firebox is practically elimihated.
in the instance illustrated, the bottom of the firebox and the mud ring are downwardly inclined from the rear to the front of the firebox, while the floor ofthe bottom pan is horizontal in all longitudinal sections. .so that the pan is deeper, at its rear, which is closed by a metal plate, 9", having a fire brick lining, 11, than at its front, which is closed by a metal plate, 9, having a fire brick lining, 11. The lining of the rear plate, 9', is continued upwardly into the firebox, to or near the bottom of the door opening, fittingagainst the rear wall of the firebox, and fmrniing a lining therefor, by which it protected from the direct action of the heat of the rearwardly discharged current of flame from the burner. The oil is, in ordinary practice, preferably heated by means of a superheater, 17, through which the oil supply pipe, 13, passes on its .way to the burner, and which is supplied with steam from'the boiler, and the oil is atomized and discharged into the firebox bvav jet of steam admitted to the burner, 12, through a. valve controlled pipe, 20. The supply of air to the firebox, for the combustion of the liquid carbon fuel, is, as in Letters Patent No. 830,833, effected below and at the sides ojt the burner, 12, througha plurality of draft openings formed by short tubes, 10,,passing through the front wall, 9*, of the bottom pan, and air is also, as in said Letters Patent, admitted to the firebox through an upper air supply passage, 24, in its rear wall, above the level of the burner, the ordinary door hole being used for this purpose and being controlled by a suitable door provided with a deflecting plate, 27, which may be adju ted to the angle desired for downwardly deflecting the incoming current of air.
Under certain. conditions or in (QUINC- tion with fireboxes of certain idths, it
may be found desirable to make the length of the bottom pan less than that of the firebox, in which case the front wall, 9 of the bottom pan is located at a desired and determined distance in rear of the front of the firebox, and the space between the wall, 9*, and the'front water wall of the firebox is bridged over by a supplemental firebrick floor, 11, as shown in Fig. 1. It will be oh vious, however, that the bottom pan may be made of greater or less length as desired, without departure from our invention.
Our invention has been applied and is now in service in connection with the boilers of a number of locomotive engines, the construction used being, in all essential partied lars, substantially the same as that herein described and shown, and has, n regular service, complied with all the requirements thereof, and attained the improved operative advantages hereinbefore stated.
lVe claim as our invention, and desire to secure by Letters Patent:
1. The combination with a steam boiler firebox of increasing cross sectional area from its top to the bottom, of a bottom pan having av downwardly depending transversely segmental floor extending in a continuous curve across the entire bottom of the fire-box and fitting against and secured to the under side of the mud ring, means for I discharging a hydrocarbon flame from the forward end of and into and parallel to the bottom of the pan, and means for admitting air into said bnttom pan.
. 2. The combination with a steam boiler firebox, of a bottom pan connected to the lower end thereof and having a downwardly depending transversely segmental floor extending in a continuous curve across the.
fire-box and of increasing transverse crosssectional area from its forward to its rearward end, means for discharging a hydrocarbon flame from theforward end of and into said bottom pan, and means for admitting air into said bottom pan.
3. The combination, with a steam boiler firebox, of a bottom pan having a floor comprising a downwardly curved transversely segmental supporting plate, fitting against and secured to the firebox mud ring, and a facing of fire bricks set on edge thereon, a firebrick lining on the rear wall of the firebox, a hydrocarbon burner opening into the forward portion of the bottom pan, and means for admitting air adjacent to the burner;
