UNITED STATES PATENT OFFICE.

JOHN DUBELMAN, OF DETROIT, MICHIGAN, ASSIGNOR OF TWO-THIRDS TO WILLIAM H. ASHWELL AND CHARLES R. ROBERTSON, OF SAME PLACE.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 528,292, dated October 30, 1 894.

Application filed January 30,1894.

To @ZZ wh om it may concern:

Be it known that I, JOHN DUBELMAN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and u seful Improvements in Oil-Burners, of which the following is a specification, reference being had therein tothe accompanying draw. ings.

The invention consists in the peculiar construction of a burner designed for burning petroleum or other similar oils in combination with steam and air feeding devices; further in the peculiar construction of the burner pan, the steam generating chamber, the oil and air supply devices therefor, and further in the peculiar construction, arrangement and combination of the various parts.

In the drawings, Figure l is a perspective View of my improved burner. Fig. 2 is a vertical, central, longitudinal section thereof. Fig. 3 is a plan View of the pan showing the air feeding standards in section. Fig. 4 is a cross section on line :n.Fig. 2. Fig. 5 is an enlarged perspective view showing the steain' and oil feed pipes.

The burner pan comprises the bottom plate A, having the inclined section B, front fiange C, and side walls D which are cutaway about half their length to a height corresponding substantially tothe height of the front flange, and the rear wall E formed of fire brick and having the inclined forward face F. This burner pan I preferably form of a single piece of cast metal.

The steam generator rests upon the top of the pan being supported upon the side and end Walls, as plainly shown inthe drawings, and which consists of two parallel sections G G of pipe, provided with suitable heads Gr2 connected at the rear end by a suitable connecting nipple H, the whole forming substantially a U shaped tube or pipe of considerable diameter, say about two or three inches, having a water inlet pipe I at the bottom of one end andA a steam inlet pipe .I at the top ofthe other en d, these pipes entering through the caps G2.

About the middle of one or both of the caps Serial No. 498,447. (No model.)

I arrange a drip cock Kto enable me in case 5o too much water is fed in the generator to assist in more readily making steam.

The front flange of the burner pan is provided with the curved bearing L in which is supported the fan shaped nozzle M, being secured in position by means of the strap N.

O is a T secured. to the outer end of this nozzle, the side opening therein receiving the end of the steam supply pipe J, while the outer lateral opening receives a plug P, hav- 6o ing a bracket Q secu red thereon, provided at its upper endwith a bearing in which is secured the oil pipe R. This oil supply pipe at its outer end is provided with a downwardly extending fan shaped nozzle S arranged in front of and slightly above the discharge aperture of' the steam nozzle. On both sides of the line of discharge of the steam nozzle is a series of vertical, tubular air. supply standards T preferably formed integral with 7o the bottom plate of the burner and having the slots or openingsT on their forward faces only.

Suitable valves are supplied, not shown, for controlling the supply of oil and water to the device in any requisite quantities.

The parts being thus constructed, their operation is as follows: To start it the oil is allowed todrip into the pan, falling u\pon the inclined portion B of the bottomplate, from 8o which it will fall quickly onto the bottom plate Aand be ignited and flames will generate steam in the steam generator. As soon as steam is generated'the steam discharging from the nozzleM will catch the oil dripping 85 from the oil nozzle S, spraying it and commingling with the steam in the burner pan, directing it against the fire brick back E in the pan which will deect the iiame upward around the generator tubes and into the fur- 9o nace to be heated. Air will be supplied through the sides and through the slots T of the standards T, which will assist in distributing the combustion through'theentire length ofthe pan. By arranging the slots T on the rear face of' the standards there is little liability 'of their filling up in use and at the same time the jet action of the steam be'- side the standards will act to draw a large Volume of air through these standards and into the burner to aid combustion.

It will be noticed that I make the forward end of the nozzle M in the shape of a segment of a circle, so as to throw out a Vertical fan tail spray, and I correspondingly curve the oil nozzle S so that the oil Will be evenly ds tributed in the combined stream at all points through the burner pan.

What I claim as my invention is- 1. In an oil burner, the combination with a steam generator, a pan, an oil supply pipe, a steam supply pipe arranged in a horizontal plane with the pan, tubular standards on the pan having open lower ends and arranged in the path of the steam jet and having openings in their rear sides, substantially as described. 2. In an oil burner, the combination ofthe burner pan, a steam generator supported on the pan, the jets for supplying the uid and vapor thereto, the tubular standards T having the slots T on the side farthest from the jets, and the back plate E of the burner pan of fire brick having the inclined face F, substantially as described.

In testimony whereof I ailix my signature in presence of two witnesses.

JOHN DUBELMAN. Witnesses:

M. B. ODoG-HERTY, O. F. BARTHEL.
