OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 460,902, dated October 6, 1891. Application filed April 13, 1889. Serial No. 307.120. (N0 model.)

To all whom it may concern:

Be it known that I, RUnoLE WINKLER, a citizen of the United States, residing at Detroit, county of IVayne, State of Michigan, have invented a certain new and useful Improvement in Oil-Burners; and I declare the following to be a full, clear, and exact description of the invention, such as 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.

My invention relates to a new and useful improvement in an oil-burner; and it consists of the devices and appliances and their combinations, as more fully hereinafter described, and set forth in the claims, and more particularly illustrated in the accompanying drawings, in which Figure 1 is a horizontal section of a portion of a combustion chamber or furnace. Fig. 2 is ahorizontal section of the burner, and Fig. 3 is a vertical section of the burner.

I carry out my invention as follows:

A represents the combustion-chamber of a B denotes the side walls thereof, and B the front of the furnace.

My improved burner consists, essentially, of an inclosing case 0, forming a vaporizingchamber C, said case terminating at its forward end in a nozzle C preferably made flaring, so that the mouth of the nozzle will be elongated. The nozzle is also preferably cut away at the sidesas, for instance, at c 0'- to allow the freer distribution of the vaporized oil and to permit its being discharged broadly into the combustion-chamber.

D represents a steam or blast pipe entering the case C, and preferably extending therein, so as to penetrate the nozzle C the steampipe itself terminating in an expanded or flaring nozzle (Z. This nozzle is also con tracted vertically, as shown in Fig. 3.

E and E are air-pipes communicating with the interior of the case 0, and suitably extended therein, as shown, so as to throw the inflowing air well toward the nozzle of the burner.

I is a supply-pipe to feed the oil to the nozzle of the burner, the said supply-pipe entering the top of the nozzle 0 as shown, and

preferably terminating in said nozzle with a crescent-shaped d ischarge-nozzlef, the mouth of which is suitably contracted to govern the discharge of the oil therefrom in a thin crescent-shaped sheet and directly forward of the nozzle of the steani-jet through the pipe D.

It is to be particularly observed that the openings in the terminal ends of the oil-pipe and steam-pipe, respectively, are of analogous form and that they are elongated in the same direction, the opening in the oil-pipe being in advance of and slightly above the opening in the steam-pipe. The arrangement is therefore such that the oil will feed from the top, being emitted into the vaporizing-chamber in a thin elongated sheet directly in front of the blast issuing from the pipe D, also in a thin elongated blast under pressure, at substantially right angles to the sheet of oil as it is 7c being emitted from the oil-pipe, whereby the oil is instantly sprayed. This construction and arrangement of the terminals of the oilpipe and blast-pipe proves to be of great efliciency. The case 0 acts as a shield to pre- Vent the sprayed oil from striking the bottom of the boiler.

The oil-supply pipe I prefer to lead through a superheater of any desired construction,- (shown in outline at G,) and having a steam- 8o heating pipe II, leading thereinto.

The operation of the device is as follows: The steam-jet through the pipe D, acting as an injector, creates a draft of air through the pipes E E toward the nozzle O of the burner, while at the same time the expanded jet of steam through the nozzle (Z, immediately in the rear of the crescent-shaped nozzle of the oil-pipe, immediately penetrates the oil as it is discharged through the nozzle f, and the coininingled air, oil, and steam is discharged broadcast through the flaring mouth of the nozzle C in the form of vapor into the combust-ion-chamber and readily consumed. The oil-pipe may be provided with a regulatingvalve f. An additional valve f may be provided to regulate the flow of oil through the super-heater.

The device is obviously simple, not liable to get out of order, easily operated, and very I00 efficient. The elongation of the openings in the terminals of the oil and steam pipes is in the same direction and should be made on the arc of a circle, so that the steam emitted radially from the one opening will vaporize and spread the oil in radial lines laterally as well as straightforward, the radial or lateral dissemination of the vaporized oil being a matter of much importance, as thereby much better combustion and every way more satisfactory results are attained.

I prefer to slightly depress theupper edge of the nozzle 0 so as to force the vapor more effectually upon the flame, and more especially to prevent it from striking the boiler and coating it with carbon. By thus constructing the nozzle the vapor in combustion is kept down and away from the boiler, so as to be wholly consumed, leaving the boiler free and clean from any deposit thereupon. So, also, as shown, I prefer to taper the case C toward the forward end or nozzle C in order to more effectually concentrate the air and commingle it more efficiently with the steam and vaporized oil.

WVhat Lclaini as my invention is- 1. In an oil-burner,the combination of an oilpipe F, having a vertically-extended extremity terminating in a narrow elongated opening curved in the arc of a circle in its lower end for the emission of oil therefrom in a vertical thin elongated sheet, and a blast-pipe D, extending at an angle to the oil-pipe and terminating at its forward end in a narrow elongated opening curved in the arc of a circle for the emission of a jet or blast therethrough in a thin elongated sheet to spray the oil emitted from the oil-pipe, said openings being each elongated in the same direction and the 7 opening of the oil-pipe arranged in advance of the opening in the blast-pipe in proximity thereto, substantially as described.

2. In an oil-burner, the combination, with a case, of an oil-pipe F, led into the top of said case and terminating in a narrow elongated opening curved in the arc of a circle in its lower end for the emission of oil therefrom in the vertical thin elongated sheet, and a blast-pipe D, extending at an angle to the oilpipe and terminating in a narrow elongated opening at its forward end for the emission of a jet or'blast therethrongh in a thin elongated sheet to spray the oil emitted from the oilpipe, said openings being each elongated in the same direction and the opening of the oilpipe arranged in advance of the openings in the blast-pipe in proximity thereto, substantially as described.

3. Inan oil-burner, the combination, with a case forming a vaporizingchamber and provided with a nozzle cut away at its sides and laterally extended and vertically contracted and curved in the arc of a circle, of an oil-pipe led into the top of said nozzle and terminating in a narrow elongated opening curved in the arc of a circle in its lower end for the emission of oil therefrom in a vertical thin elongated sheet, and a blast-pipe D, ex-

tending at an angle to the pipe, terminating in a narrow elongated opening at its forward end for theemission of a jet or blasttherethrough in a thin elongated sheet to spray the oil emitted from the oil-pipe, said openings being each elongated in the same direction and the opening of the oil-pipe arranged in advance of the openings in the blast-pipe in proximity thereto, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.
