HYDROCARBON-OIL BURNER.

SPECIFICATION forming part Of Letters Patent N0. 475,277, dated May 17, 1892.

` Application filed April 6, 1891. Serial No. 387,770. (No model.)

To all whom t may concern.-

Be it known that I, FRANK HAGELIN, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon Oil Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in hydrocarbon-oil burner for steam-generator; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation, and Fig. 2 is a plan, each showing the settingin section. Fig. 3 is a side elevation in section of the burner mechanism detached. Fig. 4 is a front elevation taken outside the setting.

A represents a large-sized air-blast pipe extending along in front of the boiler or extending in front of a series of boilers, according as the case may be, pipe A having a branch pipe a, extending diagonally downward, as shown in Fig. et, and entering the setting under the boiler. Pipe ct extends along near to the one side of the fire-box to the rearward end of the latter and connects with a lateral section a', that in turn connects with section a2, the latter extending forward along near the other side of the lire-box and at the forward end member a2 connecting with the upwardly-inclined section as, that in turn connects with the discharging member co4, the latter presenting rearward and being located under the lateral center of the boiler. The horizontal sections of the air-pipe within the fire-box are located on about the same plane where the grates are usually located in ordinary boilersettings-say about three feet more or less below the bottom line of the boiler.

B is the feed-pipe for the oil, this pipe entering the front end of sections CL2 of the airpipe, the oil-pipe extending to the rear end of section a2 `and returning, from whence it extends diagonally npward opposite the discharge of the air-pipe and from thence rearward, the rearward section thereof b extending centrally inside of member d4 and discharging just inside the latter. (See Fig. 3.) The discharge of the oil is therefore surrounded by the air-blast, by means of which the oil is instantly atomized and commingled with the air and the united product is united just rearward of the discharge.

C is a detlector constructed, preferably, of fire-brick and resting on the bridge-WallE, the detlector having a rounded forward end located in line of the blast, and the llame impinging this detlector is diffused or scattered, so as to fill the fire-box.

The horizontal section of the air-pipe Within the fire-box is covered usually with a single layer of fire-brick laid tlatwise, and after the fire has been burning a short time this lire-brick covering and the ai r-pi pes below become intensely heated, whereby the air-blast is heated to a high degree and the oil Within the feed-pipe coil becomes heated to substantially the same degree as the air, and in such equally-heated condition the air and oil are commingled and united. The conditions, therefore, are most favorable for perfect conibustion, and this is had to such a degree that after the fire is well under way no smoke is visible from the chimney.

D is a coldair duct extending along where the ash-pit is usually located,`the air-duct having an opening cl about under the rearward or discharging end of the burner.

Duct D connects with a large opening c, constructed in the low bridge-wall E, so thatthere is an air passage-way up on either side of the detlector C, and as the llame is spread laterally by the deflector the upward current of air through openin g ecarries the flame up against the boiler. There isadamper (not shown) for controlling the cold-air draft, and of course this damperis opened wide in starting the lire. The air-blast is usually supplied by a fanblower, although any means for producing an Vair-blast will answer the purpose.

The device is simple, inexpensive, and easily regulated, the oil-supply pipe being provided with a valve B for controlling the iiow of oil.

In starting a fire the air-blast and oil are of course introduced without heating, and under such conditions more or less smoke is formed by the condensation of unconsu med gases; but in a short time the apparatus becomes heated,

and when well under Way, as aforesaid, no smoke is formed.

What I`c1aim is- 1. The combination, with a furnace, of an lnjector having a hot-air blast-pipe and an oily supply pipe, a deector, and an air-passage each side of the same leading from the outside to the inside of said furnace and arranged to discharge therein an upward current of air each side of said delector, substantially as described.

2. The combination of a furnace, an injector formed With a hot-air blast-pipe and an oil-
