HENRY STACEY, OF INDIANAPOLIS, INDIANA, ASSIGNOR OF ONE-HALF TO MICHAEL I-I. GAIN, OF SAME PLACE.

OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 494,992, dated April 4, 1893.

Application filed July '7, 1892. Serial No. 439,298. (No model.)

To afZZ whom it may con-cern.-

Beit known that I, HENRY STACEY, of Indianapolis, county of Marion, and State ofIndiana, 'have invented certain new and useful Improvements in Oil-Burners; and I do hereby declare that the following isa full, clear, and

exact description thereof, reference being had to the accompanying drawings, in which like gnres refer to like parts.

My invention relates to new and useful improvements in the construction of what are known as oil or hydro-carbon burners, and it relates more particularly to one thatis adapted to burn the crucler grades of oil, and for use in connection with boilers, kilns, puddling and other furnaces where a constant and intense heat is required.

In the drawings, Figure l is a View partly in section and partly in elevation, showing my burnerin place beneath a horizontal boiler of the ordinary type. Fig. 2 is a horizontal section through the burner on the line -Ja Fig. 3, showingthe grate bars upon which it rests, and the surrounding lling of brick. Fig. 3 is a cross section through the burner on the line y-y, Fig. 2.

In detail, l represents a boiler of the horizontal type set in place within suitable walls', within which is formed the lire-box 2, 3 being the bridge wall, and 4 the grate.

5 represents a burner, which, as shown in the drawings, has an oil chamber in its base formed with an angular bottom, and into this oil from the pipe 6 is adapted to flow, the pipe being connected with an oil supply at any suitable point, and having a regulating valve 7 convenient to the boiler.

8 are the inner walls of the burner surrounding it on three sides, the front being open, and a top or deflector 9 being formed above such burner walls, and sloping downward toward the front of the same, thus contracting the open front of the burner to a long narrow slot whereby a space is formed in the upper partof the burner for the accumulation of Vapor therein. The mouth can be adj usted to suit the flame or re that may be desired. The walls S of the burner are perforated as shown, these perforations opening into the air chamber l0 formed between the inner walls 8 and the outer walls ll of the burner, as shown in Fig. 2,the bottoni of this air chamber being open to allow the current of air from beneath the grate upon which the burner rests to circulate freely through such air chamber and through the perforated in-V ner wall 8 directly into the burner, and there mixing with the Vapor arising from the oil after it has become heated. The burner S is preferably set with its back against the bridge 6o wall of the fire box, and around the sides and the front of the saine the grateis covered with brick or other iire-proof material, so that all the air which supplies the burner must come up through the air chamber formed within 6 5 the outer walls of the burner.

An artiiicial air draft is not at all necessary in my burner where it is possible for air to reach the burner otherwise, as in ordinary grates, but where the structure is such that 7o it is impossible for air naturally to reach the burner, an artificial air draft may be obtained by means of pipe 13 which leads through the bridge wall into the back of the burner, as shown in Fig. l, thus supplying an air current from any suitable source. The point of entrance for the air draft and likewise for the oil supply pipe of the burner may be changed, however,according to circumstances.

It will thus be seen that my burner does not 8o require an artificial air draft as found in other hydrocarbon burners, this feature being rendered needless by the construction of my oil chamber whereby a space for the accumulationk of vapor is provided in the upper part of the oil chamber and above the oil.

In most cases my burner would be constructed of metal, but in peddling' or similar furnaces where a Very intense heat is required, it would be preferably formed of lire clay or 9o brick, but the form of the burner and the material used in its construction may be changed to suit the different uses to which it would be put, as in Vertical boilers and similar furnaces my burner would be constructed with the mouth above the burner, instead of in front, this being accomplished by curving or turning up the outer end of the deflector, and also the outer end of the bottoni of the burner.

In kilns and similar fnrnacesI preferably set roo or form the-burner on a solid base, and omit the outer Walls 11, the Walls of the kiln forming the outer side Walls of the burner, and the air draft entering the burner from the rear and through the rear perforated Wall, the inner side Walls being perforated or not as occasion demands.

What I claim as my invention, and desire to secure by Letters Patent, is the following:

1. In an oil burner, an oil chamber having perforated sides, except on one side which forms a narrow mouth, and the top so ar ranged that some of the vaporcan accumulate in such oil chamber above the oil, substantially as shown and described.

2. An oil burnercomprising an oil chamber having an inclined bottom, a closed top inclined toward the bottom, forming on one side a narrow mouth, the Walls of such chamber perforated, and a surrounding air chamber, substantially as described.

.3. An oil burner comprising an oilchamber having some of its Walls perforated, and a surroundinggair chamber, with a closed top -an'd operi bottom, substantially as shown and described.

4. An oil burner provided with an oil 'chamber inlits basehavingan inclined bottom, such chamber adapted to be connected Vwith an oil supply, an inclined deflector or cover above such burner forming ay long narroit1 mouth in the front of the samethiough which the products of combustion pass, perforated walls on the other sides of such burner which open into a surrounding air chamber, Such chamber having a closed top and an open bottom, such burner adapted to rest on a grate within the fire-box of a furnace, and supplied With a draft through such air chamber, substantially kasshown and described.

5. An oil burner comprising an oil chamber having an inclined bottom, a closed top inclined toward the bottom, forming on one side a narrow mouth, the walls of such chamber perforated, anda surrounding air chamber having a closed top and an open bottom, substantially as shown and described.

` 6. An oil burner connected with an oil supply, such burner consisting of an oil chamber surrounded on three aides by inclosing perforated walls, the fourth being narrowand open, and its top so arranged that some of the vapor will accumulate in such chamber above the oil, an air chamberformedabout such oil chamber, the top of such air chamber being closed and the bottom open, `siich burner adapted to rest on a gratepvvithin the firebox of the furnace, whereby the air from below such grate may pass up through the air chamber into the oil chamber, substantially as shown and described. n

Infwitnes's whereof I have hereunto Set my hand this 9th day of June, 1892.

HENRY STAOEY.
