OlL--BURNEFL` SPECIFICATION forming part of Letters 'Patent No. 545,236, dated August 27, 1895.

Application tiled August 18, 1894. Serial No. 520,663. (No model.)

To u/ZZ whom t may concern:

Be it known that I, ROBERT H. LAIRD, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain newr and useful Improvement in Oil-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, wherein- Figure l is a side elevation of an oil-reservoir and my improved burner, showing the application of the burner to a cooking-stove. Fig. 2 is a longitudinal sectional View on line 2 2, Fig. 3. Fig. 3 is a top plan View; and Fig. ft is a cross-sectional view on the line 4 4,

Fig. 3.

This invention relates to a new and useful improvement in an oil-burner, the object being to construct a device of the kind described whereby the oil to be burned is first vaporized and nally thoroughly consumed.

The special features of this invention consist in the combination with a coil for the vaporization of the oil, which coil may be said to terminate in a downwardlyprojecting nipple, which nipple directs the vapor against a deflecting-plate, whence it is spread, and taking up the induced oxygen or air at the edges of the plate is thoroughly consumed. The

3o advantage of such construction is that the oil, after being vaporized and directed against the deflectorvplate, spreads out and induces an inflow of oxygen from the edges of the dehector-plate, at which point the two are intimately mixed, when thorough combustion takes place at the point of mixture. The stream of oil emitted from the nipple is thus within walls of flame, and the heat being so intense at its point of contact with the dehector-plate no particles o'f carbon are freed. Therefore thorough combustion is the result.

In the drawings, A. indicates a reservoir for the oil, and B a force-pump preferably attached thereto, the function of which latter is to subject the oil in the reservoir to a pressure, such parts being of any well-known or desired construction. From said reservoir leads a supply-pipe O, which is provided with suitable cocks and drip-cocks, said supplypipe leading to a coil D, which, as shown in Fig. l,

is located within the cooking-stove, just beneath the plates thereof. This coil D has leading from its end a nipple E, which, as shown in the drawings,projects downwardly g but it is obvious that it may project laterally, 5 5 if desired, depending upon the location of the deilectorplate hereinafter referred to.

Arranged Within the stove or other suitable support is a detlector-plate F, which is preferablyconcaved in its face or in the shape of 6o a saucer, said deflector-plate being in line with the nipple E and beneath the same, whereby when the device is in operation any fluid particles of gas not vapor-ized by the coils D, as might be the case when Erst starting the tire, would be precipitated upon the detlector-plate and held in the cavity thereof until consumed by the llame or until such time as the deliector-plate would be heated to such au extent as to convert the same into 7o gas, when it would be forced out by the ejected gas from nipple E and thrown int-o the path of the induced oxygen, where it would be consu med.

The deilector-plate F is preferably mounted in a suitable frame G, open at its bottom or side, so as to permit the air to flow thereinto to be drawn up around the detlector by the draft created by the fla-mes above the deflector. These draft-induction openings around the 8o dellector are preferably made by forming grooves or serrat-ions in the edge of said deilector or in anyother suitable manner which would permit the air to pass around the same, in order to enable the oxygen to commingle with the carbon'at the edges of the dellector. The frame G, in which the deliector is mounted, is preferably provided with a damperplate H, for the purpose of regulating the admission of air to the tlame.

The nipple E is preferably arranged in a cross-pi pe forming the end of the coil B, said nipple projecting inwardly beyond the bottom of the pipe, so that any sediment or other foreign matter in the coil would not choke the 95 opening of the nipple, thereby permitting the gases freedom to pass therethrough unobstructed.

Having thus described my invention, what I claim, and desire to secure by Letters Patroo ent, is@

l. In an oil burner, the combination with tion extending across the space within thel coil, a depending nipple on the cross-over portion between the/coils, a hollow frame supported in the casing below the nipple, a drip deflector plate secured in the upper end of the frame and having marginal recesses con stituting air passages, and a damper in the holder below the plate, substantially as described.

3. In an oil burner, the combination with a casing,of a vaporizing coil therein having acentral depending nipple thereon, a vertical hollow frame of a diameter less than that ot the coil, a deliector fixed in the upper end of the frame, and having air passages at its edge leading from the interior of the frame, substantially as described.

4. In an oil burner, the combination with a vaporizing `coil provided with a suitable ejection opening, of-a hollow casing arranged in line with said opening, and a drip deflector plate secured in the end of said casing nearest the opening, and having marginal recesses constituting air passages between its edges and the side walls of the casing, substantially as described.

In testimony whereof I hereunto aftix my signature,in presence of two witnesses, this 9th day of August, 1894.

ROBERT H. LAIRD.
