STOVE OR FURNACE FOR BURNING HYDROCARBON AND OTHER OILS.

SPECIFICATION forming part of Letters Patent No. 258,091, dated May 16, 1882.

Application filed J annary 14, 1882. (N model.) I

To all whom it may concern;

Be it known that I, PEARL MARTIN, a citizen of the United States, residing at Medford,

in the county of Middlesex and State of Massachusetts, have invented certain Improve ments in Stoves or Furnaces for Burning.

Orude,Refined, or Unrefined Hydrocarbon and other Oils, of which the following is a full, clear, and exact description, reference being IO had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view of the fire-pot of an oil-stove constructed in accordance with my invention. Fig. 2 is a plan of the same with the deflector removed. Fig. 3 is a longiwith the deflector removed to show the interior construction. Fig. 6 is a transverse section, enlarged, on the line 00 m of Fig. 3.

My invention relates to certain improve- IIIBII'CSOH the oil-stove for which Letters Pat- 2 5 cut of the United States were granted to me January 22,1878, in which the wicks were placed within sheet-metal casingsor holders adapted to fit within grooves in the inclined sides of the fire-pot; and my invention consists 0 in a fire-pot provided with a series of air-apertures in its sides, located between or at the sides of the wick-grooves, these air-apertures being so arranged that those on one side of the fire-pot will be directly opposite to the i wick-grooves upon the other side, by which construction the currents of air entering the fire-pot from opposite sides are allowed to pass each other without interference and a rotary or rolling movement of these air-currents thus 40 produced, which causes a more perfect admixture of the air with the heavier gases near the bottom of the pot, whereby their combustion is promoted and the heat intensified.

My invention also consists in the combination, with the air-inlet apertures in the sides of the fire-pot, of projecting wings or plates, the surfaces of which form extensions of the sides of the air-apertures, whereby the incoming currents of air are caused to pass over an extended area of heated metal, causing the air to be delivered to the interior of the pot in a rarefied or highLv-heated state, as is necessary to secure the best results.

My invention also consists in the combination, with a fire-pot constructed as described, of a deflector so arranged as to intercept and deflect the incoming currents or air down to the bottom of the pot, thereby causing the air to be projected into close proximity with the perforated oil-pipe and become thoroughly and intimately commingled with the gases rising therefrom, thus insuring their perfect ignition and consumption. t

My invention also consists in the combination, with a fire-pot provided with'air-inlet apertures in its sides and a deflector placed 1 thereover, of a perforated oil-supply pipe located sufficiently far above the bottom of the pot to allow of the free passage thereunder of the currents of air projected downward by the deflector, whereby the heavier gases from the oil-tube are prevented from settling down and remaining at the bottom of the pot as they become thoroughly mixed with the constantlymoving currents of air passing under the oilpipe, and a more perfect admixture of air and gases is thus produced, which stillfurther promotes combustion. V

In the said drawings, A represents thefirepot of an oil-stove, which is of rectangular form, the sides I) being inclined from the top down toward the center, as shown. Each of these inclined sides bis provided with a series of grooves or recesses, 0, within each of which is placed a wick, d, composed preferably of cotton, hemp, linen, jute, or other suitablefibrous material covered with a layer of asbestus. These wicks absorb the oil which flows from the perforated oil-tube B, which extends l0ngitudinally along the bottom of the fire-pot, above the bottom of which it is raised, for a purpose to be hereinafter described. The ends of the pipe B are closed, and it is supported in place by a short branch pipe, 0, which communicates therewith and with a pipe, f, leading to the oil-reservoir, (not shown,) and when the wicks are lighted the flame soon heats the tube B, causing the oil to be convert-ed into gas as it escapes from the perforations 9.

Through each of the sides I) of the tire-pot, between or at the sides of the wick-grooves c, are formed a series of air-inlet apertures, 71/,

tary motion of the air is produced which will materially aid its admixture with the heavier hydrocarbon gases near the bottom of the pot, which are thus prevented from remaining dead or stationary at this point, thus promoting combustion, which beneficial effect would not be produced if the air-apertures on one side were directly opposite to or in line with those on the other side.

On each side of each air-aperture h are two wings or projections, t k, the former on the inner side of. the pot and the latter on the outer side, these wings servingto materiallyincrease the area of the sides of the air-apertures, so that the incoming currents of air are caused to pass over an extended area of heated metal, which causes the air to be delivered to the interior of the pot in a highly-heated state, in which condition it is best adapted to be mixed with the gases therein to produce the maximum degree of heat, and all liability of the combustion being checked or retarded by the entrance of cold air is thus entirely avoided.

Within the top of the fire-pot A is fitted a rectangular top or frame, D, which is provided on each of its longer sides with a downwardlyinclined plate or deflector, E, these plates being so arranged as to intercept the currents of air entering by the inlet apertures h, and thus cause the air to be deflected or projected downward to the bottom of the pot into close proximity with the perforated oil-tube B, where it becomes thoroughly and intimately mixed in the proper proportions with the gases rising as they are constantly stirred up and thoroughly mixed with the currents of air passing under the oil-tube, which would not be the case it the latter rested directly upon the bottom of the pot, and consequently the combus- 55 tion is still further promoted and the heat greatly intensified.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In an oil stove or furnace, the combination, with a fire-pot, A, having its sides grooved for the reception of wicks, of a series of airinlet apertures, h, located in its sides between or at the sides of the Wick-grooves, and so arranged that each aperture h on one side of the fire-pot will be directly opposite to or in line with a wick-groove, c, on the other side of the pot, substantially as and for the purpose set forth.

2. In an oil stove or furnace, the combination, with the air-inlet apertures h in the sides of the fire-pot A, of the projecting wings or plates 11 k, adapted to increase the surface area of the sides of the air-apertures, for the purpose of imparting additional heat to the air entering the fire-pot, substantially as described.

3. In an oil stove or furnace, the combination, with a fire-pot having its side or sides grooved for the reception of wicks and a series of air-inlet apertures located in its sides between or at the sides of the wick-grooves, of a a deflector so arranged as to intercept and deflect the incoming currents of air down to the bottom of the fire-pot into close proximity with the perforated oil-pipe, substantially in the manner and for the purpose set forth. 4.. In an oil stove or furnace, the combina- Witness my hand this 9th day of January, 5
