HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 773,488, dated October 25, 1904. Application filed December 30, 1903. Serial No. 187,l9 6. (No model.)

To all whom it may concern:

Be it known that I, CHARLES BREN ELLMIRT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Hydrocarbon- Burners, of which the following is a specification.

My invention relates to improvements in hydrocarbon-burners, the object of my invention being to provide a device of this character which can be used either with refined oils or with distill'ates in cook stoves or ranges, in heating-stoves, open fires or grates, furnaces, or hot-water heaters, which shall be perfectly safe in operation, which will burn the oil or distillate without noise, ashes, odor, or objectionable soot and with a steady even heat, which can be readily lighted, which will not clog up from any cause, which can be used in a cook stove or range without drilling holes into the stove or otherwise Inutilating the same, and which shall be adjustable for dif ferent sizes and varieties of stoves.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 isa side elevation of a cook-stove equipped with my improved burner. Fig. 2 is a vertical longitudinal section of the upper portion of the stove, showing the burner therein. Fig. 3 is a perspective view of the burner detached. Fig. 4 is a perspective view of an air-closure used with an upward draft of air to the burner. Fig. 5 is an enlarged front view, showing the manner of adjusting the burner.

My improved burner comprises twoprincipal castings, a rectangular base-plate 1 and an air-conduit 2. The base-plate is formed with a peripheral vertical flange 3, this flange being somewhat higher at one end, as shown at 4, and the conduit 2 has a downwardly-extending wall 5, formed at its lower edge with slots 6, through which and through the raised flange 1 are passed bolts 7, securing the burner to the base-plate. By means of these slots the height of the burner can be adjusted as desired with reference to the base-plate. The main body of the conduit consists of a horizontal portion 8 for the passage of the air, said portion opening downward at its end, as shown at 9. pipe 10, which is passed through and supported by a perforated lug 11, depending from the conduit and the end of which pipe is preferably bent downward to discharge the oil. The oil dropping from said pipe falls through the aperture 9, through which the air passes, onto a circular vaporizing-plate 12, supported by upstanding lugs 13, cast upon the base-plate. Around 'said aperture 9 the conduit flares, as shown at 14, to a diameter substantially equal to that of the vaporizingplate, thereby causing the flames to spread around the conduit. I

It will be observed that the oil-pipe is supported close to the top of the air-conduit. The advantage of this'construction is that thereby the oil is maintained as cool as possible in said pipe. The principal difficulty in constructing an oil-burner for burning California oil is the tendency of the oil to leave deposits in the pipe, which deposits sooner or later clog up the pipe. This deposition takes place more readily the more the oil is heated in the pipe. It is therefore of great importance to keep the oil cool up to the point that it is discharged. The above construction enables this to be done.

In use with a cook-stove the usual grate is removed and is replaced by a metallic plate 15, which is made air-tight by fireclay or other suitable means, and the burner is laid thereon. conduit through a small hole in the plate 16, passing into the stove through the hole 17, usually found for fitting the grate into the stove. A valve 18 outside the stove controls the supply of oil.

The conduit 2 has a lip or shelf 19 extending forward from its top as far as the door of the stove, (shown at 20.) The spaces between the sides of the conduit and the sides of the In this conduit is located the oil- The oil-pipe leads upward to the lire-box at the entrance thereto are iilled with lire-clay (shown at 21) to substantially cut off the entrance of air into the lire-box except through the conduit. in order to adjust for (,li'lierrnt sizes of stoves, the lip or shelf 19 is formed with two transverse grooves 22, di viding said lip into three substantially equal sections and rendering it easy to break off one or two of the sections, as may be desired, according to the size of the stove.

In use the valve is opened and a small quantity of oil is permitted to drop upon the vaporizing-plate. A piece of paper or other inflammable material is then lighted and passed into the air-conduit and allowed to drop upon said vaporizing-plate, igniting the oil. The oil then burns around the flange 14, heating the same. The vaporizer quickly becomes sufliciently hot to immediately vaporize any oil falling thereupon, and the perfect combustion of the vapor of the oil is assisted by the heat of the ant-supply thereto, which is highly heated by the flames ascending around the air-conduit. .l find thatit is ofthe greatest importance to highly heat the air-supply for burning the oil, and my presentconstruction enables this to be done very eii'ectively. The flange M at the bottom of the air-conduit spreads the flames through the fire-box. For the purpose of so spreading the flames the vaporizing-plate 12 is also of peculiar construction. On one side it has an annular concave portion and a central convex portion, the reverse on the opposite side. It is reversible, so that either side may be used uppermost. The central portion is not higher than the rim, so that it will be stable in either position. If used in the position shown in Fig. 2, the flames will be more concentrated than if used in the reverse position. In the latter case the flames would be considerably spread. This construction is also useful to conform to the difference in burning heavy distillates or light distillates. The plate is used in the position in Fig. 52 for burning heavy distillates and in thereverse position for burning light distillates. This construction is also of advantage, as it enables the vaporizing-plate to be tilted slightly to deflect the flames in either direction. Thus by insuring the short bar of iron underneath the edge of the burnerplate nearest the stove door said burnerplate may be raised on that side, directing the flames to the other end of the lire-box.

through the opening closed by the stove-door. This is important in two ways-it admits of the burner being placed in an ordinary stove without there being any difficulty in starting the tire through the stove-door and it also allows the person in charge of the stove to readily watch and inspect the dropping of the oil to ascertain whether it is dropping too slow or too fast.

In certain cases it may be desired to have the air-draft enter from below instead of from the side, as shown in Fig. 1. In such cases the closure 25 (shown in Fig. 4:) is desirable. This is a casting having a central Wall 26 and two lateral walls 27 at right angles thereto, the lateral walls fitting against the sides of the burner below the lip or shelf 19 and the central wall fitting against said lip or shelf. When in this position, access of air to the conduit is shut off except at the bottom.

I claim 1. A hydrocarbon burner comprising a base, an air-conduit supported thereon having a horizontally extending portion opening downward, an oil-pipe in said conduit, and a vaporizing-plate onto which said oil drops, said plate being loosely supported on the base,

and having on one side an annular concave portion and a central convex portion, and the other side beingcurved conversely, the central portion being no higher than the rim, substantially as described.

2. A hydrocarbon burner, comprising a base, avaporizing-plate supported thereon, an air-conduit having a horizontally-extending portion, an oil-pipe in said air-conduit and supported thereby discharging onto said plate, and means for supporting the conduit and. oilpipe adjustably relatively to said plate, said means comprising a vertical flange on the base, a slotted vertical wall on the conduit,-and bolts through said wall and flange, substantially as described.

3. A hydrocarbon burner comprising a base-plate, a conduit supported thereon having a horizontally-extending portion discharging downward onto said base-plate and having also an upper lip or shelf extending in the opposite direction from said portion, said lip or shelf being cast with transverse grooves, whereby sections of the same may be broken off to adjust the size thereof, substantially as described.

4. A hydrocarbon burner comprising a base, an air-conduit having a depending lug and a horizontal air-passage opening downward, an oilpipe passed through and supported by said lug, extending in said horizontal portion and discharging over said downward opening, and a vaporizing-plate onto which the oil drops, substantially as described.

5. A hydrocarbon burner comprising a base, an air-conduit having a depending lug ITO and a horizontal air-passage opening downward, an oil-pipe passed through and supported by said lug, extending in said horizontal portion close to the upper Wall thereof, and discharging over said downward opening, and a vaporizing-plate onto Which the oil drops, substantially as described.
