OIL-BURNER.

SPECIFCATION forming' part of Letters Patent No. 15,227, dated December 2, 1902.

Application tiled March 13, 1902.V Serial No. 98,815. (lio model@ To @ZZ whom t may concern,...-

Be it known that I, FRANK N. VILOQX, a citizen of the United States of America, residing at New Orleans, in theparish ot' `Orleans and State of Louisiana, have invented certain new and useful Improvements in Oil- Burners; and l do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled inY the art to which it appertains to make and use the same.

My invention relates to improvements in oil-burners; and it consists in providing a suitable oil-burner in which the oil is distributed by and consumed from the surface of water.

The invention also consists of certain novel features which will be hereinafter described and claimed. l

Reference is had to the accompanyingdrawings, in which the salue parts are indicated by the same letters throughout the several views.

Figure l represents a plan view of a burner, part of the cover being broken away. Fig. 2 represents a section along the broken line 2 2 of Fig. l and looking in the direction of the arrows. Fig. 3 is an inverted plan View of the annular perforated plate used in the burner, and Fig. 4 represents a section-along the line 4 4L of Fig. l and looking in the direction of the arrows.

Arepresents the shell or body of the burner, which is provided with a flange A', having a vertical ring d. Between the body of the burner and this vertical ring are a number of ribs A2, radially disposed, which ribs are V-shaped, as shown in cross-section in Fig. 1, to form V-shaped troughs d2, with interposed air-passages a3. These V-shaped `troughs a2 open into the liquid-chamber in the bottom of the burner, as shown to the left of Fig. 2.

Through the centerof the body A, l provide a hollow cylinder A0, projecting above the surface of the liquid, as shown in Fig. 2. This cylindrical opening allows a passage upward therethrough of air, and thus prevents excessive heating of the liquid contents of the burner and also supplies air to the burningsurface of the oil.

B represents an annular scattering-plate which slips over this cylindrical center of the somed.

burner-body and rests on a shoulder a. This annular plate is perforated, as at b, the said perforations being conical in theform of inverted funnels for the better scattering of the oil and water passing therethrough.

Oil is fed into the base of the burner through a pipe C from any suitable source of supply, and water is pumped into the base of the burner through the pipe D. lf it be desired to wash out the burner, the valve ol may be `closed and the contents ofthe burner may be drawn olf through the waste-pipe D.

E represents a cap, perforated as at e, which covers the center of the burner and serves to deflect outward the air passing up through the cylindrical aperture A", at the same time to contine the combustion to the annular space outside ot said cap and above,

the V-shaped troughs a2. omitted, if desired.

F represents a pipe to carry ot the liquid contents of vthe burner above a certain level, which may be used when the oil and Water become too intimately mixed, it being preferable to have the oil mainly lioating on the topof the Water at the time it is being con- Bydrawing oft the oil and Water through the pipe F above the level of the orilice ol' said pipe fresh oil and water may be injected through the pipes C and D, and thus the proper proportions and admixture may be secured. A

The supply of oil and water may be regu- This cap may be 4lated by valves controlling the pipes C and D or in any other convenient Way.

The operation of the device is as follows: Oil and Water are fed in through the pipes C and D and rising together, the oil principally above the water, will pass through the opening d upward beneath the cap E. Thence spreading laterally the oil and Water will flow into the V-shaped troughs a2, and the oil be ing ignited by a smallpiece of Waste soaked in oil or in any other convenient Way coinbustion isstarted. Air rises through the inlets as and supplies the necessary .oxygen to convert the carboniccoxid of the-llameinto carbon dioxid and to ca'use perfect colnbustion. The air coming up through the central passage A0 serves to prevent the liquids in the burner from becoming toorhot prior to combustion ,thus preventing the evaporation IOO ofan-excessiveamountofwater. At thesame time some of this air passes under the edges of the cap and over the oil in the V-shaped troughs, thus further aiding in thecombustion.

While burning, the air evaporates more or less of the water, and the steam so formed in passing through the boiler or over the other object to be heated gives up a large part of its heat. The water thus not only serves as a medium for finely distributing the oil over a wide surface from which surface the oil is consumed, but it also serves to lessen the intense heat of the burning oil, which is objectionable inmost of the uses to which such burners are applied.

By the herein-described apparatus complete combustion of the oil is secured, and a cheap, sim ple, and effect-ual apparatus is provided in which the desired result is economically obtained. Y

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. An oil-burner comprising an annular chamber with air-passage through the center thereof, the said chamber having a narrow base and au enlarged upper portion provided with a series of radial troughs to receive the liquid, with air-passages between said troughs, with means for simultaneously feeding oil and`water into the base of said chamber, whereby the oil is caused to pass through and spread out over the surface of the water in the enlarged portion of said chamber, substantially as described.

, 2. An oil-burner comprising an annular chamber with air-passage through the center thereof, the said chamber having a narrow base and an enlarged upper portion, provided with a series of radial troughsto receive the liquid, with air-passages between said troughs, with means for simultaneously feeding oil and waterinto the base of said chamber, whereby the oil is caused to pass through and spread out over the surface of the water in the enlarged portion of said chamber and a scattering-plate arranged in said chamber below the normal surface of the oil, substantially as described.

3..An oil-burner comprising an annular chamber with an air-flue through the center thereof, the said chamber having a narrow base and au enlarged upper portion provided with a series of radial troughs to receive the'liquid, with air-passages between said troughs, a cap above said air-flue and extending over the inner ends of said troughs, and means for simultaneously feeding oil and Water into the base of said ohamber,whereby the oil is caused to pass through and spreadout over the surface of the water in the enlarged portion of said chamber, substantially as described.

4. An oil-burner comprising an annular chamber with an air-flue through the center thereof, the said chamber having a narrow base and an enlarged upper portion, provided with a series of radial troughs to receive the liquid, with air-passages between said troughs, a cap above said air-flue and extending over the inner ends of said troughs, and means for simultaneously feeding oil and water into the base of said'chamber, whereby the oil is caused to pass through and spread out over the surface of the water in the enlarged portion of said chamber and a scattering-plate arranged in said chamber below the normal surface of the oil, substantially as described.

5. An oil-burner provided with a central chamber, with radial troughs exterior to and connected to said central chamber, air-passages opening upward between said troughs,

a cap above said chamber and extending over the inner ends of said troughs, and means for supplying oil and water to the base of said chamber, substantially as described.

6. An oil-burner provided with a central annular chamber with a vertical air-passage therethrough, radial troughs exterior to and connected to said central chamber, air-passages opening upward between said troughs, a cap above said air-flue and extending over the inner ends of said troughs, and means for supplying voil and water to the base of said chamber, substantially as described.

7. An oil-burner provided with a central annular chamber with a vertical air-passage therethrough, radial troughs exterior to and connected to said central chamber, air-pas.- sages opening upward between said troughs, a scattering-plate below said troughs, a cap above said air-due and extending over the inner ends of said troughs, and means for supplying oil and water to the base of said chamber, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
