UNITED STATES PATENT OFFICE.

HARRY O. HORNISH, OF LOS ANGELES, CALIFORNIA, ASSIGNOR OF ONE- HALF TO WV. W. ROBBINS, OF LOS ANGELES, CALIFORNIA.

HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Sept. 18, 1906.

To all whom it may concern:

Be it known that I, HARRY O. HoRNIsH, a citizen of the United States, residing at IJOS Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention primarily relates to a burner designed to burn the lightest grades of crude etroleum and the by-products from petroleum distillate by the aid of steam and air; and the object thereof is to produce a simple and efiicient burner for that purpose which will generate the re uired amount of steam for such purpose wit out the use of a separate steam-generating apparatus therefor. I accomplish this object by the burner described herein and illustrated in the accompanying drawings, in which Figure l is a side elevation of my burner. Fig. 2 is a vertical central section with a part in elevation.

In the drawings the base-plate 3 is provided, preferably in the center thereof, with an upwardly-projecting draft-tube 4E. Surrounding the draft-tube is an annular ring 5, which forms the oil-channel 6. The outer edge 7 of the base projects u wardly and forms the starting-channel 8. A? supply-pipe 9, connected to a suitable water-supply source having a regulating-cock thereon, (source and cock not bein shown,) is preferably connected through t e starting-chan nel with the annular chamber 10, which will be designated as the "steam-chamber of the burner. Leading, preferably, from the central portion of the steam-chamber, and preferably from a point opposite the inlet of the water thereto and preferably passing downwardly through the starting-channel and then passing inwardly and across the draft-tube, is the steam-pipe 11, which has a plug 12 in the end thereof, which plug may be removed when desired to clean out any sediment that may settle in the steam-pipe.

In the" upper part of the steam-pipe and below the center of the draft-tube is a steam port 18, which is controlled by the needlevalve 14:, whose stem 15 asses in threaded contact throu h cap 16, which cap is screwed upon a branc 17 of the steam-tube. The

stem of the needle-valve is provided with an operating-handle 18. Opening into the oil- 0 annel and connected with a suitable source of supply (not shown) is the fuel-supply pipe 19, having a regulating-cock (not shown) thereon to regulate the supply of fuel. 7 A removable cover 20 rests upon the inner portion of the steam-chamber and compels the products of combustion to pass outwardly between the steam-chamber and the startingchannel.

In the operation of my burner after it is set .in the fire-box of a stove or furnace 111 such manner that there is no draft upwardly through the bottom of the fire-box except.

such as passes through the draft-tube of the burner and the water-supply being shut off, a supply of liquid fuel is admitted to the oil and starting channels, and when the starting-channel is partially filled the fuel-supply is turned off, and the fuel in the startingchannel is ignited in the usual manner. By the time the fuel in the oil and starting channels is burned up the steam-chamber and base have become heated to such an extent that the burner is ready for operation. A small supply of water is then admitted to the steam-chamber and a small quantity of fuel is admitted to the oil-channel. The water is generated into steam and passes out through the port in the steam-pipe and is projected upwardly through the draft-tube, drawing therethrough a greater quantity of air than would pass therethrough under natural draft conditions. The fuel as it enters the oilchannel vaporizes and unites with the steam and air and passes upwardly between the steam-chamber and starting-channels as an inflammable vapor and burns in a blue flame around the steam-chamber, thereby keeping the steam-chamber and the base of the burner in a highly-heated condition, whereby the water and liquid fuel are converted into vapor as soon as they reach the heated parts. As the cover 20 is removable, access is had to the fuel-channel and starting-channel, so that they can be readily and easily cleaned out when desired. The connection of the steam-chamber may be made in any suitable manner, and the steam-pipe may lead therefrom to below and across the drafttube from any other point than that shown, but I prefer the construction shown, as the fittings used form a support for the steam-chamber. Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. A hydrocarbon-burner comprising a base provided with an upwardly-projecting draft-tube and having upturned edges, said upturned edges of said base forming a channel around the draft-tube; a fuel-supply opening into said channel; a chamber above said base-plate; a pipe leading from said chamber downwardly and inwardly across the center of the draft-tube, said pipe having a port therein in alinement with the center of the draft-tube; a closure for the space between the inner walls of said chamber; and means to supply said chamber with water. v

2. A hydrocarbon-burner comprising a base provided with an upwardly-projecting central draft-tube and upturned edges, said upturned edges of said base forming a channel around the draft-tube, an annular ring atfixed to said base and surrounding said drafttube; a fuel-si1pply opening into the channel between the draft-tube and annular ring; an

annular chamber above said base-plate; a pipe v leading from said chamber downwardly and inwardly across the center of the draft-tube, said pipe having a port therein in alinement with the center of the draft-tube; a closure for the space between the inner walls of said chamber; and means to supply said chamber with water. 7

3. A hydrocarbon-burner comprising a base provided with an upwardly-projecting central draft-tube and having upturned edges, said upturned edges of said base forming a channel around the draft-tube; an annular ring secured to said base and surrounding said draft-tube; said ringforming a channel around said draft-tube; a fuel-supply opening into said last channel,;'an annular chamber above said base-plate a pipe leading from said chamber downwardly and through the outer channel in the base-plate and then inwardly across the center of the drafttube, said pipe having a port therein in alinement with the center of the draft-tube; a needlevalve on said pipe adapted to control said port; a closure for the space between the inner walls of said chamber; and a water-supply pipe opening into said chamber and passing through the base at a point opposite the pipe leading from said chamber.

In witness that I claim the foregoing I have hereunto subscribed my name this 24th day of February, 1905.
