HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed January 27, 1905. Serial No. 242,337.

To aZZ whom it may concern.-

Be it known that 1, Cinemas R. HERRING- TON, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented certain new and useful Improvements in Hydrocarbon-Burners; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of hydrocarbon-burners especially intended for use in connection with the heavier liquid hydrocar- .bonsas, for instance, crude oiland which are designed more particularly for cookingstoves and other like structures.

The object of my invention is the production of an effective, simple, and inexpensive burner of that type in which an initial ignition of a limited quantity of oil is intended to furnish heat to a chamber within its sphere of influence to generate combustible vapor from a body of oil maintained in said chamber, the burner being quickly applied to the fire-box of an ordinary cooking stove or range and readily removed therefrom for the purpose of renewal or repairs.

The essential features of the invention reside in the generating-chamber for the combustible vapor and the means for supplying air to the burners extending from the said generating-chamber.

To comprehend the invention, reference should be had to the accompanying sheet of drawings, wherein- Figure 1 is an end view of an ordinary cooking-stove, partly broken away and sectioned, the hydrocarbon burner being illustrated within the fire-box of the stove, the supporting-plate for said burner being partly sectioned. Fig. 2 isalongitudinalsectionalview of the burner removed from the stove. Fig. 3 is a plan view of the burner, and Fig. 4 is an end view of one of the air-supply pipes or tubes.

The numeral 1 designates an ordinary cooking-stove or other like structure, and 2 the fire-box thereof, within which fire-box is located the supporting-plate 3. This plate is cast with an upwardly-projecting rectangular flange 4:, which forms an open chamber 5 for the reception of the oil used for initial firing.

The supporting-plate 3, which serves as a carrier for the burner, is supported in the fire-box 2 in any suitable manner. In practice it will rest upon the ledges 6 in the firebox, taking the place of the usual grate, which is removed. In the supporting-plate 3 is made a central aperature 6, which is surrounded by an upwardly-extending circular flange 7. The oil supply or feed pipe 7 ente'rs through the ash-pit opening and turning upwardly extends through the downward extension 8 of the vaporizing-chamber 8, projecting well up into said chamber, Fig. 2 of the drawings. This vaporizing pan or chamber 8 is secured to the supporting or carrier plate 3, its depending extension 8 fitting within the circular flange 7 upwardly projecting from the said supporting or carrier plate 3.

Upon the vaporizing pan or chamber 8 is a cover 9, which forms a gas or vapor receiving chamber 9, said cover being provided with a superheater or dome 10. This dome receives and holds the vapor delivered into the chamber 9, so that the same may be superheated by the flame of the burner, and acts to maintain a constant pressure onto the gas or vapor within the chamber 9. From the cover 9 laterally extends the burner-tips 11, through which burners the vapor or gas escapes from within the chamber 9. These tips are in line with the air-supply pipes or tubes 12 12, which pipes or tubes are of such size as to permit of suflicient air flowing therethrough to cause proper combustion. The lower ends are fitted within the openings 13 13, formed in the supporting or carrier plate 3, the air entering therein from the ash-pit 14. or from beneath the said supporting or carrier plate 3.

The cover 9 is held against displacement by means of the depending lugs 15, which embrace the outer wall of the chamber 8 when the said cover 9 is fitted onto the pan or chamber 8'. Between the upper surface of the vaporizing pan or chamber. 8 and the lower edge of the cover 9 an exit-space 15 is formed. Through this space the oil overflowing the chamber 8 escapes and flows into the open receiving-chamber 5, which oil delivered therein serves for the initial firing. I have found that a comparatively close fit between the cover 9 and the upper surface of the vaporizing pan or chamber 8 is the better practice, as even by the ordinary inaccuracies of the metal an exit-space is left which will permit the escape or the overflow of the oil from within the pan or chamber 8.

The oil is supplied through the pipe 7 until it fills and overflows the vaporizing pan or chamber 8, the overflow falling and trickling down into the receiving -chamber 5 l/Vhen a sufficient quantity is in the chamber 5, the supply of oil is temporarily cut off by the valve 16 and the oil in the chamber 5 ignited. The flame from the burning oil heats up the chamber 8 and causes the vaporization of the oil therein. The vapor or gas thus generated in the vaporizing-chamber 8 flows upward into the chamber 9 and escapes therefrom through the burner-tips 11 and is ignited by the flame of the initial firing. The supply of oil is then resumed by the opening of the valve 16 and the required quantity of oil maintained in the vaporizing chamber or pan 8, which is thereafter vaporized by the high temperature caused by the burning flame. As the chamber 9 becomes filled with the generated gas or vapor the same escapes or flows into the dome 10 and is superheated therein by the burner-flame, which completely envelops the dome 10.

The ignition of the vapor or gas escaping through the burner-tips 11 causes an upward air-draft through the air pipes or tubes 12 12', which supplies the required oxygen for perfect combustion. Y

The entire burner is readily separated and taken apart, inasmuch as the parts are not required to be bolted one to the other, and the said burner can be easily placed into and removed from the fire-box of the stove.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. A hydrocarbon-burner comprising a carrier or supporting plate having a central aperture therein surrounded by an upwardlyextending circular flange, an open receivingchamber in said plate for the reception of oil for initial firing, a vaporizing chamber or pan provided with a depending extension which fits within the upwardly-extending circular flange of the carrier or supporting plate, an oil-feed pipe passing upwardly through the said depending extension and extending well into the vaporizing pan or chamber, a cover fitting onto the said pan or chamber and forming a gas-receiving chamber, an escape-passage between the cover and the vaporizing pan or chamber for the outlet of an overflow of oil, air-supply tubes extending upwardly from openings in the carrier or supporting plate, said tubes terminating at diametrically opposite points outside of the gas-receiving chamber and supplying to the burner the req uisite air for proper combustion, and outlets formed in the wall of the gas-receiving chamber for the escape of the generated gas.

2. A hydrocarbon-burner comprising a carrier or supporting plate, a vaporizing-chamber connected thereto, means for supplying oil to said chamber, a gas-receiving chamber communicating therewith and secured directly to and immediately above the vaporizingchamber, an outlet between the said I chambers for permitting the escape of an overflow of oil from within the vaporizing-chamber,

said overflow serving for an initial firing, a

superheater directly connected to and communicating with the interior of the receivingchamber for the vapor or gas, burner-tips extending from the vapor-receiving chamber, and means for supplying air to the burners for creating proper combustion, said means consisting of air-tubes leading from the supporting-carrier and terminating at point directly opposite the burner-tips.

3. A hydrocarbon-burner comprising a carrier or supporting plate, a vaporizing-chamber connected thereto by means of a depending extension fitting within a circular flange upwardly projecting therefrom, means for supplying oil through the depending extension to the interior of the said chamber, a gas-receiving chamber secured immediately above and communicating with the interior thereof, an outlet between the said chambers for permitting the escape of an overflow of oil from within the vaporizing-chamber, said overflow serving for an initial firing, a superheater connected to the upper surface of and communicating with the interior of the receiving-chamber for the vapor or gas, burnertips extending from the vapor-receiving chamber, air supply tubes extending upwardly from openings in the carrier or supporting plate, said tubes supplying to the burner-tips the requisite air for proper combustion.

In testimony whereof I have hereunto affixed my signature in the presence of witnesses.
