HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 623,518, dated April 25, 1899.

Application ned May 31,1898. SerialNo. 682.150. (No model.)

To all whom, it may concern:

Be it known that I, EDWIN F.. ORooK, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Hydrocarbon-Burners, of which the following is a speciication.

The common practice in starting hydrocarbon-burners has been to heat the generator by burning oil in an open pan under it, and while this is a quick method of getting the lire started it is quite objectionable on account of the disagreeable odor of the oil which unavoidably escapes, and because of the eX- cessive production of soot, which collects on the burner and inside of the stove, making all parts reached by it smutty and dirty.

One object of this invention is to provide means whereby the initial heating of the generator can be accomplished without odor and smoke in perhaps a little longer time than by the open-pan method, but also in which the open-pan method can be quickly employed whenever quicker results are essential,

Another object is to distribute the oil uniformly over a larger area of the pan than heretofore, and the object also is to facilitate the transmission of heat from the walls to the oil on the inside of the generator.

The object of the invention also is to provide means whereby the flame and heat from the burning vapors can be controlled and directed at will against the stove-top or downk toward the oven, as the circumstances may require.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure l is a detail in vertical section of my improved burner, showing the pipeconnections for the supply of oil and the transfer of the vapors. Fig. 2 is a detail in side elevation, partially in section, of the upper half of the generator and superimposed parts. Fig. 3

' is a horizontal section of the generator on the dotted line 3 3 looking inthe direction of the arrows, and Fig. l is alike view of the oilpan on the dotted line 4 et. Fig. 5 is a view, on a larger scale, of the oil-pan and initialheating apparatus. Fig. 6 is a side elevation of the hood which covers the lamp under the generator, and Fig. 7 is a section of saine on the dotted line 7 '7 of Fig. G looking in the direction of the arrows.

A is the tank which contains the oil to be used, and which oil will preferably be one of the residuals of petroleum after the gummy properties and most valuable commercial ingredients of the crude oil have been removed.

B is the retort or generator, which is oval or circular in outline and is flattened at the sides and in many respects is similar to other generators heretofore used for the same purpose. Ithas the central walled opening B and is supplied with oil from the tank A through the pipe A. The latter has the cock a, by means of which the oil is turned on or off. The oil is vapor-ized in the generator B, and the vapors are carried down through the pipe In2 and are discharged at the lower end of the opening B', where they mix with air and pass up through the opening into the spreader O. The spreader O is a removable conical cap with a vertical downwardly-projected annular iiange O', which is provided with the slots or kerfs c, through which the mixed vapor and air introduced into the concavity of the spreaderissues. The ignition of the gases takes place outside of the kerfs, and the heat generated raises the temperature of the generator-walls,thereby causing the oil contained in the generator to become heated to volatilization. This is encouraged by the formation of the concentric Walls Z), which conduct the heat down into the oil, and by the radial ilanges b', integral with the top, bottom, and sides of the generating-chamber. The latter by being located immediately under the flame of the ignited gas assistV very materially in conducting the heat into the oil. Radial ianges b2 around the walls of the central opening B are specially advantageous in the initial heating of the generator, as will hereinafter more clearly appear.

In cooking on top of the stove it is desirable that the gas-Haine and heat be directed against the lids of the stove, and for that reason the annular ange D', a suitable distance from the kerfed cap, is provided. For baking, roasting, and such operations as require the use of the oven it is desir-able that the heat and ame be directed downward in the direction of the oven, and to provide for this I make a depression in the outer margin ICO of the generator-top to receive an annular plate D, and I provide suitable means for elevating this plate until its under side is above the kerf-terminals of the spreader, thereby permitting and forcing the flame to pass between the plate and the top of the generator. The contour of the under side of the plate D is such as to direct the llame in a downward direction. In the drawings I have shown the cams or eccentrics d for giving the proper elevation to the plate D; but other means can be adopted without departing from the spirit of this invention, the essential feature of which is the adjustable plate itself and not the means for securing that adjustment.

I will now describe the means by which the initial volatilization of the oil is accomplished in starting the action of the burner.

E is the oil-pan, which has a central opening surrounded by an upwardly-projected wall or line E', at the base of which is an outside annular concavity or depression cof considerable depth to receive and hold a supply of oil, which is conveyed to it through the pipe A2, which is a branch from the pipe A', as shown in Fig. l of the drawings. It is provided-with the cock d2, by which it is opened or closed at the will of the operator. Surrounding the line E and resting on and bolted to the bottom of the pan is a plate F, having a central opening of course, and surrounding this opening is the vertical wall or flue F', the diameter of which is greater than the outside diameter of the Iiue E' toa degree sufficient to provide space for a wick G, which is placed between the two i'lues. This wick will be of non-combustible material, preferably such as asbestos, and its lower end will rest in the oil-depression c, from which by capillary action the oil will be diffused throughout the wick and will be ignited at the top of the latter. The wick will be fastened to a metal band G. The two ends of an adjusting-rod g will be fastened to diametrically opposite sides of the band, and the middle portion of the rod will be bent over the flue E' and carried down inside of the flue and toan accessible point below it, where it can be manipulated to raise and lower the wick. The plate F will have under-side radial grooves j", forming channels through which an excess of oil discharged into the depression e will overflow into the pau. The plate also has outside marginal lugs projected upwardlyor aeontinuous marginal flange, as shown at f in the drawings, to which the base of a truncated conical hood II is secured by bolts, rivets, or otherwise. This hood is bolted in like manner to lugs depending from the underside of the generator. The front of the hood will be cut away to permit access to the wick when it is de sired to light the oil on the latter, and this opening-is closed by a sliding door H. An air-space 71. between the hood and the generator will be provided, and the sliding door may be made to form a closure for this opening also, if desired.

IVhen the oil on thewick is ignited, the iiame will have center draft as well as outside-air supply, and the hood and walled opening through the generator will act as a flue to insure complete combustion of the carbon in the oil and prevent the formation of soot. The escape into the room of the disagreeable oily smell will also be prevented.

Experience will indicate the proper amount of oil to be admitted into the cavity c, and when the oil is all consumed the lire on the wick will go out.

Should it be desired to secure quick action in starting the generation of gas in the generator, a supply of oil may be admitted through the pipe A2 to flood the bottom of the pan E, and the oil will then be ignited in the pan in the usual way. To insure a more even diffusion of the oil in the pan, I prefer to slope the bottom of the latter upwardly toward the center and provide a series of annular ribs E2, which will retain a portion of the oil and allow only the overiiow to pass down to the next rib, and so on. The walls I) and anges b carry the heat up into the oil from the bottom of the generator in the same manner as the heat is carried down from the top after the burner is working normally, and the ilanges b2 around the center opening conduct the heat into the oil from the center tube. Transverse openings b3 permit free circulation of oil around the base of the vaportube.

Having thus fully described my invention,

what I claim as new, and wish to secure by Letters Patent of the United States, is
