HYDROCARBON-VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 400,313, dated March 26, 1889.

(No model.)

To to whom it may concern.-

Be it known that I, HENRY C. DAVIS, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Improvement in Hydrocarbon -Vaporizers, of which the following is a specification.

My invention relates to a hydrocarbonburner having certain novel features of c011- struction and arrangement, to be hereinafter pointed out, and which is particularly adapted for use in connection with a'stove.

The accompanying drawings illustrate my invention.

Figure 1 represents a view in perspective of the generator and burner. Fig. 2 repre sents a transverse section of the same, on a smaller scale, arranged for use in the fire-pot of a stove.

A and B represent a pair of retorts, formed preferably of wrought-iron tubes, having their ends closed by heads welded therein. retorts are provided with supply-pipes c and d, which lead, respectively, to the water-tankl and the oil-tank m, and theirinteriors are connected at one end by the pipe 6. Above the 'retorts A and B is a cylindrical reservoir, F,

which is also formed,preferably, of wroughtiron tube having theends closed by welding a head therein. Theinterior of reservoir F is connected with the interior of retort B, opposite to that end of said retort which is con- From the other end of reservoir F a pipe, 1', passes downward and then horizontally underneath, between, and parallel with the retorts A and B. The lower or horizontal portion of pipe 45 is provided on its upper surface with a series of narrow longitudinal slots, j, and its extreme end is closed. Arranged between and slightly above the retorts A and B is a sheet of metal, forming a deflector, 70.

It will be understood that, the retorts having been first heated by'a fire built beneath them, water is admitted to retort A and oil to retortB through the supply-pipes c and (Z. The water, being vaporized and the vapor be ing superheated in retort A, passes through the pipe 6 to the retort B, where it unites with the vapor of the oil, and the gas thus formed passes through pipe h to the reservoir F, where it is still further heated, and, issuing Said thence through the pipe 2', is discharged and burned at the slots j, thus making the process continuous.

It is found necessary to the attainment of the best results in this class of vaporizer that the proportions of water and oil admitted to the respective retorts be uniform. For the purpose of effecting this result, having previously determined the proper relative proportions of water and oil, I arrange the valves '17, and o in the supply-pipes c and d, so that their stems may be connected by a pair of gears, 19 and r, having the same relative proportions, so that upon either valve-stem being turned to open the valve the other Valve is also turned so as to admit the proper pro portionate amount. It has also been found that in this class of vaporizer the sudden admission of cold air to the stove in which they were arranged has so lowered the temperature of the gas as to cause it to smoke badly in burning. For the purpose of avoiding this difficulty, and also to avoid the loud noise of the escaping gas commonly found in these burners, I arrange the vaporizer in the firepot of a stove, as shown in Fig. 2.

T represents the grate in the bottom of the fire-pot U. The vaporizer rests on this grate and is surrounded by a sheet-iron casing, 12, (indicated also in dotted lines, Fig. 1,) which is open at the top and bottom, the lower end of the casing resting on the grate, and there being an opening, t, in the side, through which kindlings may be laid on the grate beneath the generator. The space above and around the generator, between it and the casing o, is now filled with irregular bits of slag, w, firebrick, or other like incombustible and refractory material, the object being to prevent the too rapid escape of the gas, to distribute the flame over a large surface, and to retain the heat about the retorts, the receiver, and their connections. By this means all parts of the generator are kept at a uniform and high temperature and a perfect and nearly noiseless combustion of the gas is secured.-

The casing *0, when burned out, may be easily removed and cheaply replaced, thus saving the sides of the stove.

I claim as my invention 1. The combination, with a stove having a grate, of a hydrocarbon-burner, a vaporizingretort, a steam-generating retort, and a mixing-chamber, all situated within the fire-pot of the stove, a removable metal casing surrounding the said parts and resting on the grate, and having an opening, I, in its side adjacent to the grate, whereby heat from burning material upon the grate will pass through the said opening and heat the said parts when it is Wished to start the burner, and a mass of refractory material Within said casing, substantially as described.

2. In a hydrocarbon-burner, the combination of the Water and oil retorts A and 13, lying side by side, the burner situated below the HENRY C. DAVIS.
