HENRY o. DAVIS, or TE RRE HAUTE, INDIANA.

HYDROCARBON-RETORT VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 388,843, dated September 4, 1888.

Application filed February 23, 1888.

To all whom it may concern.-

3e itknown that I, HuNRY O. DAVIS, a citizen of the United States, residing at Torre Hautc, in the county of Vigo and State of Indiana, have invented a new and useful Hydrocarbon-Retort Vaporizer and Burner, of which the following is a specification.

My invention relates to an improvement in that class of hyd roearbon-retort Vaporizers and burners which are adapted for use in an ordinary stove for domesticpurposcs,and in which the vapors of water and of a hydrocarbon |luidas petroleum or any of its liquid derivativcs are simultaneously formed, combined, and burned.

The object of my improvement is to provide a convenient apparatus for the purpose mentioned, which may be easily and cheaply constructed, and in which the vapors of water and hydrocarbon are brought together at or very near the point of ignition, all as hereinafter fully described.

The accompanying drawings illustrate my invention.

Figure l is a plan. gitudinal section.

A. is a strong hollow cylinder, of cast or wrought iron,having closed ends,and forming a reservoir for the oil-vapor.

I; is the water-retort.

(J is the oil-retort.

Itetorts l; and U consist of short sections of iron pipe screwed into but only part way through the ends of the reservoir, and having their outer ends closed by screw-caps (Z and 0. Communication is established between the oilretort U and the reservoir A through small perforations g in the end of the reservoir.

F is the mixing-chamber, which consists of a short hollow cylinder which is attached to the under side of the reservoir and connects with the interior thereof by the short pipe 11. partitionyi, having small perforationsj, is arranged across the interior of chamber F, and immediately above this partition are branch pipes It: and /,which lead to the burners m and a.

It will be observed that the diaphragm i is situated between the steam-pipe p and the burners, and also between the steam-pipe and the pipe 7', which leads the hydrocarbon vapor Fig. 2 is a central 1011 Serial No. Qfi4,s03. (No model.)

into the mixing-chamber. The reason for this arrangement is to prevent the steam, which ordinarily is under greater pressure than the hydrocarbon vapor-,from blowing back or pre venting the said vapor from being fed freely to the burners or from blowing out the flame, as otherwise might occur were the diaphragm not interposed, as shown.

. Zurners m and a consist of short sections of pipe, having their outer ends closed and their upper sides provided with narrow slots 00,211- ranged at such an angle as to throw jets of flame against the retorts and reservoir.

The lower end of chamber F is connected with the water-retort B by a pipe, 1). Pipe 1t connects retort B with a source of water-sup ply. Pipe S connects retort O with a source of oil-supply. For the purpose of holding a small quantity of oil or other fuel to firstheat the retorts, and also to furnish a convenient support for the apparatus, I provide a shallow pan, '1, having a central hollow hub, a, in which.the mixing-chamber fits loosely and is held rigidly therein by a set-screw, o.

The operation of my device is as follows: Rctorts B and U and the reservoir A having been heated by fuel placed temporarily in the pan T, oil is admitted to retort G, and being vaporized the vapor passes through perforations 1 g to the reservoir, and from thence through the mixing-chamber F and branch pipes k and l to the burners m and a, where, escaping from slots 0, it is ignited and burns with a. smoky flame. \Vater is now admitted to retort l and the vapor therefrom, being superheated,passes through pipe 1) to the mixing-chamber, where, passing through the perforations in partition i, it mingles with the vapor of the oil, and the flame becomes clear and intensely hot,and,rising around and above the reservoir and retorts, continues the op eration so long as oil and water are supplied, and the surplus heatbecomcs available tordo mestic purposes.

lleretofore in this class of retort-vaporizers the oil and water vapors have passed directly to the reservoir by substantially equally direct routes,and have there been mixed before passing to the burners. by joining the two va pors in the small mixing'ehamber very near IOO the point of escape and ignition the oil-vapor forations 1 the mixing-ehamber arranged beis not overcharged with water-vapor and a cleaner and hotter flame is the result.

I claim as my invention- 1. The combination of the reservoir having one side perforated,the water-retortand the oilretort supported by the reservoir, the latter communicatingtherewiththroughtheperforations through its side,the mixingchambersituated below the reservoir and communicating therewith through a short pipe, h, and provided with a perforated diaphragm extending across it between its ends, the pipe connecting the water-retort with the mixing chamber on the side of the diaphragm opposite that on which pipe h enters, and the burners, substantially as described.

2. The combination of the reservoir having one side perforated at 1 the water-retort and the oilretort extending laterally in di fferent directions from the reservoir, by which they are supported, the oil-retort communicating with the interior of the reservoir through the perlow the reservoir with which it oonnnnnieates, the perforated diaphragm dividing the mixingchamber, the pipe connecting the waterretort with the mixing chamber, and the burners extending laterally from the mixing chamber below and parallel with the oil and water retorts, substantially as set forth.

3. The combination of a tray, T, provided with a hollow hub, the mixing-chamber situated therein, the reservoir situated above the mixing-chamber, the retorts supported by the reservoir above the said tray, pipes whereby communication is established between the retorts and the miXing-elianiber,and the burners communicating with the mixing-chamber and arranged to heat the retorts, substantially as described.
