HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 778,874, dated January 3, 1905.

Application filed January 5,1904:- Serial No. 187,820-

lu (LY/Z 1077,0117, it may concern.-

Diego, in the county of San Diego and State of California, have invented anew and useful Hydrocarbon-Burner, of which the following is a specification.

This invention relates to hydrocarbon-burners, and has for its object to produce adevice of this character simple in construction, easily installed and operated, noiseless in action, and in which the heavier grades of hydrocarbon fuels may be employed.

Another object of the invention is to produce a burner capable of installation without change of structure in an ordinary cook stove or range.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter shown and described, and specified in the claims. 7

In the accompanying drawings, forming a part of this specification, and in which like reference characters are employed to denote corresponding parts, there is illustrated one form of the embodiment of the invention capable of carrying the same into practical operation,

it being understood that the elements therein exhibited may be varied or changed as to shape, proportions, and exact manner of assemblage without departing from the principle thereof.

In the drawings, Figure 1 is a plan view. Fig. 2 is a transverse section of the improved device applied. Fig. 3isa plan view with the spreader-plate removed.

The improved device consists of a relatively shallow priming-tray 10, having its rear side 11 extended above its front side 11 and curved toward the latter side to present a flame-defiector, as shown in Fig. 1, the tray being supported in any suitable manner within the firechamber of a cook-stove, aportion of which is Supported within the tray 10, as by lugs 13, is a relatively large tubular retort, which will preferably be formed of a section of pipe 14:, such as gas or steam piping, and provided with caps 15 16, forming closures for its ends. The retort is positioned above the bottom of the tray 10 and likewise a short distance from its rear side 11, as shown, leaving a relatively larger area of the tray uncovered at the opposite side. Extending upwardly from the retort are burner-nipples 17, the nipples, it will be observed, thus coming above the upper line of the tray '10 and'of its rear side 11, so that free access of air to the nipples is assured. Leading into one of the caps 15 16for instance, the cap l5 is a feed-pipe 18 of relatively small diameter and provided with acontrolling-valve 19, and leading from the pipe 18 is a priming-pipe 20, the latter terminating above the tray adjacent to the side 11* and being provided with a controlling-valve 21.

Extending from the ends of the tray 10 are standards 22 23 for supporting a deflectorplate 2 1, the latter being rendered adjustable upon the standards, as by clamp-bolts 25 and spaced apertures 26. 7

When installed within the fire-chamber of a cook-stove, with the pipes 18 20 extending through apertures in the wall of the stove at one end of the fire-chamber, to start the fire the valve 21 is opened long enough to permit only asmall quantity of the fuel to flow into the tray, which upon ignition heats the retort to a sufficient degree to cause the fuel when admitted through the valve 19 to be vaporized and escape in the form of gas through the nipples 17. As the flame increases in extent and intensity it is deflected by the plate 24: and is caused to play over and above the upper portion of the retort and maintain the latter at a sufficiently high temperature to insure a continuous. and uniform vaporization of the fuel and a correspondingly steady radiation of heat therefrom, so that the con sumption of the fuel is regular and without waste, thus insuring an economical as well as a constant action.

By locating the nipples 17 above the upper .line of the tray 10 the access of air thereto is not obstructed. Hence the gas burns freely and without noise.

By elevating the side 11 of the tray the flame when the kindling-supply flowing from the branch 20 is ignited is thereby deflected and correspondingly increases the rapidityand thoroughness of the vaporization and lessens the tendency to form soot and other sediment. This is due to the fact that the curved side 11 operates positively to prevent the escape of the flame in the priming-pan to the chimney, as it is well known that in all stoves vthe draft is from the front to the rear, and

without the provision of the curved side the flame would have a tendency to pass up the chimney without directly impinging the retort; but by the employment of this curved side the flame is directed against the retort and effects its proper heating before it escapes, the result being that the even and proper heating of the retort is secured and conservation of fuel is effected.

The retort, it will be noted, is relatively large and the feed-pipe l8 relatively small. Hence a correspondingly large vaporizationchamber is provided in which a large supply of the gas is being continuously formed, so that no necessity exists for gas chambers or reservoirs in connection with the device. The vaporization being direct, the fuel is not retarded or caused to pass through circuitous channels, and this renders the burner peculiarly adapted for burning the heavier grades of hydrocarbon or liquid fuel, which require a free and direct flow to the retort and which cannot be burned in devices wherein the fuel is required to flow through intricate or circuitous passages or channels.

The parts may be of any suitable size and of any suitable material and may be modified .in minor particulars, as heretofore noted,

without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed is 1. A hydrocarbon burner comprising a priming tray having a relatively high inwardly-curved rear side, a retort disposed adjacent to the side, and a flame-deflector disposed above the retort. i

2. A hydrocarbon burner comprising a priming tray having a relatively high inwardly-curved rear side, a retort disposed adjac'ent to the side, and a'vertically-adjustable flame-deflector disposed above the retort.

3. A hydrocarbon burner comprising a priming-tray having its rear side extending above its front side and curved inward, a retort supported by the tray adjacent to the rear side, nipples carried by the retort and extending above the sides of the tray, a primingpipe, a feed-pipe, and controlling-valves carried by the said pipes.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
