To all whom it may concern:

Be it known that we, FRED 0. Born and CHARLES F. LITTLEJOHN; citizens of the United States, residing at New Haven, in the county of New even and State of Connecticut, have invented a new and useful Improvement in Hydrocarbon-Burners; and we do hereby declare the following, when taken in connection with the accompanying drawings and the characters of referencemarked thereon, to be a full,

clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Figure 1 a top or 'plan view of a hydrocarbon burner constructed in accordance with our invention.

This invention relates to an improvement in hydrocarbon burners particularly adapted for use in burning kerosene oil, the object of the invention being to provide a burner which may be inserted into the ordinary fire-box of a cook stove or range, heating stove, furnace or other device in which coal or wood is commonly used; and the invention consists in the construction hereinafter described and particularly recited in the claims.

In carrying out our invention we employ a base-plate 6 preferably of cast metal and corresponding in dimensions to the number of burners used. our invention we have shown a device comprising two burners.- This base-plate is supported upon an open rectangular casing 7 provided at its lower edge with an outwardly projecting flange 8 adapted to rest upon the grate in the usual fire-box and so as to support the base-plate above the grate and provide a passage for air drawn upward through the grate. The base-plate is formed around its edge with an upwardly.

projecting flange 9 and with burner openings 10, the openings being surrounded by collars 11. The base-plate is also. formed with tubular openings 12 through which feed pipes 13 extend, these pipes leading Specification of Letters Patent.

through the ordinary dampers 14in the front of the stove to a tank 15. Resting on the base around the edge of the collars 11 is a housing 16 forming a mixing chamber above and aroundthe collars. These housings-are formed at their lower edge with lugs 17 by which the'housing may be secured to the base-plate 6. by screws 18. The lower edges of these housings are formed with notches 19 'to permit air to be drawn into the mixing chamber. These housings are formed attheir upper ends Patented net. flit, ilht o Application filed October 22, 1918. Serial No. 259,223. i

with chimneys 20 smaller in diameter than the diameter of the housing so as to form annular priming channels 21 for the purpose as will hereinafter appear. The feedpipe 13 extends upward over the mixing chamber and is formed with a coil which extends down through the mixing chamber and terminates in an upwardly extending burner tube 22 provided at its upper end with a burner nipple 23. Over the coil in each mixing chamber is a distribu-ter 24 which is suspended on an arm 25 mounted in a post 26 which is secured to the baseplate 6 between the burners. The device is placed in the firebox of an ordinary cook stove as indicated in Fig. 5 of the drawings upon the grate-bars therein, or it may be placed in any furnace or other fire-box where required. Upon the flange 8 may be placed any packing, such as ashes, so as to cut off any upward draft through the grate which will all be deflected upward through the casing 7. The pipe from the fuel supply is then opened to permit the fuel to flow to the burner and one or more of the burners may be used as is required. The heat from the burner vaporizes the fluid in the feed tube as it passes to the burner tip so that it emerges in the form of gas, and this gas is spread by the deflector so as to cover the heating surface of a range or furnace. In first starting the burner, it may be desirable to place some kerosene or other burning fluid in the priming channel 21 so as to heat the burning fluid as it first comes to the burner tip. This in- -wardly set priming channel also restricts ings 19 so as. to further amist in combustion and preferably, and as shown, the upper inner of the chimney or 21th cup will be formed with notches 2 through which flames will 'be directed to the upper part of the coil. It will thus be seen that a burner for liquid fuel, such as kerosene, "is; provided, which is readily adapted to be placed in an fire-box without requiring any change in the structure of the apparatus into which it is placed.

We claim 2- 1. A hydrocarbon burner comprising a plate formed with an opening, a mixing chamber around said opening, said mixing chamber formed at its upper end with a priming cup, a feed pipe extending over said chamber and downward through the chamber inthe coil, said pipe terminating in a centrally arranged burner tip.

2. A hydro-carbon burner comprising a plate formed with an opening, an upwardly projecting collar around said opening, a mixing chamber casing mounted on the plate around said collar, said mixing chamer casing formed in its lower edge with notches and at its upper end with a priming cup, a coil within said mixing chamiaeae a ber 1 to the source of supply, and a burnerconn with the lower end of 3. A hydro-carbon burner comp baselate formed. with an opening, an upward y projecting collar around said opening, an opencasing u on which the said base is supported, sai base also formed around its outer edge with an upwardly projecting flange, a mixing chamber caeing secured to said base around said collar, said mixing chamber casing formfi in its lower edge with notches, and at its upper edge with an inset annular priming cup, a.

0011 in said mixing chamber, said 0011 connected with the source of supply, a burner connected with the lower end of said coil,

and a distributor plate mounted above-the
