To all ywho-nt t may concern.

Be it known that I, OTIE C. KiNsoLvINo, a citizen of the United States, and a resident of Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Oil Burners, ofwhich the following is a specification.

This invention relates generally to oil burners especially adapted for use with -oil burning stoves, ranges or the like. The object of the invention is to provide an oil burner of this character wherein the oil and also the air are thoroughly and highly heated immediately prior to their admixture so as to condition both the oil and the gas and thus produce an efficientand thorough combustion eliminating to a large extent deposits of carbon on the burner and surrounding structure andproducing a high degree of heat.

4Another object is to provide a device of this character having these advantages and yet at the same time being of simple and durable construction, reliable and safe in operation and easy and comparatively inexpensive to manufacture and install.

Other objects and advantages of the' invention reside lin certain novelfeatures of the construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had -to the accompanying drawings forming part of this specification, and in which:

Figure 1 is a View in longitudinal vertical section, showing the preferred embodiment of the invention, parts being shown in elevation for the sake of illustration;

Figure 2 is a plan view, showing the air dut and'preheating oil retort in section; an

Figure 3 is a fragmentary view, in side elevation, of the device shown in Figure 2. Referring to the drawings wherein for the sake of illustration is shown the preferred embodiment of the invention the numeral 1 designates the base of the burner which is of elongated form being of oval or approximately elliptical shape. Preferably this base takes the form of a shallow pan or tray and is of metallic construction. Around the'upper edge of the base a marginal fiange 2 is formed .and serves to strengthen the base and provide a support for the shields as will hereinafter more fully appear. At

the air inlets into the air chamber.

the center of the base there is provided an integral and upstanding pedestal 3 which is of truste-conical form, the lower end of the pedestal 3 being open as clearly shown in Figure 1 and its upper end heilig closed by an integral apertured top plate 3a. Adjacent each end of the base 1 there is provided a seat 4 comprising an upstanding annular flange 4a and an annular ledge or shoulder 4l. around the lower end of said flange. In the space colnprehended by the shoulder 4b an opening is provided in the tray so that the seats 4 constituted by the flanges 4a and ledges 4b define openings in the base which constitute air inlets as will presently be understood.

An oil burner proper or jet is designated generally at 5 and is mounted on the pedestal 3; and overlying the oil burner 5 and extending from one seat: 4 to the other is an air duct or chamber 6. The air chamber 6' is in the form of an open ended tube curved to approximately U-shape and inverted in assembly with its open ends fitting in the flanges 4JL and resting on the ledges 4b of the seats 4. The open ends of the tube di# rectly connect with the` openings in the base.

which the seats surround and thus provide The air chamber orerlies the oil burner proper or 'jet and in the under wall of the air chamber immediately over the iet 5 is an outlet orifice or opening 6a which flares as shown in Figure 1 and is arranged to direct its heated stream of air immediately onto the jet in a flaring or substantially cone-shaped-stream.

The wall of the chamber 6 which overlies the Aoutlet 6a is depressed inwardly, as at 6" in order to provide deiecting surfaces for defiecting the air toward the outlet 6. The jet or oil burner proper 5 comprises a hollow cylindrical body closed at its ends and having a longitudinal slot 5a in its top. On the underside of the cylindrical body a relatively heavy nipple 5b -is formed and i-tis this nipple that rests directly on the top of the pedestal 3. The bore or opening of the nipple is alined with an aperture of the top plate and has threaded connection with a pipe 7 which extends through the aperture of the top plate 3. The pipe 7 includes lan upper section 7a and it is this section of the pipe 7 which has threaded connection with the burner 5 and the pipe 7 also includes a lower section 7b which is separated from the upper section by a wall or partition 8. In

of the pipe 7 by a conventional elbow or the like. The lower section 7b of the pipe 7 is connected by a pipe 12 and elbow 13 with one end of a retort 14 which is of U-shaped form and inverted in assembly, the retort 14 extending through the air chamber 6. The retort 14 is of much smaller diameter than the air chamber 6 but it is of similar shape, and in the assembly the axes of the retort and air chamber coincide. The opposite end of the retort 14 from that connected to the lower section 7" is connected to the upper section 7a by means of a pipe 15 and elbow 16. With this arrangement the wall or partition 8 in the pipe 7 completely isolates the ends of the retort and in this manner the oil is constrained to flow entirely through the retort in 4travelling from the pressure tank to the generator 5.

Around the flange 2 of the base a number of dowel ins 20 are arranged and are adapted to fit 1n suitable sockets provided therefor in the lower flanged ends of shields or hoods or casings which may be provided as found desirable for the protection of water backs, water fronts or water coils. The

shields or plates which are supported on the flange 2 of the dowel may come in sections and may completely enclose or partially enclose the various parts of the oil burner as found desirable.

In operation the supply of oil to the burner is regulated by the needle valve 10 which may be of standard cr conventional construction. The oil flowing through the pipe 9 and Athrough the lower section 7b of the stand pipe 7 passes into one leg of the retort 14 through the pipe 12. yThe oil then passes up through the retort where it is thoroughly heated, the burner proper or jet 5 having been started. The heated oil then flows through the pipe 15 and the upper section 7 of the stand pipe and thence into the body of the jet or burner proper 5 from whence it passes through Athe slot 5a. The oil being thoroughly and highly preheated readily vaporizes and mingles with the heated air which passes up through the legs of the air chamber or duct 6 and flows out through the flaring outlet 6 thereof. The air is also preheated during its travel through the air chamber and the air thus heated is directed onto the oil which issues from the slot 5a. The heated oil and heated air commingle and produce a combustible mixture of proper composition and properly conditioned for a suitable combustion so that the 'formation of carbon is prevented and the eflicient generation of heat is greatly enhanced. The course of the oil through the pipes and retort is indicated by single headed arrows and the course of the air is indicated by double headed arrows to clearly illustrate the mode of operation.

vI claim:

In an oil burner, a base, a jet mounted on the base and comprising an elongated hollow body having a single slot in its upper portion from which the oil issues in the form of a spray, means for supplying oil to the jet including a retort of inverted U-shaped form wherein the oil is preheated, said retort overlying the jet and communicating therewith, and means for supplying heated air to the jet and comprising an inverted -U-shaped air chamber mounted on the base and enclosing the retort and also overlying the jet, the air chamber being provided on its underside with a flaring outlet directly above the single slot of the jet, said air chamber having its portion above the flaring outlet inwardly deflected to provide surfaces or deflecting the heated air down through the outlet` and onto the slot of the et l OTIE'` CLARK KINSOLVING.
