I '0 all whom it may concern:

Be it known that we, Roy S. NnLsoN and VVINFIELD S. NnLsoN, citizens of the United States, residing at Oklahoma, in the county of Oklahoma and State of Oklahoma, have invented certain new and useful Improvements in Oil-Burners; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in oil burners.

The object of the present invention is to improve the construction of oil burners and to provide a simple, practical and comparatively inexpensive oil burner designed for use in stoves, furnaces and various other heating devices and adapted for burning coal oil and other hydrocarbon.

i/Vith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings Figure 1 is a side elevation of an oil burner constructed in accordance with this invention, Fig. 2 is a central vertical sectional View of the same. Fig. 3 is a similar view taken at right angles to Fig. 2, Fig. 1 is a horizontal sectional view on the line l4c of Fig. 3, Fig. 5 is a. side elevation of the upper section of the burner proper. Fig. 6 is a reverse plan view of the base, Fig. 7 is a detail view of the'retort.

Like numerals of reference designate corresponding parts in the several figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the oil burner comprises in its construction, a retort and a burner proper having a base 1 of substantially cylindrical form provided at the bottom With supporting legs or lugs 2 and having an inper section is provided at the juncture of the two portions with a shoulder 8 adapted to rest upon the upper edge of the base.

The upper section of the burner proper is also provided below the horizontal shoulder 8 with an annular face 9 arranged vertically and fitting the interior of the base at the top thereof as clearly shown in Fig. 2 of the drawings. By this construction a tight connection is made between the upper section and the base at the top and bottom of the latter. The upper. section is also provided at the bottom of its lower or inner portion with an exterior annular recess 10 which forms a shoulder and which fits within the annular flange 3 of the base. The annular flange 3 extends from the vertical walls ofthe base to the bottom of the up per section and the tapering of the latter forms 'an intervening space 11 between it and the base. The flange 3 is provided with air inlet openings 12 which are located at the bottom of the intervening annular space 11 and the lower tapered portion of the inner section is provided with inclined perforations 13 arranged at intervals and adapted to permit the air to pass from the intervening space to the interior of the up per section.

The upper cylindrical portion of the upper section is located in substantially the vertical plane of the walls of the base and it is provided at opposite sides with recesses 14 in which are arranged the terminal portions 15 and 16 of a transversely disposed pipe 17 which has a depressed intermediate portion formed by downwardly extending bends 18. The end 15 of the transverse pipe 17 has an imperforate end wall or closure 19 of any desired construction. The other end 16 is connected by a vertical pipe or branch portion 20 with a top transversely disposed generating pipe 21 located above and in spaced-relation with the lower transverse pipe 17 connected with the vertical portion 22 of the supply pipe. The lower transverse pipe is preferably rectangular or oblong in cross section while, the top transverse pipe is preferably circular in cross section and the latter is equipped with a retort-23 which is located directly above a nipple 2% extending upwardly from the center of the depressed portion of the lower transverse pipe 17.

The retort is preferably in the form of a cylindrical. casing provided at opposite sides with openings 25 to receive the top transverse pipe 2lwhich is composed of two sections spaced apart to receive the casing'between them. The cylindrical casing which has a top plate 28- is provided with a series of spaced baffle plates 26 adapted to cause the liquid or gaseous fuel to travel back and forth across the cylindrical casing of the retort before passing to the nipple 24:. The top plate 23 is secured by screws or other suitable fastening devices to the body portion of the cylindrical casing. The lower portion of the upper section of the burner proper constitutes a starting cup and a quantity of liquid hydrocarbon is placed in the lower imperforate portion of the upper section and is ignited causing the flame to impinge against the bottom pipe and also the top transverse pipe and heating the top-and bottom pipes sufliciently to generate gas from oil fed to the pipes. The oil in passing through the upper generating. pipe is converted into a gas and the gas ,passes downwardly through the connecting pipe 20 and is discharged through the nipple where it burns beneath the retort.

The oil burners may be constructed of any suitable material and of any desired size to adapt them for the particular heating apparatus in which they are to be used and it will be clear that owing to the relatively small bore of the nipple that the. gas gen erated in the pipes will be discharged under pressure and a constant supply of gas maintained. The lugs or legs 2 support the air inlet openings 12 above the grate or other supporting surface upon which the oil burner is placed and a proper supply of air to the interior or chamber of the inner casing or section d is maintained both in the initial starting of the heater and in the operation of the same after the generation of gas in the pipe is complete. While it is preferable to use coal oil as a fuel a heavier oil may of course be employed.

Vhat we claim is 1. A burner of the class described including a burner proper composed of a base, and

bottom thereof and spaced therefrom between the top and bottom of the said base to form an intervening space, said base being provided at the bottom of the intervening space with an air inlet and the said upper section having an air outlet communicating with the said base, said upper section being closed at the bottom to form a starting cup, and a pipeextending across the upper section and provided at an intermediate point with a discharge aperture.

2. An oil burner of the class describedineluding a substantially cylindrical base provided at the bottom with an inwardly extending flange having apertures and an upper section of substantially cylindrical form fitting within the base and the flange and forming an intervening air space, said upper section being closed at the bottom to form a starting cup and provided with perforations located at the upper portion of the said intervening space, and a transverse pipe supported by the upper section and provided with a discharge nipple.

3. An oil burner of the class described including a burner proper comprising a base consisting of a casing and provided at the bottom with an inwardly extending flange having an air inlet, an upper section consisting of an upper portion and a lower reduced portion fitting within the outer section or base and forming an intervening air space,

said lower portion being also provided with an air passage communicating with the said intervening space, and a pipe extending across the upper section and provided with an aperture for the escape of gas.

4. An oil burner of the class described including a burner proper comprising a base of substantially cylindrical form provided at the bottom with an inwardly extending flange having an air inlet, an upper section consisting of an upper substantially cylindrical portion and a lower reduced portion fitting the base and the flange thereof and forming an intervening air space and having a closed bottom to form a starting cup, said upper section being also provided with apertures communicating with the said intervening space, a lower transverse pipe extending across the upper portion of the upper seetionan'd having an aperture for the discharge of gas, a top generating pipe located above the lower transverse pipe, and means for connecting the said pipes.
