OIL BURNER. v

Application led April 15, 1922. Serial No. 553,210.

To all whom it may concern:

Be it known that I, JAMES K. BEAUCHAMP, a citizen of the United States,` residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Imp'rovementsin Oil Burners, of which the following is a specification.

My invention relates to oil burners and refers more particularly to that type of burner employed in stoves or furnaces for utilizing oil as a fuel instead of coal.

One object of the invention is the pro-` vision of an oil burner which can be readily installed in the fire box of a stove or the fire pot of a furnace and which will use oil as a fuel supplied thereto by the force of gravity; one which is economical in the con sumption of oil, and one which'will prevent the accumulation of carbon and give the highest degree of heat under all conditions.

A further object is to provide a self-generating burner for effecting a rapid an complete conversion of the fuel oil into hot vapors, and to provide means for thoroughly mixing air with such vapors for the purpose of producing a'highly inflammable mixture.

Anothervobject is the provision of an oil burner which can be produced at relatively small cost, which is not likely to get out of order, one in which access can be readily gained to all parts for the purpose of clean-l ing and making repairs, and one which will be thoroughly efficient-and pract1cal in operation.

In order that the invention may be fully understood, reference will now'be had to the accompanying drawing, in which:

F ig. 1 is a broken plan view of the burner.

F-ig. -2 is a vertical central section on line II-II of Fig. 1.

In carrying out the invention,` I employ a bowl-shaped combustion chamber 2 comprising a bottom 4 and a marginal `flange 6 extending upwardly from said bottom 4.

8 designates 'a generator consisting of a chamber 9 formed integral or otherwise associated with the central portion of the con bustion chamber 2, and a removable cap 10 adapted toerest upon the bottom 4 of the combustion chamber' 2 where it is held 1n place by the upper margin of the chamber 9, as disclosed by Fig. 2. The cap 10 is provided near its upper portion with perforations 12 and atits upperV end with a perforated plate 14 surmounted by aremovable saucer-shaped oil distributor 16 threaded ably,

upon the upper end of an oil inlet pipe 20 extending centrally through the generator 8 and communicating at its lower end with an oil supply pipe 22. The oil supply pipe 22, 30 preferably leads from a tank not shown, from which the oil flows by gravity to the generator 8. Said supply pipe 22 is,'prefer larger in diameter than the inlet pipe 20, sothat when oil drains therefrom it will. flow back into the supply pipe 22 instead of leaking from the bottom of the generator 8. The lower portion of the generator 8 is surrounded by a flange 24 extending upwardly from the bottom 4 of the combus- 70 .tion chamber 2, to form in conjunction with said bottom 4, a shallow basin for catching any overflow from the generator 8. The overflow is conducted from said basin by a. drain pipe 26 which may lead to any suit- 75 able point.

Air is admitted centrally over the gend erator 8 through a relatively large intake tube 28 arranged in the form of a gooseneck. The lower leg 30 of the air intake 80 pipe 28, is preferably, cast integral with the combustion chamber 2, while the upper leg 32 is connected to the upper end of the lower leg 30 by a hinge 34, so that said upper leg 32 may be swung backwardly to give free 85 access to the combustion chamber 2 and the generator 8 for the purpose of cleaning the same or making repairs. When the leg 32 is in its normal positlon, Fig. 2, its weight and the flange `35 surrounding the joint 33 be'- 90 .tween the legs 30 and'32, tightly close said joint 33 so that air cannot enter therein and. interfere with the draft through the intake pipe 28.

The generator chamb'er9, in practice is, 95 preferably, filled with powdered lire clay and asbestos forming a wick, which on becoming saturated with oil causes the same to readily ignite.

In the operation of the burner, oil is admitted to the distributor 16 from whence it spreads over the perforated plate 14, a portion entering the generator chamber 9 and saturating the powdered re clay and asbestos. The oil is then ignited and as it becomes heated the oil is formed into vapor which escapes through the perforations 12 and 14 and in ascending becomes mixed with the inrush of cold air through the tube 28.

As the air and vapor b ecome thoroughly intermingled, ahighly inflammable mixture is produced which readily ignites and produces a flame that fills the combustion chamber 2 and impinges against the air intake 28 thereby heating the same. The flame maintains the generator 8 at a high enough temperatureto continue the vaporizing process as long as oil is admitted to the burner. It also enables the supply of oil to the generator to be reduced in moderatevweather and thus effect a saving of fuel without danger of the fire becoming extinguished.

From the foregoing description it will be readily understood that I have produced a burner embodying the advantages above pointed out, and while-.I have shown and described the preferred construction, `combination, and arrangement of parts, I reserve the right to make such changes as properly fall within the spirit and scope of the claims.

Having thus described my invention,` what I claim and desire to secure by Letters Pat-- ent, is: i

1. An oil burner consisting of a combustion chamber, a generator chamber formed integral with the bottom of said combustion chamber, a perforated cap forming the upper portion of said generator chamber, means for supplying the combustion chamber with oil, and an air intake tube terminating above said generator chamber',

2. An oil burner consisting of a combustion chamber, a generator within said combustion chamber, an oil supply pipe extending upwardly through said generator, an oil distributor surrounding the upper portion of said supply pipe and resting upon the' top of the generator, and an air intake tube associated with the combustion ch'amber and having its discharge end .inverted just above said generator. i

3.4 An oil burner consisting vot a combustion chamber, a generator within said combustion chamber, andv a goose-neck air intake pipe consisting of a lower leg extending upwardly from the bottom of the combustion chamber and an upper leg hinged to said lower leg to swing upwardly and backwardly and having aninverted discharge end terminating over the generator.

In testimony whereof I affix my signature, in the presence of two witnesses.
