Application filed September 2?, 1922. Serial. No. 590,826.

To all whom it may concern:

Be it known that I, WALTER S. HUM- IHREY, 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 Improvements in Oil Burners; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to oil burners and the primary object thereof is to provide an improved oil burner so constructed that the oil will be subjected to the action of an incandescent part of the burner as it is fed from the vaporizing chamber, thereby insuring a complete gasifying of the oil with. marked efiiciency over those types of burners in which the oil is ignited before it is generated into a relatively dry gas.

In carrying out my invention I provide a base for the burner consisting of a material having high heat resistance so that the base may be heated to practically incandescence, radiating intense rays of heat through the vapor discharged from the generating chamber prior to having the gas ignited.

It is an important feature of the invention that the base be of such material that it will heat up to incandescence since it has been found that the oil vapors burn with marked efficiency in an incandescent zone and it is also important that provision be made for eliminating or at least reducing the liability of carbon forming in the passages or in the vaporizing chamber because where there is an accumulation of carbon, the efliciency of the burner is materially reduced.

My invention contemplates the provision of means whereby disadvantages of present day burners are at least to a large extent overcome and whereby high efiiciency is procured.

In the drawings,

I Fig. 1 is a perspective view of the burner with part of the vaporizing chamber broken away.

Fig. 2 is a cross sectional view through the vaporizing chamber.

Fig. 3 is a cross sectional view through the burner complete, and

Fig. 4 is a plan view of the base with the removable cap piece detached. 1

Referring now to the drawings by numerals of reference:

1 designates a base of suitable material which possesses the ability to resist heat so that the temperature of the base can be raised to the temperature of incandescence. The base is provided with a recess 2, which is, in effect, a priming pan to receive oil. The center of the base is provided with an upstanding collar or wall 3, which surrounds a central air opening 4, the top of the collar supporting a cone-shaped cap piece 5, which has legs 6 provided with shoulders 7, which restupon the top of the'collar, as shown in. Fig. 3, so that the base of the cone 5 will be spaced from the top of the collar to permit air to pass up through the central opening 4 and over the base.

Surrounding the collar and spaced therefrom are vertical steps or supports 8, on which may rest the ring-shaped vaporizing chamber 9. The vaporizing chamber is an endless, circular tube and it rests upon the steps 8 of the base but it is fed with oil through a vertical pipe 10, which passes through the base and which has an outlet 11 discharging into the vaporizing chamber.

The vaporizing chamber is also connected to a bowed or semi-circular tubular member 12, so that the vapors generated in the ring may pass through the member 12 and out through an opening 13. spaced from but in line with the apexof the cone 5. The walls of the opening 13 are conical, the base of the cone being at the inner wall of the tube 12 and the apex near the outer wall so that liability of carbon forming will be reduced to a minimum.

The vaporizing ring and the arch-shaped member 1.2 will be made smooth on the in terior and will preferably consist of material which does not have an aflinity for carbon so that the carbon can flow along with the vapor and pass out through the opening 13. The advantage of having the inverted, conical-shaped opening 13 as the outlet orifice is that if the hole is drilled from the outside toward the center of the tube 12, there will be a burr on the inner wall which will tend to collect carbon and cause the opening 13 to be closed. I prefer to drill the hole in the form shown in Fig. 2 so that there will be no obstruction of the carbon carried along with the vapor. The hole 13 can b'e-made'by drilling through "at 13' and then drilling the hole 13 and subsequently closing the opening 13'. Therefore, there will be an unobstructed passageway for the vapors and liability of carbon accumulating Within the vaporizing chamber will "be reduced to a minimum.

\Vhen the incoming oil reaches the rin fi, it may be vaporized and pass into the member'12 and then onto the cone 5. Previously, the cone will have'been heated to a very'high degree by priming; that is, a quantity of oil, alcohol or the like, will be placed in the pan or 'recessjQ and ignited so that the base will be relatively hot.

Asthe vapojrstrikes the incandescent cone andmixes with the air passing through the opening 4, it will burn with a high degree oi: -efiic'1ency wltho'ut any smoke or soot and combustion will be further supported by air furnished -through the vertical ports 14.

*The flame Will "pass downwardly over the ,cr1e, un'der the ring-shaped vaporizing chamber and laterally past the base. l.

'lherefore' a ring-shaped flame ,will be and after the burneris started, allot the parts of the burner will .be relatively hot: the base particularly, being constructed of suitable material which .will become incandescent under moderate ;heat. for example, tire tiling, will behot enough to, in effect,

It will be apparent, of course, that when the vapor strikes the top of the cone, it will be spread in all directionsso that a substanitially horizontal sheet of flame will be 'provideld With very great intensity due to the manner of generating the gas and the mannert of feedingthe air to support combustion andtto the fact that incandescent surfaces ,are constantly present,
