UNITED STATES PATENT ALBERT EDWARD EAG-ER, O F PHILADELPHIA, PENNSYLVANIA.

BURNER.

To all 'whom t may concern:

Be it known that I, ALBERT E. EAGER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Burners, of which the following is a specification.

One object of my invention is to provide a burner construction which will efiiciently burn liquid fuel, such for example as `light distillate oils, with a blue fiame which will not form a carbon deposit on devices which are heated thereby. Thus my improved burner construction `is particularly adapted for use in stoves, furnaces or other heating devices.

Another object is to so construct my invention that it can be quickly and easily made and assembled and willbe of durable construction.

A still further object is to so construct my improved burner that it can be quickly started in. operation and will be economical and safe while in use.,

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a front elevation of my improved burner construction,

Fig. 2 is a top plan view of F ig. 1,

Fig.V 8 isa sectional plan view taken on the lineB-S yof Fig. 1, and

Fig. 4 is a sectional elevation taken on the line 4 4 ofFig. 2.

Referring to the drawings, 5 represents an elongated base plate having a peripheral flange 6. This base plate has two hollow domes 7 and 8 made Aintegral therewith. These domes respectively include depending cups 9 and 10, said cups being open at their tops and being provided with perforations 11 atrtheir bottoms. The cups 9 and 10 are of smaller diameter than the internal diameter of the domes 7 and 8 and thereby provide spaces 12 and 13 respectively between the cups and the adjacent inner surfaces of the sides of the domes.` The tops of the domes 7 and 8 are closed with the exception of slots 14and 15 which lead from Vthe up- Specication of Letters Patent.

Application led November 6, 1918. Serial No. 261,328.

per portions of the spaces 12 and 13 into the cups 9 and 10 above jet pipes 16 and 17.

bottoms of the cups 9 and 10 have air intake ports 20.

The jet pipes 16 and 17 are respectively connected by supply pipes 21 and 22 to opposite ends of a chamber 23 provided by an elongated hollow flame-distributing and fuel-vaporizin casing 24. This casing 24 extends entire y over both of the domes 7 and 8 and is supported above said domes by the supply pipes 21 and 22.

The bottom of the casing 24 is recessed as shown at 25, said recess being of greatest depth adjacent its Vmiddle and gradually becoming shallower at its edges, as clearly shown in Fig. 4. Furthermore, this bottom of the casing 24 terminates in a peripheral flange 26. The top of the casing 24 `is provided with a central tapped opening 27 into which is screwed the lower `end of a back pressure or equalizing reservoir 28. This reservoir is substantially spherical in shape as shown in the several views of drawing and has a contracted portion or neck 29 which forms the joining portion of the reservoir with the casing as `above described.

The liquid fuel is supplied to the reservoir 28 by means of a pipe 30 which enters said reservoir at a position a considerable distance below the top of the reservoir and slightly above the neck 29. By this arrangement the reservoir provides an equalizing chamber which after the burner has started to heat causes a slight gas generation in the reservoir to start the vaporization of the liquid fuel.

The casing 24 is of greater length than the distance between the outer portions of the domes 7 and 8 and thereby serves to distribute the flame of the burner entirely around the peripheral flanged edge 26 of the casing 24 to give an even distribution of heat, as wlll hereinafter be more fully described.

Also, the top of each of the domes 7 and 8 has a bead 31 which provides a slight flare of the flame.

The space of cach of the cups 9 and 10 below the jet pipes is preferably filled with a material such as asbestos and to start the burner this material is saturated with fuel and ignited; the interior of the cups 9 and 10 being of greater diameter than the external diameter of the jet pipes and space is provided at each side of the jet pipes to permit the flame from the material 32 to pass upwardly heating the jet pipes and also heating the casing 24 and reservoir 28. This initial heat causes the liquid fuel to be vaporized sufficiently to produce enough vapor to start the burner after which the burner will continue to operate and as the heat increases the vaporization of the liquid fuel will be accelerated until the burner is operating at its fullest capacity.

The particular construction of my improved burner produces an improved result. By having the jet holes 1S and 19 open into the combustion chambers 33 of the cups 9 and 10 below the tops of said cups and also below the slots ll and 15 a substantially perfect combustion of the vapor with the air entering the combustion chambers through the slots 14 and 15 is attained. Further than this by having the slots 14: and 15 enter the combustion chambers in the position above noted the air is initially heated and there is a direct upward pressure of the air to the top of the domes 7 and 8 through the spaces 12 and 13 which produces a direct draft to forcibly enter the heated air into the combustion chambers at positions intersecting the jets of fuel vapor as they pass upwardly out of the holes 18 and 19.

By having the reservoir 28 entering the casing 24 centrally and the supply pipes leading off from the opposite ends of the casing both of the jet pipes receive substantially the sam@ amount of fuel under the same pressure and an equal flame is produced. The fiame after leaving the combustion chambers 33 impacts with the recessed surface 25 of the casing 24; and distributes itself thereover and passes around the peripheral fiange 26 and thence upwardly. This action causes the heating of the casing 2&1- to a high degree and thereby quickly vaporizes the fuel and provides a back pressure in the reservoir 28. Air also enters the cups 9 and 10 through the perforationsv 11 and passes upwardly and mixes with the vapor and air from the slots 14 and 15.

The feed operates by gravity and is accelerated duc to the pressure set up as above described. A practically perfect combustion is secured and the flame produced is extremely hot.

The sup-ply pipe 21 is preferably provided with a T-fitting 34C which is normally closed by a plug 35 and the fitting 34; is in alinement with the chamber 23.

The parts of my invention can be quickly assembled and can be readily cleaned internally and externally.

lfVhile I have described my invention as taking a particular form7 it will be initierstood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
