BURNER.

Application filed January 9, 1922. Serial No. 527,961.

To all whom it may concern:

Be it known that I, FRANK Mi DALLEN, a'c tizenofthe United States, and a residentof Chicago, in the county of- Cool: and

State ofIllinois, have invented a new and useful Improvement in Burners, of which the following is a full, clear, and exactdescription. My invention relates to improvem'entsin burners; and more particularly try that type of burner'which utilizes a fluid as a fuel, and it consists in the combinations, constructions, and" arrangements herein described and claimed...

An object of my invention isto provide a deviceof the character described which has meansfor providing a steady feed-of fuel to the'combustion chamber. fA furtherobject of my invention is to provide a'deviee of'the character described whichis adapted to change a liquid fuel into a combustible gas before the latter is burned.

"A further object of my 'invention is to provide a device of the character described which has a novel vaporizing chamber.

A further object of my invention isto pro? vide a devicepf the character described in which jliqui'd fuel isfirst vaporized and is then' mixed with the desired quantity of air before .itis conveyed .jto the combustion A fur ther object offlmy inv'e ntion isto provide a device ofthe character described which is simple in" constriictionlefficient for the purpose intendedfand which is not like- 1y to easily get out of order.- 'Oth'er objects and advantages will appear in'the following specification, andthe novel features or the invention will be particularly pointed out in the appended claims. My invention is illustrated inthe accompanying drawings, forming part of this application, in which F "Figure l is'a vertical section through the device parts thereof being shown in.ele-.

vation',

Figure? is a vertical section through another portion of-the device, parts thereof being shownin elevation, and y I :Figure 3 is a section along the line 3-3 of Figure 2. I I

Incarrying out my invention, I provide a body portion 1 which has an annular va Afuel feed p1pe3 communicates with a groove 4 in the body ortionl, the groove in turn comend of the chamber 2.

municating with the bottom of the chamber body l fills a portion of the chamber 2.

cept fora small portion 5 of the which Tn other words, the chamber 2 resembles a split ring. As shown in Figure 3. the pipe the groove 4- are disposed adjacent to one end oi the chamber 2. An. outlet pipe 6 communicates with groove 7-which in turn is in communication with the other It will be observed however, that the groove 7 communicates with the chamber 2 adjacent to the top there of and that the groove 4 communicates with the chamber 2 adjacent to the bottom thereof. The pipe 6 supports a sleeve 8 which has secured thereto, an L-shaped pipe 9. The tree of the pipe 9 is provided with a reservoir 10 and a smallorifice 11. The pipe 3 carries an elbow 12 which has a sleeve 13 disposed thereabove. The sleeves 8' and 13 are-adapted to secure ;1 pan-shaped member 1 1 to the body portion 1. The bot y portion 1 has a downwardly projecting annular flange 15 which is adapted to bereceived in a recess 16 of the member I l. The flange 15 has a plurality of openings 17 for a purpose hereafter described I "As clearlyshown in Figures 1 and 2, the central portion of the body l has a gas chamber 18 in'the top thereof, the upper end of the chamber 18 having radially extending openings 19' for a. purpose hereafter d.e scribed. The inner wall of the chamber 18 tapers outwardly. A pipe 20 is frictionally carried by the member 14 and has one end disposed adjacent. to the chamber 18 and the other end disposed above the orifice 11.

From the toregoinrq description of the va rious parts of thedevice. the operation thereof may be readily understood. A valve 21 is connected to the pipe 3 by means of a pipe 22, and. when opened. admits fuel from a source (not shown) into the chamber 2. When lighting the burner. the valve 21 is first opened so as to admit a very small quantity of the liquid fuel to flow into the chamber 2. The valve 21 is then closed. and the flame of a blow torch (not shown) is brought into contact with the walls of the chamber 2. This heats the walls of the chamber and changes the liquid in the chamber into a vapor gas which will beforced downwardly through the pi 'aes 6 and 9. and into the reservoir 10. The vapor 'ga's being combustible. The vapor gas in passing from the Orifice 11 into the pipe 20, becomes mixed with the air which passes upwardly in the pipe 20 with the vapor gas. It is to be noted that the vaporgas does not merely mix with the air as it flows upwardly in the pipe 20, but mixes with the latter in the right proportion. This gas passes into the chamber 18 and then downwardly from the chamber 18 into the compartment and out through the openings 17. The gas will also flow outwardly through the openings 19. As heretofore stated, the interior wall of the chamber 18 is tapered so as to deflect the gas downwardly into the chamber 23. This con struction prevents any back pressure in the pipe 20 due to the gas striking the top of the chamber '18 and rebounding back into the pipe 20. The gas will flow from the pipe 20 into the chamber 18, will strike the top wall of the chamber 18, and will then be forced downwardly along the tapered sides of the chamber and into the compartment 23. As soon as the gas flows out through the openings 17, it is ignited by the blow torch and will continue to burn as long as gas is generated. As soon as the gas flows out through the opening 17, the valve 21 may be opened so as to admit more fluid into the chamber 2 which in turn will be changed into a vapor gas. The flames from the openings 17 and 18 will heat the walls of the chamber 2-, whereby the fluid in the chamber will be readily turned into a vapor gas. The

blow torch may then be dispensed with, and V the burner will continue to function. as long as the valve 21 is opened.-

As heretofore stated, the device is simple in construction and is e-tiicientfor the purposeintended. It affords a positive means for changing all of the liquid fuel, first into a vapor gas, and then into a combustible gas, before it is burned. It will also be observed that'by merely moving the pipe 20 with respect to the member 14, it will change the quantity of air admitted into the chamber .18 and will therefore change the length of the burning flame. By positioning the outlet groove 7 above the inlet groove 4, 1 pro.- vide a simple means by which the fluid has to be changed into a vapor gas before it is permitted to enter the outlet pipes 6 and 9. Any excess liquid in the chamber 2 will drain back into the groove 51.

I also provide a means by which the quantity of vapor which is emitted from the orifice 11 may be varied at will. This means comprises a screw 2 1 which is mounted in the free end ofthe pipe 9. It will be ob served that the screw 24 has a conical-shaped izing chamber, said chamber having a recess at each end thereof, one of said recesses being disposed above the plane of the other recess, an inlet pipe communicating with the lowerrecess, and an outlet pipe commu nicatingwith the upper recess.

2. A burner comprising an arcuateshaped vaporizing chamber, said chamber having a recess at each end cesses being disposed above the plane of the other recess, an inlet pipe communicating with the lower recess, an outlet pipe communicating with the upper recess, a second chamber disposed below said vaporizing chamber, and a vertical pipe communicating with said second named chamber, said outlet pipe terminating adjacent to the lower end of said vertical pipe, said second named chamber having outlet openings in the wall thereof. r

3. A burner comprising an arcuate-shaped vaporizing chamber, said chamber having a recess at each end thereof, one of said're' cusse being disposed above the plane of the other recess, an-inlet pipe communicating with the lower recess, an outlet pipe communicating with the upper recess, a second chamber disposed adjacent to said vaporizing chamber, and a vertical pipe communicating with said second named chamber, said outlet pipe having a small orifice in its free end, the axis of the orifice being alined with the axis of said vertical pipe, said orifice beingspaced below the lowerend of said vertical pipe, said second named chamber having outlet openings in the walls thereof, the openinges being disposed above and below said vaporizing chamber.

1. A burner ofthe character described comprising a body portion having an arcuate vaporizing chamber, a gas chamber, said gas chamber being formedwith a substantially conical-shaped recess in the upper wall thereof, a vertical pipe communicating with the gas chamber arranged for longitudinal movement, and an outlet pipe leading from said vaporizing chamber and terminating below the lower end of said vertical pipe, said gas chamber being formed with an ironate depression on the outer upper wall there of concentric the conical-shaped recess on the inner side thereof, and being provided with perforations through thewall-of said gas chamber so that gases from the chamber may pass through thewall thereof into the arcuate recess.
