AIR-BLAST BURNER.

Application filed January 6, 1923. Serial No. 611,048.

My invention relates to an improvement in air blast burners. A

In.this particular invention, I have succeeded in producing perfect combustion a with a wide range of flame adjustment, the

flame being white instead of red and smoky as is the case with other burners of this type. Furthermore, I get a uniform and unvarying pressure of oil against the valve. II

new burner are an improved burner bowl, in connection with a multiple jet gas .generator in the center thereof, together-with the central air nozzle. r

In the accompanying drawings:-

Fig. 1 is a view in elevation, and partly in section; Y

Fig. 2 is a perspective view' of the air nozzle; v v N Fig. 3 is an enlarged section through 'the gas generator;

Fig. 4'is a plan view of the valve dial and pointer. A, represents an air nozzle which includes a spider 1, cast from metal, and a down draft air pipe 2,-the lower end ofwhich is held frictionally in the central body portion of the spider. k

The numeral 3 represents the burner bowl 39 upon the upper edge of which the spider l rests. K The burner bowl is in the form of a cylinder, with an upturned edge'4,-and having .a bottom 5 which slopes toward the center and up to the generator.

Ordinarily, the bottom ofthe burner bdwl' of this type slopes away. from the center and the object seems to be to-vaporize the I 'oil as it flows down the slope, and then burn 40 it about midway between the center and the edge of thebowl; but. in this way. thev enerator does not convert the oil into gas efore it is deliveredto .the bowl. After the oil in a my burner becomes generated, no raw oil, or even oil vapor, is to be seen. The oil is converted into a" dry gas which passes throu h the small holes 6 .of the generator 7, an the incoming air through t A from the 150 row in Fig. 1 discharges so as to rive this gas directly down to the bottom of the burner bowl. At this point ignition takes place, and, by the time this gas reaches the- The principal features included in this e nozzleipe 2 (as indicated the ar-.

The down-draft pipe 2 is preferably made ofheavy sheet steel, and this pipe must be enough larger in diameter than the opening 8 in the bottom of the air nozzle A to prevent friction or resistance to the air passing down through the pipe or tube 2.

While this pipe or tube is illustrated as passing straight down through the top of the stove into the burner, its construction and position can be modified to meet the 66 requirements of stoves or furnaces where an opening throughthe top cannot be ar-' ranged. For instance, this tube can be provided with an elbow, so it will pass through the front,door ofa furnace or stove. The 7 door openin would have to be closed, of course, 50 t at all air must pass down through the pipe or tube 2.

Referring to the generator, the lower end of the draft nozzle must be placed the proper distance from the bottom of the burner below, and the generator must enter the lower end of the draft nozzle, so the small jets are about one-fourth inch above thebottom of the nozzle.

The generator is vertically adjustable for this purpose through the screw-threads 9' and 10. vWhen thus adjusted, the incoming air carries the gas down with it, and forces 11, on which is fastened a dial 12 and point-- I er 13, so that the .proper position of the valve can always be determined. 1

'The action of his burner is the same when placedin a coal-burning stove as when placed in an oil-stove. A uniform and un- 96 varying pressure of oil against the valve is necessary,-and this may be provided in various ways, as forv instance by means of a float (not shown) in' the tank as fully set forth in patents already granted to me and 100 applications still pending.

- I claim 1. An air blastburner incl-uding a burner bowl having a substantially concave bottom with the center portion thereof sloping upward toward the center, a generator mounted upon said center port on at the top of the upwardl sloping sides, the sides of said generator ing in alignment with and terminating in the sides o and gener- 0.

ator, and an air'pipe extending downward over the generator and having the discharge end thereof terminating below and in close proximity to the discharge point of said enerator, the sides of said air pipe slopmg toward the discharge point of said generator.

2. An air blast burner including a burner bowl, a generator mounted substantially at the center thereof, and having a discharge point adjacent the top, said burner bowl having a substantially concave bottom with ator, an air supply pipe extending downward toward said generator, and an air nozzle supported upon said burnerbowl and receiving the lower end of said air pipe. said nozzle having thelower discharge end thereof terminating below and in close proximity to the discharge point of said generator, and being tapered toward the generator for discharging the air tOWEL ld the discharge point thereof at the centerof the burner bowl.

In testimony whereof ture, r HENRY M.
