AXEL VJ'RNER, OF GHCAGO, ILLINOIS.

BUR-NER.

Application led November 2, 1923.

.T0 all whom t may concern:

Be it known that l, AXEL llllnnnnn, a citi Zen of the Unit-ed States, and a resident of Chicago, @ook County, and State of lllinois:` have invented certain new and useful linprovenients in Burners, of which the following is declared to be a full, clear, and exact description.

This invention relates to burners, and in its present forni has been designed for use as a kerosene burner. yl'he principal object of this invention is to `provide a burner of improved construction., capable of produicW ing an intensely hot, blue flame, andvat the saine tinie eliminating the usual noise or roaring sound that accompanies the burning of kerosene in a hydrocarbon burner.

lVith these and other objects in view, this invention consists in the several novel features hereinafter described and claimed.

rllhe invention is clearly illustrated in the accompanying drawing, in which Fig. 1 is a central, vertical section. through a burner embodying a sirnple forni of the present invention; Fig. 2 is a plan thereof; Fig, 3 is view looking at the bottoni of a spreader plate forming part of the burner, and Fig. 4 is side elevation of said plate.

Referring to said drawing, which illustrates one embodiment of the invention, the reference character 5, designates a burner tube arranged to be connected to a fuel supply pipe (i, as for instance by a pipe coupling 7. rlhe pipe G leads from a fuel tank (not shown) in which is contained kerosene or other hydro-carbon liquid fuel, under pressure, as is well understood.

-The burner tube has a. relatively thin cylindrical shell or wall 8, which is shouldered near its upper end, as at 9 and tapers upwardly as shown at 10. The end wall 11 of the` burner tube is relatively thick as coin-- pared with the s iell portion 8 and contains a central discharge duct 11a of exceedingly srnall diaineter, preferably formed by boring a hole with a line drill, [its illustra-tive ofthe size of the orifice, one having a diameter of twelve-thousandths of an inch, has been found to operate successfully. A wire gauge filter 30, is preferably contained in the hollow of the burner tube to filter out any solid or foreign rnatter from the kerosene Secured upon the upper end of the burner tube, and spaced therefrom, is a burner pan 12, which is formed with bottoni 13 having an upturned marginal flange 144 The upf Serial No. 672,255.

per face 13n4 of the bottom 13 is ilat and sinooth, and a central opening 15 is formed in said bot-tom through which the generated passes, The pan 12 is forined with two Y wnwardly converging arnis 16, which join with a ring or band 1'? that slips upon the tapered upper end 1() of the burner tube and connects the burner pan with it. Air passages (one of which is shown at 18) are located between the arms 16, and adniit oxygen through the opening 15, to the space directly above the burner pan.

Resting on the face 13et of the burner pan bottoni is a. spreader plate 19, whichl is of less diameter than the internal diameter of the flange 14, to leave an annular space 2O therebetween, and said spreader plate is formed with lugs 21 arranged circumferentially along the lower face thereof, and spaced apart to leave notches or ypassages 22 therebetween for the escape of the burn ing vapor. The lower face 23 of the spreader pan is flat and parallel with the upper face 13ZL of the bottoni 18 of the spreader pan. l have found from actual experiments that the proper height of the notches or passages 22 is about live sixty-fourths of an inch, to bring `about the best results, because if the notches are higher, a roaring sound is produced, and if the notches are lower a clicking action results. In order to centralise the spreader plate and space it from the annular flange 14C, three or more lugs are extended beyond the plate to the flange, as at 24. To prevent warping of the plate, l prefer to forni radially eX- tending ribs 25 on its upper side that eX* tend from a central boss 26 to an annular rib 27, formed on the upper side and at the margin of the spreader plate.

ln accordance with the usual practice, a priming cup (not shown) is employed for receiving alcohol or other volatile fluid which is ignited to pre-heat the parts and gasify the kerosene or other liquid fuel in the top of the burner tube. The fuel (under pressure) is then turned on and the gasified fuel discharged through the duct 11?L in a fine jet or streain against the bottom of the spreader pan where it is spread outwards evenly in all radial directions, pass ing through the notches 22 and being deflected upward by the annular flange 14. The gaseous fuel is ignited and burns with a blue, intensely hot flame, without producing any appreciable noise or roaring sound,

The heat generated in thevburner pan is Conducted to the burner tube by the arms 16, and gasifies the liquid fuel in the upper end thereof.

From my experiments I found it necessary, in order to obtain the best results, `-to provide al relatively long, discharge duct in the burner tube of exceedingly ksmall diameter, practically a capillary duct, and located in position so as to 'direct the fine jet or stream at the center of t-he spreader plate, in order that the fuel may be spread evenly in all radial directions from the cen ter of the plate. I also find that unless the height of the notches or passages is liniited closely to five sixtyi fourths of an inch, a roaring sound will be ,produced if the notches are appreciably higher, and a choking action 'will result if'4 they aremade lower. I `also find that it is Vessential that the adjacent faces of the spreader plate and burner pan be made flat and parallel.

The burner is capable of use in stoves, heaters, furnaces, and in fact in many other devices where an intensely hot flame is desired. l/V ith this burner the fuel is economiZed and ordinary commercial kerosene may be used effectively as the fuel.

More or less yvariation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of 4the construction shown and described, but intend, in the following claims to point out all ofthe invention disclosed herein.

I 'claim as new, and desire to secure by Letters Patent:

l. A burner comprising, in combination, a burner tube having a thin side wall and a relatively thick top wall, the top wall be ing formed with a centrally' disposed, relatively long, capillary discharge duct, a centrally apertured burner pan secured upon said burner tube, and having an upturned marginal flange, the upper face of said burner pan being flat, and a spreader plate above and spaced relatively close to said burner pan, the spreader plate being of less diam eter than the internal diameter of said flange, and its lower face being flat and parallel With the upper llat face of the burner pan, the flat upper face of the burner pan and lower flat face of the spreader plate forming therebetween a relatively thin hori- '/,ontal passage of uniform thickness throughout and the space between the edge of the spreader' plate and flange of the burner pan being relatively wideI as compared with the thickness of said flat passage.

2. A burner comprising, in combination, a burner tube having a thin side wall and a relatively thick top wall. the top wall be ing formed with a centrally disposed, rela* tively long, capillary discharge duct. a ceutrally apertured burner pan secured upon said burner tube` and haring an upturned marginal flange, the upper face oi' said burner pan beingl flat, and a spreader plate above said burner pan, and of less diameter than the internal dian'reter of said flange, said spreader plate being formed with a row ol' spaced lugs on its lower face, arranged ein eumferentially about the same, and resting on the bottom of said spreader pan, the N spaces between said lugs being relatively low, the Hat upper face of the burner pan and lower flat face of the spreader plate forming therebetween a relatively thin horizontal passage of uniform thickness thrmlglr out and the space between the edge ol the spreader plate and flange of the burner pan being relatively wide as compared with the thickness of said flat passage.
