BURNER FOR HEATING-STOVES.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed March 30, 1920. Serial No. 369,877.

To all whom it may concern:

Be it known that I, OLIVER J. RossnLor, a citizen of the U nitedStates, residing at Kokomo, in the county of Howard and State of Indiana, have invented certain new and useful Improvements in Burners for Heating- Stoves, of which the following is a specification. I v r This invention relates to an oil or gas burner, and while it maybe utilized for any suitable purpose, it is especially designed for use in connection with heating stoves. The main object of this invention is to provide a simple, economical, durable and efiicient burner to be used for heating purposes. v V

Anotherobj-ect of the invention is to so construct the burner that it is self generating; nonwarpable, and will furnish substantially perfect combustion at either a low or high fire.

. A further object ofthe invention is to provide a flame spreader in connection with the burner, the said spreader being'lined with asbestos on its under side, and so constructed that it serves a tri-fold purpose, namely; as a spreader for the flame; to protectfthe bottom portion of the burner, and being lined with asbestosit acts as a self lighter for the burner. m

The foregoing and such other ob ects as may appear from the ensuing description are .attained by the construction, combination,

arrangement and location of the parts hereinafter more fully described, such as illustrated by the accompanying drawings, and particularly: pointed out in the claims appended hereto, it being understood that slight changes in the precise construction, proportions and minor details may be resorted towithout departing from the spirit or sacrificing any of the advantages of th invention. In the accompanying drawings forming a part of this specification it will be seen that 1-: V Figure 1, is a central sectional elevation of a heating stove with the improved burner embodying my invention shown therein, and showing in outside elevation of the pipe connections broken away in parts, and a portlOll Of the oil tank..'

Fig. 2, is a transverse sectional view taken through the burner on the lines 2-2, Fig. 1, looking in the direction of the arrow, and Fig. 3, IS an inverted plan of the spread- H10 plate detached from the burner.

imilar numerals of reference are employed to designate like parts throughout the several views of the drawings.

In carryingout my invention, as shown in F 1g. 1, the numeral 1 indicates the outer casing of a heating stove of any suitable or des r'able construction, and 2 is the base portlon of said stove. The numeral 3 designates the oil or fuel tank which is prefer- I ably located about four feet higher than the burner, in order to furnish the proper fuel feeding pressure to the burner, said tank be ing connected with the burner by the feed piping 4, provided with a suitable stop valve 5, and a fuel supply regulating valve 6, said piping 4 being fixedly connected to the interiorly threaded inlet portion 7 formed at the bottom portion of the burner 8, which is mounted in any suitable or desirable manner within the casing 1, at the base portion thereof, the main body portion of the said burner consisting of a single casting formed with an upper arch-shaped member 9, a vertical wall 10 at each side thereof, and a central inafter described. Formed within the base 'member is a horizontal fuel feeding duct 19 which communicates with a vertical feeding duct 20 formed in the right hand wall of the burner, said duct 20 in turn communicating with a horizontally positioned duct 21 leading from the righthand wall of the burner 100 to the central portion thereof, and provided with a downwardly extending outlet 21 for the discharge of the fuel. Arranged centrally of the burner 8 between, its inner wall 11 is a flame spreader plate 22, which is supported upon the upper surface of the circu- V lar base member 15, and suitably secured thereto by a plurality of pins 23, which pass through theopenings 2 1 and fitted into corresponding openings formed in the base member. The flame spreader plate 22 is formed with a recessed lower surface 25 for the reception of the asbestos wicking which is coiled within the recessed portion of the said plate in'convolute form with each of its terminal endportions passing through an orifice 26 formed through the said plate, the other orifices 26 being also filled or plugged with asbestos wickingL I p I From the foregoing description taken in connection with the accompanying drawings, it will be readily perceived that the oil is first fed through the pipe 4: into the horizontal duct 19, from thence into the vertical duct 20, thence into the horizontal duct 21, from'whence it is discharged through the outlet 21 into contact with the flame spreader plate 22, and as the oil is discharged from. the outlet 21 it comesinto contact with a volume of air which is passing through the outlet '12 formed through the wall 11, thus creating a downward blast of commingled air and oil, thereby producing a fuel vapor which becomes ignited over the flame spreader plate 22, and produces an intense heat. I

jVVhenthe burner is first lighted the oil burns on the spreader plate without emitting smokeor odor until the burner is hot, and as the feed of the oil is increased the flame spreads and burnsthrough theorifices' 16,

17 and 18, thus forming a solid blaze substantially over the entire circle of the 7 burner.

:It' will be obvious that the volume of air flowing into the arched air chamber prevents the arch member from warping, while the orifices 16, 17 and 18 formed through the circular base member serve to prevent said base member from warping, and the flame spreader plate being lined with asbestos wi'cking, and the openings therethrough being filled with said wicking it serves to fully 'protect'the base member of the burner and at'the same time the asbestos wicking acts 7 Iasa'self lighter for the burner;

I within the The burner is so constructed that there are no parts likely to get out of order, and the feeding duct-s may be readily cleaned by re moving the screw-threadedplugs 27 fitted I II threaded openings formed through portionsrof the burner walls.

it will be understood that it takes fromthree to five minutes for the gas to generate;

having a' series ofopenings of varying sizes therethrough and a horizontal fuel duct formed therein, a vertical wall formed at each end thereof, one of said walls having a vertical fuel feeding duct formed therein,

a horizontal fuel feeding duct secured'within said casting, said ducts communicating with each'other, an arched shaped air chamber forinedby and within the casting, a downwardly extended fuel feeding outletjwithin said air chamber, and air outlet formed in the center of the arch for the discharge of o the commingled air and fuel. V 2. burner for heating stoves comprising a single casting formed with an extended circular base member and a horizontal fuel duct formed within said base member,' a vertical wall formed at each end thereof, one of said walls having a vertical fuel feeding duct v formed therein, an upper "horizontal fuel feeding duct secured to one of said walls I within the casting, said ducts communicating with each other, an arched shaped air chamber formed by and within the casting, a downwardly extended fuel feeding outlet within said air chamber, anoutlet in the centerof the arch for the discharge of the commingled air and fuel, and a iflame spreader secured to the upper surface of said base member, j
