VAPOR OIL-BURNER.

Application filed October 18, 1919. Serial N0. 331,6 49.

To all whom z'tmay concern:

Be it known that I, BENHOWER, a citizen of the United States, and a resident of Anderson, county of Madison, and State of Indiana, have invented a certain new and useful Vapor Oil-Burner; hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawlngs, in which like numerals refer to Y like parts.

This invention relates to vapor oil burn is an improvement on the inventlon shown in Patent No. 827,764, dated August 7, 1906.

The ob ect of this invention is to provide, by the rearrangement of the parts and the addition. of air vents, for the complete come bustion of the fuel in the structure described in the before mentioned patent.

The full nature of this invention Will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a central cross section of the improved oil burner ken on the line 1-1 of Fig. 2. Fig. 2 is a plan view of the burner with the reflectmg means omitted.

In the drawings indicates a pipe lead ing from any suitable supply of oil, such as kerosene or the like. ll-is a pipe leading therefrom horizontally and then vertically into the burner. A valve 12 is provided for controlling the supply of fuel to the burner. The vertically projecting portion of the pipe 11 is threaded at its upper end to receive the dome 13, the same having an upwardly extending rim 14 concentric therewith and a discharge outlet-15in the center thereof. The dome, While hollow, is rather thick and solid, especially in the upper ortion, so that it will hold considerable heat, and about its base there is a. series of Vertical air holes 9.

Under the dome 13 there is a drippingpan 16, preferably scalloped at 17 so that air may pass freely from the front of the stove in which the burner is located. In

the center of the drippin -panthere is acentral hole 18 through w ich the pipe 11 extends. Four stands or supports 19 are s need an equal distance from each other in tiie dripping pan 16, and notched or shouldered to receive and support what may be termed an oil ring or oil pan 20, which is Specification of Letters Patent.

Air passages 24.- are provided between the lnner rim 22 and the pipe gulde 23 by the guide supporting portions 25. The oil ring is also provided with a plurality in the form of tu es.

' he outer and upper edge of the ring 20 1S suitably rooved to receive and support a casing 2 lower portion and an enlarged tion 28 providing a combustion 29. A perforated heating plate pair of large outlet open- These latter openngs are coveredby deflectors 33 that are supported on legs 34, the same being notched at then lower ends'to rest loosely within the openings 32 and on the top of the plate 30.

he casing 27 is provided with a' pair of openings 35 registering with the openings 32, to provide for the introduction of additlonal air in the combustion chamber 29. The dripping pan 16 has two openings 36' provided in its base, and threaded in said openings are the tubes 37 extending upwardly into communication with the combustion chamber 29 through the openings 35.

From this description it is observed that the oil burner is provided with a plurality of air passages for vaporization and partial combustion of the fuel, and in addition there is provided the auxiliary air tubes 37 which supply oxygen to the flame in the mixing and combustion chamber 29 at a point where the flames are. coolest. Thisv provides for the complete combustion of the fuel before the flames pass out through the openings 32.

Herein it will be observed that the centralopening-18 not only su plies air to the combustion chamber throug the passages 9 and 24, but also supplies air to the tubes 26 as shown by the arrows in Fig. 1. With this construction a better draft through the tubes either the openings 32, 3 I or 18. The burl;-

of alrbopenings 26 herein shown the same having a flared let therein the oilas it passes 15 wherethan half 1. An oil burner comprising means for supplying oil thereto, a dome having an outand a portion over which the oil may flow, anoil pan dome and having a plurality of upwardly extending tubes for the admission of air, a casing concentric with and surrounding said dome and enlarged at its upper end to form a combustion chamber and having an airopening therein, a heating plate surmountin said casing and closing the same,

pan supporting said oil pan, said drip pan having allilif-OPGliiIlg therein, and means connecting said air openings in the drip pan and the casing.

2. An oil burner comprising means .for

11 andthe dome 13.

before it is entirely concentric with the h said plate havlng a flame'opening therein, a drlp,

supplying oil thereto, a dome having a discharge outlet and-providing 'a vaporizing surface for" the fuel, an oil-pan concentric with the dome and having a plurality of openings therein for the admisslon of air, a casing surrounding said dome and having an enlarged portion providing a combustion chamber, a plate having a flame opening and closing said chamber, said casing having an air opening therein registering with said flame opening in said plate, and tubular means secured in said casing air-opening and extending downwardly therefrom.

3. An oil burner comprising means for supplying oil thereto, a dome having a discharge outlet and a portionover which the oil may flow and be vaporized, a casing surrounding said dome and providing a combustion and mixing chamber therein, an oil pan concentric with said dome and beneath the same, said pan having a plurality of openings therein for supplying air to the mixing and combustion chamber, and a plurality of tubes extending downwardly from said casing for providing an additional supply of air to the combustion chamber for the complete combustion ofthe fuel.

In witness whereof, I have hereunto af-.

fixed my signature.
