UNITED STATES VINTSON G. PATTERSON, OF INDIANAPOLIS, INDIANA;

OIL BURNER.

Application filed March 4, 1924. Serial N0. 696,744.

To all whom it may concern:

Be it known that I, VINTSON Gr. PATTER- sox, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in Oil Burners, of which the following is a specification.

My invention has reference, in its broad aspect, to improvements in oil burners of the type wherein the oil is distributed in a thin film over an evaporating surface, and the vapor drawn down and mixed with air for combustion in a fire pan or tray. More particularly it is my purpose to provide an oil burner of this character, which will induce an exceedingly hot flame and eliminate the formation of carbon deposits.

In order to accomplish the foregoing and other equally important objects which will hereinafter appear, I have provided a hollow, semi-spherical, ribbed distributing member over which the oil film flows, and a hollow semi-spherical dome for confining the vapor eminating from the oil. The dome, however, serves a dual purpose in that 1t becomes intensely heated thereby completing vaporization of the oil, and it is formed with a lip which extends below the periphery of the first mentioned member to form a combustion chamber, and a guide for directing the flame in an unbroken circle in my fire pan or tray.

Another advantageous feature of my invention is the elimination of supplementary means for attaching the separate parts thereof. All of the parts of my burner are seated one upon the other and are held in position by their own weight so that they may be detached with ease for cleaning and the like, and'are unliable to become broken or deranged. Furthermore, my burner is formed without blind cavities or recesses which lend to the accumulation of carbon, and increase the cost of manufacture due to complication of the process of casting the parts.

To these and other nds, my oil burner consists in the construction, arrangement and combination of parts described hereinafter, illustrated in the drawings, and pointed out in the claims forming a part of this specification.

One embodiment of my invention is represented by way of example in the accompanying drawings, wherein Figure l is a sectional side elevation of my oil burner, t

Figure 2 is a top plan view of the assembly,

Figure 3 is a top plan view of the oil distributing member,

Figure 4 is a side view of the oil distributing member,

Figure 5 is a side view of my vaporizing dome, and

Figure 6 is a bottom plan View of my vaporizing dome. 1

Like characters of reference refer to like or similar parts throughout the several views I of the drawings, in which The numeral (1) designates the fire pan or tray of my burner which is circular in configuration and substantially dish shaped with a uniformly curved bottom rising centrally to an up-struck portion (2) formed with a central opening (3). The peripheral edge surrounding the opening is substantially flush with the top of the fire pan, and the fire pan is formed with an annular depending flange (4:) constituting a base upon which the burner is designed to rest.

The fire pan or tray (1) is formed with a plurality of ribs (5), here shown as three in number, and each rib is stepped as shown in Figure 1 to receive and properly support the remaining major parts of my burner. Upon the intermediate steps (6) of the ribs (5) a semi-spherical, hollow, oil distributing member (7 is adapted to be supported, and upon the apex of the member (7 is formed a circular raised portion (8). Radiating from the raised portion (8) and tern'iinating at the peripheral edge of the member (7) are a plurality of ribs (9) which are here shown as three in number, and formed beneath the raised portion (8) and depending interiorly of the member (7) is a boss (10) into which is adapted to extend an oil feed pipe shown in dotted lines at (11). The oil feed is of the gravity type, and the source of fuel supply is not here shown. Formed in the member (7) and communicating at an angle with the interior of the boss (10) are a plurality of openings (12) through which the oil is fed to the exterior surface of the member out to-rmation of'carbon.

(7) where it gradually distributes itself and flows downward toward the fire pan in a thin film.

In order to complete the vaporization of the oiland confine such vapors I have provided a semi-spherical, hollow dome or cowl (l3) which'rests upon the. ribs (9) of the member (7) and extends downwardly past the peripheral edge of said member to term a mixing chamber (A). The edge of the dome (13) is flared outwardlyand curved upwardly to form a lip (14) which is supported on. correspondingly formed steps of the ribs (5) of the'fire pan. The lip is designed :to direct the flame into the fire pan in an unbroken circle, and the dome (-13) is highly heated by such flame thereby completing the vaporization of the oil with- As shown in Figure 1, the feed pipe -11) is of-less diameter than the opening (3) through which it extends, and consequentlyyair is admitted to the interior of the member (7) whence it is drawn down memb r (7) between the fire; pan up-struck portion (2) and the wall of the member. (7), to the mixing; chamber. (A)., As the suction force necessary to draw inthe, air is directly pro.- por'tional to the intensity of the generated heat, the richness of the combustible mixture will be automatically regulated to insure the greatest, intensity of heat with the consumptien oft-he least amount of fuel.

I; Qperatiomthe fuel is simply fed by through the pipe (11) whence it passes throughzopenings (12) and distrib-v utes. itself upon the exterior surface of the The vapor is ignited as it passesthe lip (14,) of the dome (13) and as the deme becomes more intensely heated vaporiaation is increased to a point where entire process is a ied u most. c nomicallyand Without the formation of can hen deposits or the like. I In assembling or dismonnting the. parts of my burner they Pla ed. awn, er te off the tir Pa there being no. supplementary attaching means utilised. Furthermore it has been f nd n Pract t at my rn ore without noise, or the attendant roaring sound customary with this general type of burner,

While in theforegoing, there has been illustrated and described such combination and arrangement of elements as constitute thoroughly acquaint one skilled in the art with its construction and advantages, 1 claim? 1. An oil burner comprising a base provided with an opening and formed to provide fire pan, a plurality of ribs fOIIDBd on the base and radiating from a point adbeing provided with a plurality of steps, an oil distributing member seatable upon certain otthe steps of the ribs of the base and provided with'a boss above the opening in the base, said oil distributing member being tor-med with .a plurality of ribs and opening-s between the ribs .and communicating with the interior of the boss at an angle thereto, and a dome seatableupon the ribs o1 both the oil distributing member and the base. V

2. An oil burner comprising a base pro.- vided with a central opening and formed to provide a uniformly curved firepan, a plurality of ribs formed on the base and radiating into the fire pan from a point adjacent to the openin inv the fire pan, said ribs being formed with a plurality or steps, a semi-spherical oil distributing member sea-table upon certain of the, steps of the ribs of the base and provided with a boss, said oil distributing member being formed with a raised portion, and .a plurality of ribs radiating from the raised portion with ooenings formed betweenthe ribs and through the raised portion intocominnnication with the interior of the boss at an angle thereto, a dome sea-table upen the raised portion and upon the ribs of both the oil distributing ineu-ibe'r and the base, and a uniformly curved liip, formed on t he dome and seatable uponcertain of the steps at the ribs of thebase, said steps being curved to conforrn'to the cin 'vature of; the lip. r r
