Application le October 10, 1916.

. drocarbon or similar oil or liquid is vapory The object thereof is to ized and burned. provide simple and edective means for carrying the purpose of the invention into effect. One of the chief features in the construction and arrangement of the mechanical features-is a series of two or more cham-A bers that are highly heated and through which the vapor from the oil passes with an increasing degree of iineness or attenuation so that the vapor may be said to be superheated one or more additional times after the first vaporization in the iirst chamber in order that it may be more effective for use in producing a strong and vigorous lighting and heating quality; and further, the invention may be said to comprise numerous details` and peculiarities in the construction, arrangement, and combination of the various parts, substantially as will be hereinafter described and pointed out in the ensuing clauses of claim.

In the accompanying drawing illustrating my invention:

Figure l is a vertical section of my improved vaporized oil burner.

Fig. 2 is another vertical section taken at right angles to the section of Fig. l.

Fig. 3 is a top plan view `of myA improved burner.

Fig. l is a horizontal section of my im- 'f `proved burner. f

Similar characters of reference designate corresponding parts throughout the different iigures of the'drawing. n

l denotes-an oil supply pipe for bringing oil to the burner from any suitable source, as, for instance, the tank or pressure chamber. The oil or liquid which is employed may be any vaporizable substance such as coal oil, kerosene, gasolene, andthe like, as my invention is not limited to any particular substance but .can be employed with -any oil Specification of Letters Patent.

which will volatilize-and pass into an inflammable vapor. Pipe l opens into a bowshaped or forked pipe 3 whose upright parallel branches enter and support the topf' mechanism of the burner, the immediate entry of the said sections of the pipe-3 being into a chamber et which is a circular passage in a horizontal casting y20, in whichcasting is also an inner concentric circular passage 5 with which chamber 4 communicates through lateral openings 6 in the Vwall intervening between the two chambers l and 5.

On the supply pipe l or at some suitable point below thebifurcated pipe 3 and below theother parts of the burner is a priming cup 2 consisting of a suitable shallow member designed 4to receive a certain amount of iniiammable oil or other iiuid which can be ignited for the purpose of assisting inthe initial vaporization of the oil passing upward from the pipe l through the pipe 3 in order that pipe 3 and the other parts may be heated very hot at the beginning so that the oil will quickly volatilize.

Suspended from the chamber 5 by being attached at two points to the casting 20, at which two points communication is made with said chamber 5, is al curved or bowshaped pipe 7 which preferably lies within the same plane as the forked or bow-shaped pipe 3 and which has the same general curvature as said pipe 8 (see Fig. l). It should be noted that while the passage of the oil and vapor through the pipe 3 is upwardly, as shown by the arrows, until it enters the chamber t and passes thence through the lateral openings 6 into the chamber 5, the passage of the vapor through the pipe 7 is downwardly, as shown by the arrows, through both of the vertical portions of said pipe until the low ermost curved part of the pipe is reached, where the same is provided with a nozzle 2l into which is screwed a burner tip 8 having therein a pas-7' sage 9 which terminates in a small perforation 10 at the upper end, through which small or iine opening the vapor is ejected under the pressure which drives it forward.

This tip 8 being screw-threaded is adjustadjust/ed, great liberty in respect to the details of vthe burner tip as well as other' parts being permitted.

The casting 20 has a central circular opening 22 immediately above the burner tip S, and said opening receives a cylindrical meinber 15 having a liange 23 thereon which rests loosely upon the edge of said circular opening22 and is in this way supported by the horizontal 'casting V20. Said cylindrical member 15 extends for a certain distance above the casting 20 and is provided below its cylindrical section with a conical or downwardly iaring section 1st which terminates ina tubular section 11 of smaller diameter than `the cylinder 15, said tubular section 11 being provided with two or more perforations or openings 1'2, and surrounding the tubular member 11 is a sleeve 2st having pertorations or openings 13 which register with the pertorations or openings 12xbutcan be adjusted relatively thereto so that the registry may be partial or complete as desired, and through these openings 12 and 13 and also through the lower open end Yof thetubular Lmember 11 air is introduced from the outside atmosphere, being sucked inby the upward rush otl the vapor tromthe ytip 8 which draws in the air along with it,

as shown by the arrows. In this way a large volume ot vapor is carried upwardly into the cylinder 15 and discharged at the upper nend ofthe same against Vthe top or cover 16 which is a casting having a central member that lies at a suitable distance above the upper periphery of the 'cylinder 15 and is integral with an annular tlange 25 which stands within a short distance of the upper periphery of cylinder 15 and is integral with an annular plate 18 which is supported upon the casting 20 by means of a :t'ew feet consisting of pins 17. The outer periphery ot' this annular plate 18 is spaced a short distance from a ring 19 which rests loosely upon the outer peripheraledge ot' the casting 20, being suitably indent-ed near its lower edge to allow it to engage and rest upon said castingQO, ,as is clearly shown in Figs. .1 and 2. ,By means ot this construction and combination, therefore, it will be Yobvious that as the volatilized or vaporized gas rushes .upwardly yin a vigorous way as an ascending column it will strike against the vtop or cap which will serve as a ba'ie plate and will direct vit sidewi-se so lthat it will .dow through the space between the wallQf .fand the ledge of the cylinder, 15, passing jthen downwardly underneath ,the annular plate 18 yandjbeing directed upwardly and `outwardly by the ring L19 so that an annular ringotgas will be ejected between the edge `ofthe plate ,A18 and thering 19. At this pointthe gasis ignited andthe flame created,

`which'latter will have a Vcircular form and willspread upwardlyand outwardly-with a arge and intense -roleree-refheat :the

The operation ot my improved v-aporizedk oil burner will be readily understood from the foregoing description of the constructionand arrangement of the ditiferent parts. rPhe use or" a certain amount ot priming fluid in the cup .will heat the upper portion of the burner exceedingly hot so that when the oil rising through the pipe3comcs into contact with the heated pipe and also with the other heated parts above, it will flash into vapor and this vapor will first enter the chamber d; it will pass thence into chamber 5 and there be superheated, which will ,more completely convert it into a line volatile condition, after which it will continue through the pipe 7 and emerge from the burner tip S through the minute orifice Ytherein in a very inespray, which will rush stoves, l do not intend to have ,it confined.
