UNITED STATES JOHN R. FLAHERTY, OF-ST. LOUIS, MISSOURI.

OIL BURNER,

Application filed Kay 19,

To all whom it may concern:

Be it known that I,- JOHN R. FL'AHERTY,

a citizen of the United States, residing at the city'of St. Louis, State of Missouri, haveinvented'a certain new and useful Improvenient in .Oil Burners, of which the following is a specification, reference being had to the'accompanying, drawings, forming a part thereo a This invention relates to a certain new and useful improvement in oil-burners and has for its chief object the provision of an oil burner that is relatively simple, inexpensive, and compact in form and construction and eflicient and comparatively noiseless in. operation.

With the above and other objects in view, mypresent invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and pointed out in the claims,

In the accompan ing drawings, Figure 1 is an e evational view of an 011- burner embodying my invention;

Figure 2 is a vertical sectional View of the burner;

Figure 3 is a plan view of the burner; Figure 4 is a similar view partly broken away and in i section and. with the oilvaporizing disk and fan omitted,

Figure 5 is an enlarged fragmental view, showing the motor, fan, oil-vaporizing disk in section;

Figure 6 is a burner; and

Figure 7 is an inverted plan view of the burner-parts of Figure 5.,

Referring now more-in detail and by reference characters to the drawings, which illustrate a preferred embodiment of my invention, 1 designates the base of the burner, which is preferably in the form of a hollow frusto-conical casting cut-away or apertured, as at 2, for-purposes shortly app-tiring, and recessed at its upper margin, as at 3, to provide an annular seat for a ring-shaped lower shell-member 4 flanged and shouldered at plan view of the fanof the its upper margin, as at 5, to, in turn, provide aneannular seat for "a second ring-shaped or companion shell memberfi and for the .prefr erab y obliquely disposed legs 7 of a fourth casting 8 for the most part enc'irclin the upper she'll-casting 6, as best seen in F1 ure 1. The legs 7 are preferably dispose 1n the plane of. the inner periphery of the casting 8 and are obliquely continued upwardly for purposes shortly appearing.

1924. Serial No. 714,400.

upon the inner periphery of the casting 8 to provide spacers 9, for concentrically spacing the casting 8 from the encircled casting 6, the casting 8 preferably flaring outwardly at its upper margin, as at 10. Below the horizontal plane of the outer casting 8, the

encircled casting 6 is formed witha series of cut-outs to provide the shell with a plurality of air-inlets or apertures, as at 11.

Disposed in spaced relation within, and integrally joined by connecting-lugs 12 to the lower shell-casting 4, is a water-basin 13 formed in its end-wall with an out-let 14 communicating with a water exhaust-pipe 15 Ieading through the base-aperture 2 to a suitable place of discharge. 1

Disposed over, and supported by means of inwardly projecting lugs 16 on the shellmember 4, is a water-retaining or cap-member 17 apertured in itsend Wall, as at 18,

Seated in and pro ecting through the basin 13 at approximately its axial center, is a tubular-member or stem 19 that extends at its upper end through the aperture 18 to adjacent the upper margin of the encircled upper shell-cast-ing 6 and at its lower end has communication-with a pipe 20 lead ing from a suitable source of crude-oil or other fuel supply (not shown). v

Fixed on the stem, is a suitable bearingcollar 21, and disposed on the stem 19 and supported preferably for anti-friction rotation by thecollar 21, as best seen in Figure '5, is a tubular casting 22, preferably integral with which, atits lower end and disposed preferably somewhat above the horizontal plane of the upper margin of the basin 13, as best seen in Figure 2, is a so-called water- *wheel or turbine 23 comprising an annular series of suitable spaced blades 24. Leading through the base-aperture 2 and the end-Wall pingement engagement of the discharging water.

Carried by and suitably fixed to the upper end of the casting 22, is a disk 27 formed within its area with an integral series of ed around the stem 19 and thread-seate at its lower end, as at 29, upon and to rotate with the casting22, is a tubular-extension 30, fixed upon which adjacent its upper end is a burnerdisk' 31 formed with a multiplicity of annular perforations 32 and an annular series of approximately or so-calledmoon-shaped openings 33.

Connected to the upper end of the stem 19 by a- T-coupling or the like 34, and disposed horizontally over the rotatable burnerdisk 31, as best seen in Figures 2 and 3, is a stationary discharge pipe 35 provided with a series of discharge-o1ifices.36; and coiled within the upper shell-casting 6 with its one or lower end communicating, as at 37, with .the water-Suppl pipe and its upper end discharging t rough a reduced .or jet orifice 38 ,uponthe burner-plate or. disk 31, as seen in Figures 2 and 3, is a water-heating coil 39. I

In use and operation, the crude 'oil or other fuel supplied to the stem 19 discharges through the outlet-orifices 36 of pipe upon the rotating burnerrdisk 31, where either as liquid or vapor it is ignited, and where the various openings 32 and 33 effect a breaking up and s reading of the fuel. At the same time, un er the force of water discharging upon the blades 24 under suitable pressure through the nozzle-outlet 26 of the water supply pipe 25, the casting 22 and its carriedfan'27 and burner-disk 31*are rotarily actu ated upon the stem 19, some of such water supply discharging through the nozzle-outlet'38 upon the burner-disk 31 in a thin stream or jet initially cold and subsequently,

'after the burner has been in operation, as

hot water and steam. The apertures 11 in the upper shell member 6 permit the entrance of air, which, under the action of the fanblades 28, the latter being arcuated at their edges and, largely upset to extend obliquely to the rotating plane of the fan-disk, is forced upwardly through the openings of the disk 31. and thoroughly mixed with the discharging liquid or vapor fuel, effecting, in association with the discharging water or steam, a burning-of the crude oil with a clear, white, hot flame and substantially total combustion of the fuel without carbonand'smoke. Due also to the novel form of the fan-blades 28 and of the disk 31, the fuel is largely centripetally acted upon and driven inwardly towards the supply pipe .or stem 19, whereby more or less mtense heating of such pipe and 'its discharging fuel and consequent ready combustion there- "of are obtained. 1 may'add that the enficlosing shell member 8, whifih at its upper margin projects abovethe plane of the shell 6, functions to confine the flame and direct the same and theheat thereof upwardly.

I through'the' furnace, stove, or other heating structure within which the burner may be arranged, the base aperture 2 and the spaces between the basin 13 and shell 4 furnishing openings 11 in the ring orshell-member 6,

the air is given a so-called rolling movement as it is drawn into the shell under the action of the fan 27, which, I have found, greatly facilitates combustion.

My new burner is relative] simple in form, may beconstructed at low cost, and is exceedingly efficient in the performance of its intended functions. l

I am aware that changes in the form, construction, arrangement, and combination of the several parts of the burner may be made and substituted. for those herein shown and described without departing from the nature and principle of my invention.
