will also thoroughly atomize this admired` l0 fuel and cause atomized fuel to have a rapid spiral flow out through the burner tip. This treatment of the oil and steam provides for a substantially conical jet of fuel at the burner tip, and gives the same effectivel form to the flame. The construction and arrangement of the atomizer and burner tip provide for a hot, effective fiame with a comparatively low fuel consumption, and without use of rotating parts.
An object of the invention is to provide an oil burner of the character described which will be strong,'durable and require little or no servicing over long periods of use. A further object is to provide an oil burner atomizer of the character described which will not readily clog and which may be readily andeasily taken outof and reassembled in the burner for cleaning purposes, this element being simple and compact as to form, and provides for a thorough breakingfup of the oil and as thorough an admixture of the steam or vair with the oil.
v Anotherobject is to provide a non-rotat ing, small, and compact vatomizer of the character described in which the steam or other iuid is fed under pressure thereto,-andv so treated thereby, that it will follow a spiral path in the atomizerv and `act upon the oil stream entering the atomizer so asto thoroughly break up the oil admiXed therewith and causey a large forceful jet of properly Vatomized fuel to: be discharged from-the burner. y f
With the above mentioned and other 0bjects in View, the invention consists'in` the novel construction andy combination of parts hereinafter described, illustrated in the aecompanying drawings, and set forth in the claims hereto appended, it being understood that various changesl inthe form, proportion',
size and minor details of construction within the scope of the claims may be resorted to Without departing from the Aspirit or sacriflcing any of the advantages of the invention.
Referring to the drawings: ,n

Fig. 2 represents a front end elevation of the burner.
Fig. 3 represents a sectional View taken on the plane of line 3-3 of Fig. 1, showing the front face of the atomizer.
Fig. l represents a sectional view taken onthe plane of line 4-4 of Fig. 1, showing the rear face of the atomizer.
Fig. 5 represents a sectional View taken on rthe plane of line 5-5 of Fig. 1.
Fig. 6 represents a side elevation of the atomizer.
The embodiment of the invention shown in detail in the accompanying drawings, comprises a steam pipe l, within which is mounted an oil pipe 2 of considerably less. diameter than the steam pipe. One end of the steam pipe is screwed into a nipple 3 on a fitting generally designated l, and the end of the oil 'pipe is likewise screwed into a nipple 5 on said fitting. On one side of the fitting is a nipple 6 which provides for connection of the fitting with a sourceY of supplyof-steam, air, orother fluid such as may be used with the oil, as is customary in oil burners, said nipple leading into a chamber 7 which communicates with the inner open end of the steam pipe 1.` A similar oil line nipple 8 is provided on the fitting and leads into a chamber 9 which communicates with. the open inner end of the oil pipe 2.
A sleeve 10 is screwed onto the 'outer end of the steam pipe so as to project `forwardly fromv the pipe, and a flanged sleeve 11 is .screwed on the outer end of the sleevelO so that its flange 12 will engage and hold in place, a disc-like burner tip 13. rfhe rear face of the tip plate 13 engages the annular wall 14 of a cup member 15 seated tight in ,the outer end of the sleeve 10, they bottom Aas or back 16 on said cup engaging and closing the outer end ot the pipe 1. Said cup has an inward extension 17 which is cored out and threaded to screw onto the outer end of the oil pipe 2.
An oil passage 18 extends through the eX- tension 17 into a circular depression or counter-bore 19 Jformed centrally in the bottom of the cup. A conical valve seat 2O is .provided at the intake end of said passage i18. A needle valve 19 is adapted to cooperate With the seat 20 and is carried on a valve rod 21 which extends through the oil pipe land stuiing box 22. Parts of the rod and stuffing box are screw threaded as at-28'fso .thatthe `valve 19v may be opened and closed on turning the valve handle 24.
Steam passes y.into the cup v15 through openings 25 formed in a circular series in the back or bottom 16 of the cup.
The especiallyk constructed atomizer element of thisinvention isv mountedinv 'the cup 15 and -is inthe forni of a small', circular disc or plate 2G, the periphery ot which engages the inner side oi"- the annular iva-ll 14, the baclr of which seats against the bottom 16 of the cup, and the frontiiace of Which seats against the rear face o the burner tip plate 13. Y
In the :frontr Vface of the atomizer disc 26 is aspiral groove 27 terminating in lthecenter oi' the disc in the form of anearly circular Well or depression 28. -An oil intake opening 29 is formed in the atomizerdisc 26 so as to open into the Well 28 near one side ofsaid Well, or better, near the inner end of the groove 27. Steam or air intake openings 8O are formed in the disc 26 so as to open at spaced points in the groove 27 nea-r the outer end ofthe groove, or at a point considerably removed from the oil opening 27, whereby the steam Will follow a spiral path before encountering the oil stream entering at the/opening 29. The groove 27 is ciosed on its outer side by the rear Jrace of the plate 13, and there is formed in this-Way, aspiral passage which opens into the well or depression 28. Through the centero'f the plate 13 is a burner orifice 32 orF a double inverted cone kor hour glass shape, which registers with the Well or depression 28 and thereby provides `for the oischarge from the burner of va large, swirling, conical oil jet. Y Steam from the pipe 1 passes through the openings 25 into the openings 30 formed in the disc 26, With which openings 30, the said Y openings 25 register. The openings 25 on the bottom of the cup 15 are so arranged that in the assembly, by placing the disc 26 into the cup 15, the same may be readily aligned in the usual manner to bri the openings 39 in registry With the'openings 25 of the cup The oil and steam are both delivered un- `motion as it is vdischa 1ged ont through the burner orifice. In this Way a large, forcible jet of fuel in conical form, is discharged with the,.oilthoroughly,broken up or atomized. No rotating parts are necessary due to the special atomizer construction in order to `thoroughly breakup the oil and to effectively ad'mix the steam therewith. This simpleA and inexpensive. construction is further 4advantageous, because it Will provide a great economy in fuel While causing aV large, hot flame to be produced at the burner. It will be noted that the burner construction, atthe top isy such thatthe atomizer Ais .effectively clampedinuplace, and fvvillnotrotate. This construction or" the burner atthe top, also facilitates theassembling and disassembling of theapparatus.
