` ot' crude petroleum and which will regulate the amount ot' fuel burned automatically by the-pressure of the steam and accomplish other purposes hereinafter explained, and pointed out in the claims. w

ln the ,lrawings forming a part of this application, Figure 1 is a perspective View of my burner. Fig. 2 is a central vertical section of the burner-tip and portions ot' the connecting-pipes. Fig. 3 is a plan of a portion of the tip. Figs. 4 and 5 are detail views, in central section, of different parts ot' the regulating device. Figs. 6, 7, 8, and 9 are detail views of different parts ot' my burner. v

In the drawings, Fig. 1, 1 is the oil-supply pipe, which feeds the oil to the burnerthrough the strainer 2. A blow-off pipe 3 connects with the supplypipe below the strainer. These pipes are provided with cut-off valves 4 and ,5, respectively. The upper end of the blow-oif pipe is connected with the strainer by an improved coupling-joint 6, the details ot' which are shown in Fig. 9. This improved coupling consists ot' externally-th readed sleeve 7, having handle 8, which sleeve encircles the central coupling/ member 9, having shoulder 10, and rotates and slides thereon when operated. This sleeve screws into the connection 7, which vin turn is adapted to screw into the bottom of the casing of strainer 2. (Shown` in detail vin Fig. 6.) In the top of the casing of the strainer-chamber is screwed oil-tube 11, the other end of which is screwed into aperture 12 in the casing 13 f the valvechamber 14.

of the shape ot' an hour-glass. In the strainerl 'chamber'is the screen 15, through-which the This tube connects the strainerwith the valve-chamber, which is preferably oil passes. Surrounding the oil-tube and connected with the casing oi' the valve-chamber and with the casing of the strainer-chamber is the steam-pipe 16, -which forms a heatingchamber around the oil-tube. Connected with the casing of' the strainer'chamber issteampipe 17, which connects'with the steam-supply pipe 18, Awhich in turn is connected with the steam-supply. (Not shown.) Exhaustpipe 19, having cock 2O thereon to control the amount ofexhaust-steam which passes there-A through, is connected with the casing of the strainer-chamber, as shown in Fig'. 6. In valve-chamber 14 are revolubly mounted the tapering oil-valve 21 and the hollow tapering steam-valve' 22,` which are adjustably linited by bolt 23, so that they may be rotate-dtogether to regulate by a single movement of` the regulator, as hereinafterexplained, the

quantity of steam and oil passing therethrough. The oil-valve is provided with a transverse channel 24, which registers with the port 25 (shown in Fig. 8) in the casing of the valve-chamber and with a like port inthe opposite side of the said casing opening into the steam-blow-out pipe 26, which is connected with pipe 17, so that the oil-passage leading to the burner-tip and the oil'chamber in the tip maybe cleaned with steam. At right anglesto channel 211 and opening thereinto is a second channel, 27, which is adapted to connect channel 24 with the oil-tube 11 through port 12. Valver 21 is provided with stem 2S,

.which projects through the easing of the valvechamber, to which stem lever 29 is rigidly aixed. Steam-valve 22 is provided with al port 30, which is adapted to register and be cut 0E from register with an internally-threaded opening 31 in the'casing of the valve-chamber, in which is screwed pipe 32, the other end ot which is connected with pipe 17. The internal hollow of thesteam-valve is incornmunication with chamber 14, which chamber is in communication through passage' with chamber 34. in that portion of the casing of Athe valve-chamber which projects at right angies to the central line of thesteamand. oil valves shown in Figs. 7 and 8,. Screwed into the end of the casing forming chamber 34 1s is in'commumcation w1th passage 47 through the flanged-bushing 35, which provides a bearing-surface for the ange 36 of the internallythreaded eoupling-ring37,having handle 38.

This coupling-ring is adapted to be screwed upon the coupling member` 39, which has a central aperture 40 extending therethrough, adapted when in place to register with port 2 5. The details of the coupling member and the connecting parts are shown in Fig. 8. As shown therein, an oil-conduit 41 has one end screwed into aperture 4() and the other end in centrallpassage 42 of casing/43 ofthe burnertip, Fig. 2. A steam-conduit44 is also screwed into said coupling member and into the casing of'the burner-tip, as shown in Figs. 2 and 8, which forms a steam-conduit from the chamber 34 to the burner-tip, communication being had through ports 45 in the coupling member, as shown in Fig.'8. 'The lower flange on the tip-plug 46, Fig. 2, which has a central passage 47 extending longitudinally to nearly the top 4thereoic and registering with passage 42, is 'screwed in to the easing 43 of the bu rner- -tip, said lower ange 48 being externally Above Harige 48 ports 55. This cap is held in place by uut 56. Flange 49 is provided in its upper surface with an annular groove 57 for the reception of the oil-supply-regulating ring 58, which is held therein by the cap and may have a portion thereof out out, 'as shown in Figs.2 and .3to permit the oil to flow out of chamber 54. The under surface of flange 49 is provided with an annular groove 59 f'or the .reception of' theV steam-regulatingring 60, which 1s cut out to,

correspond with the oil-regulating ring, and the two rings are arranged one directly above the other, so as to permit the oil from the oilchamber to f'all directly upon the Ysteam issuing from the steam-chamber. The steamregulating ring is held in Contact with. flange 49 bythe annular lring 61, which rests on the' internally-threaded ring 62, which is screwed upon the exterior of' the tip-casing and supports ring 61 and holds it firmly in contact with the steam-regulating ring. When it is desired to have a circular flame, the oil and steam regulating rings are removed from the tip. When a f'anshaped flame 1s desired, the

portionl of' each ring 58 60, respectively,which is cut out regulates the size of the iiame, and the position in which they are placed in the tip controls the directionv inwhich the flame is projected. Portions ot' these rings may be Qn the top of cut out at difl'ereut points and a llame consisting ot' a number l|ets.shootingout. urdlfi'erent directions will be produced. Vlhe details ofthe Various parts ronstilul ing the burner-tip are connecting parts to and out of' the burner-tip.

A-portion of the steam passes through. pipe 17 into pipe 16 and heats the oil in pipe i1. Cock 2O on exhaust-pipe 1f) is slightly opened, so that a constant supply of' fresh steam will enter pipe 16 and circulate around the oilpipe. As work varies the steam-pressure in the boiler varies, and this causes a waste of fuel unless the quantity thereof' is regulated.

In my burner l automaticallyv regulate the supply of both steam and oil by the steampressure in the boiler. To accomplish this, I connect pipe T3 with pipe 26. lipe 63 connects with valve -chamber 64, in which is mounted hollow valve 65, to the upper end of' which is attached stem 66 of' regulating-piston Piston 67 has an upwhich is seated in guide-plug 70, which is held spring-pressed by spring 71, the tension of which is regulated by screw 72. Piston 67 is cut away at its bottom, as shown in Fig. 4; but the cut-away portions are not connected. In thelower portion .ofl piston-chamber68 is exhaust-port 73, While oppositely disposed thereto is supply-port 74, which is connected by pipe with'the regulating-valve chamber 76, having casing 76', in which is seated Valve 77, held normally spring-pressed on its seat by spring 78, the tension of which is regulated by screw 79. Openinginto valve-chamber 76 below valve 77 is steam-supplypipe 80, which r-uns to and connects with the steam-space in the boiler. (Not shown.) Valve-clramber 64 (see Fig. 5) is connected by pipe 81 with exhaust-pipe 19. with the top and bottom of piston-chamber 82 through ports 83 and 84. In this chamber is mounted the steam and-valve regulating piston 85, having stem 86, which is connected by an adjustable link 87 with lever 29. Now

when the pressure. rises above the pressure v required to perform the necessary work it exerts a pressure on valve 77 great enough to raise it olf its seat, which permits the steam to pass into piston-chamber 68 and raise piston 67 against the pressure of spring 7l,

which causes stem 66 to vraise'valve 65 to cover port 83 and uncover port 84. The steam then passes through port 84 into pistonchamber 82 below piston 85. The upper portion of the piston-chamber exhausts through exhaust; pipe 81 and the piston rises and It is also in communication v67, which piston is mounted in chamber 68,n having la casing 68'.

wardly-extending stem 69, the upper end of' TOO IIO

ris

.thc oil and steam pipes.

through connecting parts operates both the steam and oil valves to cut oil' the supply ot' both to the burner-tip, and thus reduce the amountof vfuel' burned, which soon causes such a reduction of steam-pressure in the boiiers that the pressure of spring 78 reseats Yto return the oil and steam valves to their normal position. Pipes 17 and 18 are adjustably connected together by the improved coupiing, (shown in detail in Fig. 9,) which provides, with coupling 6, a ready means for connecting and disconnecting the bu rner from When' it is desired to blow out the oil-passage leading to the tip and the oil-conduits in the tip with steam, the steam ley-pass is opened and cut-off cock 4 is closed. At the same time the strainer can be cleaned by steam by opening cut-off cock 5.

It will be noted that the commingled atomizing and burning steam and oil will envelop the oil-chamber 54, which 4is thereby transformed into a superheating-chamber for heating the oil before the same is discharged ulpon the steam-jet Jfrom the steam-discharge s ot.

Having thus described my inventioml claim as new and desire to secure byLetters PatentH l. ln a hydrocarbon-burner two valves having valve-Stoppers in shape the frustum of a cone, adjustabl-y connected together at their l smaller ends, and adapted to be lock-ed together whereby both valve -stoppers rotate as one, one of said valve-Stoppers being provided with a lever and being adapted to control the flow of oil to the burner-tip and the other valve-stopper being adapted to control the `Elow of steam to the burner-tip.
