tSPECIFIGATIOLT forming part of Letters Patent No. 709,782, dated September 23, 1902.

Application filed January 2Q, 1902. Serial Na 90,5 71. (N model.)

To (LZZ whom it may concern:

Be it known that I, LOUIS KELLER LEAHY, a citizen of the United States, residing at Los Angeles, in the county of Los Angelcs, State of California, have invented new and useful Improvements in Hydrocarbon-]3urners, of which the following is a specification.

My invention relates to that class of hydrocarbon-burners designed to burn crude petroleum with steam; and the objects thereof are to produce a burner that will burn all grades of crude petroleum and which will regulate the amount of fuel burned automatically by the pressure of the steam and accomplish other purposes hereinafter explained, and pointed out in the claims.

In the drawings forming a part of this application, Figure 1 is a perspective view of my burner. Fig. 2 is a central vertical section of the bu rner-tip and portions of the connectingpipes. Fig. 3 is a plan of a portion of the tip. Figs. at and 5 are detail views, in central section, of different parts, of the regulating device. Figs. 6, 7, 8, and 9 are detail views of different parts of my burner.

In the drawings, Fig. 1, 1 is the oil-supply pipe, which feeds the oil to the burner through the strainer A blow-off pipe 23 connects with the supply pipe below the strainer. These pipes are provided with cut off valves l and 5, respectively. The upper end of the blow-off pipe is connected with the strainer by an improved coupling-joint 6, the details of which are shown in Fig. 9. This improved coupling consists of externallythreaded sleeve 7, having handle 8, which sleeve encircles the central coupling member fl, having shoulder 10, and rotates and slides thereon when operated. This sleeve screws into the bottom of the casing of strainer 2. (Shown in detail in 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 of the valvechamber 14. This tube connects the strainer with the valve-chamber, which is preferably of the shape of an hour-glass. In the strainerchamber is the screen 15, through which the oil passes. Surrounding the oil-tube and connected with the casing of the valve-chamber and with the casing of the strainer-chamber is the steam-pipe 16, which forms a heating chamber around the oiltube. Connected with the casing of the strainer-chamber is steam-pipe 17,which connects with the steamsupply pipe 18, which in turn is connected with the steam-supply. (Not shown.) Exhaust-pipe 19, having cook thereon to control the amount of exhaust-steam which passes therethrough, is connected with the casing of the strainer-chamber, as shown in Fig. 6. In "alvechamber 14: are revolubly mounted the tapering oil-valve 21 and the hollow tapering steam-valve 22, which are adjustably united by bolt 23, so that they may be rotated together to regulate bya single movement of the regulator, ashereinafter explained, 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 thevalve-chamberand withalike portin the 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 may be cleaned with steam. At right angles to channel 24 and opening thereinto is a second channel 27, which is adapted to connect channel 24 with the oil-tube 11 through port 12. Valve 21 is provided with stem 28, which projects through the casing of the valvechamber, to which stem lever 29 is rigidly affixed. Steam-valve 22 is provided with a port 30, which is adapted to register and be cut off from register with an internally-threaded opening 31 in the casingof the valve-chamber, in which is screwed pipe 32, the other end of which is connected with pipe 17. The internal hollow of the steam-valve is in communication with chamber 14, which chamber is in communication through passage 33 with chamber 3% in that portion of the casing of the valve-chamber which projects at right angles to the central line of the steam and oil valves shown in Figs. 7 and S. Screwed into the end ofthe casing forming chamber 34: is the flanged bushing 35, which provides a bearing-surface for the flange 36 of the in ternally-threaded coupling-ring 37, 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 25. The details of the coupling member and the connecting parts are shown in Fig. 8. As shown therein, an oilconduit 41 has one end screwed into aperture tering with passage 42, are screwed into the casing 43 of the burner-tip, lower flange 48 being externally threaded for that purpose. Above flange 48 is a second flange 49, which projects beyond flange 48, the two flanges and the tip-casing forming a steam expansionchamber 50, which is in communication with the steam conduit-pipe through ports 51 in flange 48 and side passage 52 in the tip-casing. On the top of the tip-plug is mounted cap 53, which projects a little beyond and a little below the upper surface of the upper flange of the plug and forms therewith oilchamber 54, which is in communication with passage 47 through ports 55. This cap is held in place by nut 56. Flange 49 is provided in its upper surface with an annular groove 57 for the reception of the oil-supplyregulating ring 58, which is held therein by the cap, and may have a portion thereof cut out, as shown in Figs. 2 and 3, to permit the oil to flow out of chamber '54. surface of flange 49 is provided with an annular groove 59 for the reception of the steamregulating ring 60, which is 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 fall directly upon the steam issuing from the steam-chamber. The steamregulating ring is held in contact with flange 49 by the annular ring 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. WVhen it is desired to have a circular flame, the oil and steam regulating rings are removed from the tip. The portion of each which is cut out regulates the size of the flame, and the position in which they are placed in the tip controls the direction in which the flame is projected. Portions of these rings may be cut out at different points, and a flame consisting of a number of jets shooting out in different directions will be produced. The details of the various parts constituting the burnertip are illustrated in Figs. 2 and 3.

In the operation of my device oil is fed into the burner through the strainer, which removes all solid impurities which are too large to pass therethrough. Steam is also fed into The under the burner, and a portion thereof passes into the steam-valve chamber and thence through 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 11. Cook 20 on exhaust-pipe 19 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 I automatically regulate the supply of both steam and oil by the steampressure in the boiler. To accomplish this, I connect pipe 63 with pipe 26. Pipe63 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 67, which piston is mounted in chamber 68, having a casing 68. Piston 67 has an upwardly-extending stem 69, the upper end of which 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 the lower portion of piston-chamber 68 is exhaust-port 73, while oppositely disposed thereto is supply-port 74, which is connected by pipe 75 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. Opening into valvechamber 76 below valve 77 is steam-supply pipe 80, which runs to and connects with the steam space in the boiler. (Not shown.) Valve-chamber 64 (see Fig. 5) is connected by pipe 81 with exhaust-pipe 19. Itis also in communication 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 required to perform the necessary work it exerts a pressure on valve 77 great enough to raise it 06 its seat, which permits the steam to pass into piston-chamber 68 and raise piston 67 against the pressure of spring 71, which causes stem 66 to raise valve to cover port 83 and uncover port 84. The steam then passes through port 84 into piston-chamber 82 below piston 85. The upper portion of the piston-chamber eX- hausts through exhaust-pipe 81, and the piston rises and through connecting parts operates both the steam and oil valves to out 01f the supply of both to the burner-tip, and thus reduce the amount of fuel burned, which soon causes such a reduction of steam-pressure in the boilers that the pressure of spring 78 reseats valve 77. The steam in pistonchamber exhausts through port 73 when spring 71 pushes piston 67 to its seat, which returns valve 65 to its normal position, which permits the steam in the lower part of piston chamber to exhaust and the steam-pressure To be applied on the top of the piston to return it to its normal position and through connecting parts to return the oil and steam valves to their normal position. Pipes 17 and 18 are adj ustably connected together by the improved coupling, (shown in detail in Fig. 9,) which provides, with coupling 6, a ready means for connecting and disconnecting the burner from the oil and steam pipes. hen it is desired to blow out the oil-passage lead ing to the tip and the oil-conduits in the tip with steam, the steam by-pass is opened and cut-off cock 4 is closed. At the same time the strainer can be cleaned by steam by opening cut-oil cock 5.
