It has been found that the burner openings are best formed through the lava strips in substantially the manner shown in Fig. l, as in this way a number of small independent flames arecombined to form a single cone and the heat is concentrated more effectually. It is desirable that screens be provided beneath the lava burner strips, as shown at 1?, in Fig.3.

With the construction of the burner in two or several parts it is necessary that a gas supply be established to the chamber o't each part, and this is accomplished in the present instance through supply pipes 18 and 19, these supply pipes leading "from three- way connections 20 and 21. To maintain an even flow of through all of tl e burner openings it is prei'iera le that the burner plate 17 be left blank above the discharge ends of these pipes 18 and 19, which pipes open through the bottom ot the burner members 5 and 6, so that the will pan. to the chambers thereof and will flow at uniform pressure through the burner openiu To supply gas to and provide for subscai tia-lly instantaneous generation and ignition at the burner, I provide generators and a subgenerator. in air box 22 is positioned beneath the burner ring adjacent the inner side of the open center thereof, and is di vided into three various compartments 23, 2 land 25. Generator tubes 26 and 27 lead from the outer side of the burner and have their inner ends received through openings into the outercompartments 23 and 25, a subgenerator tube being positioned intermediate between generator tubes 26 and 27 and having its inner end extending into compartment 24. The sub and generator tubes are sul stantially identical in construction, and as shown in Fig. 2, have heads 29 at their inner ends which are provided with small gas escape openings 30, union nipples 31 bein connected on the outer ends of these three tubes. bar 32 adapted to recei e the squared portions of nipples 31 and to support the outer ends of the tubes are carried by rods 33 which are connected on supporting, standard 1'. bar 34'is provided with grooves to receive and support tubes, not here illustrated, having connection with the nipples 31, and by which kerosene or other fuel oil is. supplied to the tubes. Wick case 35 of steel wire fabric or like-mater- "having shredded astestes packed in the center thereof as 36 is placed within each of the tubes 26, 27, and 28, and each tube has a strainer screen provided at 87 adjacent gas discharge opening 30.

The operation of the generator and sub generator tubes requires the application of heat to raise temperature sutliciently to gasify the volatile oil as it is carried along by the wick structures, and this heating of the tubes is accomplished through the burner structure best shown in Fig. 5. This struc-' ture includes elongated gas burners 37 and 38 located beneath generator tubes 26 and 27 and combination gas and liquid fuel burner extending beneath subgenerator tube 28. Gas is supplied to burners. S7 and 38 from. three- way connections 20 and 21, and biiirner 39 receives its gas supply through pipe 10. Gas pipes 4-1 and 12 open into chambers 23 and 25 in line with the gasdischarge openings from generator tubes 26 and 2?, and these pipes are looped down and back to join with connections 20 and 21. The g is pipe 40 is looped up wardly, as shown in 2, and opens into compartment 2% in line with discharge opening 30 of suliigenerator tube 28.

A hollow head 43 is provided in conjunction with burner 39 and has burners 41% and which are disposed beneath the inner ends ot generator tubes 26 and 27 and substantially in line with. burners 37 and 38. Pilot tubes and 47 lead from the gas chamber in head and have their burner tips adjacent the inner and middle rings of burner openings in the main burner. Combination burner 39 has wicks .18 extending along each side thereof to receive liquid fuel and to direct the flame therefrom against subgenerator tube 28.

n the use of my improved oil burner, the

ts are assembled in a furnace in the manand when the tube has been raised. to a generating temperature the valve of the oil supply thereto opened. As oil is supplied to the outer end ot the tube it is taken up and advanced by the wick formation therein,

and upon being brought to the proper-temof the air box and mixed with the gas";

The gas travels down through pipe 4 :0 and 7 is supplied to burner 39 and head 43. The gas flowing at burners 39, 44 and 45, and at the pilot tips on tubes 46 and 47, is lighted and these flames are kept burning atall times. The flame at burner 39 heats subgenerator tube 28 sufliciently to generate gas to supply this burner, burners 44 and 45, and the pilot burners. Burners 44 and 45 heat generator tubes 26 and 27 at their inner ends and keep the same sufliciently hot that when oil is supplied thereto the oil will be substantially instantaneously volatilized and an immediate supply of gas will be furnished through gas pipes 41 and 42 when oil is supplied to the generator tubes. A portion of the gas passing through these pipes is consumed by burners 37 and 38 to heat the generator tubes to proper generating temperature, and the remainder of the gas is carried through pipes 18 and 19 to the gas chambers of the main burner. As the gas escapes from the burner openings it is ignited by the pilots, and the burner shows flame over its entire area. If desired, the top of the air box might be made removable to give access to clean the gas discharge openings of the sub and generator tubes, however it has been found that the formation of carbon and the collection of other residuary matter within the tubes is almost negligible.

While, in the foregoing, I have described specific embodiments, and have mentioned only certain possible modifications, it will be appreciated that in practice I do not limit myself to such specific details as herein set forth, but may resort to any practical modifications falling within the scope of the invention as defined in the appended claims.

I claim:

1. An oil burner to be fitted for use in furnaces comprising a pair of substantially semi-circular burner members to be fitted within the furnace, and dove-tail connections by which the burner parts are readily moved vertically one with respect to the other and are held in assembled relation, said burner having burner openings to spread the flame and direct the same against the sides of the furnace structure.

2. An oil burner to be fitted for use in furnaces including with a gas consuming burner made in parts to be "more readily fitted within the furnace, dove-tail connections by which the burner parts are held in assemb ed position, and generator structure beneath the burner to volatilize oil to supply gas to the burner, said generator structure being vertically beneath and entirely within the confines of the burner to thus avoid obstructing and interfering with fitting and assembling the burner.

3. An oil burner for furnaces including with a gas consuming burner to be fitted in the fire pot of the furnace, supporting legs by which said burner is maintained at an elevation above the furnace grate, an air box supported beneath the burner at one side, horizontally disposed generator tubes to be connected with an oil supply having their inner ends extended into the air box assembled by being and provided with gas dischargeopenings, gas supply pipes receiving gas from the discharge openings of the generator tubes and extended to conduct the gas to the burner, a subgenerator tube, a subgenerator burner located beneath the subgenerator tube provided with an extension head adjacent the air box, pilot burners on said extension head beneath the generator tubes, pipes from said extension head provided with pilot tips adjacent the burner openings of the main. burner, and a gas conveying pipe conducting gas formed in said subgenerator tube to the subgenerator burner and the extension head thereof.

In testimony whereof, I aflix my signature.
