SUCTION BURNER WITH REGULATION OF OIL BY VARIATION OF LEVEL AND OF SUCTION FORCE.

Application filed January 17, 1925.

To all whom may concern:

Be it known that I, JEAN Anni a citizen of the French Republic, residing 63 Avenue des Champs Elysees, Paris, France, have 5 invented new and useful Improvements in a Suction Burner with Regulation of Oil by Variation of Level and of Suction Force, of which the following is the specification.

In the United States Patent No. 1,369,605

it has been indicated that the essential feature of the in vention forming the subject-matter of the said patent consisted in that the regulation of the supply of oil was effected, either by 15 separately varying the height of the column of suction of the oil or the supply of the air injected in the burner, or by simultaneously acting on these two variables.

In case the regulation is effected by modification of the supply of air injected, it has been indicated that the burner was constituted by a casing in which the air is admitted and which is open at one of its ends for the passage of an oil projecting 5 nozzle. This nozzle was dipping, at one of its ends, in the oil tank whilst the other end was combined with a cone, adjustable in position relatively to the corresponding end of the casing of the burner, for obtaining at will the proportions of oil. and air corresponding to the rate of combustion desired. But, if, for modifying the oil supply, the quantity of primary air injected is acted upon, an indirect influence is exerted on the quantity of secondary air sucked in the atmosphere and which is to be again.

regulated.

The present invention has for ob'ect improvements in this latter type of urner; these improvements essentially consist in combining the displacement of the cone relatively to the casing or to the oil projecting nozzle with the displacement of the obturators preventing the admission of air under pressure in the casing and the admission of secondary air sucked in the atmosphere; by the operation of a single member the increase or reduction of supply is thus obtained, without exerting any influence on the initial regulation ofthe combustion.

In the accompanying drawing and by waly of example:

igs. 1 and 2 illustrate respectively in Serial No. 3,134.

vertical section and in two half transverse sections according to lines AA and B-l3 of Fig. 1, a burner constructed in accordance with the improvements forming the subject-matter of the present invention.

As already indicated, the burner conr prises a chambered body a receiving the air under pressure and in which is arranged the oil projecting nozzle 0. But, in the device forming the subject-matter of the invention, the nozzle 0 is mounted on a bearing 7) forming a part of a body constituting a tank with overflow for the oil and a casing for the whole of the burner. For this purpose,this body is constituted by a cylin drical casing a terminating in a base Qt permitting to fit the whole on a furnace for instance. This casing of is provided with holes a and carries the pipe 7' for adduction of air under pressure. Its inner bore serves as a guide for the cylindrical. body a of the burner which is provided with a ledge, also cylindrical, having holes a corresponding to the holes a of the easing a A channel puts the pipe j in communication with the chamber in which is arranged the fixed nozzle 0, the open end of the chamber receiving the adjusting cone 5. The casing a is closed by a partition through which passes the pipe cl leading to the nozzle 0 on the one hand, and. dipping on the other hand, in the constant level tank e, separated by a partition. of the overflow vessel 0 The oil arrives in the pipe n in the first of these vessels, and the excess collected in the vessel 0- is evacuated through the pipe 0.

In these conditions, i f the body a is helically displaced in its cylindrical casing if, it will be seen that simultaneously are caused to vary:

1. The position of to the oil nozzle 0.

2. The section of passage for the air under pressure, owing to the displacement of the channel 7' relatively to the orifice of the pipe 7'.

3. The section of passage of the secondary the cone 6 relatively air owing to the displacement of the holes remain in the same proportions corresponding tothe .rate ofcombustion desired: neutral or reducing or oxidizing atmosphere. The realization of one or the other of these rates of combustion iseflected by previously adjusting the initial position of .the cone 5 relatively to the nozzle 0.

Fol-obtaining the helicoidal displacement of the body a of the burner, use may beinade of any suitable kinematic connection. In the case illustrated, the body a simply carries a claw m (extending in the shape of an operating handle) which fits in a groove y,

.of suitable shape, provided in the casing a For the control at a distance, the body a forming a key plug, cancarry atoothed segment ameshing With an operating crank 2 lVhat I claim as my invention and desire to secure by Letters Patent is:

1. In a burner operating by suction of the liquid fuel, a cylindrical casing, a sleeve co-axial With the liquid hydrocarbon feeding tube, a channel, in the said sleeve, surrounding the hydrocarbon feeding tube, a conical nozzle at the orifice of the said channel, a passage connecting the said channel with thetube for the admission of air'under pressure, a cylindricalflange forming an extension of the said sleeve, openings in the said cylindrical flange, corresponding ports in'the cylindrical casing guiding the sleeve for cooperating with the openings of the flange.

2. Ina burner operating by suction of the liquid fuel, a cylindrical casing, a sleeve coaxial With the liquid hydrocarbon feeding tube, achannel, in the said sleeve, surrounding the hydrocarbon feeding tube, a conical nozzle at the orifice of the said channel, a passage connecting the said channel with the tube forthe admission of air under pressure, a cylindrical flange forming an extension of the said sleeve, openings ,in the said cylindrical flange, corresponding ports in the cylindrical casing guiding the sleeve .for cooperating With the openings of the flange, and means for subjecting the said sleeve and its flange to helicoidal displacements rela tively'to the cylindricalguide casing.

3. In a burner-operating by suction of the liquid fuel, a cylindrical casing, a sleeve co-axial .with the liquid hydrocarbon feeding tube, a channel, in the saidsleeve, surrounding the hydrocarbon feeding tube, a conical nozzle at the orifice of the said channel, a passage connecting the said channel with the tube for the admission of air under pressure, a cylindrical flange forming an extension of the said sleeve, openings in the said cylindrical flange, corresponding ports in the cylindrical casing guiding the sleeve for cooperating with the openings of the flange, anrhydrocarbon feeding tube in communication with the constant level vessel and the opposite-end of Which cooperates Withthe conical nozzle, and means for subjecting the-said sleeve andits flange'to helicoidal displacements relatively to the cylindrical guide casing.

l. In a burner operating by suction of the liquid fuel, a cylindrical casing, a sleeve coaxial With the liquid hydrocarbon feeding tube, a channel, in the saidsleeve; surrounding the hydrocarbon feeding tube, a conical nozzleat the orifice of the said channel, a passage connecting the said channel with the tube for the admission of air under pressure, a cylindrical flange forming an extension-of the said sleeve, openings in the said cylindrical flange, corresponding ports in the cylindrical casing guiding the sleeve 'for cooperating With the openings of the flange, an hydrocarbon feeding tube in communication with the constant level vessel-and the opposite end of which cooperates With the conical nozzle, a helical groove in the Wall vof the cylindrical guide'casing, an operating rod, integral with the sleeve and its flange for cooperating with the helical groove and effectingthe displacements of the sleeve and of its-flange.

In testimony whereof I haveihereunto affixed my signature.
