i 011. BURNER.

Application filed December 12, 1925.

The invention relates to burners, and more particularly to the type of burners for utilizing a hydrocarbon fuel which is atomized by a fluid and vaporized by heat, the fluid mixing with the vaporized fuel to produce a gaseous mixture which burns with an intense heat, the flame being utilized in the industrial arts for Various purposes.

The invention provides a burner, embodyinga casing having an elongated outlet at one end and an inlet at the opposite end for steam or other fluid, and a tube within j the casing terminating at one end adjacent the outlet thereof vand connected at its opposite end with a source of oil supply, the tube being adjustable laterally at its outlet end with reference to the outlet of the casing to controlthe amount of fuel delivered in a given time.

l/Vhile the drawings illustrate a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied, and such other changes in V the minor details of constructiony may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof. y

For a full understanding of the invention and the merits thereof, reference is to be had to the 'following description and the drawings hereto attached, in which,-

Figure 1 is a top plan view of an oil burner embodyingthe invention, a portion of the header at the receiving end being broken away, p

`Figure 2 isa vertical, central, longitudinal, sectional view on the line 3 3 of Figure 1,

Figure 3 is a front view of the burner, and

Figure 11 is a detail sectional view of the delivery end of the burner on the line L1---4 of Figure 2. Y

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The burner comprises a casing 1 of tubular form and is enlarged at one end t-o provide a polygonal portion 2 for the reception of a wrench or Spanner, an outer flange 3,

outlet and, as shown most clearly in Figure 2, one end of the elongated outlet G termi nates in line with the inner wall of the casing whereas the opposite end terminates a short distance from the adjacent portion of the inner wall leaving a curved shoulder 7 which constitutes a deiiector to direct the steam or other fluid medium upwardly through the outlet 6 whereby to control the delivery of the fuel and the heat. The header is subdivided by a partition 8 to form chambers 9 and 10, the chambers 9 being in communication with the inner end of the casing 1 whereas the chamber 10 is adapted to be connected in any preferred way with a source of fuel supply. A fluid medium, such as steam, is supplied to the chamber 9 in any determinate way by means of a pipe 11 and such fluid passes through they casing 1 and discharges through the elongated outlet 6.

A tube 12 is disposed within the casing 1 and its external diameter is less than the diameter of the bore, or opening of the casing, so as to leave a surrounding space 17 between the tube 12 and the casing 1 for thel passage of the steam or other fluid. The tube 12 is supported at one end in the partition S and its opposite end terminates adjacent the elongated outlet 6 and the curved deflecting shoulder 7 and is adjustable laterally by means of a set screw 13 threaded in to a side of the casing 1. rlhe delivery end of the tube 12 is tapered and constricted, as indicated at 1li, to provide a reduced outlet. Liquid fuel from a suitable source of supply is fed to the chamber by means of a pipe 15 which may connect with the header at any determinate point. As shown, two pipes 15 are provided and one may be closed or connected to a source of steam supply for cleaning the tube 12 when required by shutting ofi' the oil and admitting steam into the chamber 10. An opening is formed in the outer end of the header in line with the tube 12 and is closed by means of a plug 16 and this opening admits of cleaning the tube by means of a wire when the accumulation cannot be removed by a blast of steam through the tube.

In the operation of the burner, a fluid medium, such as steam, is supplied to the chamber 9 by means of the pipe 11 and passes through the casing 1 and discharges at the outlet (i. Fuel supplied to the chamber 10 enters the tube 12 and escapes through the outlet lll and eommingles with the steam or other fluid, at the outlet 6, the resultan-t gaseous miXture being consumed as it emerges from the outlet 6 producingr a flame of great intensity.

It is observed that the steam is forced. through the Casing l around the fuel tube 12, with the same pressure at the opening 14, the steam below is given a greater or less volume by reason ot the raising or lowering of the outlet l-l. The raising of the outlet lll increases the volume of steam deflected from below by the curved detlecting shoulder 7 and thereby cuts oil' the flow` of oil, the volume ot' steam remaining the same,

-but greater amount being degected from below.

It is tui-ther noted that the shape of the casing l at the opening G is rectangular ai: the top and circular at the bottom, thereby direct-ing the liow of the steam horizontally at the top and upwardly and outwardly at the bottom, thus causing the steam from below to be more greatly saturated with oil than the steam from above, thereby producing a thorough and complete mixing of the oil and steam, immediately as it passes through the outlet 6 into the lire box, and the heat is equally distributed over the entire lire box, thereby producing the highest degree oiE elieiency and the highest consumption of the heat units from the fuel. To accomplish this, it is necessary that the outlet 6 be as indicated in Figure 3, viz: oblong in shape, the greater portion extending above the center of the casing l.

-As the oil leaves the outlet 14 it isy deflected upwardly into the main blast ol." steam escaping throughy the outlet 6 by a very small portion'of the blast which is 1diverted upwardly by the curvedl deflecting deflecting shoulder 7 cause an automatic diverting of the oil into the main part of the blast but it also creates an automatic control or' the lire as the steam pressure drops.

Having thus described the invention, I claim:

l. An oil burner comprising a casing having an elongated outlet terminating at one end in line with the inner wall of the casing and. having its opposite end spaced some distance troni the adjacent inner wall of the casing, a fuel supplying tube within the easing having its outlet adjacent the elongated outlet ot the casing and means tor adjusting. the delivery endy of the tube in the direction ot the length oi' the elongated outlet Ot the casing, whereby to regu-late the discharge ot lthe fuel.

2.` An oil burner comprising a casing having an elongated outlet terminating at one end in line with the inner wall of the casing and having` its opposite end spaced some distance from the adjacent inner Wall of the casing and connected thereto by a curved detleeting shoulder, a fuel supplying tube within the casing` having itsv outlet adjacent the elongated outlet and the inner` curved detlecting shoulder of the casing and means tor adjusting the delivery end of, the tube in the direction ot' the lengthy of the elongated outlet of the casing, whereby to regulate the discharge of'. the' fuel.

3. Au oil burner comprising a header divided by a partition to formA chambers, one ot the chambers adapted tofreceivea fluid medium and thev other chamber being con,- nected with a source of liquid fuel. supply, a casing` connected. with the Huid receiving chamber and` having an elongated outlet, a tube within. the casing and supported in the partition of the header and in communication with the fuel receiving chamber, and aset screw i-n a side'of thecarsing and adapted to adjust t-he delivery end ofthetube laterally to regulate the discharge oitv the fuel.

In testimony whereof I aliix my signature.
