(Cl. 158-76) The purpose oi’ the invention is to provide a mixing well or ball adjacent the nozzle of an oil burner for thoroughly breaking up the air before it passes over the nozzle in order to obtain more 5 thorough mixing and more eiiicient burning.- Figure 4 is a cross section~on line Q-H of Fig ure 2. . Figure 5 is a detail showing a section through a portion of the air inlet valve. In the drawing the burner is shown as it may The invention is an oil burner nozzle in which the nozzle is positioned in a tube or surrounding be made, numeral i indicating the spherical mix ing chamber, numeral 2 the nozzle and numeral jacket and the surrounding `iacket is> provided 3 the electrodes. with a ball or spherical chamber directly behind 10 the nozzle, and the supply of air is forced through a chamber oiîset from the nozzle and opening into one side of said ball. Many devices have been provided for mixing ` The chamber i is of a spherical shape and is made integral with a tubular outlet passage â and a supply tube 5e connected into one side of the chamber i through an opening t. It will. be noted that air passing forward through the oil,with air, or atomizing the oil, or breaking _tube 5 will be directed downward by the curved surface ‘l atv the end thereof, and the air will 15 up _the air, however, substantially all'of these then pass into the chamber i and the spherical involve a mechanical mixer of some form or are in the form of venes to deiiect the air, howeven, surface of the wall thereof will direct the air around in a spherical motion so that it Will pass it has been found desirable to provide means ad jacent the nozzle whereby the air‘passes through back through the incoming air and then- pass out through the passage Q, and through the a churning chamber in which the, vchamber' is O opening i? around the nozzle,l with the vinner shaped to circulate the air through a sphere and then discharge the air through the incoming air.. surfaces ii oi the passage d directing the air in ward toward the center where it will again inter«` ‘ The object- oi’ the invention is, therefore, to pro vide means adjacent the nozzle of an oil burner mingle at a theoretical point id. At thevback for thoroughly. breaking up and :ce-mixing the of the chamber i is an opening ii covered with a cover plated? having screws i3 holding it in air before it passes around the nozzle. piace as shown in Figure 1, and at the back of Another object is to provide means for thor oughly breaking up air passing through an. oil the cover plate is a boss it through which the burner without moving parts or deñecting varies. fuel isl connected to the ,nozzle 2 through an in ternal pipe i5 and another pipe i6 which ex 30 Another object is, to provide means for thor 30 tends to an oil pump i'ë. It will be understood, oughly breaking up or atomizing air without ob structing the area of the passage through which however. that this connection may be formed in any other manner. The inner end of the pipe the air passes. , . A further object is to provide means for ‘thor-=` i5 is mounted in a spider or-stand i8 and the 36 upper part of the stand is formed with extensions 85 oughly breaking'up air in which the breaking i9 and 2@ in which the electrodes 3 are also held. up action is obtained by the shape of the inner The connections 2i and 22 from the electrodes surface oía chamber adjacent the nozzle. >With these ends in View the invention embodies - pass backward through a porcelain bushing ‘23, a passage connected with the exhaust oi a ian, a spherical chamber positioned at one side of that .may be held in. a socket 26, as shown in Figure 2, and the socket may be held by a screw _ the passage and adapted to receive air i‘rom the passage, and an. outlet lconnection extending from the spherical chamber and in which the of the casing and into a transformer 36 at one nozzle and electrodes arepositioned. - Other features and advantages of the invenè tion will appear from the following description, taken in. connection with the drawing, wherein: Figure 1 _is a View showing a side elevation of the complete burner. Figure 2 iS a cross section through the part oi the casing showing the spherical chamber with arrows indicating the path of air passing there through. 55 ' Figure 3 is a pian view o! the burner. ` 25 extending through the casing. The elec-v trode connections pass outward through the wall side oi"> the casing. ‘ . In the. design shown the opposite end of the supply tube d extends backward and the end- 0D posite the nozzle `forms a fan chamber 2l which is mounted upon a stand 28 and a motor 2l is also mounted on'this stand andidirectly con nected to a fan or .turbine in the housing 21, and also to thev fuel pump I1. It will be under stood, however, that the arrangement of the mo ' tor pump and transformer is immaterial as the ian or turbine, which may also be oi' any type 2 2,109,097 or design, and the pump, may be operated in any This mixing action is accentuated by the fact manner or by any means. that the chamber is spherical, or curved in all 'I'he volume of air passing into the device may` directions as the air downward at the be controlled by a valve formed of stationary ribs sides and at every point, also is churned around I0 and movable plates 3l positioned at one side . a sphere, as well as the air indicated by the of the housing 21 and these may be adjusted by lugs 32 and 33 in order to admit any amount of arrows at the front, thereby increasing agitation and ,producing more thorough mixing or breaking air desired. The plates 3l are held by screws 34 and 35 in slots 315v and 31, and it will be noted up there-oi’. ' Having thus fully described the invention, 10 that they may be moved around the center to - what I claim as new and desire to secure by Let# obtain any opening between the members 30 that may be desired. It will also be understood that this is only a typical arrangement of the valve, as any other means may be provided for con 15 trolling the amount of air admitted. It will be understood that other changes may .be made without departing from the spirit of the invention. One of such changes may be in the ters Patent, is: l ~ , In an oil burner o! the type having a horizon tally positioned nozzle at the end of an air tube, one end of which is connected to a blower for supplying airl under pressure, and the opposite end of which extends to a point adjacent the tire. and in which the nozzle is. positioned, and also in which said air tube is oiïset providing- two use of other means for connecting the ball or sections the axes of which are parallel, and with 20 spherical casing ofthe nozzle mounting in order the axis of the section connected to the blower to cause the air to pass around ina spherical above the axis of the section in which the nozzle motion and thereby mix or break up the air as it is located; a ball-shaped casingpositioned at the enters the nozzle, another may be in the use ot rear of the section in which the nozzle is located other means for mounting the nozzle and elec provided with an opening communicating with 25 trodes in combinationwith a spherical mixing said section, and also provided with an open-> chamber and still another may be in` the use of , ing in the upper side thereof communicating other means for supplying air and fuel to said with the upper air supply tube section, the wall chamber and device. _ oi' said upper section of the said air tube ter 'I'he construction will be readily understood minating at a point corresponding with and 30 from the foregoing description. In use this tangent on to the -theperiphery side adjacent of the the said nozzle, ball-shaped and device may be' provided as shown and described, Vcasing and although the supply tube 5 may be posi shaped to direct air currents passing through tioned at any angle, it is preferred to locate said casing downward at the front and sides of this tube directly- above the spherical chamber 35 I so’that the air passes directly downward into the interior thereof, and it will be noted that with .air supplied under pressure it will circu late around the wall and, as hereinbefore stated, passback through the incoming air so that a 40 very thorough mixing and breaking up of the air is obtained. said ball-shaped casing, and then outward through the section in which the nozzle is placed, the air passing around the inner surface of the said ball-shaped casing, and passingl through the current of air passing downward therein and section across the of said ñrstair named tube. opening from the EDWARD J.
