AIR-SUPPLYNG MEANS FOR LIQUID-FUEL BURNERS.
Application filed June 12;. 1914.
To all ir/mm i'f may mm/'12 Be it known that (HARLES BADIGUER, citizen of the l rcurh Republic, residing at fit-Denis, Department ot' the Seine, in France, have invented certain new and useful improvements in i-\ir-Su1i plying Means for Liquid-Fuel Burners; and I do hereby declare the following to be a tall, clear. and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the s; inc.
The air necessary 'for the combustion of petroleum and other liquid fuels, must reach the furnace intimately mixed with the petroleum. W'hen the liquid isinjected in the form of a conical sheet. finely atomized, the mixing is ellected by means of air injecting drums or tw vers completely surrounding the atomizer.
Good results are obtained if a movement of rotation about the axis of the atomizer is imparted to the air. To this end the drums have been provided with (.lirecting blades similar to those of a radial turbine or of a centrifugal fan. This system has one draw back: it does not permit'ot reducing the section of the passage for the air when the activity of combustion diminishes In order to eliminate this drawlmclc, it has already been proposed to surroiuul the drum with a sheath movable parallelly to the axis, pen Initting ot' the air passages being; closed c m; pletoly or to a greater or 1 Ar enter-it. This system, however, doubles the site of the drum because the sheath must be as long as the drum so as to insurea complete closure, while its own length is added to that of the drum when it is in the fully closed position; moreover, this system is only applicable to cylindrical drums and not to truncated drums which are frequeutl v used.
in the arrangement according to the invention a drum is used, the directing blades of which are movable after the manner of Venetian blinds. The moven'ient of the blades may be etiected positively; in this case, the drum must be arranged within a casing communicating with the air heating apparatus through doors shutting automatically in the case of flame returns. The movable blades may also be controlled by mechanism which resists the opening, but

not the closing movement so that they shut automatit-all. in the case of a flame return. In the accompanying drawings: l igiures- 1 and 2 refer to the first methoi'l of con-- trolling. Figs. and i to the second method. Fig. l is a vertical section on line XX of Fig. 2. is a vertical section on line Y-Y of Fig l. Fig". 3 is a vertical section on line 25-2 of Fig. 4. Fig. l is a vertical section on line LT of Fig. liieferring to if It and 2. on the fad ing 1 of the boiler. is mounted a drum. cle noted generally by the reference el'iaracter 2, and which formed by the var us devices hereinafter described t'or supp. 3 ing air to the. burner. "the drum is located in a rectangular box into which air is introduced under pressure from the heating apparatus.
The host is provided witha door it, i adapted to oscillate about a hinge 5; this hinge arr nd in such a manner that the two portions 43, have unequal areas. The lower portion 49 is wei hted in any suit. ble manner to retain the lai ger portion at the top. in the case of a flame return, it will he seen that it would act directly on the large surface of the door and shut the latter.
The burner designated by 6 is mounted concentrically with the drum Vithin this drum, a disk '7 is freely mounted on the rim 8 between the guide 9 and the air nnlar plate 10. Tlhe latter and a similar one it), are connected by the spacing rods l1-1'l, ll which carry, freely mounted thereon, the angle pieces 12-12, upon which the blades 1-3l3 are mounted.
The oscillation of the angle pieces and therefore of the blades is effected by the sinmltaneous displacement of the tappets l-t-li mounted on the disk 7, and engaging i'iotches formed in the angle pieces 12 -12. A not 15 is pivotally connected to the disk 7 by means of a tube 16 movable in an open; ingformed. in the face of the drum 2; this not receives a screw 17 which rotates With- ,ont advancing" in a pivotal connection 18 mounted on the, facing of the said drum, and which is actuated by means of the hand wheel 19 to control the passage of air.
Referring to Fig. .2, the blades 13 are in their extreme position of opening; h pushing the nut t the left, the passage of the air between the blades is diminished, and when the nut is at the end of its travel, the blades bear. against one another and the passage of air ceases. A vertical pointer not shown on the drawing, but which may be integral with thenut 15 indicates by its rectilinear displacement on the front face of the casing, the degree of opening of the passages. With this arrangen'ient a flame return cannot cause the closure of the blades, but the door P, P will close and thus interrupt any communication between the furnace and the heating apparatus, the door reopening subsequently under the pressure of the compressed air of the said apparatus.
Referring to Figs. 3 and 4:, the drum -20, the front circular face of which is spaced from the boiler'facing 1 by the spacing rods 20 -20 is not located in a casing and the inclined blades 21-21 are directly acted upon by the compressed air of the air heating apparatus. These blades arepivoted at 22-22 and in the closed position each of them bears onthe pivotal connection socket of its adjacent blade.
The pressure of the air of the heating apparatus causes-the blades to open, the degree of bpening being controlled by a notched disk 23 which rotates on a'bearing 24 between two guides 25 and 26; the disk is formed with as many notches 23 -23 as there are. blades 21-21 and each of these notches serves as a stop, for these blades which the compressed air of the heating apparatus drives. -A movement of rotation of the disk 23 is produced by a mechanism comprising a screw, anut and a pivotal connection 15,16, 17, 18 and 19 as in Figs. 1 and 2. With this arrangement, if there is a flame return capable of driving back the com;
pressed air of the heating apparatus, the blades will immediately close all passages and prevent the flames from leaving.
I claim:
1. Air supplying means for fuel burners comprising a drum coaxially disposed with respect to the fuel burner and having a plurality of spacing rods running substantially parallel to the axis of the fuel. burner and arranged in a circular series about said axis, an air-controlling blade pivotally mounted upon each of said rods, and means to adjust the positions of all of said blades, for the purpose described.
2. Air supplying means for fuel burners comprising a plurality of adjustable blades disposed substantially parallel with the axis of the burner and pivotally mounted in a circular series about the axis of the burner, and means to impart simultaneous movement to all of said blades, comprising a notched disk each tooth of which engages with one of said blades, and means to rotate said disk to adjust the positions of said blades.
3. Air supplying means for fuel burners comprising a plurality disposed substantially parallel with the axis of the burner and pivotally mounted in a circular series about the aXis of the burner, and means to impart simultaneous movement to all of said blades, comprising a rotatable disk, means to impart rotary movement thereto, and means whereby rotation of said disk simultaneously imparts movement to all of said blades.
In testimony whereof I ailix my signa ture, in presence of two Witnesses.
