KEROSENE-OIL BURNER.
Application led February 20, 1924. Serial No. 694,065.
This invention relates to kerosene oil burners and 1t consists 1n the novel features and arrangement of the parts' as hereinafter described and claimed.
An object of the invention is to provide a burner of the character stated which is of simple structure and which includes means for pumping -a blast of air through a nozzle member and mixing the blast with a stream of oil in the nozzle member in an atomized conditlon. Thls mixture of air and oil 1s directed into the body of the burner proper where it is ignited. As the mixture moves' from the nozzle to the body of the burner proper, it draws'with it a volume of atmospheric air which supplies additional oxygen to the mixture and within the body of the burner proper and this additional supply of the oxygen facilitates combustion within the body of -the burner proper and produces an intensely hot flame therein. i
Means are provided for recovering any I l unconsumed oil which may accumulate in the body of the burner proper and this unconsumed or overliow supply of oil is returned to the source which supplies the oil tothe nozzle in the first instance.
In the accompanying drawing:
Figure 1 is a plan view of the kerosene oil burner. Y l
Figure 2 is a side elevation of the same with parts broken away and parts shown in let end of the intake 2aud a pipe 4 communicates at one end with the interior ofthe casing 3 and the opposite end of theA pipe 4 is disposed centrally at the inlet'end of `the nipple 2. The pipe 4 is smaller than the intake 2,,thereby providing space between the side andv the adjacent end of the pipe 4 and-'the intake. :A fan 5 is'journaled for rotation in the casin 3 and'its shaft 6 isan extension of, or is colncident with, the shaft of a motor 7. A. pulley 8 is mounted upon the shaft of the' motor 7 and is alined with,
a pulley 9 mounted lipon'the shaft of a` pump 10. "1A belt 11 istrained around the rot-ary movement from the shaft of 'the motor 7 to the shaft of the pump 10. The casing of the pump 10 is connected by means of a pipe 12 with a tank 13. A pipe 14 is also connected with the casing of the pump 10 and extends adjacent the intakek 2, passes through the side of the intake and is connected at its other end with a nozzle ldisposed centrally within the intake 2 and at a point Vspaced from the point of juncture between the lat-ter 2v and the body 1.' The reduced discharge outlet end 16 of the outer part 15 of the nozzle is disposed toward the body 1. An inner part 17 is .located interiorly of the part 15 with its walls spaced from the walls of the latter and the reduced outlet end 18 is alined with the corresponding end 16 ofthe part 15.' The air pipe 14 connects with the inner end of the part 17 Theilatter is greater in diameter than the pipe` 14.
' An` oil tank 19 is connected by means of a pipe 2O with the interior of the part 15 of the nozzle, the pipe 20 penetrating the side thereof at a point between the ends of the same. A pipe 21 may be provided for supplying oil to the tank 19. A return pipe 22 connects. at one end with the bottom of the bodyv 1 and connects at its other end with a collecting tank 23. A pipe`24 connects the tank `23 with the oil su ply tank 19. y The'gperation ofthe urner is asfollows': The motor 7 is started and the fan 5 is "rotated, an'd a 4blast of air is discharged through 'the pipe 14 into the intake 2. This blast carrieswith it,l air from the atmosphere which enters the intake through the space between its wall and the wall of the ipe 4 at the adjacent endsof these parts. v vhis blast, together with the air which is drawn in, moves over and along the mixing nozzle and entersA the body 1 of the burner. `At vthe same time, the motor 7 actuates the pump 10 and air is pumped from the' Teservoir or tank 13 through the pipe 14 intol the nozzle part 17. 'The blast of ail.` is discharged from the outlet opening 18 mto the end portion of the part 15 and creates a partial vacuum within the nozzle. This vacuum draws the oil through the pipe 2O from the tank 19 up into thefbody of the nozzle and the oil lwhich is accumulated therein is sprayed through the outlet o enin 16 into the blast of air, hereinbefore escri d,.fwhich is moving throughfthe intake 2. The mixture is pulleys 8 and 9 and is adapted tontransmit 2U crank casing of an automobilc.`
ignited within the body 1 and produces an intensely hot lamea In that the currents of air move at slow velocity through the pipes, nozzle, intake, the burner isquiet in 'its operation and roaring noises are eliminated.
Anv overflow of the oil which may accumulat'e in the body 1, flows down through the pipe 22 into the rtank 23 and from theI tank 23, thesaid oil may be drawn by the suction established through the pipe 24 into the tank 19 from which point it is again led tothe nozzle 15 as'hereinbefore described, and is reintroduced into'the body of the' burner 1;. i
While it has been stated that the burner is adapted-'to be used for consuming kerosene, it may in fact be used to advantage for burning a mixture of fifty percent kerosene and {if-ty er cent waste oil drained from the In fact the burner may be used to advantage for utilizing as a fuel ,anyI other oil of a lower grade than kerosene. In further explanation of the operation of the device, it may be stated that any unconsumed oil from thel burner body 1` may pass through the` pipe 22 to the 'tank 23 and any overflow from the chamber 19 may pass through the pipe 24 to Ithe chamber 23. The chamber 23 may contain a fioat and as the level of the oil in the chamber 23 rises an electric circuit is broken at the contact 25 and thereby serving'as a signal and stopping the operation ofthe burner. The
`ameter of object of Vsuchprovision is to provide a safe guard to prevent the burner from operating if the oil '1s not being consumed or' if the needle valve in the float chamber 19 is not operating properly.` l
Having described the invention, what is claimed is:
In a fuel feed system ofthe class described, in combination, a head provided nipple in order that atmospheric air is drawny linto the-nipple through tlie\s\pace between the pipe and the nipple, an oil atomizing and projecting nozzle located within the nipple and having its discharge end-.disposed toward saidvhead, means for leading oil into said nozzle, means for discharging` a blast D of air into the nozzle for atomizmg and .spraying the oils into the air blasts passing through said nipples, and an ,oil return pipe connected with .the burner head and with the in drawing the oil through said return pipe. In testimony Vwhereof I aix my signature.
oil supply means for said nozzle, the air .blast leading to said nozzle, serving to aid ROGER M. HOPKINS.
