om BURNER.

lApplication filed January 2 This invention relates to an oil burner for mixing air and oil vapor to produceI a cornbustible or explosivemixture anl particularly Lto the mixing of air With the vapors I 5 of petroleum oils such as kerosenen The object of the invention'is to provide an oil burner whichy will vaporize the oil and mix it with the air in, continuous quiet and eiiicient manner and Without the use of high 1Q pressures or small nozzles.

Further .objects and advantages of the invention Will appear from the following description taken in connection With the accompanying drawings in which Fig. lis an elevational yieW of apparatus illustrating one Vembodiment of the inven' tion with parts broken away and in section.v

Fig', 2 is a section on line A-A of Fig. 1. FiO. 3 is a View similar to Fig. l but b lillustrating a modification, and

Fig. 4 is a diagram showing a current supply and charglngsystem for the electrically driven motor. Inv the embodiment of the apparatus shown in Figs. 1 and 2 a vburner embodying this invention comprises a curved pipe 1 into Which'oil vapor passes from chamber 2 having vaporizing plate 3. ln pipe 1 the .oil vapor'is mixed with air passmg in the direction ofthe arrow and forced along as by fan 4 driven by motor 5; The outlet 1a of the pipe is' positioned under the vaporizer 2, 3 and a portiomof the pipe 1 so that the burning oil vaporizes the intlovving oil Vand-preheats the mixture of oil vapor and air. y l The iniow 'ofoil preferablyjs adjustable c as by sliding valve tj connected Lto oil pum-p 7 iny iioat chamber 17 by pipe 8 and to 40 the vaporizer 2, 3 by pipe 11 from which it flows onto the plate' 3. AAV gravity overflow pipe 12 returns any excess oil back to the reservoir float chamber 17 so that only vaporized oil can enter the pipe 1 and be t la. 'i 'The supply of oill to `float' chamber. 17 enters throughinlet 104 and iscontrolled b float .16 in usualmanner and thel ump may be driven 'by motor '5.throug gears. in 'casing lfidriving the vertical pump shaft 14'.. Y l The supply vof air enters through Windows 23 controlled byf the shutter ring'l whichv may be connected to the oil control v'alve link 15 so that ,the oil and A 151925. serial No. 3,5'81.

air ,supplywvill 'be adjusted together toaid in maintai' ing the desired'l proportions in the mixture to be burned. p

"Toignite the burner the motor-5' will be started and aI preliminary heating provided byn burning oil inthe saturated asbestos ring 18, which Will vaporize' oil in vaporizer 2, '3 and lignite the mixture into a flame above the gauze 9 to form the ame.

In the burning of oil according. to'this invention a mixture of oil vapor and air feeds-the Haine. In forming the mixture heated oil vapor is 'supplied to the stream of air and further heat may be supplied to maintain a high temperature of the mixturebut preferably below the ignition point so that combustion will not take place until the mixture passes the gauze. 9. 'llhe flame itself is then utilized to .supply further vapor tothe air vstream and so the process is continuous. There is noburning. of the oil as liquid or unmixed vapor and there is non/clogging of passages and no excessive Ipressure isneeded to supply the v`flame. By

this burning of theinixed gases the formation of soot and other deposits is avoided and combustion is' carried on in a clean,l etlicient and'noiseless manner..

The mixture of oil vapor and air produced by this invention may also be used as an explosive mixture, for Yinstance Yin internal combustion engines, In such case the suction 'of the intake manifold' of the engine may: be 'used to draw in the current of air as illustrated in Fig. 3 Where' the 90 pipe 1 .connected at one end to the intake mani-fold 'and at the other end has/air inlet Windows 23 controlled by the shutter ring 13. At an intermediate p'intfthe pipe 1 is provided with the oil vaporizer 2, 3 supplied with :oil by pipe 11 and drained` by overflow pipe 12. The vaporizer 2', 3 may be heated by any suitable means as by' the engine exhaust or by an 'oil burner as shown in'Figs, 1 and 2. In the latter case 100 the pipes 11'and11 and 12 and 12 and shutter rings .13 and 13 maybe connected for simultaneous control so that the greater thethrottle o ening at 23 the larger will be the burner ame, f

To provide electric current to event 'of interruption Whi urs on service4 lines, I have shojivnin g. 4 the main line 27,-switchat 28 when osed connectsf

Secondary'wind- Assuming battery 87 is below normal charge current from charger 31 will pass t0 contact 38 said contact being c losed due to tension of lspring 39, through primary Winding 40, to battery 37 to relay 34 and back to charger 31. e

As the battery 37 becomes more fully charged the current flowing through primary coil 4() decreases while that in secondary coil increases until spring 39' is overcome and contact38 is opened thereby guarding against over charging of the battery 37 In ease of failure of current coming from the main line 27 relay 34 becomes demag- Current 'from battery 37 fiows through contorv 5 and'back to battery 37.

I claim:

1. Anoilburner comprising an air supply pipe, an oil vaporizer connected thereto, and an oil supply pipe and an oil overflow pipe lconnected to said vaporizer, and means for heating said vaporizer comprising an extension of said air supply pipe adapted to pass the mixture of air and gas to a flame forming means beneath said vaporizer.

2. An oi-l burner comprising an air supply pipe, an oil vaporizer connected thereto and an oil supply pipe and an oil overliow pipe connected to said vaporizer, means for heatring said vaporizer comprising an extension of said air supply pipe adapted to pass the mixture of air and gas to a flame forming means beneath said vaporizer, and means for starting said burner comprising oil retainer means in proximity to said flamev forming means.

3. In an apparatus for mixing air with oil vapor or gas, the combination with an air passage of a vaporizer connected thereto,

means for heating said vaporizer, 'and means i for supplying oil to said va orizer comprising a float chamber, means or conveying oil from said iioat chamber to said vaporlzer, and means for carryin ofli any excess oil from said vaporizer hac` to said float charm ber.
