HYDROCARBON-BURNER APPARATUS.

Specification of Lette'zs Patent.

Patented May 9, 1922.

To ali whom t may concern:

Be it known that I, C'ARLETON A. ORB, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State o f Colorado, have invented certain new and useful Improvements in Hydrocarbon- Burner Apparatus; and l do hereby declare the following-to be a full, 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 same.

This invention relates to hydrocarbon burners, the improvements being more particularly intended for use in connection with a water boiler or steam generator such as used in steam automobiles, although the improvement-s can be used in hydrocarbon burnersgenerally for which they are suited'.

One object of the invention is the provision of novel means for mixing the air and fuel, and to thoroughly atomize the fuel in so doing, whereby the mixture is' quickly ignited and the combustion thorough.

Another object is the provision of a hydrocarbon burner apparatus using a fan or blower for furnishing a copioussupply of air under pressure, and novel mea s whereby such blower is operated automatically to supply air when fuel is delivered, thereby simultaneously establishing the supply of air and fuel and likewise simultaneously cutting off such supply, under the control ofv an automatic pressure valve or the like.

A still further object is the provision of such an apparatus including a spark plug or igniter for igniting the fuel, andA automatic means for bringing such igniter into operation when the flow of fuel 'and air is started and for automatically cutting out such ig-A understood that changes can be made within the scope of what is claimed without def -parting from the spirit of the invention.

Figure 1 is a diagrammatical view of ther apparatus.

Fig. 2 is a fragmentary detail View showing a modification. f

The apparatus is illustrated as designed for use on a steam motor vehicle, but can be used for other kindred purposes, and, a's

shown, the apparatus includes a steam generator or boiler 1 having the burner pan or bowl 2 at the bottom (which may be lined with asbestos or other refractory material) and the smoke cap 3 at the top from which the chimney 4L extends for the outletof the product of combustion. The fuel is delivered into the burner pan 2 at one 'side through any suitable nozzle 5 from a fuel tank 6, and theapparatus' will burn kerosine, gasoline, alcohol, crude oil and other fuels, successfully. A pipe 7 leads from the tank 6 and has a manual controllin,-grv

valve 8 for establishing and stopping the:

How of fuel manually, and said pipe 7 leads" to an automatic pressure' valve 9, from which the fuel supply pipe 10 leads to the;`

the -tank '6 so as to flow under pressure-to and through the nozzle 5, and, for this purpose, the compressed air tank 12 is provided, and may be' dis osed next to the fuel tank 6. The tanks 6 an 12 have the respective pressure gages 13 and'lll, the air i-n the tank 12.

being under high pressure, whereas the pressure in the tank 6 is comparatively low. The' tank for convenience in pumping air Vinto said neck 16 throughwhichlth'e fuel ispouredl ljinto l:the tank. The air is delivered from 12 has a valve and hose connection' 15. s. 95,- y tank 'at intervals, and the tank 6 has aiilling` v tank 6, but restricting maintain a predetermined low pressure in the tank 6. The neck 16 has a valve chamber moved for filling the tank 6, the valve 2()` the a set of vanesl24 within'the delivery'porrtion of the'airv conduit `waste when the cap 21 is removed for filling etc. lVith the r the tank 12 into the tank 6 by means lof an airy ipe 17 leading romthe tank 12 and pre .erably `connected to the neck 16. A.

ressurereducing valve 18 is disposed in the piple 17 for the passage such iow s0 as Yto 1 9 therein into which the air flows from the pipe 17, and a check valve 20 is ldisposed in ligging normallyheld open4 ,by the Ccap 21 whic the chamber `19,

is removably secured on the neck 16, whereby when said cap is reis released so as to ,prevent -the discharge and ofair from the tank 12.v In this manner fuel tank 6, the flow of air-from the tank'12 is automatically stopped, 'and such tlow will be reestablishe'd when the cap 21 is again' applied tothe neck 16. 'The valves will deliver the uel the tank 6 to the deery nozzle 5.

chimneyI 4L' The air conduitV 23 extends from the blower 22 and delivers the air into the burner pan 2 opposite to the fuel nozzle 5, whereby the infiowing streams of fuel and air are directed toward Aone another in opposition, both the air and fuel beingunderA pressure. y nozzle 5V and the air` and fuelirnpinging,r against vone another, will result in the particles of -fuel being broken y11p-into a fine similar to .theaction of the windqwhen' striking water` delivered from mist or vapor',

a hosenozzle. which causes the drops of water to be broken into a fine mist. vln this way, the fuel is thoroughly atomized and mixed with the air, and ,n be lighted instantly without using a carbureter, va porizer, generator or similar appliance. This simplies burner plates, vvaporizer,

present arrangement, the fuel and air are delivered into they burner' chamber from opposite directions and this will vaporize the fuel and mii; thefuel and air thoroughly., It isxpreferable to' provide or pipe 23, which are twisted into helical'4 .orL spiral forni wherebyhrto '.givethe` stream of air a whirlf' ingr motionuthereby enhancing. th vaporizatioh'of'the fuel' and mixture of fueland air. The operating` means of 'the blower` 22l embodiesv anlelectrie an electrical circuit a hydraulic' '.or pressure of air into the uelI fthe lpressure is low,

`the burner and the Ation in steamV pressure in motor '25, disposedlin 26 having 'the battery" 27 or other source of electrical energy, and; switch 28'is'dis-fl more, the closure of the switch 28l enables 139 thereto a branch pipe'29-leading from the Jfuel supply pipe 10 at that side of the valve 9` opposite to the fuel Atank 6, Any suitable hydraulic or pressure switch can be used, whereby to normally open the circuit when v and to automatically close the circuit .when the pressure is inthe valvesS and 9 areopen, the pressure of the fuel vfrom the tan-k 6 will close the switch 28, in order that when the fuel is delivered from the nozzle 5, the motor circuit will be instantlvclose'd and furnish air at 'the is kdischarged into the whenthe `steam pressame time that fuel burner. Conversely,

vsure closes the `valve 9, to shut' off the fiow of fuel, the reduction 1n' pressure will auto? matically open the vlow 8, so as to stop the blower at the instant that the discharge of fuel is stopped. The fuel and air are thus automatically and simultaneously delivered shut ofi' according to pressure.

In order to'ignite the fuel when*` the flow of fueland air is started, 4a conductor 3Q 9()v Ais branched from 'the circuit'26 as a shunt f' parallelwith the motor 25, and has connected therein an electric automatic cut ofi' time switch 31 of any suitable kind, and the conductor 30' leads through the primary coil 95 of an ordi-nary or suitable spark coil 32, the switch 31 operating to' open the spark coil circuit after ythe current yiowsfor a short; The switch 31is normally closed, so thatvwhen the rent will `flow through both the motor `25 and spark coil 32, but the switch 31 will coil circuit after a short in-n terval whereas, vthe motor 25 lcontinues to operate. The secondary circuit 330i the 105k spark coil 32 is connected to the spark plu or igniterll, and the spark coil' 32,. wi

as usu'ahifmiucey a highpotential current 1n willA result in 'the igniterfi igniting the.' l fuel, it being noted :that the igniter is energized at the instant the .fuel is delivered into fiow of au started. In operation, supposing that the valve 8 `115 is Vclosed so that Vthe apparatus-is at rest,

To start the burner,.thezvalve 8 is opened,` and Ythe fuel will lowpastsaid valve 8 .and/'51 valve 9 through pipe 10 and nozzle 5;'.

and at the same time, the switch `26 is closedjl Lby the fuel pressure, thereby closing the' motor circuit and starting theI blower 22. Theair is 4thus supplied at the same time thatthe How of fuel is started, and, furtherswitch 28 is closed, the cur-v 100 or circuit 30, which' 110 of fuel for thoroughly 'fuel and the switch 28 will stop the blower.

. combustion chamber,

release the electric current to flow past the switch 3l thereby energizing the spark coil 32 which will result in the igniter 34 igniting the fuel immediately upon entering the burner chamber. The igniter 34 is stopped after a short interval, by the automatic opening of the switch 3l, and the ignition device is thus brought to rest, as it is no longer needed after the fuel is lighted, being only Abrought into operation when the flow of fuel and air is first established after having been cut down.- When the steam pressure increases 'to a point for which the valve i9 has been adjusted, said valve will be closed, thereby shutting olf the flow of then open to When 'the pressure of steam reduces; the valve 9'will open, there by recstablishing' theflow of fuel, closing the switch 28 to start the blower and, at the same time, energizing the igniter 34E, the same as before.

In the modification shown in Fig. 2, the

fuel nozzle 5 is locate-d centrally of the vanes 2l within the air conduit 23, whereby the air and fuel enter the burner chamber from the saine direction, and such venes will whirl the air around the discharging stream atomizing and mixf ing the fuel. This arrangement, however, will Anot have the advantage of the opposing streams of air and fuel striking one another as in the preferred form.
