Application iiled April `12, 1917. Serial No. 161,544.

To allwltom it may concern:

,Be it known that I, GEORGE ScHLEUssEL- BURG, a Subj ect of the Emperor of Germany, residing at Detroit, in the county of Wayne and- State of Michigan, have invented certain new and useful Improvements in Alcol1ol-GasStoves, of which the following is a specification, reference being had therein to the accompanying drawings.`

This invention relates toa vapor generator and has special reference to a device for generating vapor that may be used for hea-ting and illuminatingpurposes, particularly in residences and small compartments.

The primary object of my invention is to provide a gas generating device in which alcohol can be easily and quickly vaporized, atomized7 or converted into vapor that may be safely used for heating and illuminating purposes, and provision is made for utilizing any condensate fof alcohol in connection with the device or about a stove or a heating apparatus, so as to avoid waste and reduce operating expenses to a minimum.

Another object of my invention is to provide a generating device in which alcohol or kerosene or gasolene can be easily and 4 quickly converted'intoa vapor to be used as fuel for a stove or for illuminating purposes, andi in either instance thevapor is of such nature as to preclude asphyxiation or explosion should the vapr escape into a room or compartment. y

A further object of my inventionis to provide a vapor generating device wherein the parts are constructed and assembled with a view of reducing the cost of manufacture rand at the same time retain'those features by which safety, durability, ease of regulating and a high degree of .efficiency are secured. With such ends in view, my invention resides in the novel `construction tol be hereinafter described and then claimed.

Reference will now be had to the drawings, wherein y i Figure 1 is a front elevation of the vapor generating device associated with a stove and illumination vapor burners;

Fig. 2`is a vertical sectional view of the generating device; and V Fig. 3 is a detail sectional view of a needle or regulating valve adapted lto form part of the device. u y

In describing my inventionby aid of the are the obvious equivalent of those to be v hereinafter referred to.` y

In the drawings, 1 denotes a base provided with a cylindrical housing 2 which has` the top thereof formed with a central opening HIMsELr, ROBERT r.

3. In the housing 2 is an alcohol burner,

constituting a source of heat, and as shown the burner is in the form `of a large lamp having a receptacle 4 provided with a` detachable cap 5 lso that the receptacle may be 'filled with alcohol or Aother fuel. receptacle 4 has a burner 6 provided with a wick 7 preferably of the cylindrical type', that may be adjusted bythe usual wick feeding mechanism, generally designated 84 and operable vfrom the outer side of the housing 2. y, l

Fitted in the opening 3 of the housing 2 is` a lower casing 9 and mounted on the lower casing 9 is an upper casing 10. Supported within the lower casing 9 or resting on the burner of the receptacle 4 is lamain tank 11 provided with a vapor inlet connection 1Q anda vapor outlet pipe '13,the latter extending-.out of the lower casing 9.

The main tank 11 is formed witha central vertically disposed flue 14 with the lower part of the flue conicalv shape to provide clearance for the burner 6 and concentrate the flame thereof centrally of the tank 11 and upper casings` 9 and 410. The central flue 14 cooperates with walls ofthe tank Il in providing an annular chamber 15 and this chamber is adapted to contain alcohol.

which may be vaporized by the heated walls end `of thelcentral passage 19 is a gas tank 2O having a" peripheral chamber 2l' anda central passage 22;

and around the vertical axis of theI lower `vides a peripheral chamber 18 and a een ftral'passage 19. Extending into the upper The bottom of lthe feed -ta'nk i 16 has a depending Well portion 23 and comin-unieating ytherewith :are the lower(l convolutions of coiled tubing 21aird-f25,' theformerbeing arranged Within the latter and extending into the central passage. The upperconvolution of the coil of tubing 24 is connected to `the' bottom ofthe vapor tank 20,azn-dfthe top of this gas tank is connected by a pipe 26 to the connection 12 ofthe main tank 11,. said. pipe. extending4 through. the central passage ..22 ofthe vapor tank 20: and downwardly. through. the. iii-ner coil of. tubing '24. l The upper convolutionofthe outercoil `oftubing is connectedto=thebottom-.of the vapor tank 20.and vextendingintofthe topp. of the .vaportank 2Q is..an iinverted U-sha-pe .siphon r pipe 27, said .pipe Y extendiingci'nto-the chamber .18 of the feedtank ,16, so -asto remove .any liquid, lalcohol or condensate from lthe vapor tank to the feed tank.

. ,-Thetop of the feed tank16 isp'rovided `with detachable cap l28 .so thatalcohol. or

`'p40 employed .for confining'the heatl from the A24 and .25 respectively,

other 'fuelilmay be placed therein, and the sideiof said feed tank has a conventional form ,ofgage or sight glass 29 which permits ofthe level ofi alcohol-.Within the feed tank .being easily ascertained.

"At the top- .of the vapor-tank 20 is awconventional-form lof safety valve .3() `which permitsof .an excessive pressure xvithinthe tank QOopeningthe 4valve to alloWeXcess .vapori-to escape, and such `vapor entersa frusto-conical .shape chimney 31 fitted over the upper end of the shell 17. The. safety valve 30` is Vsimply .used as a safety .factor device, and 10 are` principally burner 6 around the inner Aand outer coils While the chimney 31 finishes olf the top of the device.

Thebottom' of the feedtank 16 isconnected by-av doWnpipe 32to .a regulating .valve .33 in vcommunication .Withthemain .tank 11. This `regulating valve, `as best Ashoavnin Fi-g. 3, may be inthe form of .a

' needle-.valve having a need-le. 34 that can be adjustedjy toregulate the passage ofkalcohol vfrom. the rfeedi tank 16 tto. the main tank 11. .It is :possible to set the needle 34, of the-regulatingV valve 33 to @admit a predetermined Aquantity f-ofaalcohol'- to the main. tank 11, .so

.as to maintain-a. predescribed level of -alcohol therein. As illustrating-the .use of the' vapor genery ating device there `is-.shovvnf in Fig. 1, a vapor burning Astove `.or.cookinglj-range 35 having the usual vaporburnersupplied by a horizontally disposed. pipe `36 [connected tothe lpipe 'Y1-3. `The `horizontally ldisposed vburner pipe L36 has suitable connections 37 with a drain pipe 38 thateXtendsiniothe housing 2 and is connected to the fuel -densatein the ftity of vapor to the chamber 18 of the f the said burner,

burner,said` drain pipe conducting any conpipe 36 back into the receptacle't of the lbur-11er.

Theipipe36tmaynalso=be connected to a suitable pipe 39 for supplying burners 40 for illuminating purposes.

-With the Wick 7 adjusted and quantities yof^alcohol in the receptacle 4:, the main tank l1 and the feed tank 16 the Wick 7 can be lighted'by opening a door 41 of the casing 9. The flame of the lamp or burner will impinge against'the wall `of the `flue`14,lthe coils 24 and 25, and the Walls of the central passa-ges'lQ and 22l of the tanks16 and 20 respectively. The alcohol Within the chamber 15 of 'the main tank 11 will be heated and vaporizedto .a certain extent' but the greatest vaporization of alcohol takes place in the coils '24 and 25. The vaporized alcohol from these coils passes into the Lchamber 21 and `from said chamber through the pipe 26 to the main tank 11, this tank supplying the stove 35 and the burners 40' through the medium of thevp'ipes 13, '36, and 3S). VThe alcohol'within the chaniberlS of theifeed tank16will'fee'd bygravity through the pipe 32 to the needle valve 33, and with the needle '34 of said valve properly adjusted,- a desired level ,of alcoholniay be maintained v'ithin the-chamber 15 of the main tank'11,`so that there Will always be sili'cient space Within the chamber 15 to receive vapor fromthe pipe 26 in order that it'may reach the pipe 13.

p Before there will be an excessivepressure ofvaporwithin the chamber 21 ofthe vapor tank 20, the pipe 27 ivil'l admita quanfeed tank 1 6, and should the'lamp or burner'be turned veryloW and a condensateor quantity of alcohol accumulate in the'bottom of the chamber 21, this accumulated alcohol will be siplioned to the chamber 18 of the .feed tank 16.
