To all whom it 'may concern:

Be it known thatl, JAMES H. doornen, e eitizerf of the United States, residing at- Brooklyn borough, New vYork city, in the county of Kings and State of New York, lieve invented certain new and useful lmi'ollowing is e. specification.

The generator,'in the forni shown in the drawing, is of the style ordinarily known as 'the lVilliinnson improved gas generator, ,lesoribed :incl illust-rated in Letters Patent ol". the United States, li'o. 767,212', issued Air gest S. l-(Jel, although the pipe sind valve connecrions, which more particularly forni the snlogect inatter of the present invention,

can be applied to gas generators of other types in which it is desirable to control the 'tion' of the blast through Various parte or `he generator structure, and` control the flow of from one part ol the generator to the other in the manufacture of Water gas. lin practice, itl has been found that it is frequently diiiimilt to meint-ain a suitable temperature in all portions of. the generator striicinre, for the reason that it frequently happens that the carbnreter will be overhealed and the snperheaier underlieated, or rice Versa, so that the heat will be Wasted in certain parte of the structure with e, conseJ quent Waste of Vhydro-cerbon oil and imperrect orniationof the resulting gos. .Another objection to gas generators of ythe ordinary construction is due to the fact that in firingh the charge of fuel, in the generator it is necessary for the blast to travel through the earbnreter and the sn-perheater prior to its discharge up the line, which devions path oltravel necessitates the einplo)'nientI ot' :1` heavier blast in firing than would otherwise be necessary. l A

The object-of thev present invention is lo so improve the construction of standard ygieee'by the provision oia suitable passages and valves, thatthe fuel 'body een be lired the generator structure, and so that the arbnreting and siiperheating chambers can be heated independent-ly of each other.

Another object of theinvention is to regnlateihe passage of't-hedecomposed steam through the generator structurey in such manner that the gases, generated by thede-v composition of the stenen-can be made .to lon' through. both the carbureter and super Specification of Letters Patent.

The drawing;l is a sectional elevation of the gas generator of the Vililliinnson tyiye, showing the arrangement of passages and voli-'es consitnting the subject inaiter oiE the present invention.

The carburetor and snperhcatcr are filled with the pzn'aied from one anoiherby a. vertical gartition wall 9. lnnneiflialely above the cnrbnreter is a mixing` ghainber 1), and innnednlely above lhe snperheaier is ze discharge chainber ll, from which extends a lateral discharge poss-age lf2 and a rertical tine 3 which extends through the solid root lll of the generator structure. is provided with `grate bers l5, below if. en are located the' nsnnl blast openings 16. The body ol' the generator is of the usuel vfornnition, 91ndfurther detailed description is deemed unnecessa'rjf'.

Connecting with the lateral passage 18, and immediately below the mouth'ot the pipe l?, :is a vertical blast pipe 't9 which connects with the horizontal blast header 20 extending immediately beneath the loor of the tire chamber, below the grate bars therein, from which blast header the blast is discharged through blast. arch walls 2l or in any other suitable manner. through a portor passage Q0 leading to a suitable blower or other source of supply.

Immediately above the lower lateral passage 'i8 is an intermediate lateal pipe or passage 22 which enters the wall of the intermediate chamber-i3, Vbelow the floor of the carln'ireter. lhe upper end of' the pipe or passage l? connects with a lateral pipe or passage Q3, which pierces the walls of the mixing chamber 10. ln order to control the flow ofthe blast and the constituent gases through the various passages, valves of any suitable type are provided. The lower passage 18 is'provided with a valve 24C; the intei-mediate lateral passage is provided with a valve 2:3; and the upper lateral passage is provided with a valve 26. As shown in the drawing, these valves are ot' wedge formation, but other styles ot valves, adapted to withstand excessive heat, can be employed.

'the present invention is not concerned with the means provided for regulating the supply ot ,drain and blast to the tire cbanr ber on the up and down runs, which regulation can be pertiori'iied in any usual well known manner.

ln lee, in initially tiring a body olI lueh;

Ithe blast can bc admitted below the tuch and the valves 2l, 2i' and '3H thrown open, the remaining valves being` closed? which regulation provides a direct passage tor theblast up, through and out ot the pipe l7. which dirict blast' ,seiw'cs lo (pliclv'l'v bringl the l'uel to a state ol' incandescenee. .\l'icr the l'ucl has thusl been initially kindled, the purge valve or cap can be closed and the valve 2t', opened, which directs the course o5" the blau into and down through the carburete:l

Air is supplied to the blast header is provided with a lvalve i ing the heated air and ga through the tlue passage 12%. This regulation ol'l the valves serves to heat the entire generator to the degree required for the gas matting operaA tion.

lt is obvious that ift' additional valves were not provided the earbureter would be heated to a greater degree than the superheater, by reason ot' the 'fact that the blast is initially discharged into the carburetor, the walls and checker-wirk ol' which will absorb a major portion ot the heat units prior to the passage ot' the blast up through the sul'ierheater. 'llrithout proper regulation, the carlnircter will tend to become overheated by the time the superheater has reached its proper heat, so that hydro-cau bon oil or vapor introduced into the earbureter will be overheated, and. in large measure, turned into lamp black, thereby wasting the oil andiinpairing the illuminate ing qualities o't'the gas discharged from the generator. ln these circumstances, it is desirable at times to by-pass the carburetor` and admit a blast, with its heated units unimpaired, directly into the superheater. To accomplish this result, the valves 2G 'and'.ZT are closed and the valves and Q9 are openelfh which directs the blast immediately through the intermediate chambers 3 and l and up through the superheater without materially atl'ecting the temperature ot the carluireter. The latter, having been heated vto the desired (.legree, will thoroughly volatiliae the liy(.lio-carlion oils or vapors which, in the lt'orin shown, are admitted from a pipe ill in the mixing chamber lt).

vWhen steam is admitted to the incamlescent charge ot t'ueh it will be decomposed into its -constitnent gases, hydrogen and oxygen. the latter olf'which will combine with the carbon otl the t'uel and pass oli' with the hydrogen in the t'orn'i of carbon mo.`
