To all whom @'15 may concern: l

lBe it known that ll, ABRAHAM BOX, a citizen of the United States, residing at Cherry Valley, Otsego County, New York, E have invented new and useful Improvements in Gas Producers, of which the following is a specification, reference being had to the accompanying drawings, in which-- Figure l shows a section of a machine ernlo bodying my invention; Fig. l shows in section a detailof the tuyre; Figi'. l" is a partial cross section of the machine showing the lifting blades; Fig. 2 shows'a partial section of a machine embod ing a modification of my invention, and iig. 8 is a rear elevation thereof.

` My invent-ion relates to inachineswhich .are capable of use in gasifying materials, and consists in the apparatus for gasiying and claim.

llfeerrin to the drawings, .2 is a metal shell or casing adapted to be rotated by any well known means, having a refractory liningx 3, which may be"equipped with buckets or lifting blades 4,' for lifting the material and distributino1 it as the Ivessel revolves. At the feed end of the vessel is a conveyer 6, by which the material is admitted, and at the discharge end is a 'fixed head 10, in the bottoni of which is a settling basin l1, and into which the ash dro s as is discharged from the cylinder.l t the feed end is an outlet l2 for the gas.

To prevent the entrance or leakage or" air or gas between the moving casing 2 and the stationary parts at each end l provide ilexible-joints 18. The conveyer 6 also so designed that it will contain suliicient material to prevenlL any leakage of airtherethrough;

At the discharge end of the conveyor is a tuyre lll, which is secured to the outer wall l5 of the head 10. The inner end projects into the interior of the vessel and. has a 45 downwaidly-turned nozzle 14?. The tuyere .is preferably provided with a water cooled jaclret 14 as is shown in' Fig. la. llateris supplied through the pipe 4leid and Withdrawn through the` .nozzle i451. rThe'nczzle 50 lll extends some distance below the top oil the fuel loe'd and serves to aerate and disturb the fuel 'and thereby assists in promoitm ing combustion as the vessel revolves. cess to the interior of the vessel is obtained 55, through a door i6 in thewall l5.

materials which l shall hereinafterdescribeI ses ramronnie.l .f`

ln the production of producer .gas-'in the apparatus just described, combustion is started jin the interior of the producer, fuel in the form of producer gas beingvsupplied if desired through the tuyere 14.'. When the interior or' the producer has become hot enough, fuel is 'fed through the screw conveyor 6 into the vvessel and the vessel is set in rotation. stantly exposes new surfaces of the materiel to promote combustion-and this action is greatly assisted by the air or other oxygen The rotation of the vessel con-- bearing agent from the tuyre y1.4 which, be i i cause of its downwardly directed end, always delivers a blast downwardly into the fuel bedand thus Lgenerates afzone of intense combustion immediately theres-bout. Thel tuyre 14 by reason of its downwardly directed end la, stirs also the material as the vvessel rotates and thereby assists in proinoting complete combustion.4 Wlith vliglfit fuels such es colre breeze, slack, etc., the blast from the tuyere tends to blow the inaterials away from the nozzle, but this is overcome by having the revolution oliA the vessel timed to keep bringing new fuel into the Zone of combustion. f

The passes rthrough the outlet l2, near 'the -Euel inlet end while the waste material passes out through the discharge end of the' vessel through the fixed head into the set-l tling basin 1l.

When the producer is 'used in the insinufactnre of water gas, air is supplied throiigh the tuyere lll to promote combustion, and when the fuel has become highly heated., steam is blasted in through the tuyra if desired, a coinbnsting agent for the water gas, 'suoli as oil, may be introduced with the steam. ,i The apparatus just described is partiew larly suitable for use inl aeifying such finely divided fuels' as coke refeze and. lignite slack, which are usually regarded es waste materials. Vvith such `inaterials a very complete gasilication has oliN tained. 1 Y f .

2 and 3, 'l have sho; .iisd form oi" apparatussuitaole outiny invention, in which j ortion of thc discharge end oit the is obstructed by a water-cooledsegment 1'?, which mounted on brackets 18 on thewall i5 o ie head 1G. Tuyeres /l are pro-- the segment, to permit oxygen soy 'i and not of limitation, and I have .no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof7 but recognize that various modifications are possible wit-hin the scope of the invention claimed.

l/Vhat I claim is:

vessel having an intake for the fuel at one endj and a discharge opening' for the wastel material at the other end,f al stationary l tuyre projecting through the discharge endl `of the vessel having a. doWnwardlyv turned- Water cooled nozzle projecting' downwardly intothe body of the fuel and arranged to direct an oxygen-hearing agent down into the body of ythe fuel beneath the nozzle to prom te gasification below the nozzle and also stir the material mechanically as the Vessel revolves.

2. Aga's producer comprising a rotary vessel having an intake for the fuel at one end and a discharge opening for the Waste :material at the other end, a. stationary the fuel.

memes tuyre projecting; through the discharge end of the vessel having a, downwardly directed water cooled nozzle projecting` into the body V an oxygen-bean of the fuel7 through which ing vagent is directed downwardly into the body of the fuel and below its surface, said nozzle being also adapted to stir the fuel mechanically,

3. A 'gasproducer comprising a rotary vessel having at one end an intake for the fuel and at the other end a Wall adapted to bank up the material in a deep fuel hed at that end, a water cooled tuyre at the dis charge end adapted to stir up the material and having an orifice through Which an oaygen-hearing` agent is distributed beneath the surface of the fuel, and an outlet for. the Waste material through which the Waste material from the surface of the fuel hed is discharged.

el. A gas producer comprising a rotary vessel havingan intake for the fuel and a discharge opening` for the Waste material, the discharge opening being' approximately on a level with the normal surface of the fuel bed, `and a tuyere at the discharge end having an orifice adapted to distribute an oxygen bearing agent beneath the surface of ABRAHAM s. ooX.
