Beit known that I, CONSTANTINE LEE .STRAUB, a citizen-of the United States, residing at Milwaukee, in. the county of Milwaukee-and State of Wisconsin, have invented certain new and useful Improvements in Suetion Gas-Producers, of which the following-is a specification.

, Thisjinvention relates to a suction gas "producer, of that kind in which air and wa-; ter vapor or steam are drawn into the body 'of-f ueland ther'esulting gas is drawn from he producer or generator by a gas engine or other means.

The object of my invention is to provide for generating gas of a more uniform qualitv or thermal va-lue and supplying the same in a more uniform stream or 'flow from the producer or generator to a gas engine or other place: of use, than has heretofore been attainable with such producers.

Another object of my invention isto provide for effectively andeeonomieally heatingair, spraying or' vaporizing water, inin-' jgling thespray or vapor with hot air and instantly converting it into steam in a theater by means of-waste heat o f the pro- 1 e1;i and the outfiowing hot gas, and sup such hot air and steam in a substan tial'ljyuniforni fiow'to the body of incan- ..de scent fuel in the producer for generating as.

a. vertical section, on enlarged scale, of the gas producer or generator, a preheater and a vaporizer or attenuator connecting the preheater-with a flash boiler or supenheater in the top of the producer. Fig. 3 represents a top plan view of the apparatus with parts in horizontal section. Fig 4 represents a horizontal sectionon lin e4-l, .Fig. 2, showing an annular fiue for outflowing hot gases. Fig. 5 represents-a vertical section of the top of the producer .or generator,

Fig. 6 represents a transverse section, on an enlarged scale of the equalizing pipe 12. on line -6 Fig. (3. Fig. 7 represents a sectional side elevation of the same. Fig. 8 represents a transverse section of the vaporizer on line 77, Fig. 6.

The gas producer A is constructed with the usual riveted plate-iron shell and fire brick lining upon a concrete foundation X,- and is provided near the base with a fire door a above the grate and with an ash pit door a" opening'into the ash pit a". The

ash pit is preferably provided-with a brick floor a,'but without a-brick lining, as shown. An iron top plate a is riveted to the ,outer shell and extends over the shell or casing of the flash boiler or super-heater C up to'the opening for the'fuel hopper. A filling of. fire sand is laced bet-ween t-heshelland the fire brick lining, as'shown in Fig. 2-. The top of the ash pit is made of an annular cast-iron plate or hearth B, supported onbrackets riveted to the shelland having a large central opening, into which is 'setrthe rocking or shaking grate B In a hanger Z) projecting from the hearth B and a suitable hearing in the shell is supported a rock shaft 12, to the inner endof which is connected a lever 7/ which con- ,nects with the shaking grate. To the outer end of shaft 1) is connected a hand lever b for operating the grate. w

" The inwardly projecting-annular hearth 13 forms a: contracted grate opening and prevents air or air and steam from passing up along the side walls of the producer; it

also serves as a support for the re-heater chambers Dland brick linin There-heater D while of notable utility,

extending down from the flash-boiler. By this arrangement the commingled hot air and steam which enter through pipe 0" are caused to passaround through the re-heater' chambers and become superheated before escaping into the ash pit and passing thence up intothe body of fuel.

At the top of the brick lining is c011- vstructed a comparatively thin wall 6, Figs. 2 and 4, forming an annular gas outlet flue E, havingan "inlet opening 6 opposite the connection of the gas take-ofi' pipe H. Adjacent to this fine E, are riveted to the outer iron shell six cast iron brackets (13 suitably spaced apart for supporting the annular flash-boiler or super-heater G. The flashboiler is supported on the cast iron brackets, and in turn supports the fuel feed-hopper F, on the flash-boiler or super-heater C is the top closure sheet plate a so constructed and attached asto prevent the admission'of air at the top of the generator. This'is' an economical and simplified construction as it does away with an extra cast-iron cover, heretofore required, and reduces the cost of construction. The flash-boiler is preferably composed of two segmental half boxes C, C arranged over the annulargas -outlet flue E and projecting inwardly from the Wall 6 partly over the fuel-chamber E as shown in Fig. 2. 'These super-heater boxes have cast with them the vertical or downwardly flaring poke-holes 0, arranged in a as indicated inFigs. 2 and 3. These superheater boxes C, C are also provided with Ill inner upwardly projecting flanges 0 which serve as a bearing forthe outwardly projecting flanges of the discharge spout F of the fuel hopper. The top 'of the producer is made tight by a wrought iron plate a which is secured to the angle iron ring at the top edgeof the shell and is inserted between the interior flange 0 of the boxes and the flange 7' of the discharge spout and is also made tight around the oke-holes 0.

'The space between the top 0 the superheater boxes and the cover-plate at is filled with a packing e" of asbestosormineral Wool to prevent radiation from the flashboiler. The poke-holes 0 extending through the flash-boiler serve as braces and increase the heating surface thereof.-

By means of the construction shown and above described the hot gas passingfrom the body offuel circulates around, first undcr'the inwardly-projecting part of superli6z1it1" C, thence through-port e and back around under the outer part thereof, thereby high1y heating chamber'C before escaping to the take-01f pipe H. j

\Vhen the superheater is made of two segmental boxes a special form of ell inlet pipe J is provided, being so constructed as to connect with the interior of both boxes at their adjacent ends. The super-heater is also made as a single annular chamber C 'Wlth which. is connected the air and'vapor supply pipe J with valve 3', shown in Fig.

The fuel feed-hopper is composed of a body portion F, an upper charger F and a lower contracted discharge spout F projecting down centrally through the super- J heater into the fuel chamber, as shown m- Fig. 2. The discharge spout'F is. provided at'the top with'an annular flange f which rests upon the topv plate a on the flange c' of the'superheater chamber C. The charger F is mounted on the body portion F and 15.

provided with-a tight fitting cover 1'', a inorable bottom plate f", and with-.a' locking,

device arran ed to lock the closed hot- 7 D I 1 tom plate when the cover is open and to c11- gageand lock the closed cover when the botv tom plate is open and discharging fuel into the hopper.

A gas outlet pipe H connects with the annular gas flue E and with a speciallycom structed purge-valve I. with which is connected the gas take-off pipe H extending down through the pre-lieater shell K, which is supported upon-the concrete foundation X The lower end of pipe H is connected with a cross pipe or four way coupling H, which connects by pipe H with the base of the wet scrubber P; One branch of the coupling H extends through the shell of heater K and is closed by a removable coverplate 71, and another branch '71" projects down to the foundation ,and'i's, adapted to receive and the superheater- C.
