To all whom it may concern:

Be it known that-I, "WILLIAM J. TAYLOR, of Chester, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Gas-Producers, of which the following is a specification.

My invention relates to apparatus for gasitying fuel for metallurgical and other operations of the type generally designated as a gas-producer, but, however, differing essentially from any of the producers heretofore constructml in that the use of brick linings is entirely dispensed with, and which apparatus, to be hereinafter fully described, I have designated as a metallic water-cooled gasproducer.

The principal objects of my present invention are, first, to provide simple and effective apparatus in which anthracite, culm, or 1n'in eral coals may be used with practical success as fuel for generating the heating or other gas, and in which sticking or clinking of the fuel or llOlimSOlllllllStlblG material to the wall of the combustion-chamber maybe obviated, and apparatus which may be driven to much greater capacity, and hence make gas with greater uniformity; cond, to provide simple and effective means for the uniform distribution of air, or stcamand air, into contact with ing combustion and for obtaining the best practical results in the making of gas for metallurgical and other operations; and, third, to provide means whereby the ashes and clinker or non-comlmstiblc material collecting may be readily and effectively disch rged from the combustion-chamber while the producer is in full operation and without interferciiice therewith.

casing, of cylindrical or other suitable form, supported upon a base or joined directly to and forming part of the base, having feet preferably resting in a receptacle filled with l l l 1 with one or more vertical sight-apertures with removable covers.

1 lower portion of the producer cool.

ithin the main metallic casing is provided a metallic combustion-chamber of suitable construction, supported by the plate carried upon the base; or it is secured directly to the main casing. Abutting against the interior rim of the bottom plate and between the combustion-chamber and the main casing is provided a rectangular bar, to which, by means of rivets or otherwise, the main casing is rigidly sccured to the metallic combustion-chamber. Between this chamber and the main casing a jacket is formed, supplied with water continually by means of a pipe, and with an overflow-pipe arranged so that the water, or

1 condensed steam and water, may be conducted off from the jacket into any suitable receptacle.

Secured to the bottom of and projecting downward from the top plate of the producer 1 is a cylindrical hopper for self-feeding the the fuel in a con1bustion-chamber for effectfuel into the combustion-chamber, consisting of outer and inner tube-sheets secured by means of rivets to an annular ring and the space between the two forming a water-jacket. This cylindrical hopper, suitably connected with the top plate, is provided with one or more openings for the admission and free circulation of water between the two tube-sheets thereof for keeping the hopper at all times 1 cool. My invention. consists of a metallic main 1 Extending upward through the water seal 1 and base of the producer is an air, or steam and water and designated as a water seal, for j the reception of ashes and clinker discharged from the producer. 'lhis main casing is provided with a top plate suitably held there upon and arranged for supporting the feed descent fuel.

air, blast conduit, the upper portion of which extends into the central coinbustion-chamber, and is provided. with a conical-shaped hood having narrow or inverted-Vshaped interstices therein for discharging air, or steam and air, from the main conduit radially, or nearly so, into the chamber containing the incan- Beneath this distributing dehopper and gas-discharge flue, and provided i vice, upon supporting and guide rollers, suit ably journaled in a bracket or otherwise carried thereby, is a revolving bottom. Above the revolving bottom, and secured preferably to the bottom of the base-plate, is a device for causing the ashes and clinker to be discharged over the outer periphery of the bottom into the ash-pit, or the revolving bottom may be provided with a series of vertical points or teeth arranged aroundthe upper surface of the same, and with a series of points depending from the base-plate and arranged so that a row of depending points will be immediately between a double row of vertical points of the bottom, in order that the clinkers deposited upon the bottom and coming into contact with these points may be more or less ground up, and, when the bottom is suitably actuated, together with the ashes, may be deposited in the ash-pit beneath.

This revolving bottom is provided with a ratchet surface upon its under side, and meshing therewith is a cog-Wheel secured rigidly to a shaft held in bearings provided therefor in the base and the bottom actuated by a crank in any suitable manner.

In order that my invention may be fully understood by those skilled in the art to which it appertains, I- will now proceed to describe the same with special reference to the accompanying drawings, Wherein Figure 1 is a vertical central section of a water-cooled gas-producer embodying the features of my invention. Figs. 2 and 3 are ,re-

' spectively vertical central sections, partly in broken section, of a Water-cooled gas-producer, showing certain modifications in the construction of a combustion-chamber and in the means for supporting and actuating the revolving bottom. Figs. 4 and 6 are respectively transverse sections on the lines a: x and y y of Figs. 2 and 3, showing the main casing, revolving bottom, air or steam blast conduit, and aportion of the mechanism for actuating the revolving bottom. Figs. 5 and 7 are respectively top or plan views of the bracket and wheels for supporting the bottom and the shaft and cog-wheel rigidly secured to said shaft and meshing with the ratchet surface of the revolving bottom for actuating the same by means of a crank.

Referring to the drawings, A is the main casing, preferably cylindrical in form, made of wrought-iron or of plate-iron in sections suitably riveted together and supported upon the flanged top-plate, Z), of the base B, as shown in Fig. 1; or the main casing, as shown in Figs. 2 and 3, maybe connected directly with the base B and form part thereof. The base B is provided with feet Z), resting upon the bottom of the dish-shaped receptacle 0, kept constantly filled with water, termed a water seal, for the reception of the ashes and clinker discharged over the outer periphery of the revolving bottom of the producer, to be hereinafter fully explained. v

To the top of the main casing A fits snugly a double-flanged annular plate, D, made of cast or wrought iron and so constructed and arranged as to form a receptacle for containing and maintaining a supply of water for cooling the top of the producer.

d is a gas-flue fitting snugly against an annular vertical rim, d, cast with the top plate.

6 is the bosh-shaped feed-hopper fitting into and held snugly against a vertical annular rim, e, cast with or otherwise secured to the top plate, D. This feed-hopper e is provided with abell, 6 which fits snugly against the bosh-shaped throat of the hopper e and is raised and lowered by means of a chain, e passing over one or more pulleys, f and f, at tached to a weight, f

Projecting downwardfrom and suitably supported by the flanged top plate, D, is a cylindrical self feeding hopper, G, having outer and inner tube-sheets, g and g, rigidly attached, by means of bolts or rivets 9 to an annular rectangular ring, g and as so arranged forming an annular chamber-or jacket between the two sheets for the free circulation of water admitted through one or more openings provided in the flanged top plate, D, for keeping the hopper cool. Around the periphery of the water-cooled hopper G and extending therethrough are arranged transverse fiues g for permitting any gas accumulating in the upper portion thereof to readily and continually escape into the gas-flue cl. In the top plate, D, of the producer, at suitable distances apart and preferably cast therewith, are sight-apertures It, provided with removable covers h, having eyes 712, for their ready removal for examination of the upper port-ion of the producer for any purpose that may be desired.

I is the central metallic combustion-chamber, supported upon the annular flan ged plate I) of the standard or base B. This annular base-plate b is T-shaped in cross-section, as shown in Fig. 1, with a peripheral rim, b and with an inner vertical rim, b forming an annular U -shaped channel for containing a supply of Water for keeping the lower portion of the producer cool. Between the main casing A and the combusti n-chamber I is a rectangular bar, I), which rests upon the baseplate 6, and the two chambers held solidly thereto by means of rivets or otherwise, and into the annular space J thus formed is admitted water, which freely circulates around and around therein, constituting What is termed a water-jacket, the water being admitted thereto through a pipe, j, extending downward from the flanged top plate, D, to

within a short distance of the bottom of' the water-jacket. Near the top of the producer and opposite to the water-ad mission pipe j is a pipe, 7c, as shown in Fig. 1, for discharging the water from the jacket 1 into any suitable receptacle.

The central metallic combustion-chamber, I, of cylindrical form in diameter, may be the same from top to bottom, as shown in Fig. l, or slightly taper inward from the bottom to the top, or in form that of two inverted frustums of cones joined to each other, so that the smaller ends constitute, respectively, the upper and lower extremities of the chamber, the greatest diameter of which will of course be at the point where the larger ends of the frustums join, as shown in Figs. 2 and 3, this largest part constituting what is generally known as the top of the bosh.

It will be observed in Figs. 2 and 3 that the main metallic casing, made of plate-iron or other suitable metal in sect-ions riveted together, extends from top to the water-seal ash-pit of the producer, and that the boshshaped conlbustion-chamber I is held in position within this casing by a Z-shapedme' tallic plate, 1', riveted or bolted to the throat end of the chamber I and to the metallic casing A in any well-understood manner.

Extending vertically upward through the water seal 0 and base 13 is a conduit, M, having upon its upper extremity a conical-shaped hood, N, either secured thereto or cast therewith. This conical-shaped hood N is provided with a series of narrow or inverted-\l-shaped interstices, 91 preferably increasing in number from. the apex to the solid base of the hood and extending therethrough for the free passage and discharge of air, or steam and air, by forced draft, radially or otherwise, into the incandescent fuel in the chamber I, for effecting combustion and obviating any sticking or clinkering of the non-combustible material to the wall of the combustion-chamber. This conical-shaped hood N in Figs. 1 and 2 is provided with a depending flanged annular rim, n.

O is a cast or wrought iron bracket provided with vertical rollers 0 and transverse rollers '0, suitably j ournaled in this bracket for supporting and guiding the revolving bottom P, having at the inner peripheral extremity thereof an upper flanged rim, p, extending upward under the conical-shaped hood N and parallel with the depending an nular rim n of the hood N, and as thus arranged the ashes and cinder are prevented from coming in contact with the guide-rollers 0, journaled in the bracket 0, provided with an annular sleeve, 99, encircling the casing of the conduit M and held rigidly thereto by' means of set-screws 0 and To the bottom of the flanged base-plate Z) are secured three or more depending scrapers, T, of any suitable form, and which are arranged so that the ashes and clinkers falling upon the revolving bottom from the combustionchamber may be readily and quickly discharged over the outer periphery thereof into the ash-pit beneath by the mere revolving of the bottom around and around by the at tendant in charge and while the producer is making gas. The revolving bottom P, of circular or other suitable form,may be provided upon its upper surface with a series of pro jecting points or vertical teeth, 192, as shown in Figs. 2 and 3, for grinding up the clinkers accumulating in the combustion-chamber and deposited on the bottom P, which, together with the ashes, may be readily discharged over the outer periphery thereof through the circular chamber B into the water-seal C beneath. The ashes and clinker discharged into the water-sealed ash-pit beneath may be readily removed therefrom in any well-understood manner.

It will of course be understood that the revolving bottom Pmust be located at a proper distance from the throat of the central combustion-chamber, I, and be in proportion relatively thereto, in order that the'clinker and ashes deposited thereon may be held thereby in a mass until the bottom is actuated by the turning of the crank to be described.

Upon the under peripheral surface of the revolving bottom P is provided a ratchet surface, p", and meshing therewith is a cog-wheel, p rigidly secured to a shaft, 17, held in a bearing, 13, provided to receive the end extremity of the shaft in the sleeve of the bracket 0, secured-to the conduit M, and in a bearing, 19 provided therefor in the base 13. This shaft 19 has a crank, 19*, by the operation of which the circular bottom P maybe revolved around and around, thereby effectually discharging the ashes and clinker into the water seal or ash-pit during the time that the apparatus is making gas without the slightest interference therewith.

In the air, or steam and air, blast conduit M are provided two or more dampers, R, operated by horizontal rods 4" and handles 0" from the outside of the base B, and as thus arranged permit of the change of course of the air, or steam and air, from the conduit M in an upward direction through the cylindrical chamberor base B, and the throat of the central combustion-chamber into contact with the incandescent fuel whenever it shall become necessary so to do. In the base .13, at suitable distances apart, are provided peepholes Q, provided with covers g, which may be removed to ascertain the condition of the fuel around about the conical-shaped hood N or the circular bottom P, or for whatever purpose it may become necessary to make an examination of the apparatus.

In Fig. 3 is shown a modified form of the conical-shaped hood N, cast with the blast conduit M without the depending rim n. The bracket 0 in this figure is provided with vertical supporting guide-rollers 0, and the circular revolving bottom P, with its vertical points 19 is provided with three horizontal traveling rollers, o, suitably journaled in brackets cast with the bottom, and when it is actuated by turning the crank 19 the rollers o, in frictional contact with the casing M, travel around and around in a similarmanner to those already described in connection with the bracket shown in Figs. 1 and 2.

Projecting downward through the inverted- Z-shaped plate 2', to which the combustionchamber I is attached, is a series of depending points, 5, which aid in cutting or grind ing up the cinder or clinkers. These points are perfectly arranged so that the upper row of depending points comes immediately above and between a double row of vertical points of the revolving bottom P, in order that the work of cutting and grinding the clinkers may be most successfully accomplished.

The mode of operation of the water-cooled gas-producer hereinbefore described may be explained as followsz-The producer is fired in any well-understood manner, and the fuel admitted through the hopper e, the bell of which is lowered a sufficient distance to permit of the free passage of the fuel to the central combustion-chamber, I, and when sufficiently charged the bell e is drawn upward snugly against the bottom of the feed-hopper and the air, or steam and air, by forced blast admitted through the conduit M and discharged radially, or nearly so, through the narrow interstices 12 provided in the conicalshaped hood N, extending upward into the central combustion-chamber, I, for effecting combustion, and the gas arising therefrom carried off through the gas-flue d in the top of the producer for utilization, and whenever necessary the crank 19 operating the revolving bottom P, may be revolved by the attendant in charge for discharging the ashes and clinkers from the central combustionchamber into the ash-pit over the outer periphery of the revolving bottom P, while the making of gas for metallurgical and other purposes is uninterruptedly going on.

It is manifestly obvious that the more im portant features of my present invention may be modified. For example, the stationary conical-shaped hood and the revolving circular bottom, instead of being arranged as shown and described, may be combined and scrapers revolved around the surface of the bottom without departing from the real spirit of my invention, and hence I reserve the right to modify these features in any manner that may be deemed best for carrying out the same in the more extended practice thereof.
