IVILLIAM HENRY GONE, OF BERLIN, ONTARIO, CANADA, ASSIGNOR TO THE CONE GAS MACHINE (10., OF DETROIT, MICHIGAN, A CORPORA- TION OF MICHIGAN.

GAS-GENERATOR.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed June 7, 1905- Serial No. 264,173.

To all whom it may concern:

Be it known that I, IVILLIAM HENRY CONE, of the town of Berlin, in the county of VVaterloo, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Gas-Generators, of which the following is a specification.

My invention relates to improvements in gas-producing generators; and the object of the invention is to produce a fire-pot bottom which will hold the fuel up in the center, and so produce an equilibrium of heat in the side and center. To carry out this object, I have constructed and arranged my fire-pot bottom in the generator, as hereinafter more particularly explained.

The orawing represents a sectional perspective view of a lower portion of my generator, showing my improvement.

A is the casing of my gas-generator, which is preferably cylindrical in form and is provided for the major portion of its height with a firebrick lining A, surrounding the firebed, and peep-holes A so that the operator may be able to see the condition of the fire-bed.

A is a ring forming the bottom of the firebrick.

A is an internal casing forming the lower portion of the firebedthat is, the portion in which the ash falls. The casing A is proviced with an outwardly-extending flange A which is supported on an annular angle-iron ring A. The flange A has an upwardly-extending portion next the casing and forms an annular space around such casing and beneath the fire-brick. B represents a series of holes arranged in a circle and communicating with such annular space. The sizes of the openings of the holes B are controlled by a ring O, having a series of holes C, which are designed to register or partly register with the holes B, or the ring may be moved to entirely close the holes B. The means of turning the ring 0 is a handle C which is suitably connected to the ring and extends out through a slot in the side of the casing. These openings are designed for a purpose which will hereinafter appear.

D is the stationary bottom of the fire-pot, which is conical in form and provided with a projecting central portion D, which is hollow and extends in the form of a conduit down below the conical bottom and laterally to the casing, as shownat D having connected thereto a suitable flange-pipe D provided with a damper D".

D is a pipe or conduit leading from the annular space surrounding the ash-bed to the conduit D E is a conical grate, which surmounts the bottom D and is provided with a handle E, by which such gratev is shaken. It will be noticed that there is a space between the bottom of the internal casing A and the bottom edge of the grate to facilitate the discharge of the ashes.

The top of the conduit D is closed by means of a valve F, supported on a central stem F, having an eccentric end F through which extends the laterally-extending stem F, operated by a handle F It will now be seen by means of the handle F" the position of the valve F may be regulated, so as to allow of more or less of a draft through the center of the fire-bed, depending upon the condition of the bed as to incandescence.

By the form of my supportingbottom for the fire-bed the center of the fire-bed is, I find, kept substantially level instead of subsiding, as is usual in other forms of grates or fire-bed bottoms of which I am aware. I am also enabled, as hereinbefore described, to keep the bed of the fire level by means of the raised center of the bottom for the fire-bed and by changing the drafts of steam-laden air from center to side, or vice versa. I am also enabled to produce an equilibrium of heat from center to side and prevent airchannels from forming in the body of the fuel at the side and the deterioration in the quality of the gas produced.

I/Vhat I claim as my invention is 1. In a gas-generator, a fire-pot bottom of conical form extending from substantially the center downwardly to the edge and leaving an edge opening underneath the fire-pot and a correspondingly-formed shaking-grate superimposed on the bottom and provided with a suitable shaking-handle as and for the purpose specified.

2. In a gas-generator, a fire-pot bottom of conical form having a substantially cylindrical raised projection in the center, said I projection having an opening therein and a valve for controlling said opening.

3. In a gas-generator, the combination downwardly through the passage-way and means for raising and lowering the stem as and for the purpose specified.

5. In a gas-generator, the combination with a fire-pot bottom having a raised proj ection and a central air passage-way extending therethrough, of a valve extending over the central projection and passage-way, a

stem supporting such valve and extending downwardly through the passage-way, and provided with an eccentrically-formed lower end and a rod extendingtherethrough and provided with a handle outside the casing as and for the purpose specified;

6. The combination with the bottom of the fire-pot having a raised central portion and a vertical passage-way extending through such central portion of a conduit leading from such passage-way laterally outside the casing, a valve to close the top of the passage-way, and means for raising and low- 1eiring the valve as and for the purpose speci- 7. In a gas-generator, the combination with the fire-pot and casing surrounding the bottom of the same, an annular chamber surrounding the casing and communicating therewith through holes in the casing, and with a source of steam and air-supply, of a bottom for the fire-pot provided with a raised center and passage-way therethrough and communicating with the annular chamher, a valve covering the top of the passageway and conduit extending through the raised center and means for controlling the valve as and for the purpose specified.

8. In a gas-generator, the combination with the casing and fire-brick lining for the fire-pot, of a casing forming the lower portion of the fire-pot and having a series of holes arranged around the upper portion thereof and provided with an outwardly-extending flange forming beneath the firebrick an annular chamber opposite the holes,

.a steam and air supply in communication with the annular chamber and a ring provided with a series of holes correspondingly formed and arranged to the holes of the casing, and means for circumferentially adjusting the ring as and for the purpose specified.

9. In a gas-generator, the combination with the casing and fire-brick lining for the fire-pot, of a casing forming the lower por-.

tion of the fire-pot and having a series of holes arranged around the upper portion thereof and provided with an outwardly-extending flange forming beneath the firebrick an annular chamber opposite the holes, a steam and air supply in communication with the annular chamber, a ring provided with a series of holes correspondingly formed and arranged to the holes in the casing, ;means for circumferentially adjusting the ring and a firepot bottom provided with a raised center and passage-way extending through the raised center and communicating with the annular chamber aforesaid, and

a suitable valve located above the raised center and passage-way and means for controlling such valve as and for the purpose specified.
