I, EDWARD BROOK of Clevelands Marsh, Huddersfield, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has reference to modifications and improvements in the apparatus for
making gas for which Letters Patent No. 4843, dated October 11, 1883, were granted
to me. According to my former invention a producer was constructed with its lower
part of metal, such as iron, suitably formed to receive water for cooling the metallic
walls or sides, and in conjunction therewith there was provided a revolving grate of
conical form mounted on a central stud and continuously or intermittently rotated to
clear it of ashes and clinkers. This clearing action was assisted by forming the grate
with spiral steps, perforated for the passage of air, and with curved ribs or vanes.
Now, according to the present invention, the metallic wall of the producer is made
in the form of an annular trough or box, which is kept uniformly filled with water to
a determined height, notwithstanding evaporation, by means of a ball-cock, or
equivalent device, discharging into the box, or into a cistern or vessel connected with
it. The steam which is produced by the evaporation of the water, is discharged by a
pipe or outlet into the outer air.
The revolving table is supported at or near its periphery on antifriction rollers,
instead of on a central pivot, and the blast pipe is made to discharge beneath the
centre of the table, part of the air passing through apertures in the table and the
remainder flowing round its edge, and rising through the annular space between the
table and the annular trough or box.
The lower part of the table is made without the vanes shewn in the drawings
annexed to the specification of the before-mentioned Letters Patent and the upper part
is without the steps. It may have a few vanes, however. The removal of the ashes
and clinkers is effected or assisted by a scraper or scrapers fixed to a bracket or to the
wall of the ash pit, and extending over a part of the table.

page_text: Improvements in Apparatus for Making Gas.
I, EDWARD BROOK, of Clevelands Marsh, Huddersfield, in the County of York,
Engineer, do hereby declare the nature of this invention, and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention has reference to modifications and improvements in the apparatus for
making gas for which Letters Patent No. 4843, dated October 11th 1883, were
granted to me. According to my former invention a producer was constructed with
its lower part of metal, such as iron, suitably formed to receive water for cooling the
metallic walls or sides, and in conjunction therewith there was provided a revolving
grate of conical form mounted on a central stud and continuously or intermittently
rotated to clear it of ashes and clinkers. This clearing action was assisted by forming
the grate with spiral steps, perforated for the passage of air, and with curved ribs
or vanes.
Now according to the present invention, the metallic wall of the producer is made
in the form of an annular trough or box, which is kept uniformly filled with water to
a determined height, notwithstanding evaporation, by means of a ball-cock, discharging
into the box, or into a cistern or vessel connected with it. The steam which is
produced by the evaporation of the water, is discharged by a pipe or outlet into the
outer air.
The revolving table is supported at or near its periphery on antifriction rollers,
instead of on a central pivot, and the blast pipe is made to discharge beneath the
centre of the table, part of the air passing through apertures in the table and the
remainder flowing round its edge, and rising through the annular space between the
table and the annular trough or box.
The lower part of the table is made without the vanes shewn in the drawings
annexed to the specification of the before mentioned Letters Patent and the upper part
is without the steps. It may have a few vanes, however. The removal of the ashes
and clinkers is effected or assisted by a scraper or scrapers fixed to a bracket or to the
wall of the ash pit, and extending over a part of the table.
The accompanying drawings shew an apparatus according to my invention for
making gas Fig. 1 being a vertical section, Fig. 2 a sectional plan on line A.B. of
Fig. 1, and Fig. 3 a sectional elevation of the revolving conical table with the blast or
air supply pipe.
M is the metallic wall of the producer, intended to prevent burning away of
brickwork and adhesion of clinker at this part and which to ensure its more efficient
cooling it is made in the form of an annular trough or box preferably of wrought iron,
and is kept filled with water to such a level that all portions subject to contact with
the fire shall be cooled by the water. O is an outlet through which any steam that
may be formed by the evaporation of the said water can escape. H is a small cistern
in which is an ordinary ball cock to maintain the supply of water: there is a pipe
from the cistern to the water trough W. Cis the revolving table. R. R. are anti-
friction rollers by which it is carried or supported. There may be three or more such

page_text: rollers. One of them forms part of the driving pinion. These rollers are fixed on
short shafts that work in bearings formed in the pillars N supporting the water
trough; the outer ends of the shafts may be provided with crossbars and setting-up
screws for adjusting the rollers to the table.
By supporting the revolving table C in the manner above described, the space
underneath is made available for the blast supply pipe P, whereby the air or air and
steam are conducted directly from the steam jet blower J to the underside of the
revolving table C, a portion of the blast passing through the openings XX, and the
remainder between the upper edge of a separate ring T and the revolving table, into
the ashpit E, and thence through the annular space between the underside of the water
trough W and the revolving table C. The ring T is made separate so that it may be
fixed higher or lower, and thus constitute a means of regulating the proportion of
blast admitted through the openings XX, and around the edge of the table respectively.
Any ashes that may fall down the blast pipe P can be cleaned out from time to time
through a small opening provided at the bottom.
The table C is made of a plain conical shape at its upper side. The top portion
which is secured to the bottom part by means of a few bolts is made separate for
convenience of manufacture and cheapness of renewal, and is provided with a few
curved ribs or vanes V, for assisting the descent of the ashes, which are scraped from
off the table by means of a scraper S fixed to the side of the apparatus and extending
a little distance over and up the slope of the table.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed, I declare that what I claim is :-
1. In an apparatus for making gas, making that part of the wall of the producer
chamber situate around the lower part thereof in the form of an annular metallic
trough or box such as described and illustrated and providing in connection therewith
a ball cock in connection with a water main or reservoir the arrangement, being such
as to automatically keep the said annular trough or box filled with water to a
determined height notwithstanding evaporation as above set forth.
2. In an apparatus for making gas mounting and supporting the rotatable table or
grate upon anti-friction rollers substantially in the manner described and illustrated.
3. In an apparatus for making gas the improved rotatable table or grate substantially
as described and illustrated with or without the scraper S.
4. In an apparatus for making gas the arrangement substantially as described
whereby the proportion of blast admitted respectively. through the openings of the
rotatable table or grate and around the periphery thereof respectively can be regulated
substantially as described.
5. The improved apparatus for making gas substantially as shown in and described
with reference to the annexed drawings
