An Improved Method of and Apparatus for. Producing or
Manufacturing Gas for Illuminating and other Purposes.
1, FREDERICK JOSIAH JONES, of Selly Oak House, near Birmingham, Engineer,
do hereby declare the nature of this invention to be as follows:-
:-
My Invention relates to an improved method of, and apparatus for, producing or
manufacturing gas for illuminating and other purposes, and in carrying out my
Invention 1 gasify the coal, or other gas yielding material or substance, in a chamber
distinct from, but communicating with, the combustion chamber; I collect the gas in
a chamber distinct from, but communicating with the gasifying chamber, and I then
pass the gas from the collecting chamber into and through a superheating pipe, or
superheating pipes, arranged, by preference, in the combustion chamber. By this
method I obtain a largely increased volume of gas from a given quantity of coal, &c.
by converting all, or the greater portion of the tar, and other volatile constituents
therein, into permanent gas.
My improved apparatus, or gas producer, consists of three chambers, No. 1, of
which contains the coke, &c. to be burnt, under pressure produced by a blast of air,
steam, gas, &c. No. 2, chamber contains the stratum of coal, or other material to be
gasified, and communicates with chamber No. 1, by perforations, passages, or channels
contrived in the partition wall. No. 3 is the gas collecting chamber; it communicates
with chamber No. 2, by means of perforations, passages, or channels in the partition
wall, through which the gas passes as it is generated.
The highly heated products of the combustion of the coke, &c. in No. 1 chamber,
are forced by the blast through the perforations, &c. into No. 2 chamber, where they
raise the coal to be gasified to a state of incandescence, and distil the volatile products.
The gases thus produced pass out through the other perforations into No. 3 chamber.
From No. 3 chamber, I conduct the gas, or gases, through a superheating pipe, or
pipes, arranged, by preference, in serpentine form in chamber No. 1. By this super-
heating, the greater part of the tarry, and other vapours contained in the passing
gases is converted into permanent gas, and any solid bodies or residuals which may be

page_text: formed are deposited in the said pipe, or pipes, whence they can be periodically removed.
The gas is then ready for use, but, if preferred, it may be passed through a lime, or
other purifier, to rid it from any sulphur it may contain.
And when expedient I fill, or partially fill some or all of these superheating pipes
with broken coke, limestone, coiled iron wire, or any other substance suitable for
absorbing, or having an affinity for, sulphur.
At the bottom of No. 2 chamber, I place a revolving toothed roller, or other suitable
means, for regulating the passage of the coal, &c., through the incandescent or gasing
zone, and for permitting the coke or cinders to fall out into an airtight chamber below,
from which they are removed as required, and may be used for consumption in No. 1
chamber. I provide a hopper for supplying No. 2 chamber with coal, &c. and also
means for preventing the gases rising through the hopper.
This apparatus, or producer, is chiefly intended for gasifying small non-caking coal,
but by providing outlets in No. 2 chamber, a caking coal may be used, and then coke
suitable for fuel will be obtained.

Manufacturing Gas for Illuminating and other Purposes.
I, FREDERICK JOSIAH JONES, of Selly Oak House, near Birmingham, Engineer,
do hereby declare the nature of said Invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings and to the letters and
figures marked thereon, that is to say:-
My Invention relates to an improved method of, and apparatus for, producing or
manufacturing gas for illuminating and other purposes, and will be readily understood
on reference to the accompanying drawings.
In carrying out my invention I gasify the coal, or other gas yielding material or
substance, in a chamber distinct from but communicating with the combustion chamber,
I collect the gas in a chamber distinct from but communicating with a gasifying
chamber, and then pass the gas from the collecting chamber into and through a
superheating pipe, or superheating pipes, arranged by preference in the combustion
chamber. By this method I obtain a largely increased volume of gas from a given
quantity of coal, or other gas yielding material or substance, by converting all, or the
greater portion, of the tar, and other volatile constituents therein, into permanent gas.
And in order that my Invention may be readily understood, I proceed to describe
the same with reference to the accompanying drawings in which: Figure 1 is a
transverse vertical section of my improved apparatus, or gas producer, taken on the
line a, a, of the plan fig. 5, and shewing the relative positions of the chambers.
Figure 2 is a longitudinal section, taken on the line a, b, of fig. 1, and y, y, of fig. 5.
Figure 3 is a longitudinal section, taken on the line c, d, of fig. 1, and -,, of fig. 5.
Figure 4 is a horizontal section, taken on the line e, f, of fig. 1.
In all the figures like letters of reference indicate similar parts.
My improved apparatus, or gas producer, which is built up of fire brick and iron
work, consists of three chambers A, B, C, the chamber A, of which contains the coke,
or other material or substance, to be burnt, and which is burnt under pressure produced
by a blast of air, steam, or gas, introduced through the pipe p, arranged below the
fire bars, as seen in fig. 2. This chamber is provided with a charging hole A¹.
The chamber B contains the stratum of coal, or other gas yielding material, to be
gasified, and communicates with the chamber A, by perforations, passages, or channels g,
contrived in the partition wall.
The chamber is the gas collecting chamber; it communicates with the gasifying
chamber B, by means of perforations, passages, or channels h, in the partition wall,
through which the gas, as generated, passes.
The highly heated products of the combustion of the coke, or other material or
substance, in chamber A, are forced by the blast through the perforations g, into the
gasifying chamber B, where they raise the coal, or other material, to be gasified, to a
state of incandescence and distil the volatile products. The gases thus produced pass
out through the perforations, passages, or channels h, into the collecting chamber C.

page_text: From this chamber C, I conduct the gas or gases through a superheating pipe or
pipes D, arranged by preference in serpentine form in the chamber A. By this super-
heating the greater part of the tarry and other vapours contained in the passing gases,
is converted into permanent gas, and any solid bodies or residuals which may be
formed, are deposited in the said pipe or pipes, whence they can be periodically removed
through the cleaning holes i, which are closed by the covers i*. The gas is then ready
for use, but if preferred, it may be passed through a lime, or other purifier, not shewn
in the drawings, to rid it from any sulphur, or other impurities, it may contain.
And when expedient I fill, or partially fill some, or all, of the superheating pipe
or pipes D, with broken coke, limestone, iron horings, coiled iron wire, or any suitable
substance to increase the heating surface and to arrest some of the impurities contained
in the passing gases.
At the bottom of the chamber B, I place a revolving toothed roller E, driven at a
suitable speed by pulleys and straps, for regulating the passage of the coal, or other
gas yielding material, through the incandescent or gassing zone, and for permitting the
coke or cinders to fall out into an air tight chamber G below said roller, from which
they are removed, as required, and may be used for consumption in chamber A. But
instead of the toothed roller E, any other suitable means may be employed for the
purpose.
I further provide a hopper H, for supplying the gasifying chamber B with coal, or
other gas yielding material, and beneath this hopper I arrange a perforated sliding
plate J, which can be moved backwards and forwards, over a fixed perforated plate,
by means of a screw and wheel or pulley Jx, thus opening or closing the hopper, and
when closed preventing the gases rising through the hopper.
This apparatus, or producor, is chiefly intended for gasifying small non caking coal,
but by providing outlets in chamber B a caking coal may be used.
Having now described and ascertained the nature of my Invention and in what
manner the same may be performed, I claim :-
--
First. The herein described method of producing or manufacturing gas for illumin-
ating, and other, purposes, consisting in gasifying the coal, or other gas yielding
material, in a chamber distinct from but communicating with the combustion chamber,
collecting the gas in a chamber distinct, from, but communicating with the gasifying
chamber, and then passing the gas through a superheating pipe, or pipes, arranged, by
preference, in the combustion chamber, substantially as specified.
Second. The improved apparatus, or gas producer, consisting of a combustion
chamber, a gasifying chamber, and a gas collecting chamber, separated from each other
by partition walls, the said gasifying chamber communicating, on the one hand, with
the combustion chamber by means of perforations, passages, or channels, in one of the
partition wa Is, through which the highly heated products of combustion are forced,
and on the other hand with the gas collecting chamber, by means also of perforations,
passages, or channels in the other of the partition walls, through which the gas, as
generated, passes; a pipe or pipes leading from the gas collecting chamber and
circulating in the combustion chamber, for the purpose of superheating the gas, and
means for regulating the inlet and descent of the material to be gasified, and permitting
the passage and outlet of the coke and cinders, all substantially as herein described
and as shewn in the drawings.
