PROVISIONAL SPECIFICATION.
An Improved Apparatus for the Manufacture of Gas for Lighting and
Heating, and for use in Gas Engines.
I HENRY JOHN ROGERS of Lavington House Watford in the County of
Hertford Engineer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct a gas producer in a more concentrated
form than has hitherto been the practice and thus to simplify the process of gas-
making and to lessen the cost of the apparatus used therefor.
I construct my producer with an outer shell of iron or other suitable material
lined on the inside with ganister or fire clay and having for its base an ashpit with
a door that can be hermetically sealed; the grate bars are cast in one or more
pieces and have spaces around the sides corresponding with projections in the
framework of the said ashpit and when it is required to fix the said bars in position
the spaces are placed opposite the said projections and the bars raised and they are
then turned round so that the solid part of the frame rests upon the said projections:
above the said bars is a liner of firebrick or other refractory material in which the
coal or coke used for producing gas is placed and around this said line and
extending above it to the top of the producer is a coil of pipes, the lower part of
which contains water and the upper part steam which is superheated as it passes
through the topmost coils, the steam is then led from these coils through the ashpit
and under the grate bars by means of an injector, the said injector drawing in
atmospheric air and forcing both air and steam through the incandescent fuel in the
producer.
If it is desired to produce illuminating gas, oil may be also injected with the air
and steam.
The usual arrangements are provided at the top of the producer for admitting
the fuel, for the exit of the products of combustion when gas is not being produced
and for the passage of gas to the condenser.
I construct the condenser in a more concentrated form by passing the
gas through
a pipe immersed in a column of feed water the water cooling the gas on its way to
the gasholder and the gas in its turn heating the water on its way to the coil inside
the producer.
The coil is provided with the usual steam gauge, safety valve and water gauges.
The air may be warmed before injection by passing it through a coil in the
ashpit or other suitable locality.

COMPLETE SPECIFICATION.
An Improved Apparatus for the Manufacture of Gas for Lighting and
Heating, and for use in Gas Engines.
I, HENRY JOHN ROGERS of "Lavington" Watford in the County of Hertford,
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 :―
The object of this invention is to construct a gas producer in a more concentrated
form than has been hitherto the practice, and thus to simplify the process of gas
making, and to lessen the cost of the apparatus used therefor.

page_text: I construct my producer with an outer shell of iron a a Figs. 1. 2. 3. 4 lined on
the inside with fire clay, ganister or other refractory material and having for its
base an ash pit c with a door d that can be hermetically sealed; the grate bars e
are cast in one or more pieces and can be hung upon bearers fin any convenient
manner.
Embedded in the above described lining of refractory material is a coil g or coils
of pipes Fig. 1 the lower part of which contains water & the upper part steam, or
in the case of more than one coil steam is generated in one coil & superheated in
another, and I prefer to fix a steam chamber h between the water and steam coils.
The steam is led from these coils through the ash pit and under the grate bars by
means of an injector which draws in atmospheric air, and forces both air and
steam through the incandescent fuel in the producer.
If it is desired to produce illuminating gas, oil may be also injected with the air
and steam from the tank Fig. 3.
The usual arrangements; Figs. 1 and 2 are provided at the top of the producer
for admitting the fuel, for the exit k of the products of combustion when gas is not
being produced and for the passage 7 of gas to the condenser.
I also in some cases dispense with one of the coils and substitute a tubular or
other boiler m Fig. 3 and 4 above the refractory material in the producer and lead
the steam therefrom to a coil n imbedded in the said refractory material for the
purpose of superheating it before passing it through the injector to the incandescent
fuel and in order that the boiler m may be easily removed when required I
construct a lute on the outside of the casing a & a corresponding projection on
the angle flange p of the boiler m & fill the said lute with asbestos or other suitable
material for making a joint.
I construct the condenser q (see Figs. 1. 2 and 4) also in a more concentrated
form by passing the gas through a pipe immersed in a column of feed water, the
water cooling the gas on its way to the gas holder and the gas, in its turn, heating
the water on its way to the coil or boiler inside the producer.
The coil or boiler is provided with the usual steam gauge, safety valve, & water
gauges.
The air may be warmed before injection by passing it through a coil w see
Figs. 1 and 4 in the ashpit or other suitable locality and the oil may be vaporized
before passing it through the injector.
I prefer to clinker the furnace bars e without opening the furnace door d and I
effect this by means of a handle r, see Fig. 1, working in a slot in a lever u pivotted
on a fulcrum the long arms w of the lever passing through the fire bars e and thus
clearing the clinkers away between the bars there being as many arms was spaces
between the bars. The feed valve s Figs. 3 and 4 is so arranged that by removing
the loose covert the state of the fire can be seen below and if necessary the fire
can be clinkered with a long bar through the same hole which serves the double
purpose of a sight hole and clinkering hole.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
First The apparatus for the concentration of the processes of generating gas
and steam
Second The apparatus for heating the feed water and cooling the gases
Third The arrangement for clinkering the firebars without opening the furnace
door and
Fourth The arrangement of feed valve and sight hole and clinkering hole
combined.
