Improvements Connected with the Manufacture of Water Gas and
other Gases for Lighting, Heating, and Manufacturing Purposes,
and in Apparatus therefor.
I SAMUEL LEVY, of Bevis Marks, City of London, Merchant do hereby declare
the nature of this invention to be as follows:-
The object of this invention is to construct and arrange furnaces for the manu-
facture of water and other gas composed of a combination of hydrogen gas produced
from the decomposition of superheated steam together with carbonic acid gas or
carbonous oxide or its gas and gas produced from coal oil or Hydrocarbon gas
generated from Petroleum or any of its products by distillation and decomposition by
intense heat so as to fix the same as a permanent gas.
This invention is also designed to render such furnaces capable of being used
economically for the production of Carbonic Oxide Gas alone if desired or in
combination with gas produced from oil as well as for the combination of Hydrogen,
Carbonic Acid and Oil Gases as before mentioned.
The furnace is constructed in three main parts one of which is for Generating
another for Superheating and another is termed the Fixing chamber, these having the
necessary connections with flues, valves &c. to admit of the Gases being generated
and then fixed in regular sequence with as small an amount of manual labour as
possible.
The gas
which is formed in the generating chamber is met at the upper part by a
spray of Hydrocarbon oil, or oil vapour and they together pass through a pipe into
the Fixing chamber where they become a fixed gas conductible from thence to a
holder to be stored for use.
Should carbonous oxide gas be required air is admitted in suitable proportions
instead of steam.

Improvements Connected with the Manufacture of Water Gas and
other Gases for Lighting, Heating, and Manufacturing Purposes,
and in Apparatus therefor.
I, SAMUEL LEVY of Bevis Marks, City of London, Merchant, do hereby declare
the nature of this invention, which has been communicated to me from abroad by
George H. Kohn of Denver, Colorado, United States of America, Attorney, 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 and arrange furnaces for the manu-
facture of water and other gas composed of a combination of hydrogen gas produced
from the decomposition of superheated steam together with carbonic acid gas or
carbonous oxide or its gas, and gas produced from coal oil or hydro-carbon, gas
generated from petroleum or any of its products by distillation and decomposition by
intense heat so as to fix the same as a permanent gas.
This invention is also designed to render such furnaces capable of being used
economically for the production of carbonous oxide gas alone if desired, or in
combination with gas produced from oil as well as for the combination of hydrogen,
carbonous acid and oil gases as before mentioned.
The furnace is constructed in three main parts, one of which is for generating,
another for superheating, and another is termed the fixing chamber, these having the
necessary connections with flues, valves, etc. to admit of the gases being generated
and then fixed in regular sequence with as small an amount of manual labour as
possible.
The gas
which is formed in the generating chamber is met at the upper part by a
spray of hydro-carbon oil or oil vapour and they together pass through a pipe into the
fixing chamber, where they become a fixed gas conductible from thence to a holder to
be stored for use.
Should carbonous oxide gas be required, air is admitted in suitable proportions
instead of steam.
The operation for making water gas, as herein before mentioned, will be understood
by reference to the annexed drawings Figures 1, 2, 3, 4, 5, and 6.
Supposing the valve B to be open, a fire is started on grate P. When fairly lighted
An air blast
all doors and openings in the furnace are closed except valve B.
through Z is turned on at 2. Valves E and I are opened and the caps removed
from J and J. When the fuel becomes incandescent valve B is closed and the gas
issuing from the generator X through the passages El and I into superheater R and
fixing chamber Y is there met by a second blast of air introduced through nozzles S
and Sand pipe T whereby it is burned, producing a high degree of heat.
The intensely heated products of this combustion passes on through chambers R
and Y yielding up on the way most of its heat to the fire brick with which these

page_text: chambers are filled and passing out at last in a comparatively cool condition at the
openings J and J, the caps of which are removed. When this operation has been
continued for a sufficient length of time so that the fire brick in chambers R and Y
have attained an intense heat, valve Z is closed, thus shutting off the blast of air
from the furnace chamber X.
The valve in pipe leading to nozzles S and S¹ is closed, thus shutting the air off
from chambers R and Y. Valve E is now closed and valve G opened. A jet of
steam is introduced through pipes S2 and passage T into chamber R where in passing
through the fire brick it becomes intensely superheated and in this condition enters
at the bottom of the generator through passage G', the valve G having been opened.
It then passes up through the now incandescent fuel in X and is decomposed with the
formation of carbonous oxide and free hydrogen, the mixture of these two gases with
such volatile hydro-carbons as the fuel may furnish, now issues from the top of the
fuel in the generator and constitutes the water gas. The water gas thus formed is
met by a spray of hydro-carbon oil, oil vapour, introduced at K and together they
pass through valve I to chamber Y, where they become a fixed gas, which is conducted
thence by the pipe L to the purifying apparatus M. and thence to the holder where it
is stored for use.
By reference to the parts and the description given above it will be seen that the
product of the combustion of the air can be completely excluded from the water gas
with but a limited loss of the latter by leaving one or both caps J off for a few
moments after the steam has been introduced at $2 or until the products of the
combustion of the air has been swept off at J and the water gas makes its appearance
at that part.
In the foregoing operation hydrogen gas is used for volume. Should it be deemed
advisable to use carbonous oxide gas, the steam at S is cut off and air only is
introduced at S¹, the operation in other respects being precisely the same as when
steam is used.
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. The manufacture of water gas for lighting and heating purposes in the manner
set forth.
2. The particular combination and arrangement of apparatus shown on the annexed
drawings, i.e. three distinct vessels but so connected and provided with valves that
the operation or manufacture of water gas can be carried into practical effect as
described.
