We JAMES ALFRED WANKLYN 6 Derby Villas New Malden Surrey, Professor
of Chemistry WILLIAM JOHN COOPER 6 Derby Villas New Malden Surrey
Consulting and Analytical Chemist do hereby declare the nature of this invention to
be as follows:-
We first make an artificial cannel by causing wood-charcoal (conveniently got
from wood heated in a gas-retort), or other suitable porous material to absorb either
American petroleum, or Russian kerosene, or crude Russian petroleum, or the
astatki, or other suitable mineral oil from other countries or other cheap refuse
carbonaceous liquids including gas-tar. Having made our artificial cannel we
employ it in gas works by carbonizing it very much in the usual manner with
mechanical device to secure proper heating-either a through retort with one
ascension pipe blocked up or else an internal tube to contain the cannel. The wood
charcoal may be used over & over again to regenerate the artificial cannel by being
made to absorb fresh petroleum. Great economy arises from using the charcoal
over again & the charcoal may sometimes absorb water to form water-gas for the
dilution of the gas.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Gas for Heating and
Illumination.
JAMES ALFRED WANKLYN of 6 Derby Villas New Malden Surrey, Professor
of Chemistry and WILLIAM JOHN COOPER of 6 Derby Villas New Malden
Surrey Consulting and Analytical Chemist, 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 :-
Our improvements in the manufacture of gas for heating and illumination are
described as follows:-
In carrying out our invention we make an artificial material the equivalent of
ordinary cannel coal by bringing wood charcoal into contact with American
petroleum or Russian kerosene or crude Russian petroleum or astatki or other like
suitable mineral oils from other countries or other cheap carbonaceous liquids,
including gas tar. The kind of charcoal which we find may be used with advantage
is that which has been produced by carbonizing wood such as ordinary pine or other
ordinary woods at almost the lowest temperature, at which the carbonization can be
effected.
We immerse the charcoal so prepared in the mineral oil intended to be absorbed
and find that such charcoal is capable of absorbing the mineral oils with great ease
and in very large proportions in some cases as much oil as is equivalent to three
times the weight of the absorbing material is taken up.

page_text: Having made the artificial cannel we employ it for the production of gas for
heating and illumination. This we do by heating it in a separate gas-retort in the
same manner as ordinary cannel is treated in gas works. We find it advantageous
however (owing to the fragile character of our artificial cannel which will not bear
rough handling) to place it in any convenient iron receptacle such as a length of
stove piping. The iron receptacle charged with the artificial cannel is then put
into the gas retort and then subjected to the usual heating process and gas of the
required character is thereby produced in the well known manner. Afterwards
the iron receptacle which now holds residual charcoal is drawn out of the retort,
cooled in the well known manner and then mineral oil of the required character is
poured upon the residual charcoal which absorbs it or the residual charcoal is
immersed in the oil and thus by repeating the operations above described a cannel
suitable for employment for gas-making is produced in a very economical and
efficient manner as before.
Instead of an iron receptacle it may in some cases be advantageous to use a
receptacle made of the compact charcoal obtained by heating wood to a very high
temperature or receptacles made of other refractory materials may be used.
Properly prepared charcoal may be used very many times in repeated operations
such as are above described. It takes up mineral oil evolves gas in the gas-retort
and will then again absorb a fresh supply of mineral oil and so reproduce the
artificial cannel.
Having now particularly described and ascertained the nature of our said inven-
tion and the manner in which it is to be performed we declare that what we
claim is.
(1) The manufacture of artificial cannel substantially as described.
(2) The production of gas of a character like ordinary cannel gas substantially
as described.
(3) The manufacture of regenerated or renovated artificial cannel substantially
as described.
