Improvements in Coke Ovens, and in the Method of Removing and
Utilizing the Products of Combustion from such Coke Ovens.
We, HOWARD ASTON ALLPORT, of Dodworth Grove, near Barnsley, in the
County of York, Colliery Proprietor, and ATKINSON CROSSLEY, of The Scarlet
Ferric Oxide Company, Talywain, near Pontypool, in the County of Monmouth,
Manufacturing Chemist, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to the ovens ordinarily used for coking coal, and for
removing and utilizing the products obtained in such coking, such as gas, tar,
hydrocarbon oils, ammoniacal liquor, and the like.
We are aware that it has been proposed to withdraw the different products of
combustion evolved by the coal in coke ovens, during the process of coking, by
making openings or perforations in the floor of the coke oven, upon which the coal
rests, and withdrawing the products of combustion through such openings or
perforations by means of exhausting fans, chimneys, or equivalent means, the gas
and other substances so withdrawn being treated in condensers and apparatus of
the well-known kinds for the purpose of separating, purifying, and utilizing the
various substances present. We are also well aware that instead of using
exhausting apparatus in the way just described for the purpose of withdrawing
the products of combustion through the floor of coke ovens, such products have
been driven out by the pressure of air, preferably heated, forced into the oven
above the coal which is being coked, as described and illustrated, for instance, in
the Specification of Letters Patent granted to Arthur Marshall Chambers and
Thomas Smith, dated March 11th, A.D. 1884, and numbered 4,708, of Letters
Patent granted to the said Arthur Marshall Chambers and Thomas Smith, dated
June 16th A.D. 1885, and numbered 7,358, and of Letters Patent granted to the
said Arthur Marshall Chambers and Thomas Smith, dated May 3rd, A.D. 1889,
and numbered 7424.
Our present invention consists essentially in using simultaneously both the
operations or processes above described, for the purpose of withdrawing and
utilizing the products of combustion from coal being coked in ovens, that is to say,
that of withdrawing such products by exhausting apparatus and' of expelling them
by means of air forced in above the coal. By this means we are enabled to obtain
and utilize the products of combustion without affecting the quantity or quality of
the coke produced, and we are also enabled to use without disadvantage small or
inferior coal.
In order to put our invention in operation, therefore, we use coke ovens having
openings or perforations in the bottom, upon which the coal is supported, and we
withdraw the products of combustion through these openings or perforations by
means of exhausting fans or apparatus, or by one or more chimneys, the said
products of combustion' being treated in the well-known way to extract from them
the valuable substances contained in them, in the manner described in the Specifi-
cations of A. M. Chambers and T. Smith already above referred to, or in an
equivalent mauner, but simultaneously with the exhausting process we force air
into the upper part of the oven above the coal, so that the products of combustion
are forced down in addition to being drawn' out by exhaustion.

page_text: We do not confine ourselves to any particular form or details of apparatus, which
may be varied more or less as may be found advisable.

claim is :-
For the purpose of withdrawing the products of combustion from coal being
coked in ovens, the combination of the process of withdrawing such products by
exhausting apparatus, with the process of expelling them by means of air forced
into the oven above the coal, substantially as described.
