PROVISIONAL SPECIFICATION.
Improvements in Coke Ovens, and in Methods of and Apparatus for
Collecting and Utilizing the Products of Combustion from such
Coke Ovens.
We ARTHUR MARSHALL CHAMBERS of Thorncliffe, Colliery Proprietor, and
THOMAS SMITH, of Chapeltown, Foreman, both in the County of York do hereby
declare the nature of our invention to be as follows:-
-
Our present invention is more especially applicable to the coke ovens and apparatus
connected therewith for which a Patent was granted to us dated June 16th A.D 1885
and numbered 7358, and it has for its objects further improvements upon such coke
ovens and apparatus connected with them, by which the quality of the coke is
improved, and it is obtained in larger pieces, and the products arising from the
coking of the coal are more thoroughly and effectively collected and utilized
In the specification and drawings of our said former Patent, we described and
shewed a pipe, preferably of fireclay or other refractory material arranged round the
upper part or cover of the oven so that it becomes sufficiently highly heated, one of
the ends of this pipe being brought forward and connected to an air supply pipe into
which air is forced at a moderate pressure, and the other end of the pipe after passing
round the oven being directed inward through the front wall of the oven and sightly
upward so that the current of heated air forced in is directed upward across the oven
At the tront of the oven below the floor is also arranged a pipe inclining downwards
and its outer end communicating with another pipe leading to a tank which com-
municates with condensing apparatus, by which the condensible oils and products are
collected and can be utilized, the gas finally passing away and being also utilized if
desired.
.
In our present invention we not only discharge the volatile and other liquids,
vapours, or gases, such as gas, tar, heavy and light hydrocarbon oils, ammoniacal
liquors, and the other well known products from the carbonization or coking of the
coal or other material, into a pipe below the floor of the oven near its front, which
pipe communicates with condensing apparatus of any of the ordinary well known
kinds in which they can be cooled and condensed and subsequently removed and
utilized; but we also make an opening at the upper part of the back of the oven,
which opening is surrounded by a straight or conical pipe of fireclay, metal lined
with fireclay, or other sufficiently refractory material which also communicates with
condensing apparatus
By this means when the current of heated air is forced into the upper part of the
coke ovens as described and shewn in the specification of our former Patent, the
products of the carbonization or coking of the coal in the oven are discharged partly
through the opening and conical pipe and to the condensing apparatus as just
described, and partly through the floor of the oven and the pipe to condensing
apparatus as first described.
By our present invention the whole of the products of combustion have not to be
forced through the coking coal, but they are partly discharged through the opening
and pipe in the top of the oven, and the quality of the coke is in this way improved
and it can be obtained in larger pieces, whilst the whole of the products of combustion
or coking are collected and utilized
In this method of coking the gases being taken partly at the bottom and partly at
the top of the oven a more uniform heat is produced throughout the whole mass of the
coal from the beginning to the end of the process, than is obtained by any other
method of coking, whilst the most inferior classes of coal and slack having any coking

page_text: qualities whatever, can be dealt with, and made into a satisfactory coke; and if the slack,
even of inferior quality be ground to the finest powder it can still be dealt with in a
satisfactory manner.

We, ARTHUR MARSHALL CHAMBERS, of Thorncliffe, Colliery Proprietor, and
THOMAS SMITH, of Chapeltown, Foreman, both in the County of York, do hereby
declare the nature of our invention and in what manner the same
performed, to be particularly described and ascertained in and by the following
statement and accompanying drawing, (that is to say)
-
Our present invention is more especially applicable to the coke ovens and apparatus
connected therewith for which a Patent was granted to us dated June 16th A.D 1885,
and numbered 7358, and it has for its objects further improvements upon such coke
ovens and apparatus connected with them, by which the quality of the coke is improved,
and it is obtained in larger pieces, and the products arising from the coking of the
coal are more thoroughly and effectually collected and utilized.
In the Specification and drawings of our said former Patent, we described and
shewed a pipe, preferably of fireclay, or other refractory material, arranged round the
upper part or crown of the oven so that it becomes sufficiently highly heated by the
heat from the latter, one of the ends of this pipe being brought forward and connected
to an air supply pipe into which air is forced at a moderate pressure, and the other
end of the pipe after passing round the oven being directed inward through the front
wall of the oven and slightly upward so that the current of heated air forced in 19
directed upwards across the oven. At the front of the oven below the floor 13 also
arranged a pipe inclining downwards and leading to condensing apparatus, by which
the condensible oils and products are collected and can be utilized, the gas finally
passing away and being also utilized if desired.
In our present invention we not only discharge the volatile and other liquids,
vapours, or gases, such as gas, tar, heavy and light hydrocarbon oils, ammoniacal liquors,
and other well known products from the carbonization or coking of the coal or other
material, into a pipe below the floor of the oven near its front, which pipe communicates
with condensing apparatus of any of the ordinary well known kinds in which they can
be cooled and condensed and subsequently removed and utilized; but we also discharge
the products of the carbonization or coking of the coal or other material through an
opening made at the upper part of the back of the oven, which opening is surrounded
by a straight or conical pipe of fireclay, metal lined with fireclay, or other sufficiently
refractory material, which also communicates with condensing apparatus
In the accompanying drawing, which is in illustration of our invention, tigure 1 is a
vertical section through an ordinary beehive shaped coke oven, and figure a plan
shewing the air pipes. a is the air supply pipe, 6 the pipe slightly inclined upward
through which heated' air is admitted into the oven, and c the pipe inclining downwards
from the front of the oven, as described and shewn in the Specification of our former
Patent already referred to.
d is the opening in the upper part of the back of the oven communicating with a
chimney and also with a pipe f which is in connection with condensing apparatus
by the pipe k.
Sliding valves or regulators are fixed in the chimney e and pipe / as shown

pipe to receive the oils and liquids is shown at h, and a pipe communicating with
condensing apparatus at?
By the novel arrangement described and shewn when the current of heated air is forced
into the upper part of the coke oven, as described and shewn in the specification of our
former Patent, the products of the carbonization or coking of the coal or other material
in the oven are discharged partly from the floor of the oven, through the pipe c (which
may also be provided with regula..ng valves) and partly through the opening
which they are conveyed to condensing apparatus, or allowed to escape into the
atmosphere through the chimney e
from
By our present invention the whole of the products of combustion have not to be
forced down through the coking coal, but they are partly discharged through the
opening d in the top of the oven, and the quality of the coke is in this way improved,
and it can be obtained in larger pieces, whilst the whole of the products of combustion
or coking are collected and can be utilized
In this method of coking according to our present invention the gases being taken
partly at the bottom, and partly at the top of the oven, a more uniform heat 19
produced throughout the whole mass of the coal, from the beginning to the end of
the process, than is obtained by any other method of coking, as by the adjustment of
the sliding valves or regulators every advantage can be taken of the more or less
rapid evolution, as well as the varying nature and value of the gases and other
products of carbonization or coking, during the process, whilst the most inferior classes
of coal and slack having any coking qualities whatever can be dealt with and made into &
satisfactory coke, and if the slack even of inferior quality be ground to the finest
powder it can still be dealt with in a satisfactory manner.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1 The combination in a coke oven of the air pipes a and b, opening d, clumney e,
and pipe f communicating with condensing apparatus, with the opening in the floor
of the oven, and pipe c communicating with condensing apparatus, substantially as
and for the purposes described and shown.
2. In combination with the opening d, chimney e, and pipe f, the regulators g g,
substantially as and for the purpose described, and shewn.
