AN IMPROVE- EN on Ten
Year: 1858

page_text: LETTERS PATENT to Edward Jones, of Dudley, in the County of
Worcester, Manager of Iron Works, for the Invention of "AN IMPROVE-
EN on Tennan
TUT
Sealed the 3rd May 1859, and dated the 1st December 1858.
PROVISIONAL SPECIFICATION left by the said Edward Jones at the
Office of the Commissioners of Patents, with his Petition, on the
1st December 1858.
I, EDWARD JONES, of Dudley, in the County of Worcester, Manager of
Iron Works, do hereby declare the nature of the said Invention for "AN
IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF COKE IN OVENS," to be
as follows:-
In coke ovens filled and worked in the ordinary manner after a sufficient
quantity of coal has been put into the oven to constitute a charge, the opening
or mouth of the oven through which it is charged is closed partially or wholly
either by a door, or by loose brickwork, and all necessary air for the com-
bustion of the coal during the process of coking is allowed to enter either
through the interstices of the brick work built up to close the mouth, or
through a brick or bricks left out for that purpose, or through flues arranged
as may be thought desirable.
My Invention consists in a construction or arrangement of flues in such a
manner as to enable me to use the waste heat given off in the process of

page_text: coking for the purpose of heating all air admitted into the oven previously to
its being so admitted. The essence of my Invention being to introduce air
heated by the waste heat of the oven into the said oven during the process of
coking in the place of cold air.
In carrying my Invention into effect, I place one or more pipes across the
chimney or flues by which the waste heat passes from the coke oven. The air
supplied to the oven passes through the said pipe or pipes, and is heated in its
passage. From the said pipe or pipes the heated air passes to the flues, by
which it is conducted to the front of the oven, and introduced into the said
oven.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Jones in the Great Seal Patent Office on the
. 28th May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
JONES, of Dudley, in the County of Worcester, Manager of Iron Works, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Edward Jones, Her special licence that I, the said Edward Jones,
my executors, administrators, and assigns, or such others as I, the said Edward
Jones, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "AN IMPROVEMENT OR IMPROVEMENTS
IN THE MANUFACTURE OF COKE IN OVENS," upon the condition (amongst others)
that I, the said Edward Jones, my executors or administrators, by an instru-
iment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office. within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Jones, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:
―
In coke ovens filled and worked in the ordinary manner after a sufficient
quantity of coal has been put into the oven to constitute a charge, the opening
or mouth of the oven through which it is charged is closed partially or wholly
either by a door or by loose brickwork, and all necessary air for the com-
bustion of the coal during the process of coking is allowed to enter either
through the interstices of the brickwork built up to close the mouth, or
through a brick or bricks left out for that purpose, or through flues arranged
as may be thought desirable.
My Invention consists in a construction or arrangement of flues in such. a
manner as to enable me to use the waste heat given off in the process of
coking for the purpose of heating all air admitted into the oven previously to
its being so admitted. The essence of my Invention being to introduce air
heated by the waste heat of the oven into the said oven during the process
of coking in the place of cold air.
I prefer to carry my Invention into effect in the manner illustrated by the
accompanying Drawing.
Figure represents in front elevation a coke oven constructed according to
my Invention; Figure 2 represents a longitudinal vertical section of the same;
and Figure 3, an end elevation of the same. Figure 4 is a transverse vertical
section; Figure 5, a horizontal section; and Figure 6, a plan of the same.
a is the oven which is charged with coal or other matter to be coked
through the mouth or opening b, which said opening b is closed after the oven
has been charged and the charge ignited. The flame and products of com-
bustion arising from the burning fuel pass through the openings c, d,. into the
flues e, f, and after pursuing the course indicated by arrows in Figure 5, pass
up through the vertical flues g, h, into the stack or chimney i. Air for the
maintenance of combustion of the burning fuel in the oven is supplied through
two pipes k, l, situated at the back of the oven. The said pipes k, l, pass
through the chimney or stack i, as shown in Figure 2. The pipe k after
traversing the chimney or stack i opens into the oven a at m, and the pipe
after rising to the top of the oven opens into the two flues n, o, which said
flues open into the oven a by an opening in the front of the said oven, which
said opening is seen at p in Figures 2 and 6. The pipes k, l, may be made of
metal coated with fire-clay, or they may be made of any other suitable material.
It is desirable that the material employed should be a tolerably good conductor
of heat. The whole of the air supplied to the oven a having to pass through
the pipes k, l, the said air is heated before it enters the said oven; the said

page_text: pipes k, l, in traversing the stack or chimney i become heated by the heated
air and products of combustion which rise up the said chimney i; q, r, are
openings in the top of the oven by which the cooling of the oven is facilitated
between the different charges, but are closed during the coking process. The
flues through which air is admitted are open at their ends, but are so arranged
that they may be closed either partially or entirely during any part of the
process of coking, as may be found desirable. A series of the coke ovens
described and represented in the accompanying Drawing may be arranged side
by side.
Although I prefer the arrangement or disposition described and represented
of the pipes or tubes k, l, in the chimney or stack of the oven, by passing
through, which said pipes or tubes the air is heated and supplied to the oven,
yet any other suitable arrangement or disposition of pipes or tubes so that they
may be heated by the waste heat from the oven, may be resorted to without
departing from the nature of my Invention.
I claim as my Invention the improvement or improvements in the manu-
facture of coke in ovens, herein-before described and illustrated in the
accompanying Drawing, that is to say, heating the air by which combustion in
the coke oven is maintained by causing the said air before it enters the
said oven to pass through pipes or flues heated by the waste heat of the coke
oven.
In witness whereof, I, the said Edward Jones, have hereunto set my
hand and seal, this Twenty-seventh day of May, in the year of our
Lord One thousand eight hundred and fifty-nine.
EDWARD JONES. (L.S.).
Witness,
JAMES TUTIN.
