Year: 1859

page_text: LETTERS PATENT to Edward Jones, of the Russell's Hall Iron Works,
Dudley, in the County of Worcester, Furnace Manager, for the Invention
of "AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF COKE IN
OPEN COKE FIRES OR HEAPS."
Sealed the 17th February 1860, and dated the 22nd September 1859.
PROVISIONAL SPECIFICATION left by the said Edward Jones at the
Office of the Commissioners of Patents, with his Petition, on the
22nd September 1859.
I, EDWARD JONES, of the Russell's Hall Iron Works, Dudley, in the County
of Worcester, Furnace Manager, do hereby declare the nature of the said
Invention for "AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF COKE
IN OPEN COKE FIRES OR HEAPS," to be as follows:-
My improvement or improvements in the manufacture of coke in open coke
fires or heaps, consist in collecting the tar and other condensable products given
off in the process of coking, and which products are now either wholly or
partially dissipated or lost, and I effect the same by combining with the chim-
ney or chimneys now ordinarily made use of in open coke fires or heaps, one
or more flues so arranged as to collect and condense such of the products as
are capable of condensation, and convey them into suitable tanks or condensers
or other receivers. I sometimes assist the action of such flue or flues by closing

page_text: the top of the chimney or chimneys of the coke heap with suitable coverings
or with coke or mine dust or other loose material; I also, if necessary, connect
the said flue or flues with a separate chimney or stack, by which the draught
can be increased or regulated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Jones in the Great Seal Patent Office on the 17th
March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
JONES, of the Russell's Hall Iron Works, Dudley, in the County of Worcester,
Furnace Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of September, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third 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 OPEN COKE FIRES OR HEAPS,"
upon the condition (amongst others) that I, the said Edward Jones, my
executors or administrators, by an instrument 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 immediately 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 performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
In the ordinary process of coking in open fires or heaps, the coal to be
coked is arranged in heaps or moulds of various sizes and forms, and the
draught of air into or through such fire or heap, is generally regulated by

page_text: means of one or more chimneys or stacks placed within the coke fire or heap,
or in immediate connection with it, and either before the coke fire or heap is
ignited,
or during the process of its burning, the said coke heap is generally
covered with coke or mine dust or some other powdered solid to assist in regu-
lating or checking the draught of air into it, or to protect it from the excessive
or injurious action of the atmosphere. In the ordinary process of coking, as
described, the tar or other condensable volatile products formed during the
coking are given off into the atmosphere and lost.
My improvement or improvements in the manufacture of coke in open coke
fires or heaps, consist in collecting and condensing the tar or other condensable
volatile products given off in the process of coking, instead of allowing the said
products to be lost by escaping into the air.

In carrying my Invention into effect, I connect .the chimney or chimneys
ordinarily made use of in open coke fires or heaps, with a flue communicating
with a pipe or series of pipes so arranged that the tar or other condensable
volatile products given off during the process of coking, shall wholly or mainly
pass into and along the said pipe or series of pipes, and in such passage
condensed either wholly or mainly. Or the said volatile products may
conducted to condensers especially adapted to their condensation; such, for
example, as the condensers employed for like purposes in the manufacture of
gas for illumination. The said tar or other volatile products having been con-
densed in either of the ways described, they may be either collected or stored
in the condensers themselves or be allowed to run from the said condensers
into suitable receptacles.
To facilitate the collecting and condensing of the condensable volatile products
I prefer to close the chimney or chimneys of the coke heap at their tops before
or soon after igniting the heap by means of an iron or other plate or damper,
or in any other convenient manner, so as to control the draught required for
combustion or produced by the said combustion and prevent it from passing
through the said chimney or chimneys into the open air, and thereby carrying
off the volatile condensable products. To promote the passage of the con-
densable volatile products into and through the pipe or pipes leading from the
chimney or chimneys in which the said volatile products are condensed, I
connect the said pipe or pipes with a main chimney or stack of any requisite
height or I connect the said pipe or pipes with a main flue, the said main flue
opening into the said chimney or stack, I also usually cover the coke heap either
wholly or partially with coke or mine dust or other powdered solid, or instead
of powdered coke or other solid, I sometimes use a covering either of metal or
other material, for the purpose of regulating the draught or for protecting the

page_text: coke heap from the excessive action of the air, or for assisting in collecting the
condensable volatile products given off by the said coke heap. I sometimes
connect the pipe or pipes into which the volatile products pass with an exhauster
or exhausters by which the said products can be drawn off or forced into any
suitable flue or channel, or into any suitable receiver or receivers, and I
either use the exhauster without a main chimney or stack, or in combination
with one as may be found most convenient.
Although I prefer the arrangement or arrangements herein-before described,
yet I do not confine myself thereto exclusively, or to any one of them, but I
wish it to be understood that any other suitable arrangement may be used by
which the condensable volatile products may be collected and condensed from
open coke fires or heaps.
Although I have described the use of a pipe or pipes through which the
volatile products are made to pass, and in which they are condensed, and which
said pipes I prefer to make of metal, yet a flue or flues or channels of brick or
masonry may be employed for that purpose, with the same or nearly the same
effect.
I claim as my Invention the improvement or improvements in the
manufacture of coke in open coke fires or heaps herein-before described, that
is to say, collecting and condensing from the said open coke fires or heaps,
either mainly or wholly the tar or other condensable volatile products given off
during the coking process.
In witness whereof, I, the said Edward Jones, have hereunto set my
hand and seal, this Sixteenth day of March, in the year of our Lord
One thousand eight hundred and sixty.
EDWARD JONES.
