IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF COKE OVENS AND OF SALT EVAPORATING PANS HEATED THEREFROM
Year: 1873

page_text: LETTERS PATENT to Peter Jensen, of 89, Chancery Lane, in the
County of Middlesex, Engineer and Patent Agent, for the Inven-
tion of "IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF COKE
OVENS AND OF SALT EVAPORATING PANS HEATED THEREFROM."-A com-
munication from abroad by Egmond Julius Erichsen and Jörgen
Georg Maardt, both of Copenhagen, in the Kingdom of Denmark.
Sealed the 19th September 1873, and dated the 22nd March 1873.
PROVISIONAL SPECIFICATION left by the said Peter Jensen at the
Office of the Commissioners of Patents, with his Petition, on the
22nd March 1873.
I, PETER JENSEN, of 89, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGEMENT OF
COKE OVENS AND OF SALT EVAPORATING PANS HEATED THEREFROM," (a com-
munication to me from abroad by Egmond Julius Erichsen and Jörgen

page_text: Georg Maardt, both of Copenhagen, in the Kingdom of Denmark,) to
be as follows:-
The object of this Invention is to utilize the waste heat proceeding
from a series of two or more coke ovens to the heating of salt evaporating
pans. For this purpose the salt pan is placed partly or wholly over the
coke ovens, in the latter case the pan bottom forms the roof of the coke
ovens. The heated products of combustion on leaving the coke ovens
enter into a flue or flues passing under the pan bottom and into another
flue or flues passing through the salt pan. By means of dampers one or
the other set of flues may be partially or wholly shut-off as required. 1
The necessary air for the further or complete combustion is admitted in
regulated quantity into the flues. There are other flues with dampers
for leading the products of combustion into the chimney flue directly
instead of into the salt pan heating flues when required.
The coking
process as well as the evaporating process may thus be carried on
efficiently and to a great extent independently of one another, and perfect
control of the heat obtained without loss of time.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Jensen in the Great Seal Patent Office on
the 22nd September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PETER
JENSEN, of 89, Chancery Lane, in the County of Middlesex, Engineer
and Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of March, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Peter Jensen, Her special licence that I, the
said Peter Jensen, my executors, administrators, and assigns, or such
others as I, the said Peter Jensen, 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, excrcise, and vend, within the United

Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN THE CONSTRUCTION AND ARRANGE-
MENT OF COKE OVENS AND OF SALT EVAPORATING PANS HEATED THEREPROM," (a
communication to me from abroad by Egmond Julius Erichsen and
Jörgen Georg Maardt, both of Copenhagen, in the Kingdom of
Denmark,) upon the condition (amongst others) that I, the said Peter
Jensen, my executors or adminisstrators, 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Peter Jensen, 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, that is to say :-
The object of this Invention is to utilize the waste heat proceeding
from a series of two or more coke ovens to the heating of salt evaporating
pans. For this purpose the salt pan is placed partly or wholly over the
coke ovens, in the latter case the pan bottom forms the roof of the coke
ovens. The heated products of combustion on leaving the coke ovens
enter into a flue or flues passing under the pan bottom and into another
flue or flues passing through the salt pan. By means of dampers
one or the other set of flues may be partially or wholly shut-off as
required. The necessary air for the further or complete combustion is
admitted in regulated quantity into the flues. There are other flues
with dampers for leading the products of combustion into the chimney
flue directly instead of into the salt pan heating flues when required. The
coking process as well as the evaporating process may thus be carried on
efficiently and to a great extent independently of one another, and
perfect control of the heat obtained without loss of time.
And having now described the nature of this Invention I declare that
I claim, not simply the utilization of the waste heat proceeding from
two or more coke ovens to the heating of a salt evaporating pan, but I
do claim the mode or modes herein described in which the heat is
sustained and utilized in an efficient manner, and perfect control is

page_text: obtained as required, both for the coking and for the salt evaporating
process.
In witness whereof, I, the said Peter Jensen, have hereunto set my
hand and seal, this Twenty-second day of September, in the
year of our Lord One thousand eight hundred and seventy- &
three.
