Year: 1858

page_text: LETTERS PATENT to John James Russell, of Wednesbury, in the County
of Stafford, Iron Tube Manufacturer, for the Invention of "IMPROVEMENTS
IN FURNACES FOR HEATING IRON AND STEEL, SUITABLE FOR THE MANUFACTURE
OF WELDED TUBES AND OTHER ARTICLES."
Sealed the 25th November 1858, and dated the 30th September 1858.
PROVISIONAL SPECIFICATION left by the said John James Russell at
the Office of the Commissioners of Patents, with his Petition, on
the 30th September 1858.
I, JOHN JAMES RUSSELL, of Wednesbury, in the County of Stafford, Iron
Tube Manufacturer, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN FURNACES FOR HEATING IRON AND STEEL, SUITABLE FOR THE
MANUFACTURE OF WELDED TUBES AND OTHER ARTICLES," to be as follows:-
This Invention has for its object improvements in furnaces for heating iron
and steel suitable for the manufacture of welded tubes and other articles.
For these purposes each furnace is made, by preference, with several fire-
places at one end, which are separated or divided from the body of the
reverberatory furnace by a bridge. The body of the furnace is divided into
two working compartments, which have each a working door; the working
door of one working compartment is on the opposite side of the furnace to the

page_text: working door of the other working compartment. The bed of each working
compartment is inclined in a direction from the working door towards the
opposite side of the furnace, so that the bed is highest at the door, and the
two working compartments are separated by a bridge or partition which is
constructed in an inclined direction-across the furnace from side to side, so
that each of the two beds of the working compartments of the furnace is
wider at the end where the working door is situated, than it is at the further
end.
At the back end of the furnace is formed a hollow bridge, over and under
which the flames pass from the fire-places and the body of the furnace to the
chimney. This hollow bridge forms an oven from side to side of the furnace,
for the introduction of the iron or steel, in order to the same being pre-
paratorily heated.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John James Russell in the Great Seal Patent Office on the
29th March 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JAMES RUSSELL, of Wednesbury, in the County of Stafford, Iron Tubė
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, 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 John James Russell, Her special licence that I, the said John
James Russell, my executors, administrators, and assigns, or such others as
I, the said John James Russell, 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 "IMPROVEMENTS IN FURNACES FOR HEATING IRON AND STEEL, SUITABLE FOR
THE MANUFACTURE OF WELDED TUBES AND OTHER ARTICLES," upon the condition
(amongst others) that I, the said John James Russell, 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

page_text: 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 John James Russell, 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 follow-
ing statement thereof, that is to say:-
This Invention has for its object improvements in furnaces for heating iron
and steel, suitable for the manufacture of welded tubes and other articles.
For these purposes each furnace is made by preference with several fire-places
at one end, which are separated or divided from the body of the reverberatory
furnace by a bridge. The body of the furnace is divided into two working
compartments, which have each a working door. The working door of one
working compartment is on the opposite side of the furnace to the working
door of the other working compartment. The bed of each working com-
partment is inclined in a direction from the working door towards the opposite
side of the furnace, so that the bed is highest at the door, and the two working
compartments are separated by a bridge or partition which is constructed in
an inclined direction across the furnace from side to side, so that each of the
two beds of the working compartments of the furnace is wider at the end
where the working door is situated than it is at the further end. At the back
end of the furnace is formed a hollow bridge, over and under which, the
flames pass from the fire-places and the body of the furnace to the chimney.
This hollow bridge forms an oven from side to side of the furnace for the
introduction of the iron or steel in order to the same being preparatorily
heated.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 is a plan of a furnace, in section, constructed according to my
Invention; Figure 2 shows a section taken as indicated by the lines E, E;
and Figures 8 and 4 show the two end views of the furnace. The furnace
shewn is arranged to have four fire-places, but this may be varied. The
furnace is constructed with two working floors or beds A and B, and they incline
in opposite directions, and they have their doors at the opposite ends of the
combined furnaces, as shown by the Drawing; C is an oven in which iron or
steel is preparatorily heated, which, however, may be dispensed with, and an

page_text: ordinary bridge constructed. What I claim is, the combination of two
furnaces or working compartments as herein described.
In witness whereof, I, the said John James Russell, have hereunto set
my hand and seal, this Twenty-sixth day of March, in the year of
our Lord One thousand eight hundred and fifty-nine.
Witness,
JNO. ALCOCK.
