A NEW OR IMPROVED CUPELO
Year: 1853

page_text: LETTERS PATENT to Joseph Spencer, of Bilston, in the County of
Stafford, Iron Founder and Engineer, for the Invention of "A
NEW OR IMPROVED CUPELO."
ealed the 7th December 1853, and dated the 13th June 185
PROVISIONAL SPECIFICATION left by the said Joseph Spencer at
the Office of the Commissioners of Patents, with his Petition,
on the 13th June 1853.
I, JOSEPH SPENCER, of Bilston, in the County of Stafford, Iron Founder
and Engineer, do hereby declare the nature of the said Invention for
"A NEW OR IMPROVED CUPELO" to be as follows:-
My Invention consists in adding to the ordinary cupelo used for
melting cast iron a second cupelo or reservoir for containing an addi-
tional quantity of iron, the said second cupelo or reservoir being so
connected with the first that the fused iron therein may be drawn
off from the tap hole of the first.
The said second cupelo or reservoir may, however, be used by itself;
that is to say, the iron contained in it may be drawn off when required
from its own tap hole; the essence of my Invention consisting in so

page_text: arranging two cupelos or a cupelo and reservoir, side by side, that the
contents of the two cupelos may either be drawn off' singly, or both
from one tap hole, or the contents of the reservoir and cupelo drawn
off at the tap hole of the said cupelo where a larger quantity of iron is
required than can be contained in one cupelo.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Spencer in the Great Seal Patent Office,
on the 10th December 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOSEPH SPENCER, of Bilston, in the County of Stafford, Iron Founder
and Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of June, in the year
of our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Joseph Spencer, Her special licence
that I, the said Joseph Spencer, my executors, alministrators, and as-
signs, or such others as I, the said Joseph Spencer, 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 "A NEW OR
IMPROVED CUPELO," upon the condition (amongst others) that 1, the said
Joseph Spencer, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 calen-
dar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Joseph Spencer, do hereby de-
clare 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):

page_text: My Invention consists in making the cupelo used for fusing cast
iron double; that is to say, in adding to the ordinary cupelo a second
cupelo or reservoir for containing an additional quantity of iron, the
said reservoir or second cupelo being so connected with the first that
the fused iron in the said second cupelo may be drawn off from the tap
hole of the first. The said reservoir or second cupelo may, however,
be so arranged that it may be used by itself; that is to say, the iron
contained in it may be drawn off when required from its own tap hole.
I do not think it necessary to describe the various manners in which
two cupelos or a cupelo and reservoir may be combined so as to carry
my Invention into effect, as the said methods may be varied according
to the circumstances of each particular case; and I believe any one
competent to construct an ordinary cupelo is competent to construct my
Invention from the description herein given.
I claim as my Invention adding to the ordinary cupelo a reservoir
or second cupelo, the said second cupelo or reservoir being so arranged
with respect to the first cupelo that the contents of the first cupelo and
reservoir or second cupelo may either be drawn off separately, or both
from the same tap hole; that is to say, the contents of the cupelo and
reservoir drawn off' from the tap hole of the said cupelo when a larger
quantity of iron is required than can be contained in one cupelo.
In witness whereof, I, the said Joseph Spencer, have hereunto
set my hand and seal, this Ninth day of December, in the
year of our Lord One thousand eight hundred and fifty-three.
