IMPROVEMENTS IN FURNACES FOR THE SMELTING IRON ORE AND IRON STONE, AND OTHER STONES AND ORES
Year: 1855

page_text: LETTERS PATENT to Daniel Dalton, of Chester, Ironmaster, for the
Invention of "IMPROVEMENTS IN FURNACES FOR THE SMELTING IRON ORE
AND IRON STONE, AND OTHER STONES AND ORES."
Scaled the 3rd November 1855, and dated the 4th May 1855.
PROVISIONAL SPECIFICATION left by the said Daniel Dalton at the
Office of the Commissioners of Patents, with his Petition, on the 4th
May 1855. .
I, DANIEL DALTON, of Chester, Ironmaster, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN FURNACES FOR THE SMELTING IRON ORE
AND IRON STONE, AND OTHER STONES AND ORES," to be as follows:-
This Invention has for its object a peculiar construction of furnace for
smelting iron ore and iron stone, and other stones and ores. For this purpose
the chamber of the furnace is to be built with a feed mouth at top, similar to
a blast furnace. At the lower part this chamber is formed hollow, to receive
the metal as it descends, and from which it is to bo tapped. This furnace bas
at one or more sides a fire-place, the heat and products from which pass
towards the chamber of the furnace in which the ore is placed. At the side
of the furnace rises a flue, or the flue may surround or partially surround the
furnace. A damper is used to regulate the draft up such flue; or the furnace
may be constructed without the flue or flues, though I consider it best to
have them.

by the said Daniel Dalton in the Great Seal Patent Office on the
3rd November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANIEL
DALTON, of Chester, Ironmaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by 1er Letters
Patent, bearing date the Fourth day of May, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs aml successors, give and grant into me,
the said Daniel Dalton, Her special licence that I, the said Daniel Dalton,
my executors, administrators, and assigns, or such others as I, the said
Daniel Dalton, 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 THE SMELTING IRON ORE AND IRON STONE, AND OTHER STONES AND
ORES," upon the condition (amongst others) that I, the said Daniel Dalton,
by an instrument in writing under my hand and seal, 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 Daniel Dalton, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof (that is to say):-
―
This Invention has for its object a peculiar construction of furnace for smelt-
ing iron ore and iron stone, and other stones and ores. For this purpose the
chamber of the furnace is to be built with a feed mouth at top, similar to a
blast furnace. At the lower part this chamber is formed hollow, to receive the
metal as it descends, and from which it is to be tapped. This furnace has at
one or more sides a fire-place, the heat and products from which pass towards
the chamber of the furnace in which the ore is placed. At the side of the
furnace rises a flue, or the flue may surround or partially surround the furnace.
A damper is used to regulate the draft up such flue; or the furnace may be
constructed without the flue or flues, though I consider it best to have them.

page_text: And in order that my said Invention may be fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed,
which shows a longitudinal section of a furnace constructed according to my
Invention.
A is a feed mouth or hopper, into which the ore and fuel is placed, and from
which it descends to the body of the furnace B, where it is exposed to the
flame from the fire C; D is the chimney or flue, which is here shewn passing
up by the side of the feed mouth or hopper A, but it may be otherwise
arranged; E and F are the two tap holes; the lower one E is to withdraw the
inetal from the furnace as it runs down, and the upper one F is for tapping
off the slag.
Having thus described the
performing the same, I would
nature of my Invention, and the manner of
have it understood that I do not confine myself
to the exact details described; but what I claim is, the peculiar construction
of furnace for smelting iron ore and iron stone, and other stones and ores,
herein-before described.
In witness whereof, I, the said Daniel Dalton, have hereunto set my
hand and seal, this Thirteenth day of October, in the year of our Lord
One thousand eight hundred and fifty-five.
Witness,
ALFRED DALTON,
Chester.
DANIEL DALTON. (LS.)
