66, Chancery Lanc, in the County of Middlesex, Civil Engineer,
for the Invention of "IMPROVEMENTS APPLICABLE TO BLAST FURNACES."
-A communication from abroad by Theodore Frelinghuysen, Miner,
of Albany in the State of New York United States of America
Scaled the 18th November 1873, and dated the 8th September 1873.
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 8th September 1873.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVEMENTS APPLICABLE TO BLAST
FURNACES," to be as follows:-
The object of this Invention is to obviate the difficulty heretofore
experienced in keeping the plate which covers the cinder notch in
furnaces for the smelting of iron and other ores from burning away by
contact of the same with the cinder or slag during the process of
tapping cinder. To this end the cinder plate is made dish shape, or
with flanges of any desired depth, and is kept supplied with water in

page_text: quantities sufficient to last any required length of time, thus forming a
water cinder plate. The cinder plate is supplied with water by a pipe
from the ordinary water pipes used in connection with the furnace, a
waste pipe leading to the main waste pipe being attached, whereby a
The
constant flow of water through the cinder plate is ensured.
quantity of water admitted to the plate may be regulated by a valve in
the supply pipe.
It is desirable that that portion of the cinder plate which projects over
the dam plate should be tamped at each side with refuse fire-brick and
clay, leaving a space of several inches between the cinder notch and the
front of the plate which greatly facilitates the stopping up of the notch
after tapping and renders the whole process of tapping cinder less
laborious. Such provision also acts as a guide for the flow of cinder,
and tends to confine it to the furrow, and prevents it from spattering up
on to the front of the furnace and into the casting room.
The increased durability of the water cinder plates as compared with
the ordinary plates effects a great saving in the cost of material and
labor as regards the production of the cinder plates, and in the time,
labour, clay, loam used in setting the plates.
The ordinary cinder plate is frequently destroyed by two days' use,
while, this, my improved plate, will last for months. It, however, like
the old style of plate, is an independent piece, and detachable by simply
lifting it out where necessary for repairs or other purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Edward Newton in the Great Seal Patent 2
Office on the 6th March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of September, in the year of our
Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give

page_text: and grant unto me, the said Henry Edward Newton, Her special licence
that I, the said Henry Edward Newton, my executors, administrators.
and assigns, or such others as I, the said Henry Edward Newton, 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
APPLICABLE TO BLAST FURNACES," being a communication to me from abroad
by Theodore Frelinghuysen, Miner, of Albany, in the State of New
York, United States of America, upon the condition (amongst others)
that I, the said Henry Edward Newton, 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 Henry Edward Newton, 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, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thereon (that is to
say) :-
The object of this Invention is to obviate the difficulty heretofore
experienced in keeping the plate which covers the cinder notch in
furnaces for the smelting of iron and other ores from burning away by
contact of the same with the cinder or slag during the process of tapping
cinder. To this end the cinder plate is made dish shape, or with flanges
of any desired depth, and is kept supplied with water in quantities
sufficient to last any required length of time, thus forming a water
cinder plate.
In the accompanying Drawing Fig. 1 represents a front elevation
of the lower portion of a furnace having the improvement applied;
Fig. 2, a horizontal section on the line x, x; and Fig. 3, a vertical
section on y, y. Similar letters of reference indicate corresponding parts.
A is the body of the furnace, and B, the cinder plate, which is made
with flanges of any desired depth, and is supplied with water by a pipe b

page_text: from the ordinary water pipes used in connection with the furnace, a
waste pipe c leading to the main waste pipe being attached, whereby a
constant flow of water through the cinder plate is ensured. The quantity
of water admitted to the plate may be regulated by a valve in the supply
pipe. O is the furrow for the cinder; and D, the vent for the molten a
metal.
It is desirable that that portion of the cinder plate which projects over
the dam plate should be tamped at each side with refuse fire-brick and
clay, leaving a space of several inches between the cinder notch and the
front of the plate, which greatly facilitates the stopping up of the notch
after tapping, and renders the whole process of tapping cinder less
laborious. Such provision also acts as a guide for the flow of cinder
and tends to confine it to the furrow, and prevents it from spattering
on to the front of the furnace and into the casting room.
The increased durability of the water cinder plates as compared with
the ordinary plates effects a great saving in the cost of material and
labor as regards the production of the cinder plates, and in the time,
labor, clay, loam, and other materials used in setting the plates.
The ordinary cinder plate is frequently destroyed by two days' use,
while the improved plate will last for months. It is, however, like the a
old style of plate, an independent piece, and detachable by simply lifting
it out when necessary for repairs or other purposes.
Having now described the nature of the said Invention of " Improve-
ments applicable to Blast Furnaces," as communicated to me by my
foreign correspondent, and having explained the manner of carrying the 2
same into effect, I wish it to be understood that under the above in part
recited Letters Patent I claim, the flanged or hollow water cinder
plate B with the water supply and waste pipes b and c as and for the
purpose herein set forth.
In witness whereof; I, the said Henry Edward Newton, have here- 3
unto set my hand and seal, the Sixth day of March, in the year
of our Lord One thousand eight hundred and seventy-four.
