IMPROVEMENTS IN FURNACES OR APPARATUS EMPLOYED IN THE MANUFACTURE AND CASTING OF IRON, STEEL, AND OTHER METALS."
Year: 1874

page_text: LETTERS PATENT to James Stone, of West Bromwich, in the County
of Stafford, for the Invention of "IMPROVEMENTS IN FURNACES OR
APPARATUS EMPLOYED IN THE MANUFACTURE AND CASTING OF IRON, STEEL,
AND OTHER METALS."
PROVISIONAL SPECIFICATION left by the said James Stone at the
Office of the Commissioners of Patents, with his Petition, on the
30th October 1874.
I, JAMES STONE, of West Bromwich, in the County of Stafford, do
3 hereby declare the nature of the said Invention for "IMPROVEMENTS IN
FURNACES OR APPARATUS EMPLOYED IN THE MANUFACTURE AND CASTING OF IRON,
STEEL, AND OTHER METALS," to be as follows:-
Much difficulty and inconvenience is experienced in conveying molten
metal from blast, cupola, or other melting furnaces to refineries, puddling,
and other furnaces for subsequent treatment, or in running large
quantities of molten metal into moulds for casting purposes, and my
improvements relate to improved means of conveying molten metal

page_text: from blast, cupola, or other furnaces or processes to other furnaces,
apparatus, or places for subsequent treatment or use, as may be required.
For this purpose I employ a portable furnace or receiver mounted upon
a frame and wheels, the furnace or receiver being formed with a chamber
to receive the molten metal from the blast, cupola, or other furnace, in {
which portable furnace the metal can be maintained in a molten state
for any length of time by means of a fire-grate or furnace combined
therewith, by which heat may be constantly applied to keep the metal in
a molten state, the whole being advantageously arranged to act as a
reverberatory furnace or otherwise, as may be desired. By this means 1
molten metal may be readily conveyed to any distance from one process
or operation to another without cooling or loss of temperature.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Stone in the Great Seal Patent Office on
the 30th April 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
STONE, of West Bromwich, in the County of Stafford, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of October, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
cighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said James Stone, Her special license
that I, the said James Stone, my executors, administrators, and assigns,
or such others as I, the said James Stone, 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 OR
APPARATUS EMPLOYED IN THE MANUFACTURE AND CASTING OF IRON, STEEL, AND
OTHER METALS," upon the condition (amongst others) that I, the said
James Stone, my exccutors or administrators, by an instrument in

page_text: 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 James Stone, 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 thereof, that is to say :-
Much difficulty and inconvenience is experienced in conveying molten
metal from blast, cupola, or other melting furnaces to refineries,
puddling, and other furnaces for subsequent treatment, or in running
large quantities of molten metal into moulds for casting purposes,
and my improvements relate to improved means of conveying molten
metal from blast, cupola, or other furnaces or processes to other
furnaces, apparatus, or places for subsequent treatment or use, as may
be required.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section, Figure 2 an elevation, Figure 3 a plan
in section, and Figure 4 a plan, and Figures 5 and 6 transverse sections
of a portable furnace or apparatus arranged and constructed in
accordance with my Invention.
A is a portable furnace. or receiver mounted upon a frame a and
wheels a', the furnace or receiver A being formed with a chamber B to
receive the molten metal from the blast, cupola, or other furnace, in
which portable furnace A the metal can be maintained in a molten state
for any length of time by means of a fire-grate or furnace 6 combined
therewith, by which heat may be constantly applied to keep the metal
in a molten state, the whole being advantageously arranged to act as a
reverberatory furnace, as shown, in the Drawing, or otherwise, as may be
desired. The chamber B is constructed to hold a given quantity or
weight of molten metal, and any excess of such given quantity will flow

page_text: over the bridge c, down the channel c', and be discharged at the back
end of the portable furnace A. This portable furnace is constructed and
arranged with suitable doors and openings for introducing the fuel and
molten metal, which latter can be discharged when required by means of
a tap hole, as is well understood. By these means molten metal may
be readily conveyed to any distance from one process or operation
to another without cooling or loss of temperature.
Portable furnaces of this description may be advantageously employed
for conveying molten metal to pits or moulds for casting purposes.
·
Having thus described the nature of my Invention and the manner
of performing or carrying the same into practice, I would have it under-
stood that I do not intend to confine myself to the exact details herein-
before described, as the same may be considerably varied without
departing from the true character of my Invention, but what I claim is,
the improved arrangement and construction of furnaces or apparatus
employed in the manufacture of metal by mounting the same upon
wheels or runners, for the purpose of maintaining the metal contained in
such furnaces or apparatus in a molten state, so that it can be conveyed
from blast, cupola, or other furnaces, refineries, or processes to other
furnaces, apparatuses, or places for subsequent treatment or use without
loss of heat, substantially in the manner herein-before described and
represented in the Drawings hereunto annexed.
In witness whereof, I, the said James Stone, have hereunto set
my hand and seal, this Twenty-seventh day of April, in the
year of our Lord One thousand eight hundred and seventy-
