Year: 1874

page_text: LETTERS PATENT to John Carter Ramsden, of Smith House, Light-
cliffe, in the Parish of Halifax, in the County of York, Silk.
Manufacturer, for the Invention of "AN IMPROVED METHOD OR PROCESS.
OF AND APPARATUS FOR SMELTING, REFINING, MELTING, CONVERTING, OR.
PURIFYING IRON, AND OTHER MINERAL OR METALLIC SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said John Carter Ramsden
at the Office of the Commissioners of Patents, with his Petition,
on the 26th March 1874.
I, JOHN CARTER RAMSDEN, of Smith House, Lightcliffe, in the
Parish of Halifax, in the County of York, Silk Manufacturer, do hereby
..declare the nature of the said Invention for "AN IMPROVED METHOD OR
PROCESS OF AND APPARATUS FOR SMELTING, REFINING, MELTING, CONVERTING, or
PURIFYING IRON, AND OTHER MINERAL OR METALLIC SUBSTANCES," to be as
follows:-

page_text: of the gases arising from the decomposition of water along with some
or one of the volatile hydrocarbons in conjunction with solid carbona-
ccous fuel, as described in the Specification of Letters Patent granted
to me and bearing date the 6th September 1872, No. 2650.
In carrying out this my said Invention I employ a series of reverbatory
furnaces connected with each other, and a through communication
from the front to the end. These furnaces have the usual fire-
grates and inclined table or beds for the metal. Coal or coke can be
used, either or both, and the said fuel can be fed in by hand or by
mechanical means. The gases are fed in at the front furnace,
No. 1, pass over the fire therein, mix with the gases arising therefrom,
and pass over and amongst the metals under operation, and through
an orifice at the end of this furnace they pass through into furnace
No. 2, and so on throughout the series. At the end of the furnaces
they pass into a chamber containing a number of pipes through
which the air is conveyed necessary to support combustion in the
furnaces, and from thence they are taken away either by means of a
chimney, or they can be conveyed to a blast furnace and there again
utilized, or they may be forced through melted metal in conjunction
with air in manner somewhat similar to what is now known as the
Bessemer process. These said gases can be used in manner just
described without the necessity of being first passed through the rever-
batory furnaces when it is found desirable to do so. These said gases;
instead of being fed into the front of No. 1 furnace, as previously
described, and thus pass through the series, may be conveyed along
with the air necessary for combustion through the pipes in the hot
chamber, and thence by means of a pipe or pipes discharged into the fire.
of each furnace.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of March, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, for. Herself, Her heirs and successors, give
and grant unto me, the said John Carter Ramsden, Her special licence
that I, the said John Carter Ramsden, my executors, administrators,
and assigns, or such others as I, the said John Carter Ramsden, 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 "AN IMPROVED
METHOD OR PROCESS OF AND APPARATUS FOR SMELTING, REFINING, MELTING, CON-
VERTING, OR PURIFYING IRON, AND OTHER MINERAL OR METALLIC SUBSTANCES,"
upon the condition (amongst others) that I, the said John Carter
Ramsden, 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 John Carter Ramsden, do hereby
declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained. in
and by the following statement (that is to say)
.
The object of this Invention is to smelt, purify, melt, convert, or.
refine iron, and other mineral or metalic substances, by the aid or adjunct
of the gases. arising from the decomposition of water along with some
or one of the volatile hydrocarbons in conjunction with solid car-
bonaccous fuel, as described in the Specification of Letters Patent granted
me bearing date the Sixth September One thousand eight hundred and.
seventy-two, Number 2650.
In carrying out this my said Invention I employ a series of reverbatory.
furnaces connected with each other, and a through communication
from the front to the end. These furnaces. have the usual fire:
grates and inclined tables or beds for the metal. Coal or çokë can be
used, either or both, and the said fuel can be fed in by hand or by:

mechanical means. The gases are fed in at the front of furnace,
Number 1, pass over the fire therein, mix with the gases arising there-
from, and pass over and amongst the metals under operation, and
through an orifice at the end of this furnace they pass through into
furnace Number 2, and so on throughout the series. At the end
of the furnaces they pass into a chamber containing a number of pipes
through which the air is conveyed necessary to support combustion in
the furnaces, and from thence they are taken away, either by means of a
chimney, or they can be conveyed to a blast furnace and there again
utalized; or they may be forced through melted metal in conjunction
with air, in manner somewhat similar to what is now known as the
"Bessemer process." These said gases. can be used in manner just
described without of necessity being first passed through the rever-
batory furnaces when it is found desirable to do so. These said gases
instead of being fed into the front of Number 1 furnace, as previously
described; and thus passing through the series, may be conveyed along
with the air necessary for combustion through the pipes in the hot
chamber, and thence by means of a pipe or pipes discharged into the fire
of each furnace.
Such being the object of the said Invention its practical working
will be readily understood by persons conversant with the construc
tion of furnaces, and the dealing with metals from the following
description.
. The object of this Invention is to smelt, purify, melt, convert, or
refinc iron and other mineral or metalic substances, by the aid or
adjunct of the gases arising from the decomposition of water along with
some or one of the volatile hydrocarbons in conjunction with solid car-
bonaceous fuel, as described in the Specification of Letters Patent granted
me bearing date the Sixth September One thousand eight hundred and.
seventy-two, Number 2650.
In carrying out this my said Invention I employ a series of rever-
batory furnaces connected with each other, and a through communica-
tion from the front to the end. These furnaces have the usual fire-
grates and inclined tables or beds for the metal. Coal or coke can be
used either or both, and the said fuel can be fed in by hand, or by
mechanical means. The gases are fed in at the front of furnace,
Number 1, pass over the fire therein, mix with the gases arising there-
from, and pass over and amongst the metals under operation, and

described without of necessity being first passed through the rever-
batory furnaces when it is found desirable to do so.
These said gases
instead of being fed into the front of Number 1 furnace, as previously
described, and thus passing through the series may be conveyed along
with the air necessary for combustion, through the pipes in the hot
chamber, and thence by means of a pipe or pipes discharged into the
fire of cach furnace.
In witness whereof, I, the said John Carter Ramsden, have hereunto
set my hand and seal, this Twenty-third day of September, in the
year of our Lord One thousand eight hundred and seventy-
four
