IMPROVEMENTS IN THE MANUFACTURE OF STEEL AND OF DIES AND OTHER ARTICLES IN STEEL
Year: 1874

page_text: LETTERS PATENT to James Noad, of St. Mary's Terrace, Pelly Road,
Plaistow, in the County of Essex, Engineer, for the Invention of
"IMPROVEMENTS IN THE MANUFACTURE OF STEEL AND OF DIES AND OTHER
ARTICLES IN STEEL."
Scaled the 26th June 1874, and dated the 23rd April 1874.
PROVISIONAL SPECIFICATION left by the said James Noad at the
Office of the Commissioners of Patents, with his Petition, on the
23rd April 1874.
I, JAMES NOAD, of St. Mary's Terrace, Pelly Road, Plastow, in the
County of Essex, Engincer, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE MANUFACTURE OF STEEL AND OF DIES AND
OTHER ARTICLES IN STEEL," to be as follows:-
This Invention has for its object improvements in the manufacture of
steel and of dies and other articles in steel. To effect these objects I make
a saturated solution of muriate of ammonia or sal ammoniac; in this
solution I dissolve equal quantities of wrought iron, cast iron, and steel,

page_text: scrap or pig, this is kept at 180 Fahrenheit till there is no signs of gas
arising. This solution is then passed through filtering cloth which must
be very bright and clear when filtered. I then evaporate by the means
of jacketed superheated steam, starting at 240 Fahrenheit and. rising to
380 Fahrenheit; this part of the process gives a fawn colored powder.
I make a saturated solution of sulphurate of iron or green copperas;
this is also filtered and evaporated by jacketed superheated steam rising
from 240 to 420 Fahrenheit to drive off all the acid, leaving a grey chrys-
talline powder. I then make a solution of powders; one and a half
ounce of the first powder, two ounces of the second powder, and ten fluid
ounces of distilled water. This solution is passed through filtering cloth;
it is then ready for the bath.
Arrangements for the Bath.-The bath is charged with this solution.
I then place in one side of the bath scrap iron, wrought, cast, or crude.
On the other side I place stripping plates designed in fine or heavy
work, sunken or risen, round or flattened. I then connect the poles of
one or more batteries, one pole to the scrap iron which is the anode
and the other to a piece of work for depositing on. I then place in the
front of the picce of work a perforated non-conducting screen charged
with dog-wood charcoal; if the work is for dies or medallions for striking
I prefer one-third of the anode to be steel. The batteries may be driven,
according to the work required.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Noad in the Great Seal Patent Office on
the 23rd October 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
NOAD, of St. Mary's Terrace, Pelly Road, Plaistow, in the County of
Essex, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her
Letters Patent, bearing date the Twenty-third day of April, in the
year of our Lord One thousand eight hundred and seventy-four, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs
and successors, give and grant unto me, the said James Noad,
Her special license that I, the said James Noad, my executors,
2

page_text: administrators, and assigns, or such others as I, the said James
Noad, my exccutors, 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 Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF STEEL AND OF DIES AND OTHER
ARTICLES IN STEEL," upon the condition (amongst others) that I, the said
James Noad, 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 James Noad, 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 thercof, that is to say :-
This Invention has for its object improvements in the manufacture of
steel and of dies and other articles in steel. To effect these objects I
make (1) a saturated solution of muriate of ammonia or sal ammoniac;
in this solution I dissolve wrought iron, cast iron, or steel (scrap or
pig), this is kept at 180 Fahrenheit till there are no signs of gas arising.
This solution is then passed through filtering cloth to render it very
bright and clear. When filtered I evaporate it by means of super-
heated steam in a surrounding jacket starting at 240 Fahrenheit and
rising to 380 Fahrenheit; this part of the process gives a fawn colored
powder.
2. I make a saturated solution of protosulphate of iron or green
copperas; this is also filtered and evaporated by superheated steam in a
surrounding jacket rising from 240 to 420 Fahrenheit to drive off all the
acid, leaving a grey chrystalline powder. I then make a solution of
powders; one and a half ounce of the first powder, two ounces of tho
second powder, and ten fluid ounces of distilled water. This solution is
passed through filtering cloth; it is then ready for the bath.
Arrangements for the Bath.-The bath is charged with this solution.
I then place in one side of the bath scrap iron, wrought, cast, or crude.

page_text: On the other side I place stripping plates designed in fine or heavy
work sunken or risen, round or flattened, or other plate or surface
desired to be covered. I then connect the poles of one or more batteries,
one pole to the scrap iron which is the anode, and the other to the picce
of work for depositing on. I then place in the front of the piece of
work a perforated non-conducting screen charged with charcoal; if the
work is for dies or medallions for striking I prefer one-third of the anode
to be steel.
Having thus described the nature of my Invention and the manner
of performing the same, I would have it understood that what I claim
as my improvements in the maunfacture of steel and of dies and other
articles in steel, is the deposition of steel by the means substantially as.
herein-before described.
In witness whereof, I, the said James Noad, have hereunto set
my hand and seal, this Twenty-first day of October, in the :
year of our Lord One thousand eight hundred and seventy-
four.
