A NEW METALLIC ALLOY
Year: 1863

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "A NEW
METALLIC ALLOY."-A communication from abroad by Henri Micolon,
of Paris, France.
Sealed the 16th February 1864, and dated the 22nd August 1863.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 22nd August 1863.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "A NEW METALLIC ALLOY," to be as follows:-
This new alloy is applicable to: the manufacture of all metal articles, bells,
hammers, anvils, rails, non-cutting tools, and other articles. In some of its
applications I run the alloy on to a core of iron. The alloy consists of iron,
preferably in the form of waste or. ribbands, or, of tin and steel, with manganese
and borax, to which a small proportion of wolfram is sometimes added. The
mixture preferred, particularly where the alloy is to be used for the manu-
facture of bells, is the following:-
20 parts of iron turnings or ribbands.
80 parts, ribbands of steel.
4 parts manganese.
4 parts of borax.
When desired to increase the tenacity of the alloy, two to three parts of
wolfram are added. When the crucible is ready, I pour in the iron and steel,

page_text: then the manganese, next the borax, and I re-charge with coke or coal. The
fusion of the mixture thus takes place directly in the cupola, and the mass is
run out into moulds. I obtain by this process of mixing and fusion in the
cupola, bells which possess the sonority of silver, while the cost, as compared
with that of bronze, is much less. If desired to give the bells the appearance
of bronze or copper, they may be subjected to an electro-metallic bath. If
anvils, hammers, or other non-cutting tools are to be produced, I proceed, as
before described, but I change the respective proportions of the iron and steel
according to the character of the tool, and as before stated, I sometimes run
the alloy on a core of iron, especially in the manufacture of rails and anvils.
For hammers of some descriptions I run the. alloy on a socket or iron tube,
into which the handle is inserted.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 22nd February 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of August, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Richard Archibald Brooman, Her special licence that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, my executors, adminis-
trators, 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 "A NEW METALLIC ALLOY," (communicated to me from
abroad by Henri Micolon, of Paris, France," upon the condition (amongst
others) that I, the said Richard Archibald Brooman, 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 naturo
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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, 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 :-.
This new allow is applicable to the manufacture of all metal articles, bells,
hammers, anvils, rails, cutting and non-cutting tools, cannon, and other articles.
In some of its applications I run the alloy on to a core of iron. The alloy
consists of iron (preferably in the form of waste or ribbands) and of steel:
The mixture is effected. by the addition of fluxes, such as manganese and borax,
to which a small proportion of wolfram is sometimes added under the influence
of heat from coal or coke. The whole is mixed together by preference in
an ordinary cupola, or in a reverberatory furnace, that is to say, there is no
crucible, and all the ingredients are in contact with the fuel in the cupola.
The mixture preferred, particularly where the alloy is to be used for the
manufacture of bells, is the following:-

page_text: liable to wear. I manufacture anvils in the same manner, that is to say, I
run the alloy on to a core of iron. For the manufacture of hammers of some
descriptions, I run the alloy on an iron socket or tube, into which the handle
is inserted. To impart malleability to the alloy for some purposes, I anneal
it. The annealing softens the alloy, and allows of its being cut and turned
to ornamental and other forms. For edged tools the alloy may be annealed
and then tempered to harden the cutting edge.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim the new metallic
alloy, produced substantially, in manner, and in or about the proportions herein-
before described.
In witness' whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-second day of February, One
thousand eight hundred and sixty-four.
R. A. BROOMAN. (L.S.)
