the United Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, during the term of fourteen years then next ensuing:
And whereas the said Joseph Levi Montefiore, on the Sixteenth day of November,
One thousand eight hundred and seventy, within the time prescribed by the said
Duins A

page_text: Letters Patent, caused a Specification in writing under his hand and seal of the
said Invention to be filed in the Great Seal Patent Office:
And whereas the Stamp Duty of fifty pounds was duly paid, and the said Letters
Patent produced, with the proper stamp affixed thereto at the Great Seal Patent
Office, within three years from the date of such Letters Patent; and also the Stamp
duly
Duty of one hundred pounds was a paid, and the said Letters Patent produced, with
the proper stamp affixed thereto at the Great Seal Patent Office within seven years
from the date of the said Letters Patent:
And whereas by an Indenture of Assignment bearing date the Third day of
December, One thousand eight hundred and seventy, and made between the said
Joseph Levi Montefiore of the one part, and the said George Montefiore Levi and
Charles Künzel of the other part, and duly registered in the Great Seal Patent
Office, the said Letters Patent and Invention were duly assigned to and vested in
the said George Montefiore Levi and Charles Künzel :
And whereas by an Indenture of Assignment bearing date the Fifteenth day of
May, One thousand eight hundred and seventy-four, and made between the said
George Montefiore Levi and Charles Künzel of the one part, and The Phosphor
Bronze Company, Limited, of 110, Cannon Street, in the City of London, of the

WHEREAS Her Most Excellent Majesty Queen Victoria by Her Letters Patent
bearing date the 17th day of May, in the year of our Lord 1870, in the thirty-
first year of Her reign,did for Herself, Her heirs and successors, give and grant unto
me, the said Joseph Levi Montefiore, Her special license that I; the said Joseph
Levi Montefiore, my executors, administrators, and and assigns, or such others as
I, the said Joseph Levi Montefiore, my execntors, 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 THE MANU-
FACTURE OF BRONZE," being a communication to me from abroad by George Monte-
fiore Levi, of Brussels, and Charles Künzel, of Liege, upon the condition (amongst
others), that I, the said Joseph Levi Montefiore, 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 saine 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 Joseph Levi Montefiore, 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 :-
This Invention relates to an improved manufacture of bronze, in which a
phosphoric substance, such as is hereafter mentioned, is introduced during the
process of melting the copper, tin, and other metals, which form the basis of the
metal known as "bronze," whereby its quality in regard to elasticity, hardness,
and toughness is considerably improved as compared with the bronze manufactured
in the ordinary way as hitherto adopted.

The introduction as herein described of the herein-after mentioned phosphoric
substances will be found to eliminate or neutralize the effect of the oxides found in
the ordinary bronze metal produced by the present melting process.
The fused
metal is thereby rendered more fluid, and the process of turning it into moulds
is thereby facilitated, so that the largest or smallest object of the most complicated
and most intricate character to be produced in bronze metal prepared by this
process may be cast or produced in a cast form without any material flaw.

Having ascertained by any convenient method of analysis the proportion of
phosphorous element necessary to deoxidize the bulk of alloy operated on a certain
excess of phosphorus or phosphoric substance is added to the proportion obtained,
and the quantity added should be varied in accordance with the nature of the
bronze metal required to be produced.
The phosphorus should be added in the form of phosphuret of copper or phosphuret
of tin prepared by any suitable method, and in such quantity that the phosphorus
contained therein should represent one-tenth to two per cent. of the total weight of

page_text: qualities
the metal operated upon. This proportion is to be determined by the quantities
sought for in the bronze, the hardness of the metal being proportionate to the
quantity of phosphorus added. This addition should be made after the perfect
fusion of the copper and tin. The various elements composing the bronze in a
fused state are then well stirred, and may be afterwards at once run from the
furnace pots or crucibles direct into the moulds.
Having now described and particularly set forth the nature of this Invention,
and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that I do not claim the use of the phosphorus generally
or otherwise than in the form of the phosphurets herein-before mentioned; but I
do not confine or restrict myself to the precise details which I have described or
referred to, as variations may be made therefrom without deviating from the
principles or main features of this Invention; but what I consider to be novel and
original, and thereform claim as the Invention secured to me by the herein-before
in part recited Letters Patent is, the manufacture of bronze by the use of the
herein-before mentioned phosphurets of copper and tin, substantially as herein
described.
In witness whereof, I, the said Joseph Levi Montefiore, have hereunto set my
hand and seal, this Fourteenth day of November, in the year of our Lord
One thousand eight hundred and seventy.

the above-written Disclaimer and Memorandum of Alteration is not, nor is any part
I hereby grant my Fiat, giving leave to the above-named George Alexander
Dick, on behalf of the Phosphor Bronze Company, Limited, as assignees of the
Letters Patent, to file in the Great Seal Patent Office, with the Specification

PROVISIONAL SPECIFICATION left by the said Joseph Levi Montefiore
at the Office of the Commissioners of Patents, with his Petition, on
the 17th May 1870.
I, JOSEPH LEVI MONTEFIORE, of 52, Kensington Gardens Square, in
the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF BRONZE," to be as
follows:-
This Invention relates to an improved manufacture of bronze in which
phosphorus or a phosphoric substance is introduced during the process
of smelting the copper, tin, and other metals which form the basis of
the metal known as "bronze," whereby its quality in regard to elasticity,

page_text: hardness, and toughness is considerably improved as compared with the
bronze manufactured in the ordinary way as hitherto adopted.
The introduction of phosphorus or phosphoric substances will be found
to eliminate or neutralize the effect of the oxides found in the ordinary
bronze metal produced by the present smelting process. The fused metal
is thereby rendered more fluid, and the process of running it off into
moulds is thereby facilitated, so that the largest or smallest object of
the most complicated and most intricate character to be produced in
bronze metal prepared by this process may be cast or produced in a cast
form without any material flaw.
Having ascertained by any convenient method of analysis the pro-
portion of phosphorous element necessary to deoxidize the bulk of alloy
operated on, a certain excess of phosphorus or phosphoric substance is
added to the proportion obtained, and the quantity added should be
varied in accordance with the nature of the bronze metal required to be
produced; such quantity of phosphorus or phosphoric substance may
be added in such manner and form as may be found most advantageous,
as will be well understood by persons conversant with the manufacture
of bronze. It is however preferred that the phosphorus should be added
in the form of phosphuret of copper or phosphuret of tin prepared by
any suitable method, and in quantity about one half to two per cent. of
the total bulk of the metal operated upon. The various elements com-
posing the bronze in a fused state are then well stirred, and may be
afterwards at once run from the furnace direct into the moulds.
