A NEW OR IMPROVED METALLIC ALLOY
Year: 1862

page_text: LETTERS PATENT to Albert Lewis Woolf, of the Firm of Woolf, Brothers,
of Birmingham, in the County of Warwick, Wholesale, Jewellers, for
the Invention of "A NEW OR IMPROVED METALLIC ALLOY."
Sealed the 19th May 1863, and dated the 25th November 1862.
PROVISIONAL SPECIFICATION left by the said Albert Lewis Woolf at
the Office of the Commissioners of Patents, with his Petition, on the
25th November 1862.
Tr
I, ALBERT LEWIS WOOLF, of the Firm of Woolf, Brothers, of Birmingham,
in the County of Warwick, Wholesale Jewellers, do hereby declare the nature
of the said Invention for "A NEW OR IMPROVED METALLIC ALLOY," to be as
follows:-
My Invention consists of a new or improved metallic alloy, which is highly
malleable and ductile, and of a colour scarcely to be distinguished from that
of gold. The said alloy is not liable to oxidize or tarnish, and is suited for
the manufacture of jewellery; it may also be applied to other purposes. The
said alloy is composed of ninety parts by weight of copper, seven and a-half
parts by weight of aluminum, and two and a half parts by weight of gold.
In making the said alloy it is only necessary to melt together in a crucible
the respective quantities of the several metals composing it, when, on fusion,
the metals immediately enter into alloy.

by the said Albert Lewis Woolf in the Great Seal Patent Office on the
19th May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALBERT
LEWIS WOOLF, of the Firm of Woolf, Brothers, of Birmingham, in the County
of Warwick, Wholesale Jewellers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of November, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Albert Lewis Woolf, Her special licence that I, the said Albert Lewis
Woolf, my executors, administrators, and assigns, or such others as I, the
said Albert Lewis Woolf, 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
"A NEW OR IMPROVED METALLIC ALLOY," upon the condition (amongst others)
that I, the said Albert Lewis Woolf, 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 Albert. Lewis Woolf, 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:-
100 mins.
My Invention consists of a new or improved metallic alloy, which is highly
malleable and ductile, and of a colour scarcely to be distinguished from that
of gold. The said alloy is less liable to oxidize or tarnish than other base metals
or alloys,' and is suited for the manufacture of jewellery; it may also be applied
to other purposes. The said alloy is composed of from ninety to one hundred
parts by weight of copper, from five to seven and a half parts by weight of
aluminium, and two and a half parts by weight of gold. In making the said
alloy it is only necessary to melt together in a crucible the respective
quantities of the several metals composing it, when, on fusion, the metals
immediately enter into alloy.

page_text: I do not limit myself to the precise proportions herein-before stated of the
several metals of which my new or improved alloy is composed; but I have
found that an alloy composed of ninety-five parts by weight of copper, five
parts by weight of aluminium, and two and a half parts by weight of gold, is
the best for the manufacture of jewellery, and for various other purposes.
The proportions may, however, be modified within the limits herein-before
described without materially changing the character of the alloy.
Although I have herein-before described the proportions which, in practice,
I have found to answer best in manufacturing my new or improved alloy, yet
I do not limit myself thereto, as the proportions may be varied without
departing from the nature of my Invention. As the furnaces, crucibles, and
other appliances which I use in carrying my Invention into effect differ in
no respect from those generally used in melting metals and making alloys I do
not consider it necessary to describe the same.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I claim as
my Invention a new or improved metallic alloy composed of copper, aluminium,
and gold, as herein described.
In witness whereof, I, the said Albert Lewis Woolf, have hereunto
set my hand and seal, this Twelfth day of May, in the year of our
Lord One thousand eight hundred and sixty-three.
Witness,
WILLIAM CRAWFORD.
ALBERT LEWIS WOOLF. (L.S.)
