A New or Improved Metallic Alloy.
We, WILLIAM WOOLF of 26 Cowper Street, London, Manufacturer, and
JOHN ANDREWS of Lupin Street Metal Works, Lupin Street, Birmingham in
County of Warwick, Metal Founder, do hereby declare the nature of this invention
to be as follows:-
This invention consists in a new or improved metallic alloy composed of copper,
nickel, spelter, regulus, and copper-flux in the following proportions, or thereabout,
namely, 42 lbs. of copper, 20 lbs. of mixed nickel, 18 lbs. of spelter, 4 ounces of
regulus, and 8 ounces of copper-flux.
To prepare the alloy we take the copper, which should be as pure as possible
(say the quality known as B.S. copper), and heat it in a crucible, or otherwise, to
near the melting point; we then add the mixed nickel (which consists of a
compound of copper and nickel) and fuse the two, that is to say the copper and
mixed nickel together, and add a suitable quantity of a flux composed of salt,
borax and sal-enixon mixed together in the proportions of about 1 lb. of common
salt, half a pound of borax and one and a half pounds of sal-enixon. We then
add gradually the spelter (which should be as pure as possible, say the quality known
as Swansea cake spelter), regulus, and copper-flux, the latter preferably composed
of copper-scale phosphorized. The molten mixture is stirred during the process,
preferably with a wooden stirrer, and ground charcoal may be added to prevent
"mudding."
When the metals are thoroughly incorporated the resulting alloy is poured into
moulds.
We do not confine ourselves to the precise proportions or process above described
for producing the alloy, as they may be varied without departing from the nature
of the invention.

A New or Improved Metallic Alloy.
We, WILLIAM WOOLF, of 26 Cowper Street, London, Manufacturer, and
JOHN ANDREWs of Lupin Street Metal Works, Lupin Street, Birmingham in
the County of Warwick, Metal Founder, do hereby declare the nature of this
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 consists in a new or improved metallic alloy composed of copper,
nickel, spelter regulus of antimony and copper-flux in the following proportions or
thereabout, namely, 42 lbs. of copper, 20 lbs. of mixed nickel, 18 lbs. of spelter,
4 ounces of regulus of antimony, and 8 ounces of copper-flux.

page_text: To prepare the alloy we take the copper, which should be as pure as possible
(say the quality known as B.S. copper), and heat it in a crucible, or otherwise, to
near the melting point; we then add the mixed nickel (which consists of a compound
of one part of B.S. copper and one part of pure nickel) and fuse the two, that is
to say the copper and mixed nickel together, and add a suitable quantity of a flux
composed of salt, borax and sal-enixon mixed together in the proportions of
about 1 lb. of common salt, half a pound of borax, and one and a half pounds of
sal-enixon. We then add gradually the spelter (which should be as pure as
possible, say the quality known as Swansea cake spelter), regulus of antimony and
copper-flux, the latter preferably composed of copper-scale, phosphorized. The
molten mixture is stirred during the process, preferably with a wooden stirrer, and
ground charcoal may be added to prevent "mudding.'
When the metals are thoroughly incorporated the resulting alloy is poured into
moulds.
We do not confine ourselves to the precise proportions or process above described
for producing the alloy, as either may be varied without departing from the nature
of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
First. The metallic alloy composed of copper, mixed nickel, spelter, regulus of
antimony and copper-flux combined together in the proportions, or thereabout,
herein specified.
Second. The metallic alloy composed of copper, mixed nickel, spelter, regulus
of antimony and copper-flux, produced by melting together the copper and mixed
nickel then adding a suitable flux composed of common salt, borax and sal-enixon,
and finally adding the spelter, regulus of antimony and copper-flux, substantially as
described.
