PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Metallic Alloys
or Compounds.
I, GEORGE EDWARD VAUGHAN, of No. 57, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, which has
been communicated to me from abroad by Lazare Weiller, of Angoulême, in the
Republic of France, to be as follows :-
This invention relates to the improvement of the tenacity, density and other
mechanical properties of copper and certain alloys or compounds of copper, such, for
example, as bronze. The object of this invention is effected by the addition of a
certain quantity of zinc or spelter to copper or to its alloys, such as, bronze, with
which metal or alloy either silicium or sodium or both have been previously
combined, so as to form silicious copper or sodium copper or sodium-silicium-copper
or silicious bronze or sodium bronze or sodium silicium-bronze, or to copper or to
bronze which has been previously melted with, or in the presence of, silicium or sodium
or silicium and sodium combined.
For the purpose of this invention the silicious copper, the sodium copper, the
sodium-silicium-copper, the silicious bronze, the sodium bronze or the sodium-
silicium-bronze or the copper or the bronze which has been previously melted with,
or in the presence of, silicium or sodium or silicium and sodium combined, as
herein before stated, is brought to a state of fusion, when a quantity of zinc or spoltor
is added thereto.
The quantity of zinc or spelter added varies according to the metal or to the
metal compound or alloy to be treated and the result it is desired to attain, the
proportion of zinc or spelter added being larger when the alloy to be produced is of
the nature of brass, and less when an alloy of the nature of bronze is desired.
It will be understood that the invention is applicable to compounds or alloys of
copper other than bronze.

Improvements in the Manufacture of Metallic Alloys
or Compounds.
I, GEORGE EDWARD VAUGHAN, of No. 57, Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, which has
been communicated to me from abroad by Lazare Weiller, of Angoulème, in the
Republic of France, 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 the improvement in tenacity and ductility of certain
alloys, preparations or compounds of copper hereinafter referred to, and the desired
object is effected by the addition of a certain quantity of zinc or spelter to them.
The said alloys, preparations, or compounds of copper are copper or bronze, with
which, either silicium alone, or sodium alone, or both, bave been previously combined,
so as to form silicious copper, or sodium copper, or sodian-silicium-copper, or
silicious bronze, or sodium bronze, or sodium-silicium-bronze, or copper or bronze
TD 1

page_text: which has been previously melted with, or in the presence of, silicium alone or sodium
alone, or silicium and sodium combined.
For the purpose of this invention, the silicious copper, the sodium copper, the
sodium-silicium-copper, the silicious bronze, the sodium bronze, or the sodium-
silicium-bronze, or the copper or the bronze, which has been previously melted with,
or in the presence of, silicium alone, or sodium alone, or silicium and sodium
combined, as herein before mentioned, is brought to a state of fusion, and a quantity
of zinc or spelter is added thereto. The quantity of zinc or spelter added, varies
according to the metal, or to the metal compound or alloy to be treated, and the
result it is desired to attain, the proportion of zinc or spelter added being larger when
the alloy to be produced is of the nature of brass, and less when an alloy of the nature
of bronze is required.
It will be understood that when an alloy of the nature of brass is required, it is
botter to start with silicium copper, sodium copper, or sodium-silicium-copper, or
with copper which has been previously melted with, or in the presence of, silicium
alone, or sodium alone, or silicium and sodium combined; and when an alloy of the
nature of bronze is required, it is better to start with silicium bronze, sodium bronze,
or sodium-silicium bronze, or with bronze which has been previously melted with,
or in the presence of, silicium alone, or sodium alone, or silicium and sodium
combined, otherwise tin must be added during the process in the usual way to form
the bronze.
The proportion of zinc or spelter to be added to silicium copper, sodium copper,
or sodium-silicium-copper, or to copper which has been proviously melted with, or
in the presence of, silicium alone, or sodium alone, or silicium and sodium combined,
if the alloy to be produced is to be of the nature of brass, may be such as is usually
added to copper in the manufacture of various qualities of brass, but not more than
40% of the finished alloy. If the alloy to be produced is to be of the nature of
bronze, the proportion of zinc or spelter added to the silicium bronze, sodium bronze,
or sodium-silicium-bronze, or to the bronze which has been previously melted with,
or in the presence of, silicium alone, or sodium alone, or silicium and sodium
combined, may be as low as 0.1 per cent., but in any case, the finished alloy must
not contain more than 5% of zinc or spelter. When zinc or spelter has been added
to bronze which has been previously combined with, or melted with, or in the
presence of, silicium alone, or sodium alone, or silicium and sodium combined, as
above stated, for the purpose of making an alloy of the nature of bronze, the zinc or
spelter may be afterwards eliminated to any required degree, by continued heating or
remelting, it being sufficient for some purposes to leave only a trace of zinc or spelter
in the finished alloy.
I do not claim the combination of copper or bronzo with silicium alone, or sodium
alone, or with silicium and sodium combined, or the melting of copper or bronze in the
presence of silicium alone, or sodium alone, or of silicium and sodium combined, as
forming any part of the presont invention.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, I declare that what I
claim is :-
First. The improvements in the manufacture of metallic alloys or compounds,
consisting of the addition of zinc, or spelter to copper, combined with silicium alone,
or sodium alone, or with silicium and sodium combined, or to copper, which has
been previously melted with, or in the presence of, silicium alone, or sodium alone,
or silicium and sodium combined, substantially as hereinbefore described.
Secondly. The improvements in the manufacture of metallic alloys or compounds,
consisting of the addition of zinc, or spelter to bronze, combined with silicium alone,
or sodium alone, or with silicium and sodium combined, or to bronze, which has
been previously melted with, or in the presence of, silicium alone, or sodium alone,

page_text: 5
or silicium and sodium combined, (whether the zinc be allowed to remain in the
preparation, or be subsequently removed) substantially as hereinbefore described.
Thirdly. The manufacture or use of alloys, preparations, or compounds, made or
treated in the manner claimed in the preceding claims.
