I WILLIAM THOMAS SUGG of Regency Street in the City of Westminster,
Engineer do hereby declare the nature of this invention to be as follows:
. The object of this invention is to produce a metallic alloy especially for use in the
manufacture of cooking utensils, which alloy will not be discoloured or otherwise
deleteriously affected by acids or other substances.
To this end the invention consists in the combination of copper aluminium and
silver which produces a homogeneous hard tough alloy which can be rolled and
hammered.
In carrying out my invention I take of aluminium ten per cent and of silver one
per cent and I combine them together preferably by heat. I next take this com-
bination and add it to the copper (89 per cent) in a molten state stirring the while in
order to obtain a complete mixture of the several ingredients and the-molten metal
may be cast into ingots for future use or made at once by casting into cooking
utensils.
The above proportions I have found produce very satisfactory results but I would
have it understood that I do not intend to confine myself to such proportions as for
some purposes I may find it desirable to increase or diminish the quantity of silver
for example varying the quantity of copper according to the circumstances.
I may also remark that I have referred to cooking utensils by way of illustra-
tion only as the alloy produced may obviously be used for other purposes in which
it is desirable to employ a non oxidizable metal.

I WILLIAM THOMAS SUGG of Regency Street in the City of Westminster,
Engineer, 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 :-
The object of this invention is to produce a metallic alloy especially for use in the
manufacture of cooking utensils, which alloy will not become discoloured or otherwise
deleteriously affected by the action of acids or other products resulting from the
cooking operations.
To this end, the invention consists in the combination of copper, aluminium, and
silver, which produces a homogeneous, hard, tough alloy, which can be rolled and
hammered.
In carrying out my invention, I take of aluminium ten per cent, and of silver one
per cent, and I combine them together, preferably by heat. I next take this com-

page_text: bination, and add it to the copper (89 per cent) in a molten state, stirring the
while, in order to obtain a complete mixture of the several ingredients, and the
molten metal may be cast into ingots for future' use, or made at once, by casting,
into cooking utensils.
The above proportions I have found produce very satisfactory results, but I would
have it understood that I do not intend to confine myself to such proportions, as, for
some purposes, I may find it desirable to increase or diminish the quantity of silver,
for example, varying the quantity of copper according to the circumstances.
I may also remark that I have referred to cooking utensils by way of illustration
only, as the alloy produced may obviously be used for other purposes in which it is
desirable to employ a non-oxidisable metal.
Having now, particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, I declare that what I claim is :-
A metallic alloy composed of copper, aluminium, and silver; in or about the propor-
tions given.
