PROVISIONAL SPECIFICATION.
The Manufacture of Plates and other Articles from an Alloy or
Alloys of Copper and Nickel by Rolling at a Red Heat.
I, Sir HENRY HUSSEY VIVIAN, Baronet, of Singleton, Swansea, in the County of
Glamorgan, do hereby declare the nature of this invention to be as follows:-
According to my invention alloys are produced of nickel and copper in such pro-
portions and of such qualities that they can be rolled when at a red heat and such
alloys are rolled at this heat into bars plates sheets tubes and other articles thus
causing the cost of manufacture of such articles to be much less than by the old system
of rolling cold. The alloys produced are from their density and strength far more
valuable than copper or brass for purposes such as locomotive tubes, fire box plates and
other uses for which copper and brass are now employed whilst the cheap process of
hot rolling enables them to compete with such metals.
In order to produce the hot rolling alloys I take the purest copper and nickel I can
obtain and melt them together in the usual manner in any proportions between one
eighth per cent. of nickel and the remainder copper and 10 per cent. of nickel
and 90% of copper, both of which extremes and all intermediate proportions will roll
at a red heat, but as too large a proportion of nickel increases the difficulty of working
the metal causing it to be too hard and to crack at the edges as well as increasing
the cost of the alloy without any adequate improvement in its characteristics, I
prefer the alloy to consist of from 1 to 3 per cent. of nickel the remainder being
copper.
I cast the alloy into ingots either solid or hollow as the case may be, heat them in
an annealing furnace and roll them at a red heat precisely in the same manner as
copper is rolled.

I, Sir HENRY HUSSEY VIVIAN, Baronet, of Singleton, Swansea, in the County of
Glamorgan, 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 :-

portions and of such qualities that they can be rolled when at a red heat and such
alloys are rolled at this heat into bars plates sheets tubes and other articles thus

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
44
The manufacture of plates and other articles from an alloy or alloys of copper and
nickel containing from one tenth to ten per cent. of nickel by casting such alloy or
alloys into ingots and heating, and rolling these ingots at a red heat substantially as
described.
