page_text: 1, JOHN FRANCIS HALL of Norbury, Sheffield in the County of York Manager of
Steel Works do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of a new alloy of Steel or Iron and Nickel,
and has for its object to produce a metal or alloy possessing a combination of great
strength and toughness, having a very close grain and thus rendering it capable of
receiving a most brilliant polish.
I may premise that I am aware that steel has prior to my invention been treated
with Nickel but only in very small proportions, rarely exceeding one per cent., and
never above two per cent.
Now my present invention relates to the production of a new alloy of steel, or
melted wrought iron being a combination of either of the said metals with 24% up
to 50% of Nickel.
The steel may contain Carbon, silicon, manganese, chrome, Tungsten, or any of the
well known ingredients, but I prefer to have the said materials as low as possible, but
in some cases I may slightly increase the carbon to enable the steel to harden.
To carry out my invention, it is only necessary to melt the Iron or Steel by the Bessemer,
Siemens, or other like process or by the ordinary crucible process, and to add thereto
the required proportion of the ordinary Nickel of commerce. The resulting product
may either be cast to the desired shape, as a casting, or as an ingot it may be forged,
rolled or otherwise manipulated as may be required.
A metallic Alloy so composed is particularly adapted for the manufacture of Cannon,
gun barrels, shot and shell, Armour plates, Engravers plates, and other articles in
which great strength, or a smooth surface or fine polish is desirable or necessary.

page_text: I, JOHN FRANCIS HALL of Norbury, Sheffield in the County of York Manager of
Steel Works 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 refers to the manufacture of a new alloy of Steel or Iron and
Nickel, having for its object to produce a metal or alloy combining great strength with
toughness, also possessing a very close grain or texture, thus rendering it capable of
receiving a brilliant polish.
I wish it to be understood that I am aware that Steel has prior to this my invention,
been treated with Nickel but only in very small proportions, rarely exceeding one per
cent., and never above two per cent. of Nickel (as a matter of fact one per cent. may
be taken as the full extent of the addition).
Now my present invention, the result of research and experiments, relates to the
production of a new alloy of Steel, or of melted wrought iron, being a combination of
either of the above named metals with a proportion of nickel, which may vary from
2 per cent. to 30 per cent. of the whole.
The steel may contain carbon, silicon, manganese, chrome, Tungsten, or any of
the well known and commonly used ingredients, but I prefer to keep the said
materials as low as possible, although in some cases I may increase the Carbon.
To carry out the invention in manufacture, it is only necessary to melt the iron
or steel, by the Bessemer, Siemens, or other like process, or by the ordinary
crucible process, and to add thereto the required proportion of the ordinary Nickel
of commerce. The resulting product may either be cast to the desired shape, as
an ordinary casting, or as an ingot it may be forged, rolled or otherwise
manipulated as desired.
The metallic Alloy so constituted is particularly useful and valuable in the
manufacture of Cannon, Gun barrels, Shot and Shell, Armour plates, Engravers
plates, and other articles requiring great strength, a smooth surface, or a fine
polish.
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 :-
A metallic alloy of Steel or Iron and Nickel, consisting of a combination of either
of the two first named metals with a proportion of Nickel, varying (as required)
from 2 per cent. to 5 per cent. of the whole, for the purpose hereinbefore
specified.
