PROVISIONAL SPECIFICATION.
An Improved Process of Manufacturing Iron and Steel.
We, ANDREW TURNER, of 40, St. Lawrence Street, Greenock, Ironmoulder,
ARCHIBALD BAIRD, of 59, Waterloo Street, Glasgow, Steel Manufacturer, and
MATTHEW BARR BAIRD, of 59, Waterloo Street, Glasgow, Steel Manufacturer,
do hereby declare the nature of this invention to be as follows:-
Our invention consists in manufacturing iron and steel by an improved
process.
In carrying out our invention, we, under one method, first reduce a certain
quantity of the crude or raw metal or material to a molten state in a furnace
or vessel of any suitable construction. We then introduce into this molten
metal or material a quantity of pure metal or material, obtained or reduced by
electricity. The reduction of the pure metal or material, which is preferably
malleable iron when steel is being manufactured, is effected by placing it, by
preference, in proximity to the furnace or vessel containing the molten, crude metal
or material and then passing through it a current of electricity, generated by a
dynamo or in any other well known manner. The heat generated by the passage
of the electric current through the pure metal or material reduces it and the pure
molten metal thus produced is dropped, put or conducted into the furnace or vessel
containing the molten crude metal or material and is mixed therewith. By the
addition of the pure molten metal or material the percentage of carbon and other
elements in the combined mass can be regulated to suit the requirements for which
the metal is to be used.
The crude metal or material may, if desired be first reduced in a furnace and
then run into a mixing vessel or pot into which the pure metal or material is
introduced.
Instead of manufacturing the iron or steel according to the method hereinbefore
described the whole of the metal or material may be reduced by the electrical
agency alone.

COMPLETE SPECIFICATION.
An Improved Process of Manufacturing Iron and Steel.
We, ANDREW TURNER, of 40, St. Lawrence Street, Greenock, Ironmoulder,
ARCHIBALD BAIRD, of 59, Waterloo Street, Glasgow, Steel Manufacturer, and
MATTHEW BARR BAIRD, of 59, Waterloo Street, Glasgow, Steel Manufacturer,
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:-
Our invention consists in manufacturing iron and steel by an improved
process.
In carrying out our invention, we, under one method, first reduce a certain
quantity of the crude or raw metal or material (which may be pig-iron in the
manufacture of steel) to a molten state in a furnace or vessel of any suitable
construction. We then introduce into this molten metal or material a quantity of
pure metal or material obtained or reduced by electricity. The reduction of the
pure metal or material, which is preferably malleable iron when steel is being

or vessel containing the molten crude metal or material and then passing through
it a current of electricity generated by a dynamo or in any other well known
manner. The heat generated by the passage of the electric current through the
pure metal or material reduces it and the pure molten metal thus produced is
dropped, put, or conducted, into the furnace or vessel containing the molten crude
metal or material and is mixed therewith. By the addition of the pure molten
metal or material the percentage of carbon and other elements in the combined
mass can be regulated to suit the requirements for which the metal is to be used.
The crude metal or material may, if desired, be first reduced in a furnace and
then run into a mixing vessel or pot into which the pure metal or material reduced
by electricity is introduced.
Although we have described methods whereby our process can be put into
practical operation we do not confine ourselves thereto as any other suitable method
or methods may be employed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we hereby declare that
what we claim is:-
The improved process of manufacturing iron and steel, substantially as herein-
before described.
