PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Armour Plates, and in
Apparatus therefor.
I, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Lanark, North Britain, Steel Manufacturer and Forge Master, do hereby declare
the nature of this invention to be as follows, that is to say:-
My said invention has for its object to improve, simplify, and cheapen the manu-
facture of armour plates.
In carrying out my invention I have steel of any suitable quality or variety cast
in the form of an ingot or slab of the requisite weight and form; and after it has
sufficiently set I transfer it by means of a crane or cranes to a heating furnace
constructed for heating the ingot or slab in a vertical position, and in a uniform
manner throughout its mass.
With one heating I have the mass of steel completely formed into an armour
plate, leaving only the finishing of the edges for subsequent treatment.
The heated mass of steel is transferred from the furnace by a crane or cranes to
a rolling mill having in connection with it driven rollers for conveying the mass
to and from the rolls; and the mass is turned down upon the rollers by means of
suitable mechanism, and is passed through the rolls as often as is necessary to
reduce it to the proper thickness.
From the rolling mill the mass of steel is transferred by a crane or cranes to
apparatus by means of which the required curvature is given to it. This apparatus
comprises a massive iron bed plate of a suitable size and having its upper surface
shaped to the intended curvature. The mass of steel, still in a highly heated state,
is laid upon the bed plate or mould, and then a heavy roller is moved along upon
it from end to end as often as may be required to press it down until it is
throughout in contact with the mould and has thereby had the desired shape
imparted to it. When the shape shows curvature in cross section the roller is
shaped with a corresponding counterpart curvature.
Dated this Twenty-first day of April 1891.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Armour Plates, and in
Apparatus therefor.
I, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Lanark, North Britain, Steel Manufacturer and Forge Master, 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, that is to
Bay :-
My said invention has for its object to improve, simplify, and cheapen the manu-
facture of armour plates.
In carrying out my invention I have steel of any suitable quality or variety cast
in the form of an ingot or slab of the requisite weight and form; and after it has
sufficiently set I transfer it by means of a crane or cranes to a heating furnace
constructed for heating the ingot or slab in a vertical position, and in a uniform
manner throughout its mass.

page_text: With one heating I have the mass of steel completely formed into an armour
plate, leaving only the finishing of the edges for subsequent treatment.
The heated mass of steel is transferred from the furnace by a crane or cranes to
a rolling mill of the ordinary kind having in connection with it driven rollers for
conveying the mass to and from the rolls; and the mass is turned down upon the
rollers by means of suitable mechanism, and is passed through the rolls as often as
is necessary to reduce it to the proper thickness.
From the rolling mill the mass of steel is transferred by a crane or cranes to
apparatus by means of which the required curvature is given to it, and of
which apparatus an example is shown on an accompanying sheet of explanatory
drawings.
Figure, 1, is a plan, Figure, 2, is a side elevation, and Figure, 3, is a transverse
vertical section.
The apparatus comprises a massive iron bedplate, A, of a suitable size and
having its upper surface shaped to the intended curvature. The mass of steel, B,
still in a highly heated state, is laid upon the bedplate or mould, A, and then a
heavy roller, C, is moved along upon it from end to end as often as may be
required to press it down until it is throughout in contact with the mould and has
thereby had the desired shape imparted to it. When the shape shows curvature
in cross section the roller is shaped with a corresponding counterpart curvature as
shown in Figure, 3. In some cases a longitudinal section will show curvature, and
in some cases curvature will be shown in both longitudinal and transverse sections.
The roller, C, may be drawn along the plate, B, by means of chains connected to
a frame, D, fitted to the journals of the roller shaft or axle, and actuated by
hydraulic apparatus or in any other convenient way.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The making of an armour plate with a single heating of the metal, a suitably
heated ingot or slab being rolled to the required thickness, and shaped upon a
mould plate by the action of a heavy roller moved over it substantially as herein-
before described.
2. The shaping of an armour plate by laying it in a suitably heated state
on a mould plate and moving on it a heavy roller substantially as hereinbefore
described.
