PROVISIONAL SPECIFICATION.
Improvements in Apparatus to be used in the Manufacture of
Armour Plates.
I, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Glasgow, 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 obtain increased uniformity in the surface
hardening of armour plates when the hardening is effected by applying water or
other liquid to one or both surfaces of a plate in a suitably heated condition. My
improved apparatus is also arranged so that the hardening operation can be effected
conveniently and expeditiously.
In carrying out my invention I cause the water to be projected upon the armour
plate in films or sheets instead of in detached jets, and I have a to and fro' move-
ment imparted at right angles to the sheets or films so that every part of the
surface of the armour plate will in turn be subjected to the direct impact of the
water.
In a convenient modification of apparatus for projecting films or sheets of water
on the upper surface of an armour plate-there are two water boxes mounted on
wheels to run on lateral overhead rails, these boxes being brought together
over an armour plate as soon as it has been placed in position for being hardened.
Each water box, which is constructed preferably of steel or wrought iron, is made
with two or more internal compartments in order to equalise the distribution of
the water; and the bottom and top are formed of augularly corrugated plates,
the corrugations or ridges running transversely. Slits are formed along the
projecting ridges of the bottom of the box, and water being supplied to the
box under suitable pressure through flexible or jointed pipe connections, issues
from the slits in films or sheets. When the two boxes have been brought
together and connected for an operation they are made to reciprocate longi-
tudinally to about the extent of the distance between two corrugations, by means
of connecting rods moved by cranks or eccentrics on a rotating shaft driven at a
suitable speed.
If it is desired to chill the underside of an armour plate in a similar manner,
similar water boxes are arranged in suitable positions. Slits are formed in the
projecting ridges of the tops of the boxes so as to direct the films or sheets of
water upwards against the underside of the armour plate; and the boxes are made
to reciprocate in the same manner as the upper boxes.

Improvements in Apparatus to be used in the Manufacture of
Armour Plates.
I, WILLIAM BEARDMORE, of Parkhead Forge, Parkhead, in the County of
Glasgow, 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 say :-
My said invention has for its object to obtain increased uniformity in the surface
hardening of armour plates when the bardening is effected by applying water or
other liquid to one or both surfaces of a plate in a suitably heated condition. My
improved apparatus is also arranged so that the hardening operation can be effected
conveniently and expeditiously.
In carrying out my invention I cause the water to be projected upon the armour
plate in films or sheets instead of in detached jets, and I have a to and fro move-
ment imparted at right angles to the sheets or films so that every part of the
surface of the armour plate will in turn be subjected to the direct impact of the
water.
In a convenient modification of apparatus for projecting films or sheets of water
on the upper surface of an armour plate there are two water boxes mounted on
wheels to run on lateral overhead rails, these boxes being brought together over
an armour plate as soon as it has been placed in position for being hardened.
Each water box which is constructed preferably of steel or wrought iron is made
with two or more internal compartments in order to equalise the distribution of
the water; and the bottom and top are formed of angularly corrugated plates,
the corrugations or ridges running transversely. Slits are formed along the pro-
jecting ridges of the bottom of the box and water supplied to the box under
suitable pressure through flexible or jointed pipe connections, issues from the slits
in films or sheets. When the two boxes have been brought together and connected
for an operation they are made to reciprocate longitudinally to about the extent of
the distance between two corrugations, by means of connecting rods moved by
cranks or eccentrics on a rotating shaft driven at a suitable speed.
If it is desired to chill the underside of an armour plate in a similar manner
similar boxes are arranged in suitable positions.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append two sheets of explanatory drawings, to
be hereinafter referred to, and showing my improved apparatus.
Figure, 1, on Sheet, 1, of the drawings is a plan of the apparatus with one
upper-surface water box removed. Figure, 2, is a sectional side elevation of the
apparatus.
Figure, 3, on Sheet, 2, is a plan, and Figures, 4, and 5, are vertical sections as
at right angles to each other, of a part of an under-surface water box, drawn to a
larger scale.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
For projecting films or sheets of water on the upper surface of an armour plate,
there are two water boxes, A, and, B, mounted on wheels, C, to run on lateral
overhead rails which are carried by girders, T, supported on vertical columns, V,
these boxes being brought together over an armour plate as soon as it has been
placed in position in a chamber, W, for being hardened. Each water box, A, B,
which is constructed preferably of steel or wrought iron, is made with four internal
compartments in order to equalise the distribution of the water; and the bottom and
top are formed of angularly corrugated plates, the corrugations or ridges running

page_text: transversely. Slits, D, are formed along the projecting ridges of the bottom of the box,
and water supplied to the box, under suitable pressure through flexible or jointed
pipe connections, E, issues from the slits in films or sheets. When the two boxes, A,
and B, have been brought together, and connected for an operation (which may be
done in any convenient way) they are made to reciprocate longitudinally to about
the extent of the distance between two corrugations, by means of eccentrics
rods, G, connected to eccentrics, H, on a rotating shaft, J, driven at a suitable
speed; or the boxes may be made to reciprocate by means of connecting rods
moved by cranks on a rotating shaft. On the end of the shaft, J, for driving it
there is a worm wheel, K, into which there gears a worm, L, on a shaft, M, driven
by means of a pulley, N, on it.
The figures also show apparatus for chilling the underside of an armour plate in
a similar manner, similar but stationary water boxes, P, and Q, being arranged in
suitable positions. Slits, D, are formed in the projecting ridges of the tops of the
boxes so as to direct the films or sheets of water (supplied by pipe connections, R,
to the boxes) upwards against the underside of an armour plate. Or instead of
the lower water boxes, P, Q, being stationary they may be made to reciprocate in
the same manner as the upper boxes.
Having now particularly described and ascertained the nature of my sail
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In the manufacture of armour plates, the chilling of either or both surfaces
of a plate by water or other liquid projected thereon in sheets or films, in
the manner and by means of apparatus substantially such as are hereinbefore
described.
2. In the manufacture of armour plates, and when chilling either or both
surfaces of a plate with sheets or films of water or other liquid, arranging the
apparatus to move the sheets or films to and fro' substantially as and for the
purposes hereinbefore described.
