Improvements in the Manufacture of Projectiles for Piercing
Armour Plates and the like.
I, ALBERT REANEY, Edge Tool Manufacturer, 160 Devonshire Street, Sheffield,
Yorkshire do hereby declare the nature of this invention to be as follows:-
I take an Ingot of Iron & Steel of a suitable section, or all Steel, and after heating
place the piece between a pair of longitudinal Dies, bringing the Dies together with
force I so elongate and form the nose or tapered end of a Projectile. If preferable I
take a piece large enough to produce two Forgings by placing the center of the heated
picce directly under a cutting Tool of special formation which is brought to bear
upon it untill the piece is devided, this operation giving a tapered nose or end to each
piece.
I next proceed with a novel and highly important process viz. by placing the piece
to be punched in a solid Die, or devided Dies the two parts of which may be opened
and closed by any suitable means, The Forging is encased and held in an upright
position while a punch or drift is driven vertically down the center forming the hollow
or chamber required in Shells, and during the same operation embossing the material
with great force against the Walls of the Die, giving a much desired equality and
great density.
The Punch which I devise for forming the chamber of the Shell is so fixed in the
Tup of the Power or Steam Hammer as to allow of a vertical movement. This
important action is as follows, the piece of hot material being placed in the Die, and
the Hammer set to work the point of the punch rests for an instant on the center of
the material, untill the face of the descending Tup or Hammer Head comes in contact
with the Head of the Punch, which drives the Punch down into the hot metal; The
contraction of the hot metal upon the cool Punch would be difficult to overcome if a
fixed Punch were employed, but as the Tup moves upwards without raising the Punch

page_text: until the bottom of the recess strikes the underside of the Punch Head a sharp blow
is given to the Punch, which instantly releases it from the material, and this enables
a succession of rapid blows to be given.
To finish the operation I then place the Punched Forging Nose upwards, and by
means of suitable Dies, Hammer and give greater density to the piercing end of the
Projectile, by this process of equable Forging, I am enabled to ensure greater
certainty in Hardening.

I, ALBERT REANEY No. 1 Sheaf Gardens Sheffield Edge Tool 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:
I take an ingot of steel of a suitable section and after heating place the piece
between a pair of longitudinal dies bringing the dies together with force, I so elongate
and form the nose or tapered end of a projectile, If preferable I take a piece large
enough to produce two forgings by placing the centre of the heated piece directly
under the cutting tool A of special formation which is brought to bear upon it until
the piece is divided, this operation giving a tapered nose or end to each piece.
.
I next proceed with a novel and highly important process, viz.:-by placing the
piece to be punched in either a solid B or divided C dies the two parts of which may
be opened by any suitable means, the forging D is encased or held in an upright
position while a punch E or drift is driven vertically down the centre forming the
hollow or chamber required in shells and also during the same operation embossing
the material with great force against the walls of the die giving a much desired
equality and great density.
The Punch which I devise for forming the chamber of the shell is so fixed in the
tup of the hammer as to allow of a vertical movement. This important action is as
follows-the piece of hot material being placed in the die and the steam or power
hammer set to work the point of the punch rests for a monent on the centre of the
material until the face of the descending tup or hammer head F comes in contact
with the head of the punch G which drives it into the hot metal.
The contraction of the hot metal on the cool punch would be difficult to overcome
if a fixed punch were employed, but as the tup moves upward without raising the
punch until the bottom of the recess H strikes the underside of the punch head a
sharp blow is given to the punch which instantly releases it from the material and
this enables a rapid succession of blows to be given.
To finish the operation I then place the punched forging nose upwards and by
means of suitable dies hammer and give a greater density to the piercing end of the
projectile. I am thus enabled to ensure greater density and greater certainty in
hardening.

page_text: 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 :-
No. 1. That I form an ingot of steel into suitable forms for making a Projectile.
No. 2. That by my specially constructed punch as described I form the opening or
chamber required in a shell.
No. 3. That by the operations of forging and punching of the shell in the dies 1
secure favourable condition for hardening the shells equally.
