PROVISIONAL SPECIFICATION.
Improvements in Projectiles for Ordnance and Fire Arms.
I, RICHARD MORRIS, of Bennett Park, Blackheath, in the County of Kent,
Engineer, do hereby declare the nature of this invention to be as follows:-
-
My invention relates to the construction of a projectile with a base part so
arranged as to take the rifling and operate as a gas check. For large bore or
machine guns I form the long conoidally headed body of the projectile preferably
of steel with a shank of smaller diameter projecting at the rear. On this shank I
place a ring of softer metal such as brass having its front edge turned in as a flange
fitting the shank, while the rest of the ring being larger than the shank leaves_an
annular space around the shank. Into this annular space 1 compress lead or alloy
or other soft metal and, in order to prevent it from becoming displaced, I prefer to
cut on the shank a screw thread or circular grooves into which the soft metal is
pressed.
For small arms, I make the body of the projectile of lead or alloy with a shank
of smaller diameter. On this shank 1 put the flanged ring and I then compress the
shank endways until it tightly fills the body of the ring.
When the projectile is fired, the brass ring being somewhat swelled out by the
pressure of the powder gas takes the rifling and operates as a gas check.
In some
cases, more especially when small charges are to be fired, the ring may be made in
the first instance of an external diameter a little larger than the body of the
projectile so that it, instead of the body of the projectile, may take the rifling.
When the projectile is of considerable length I prefer to put two rings on the
shank, one some distance in front of the other, with a filling of soft metal between
them. Or by making the projectile with a shank projecting each way from its
body, I can put the one ring on the front shank and the other on the rear shank
and compress both shanks endways by one operation.

Improvements in Projectiles for Ordnance and Fire Arms.
I, RICHARD MORRIS, of Bennett Park, Blackheath, in the County of Kent,
Engineer, 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 :-
My invention relates to the construction of a projectile with a base part so
arranged as to take the rifling and operate as a gas check. For large bore or
machine guns I form the long conoidally headed body of the projectile preferably
of steel with a shank of smaller diameter projecting at the rear. On this shank I
place a ring of softer metal such as brass having its front edge turned in as a flange
fitting the shank, while the rest of the ring being larger than the shank leaves an
annular space around the shank. Into this annular space I compress lead or alloy
or other soft metal and, in order to prevent it from becoming displaced, I prefer to
cut on the shank a screw thread or circular grooves into which the soft metal is
pressed.
For small arms, I make the body of the projectile of lead or alloy with a shank
of smaller diameter. On this shank I put the flanged ring and I then compress the
shank endways until it tightly fills the body of the ring.

page_text: When the projectile is fired, the brass ring being somewhat swelled out by the
pressure of the powder gas takes the rifling and operates as a gas check. In some
cases, more especially when small charges are to he fired, the ring may be made in
the first instance of an external diameter a little larger than the body of the
projectile so that it, instead of the body of the projectile, may take the rilling.
When the projectile is of considerable length I prefer to put two rings on the
shank, one some distance in front of the other, with a filling of soft metal between
them. Or by making the projectile with a slank projecting each way from its
body, can put the one ring on the front shank and the other on the rear shank
and compress both shanks end ways by one operation.
Fig. of the accompanying drawings is a longitudinal section of a projectile
according to my invention suited for large bore or machine guns.
The conoidal boly B which is preferably of steel is made with a shank which
may be serew threaded or may be circularly grooved as shown. On this shank I
place a ring R of softer metal such as brass having in front of it an internal
Hange fitting on the shank S. In the annular space between the shank S and the
ring compress lead or other soft metal or alloy L which is presented
from being displaced by engaging with the grooves or screw thread of the shank S.
For small arms as shown in Fig. 21 make the holy B and shank S in one piece of
lead or alloy, I place the ring R on the shank and then by pressure I upset the
shank so as to fill up the interior of the ring as shown in Fig. 3. Fig. 4-how the
body B made with iwo shanks S and S to receive respectively a rear ring R and a
front ring R. The two shanks are then upset by pressure, the rear shank filling
in the ring and the front shank filling in the ring R and forming the convidal
head as shown in the side view Fig. J.
-
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A projectile for large hore or machine guns consisting of a hard metal body
with a shank on which a soft metal internally flanged ring is held by lead or like
metal compressed into the space between it and the shank, substantially as described
with reference to Fig. 1.
2. A projectile for small arms consisting of a body and shank of lead or alloy
having an internally flanged ring fixed on the shauk by upsetting the shank within
it, substantially as described with reference to Figs. 2 and 3.
3. A projectile for small arms consisting of a body with front and rear shanks of
lead or alloy having internally flanged rings fixed on these shanks by upsetting the
metal thereof, substantially as described with reference to Figs. 4 and 5.
