Miniature Ammunition.
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:-
:-
In my Specification No. 4846 of 1883 I described means of adapting a large gun
for being used with miniature ammunition by fixing within the main barrel a small
bore barrel, and, in the case of a breech loading gun or mitrailleuse as shewn in
Fig. 3 of the drawings, introducing at the breech a block of the shape of the
ordinary cartridge having inserted in it a small or miniaturo cartridge suited to tho
small bore barrel. My present invention relates to special appliances used in con-
nection with apparatus of the kind above referred to, particularly when it is applied
to a quick firing shell gun. As described in my former Specification No. 4846 of
1883 I provide a tubular block corresponding in size and shape with the ordinary
cartridge of the gun, but into the bottom flange at the breech end of this block I
scrow a steel tube which internally has the shape of the charge chamber for the
miniature or small cartridge that is to be used, and which becomes externally reduced
at its front end to a diameter a very little larger than the bore of the small barrel.
The breech end of the small barrel is bored to receive this steel tube, which itself
constitutes a strong charge chamber to hold the miniature or small cartridge. The
operation of the gun with miniature charges is conducted as follows:-
The small barrel is properly centred and fixed within the main barrel by screwing
it into a coned nut which enters into and opens out a divided conical sleeve that fits
within the main barrel; a number of blocks such as are above described are also
provided each having fixed in it the steel charge chamber containing its small
cartridge. One of these charged blocks is inserted at the breech of the gun, its out-
side fitted in the boro of the gun at the breech, while its steel charge chamber enters
into and fits the breech end of the small barrel. The cartridge in this block having
been discharged, the block itself is extracted in the usual way, and a fresh charged
block is introduced, these blocks succeeding each other with the same rapidity as the
ordinary cartridges. From the blocks after their extraction the shells of the spent
cartridges are pushed out by hand, and fresh cartridges are then inserted into their
charge chambers.

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:-
In my Specification No. 4846 of 1883 I described means of adapting a largo gun
for being used with miniature ammunition by fixing within the main barrel a small
bore barrel, and, in the case of a breech loading gun or mitrailleuse as shewn in
Fig. 3 of the drawings, introducing at tho breech a block of the shape of the ordinary
cartridge having inserted in it a small or miniature cartridge suited to the small boro
barrel. My present invention relates to special appliances used in connection with
apparatus of the kind above referred to, particularly when it is applied to a quick
firing shell gun.
Fig. 1 of the accompanying drawings is a longitudinal section of part of the breech
end of a quick firing gun; Fig. 2 is a longitudinal section shewing part of the bore.
farther forward.
As described in my former specification No. 4846 of 1883 I provide a tubular
block N strengthened in front by a ring n, and corresponding in size and shape with
the ordinary cartridge of tho gun, but into the bottom flange M at the breech end of
this block I screw a steel tube L which internally has the shape of the charge chamber
for the miniature or small cartridge that is to be used, and which becomes externally
reduced at its front end to a diameter a very little larger than the bore of the small
barrel. The breech end of the small barrel A is bored to receive the steel tube L,
which itself constitutes a strong charge chamber to hold the miniature or small
cartridge. The operation of the gun with miniature charges is conducted as follows:-
The small barrel A is properly centred and fixed within the main barrel by screwing
its threaded end a into a coned nut B which enters into and opens out a divided
conical sleeve C that fits within the main barrel. This sleeve is split along one side as
indicated at C and as fixed by screws a³ to its end a ring a¹ engaging a collar a on
the small barrel A, another collar on which passes through a plug a placed at the end
of the charge chamber of the main barrel. A number of blocks N such as are above
described are also provided each having fixed in it the steel charge chamber L con-
taining its small cartridge. One of these charged blocks is inserted at the breech of
the gun, its outside N fitting in the bore of the gun at the breech while its steel charge
chamber L enters into and fits the breech end of the small barrel A. The cartridge
in this block having been discharged, the block itself is extracted in the usual way and
a fresh charged block is introduced, these blocks succeeding each other with the same
rapidity as the ordinary cartridges. From the blocks, after their extraction, the shells
of the spent cartridges are pushed out by hand, and fresh cartridges are then inserted
into thin charge chambers, so that they are ready to be used again.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. For adapting breech loading guns for drill and practice with miniature
ammunition, in combination with a small barrel A fixed centrally in the bore of the
gun, tubular blocks N each made with a charge chamber L to receive a small cart-
ridgo and to enter the breech of the small barrel A, substantially as herein described
with reference to Fig. 1.
2. For contoring and fixing the small barrel A in the bore of the gun, the use
in combination therewith of the conical nut B and the split sleove C substantially
as described with reference to Fig. 2.
