I, RICHARD MORRIS, of Bennet Park, Blackheath in the County of Kent,
Engineer do hereby declare the nature of my invention for "BREECH PIECE OR
TUBE AND APPLIANCE FOR ADAPTING FIRE ARMS FOR MINIATURE AMMUNITION
to be as follows:-
"
It is often desirable to practice aiming, sighting and drill with fire arms of
ordinary size but firing miniature ammunition so that the practice can be carried
on at small ranges and little expense. In some of the methods employed for this
purpose it has been usual to insert into the charge chamber of the fire arm a
tubular breech piece having a small bore to suit miniature cartridges, and this
breech piece has to be withdrawn by the extractor after every discharge so as to
clear it of the spent cartridge case, an operation which occupies time and interferes
with drill. Now, according to my invention, I make the breech tube without a
flange for the extractor to act upon it, and form it with an external circular groove
in which I wind a number of convolutions of thread served with cobbler's wax or
such like adhesive and somewhat yielding substance. I push this piece into the
breech of the fire arm where it remains securely held, and I employ such cartridges
as have flanges broad enough to be acted on by the extractor. When it is
required to remove the breech tube, I insert from the breech a strip of metal bent
to the form of an elongated U having at the ends of its limbs externally
projecting lips which, when they pass beyond the mouth of the breech tube, spring
out and catch over the edge of that mouth. Then introducing a ramrod or other
rod by the muzzle to reach down to the breech, a blow serves to dislodge the
breech tube, which can then be removed.

I, RICHARD MORRIS of Bennet 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 :-

It is often desirable to practice aiming, sighting and drill with fire arms of
ordinary size but firing miniature ammunition, so that the practice can be carried
on at small ranges and little expense. In some of the methods employed for this
purpose, it has been usual to insert into the charge chamber of the fire arm a
tubular breech piece, having a small bore to suit miniature cartridges, and this
breech piece has to be withdrawn by the extractor after every discharge so as to
clear it of the spent cartridge case, an operation which occupies time and interferes
with drill. Now, according to my invention, I make the breech tube without a
Hange for the extractor to act upon it and form it with an external circular groove
in which I wind a number of convolutions of thread served with cobblers' wax or
such like adhesive and somewhat yielding substance. I push this piece into the
breech of the fire arm where it remains securely held, and I employ such cartridges
as have flanges broad enough to be acted on by the extractor. When it is
required to remove the breech tube, I insert from the breech a strip of metal bent
to the form of an elongated U having at the ends of its limbs externally projecting
lips which, when they pass beyond the mouth of the breech tube, spring out and
catch over the edge of the mouth. Then, introducing a ramrod or other rod by the
muzzle to reach down to the breech, a blow serves to dislodge the breech tube,
which can then be removed.
Fig. 1 of the accompanying drawings is a longitudinal section of the breech
tube A having within it the spring tool B for withdrawing it from the breech.
Fig. 2 is an external elevation of the breech tube, which is recessed externally as
shewn at C to receive the thread packing, for which, as in pistons, might be
substituted a divided spring ring. The tool B for extracting the breech tube
consists of a strip of metal bent to form a pair of spring jaws which carry at their
ends pieces of metal D, such as gun metal, softer than the metal of the tube A.
This tool is inserted from the breech till the pieces D pass the front edge of the
tube A when they spring apart overlapping the edge. A rod E having on it a
boss F is then introduced from the muzzle and by the pressure of the boss F against
the pieces D, aided if necessary by a smart blow, the breech tube is forced out at
the breecb. The coned nipple e, extending beyond F into the space between the
pieces D, prevents them from collapsing when they are subjected to the pressure or
blow.

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. The breech piece or tube A provided with packing C.
2. The spring tool B for driving out the breech tube.
