I, RICHARD MORRIS of 42 Bennett Park, Blackheath in the County of Kent,
Engineer, do hereby declare the nature of my invention for "BREECH TUBE FOR
ADAPTING FIRE ARMS FOR MINIATURE AMMUNITION" to be as follows:-
-
In practising aiming, sighting and drill with fire arms, the cost of ammunition
and the necessary length of range are objectionable. It is therefore desirable to
fit into the charge chamber of the ordinary rifle or fire arm a breech tube suited to
receive a cartridge smaller than usual, the expenditure of ammunition and the
extent of range being thus considerably lessened, whilst the practice remains the
same as with ammunition of the usual or service kind. My invention relates to
the construction and mode of fitting and holding in the barrel of a fire arin a breech
tube suited for miniature ammunition. For this purpose I prepare the breech
tube, boring and turning it approximately to its finished dimensions, and then, by
a fine saw cut, slit it along one side, and spring the edges of the saw cut together
holding them by clamps or uniting them by solder; 1 then finish the boring and
turning to the exact dimensions required, and release the clamps or melt the solder,
whereupon the tube springs a little open. When it is pushed into the charge.
chamber, the slit becomes closed and there is sufficient spring to hold the tube.
firmly in its place, while miniature cartridges are introduced, fired and extracted.

same is to be performed, to be particularly described and ascertained in and by the
following statement:-
In practising aiming, sighting and drill with fire arms, the cost of ammunition
and the necessary length of range are objectionable. It is therefore desirable to
fit into the charge chamber of the ordinary rifle or fire arm a breech tube suited
to receive a cartridge smaller than usual, the expenditure of ammunition and the
extent of range being thus considerably lessened whilst the practice remains the
same as with ammunition of the usual or service kind. My invention relates to
the construction and mode of fitting and holding in the barrel of a fire arm a breech
tube suited for miniature ammunition. For this purpose I prepare the breech
tube, boring and turning it approximately to its finished dimensions, and then, by
a fine saw cut, slit it along one side, as shewn in side and end views Figs. 1 and 2.
I then spring the edges of the saw cut together holding them by clamps or uniting
them by solder. While they are so held I finish the boring and turning to the
exact dimensions required, and then release the clamps or melt the solder, where-
upon the tube springs a little open. When it is pushed into the charge chamber
the slit becomes closed and there is sufficient spring to hold the tube firmly in its
place, while miniature cartridges are introduced, fired and extracted.
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
.
.
The herein described construction of breech tube for adapting fire arms for
miniature ammunition.
