PROVISIONAL SPECIFICATION.
An Appliance for Adapting Quick Firing and Machine Guns to be
used with 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:-
-
My invention relates to an appliance by which I adapt quick firing or machine
guns to be used with miniature ammunition, that is to say with projectiles and
explosive charges considerably less than those ordinarily used in these guns. For
this purpose, I provide a strong tube bored to the calibre of the miniature ammuni-
tion and I fix this tube centrally in the bore of the machine gun in the following
manner. On the front part of the tube I fix a boss or collar, which is turned to fit
the bore of the machine gun or which can be made with conically expanded segments,
and on the breech end of the tube I fix a flange which for part of its width in front
is turned to fit the bore, and for the rear part of its width is turned to the same size
as the flange of the service cartridge usually employed for the gun. I insert the
tube from the breech sliding its front boss along the bore until the flange at the
rear comes to seat itself in the recess which is formed to receive the flange of
the service cartridge. The breech block of the gun being then brought to bear
against the flange at the end of the tube, holds the tube firmly in position.

COMPLETE SPECIFICATION.
An Appliance for Adapting Quick Firing and Machine Guns to be
used with Miniature Ammunition.
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 an appliance by which I adapt quick firing or machine
guns to be used with miniature ammunition, that is to say with projectiles and
explosive charges considerably less than those ordinarily used in these guns. For
this purpose as shown in longitudinal section by the accompanying drawing I
provide a strong tube A bored to the calibre of the miniature ammunition B and I
fix this tube centrally in the bore of the machine gun C in the following manner.
On the front part of the tube I fix a boss or collar D which is turned to fit the bore
of the machine gun or which can be made with conically expanded segments as
described in my former Specifications No. 9356 of 1885 and No. 3244 of 1886 and
on the breech end of the tube I fix a flange E which for part of its width in front
is turned to fit the bore, and for the rear part of its width is turned at F to a lip of
the same size as the flange of the service cartridge usually employed for the gun.
I insert the tube A from the breech sliding its front boss D along the bore until
the lip F at the rear comes to seat itself in the recess which is formed to receive
the flange of the service cartridge. The breech block G of the gun being then
brought to bear against the flange F holds the tube A firmly in position. In order
to prevent the tube from being disturbed by the ordinary extractor when the
breech block G is removed, I cut off part of the lip F at a place corresponding with
the position of the extractor.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
In combination with a quick firing machine gun, a tube A suited for miniature
ammunition, held in the bore by its boss or collar D and flange E with lip F
substantially as and for the purpose set forth.
