PROVISIONAL SPECIFICATION.
Improvements in Ammunition for Pneumatic Guns, Pistols, and
the like.
BERNARD RODWELL BANKS of 22 Elgin Road Addiscombe Croydon Engineer,
do hereby declare the nature of this invention to be as follows:-
it
This my invention relates to ammunition for air & other guns and is a method
of making suitable shot charges for the same. In carrying out this my invention
I employ a case shell, or cylinder of any suitable material metal or otherwise and
of suitable size according to the bore of the gun. The said case shell or cylinder
is flanged at one end sufficient to prevent its passing through the barrel & to render
casy of abstraction. At the flanged or rim end of the said case shell or cylinder
I make a circular hole slightly smaller than the diameter of the cylinder, I then
place a wad, disc or cup of any suitable material inside the cylinder and covering
this hole, I then fill the cylinder with shot of a suitable size and cover the top with
any suitable material to retain the shot. The shot charge is then ready for use.
The action is, the shot charge is inserted in the breech of the gun and the action
of the discharge forces the wads and shot from the case, the shot scattering in
the usual way, leaving the case in the gun which can be ejected as desired.
Dated this Second day of October 1894.

COMPLETE SPECIFICATION.
Improvements in Ammunition for Pneumatic Guns, Pistols, and
the like:
BERNARD RODWELL BANKS of 22 Elgin Road Croydon 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:-
This my invention relates to improved shot charges for pneumatic and similar
guns. In carrying out this my invention I employ a case shell or cylinder of any
suitable material metal or otherwise and of suitable size according to the bore of
the guns. The said case, shell or cylinder has an annular outer flange at one end.
sufficient to prevent its passing through the barrel and to render it easy to extract
after the charge is projected. At the flanged or rim end of the said case shell'or
cylinder I make a circular or any other convenient aperture slightly smaller than
the inside diameter of the cylinder I then place a wad, disc or cup of any suitable
material inside the cylinder and covering the aperture I then fill the cylinder
with a charge of shot of any suitable size or substance and cover the top with any
suitable material to retain the shot.
In order that my invention may be more readily understood reference should be
made to the accompanying drawings in which,
Figure I is a section of the completed shot charge and casing for the same.
Fig. II is a plan thereof.
A Fig. I is the aperture. B the outer flange C the case or shell, D wads for
the top and bottom E the charge of shot and F the inside shoulder forming a
seating for the wad D.
It will be readily understood that the charge being inserted in the breech of the

page_text: gun, the air pressure on being liberated will expel the wads and shot by means of
the aperture at the back of the shell, leaving the shell in the gun. The shells if
of suitable material may be recharged and used over & over again.
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
I. A casing comprising a cylindrical shell having a central opening therethrough
and means for retaining said shell within a gun barrel after its charge has been
expelled substantially as set forth.
=
11. A cartridge casing of any material comprising a cylindrical shell having a
central bore therethrough, an annular flange round one end of the said casing and
an annular shoulder within the said casing substantially as set forth.
III. In a shot charge or cartridge a combination of a cylindrical shell having a
central opening therethrough an annular flange around one end of the said shell, an
annular shoulder formed within the said shell and a suitable charge coutained
within the said casing substantially as set forth and illustrated in the accompanying
drawings.
Dated this Tenth day of November 1894.
