PROVISIONAL SPECIFICATION.
Improvements in Shot Cases for Air and such like Guns.
I, JOSEPH ELTON BOTT of Eyam in the County of Derby, Metallurgist, do
hereby, declare the nature of this invention to be as follows:-
The invention has for its object improvements in shot cases for air and such like
guns whereby such cases are capable of being used as ordinary cartridges that is to
say they can be inserted at the breech of a gun and being provided with, a rim or
flange they can when spent be extracted by the ordinary extractor.
My improved shot case is formed in a similar manner to ordinary cartridge cases
except that the rear end has a comparatively large hole in the centre thereof; in
charging these cases with shot a wad is first fitted in the bottom and is supported
upon the annular rear end of the case, the shot is then placed in the case and
another wad is placed in the fore end thereof so as to retain the shot therein.
When the shot case is placed in the breech of the gun, the latter closed and a
charge of compressed air or gas admitted to the gun, the air or gas passes through
the open rear end of the shot case and exerting its pressure upon the rear wad
forces both wads and shot out of the case and gun leaving the case behind which is
then extracted in the ordinary manner and by the usual means.

COMPLETE SPECIFICATION.
Improvements in Shot Cases for Air and such like Guns.
1, JOSEPH ELTON BOTT, of Eyam in the County of Derby, Metallurgist, 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:-
The invention has for its object improvements in shot cases for air and such like
guns, whereby such cases are capable of being used as ordinary cartridges, that is
to say, they can be inserted at the breech of a gun and, being provided with a rim
or flange, they can, when spent, be extracted by the ordinary extractor.
My improved shot case is formed in a similar manner to ordinary cartridge cases,
except that the rear end has a comparatively large hole in the centre thereof; in
charging these cases with shot, a wad is first fitted in the bottom and is supported
upon the annular rear end of the case, the shot is then placed in the case, and another
wad is placed in the fore end thereof, so as to retain the shot therein.
And in order that my said invention may be more clearly understood, and readily
carried into effect, I will proceed, aided by the accompanying drawings, more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section, and
Figure 2 is a rear view, of a shot case, constructed according to my invention, for
use with air and such like guns.
a is the cylindrical portion or body of my improved shot case, which is provided at
its rear end with a rim b, in a similar manner to ordinary cartridge cases, except that
[Price 6d.]

page_text: the rear end has a comparatively langeliole in the centre thereof; in charging these
cases with shot, a wad d is first fitted in the bottom or rear end of the case, and it
is supported upon the annular rear end of the case, so as to close the hole c therein,
as shown in the drawing; the shot e is then placed in the case, and another wad / is
placed in the fore end.thereof, so as to retain the.shot.e therein.
When the shot case is placed in the breech of the gun, the latter is closed, and a
charge of compressed air or gas admitted to the gun; the air or gas passes through
the opening in the rear end of the shot case and, exerting its' pressure upon the
rear wad d, forces both wads d and y' and shot e' out of the case and gun, leaving the
case behind, which is then extracted from the gun-in. the ordinary..manner and by
the usual means employed to extract an ordinary: spent cartridge case fromrthe
breech end of a gun.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is, to be performed, I declare that, what I
claim is :-
:-
1. A shot case, for air and such like guns, constructed substantially as herein
shown and described.
2. In shot cases-for-air and such like guns, the combination with a cylindrical
body, having a rim at its rear end, of a comparatively large hole in such rear end,
a wad resting against 'the annular rear end, and a wad at the fore end to retain the
shot' within the case, substantially as herein'shown and described.
