We THE CHECK-MARKING TARGET SYNDICATE LIMITED of 20 Tyndale
Place Islington in the County of London and WILLIAM EDWIN HEATH of
3 Canonbury Square Islington aforesaid, Major (retired) do hereby declare the
nature of this invention to be as follows:-
This invention is intended more especially for application to cartridges which
are to contain a small charge of powder and are to be used for purposes of
practice.
The cartridge case is, according to this invention, made in parts divided trans-
versely and provided with screw or other means whereby they can be readily
secured together and separated. For example the rear end of the front part may
be provided with a male screw terminating in or carrying the nipple to receive the
percussion cap or detonator and the fore end of the hinder part be provided with
an internal or female screw which on being screwed on the screw of the front part
forms the complete cartridge case. There is a hole in the base of the hinder part
to allow the striking pin of the fire arm to explode the cap or detonator.
the case has been used it is extracted from the fire arm (for which purpose it may
be provided with the usual rim at the base) and by unscrewing or separating the
parts of the case it can be readily recapped. The nipple part can be readily
renewed when worn without need for renewing the case as a whole.

We THE CHECK MARKING TARGET SYNDICATE LIMITED of 20 Tyndale
Place Islington in the County of London and WILLIAM EDWIN HEATH of
3 Canonbury Square Islington aforesaid Major (retired) 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 invention is intended more especially for application to cartridges which
are to contain a small charge of powder and are to be used for purposes of
practice.
The cartridge case is according to this invention made in parts divided trans-
versely and provided with screw or other means whereby they can be readily
secured together and separated.
The accompanying drawing illustrates in elevation in Figure 1 and in longitudinal
section in Figure 2 a cartridge case made in accordance with this invention in what
we consider the best form.
Figure 3 shews the hinder part separately in side and end views.
Figure 4 shews the rear end of the front part separately and
Figure 5 shews the front part separately without the rear end thereof.
In the example here shewn the rear end of the front part A is provided with a
male screw a terminating in or carrying the nipple a² to receive the percussion cap
or detonator and the fore end of the hinder part B is provided with an internal or
female screw b which on being screwed on the screw a of the front part A forms

case has been used it is extracted from the firearm (for which purpose it may be
provided with the usual rim cat the base) and by unscrewing or separating the
parts of the case it can be readily recapped. The meeting faces at x are preferably
somewhat coned as shewn. The nipple part can be readily renewed when worn
without need for renewing the case as a whole. For this purpose the screw a
may be made separate from the part A and be screwed or otherwise secured
thereinto.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A cartridge case made in parts or divided transversely and provided with a
screw or other means whereby they can be secured together and separated for
recapping or other purpose substantially as herein before described.
2. A cartridge case made of a front part A provided with a separable screwed
nipple piece a a² and a back part B to screw thereonto and having a hole therein
for the striking pin of the firearm to act on the cap or detonator substantially as
hereinbefore described and illustrated in the accompanying drawing.
