My Invention relates to re-cappable cartridge cases or shells of the kind described
in the Specification of Letters Patent No. 1270 dated 29th January 1885 granted
to me the present Applicant, and my present Invention has for its object to so con-
struct or form the cases' or 'shells that the outer part or cap-piece is prevented from
"accidentally coming off the inner part or case whilst it can readily, be removed
when necessary.

According to my present Invention a screw-indent or thread is made in both the
outer part or cap piece and' the inner part or case by which the said parts are
secured firmly together as far as longitudinal strain and movement is concerned
but when the outer part or cap piece is to be removed from or replaced on the inner
part or case for recapping or other purpose this is readily effected by a screwing or
twisting movement; or instead of a screw any other convenient form of locking
joint which will attain the same object may be employed; for example there may
be a bayonet joint groove or grooves in one part and a projection or projections on
the other part to engage therewith. The indents may be made by a suitable tool
after the cartridge case is put together (or after it is loaded). The cartridge case
may be loaded with a charge by the breech end which could not in the case of a
bottle shaped cartridge be loaded by the neck, and the cartridge can then be put
together and the indents be made, if they have not been made before. "In order to
prevent the fastening when stamped from the metal itself from being flattened out
and the joint destroyed by the force of the explosion we may put in the base of the
inner part or case or shell at the part where the said fastening is formed a wad or
'filling of paper or other material, the interior preferably taking the form of a hollow
cond and
and having a firing hole made through its base."

I BRYAN GEORGE DAVIES COOKE of Colomendy near Mold North Wales Esquire
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 cartridge cases or shells of the kind described in the
Specification of Letters Patent No. 1270 granted to me and dated 29th January
1885 and my present Invention has for its object to so construct or form the cases
or shells that the outer part or cap piece is prevented from accidentally coming off
the inner part or case whilst it can readily be removed when necessary.
According to my present Invention a screw indent or thread is made in both the
outer part or cap piece and the inner part or case by which the said parts are
secured firmly together as far as longitudinal strain and movement is concerned but
when the outer part or cap piece is to be removed from or replaced on the inner
part or case for recapping or other purpose this is readily effected by a screwing or
twisting movement: or instead of a screw any other convenient form of locking
joint which will attain the same object may be employed: for example there may
be a bayonet joint groove or grooves in one part and a projection or projections on
the other part to engage therewith. The indents may be made by a suitable tool
after the cartridge case is put together (or after it is loaded). The cartridge case
may be loaded with a charge by the breech end which could not in the case of a
bottle shaped cartridge be loaded by the neck and the cartridge can then be put
together and the indents be made if they have not been made before. In order to
prevent the fastening when stamped from the metal itself from being flattened out
and the joint destroyed by the force of the explosion I may put in the base of the
inner part or case or shell at the part where the said fastening is formed a wad or
filling of paper or other material, the interior preferably taking the form of a hollow
cone and having a firing hole made through its base.
And in order that the Invention may be properly understood I will describe
with reference to the accompanying drawings ways in which it may be carried
into practical effect premising that I do not limit myself to the precise details shown
as they may be varied without departing from the nature of my Invention.
A suitable joint is shewn in figures 1 and 2 representing the two parts a and b
separately The base part b has an indent in it forming a screw thread or part of
a screw thread and the part a has a similar indent made in it to correspond.
Figures 8 and 4 are similar views shewing bayonet joint grooves in the part a and
bayonet joint projections on the part b. There may be one of these joints or there
may be two on opposite sides of the case.
The indents may be made by a suitable tool after the cartridge case is put to-
gether. This cartridge case may be loaded from the breech if desired and when
the body part is not closed at the end I may use a loose anvil and a loose cap or a
loose piece forming anvil and cap in one. Figure 5 is a section of the part a shew-
ing a wad or piece d of paper or other material which covers the indents which
form the fastening and prevents the said indents from being flattened and destroyed

page_text: by the explosion or otherwise. This wad piece d may be of any suitable shape,
As shewn it has a firing hole through its base. The example here shewn illustrates
a modification wherein the base part b fits into the body part a instead of over it.
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
First In cartridge cases of the kind herein before referred to a screw or bayonet
joint or analogous fastening for the purpose of securing the base or cap piece and
the body part against accidental separation by longitudinal movement or strain
substantially as hereinbefore described.
Second-In cartridge cases of the kind claimed by the preceding claiming clause a
wad or filling piece to preserve the fastening of the parts from being flattened out
or destroyed substantially as hereinbefore described.
