COMPLETE SPECIFICATION.
Improvements in Cartridges for Sporting Guns
I MAX SCHEUERBRANDT of Neustädber Kirchstrasse 13, Berlin, in the Empire
of Germany, Lithographer, do hereby declare the nature of my said invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The disc of paste-board or paper-pulp hitherto employed for closing up or
sealing the outer ends of the cartridges used for sporting guns has had the effect
of diminishing the striking efficiency of the shots when fired owing to its having
to be first displaced by the shots and thereby causing them to be too much
scattered & deviating them from their original path or direction and reducing their
striking power by increasing the resistance of the air.
The object of this invention is to remedy these defects by substituting for the
said disc a metal ferrule or cap.
And in order that this invention may be more readily understood and carried into
practical effect I have hereunto annexed a sheet of drawings and will now proceed
to describe the same with the assistance of the various figures and letters of
reference marked thereon.
Fig. 1 is a longitudinal section and Fig. 2 a plan of a cartridge having my
improved cap shewn applied thereto.
Fig. 3 is a detail view of my improved cap or ferrule.
In accordance with my invention the cartridge case A is made of paper-pulp
the lower part of which is formed in the same way as the ordinary paste board
cartridges whilst the upper end is furnished with a screw thread on to which a
thin soft metal cap B is capable of fitting similarly screw threaded (see Fig. 3)
and which cap is tightly screwed thereon and cannot become detached therefrom.
The cartridge case A is filled in the ordinary way and the cap subsequently screwed
thereon. To now ensure that the shots shall retain their full striking power and
thus attain the desired object the underside of the improved cap is not formed as of
an uniform surface but is cut through into segments of a circle by radial slits as
illustrated more clearly in Fig. 2.
When the cartridge is fired these segments are separated and fly outwards (see
Fig. 4) and the shots meeting no resistance rush onward with undiminished
force.
It is obviously not necessary that the cap B should be screwed upon the cartridge
case A as the same may be shrunk or forced on (as illustrated in Fig. 5) or firmly
affixed thereto in any other suitable manner.
The cap B may be formed as a ring with segmental prongs projecting outwards
and forming a crown like edge (see Fig. 5) which is only bent over after the cartridge
has been filled.
Having thus 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 :-
1st. The improved metal closing device characterized by a metal cap or ferrule B
capable of being screwed or otherwise affixed on the prepared end of the cartridge
case A and provided with radial slits (see Figs. 1 and 2) substantially as and for
purposes hereinbefore described and illustrated on the accompanying drawing.
2nd. The improved metal closing device characterized by a metal ring B shrunk
forced or otherwise affixed on the end of the cartridge case A and provided with
the

page_text: segmental prongs capable of being turned down (see Figs. 5 & 6) substantially as
and for the purposes hereinbefore described & illustrated on the accompanying
drawing.
