A CARTRIDGE PROTECTOR to be as follows:
Year: 1885

page_text: I, THORSTEN NORDENFELT of 53 Parliament Street in the City of Westminster
Civil Engineer do hereby declare the nature of my invention for "A CARTRIDGE
PROTECTOR to be as follows:-
"
The object of my invention is to provide an instrument to protect a cartridge
from premature explosion. In the case of cartridges of large dimensions, especially,
there is risk of explosion when the cartridge is accidentally dropped as the cap in
the base of the cartridge may come in contact with a projecting point, as for
example a small pebble or anything of a nature to indent the cap.
To avoid this danger I apply to the cartridge the protector which I will now
proceed to describe and this protector is intended to remain on the cartridge until
it is to be placed in the gun or gun hopper.
My cartridge protector consists of a piece of brass or other suitable material
formed with clamps so arranged at their ends as to fit tightly over the rim of the
cartridge case and to admit of easy removal. In the centre of the protector I form
a cup into which I insert a piece of india rubber or other elastic substance. The
elastic material covers the cup and takes any sudden blow which otherwise might
fall upon it thereby protecting the cap from explosion by accidental blows in
transport.
'
The piece of india rubber or other soft substance can be temporarily attached by
other like means.

Civil 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 :-
The object of my invention is to provide an instrument to protect a cartridge
from premature explosion. In the case of cartridges of large dimensions especially
there is risk of explosion when the cartridge is accidentally dropped as the
percussion cap in the base of the cartridge may come in contact with a projecting
point as for example a small pebble or anything of a nature to indent the cap.
To avoid this danger I apply to the cartridge the protector which I will now
proceed to describe and this protector or safety clip is meant to remain on the
cartridge until it is to be placed in the gun or gun hopper.
My cartridge protector is made of brass or other suitable material and it is
formed with clamps so arranged at their ends as to fit tightly over the rim of the
cartridge case and to admit of easy removal.
In the centre of this safety clip I form a cup into which I insert a piece of india
rubber or felt or other elastic substance.
This elastic material fills the cup and takes up any sudden blow which otherwise
might fall upon it thereby protecting the cartridge from explosion by accidental
blows on the percussion cap during transport.
This piece of india rubber or felt or other soft substance can also be fixed over
the percussion cap of the cartridge by means of wires passing to the rim of the
cartridge and there secured in any convenient manner or by other means the piece
or pad of india rubber or felt or other soft substance may be temporarily fixed over
the percussion cap of the cartridge.
The cartridge protector as I prefer to construct it is. represented in the annexed
drawings It is a safety clip and Figure 1 represents in plan this safety clip.
Figure 2 is a side elevation partly in section of the same. Figures 3 and 4 are
plan and side elevations showing the safety clip in position.
a is the cup which contains the disc of india rubber or felt or other soft
substance. b are the arms or clamps which serve to secure it to the cartridge case-
these are bent at their ends as shown in Figure 2 in order to get a good hold of
the rim of the cartridge. The safety clip is put on by pressing it down by
hand and it can easily be removed by hand to prepare the cartridge for imme-
diate use.

page_text: 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
(1.) A cartridge protector consisting of a piece or pad of india rubber felt or
other soft substance temporarily attached to the cartridge and protecting it from
premature explosion by covering its percussion cap substantially as described.
(2.) A cartridge protector consisting of a cover or cup placed over the percussion
cap of the cartridge and there temporarily secured by arms passing to the rim of
the cartridge substantially as described.
(3.) A cartridge protector or safety clip substantially as above described.
