Improvements in the Manufacture of Cartridge-cases.
I, ANTON REINISCH of Erdbergerstrasse 53, Vienna, Austria, Manufacturer of
Cartridges, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of cartridge-cases which are formed of
two parts both of which are manufactured of a particular material hereinafter
described.
The cartridge-case is manufactured from a pulp prepared from cordage, that is to
say, a pulp made of ship's ropes or rope ends; is treated in the way usual in
making tough paper from such material. It is first cut into small pieces then
ground, washed and again treated in a pulping machine. The pulp obtained is mixed
with five per cent. of its own weight of a solution of starch. The mixture is then
suitable for the manufacture of the cartride cases.
Without departing from the nature of this invention I may add any of the following
materials to the cordage when an inferior quality of cartridge cases is to be manufac-
tured viz. linen, cotton, hemp, jute, sulphite-celulose, white or brown wood pulp,
straw pulp, fine or coarse packing rags or other rags, twine refuse, spinning refuse,
cording refuse, cotton wool, animal hairs, vegetable fibres, gypsum, chalk, potatoes,
mealy pulpy substances, such as paste, gluten, glue and the like.
For forming the head of the cartridge the pulp prepared as above described is put
into a steel or other metal mould. The moulds consist of a base and a cylindrical
part into which a stamp or die is forced by suitable pressure.
The said die may be suitably engraved with any design or letters representing the
quality of the cartridge-case, its calibre, the name of the maker or the like. The
pulp which is poured into the mould is subjected to a pressure of about a ton and
the expressed liquid passes out through holes suitably arranged in the lower part of
the mould. For forming the tube of the case the pulp is put into a mould similar to
that above described except that it is provided with a long core. The stamp or die is
made tubular and fits between the said core and the circular part of the mould.
The cartridge tubes are then well dried and finally polished with agate and the
heads are well dried, then dipped into an oil bath and immediately taken out and well
baked for about two hours in an oven at a temperature of about 50 to 60 degrees
Centigrade which causes them to become about as hard as bone. The head is finally
coated with a bronze paint giving it the appearance of brass.
The manufacture of the cartridge case is completed by applying liquid glue to the
cartridge head and then inserting it into the tube and finally drying it.
The cartridge cases manufactured as above described have the following advantages.
1. The tube being cast and not made of rolled paper is of uniform strength and not
liable to split in firing.
2. The head is of less weight than a metal head and does not oxidize or cause
oxidation, as it does not contain metallic or corrosive materials.
3. The gun is not liable to injury through friction in using such cartridges as there
is no friction of metal against metal.
4. The cartridge case being about as hard as bone, it resists injurious influences of
weather and does not suffer from exposure to wet.
5. The cartridge cases are much cheaper than those hitherto made.

page_text: This invention relates to the manufacture of cartridge cases which are formed
of two parts, both of which are manufactured from a particular material hereinafter
described.
In the accompanying drawing,
Figure 1, shows a central fire cartridge case, and
Figure 2 a pin-fire cartridge-case made according to the present invention.
Figures 3 and 4 show the moulds for forming the different parts of the cartridge
case.
A is the tubular part of the cartridge case, B is the head provided with the flange b
and with the chamber c into which the priming cap is inserted.
According to the present invention the cartridge case is manufactured from pulp
prepared from cordage, that is to say a pulp made of ships ropes or rope ends. This
pulp is treated in the way usual in making tough paper from such material by
being first cut into small pieces, then ground, washed and again treated in a
pulping machine. The pulp obtained is mixed with five per cent. of its own
weight of a solution of starch. The mixture is then suitable for the manufacture
of the cartridge cases:
When it is desired to manufacture an inferior quality of cartridge case I may add
any of the following materials to the above mentioned mixture, viz. :-linen, cotton,
hemp, jute, sulphite-cellulose, white or brown wood-pulp, straw pulp, fine or coarse
packing rags or other rags, twine refuse, spinning refuse, cording refuse, cotton wool,
animal hair, vegetable fibres, gypsum, chalk, potatoes, mealy pulpy substances, such
as paste, gluten, glue, and the like.
For forming the head B of the cartridge case the pulp prepared as above described
is put into a mould G of steel or other suitable metal as shown in Figure 3 and for
forming the tube portion A the said pulp is put into the mould G₁ as shown in
Figure 4. Each of these moulds consist of a base E or E¹ a middle cylindrical
part G or G and a stamp or die H or H¹ which is forced by suitable pressure into
the said cylindrical part G or G¹. The end of the die H may be suitably engraved
with any design or letters representing the quality of the cartridge case, its calibre,
the name of the maker or the like. The pulp which is poured into the mould is sub-
jected to a pressure of about one ton and the expressed liquid passes out through holes g
suitably arranged in the lower part of the said mould. For forming the tube or
cylindrical part of the cartridge case the pulp is forced into the mould shown in
Figure 4 which is similar to that above described except that it is provided with a
long core E¹. The stamp or die H¹ is made of tubular form and fits between the said
core and the mould G¹. The cartridge tubes A thus made are then well dried and
finally polished with agate and the heads B are also well dried, then dipped into an
oil bath and immediately taken out and well baked for about two hours in an
oven at a temperature of about 50 to 60 degrees Centigrade which causes them
to become about as hard as bone. The said head is finally coated with a paint
which gives it the appearance of brass. The tnbe A is then connected to the
head B by applying glue to the said head B and then inserting it into the said
tube A and finally drying it.
The cartridge cases manufactured as above described has the following advantages.
1. The tube A being moulded and not made of rolled paper is of uniform strength
and not liable to split in firing.
2. The head B is of less weight than a metal head and does not oxidize or cause
oxidation, as it does not contain metal or corrosive materials.

page_text: 3. The gun is not liable to injury through friction in using such cartridges as there
is no friction of metal against metal.
4. The cartridge case being about as hard as bone resists the injurious influences
of weather or of moisture and the like.
5. The cartridge cases are much cheaper than those hitherto used.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what I
claim is :-
First. A cartridge case manufactured from pulp made from cordage with or without
the admixture of the above named substances, the said cartridge case consisting of a
tube A and head B substantially as described and as shown in the drawing.
Second. The manufacture of cartridge cases substantially as above described and as
shown in the drawing.
