I JOSEF SCHULHOF of 3 Schwindgasse, Vienna, in the Empire of Austria
Engineer do hereby declare the nature of this invention to be as follows:-
The object of this invention is the construction of a cartridge shell without the
projecting rim heretofore in use in all cartridges. Instead of said projecting rim
this cartridge is at, or near its end provided with a groove around its circumference
which forms a sharp or straight edge in the rear part of the cartridge for the
purpose of permitting the extractor to grip and hold it. The object of having a
projecting rim in the old cartridges was to prevent the cartridge when fired from
being drawn into the chamber. In this improved cartridge I attain this object
by inserting into the forward part of the cartridge a small tube, ring or
ferule of metal into which fits the projectile. This tube, ring or ferule gives
additional surface to the front edge of the cartridge, by means of which the said
cartridge abuts against the forward shoulder of the chamber in the rifle barrel and
is thus prevented from entering any further into it when the shot is fired.

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 this Invention is the construction of a cartridge, which having no
projecting rim, is specially suited for use in magazine fire arms.
A cartridge of this kind is shown in the annexed drawing in which Fig. 1
represents a side view of the cartridge Fig. 2 a like view partly in section. Fig. 3
is a cross section of the cartridge and bullet. Fig. 4 is a longitudinal central section
through the cartridge shell.
As seen by the drawing this cartridge has instead of the common bottle shape
the form of an even cylinders slightly tapering towards its front or bullet end.
Its principal differences from other cartridges however is that its rear end does
not form a rim projecting beyond the largest diameter of the cartridge shell. The
projecting rim in the old cartridges served two purposes, firstly to prevent the
cartridgo from entering the chamber of the barrel any deeper than required, secondly
to permit the extraction of the emptied shell by means of the extractor. In this new
cartridge provision is to be made of the latter circumstance as will be shown further
below.
To provide a place for the grip of the extractor the cartridge bottom (which is
shown in figure 4 is rather thicker than common) is by turning or pressing provided
with a circular groove or notch a sharp and straight at the rear and tapering
forward so as to be fit for receiving and retaining the nose or claw of the cartridge
extractor.
To prevent the cartridge from being pushed or forced by the shot too far into the
barrel chamber and even into the rifled part of the barrel, which would prevent the
extraction, a metal ring or ferrule bushing b, is inserted in the front end of
the cartridge and into this ferrule the projectile c. fits. By this construction the
difference of diameter between the projectile and the cartridge itself at its forward
end naturally becomes much greater than is commonly the case and the barrel chamber
having to be bored out correspondingly at its forward end offers a much broader
shoulder, against which abuts the front end of the cartridge (figure 3) sufficiently to
prevent from entering any further than required into the barrel.
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 :—
Firstly—In cartridge shells an annular notch a at or near their rear end, serving

page_text: the purpose of the projecting rim in other cartridges, substantially as described and
shown in the annexed drawing.
Secondly In cartridges the application of a ring or ferrule (bushing) 6 in the
forward end into which ring or bushing fits the projectile c, substantially as and for
the purpose herein set forth and shown by the drawings.
