Improvements in Cartridges.
I, JAMES GEORGE ACCLES of the Gatling Gun Works, Perry Bar, Birmingham,
in the County of Warwick, Engineer, do hereby declare the nature of this invention
to be as follows:-
Cartridges as at present made are generally provided with a head or flange at
their rear end over which the extractor hooks. This flange abuts against the rear
end of the barrel so that the metal of the gun barrel has to be cut away to receive
the front end of the extractor. The barrel is thereby weakened and it sometimes
happens that it bulges in consequence.
According to my invention 1 make the head at the rear end of the cartridge
double, providing two flanges instead of one as has heretofore been the practice. The
foremost of these two flanges abuts against the rear end of the barrel in the usual
way whilst the other flange over which the extractor hooks; is outside the barrel, so
that the metal of the barrel either need not be cut away at all to receive the extractor
or is cut to a very much less extent than heretofore.

Improvements in Cartridges.
I, JAMES GEORGE ACCLES, of the Gatling Gun Works, Perry Bar, Birmingham,
in the County of Warwick, 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 :-
Cartridges as at present made are generally provided with a head or flange at
their rear end over which the extractor hooks. This flange abuts against the rear
end of the barrel so that the metal of the gun barrel has to be cut away to receive
the front end of the extractor. The barrel is thereby weakened and it sometimes
happens that it bulges in consequence.
According to my invention 1 make the head at the rear end of the cartridge
double, providing two flanges instead of one as has heretofore been the practice.
The foremost of these two Hanges abuts against the rear end of the barrel in the
usual way whilst the other flange over which the extractor hooks is outside the barrel,
so that the metal of the barrel either need not be cut away at all to receive the
extractor or needs to be cut to a very much less extent than heretofore.
The annexed drawing shews a cartridge made in accordance with my invention;
its head has two flanges a and b. The flange a as heretofore limits the distance which
the cartridge enters into the barrel but the extractor does not engage with it as is the
case at present.
The additional flange is provided for the extractor, the nose of which enters the
groove between the two flanges and catches upon the front of the flange b so that
when the extractor recedes from the barrel it carries back the cartridge case with it.
The additional flange comes so far in rear of the breech end of the barrel that the
nose of the extractor can enter the groove in front of it without its being necessary
to cut away the metal of the barrel to allow the extractor to pass.
Or if in some
cases it is convenient to notch the end of the barrel to receive the extractor a much
shallower recess than it is now the practice to provide will suffice.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to he performed 1 declare that what I
claim is --
A cartridge substantially as described with a doubly flanged head and a groove
between the flanges one flange serving to stop the further entrance of the cartridge
into the barrel and the other to be taken hold of by the extractor for the withdrawal
of the cartridge case from the barrel.
