Improvements Applied to Cartridges for Fire Arms.
I EDOUARD DE BEAUMONT, of Rue du Fossé, Maestricht, in the Kingdom of
Holland, Manufacturer of Fire Arms, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements applied to cartridges for fire arms and
it cousists particularly in the combination of a flange, reduced to the fraction of a
millimeter, with an annular groove formed in the base in front of the flange.
The ordinary cartridges intended for repeating fire arms have several defects:
the flange cartridges are easily extracted from the chamber, but have the defect of
only giving packages or bundles of irregular form, packing with difficulty the one
upon the other and leaving important vacant spaces between them further, the
greatly projecting flanges of the ordinary cartridges often occasion a wedging of
the cartridges in the magazine or in the loader; the cartridges without flange, with
annular groove, or flange countersunk in the base, have the defect of being seized
with difficulty by the cartridge-retractor; the extraction is therefore defective;
further, these cartridges not being stopped by a flange have the defect of entering
too far into the chamber, so that the cartridge-retractor can no longer seize them.
This defect arises from a slight difference, a decrease in the dimensions of the
cartridge, or a little wear of the chamber.
The object of this invention is to remedy these defects. For this purpose, the
flange of the cartridge case (shown on the accompanying drawing to a multiple
scale) is reduced to its minimum, a fraction of a millimeter in projection on the
cylindrical part of the case, and to ensure the proper working of the cartridge-
retractor, an annular groove is made in the base immediately in front of the flange.
Thus the bundles or packages of cartridges are nearly rectangular and the cartridges
may be casily packed with a minimum loss of space; the Hanges cannot cause a
wedging of the cartridges in the magazine or in the loader and, nevertheless, they
prevent the cartridges entering too far into the chamber; further, the extraction is
effected as easily as in the case of the ordinary flange cartridges.

and ascertained in and by the following statement :-
This invention relates to improvements applied to cartridges for fire arms and it
consists particularly in the combination of a flange, reduced to the fraction of a
millimeter, with an annular groove formed in the base in front of the flange.
The ordinary cartridges intended for repeating firearms have several defects: the
Hange cartridges are easily extracted from the chamber, but have the defect of only

further, these cartridges not being stopped by a flange have the defect of

of the cartridge, or a little wear of the chamber.

The object of this invention is to remedy these defects. For this purpose, the
flange of the cartridge case (shown on the drawing left with the Provisional
Specification drawn to a multiple scale) is reduced to its minimum, a fraction of a
millimeter in projection on the cylindrical part of the case, and to ensure the proper
working of the cartridge-retractor, an annular groove is made in the base
immediately in front of the flange. Thus the bundles or packages of cartridges are
nearly rectangular and the cartridges may be easily packed with a minimum loss of
space; the flanges cannot cause a wedging of the cartridges in the magazine or in
the loader and, nevertheless, they prevent the cartridges entering too far into
the chamber; further, the extraction is effected as easily as in the case of the
ordinary flange cartridges.
Having now 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 :-
In metallic cartridges: the combination of a flange reduced to the fraction of a
millimeter with an annular groove formed in the base, in front of this flange
substantially as described.
