CHARLES DENTON ABEL of No 28 Southampton Buildings Chancery Lane, in
the County of Middlesex "IMPROVEMENTS IN SPORTING CARTRIDGE CASES
[Communicated to him from abroad by Wilhelm Lorenz of Carlsruhe in the German
Empire.]
For sporting firearms of all descriptions, in particular for Lancaster and
Lefaucheux guns paper or pasteboard cartridge cases have heretofore mostly been
used, on account of metal cases causing various inconveniences.-Namely while the
outer diameter of metal cartridge cases for the above mentioned guns were made
to correspond with the cartridge seat or chamber of the gun and with the outer
diameter of the pasteboard cases, the inner diameter of the metal cases was too
large, on account of the greater thickness of the pasteboard cases, and for several
reasons it was not practicable to use metal cases of the same thickness as the
cardboard cases. Thus the metal cases contained a greater quantity of powder and
shot and required a larger closing plug than the pasteboard cases, which abnormal
circumstances had a detrimental effect on the behaviour of the gun in shooting.
These inconveniencies are effectually avoided by the present improved metal
cartridge case provided with an outer removeable metal jacket, the outer diameter
of which jacket corresponds accurately with the cartridge seat or chamber of the
gun and with the outer diameter of the pasteboard cartridge cases, while at the
same time the inner diameter of the metal case also corresponds with the inner

page_text: diameter of the pasteboard cases, thus insuring an equal charge of powder and an
equal sized plug.
This description of metal case with double sides can be used with equal advantage
in the same guns constructed for use with pasteboard cases. In using these
improved metal cases the outer jacket remains in the chamber or cartridge seat of
the gun after firing and withdrawing the case, so that only the first cartridge used
requires to have the jacket If it be subsequently desired to shoot with pasteboard
cartridges again, the metal jacket can be readily removed from the chamber with
the fingers.
This arrangement is applicable for all calibres of Lancaster, Lefaucheux, and
other sporting guns

CHARLES DENTON ABEL of No 28 Southampton Buildings, Chancery Lane,
in the County of Middlesex. IMPROVEMENTS IN SPORTING CARTRIDGE CASES
A communication to me from abroad by "Wilhelm Lorenz" of Carlsruhe in the
German Empire.
For sporting firearms of all descriptions, in particular for Lancaster and
Lefaucheux guns, paper or pasteboard cartridge cases have hitherto mostly been
used on account of the metal cases causing various inconveniences. Namely, while
the outer diameter of metal cartridge cases for the above mentioned guns was
made to correspond with the cartridge seat or chamber of the gun and with the
outer diameter of the pasteboard cases, the inner diameter of the metal cases was
too large, on account of the greater thickness of the pasteboard cases, and for
several reasons it was not practicable to use metal cases of the same thickness_as
the cardboard cases. Thus the metal cases contained a greater quantity of powder
and shot and required a larger closing plug than the pasteboard cases which
abnormal circumstances had a detrimental effect, on the behaviour of the gun in
shooting.
These inconveniencies are effectually avoided by the present improved metal
cartridge case provided with an outer removeable metal jacket, the outer diameter
of which jacket, indicated at B, in the accompanying drawings, corresponds
accurately with the cartridge seat or chamber of the gun and with the outer
diameter of the ordinary pasteboard cartridge cases, while at the same time the
inner diameter of the metal case A also corresponds with the inner diameter of the
pasteboard cases, thus insuring an equal charge of powder and an equal sized plug.
Fig 1 of the drawings shews a longitudinal secton of the cartridge case, Fig. 2 shews
an elevation and Fig 3 a plan
This description of metal case with double sides can be used with equal
advantage in the same guns constructed for use with pasteboard cases. In using
these improved metal cases the outer jacket B remains in the chamber or cartridge
seat of the gun after firing and withdrawing the case, so that only the first cartridge
used requires to have the jacket. If it be subsequently desired to shoot with
pasteboard cartridges again, the metal jacket B can be readily removed from the
chamber with the fingers.
This arrangement is applicable for all calibres of Lancaster, Lefaucheux and other
sporting guns,
Having thus described the nature of the said invention and in what manner the
same is to be performed as communicated to me by my foreign correspondent I
claim :-
In sporting cartridge cases the combination of an outer removal metal jacket B
with the metal case A to be used as a substitute for pasteboard cartridge cases in
all descriptions of sporting guns.
In Witness whereof I the said Charles Denton Abel have hereunto set my
hand and seal this seventeenth day of November in the year of our Lord
One thousand eight hundred and eighty two.
