JAMES DIXON Cornish Place Sheffield in the County of York Gun Implement
and Electroplate Manufacturer, and GEORGE SIMPSON 19 Highton Street Walkley
Sheffield in the County of York, aforesaid, Gun Implement Maker, do hereby
declare the nature of the said invention for AN IMPROVED METHOD OF CLOSING
BREECH LOADING CARTRIDGE CASES to be as follows:-
The invention, consists in the improved method of gripping the base of any
breech loading cartridge case by means of a Clutch-Cam-Lever or Handle, and a
cylinder (serrated or otherwise upon its inner side), and at the same time causing
the said cylinder containing the said cartridge case, to revolve within a second
cylinder whilst closing the end of the cartridge case for the purpose of retaining
the charge in its proper position.
The clutch-cam-lever or handle and the cylinder are necessary in order to prevent
the brass rim or flange of the cartridge case being damaged or cut whilst the
cartridge is being gripped and caused to revolve upon its own axis. To attain this
we construct a revolving. cylinder the internal diameter of which is slightly larger
than the external diameter of the cartridge case. To the outer end of this
cylinder we fix a semi-circular collar (serrated or otherwise upon its inner side),
the edge being swaged off so as to permit the rim or flange of the cartridge case to
sink below the edge of the collar. Upon the side of the cylinder, at the point
where the collar terminates, we fix an action-boss, to the side face of which we
fasten by means of a stout screw, bolt, or revit the clutch-cam-lever or handle.
The cam may be fixed upon the inner side, upon the centre upon the edge, or
upon the end of the lever or handle, and is countersunk upon its face, so that the
rim or flange of the cartridge case shall not be damaged whilst the cam is being
made to grip the side of the said case.
The revolving cylinder with the clutch-cam-lever or handle attached is fitted
into a second cylinder fixed upon a stand (or any suitable apparatus for closing the
cartridge) and held in position by means of a collar of brass (or any other suitable
netal) screw'd upon the nose of the said revolving cylinder.

the cartridge passing within the swage of the semi-circular collar attached to the
end of the said inner cylinder. The inner cylinder is now made to revolve by
means of the cam-lever or handle with an initial motion from left to right. The
act of causing the said cylinder to revolve forces the said cam-lever or handle to
pass over the base of the cartridge case, and the cam to grip the side of the said
cartridge case, thus causing it to revolve along with the inner cylinder to the
end that the mouth of the said cartridge may be closed by means of any suitable
apparatus.

We, JAMES DIXON of Cornish Place Sheffield in the County of York, Gun
Implement and Electro-plate Manufacturer, and GEORGE SIMPSON of 19 Highton
Street, Walkley, Sheffield, in the County of York aforesaid, Gun Implement maker
do hereby declare the nature of our invention for AN IMPROVED METHOD OF
CLOSING BREECH LOADING CARTRIDGE CASES and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The Invention, consists in the improved method of gripping the base of any
breech loading cartridge case, by means of a Clutch Cam Lever or Handle, and a
cylinder (serrated or otherwise upon its inner side), and at the same time causing
tlie said cylinder containing the said cartridge case, to revolve within a second
cylinder whilst closing the end of the cartridge case for the purpose of retaining
the charge in its proper position.
The Clutch Cam Lever or Handle (Fig. 1) and the cylinder (Fig. 2, A) are
necessary in order to prevent the brass rim or flange of the cartridge case Fig. 3. N.
being damaged or cut, whilst the cartridge Fig. 3. is being gripped and caused to
revolve upon its own axis. To attain this, we construct a revolving cylinder
Fig. 2. A. the internal diameter of which is slightly larger than the external
diameter of the cartridge case Fig. 3. To the outer end of this cylinder Fig. 2 A.
we fix a semicircular collar Fig. 2 B. (serrated or otherwise upon its inner side), the
edge B" Fig. 2 B. being swaged off so as to permit the rim of the cartridge case to
sink below the edge of the collar. Upon the side of the cylinder (Fig. 2. A.) at the
point where the collar terminates we fix an action boss C. Figs 2 & 5. to the side
face of which we fasten by means of a stout screw, (Fig. 5 G) bolt, or rivet, the
clutch cam lever or handle Fig. 1. The cam may be fixed upon the inner side,
Fig. 1, upon the centre, Fig. 1 A, upon the edge, Fig. 1 B. or upon the end, Fig. 1. C.
of the lever or handle, and is countersunk upon its face K. Figs. 4 & 5. so that the
rin of the cartridge case Fig. 3 N, shall not be damaged whilst the cam being
made to grip the side of the said case Fig. 3. O.
The revolving cylinder with the clutch cam lever or handle attached is fitted
into a second cylinder, E. Figs. 2. & 5. fixed upon a stand (or any suitable
apparatus for closing the cartridge) and held in position by means of a collar of
brass, D. Figs. 2 & 5. (or any other suitable metal) screw'd upon the nose Fig. 2
A" A" of the said revolving cylinder.
The cartridge Fig. 3 is inserted at the end of the inner or revolving cylinder the
rim of the cartridge Fig. 3 N passing within the swage B" Figs. 2 & 5. of the
semicircular collar B. Figs. 2 & 5. attached to the end of the said inner cylinder A
Fig 2. & 5. The inner cylinder is now made to revolve by means of the cam
lever or handle H. Figs. & 6. with an initial motion from left to right Fig. 6.
The act of causing the said cylinder to revolve forces the said cam lever or
handle H. Figs. 5 & 6, to pass over the base of the cartridge case Fig. 6. M. and

page_text: the cam I. Figs. 5 & 6 to grip the side Fig. 3. O. of the said cartridge case thus
causing it to revolve
alue along with the inner cylinder to the end that the mouth of
the cartridge Fig. 3. P. may be closed by means of any suitable apparatus.
the cartridge Fig. 3. P. may be closed by means of any suitable apparatus.

Having now particularly described our Invention and the manner in which the
same is to be performed, we wish it to be understood that we claim :-
:-
The use of the clutch cam lever for gripping (without the aid of a spring) from
the inner side, from the centre, from the edge or from the end of the lever, any
part of the sides of a cartridge case, whilst the said cartridge case is being made to
revolve upon its own axis in the manner and for the purposes substantially as
hereinbefore described and shewn in the drawings.
