An Improved Machine for Decapping and Recapping Cartridges.
I, FRANCIS JAMES COCKS of Shipton Mush Wenlock in the County of Salop,
Farmer do hereby declare the nature of my said invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
My invention has for its object an improved machine for capping and recapping
cartridges which enables the cases to be used several times as they inay be decapped
and recapped at leisure and thus a considerable saving is effected in a very simple
manner.
In order that my invention may be clearly understood, and more easily carried
into practice I have appended hereunto a double sized sheet of drawings upon
which I have illustrated several modes of carrying my invention into effect.
Figure 1. is a vertical sectional elevation through one of my machines shewn in
the position in which a cartridge is being capped or recapped.
Figure 2. is a similar section to Figure 1 but shewing the machine in the position
when the decapping is being effected.
Figure 3 is an external view of the machine shewn in Figures 1 and 2.
Figure 4 is a sectional elevation shewing a modification of my machine.
Figure 5 is an end elevation of the head to the lever support in Figure 4.
Figure 6 is a sectional elevation shewing another modification of my machine.
Figure 7 is a plan of figure 6.
Referring to Figures 1 2 & 3 upon the base A which may be of wood metal or
other suitable material I mount the sliding block a¹ which may be of dovetail shape
or square as may be desired, and which is made to slide a limited distance which
is determined by the adjustable stop a².
Immediately above this and upon the supports 62 I fix the block B
which the
upon
cartridge D fits the block B being made to screw on to the base so as to be
interchangable for different sizes of cartridges. Within this block I provide the
sliding rod or plunger E having at the top the needle e¹ which needle is mounted or
formed to operate under the cap d' of the cartridge D its normal position being to
remain down either by its own weight or by the assistance of a spring. The under
slide is provided with the incline slot or recess a³ upon which the base of the sliding
plunger E works so that when the slide A is moved backwards or forwards the
plunger E and needle e¹ rises or falls. The vertical lever H is mounted on the
centre which is attached to the outer casing K and is connected at its lower end
by means of the link 2 to the sliding block a¹ and is provided at the top with the
horizontal lever M having the solid swell m¹ for pressing down and capping or
recapping the cartridge by means of the handle m³ as shewn by Figure 1 as also
the hollow swell m² for decapping the cartridge as shewn by Figure 2 where it will
be noticed that the action of drawing this hollow swell m² over the cap of the
cartridge also draws the sliding block a until the plunger E is raised by the incline a³
to the position in which the cap d' is forced out of the cartridge D into the recess in
the swell m² while the cartridge is pressed down by the swell m² on the lever M
as shewn at Figure 2. The outer casing or ferrule K assist in guiding the
cartridge and keeps it central upon the block or dummy B. For recapping the
cartridge the lever is removed and pressed back until the swell m' is over the
centre of the cartridge which also brings forward the sliding block a' and
allows the plunger E and needle e' to fall thereby allowing of a fresh cap being placed
in the hole and driven home by the swell m¹ as shewn at Figure 1.
Any form of spring such: for instance as N may be used for operating the sliding

page_text: block a¹ in either direction and the machine may be attached to the table X by any
convenient means such as shewn by the cramp Y in figures 1 and 2.
In the case of the modification shewn in Figures 4 and 5 I mount the lever m³ so
as to revolve in the socket 'm³ which is in turn pivoted at me in the forked head p¹ of
the upright P which is fixed to the base A so that the swell m' and hollow swell m²
are so placed that by revolving the lever M either may be turned down for operation
upon the cap in which case the inclined sliding block a' would be operated by the
rod a* and spring a³.
In the case of the modification shewn by Figures 6 and 7 I mount the dummie or
block B upon the plate B2 which is made to slide upon the base A in the clips 6³ so
that by means of the hinged lever R or other arrangement the centre of the
cartridge D may be brought either under the hollow swell'm² as shewn or the solid
swell m in the latter case the plunger E would fall into the inclined recess a which
is formed in the stationary block a¹ so as to allow of the cap d' being forced home by
the swell m¹ on the lever M5 which is hinged to the supports S at me. The tops of
the blocks B may be made to screw off so as to allow of the plunger E being readily
taken out for a fresh needle to be inserted.
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 :-
