Improvements in Cartridge De-cappers and Re-cappers.
We ALFRED CAUSER 11 Court 2 House New Summer Street in the City of
Birmingham, Gun Implement Maker and HENRY ARTHUR WARD of Russell Street
in the City of Birmingham aforesaid Gun Maker do hereby declare the nature of this
invention to be as follows:
This invention relates to a combined instrument or apparatus for the recapping
and also for the extracting of the spent caps of central fire breech loading
cartridges.
Usually a separate instrument or apparatus is employed for each size of cartridge
or cartridge case to be recapped or the spent cap thereof to be extracted.
Our invention has for its object, the employment of one instrument only for
the recapping and cap extracting as aforesaid of any size cartridge or cartridge case,
and this we accomplish by providing the middle of the top of the lifting pillar, with a
conical recess.
In carrying out our invention, in respect to the cap extracting means, we employ
a lifting shell-liko pillar, working and sliding upon the extracting pillar, in manner,
that an extracting needle, directed upwardly from the middle of the top of the said
extracting pillar, passes through a hole in the middle of the top of the lifting
pillar, when the same is depressed by the swelled pressure part of a lover, coming
upon it.
The outside entrance to the hole in the top or head of the lifting pillar, as aforesaid,
is coned or taper sunken, to a depth suitable for receiving varying sized cap chambers
or domes of cartridge shells. This coned recessing of the said middle part, compels
a cartridge, whatever the size may be, to centre itself, or to become perfectly central
with respect to the axis of the pillar, so that the extracting needle when unsheathed,
by the pressing down of the lifting pillar, causes the tip of the said needle to pass
through the flash hole of the cap chainber, and then impinge upon the cap, which is
expelled thereby.
It will be thus seen, that by making the recess wherein the cap chamber of a
cartridge unseats itself, when placed upon the pillar, graduated, that whatever size or
guage the cartridge may be, the tapering as aforesaid compels the same to dispose
itself axially, with respect to the pillars and needle.
The lever as aforesaid, is jointed to the upper extremity or summit of a post or
upright, disposed between the aforesaid extracting pillar, and a re-capping pillar
carried upon a base or stand common to both pillars and lever upright.

COMPLETE SPECIFICATION.
Improvements in Cartridge De-cappers and Re-cappers.
We, ALFRED CAUSER 11 Court 2 House New Summer Street in the City of
Birmingham, Gun Implement Maker and HENRY ARTHUR WARD of Russell Street in
the City of Birmingham, Gunmaker, 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:-
This invention relates to a combined instrument or apparatus, for the re-capping,
and de-capping of central-fire cartridge cases.

page_text: Our invention has for its object, the employment of a single instrument, for both
recapping and decapping any sized cartridge, or cartridge case, generally between
10 and 20 guage, but to this we do not limit ourselves, as the means employed, as
hereinafter described, may be so constructed as to comprehend a wider range than the
aforesaid.
Usually, a separate sized decapping pillar, is employed for each size or guage of
cartridge or cartridge case.
Our invention consists primarily, in providing the middle of the top of the
decapping pillar, with a taper or cone sunken recess, which centralizes or draws the
axis of the cartridge case, coincident with the axis of the pillar, whereby the expelling
spike or needle, commonly employed for ejecting, is made central with the flash hole
of the cap chamber, containing the cap.
In carrying out our invention, or one form thereof, in connection with a decapping
pillar, we provide the middle top side of a lifting shell, with a coned sunken recess,
tapering inwards, and we make the said shell, slide upon a fixed stalk, whose upper
end has a spike, or expelling needle, and disposed between the inside top of the said
shell, and the top of the fixed stalk, is a coiled spring, for giving the return movement.
to the said shell, after each and every decapping operation.
This decapping pillar, is supported upon a base, upon which the recapping pillar is
also carried, and between the said pillars, is an upright standard, to the upper end of
which, the operating lever is jointed. This lever has sunken upon one side of it, a
recess, for the freeing of the cap expelled, and the other side, a plain swell, for the
pressing home of the cap, into the cap chamber, upon the recapping pillar.
Figure 1 of the accompanying drawing, represents partly in elevation, and partly
in vertical section, a combined instrument or apparatus, for the re-capping, and
--de-cupping_of_n.central fire cartridge case, with the decapping part, constructed and
arranged according to our invention.
The middle of the head of the lifting shell of the decapping pillar, is shown
provided with a taper sunken hole, whereby the cartridge case to be decapped; is
centralized, by the inside or outside bottom of the cap chamber, taking within the
said coned recess, and drawing the cartridge case thereby, to a central point, to admit
of the ejecting pin or needle, passing up the flash hole of the said chamber, and so
expelling the cap.
Figure 2 represents a like view as Figure 1, but with the lever of the instrument,
depressed, and the spent cap, shown in the act of being expelled, by the forcing down
of the cartridge case, with the lifting shell.
Figure 3 represents the said instrument, in the act of recapping.
Figure 4 represents a longitudinal section of the lifting shell of the decapping
pillar, showing the coned sinking in its head.
Figure 5 is a front elevation of the same, and Figure 6 is a top side plan of the
said lifting shell.
a is the base of the instrument, b is the recapping pillar, and c the decapping
one; the latter consists of a fixed stalk support e, mounted at top by a shoulder c²,
terminated by a spike or needle c³, adapted for expelling a spent cap as herein-
after described. is a lifting shell, sliding upon the fixed supporting stalk c¹, and
provided at its inside top or head end, with a recess c, and a coned sunken middle
part e, whereby the cartridge shell d, is centralized, or drawn to a central point, to
wit the axis of the said decapping pillar.
To give the reaction to the lifting shell, after the lever e, jointed at e², to an
upright bracket e, has been removed from its forcing down position, a coiled
spring is disposed between the supporting stalk c', and the inside head of the lifting
shell.
The bottom of the taper sunken recess c in the middle of the top of the
decapping pillar, or the lifting shell thereof, has a passage c', wherethrough the
expelling spike or needle c³, upwardly passes. The swell part e, of the lever e,
has a recess e, sunken within its underside, when in the position as in Figure 1.
The recapping pillar b, has formed within the middle of its top side, a recess &²,

page_text: wherein the cap chamber of the cartridge, passes or hangs, as shown in
Figure 3.
The decapper lifting shell part, is prevented from rotating upon the fixed and
supporting stalk part, by a screw or stud c8, of the one part, taking within the slot c
of the other part.
ACTION FOR RECAPPING.
Place the cartridge shell upon the pillar b, after previously inserting in the cap
chamber 9, the cap and anvil i, within it. Then turn the lever into the position as
represented in Figure 3, when on pressure being applied to the said lever, the cap is
forced into the cap chamber, flush with the back of the head.
To decap a spent case, place the cartridge shell d upon the decapping pillar, or the
lifting shell thereof, which is raised as in Figure 1, when the said cartridge shell,
centralizes itself, or automatically centralizes itself, by its hanging cap chamber
falling or seating itself centrally within the taper sunken hole or recess e", then turn
the lever into the position as in Figure 1. when the forcing down of the same, causes
the swelled side (with the recesse, formed within it, so that the cap shall clear the
lever) to impinge upon the head of the cartridge, when the said cartridge is forced
vertically downwards with the lifting sholl, the spring within the latter compressed,
hence the passing of the passage c', over the ejecting spike or middle c³, whereby the
spent cap is expelled, by the passage of the flash hole of the cap chamber over the
spike, and the impingement of the anvil upon it.
Although we have described that the taper recess or sunken hole co, is made within
the top of the lifting shell of a yielding decapping pillar, yet we wish it to be
understood that the said part carrying the recess, may be fixed, instead of movable,
as the ejecting spike or needle might be made to rise and fall, instead of being
fixed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
First: In a cartridge decapper, providing the middle of the top with, or sinking
within the middle of the top, of a decapping pillar, (either fixed or movable)
a taper or cone sunken recess, whereby cartridge cases of dissimilar sizes or guages,
are centralized, or automatically centralized, substantially as and for the purpose as
set forth.
Secondly-In a cartridge case recapper, and decapper, with a decapper pillar,
provided with a cone or taper sunken recess or hole, at the middle of its top or upper
end, to centralize or draw the axis of a cartridge case, to the axis of the pillar, sub-
stantially as set forth.
