CHARLES EDWARD PERCY GABRIEL, of Moseley, in the County of Worcester,
Managing Clerk. "IMPROVEMENTS IN CREASERS FOR CREASING CARTRIDGES AND
IN APPARATUS FOR CAPPING AND RECAPPING CARTRIDGE CASES."
My Invention relates principally to creasers for producing the creases in
cartridges by which the wad is fixed and the charge retained in the cartridge case.
My Invention further relates to additions to creasers made according to my
Invention, by which additions the creaser may be converted into an apparatus for
capping and recapping cartridge cases.
In constructing a creaser according to my Invention, I mount a cylindrical rod
or mandril vertically on a horizontal base plate, the said base plate having a screw
clamp attached to it, by means of which clamp the creaser is fixed to a table or
support when in use. The said cylindrical rod or mandril is of a size suitable for
the reception of the open end of the cartridge case. On the base plate and
concentric with the mandril described a hollow cylinder is fixed, the interior of
which is of somewhat larger diameter than the mandril. When the cartridge is
placed on the mandril, that portion of the case in which the creasing is to be effected
is situated in the space between the mandril and the hollow cylinder. On the top
of the hollow cylinder is a broad strong flange, and at equi-distant points on the
face of the said flange three radial grooves are made. In these grooves the creasing
tools are situated, and work by sliding towards and from the axis of the mandril.
The upper side of each of the creasing tools carries a peg or projection by which
the motion of the said tools is effected. Upon the flange on the top of the hollow
cylinder a strong cap or cover is situated, the said cap or cover being capable of
rotating through a small angle on the said flange. A handle is fixed on the edge of
the said cap or cover, by means of which handle the cap or cover is turned. In
the under or inner face of the said cap or cover three curved eccentric slots are
made, in which slots the pins or projections on the creasing tools engage. When
the cap or cover is turned in one direction by its handle, the creasing tools are
made to slide inwards in their grooves, and the acting ends of the said tools are
made to protrude in the hollow cylinder. When the handle is turned in the

page_text: opposite direction the creasing tools are moved in the opposite direction, their
acting ends retiring from the hollow cylinder.
In using the creaser the handle is brought into the position in which the creasing
tools are withdrawn; the charged cartridge case is placed upon the mandril and
held down firmly with one hand. With the other hand the handle is moved so as
to give motion through a small angle to the cap or cover, and thereby force the creasing
tools inwards. The said tools in their converging motion press upon and indent
the cartridge case with three equi-distant depressions or creases immediately in
front of the wad, and thereby fix the wad and charge in the cartridge case.
Instead of three, any other number of indentations or creases may be made
by the use of the requisite number of creasing tools and the appliances connected
therewith.
By the detached indentations or discontinuous crease produced by the use
of my Invention, the cartridge case is not weakened to the extent to which it is
weakened by a continuous crease, and can consequently be used a great number
of times.
The creaser may be converted into a recapper for capping and recapping cartridge
cases in the following manner :-A strong arm or bracket is fixed to the base of
the creaser, the said arm supporting a lever over the mandril. An ejector consisting
of a steel rod of small diameter is fixed axially on the mandril. The said ejector is
either pointed or concave at top, according as the spent cap to be removed is of
the ordinary kind, or has an anvil passing through the cap chamber. The lever
described carries an inverted cup in a line with the axis of the mandril, into which
cup the ejected cap is forced. The said cup is replaced by a short cylindrical
block when fresh caps are to be pressed into the cap chambers. The capping and
recapping apparatus is worked in a way essentially the same as that in which an
ordinary recapper is used.
