TRUVIDIONAL DEMOLIVATION.
Improved Apparatus for Uncapping, Reforming, and Recapping
Sporting Cartridge Cases.
1, JOHN EVANS, West Hill, Mansfield, Engineer, do hereby declare the nature of
this invention to be as follows:-
Each apparatus consists of a suitable shaped base plate provided with two or more
vertical pillars which support a perforated bed, from the top of the bed one or more
studs project to each of these one end of a hand lever is hinged, by which a stud is
pressed down over one of the perforations in the bed, below the bed under each
perforation a cylinder is secured to the base plate the lower portion of the cylinder is
slotted to receive the back end of a lever rocking on an axle pin carried by a stud
projecting from the base plate; sliding vertically in each cylinder is a plunger the
upper end of which lies within one of the perforations in the bed.
One plunger is recessed at its upper end, and is provided with a needle, the other
plunger is recessed at its upper end to receive the cartridge cap chamber, one per-
foration in the bed is slightly larger than the diameter of the cartridge case to be
reformed, the other perforation in the bed is smaller being of the same diameter as
the case when reformed, to uncap a case it is placed in the larger perforation and
forced down by the upper hand lever stud on to the needle in the plunger, the front
end of the rocking lever under it is then pressed down to throw up the plunger and
force out the case. The needle and plunger being at rest while the anvil of the cap
strikes the needle in its descent and is forced out of the case, at the same time the
capping end of the case is slightly reduced in diameter. It is then removed and being
inserted in the smaller perforation is pressed down by the upper hand lever to fully
reform the case, the lever is then raised to insert the cap, being again pressed down to
force the cap in place, the front end of the rocking lever under it is then pressed down
to force the case out.

I JOHN EVANS West Hill Mansfield, Engineer 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:
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a front view of the apparatus and
Figure 2 a plan of the same.
Each apparatus consists of a base plate A provided with four vertical pillars which
support a perforated bed B, from the top of which a stud projects and is hinged to one
end of a hand lever C, carrying a stud Chinged to one edge and a stud hinged
to the other edge, below the bed under each perforation a cylinder D is secured to the
base plate sliding vertically in one cylinder is a plunger E, the upper end of which
lies within one of the perforations in the bed and is recessed and provided with a
needle E in the other cylinder a plunger E' slides, having its upper end recessed to
receive the cartridge cap chamber. The perforation in the bed in which the plunger E,
slides is slightly larger than the original diameter of the cartridge case to be reformed,
and the perforation in which the plunger E slides is of the same diameter as the case
when reformed, the lower ends of the plungers rest upon the ends of a lever F,
rocking on an axle pin carried by a stud projecting from the bottom of the base
plate.
To uncap a cartridge case, the empty case is placed in the larger perforation over
the plunger E, and forced down by the stud C¹ of the hand lever C, on to the
needle E¹ on the plunger, the needle and plunger remain at rest while the anvil of the
cap strikes the needle in its descent and the cap is forced out of the case, the capping
end of the case being slightly reduced in diameter. The case is then removed and
being inserted in the smaller perforation is pressed down by the stud C2 of the hand
lever to fully reform the case, the lever is then raised to insert the cap, and again
pressed down to force the cap in place, the lever is then reversed and pressed down to
force the case out.
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 :-
:―
The construction and employment of improved apparatus for uncapping reforming
and recapping sporting cartridge cases.
