FOR

page_text: EXTRACTING CAPS FROM THE BASE OF BREECH-LOADING CARTRIDGE CASES," to
be as follows:-
:-
Heretofore difficulty has existed in extracting caps from Berdan and
other cartridge shells or cases for breech-loading fire-arms in which the
cap is inserted into a recess in the base, and in which the orifices for
transmitting the flash from the cap to the charge are made at the side
or sides of the anvil on to which the cap is struck to ignite it.
By this Invention we arrange apparatus for removing the cap by
forcing a cutter or tooth through the top of the cap, the cartridge case
then being turned so as to incline it to the tooth or cutter, thereby
raising the cap out from the recess. For this purpose we drop the
cartridge case into a ring, so that the flange at the base of the cartridge
may rest upon it. The ring has pins or axes standing out from it at two
opposite sides, upon which it can be turned, and has also a lever handle
fixed to it, by which it can be held in any desired position. When the
cartridge case is thus held in the ring a cutter or tooth carried by a lever
handle having a slot at opposite end is brought down on to and forced
through the top of the cap. The ring carrying the cartridge case is then
turned on its axes, so that the base of the cartridge in place of being
nearly at right angles to the cutter or tooth is inclined to it, and the
the
cap being held by the tooth is thereby drawn out from its recess,
lever sliding slightly to the left. The lever carrying the tooth is then
turned back to be out of the way, and by turning over the ring the
cartridge case may be allowed to drop from it. The lever carrying
the tooth or cutter is jointed to a short standard which projects up
from the back end of a plate or bed. At the front of the bed a slot
or recess is formed in which is received the ring above mentioned. The
axes of the ring drop into grooves in the upper surface of the bed, and
are held there by small plates jointed to the top of the bed, being turned
round so as to come above them. The under side of the bed may carry
a screw clamp, by which it can be fixed to the edge of a table or bench.
