Wedge-type breechblock for a gun

In a gun having a breech end, an arrangement comprising:

• a wedge-type breechblock disposed at the breech end of the gun;
• a cartridge chamber having a length L1 in a said wedge-type breechblock for accommodating propellant igniters;
• a propellant igniter magazine disposed adjacent said wedge-type breechblock and including a guide chute and individual ones of said propellant igniters lined up in a row in said guide chute, said individual propellant igniters each being partially encased by an exterior casing and having a length L2 which is longer than the length L1 of said cartridge chamber so that when one of said propellant igniter is loaded in said cartridge chamber in a firing position, a rear portion of said propellant igniter remains within said casing, and each said casing has an annular groove;
• loading means for loading one of said propellant igniters into said cartridge chamber from said magazine, said loading means including an engaging lever having a front, spring tensioned portion which is pivotably fastened to said breechblock and which engages in said groove of a respective said casing in order to load or extract the respective said propellant igniter into and out of said cartridge chamber;
• and
• a firing mechanism operatively disposed at said wedge-type breechblock for detonating a respective one of said propellant igniters in said cartridge chamber.

• a propellant igniter magazine disposed adjacent said wedge-type breechblock and including a guide chute and individual ones of said propellant igniters lined up in a row in said guide chute, said individual propellant igniters each being at least partially encased by an exterior casing and having a length L2 which is longer than the length L1 of said cartridge chamber so that when a propellant igniter is loaded in said cartridge chamber in a firing position, a rear portion of said propellant igniter remains within said casing, and wherein chain studs are provided and connect said casings with one another, and said casings each having a length which is approximately the same length as that of said propellant igniters, having a slot-shaped opening parallel to a longitudinal axis of said casing, and includes, on their side facing the wedge-type breechblock, means for centering the propellant igniter disposed in the respective said casing;
• loading means for loading one of said propellant igniters into said cartridge chamber from said magazine;
• and
• a firing mechanism operatively disposed at said wedge-type breechblock for detonating one of said propellant igniters in said cartridge chamber.
