  • Patent number: 9863728
    Abstract: A cylinder breech block device (100) of a repeating firearm has a breech block cylinder (200) pivoted in a system housing (160) of the repeating firearm for execution of repetitive action thereof and capable of being locked to said system housing (160) for firing a round. A firing pin (140) capable of being cocked by a tension spring is mounted for linear displacement in the direction of a cartridge (141) stored in a magazine (141) of a barrel (143). Cocking of the firing pin (140) is effected by causing rotation, through a predefined angle, of a breech bolt handle (300) rigidly connected to a tension crown ring (400) that is pivoted on a central shaft (210) of the breech block cylinder (200).

  • Patent number: 8997623
    Abstract: A locking block device (100) provided in the region of a cartridge chamber (121) of a handgun barrel (120) has a locking block (110) for releasably locking the barrel (120) to a breech prior to firing, and has a control member (111) having a control guide (112) for swinging out the barrel (120), after firing, for the purpose of separating the barrel (120) from the breech, and further has a feed ramp (140) formed in the region of a stop member (130) of the locking block (110) for feeding a cartridge, stored in a magazine of the handgun, into the cartridge chamber (121) following ejection of a fired cartridge. A modular design capable of being adapted to meet specific requirements is achieved in that the feed ramp (140) is formed on a ramp member (150) capable of being separated from the locking block (110) and releasably locked to the locking block (110).
