  • Patent number: 8459165
    Abstract: Breech guides for use with breech assemblies and firearms including such breech guides are disclosed. An example breech guide for use with a breech assembly of a firearm includes a support element positioned within the breech assembly and a control element on the support element, the control element is adapted to control a cartridge-feeder mechanism of the firearm. The example breech guide includes a guide element on the support element. The guide element is adapted to guide the breech assembly relative to guide rails of the firearm. The support element extends along an axis of symmetry substantially perpendicular to a bore axis. The control element and the guide element being substantially coaxially positioned relative to the axis of symmetry.

  • Patent number: 8065950
    Abstract: An automatic pistol essentially consists of an immovable barrel, a breech with a firing pin and a cartridge extractor, a breech frame, a spring-loaded device for the removal of gas with a gas piston and a gas cylinder, a firing mechanism and a magazine. The barrel is fitted with an end piece, which is located in the lower part of the rear end of the barrel. The design of the breech allows for the displacement of its front part downwards, when the breech is in its front end position. The front part of the breech is fitted with side locking lugs. The corresponding locking grooves are located in the cavities on the end piece of the barrel. The gas piston has an opening for ejecting the cartridge casing. In the course of the backward movement, the gas piston unlocks the breech and draws it back. In the forward movement, the breech is carried forward and pushed downwards. The gas cylinder is located at the front part of the barrel and encompasses the barrel. Along the length of the barrel gas ducts are fixed.

  • Patent number: 5463828
    Abstract: A gun 10, such as a shot gun or the like, of the type which includes a firing pin carrying bolt 25 which is reciprocally movable relative to the firing chamber 23 of the gun 10 between a first or firing position where the firing pin 29 can engage the rear end of a cartridge 22 located in the firing chamber 23 of the gun 10, to a second or reload position located towards the rear end of the gun 10, the gun 10 being characterised in that it includes at least two locks for positively maintaining the bolt the firing position while and after a shot has been fired and before the gun is reloaded, the locks comprising a first one 39 located rearwardly of and at a level above the firing chamber 23 of the gun 10, and at least one of two further locks, the second one 51 located at a level below and in a position forward of the firing chamber 23, and a third one 77 located at a level below and in a position rearwardly of the firing chamber 23.

  • Patent number: 5227578
    Abstract: This weapon has an axially moveable bolt which is removed from the path of an incoming cartridge so that the cartridge can be moved from its feed position directly along the axis of the bore into the gun chamber. After the bolt "disappears" from the path of the incoming ammunition, it then reappears behind the cartridge to move it along the barrel axis.

  • Patent number: 5085123
    Abstract: A device used especially in a large caliber weapon for controlling the train of motion of an ammunition unit during the ramming thereof in the weapon, and of the case of the ammunition unit on firing of the gun includes an impact arrangement which upon ramming of the ammunition unit enter into interaction with and retard the ammunition unit. An energy storing device is chargeable through the impact with kinetic energy existing in the retarding ammunition unit. In response to energy transmitted from the energy storing device the closing of the breech block is activated. The breech block in the closed position retains the case of the ammunition unit during the firing and during a predetermined portion of the rearwardly directed movement in the gun effected on firing. The impact arrangement includes an impact member interactable with a flange on the case and displaceable in the longitudinal direction of the gun, and an impact spring means interactable with the impact member and with an impact piston.

  • Patent number: 4494440
    Abstract: A weapons system for single-barrel automatic cannons uses PRUNIT rounds consisting of a projectile and a casingless solid body of propellant affixed to the projectile. A respective arming set is provided for at least some of said weapons to form central units therewith. Each arming set comprises means defining first and second energy-flow paths with respective shafts adapted to transmit torque from input ends to output ends of the path. Both of the shafts are connected to a wedge-type breech block for shifting same between open and closed positions. One of the shafts is connected to a loader and the other to a belt feeder for the PRUNITs.

  • Patent number: 4278008
    Abstract: A cartridge containing a propellant charge, and a separate projectile are dividually loaded into two independently operable sections of a gun breech assembly. The automatic loading operation is facilitated by separating the two sections during recoil movement, loading each component, and re-aligning both sections with the gun barrel in the battery position at the conclusion of counter-recoil movement.
