| 20110030542 | Projectile for a Stacked Projectile Weapon - Projectile stacking systems in which individual projectiles are clipped together to form a stack. The projectiles may be joined individually by a user before loading in a barrel, or during a loading process assisted by features on the breech of the barrel. The tail of each projectile includes a set of clips which engage the nose of a trailing projectile in the stack. Projectiles may be withdrawn from barrel and undipped as required by the user. | 02-10-2011 |
| 20110314996 | DRIVE AND QUICK STOP FOR A WEAPON WITH PREFERABLY A LINEAR BREECH OR AMMUNITION FEED - A drive, having a quick stop mechanism, for a breech is axially adjustable relative to a weapon barrel, and includes a motor, two counter-rotating chains and sprocket wheels that guide the chains. Engaging cams and control cams are integrated into the chains. A slide mounted at the bottom of the breech is displaceable transversely to the direction of fire and has a groove that the engaging cams engage to entrain the breech in a forward or reverse motion relative to the direction of fire. The engaging cam transporting the breech forwards is displaced from the groove while the control cam displaces the slide simultaneously to its center position via its ascent ramp, thereby allowing breech rest periods in the forward limit position. Firing causes the slide to move from the center position to the left hand side whereas it remains in the center position when no shot is fired. | 12-29-2011 |

| 20120132062 | BREECH DRIVE FOR A WEAPON - A drive for a weapon is provided, wherein rotational motion of a motor is converted to a forward or reverse motion of the breech in a simple manner using the Scotch yoke principle. In order to allow rest periods of the breech in the end positions, the crank radius is defined by a control cam, which changes when the crank is rotated. The hinge pin of the crank may be externally driven via a pinion shaft. A yoke pin is arranged in a groove of the crank so as to be radially displaceable and carries the breech carrier or the breech in a groove extending transversely to the direction of fire via a sliding block. Two rollers are arranged on the crank pin and run in control cams in the weapon or crank housing. The control cam is subdivided into different sectors/sections, thereby achieving the desired motion of the breech. | 05-31-2012 |
| 20120210859 | BREECH GUIDES FOR USE WITH BREECH ASSEMBLIES AND FIREARMS INCLUDING SUCH BREECH GUIDES - 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. | 08-23-2012 |
| 20130160636 | APPARATUS FOR OPENING AND CLOSING BREECH BLOCK AND CANNON HAVING THE SAME - An apparatus for opening and closing a breech block includes a cam follower, a housing, a first plunger, a rotation unit, a pressurizing unit, an open cam, a first elastic member, and a second plunger. In the present invention, in a state that the open cam is out of the range of a moving path of the cam follower so as to restrict rotation of the cam follower, the second plunger is inserted into the housing so as to support the pressurizing unit. This may allow a closed state of the breech block to be maintained after firing. Furthermore, in the present invention, a closed mode of the breech block may be converted into an open mode, through simple manipulations, e.g., by rotating the rotation unit, i.e., by moving the pressurizing unit. | 06-27-2013 |

| 20110290103 | DRIVE AND QUICK STOP FOR A WEAPON WITH PREFERABLY LINEAR BREECH OR AMMUNITION FEED - A drive for a breech/breech carrier renders it axially adjustable relative to a weapon barrel. The drive includes a motor, two engaging cams mounted on a chain arranged below the breech and guided around two sprocket wheels. A slide is mounted in a guide at the bottom of the breech/breech carrier so as to move at a right angle to the direction of fire, with a groove extending over its entire width. The respective engaging cam entrains the breech in forward motion relative to the direction of fire, or in reverse motion, once the shot is fired, and transports the breech forwards, is displaced from the groove, and moves backwards without the breech, thereby allowing breech rest periods in a forward position. During firing, the slide moves, whereas it remains stationary when no shot is fired so no further engaging cam can entrain the breech backwards. | 12-01-2011 |

| 20140251118 | BOLT ASSEMBLY WITH IMPROVED ROTATING LOCKING HEAD - A bolt assembly with improved rotating locking head, comprising a rotating locking head associated with a bolt body and movable with respect to the bolt body with a combined rotary and translational motion; the rotating locking head having at least two working positions: a closed position, wherein the rotating head closes the breech of the firearm, and an open position, wherein the rotating head is at a distance from the breech; the bolt assembly has an auxiliary pusher that biases the rotating head from the open position to the closed position. | 09-11-2014 |

| 20140102287 | FIREARM WITH ENHANCED RECOIL AND CONTROL CHARACTERISTICS - The invention comprises an improved recoil control device comprising a bolt head and an inertia block or slider for use in a variety of firearms. In one embodiment, the bolt head and inertia block are articulated so that the displacement of the bolt head results in a force component outside the firing axis of the barrel of the firearm. The device can be incorporated into firearms of a variety of sizes and configurations to produce recoil reduction and/or weight reduction advantages. | 04-17-2014 |

| 20080276796 | Weapon with breach mechanism - It is proposed that a loading chamber of a weapon with a breech mechanism no longer be part of a cannon tube but rather that it form, together with a breechblock, a unit, which additionally contains a device for firing ammunition and which can move relative to the bore portion of the cannon tube. This design solution can be used in all weapons with various and different breech mechanisms. | 11-13-2008 |
| 20130014634 | SEALING RING AND PROPELLANT CHARGE CARTRIDGE - A sealing ring obturates a propellant charge cartridge of an automatic firearm for caseless ammunition, in particular against an end face of a firearm element, in particular for a breech or a projectile cartridge. The sealing ring contains a sealing surface that can be brought into contact with the end face. The sealing surface contains a first region around an annular opening of the sealing ring and a second region around the first region. The second region is set back relative to a tangential surface to the first region. In addition, a propellant charge cartridge for an automatic firearm for caseless ammunition, has at least one of the sealing rings. The propellant charge cartridge preferably contains one or multiple, in particular two, propellant charge chambers, which are provided with a sealing ring on each of the breech side and the projectile cartridge side. | 01-17-2013 |
| 20150033934 | BLANK CHAMBER AND HOUSING - A blank handling device is provided for receiving and firing a blank cartridge for use in a non-gun. The handling device includes a housing having a blank receiving chamber sized and configured for holding the blank during firing. The blank receiving chamber includes a first axis and a first diameter. A gas discharging passageway capable of being coupled to a barrel of a non-gun, is provided that has a second axis and a second diameter. A gas flow passageway is fluidly coupled to and extends between the blank receiving chamber and the gas flow passageway for conducting gasses discharged by the firing of the blank cartridge between the blank receiving chamber and the gas discharging passageway. The gas flow passageway has a third axis and a third diameter. The third diameter is less than the first diameter for preventing the passage through the gas flow passageway of a projectile discharged in the blank receiving chamber. | 02-05-2015 |
