  • Patent number: 9021731
    Abstract: A double-magazine (“Dmag”) able to house projectile ammunition for a projectile launcher having a first ammunition channel, a second ammunition channel, and a flexible projectile control bar (“FPCB”) is disclosed. In one embodiment, the first ammunition channel contains a first set or column of projectiles and the second ammunition channel which is situated in parallel to the first ammunition channel is configured to house a second set of projectiles. Dmag also includes a follower with a follower lock capable of moving along the first ammunition channel. The follower is configured to push the first set of projectiles toward a first ammunition supply port of the first ammunition channel. The FPCB has a first flexible flap which keeps the first set of projectiles from reaching the loading port of the launcher until the follower lock is released.

  • Patent number: 9010006
    Abstract: A method and apparatus for intentionally slowing the speed at which detachable ammunition magazines can be interchanged in a firearm receiver. A magazine catch assembly includes a latch adapted to engage a recess of a standard magazine in the magazine well. A hand-activated crank interacts with threads of a push-rod portion of the latch so that manual rotation of the hand crank in one direction (e.g., counter-clockwise) displaces the latch after a sufficient number of turns. Reverse rotation of the hand crank returns the latch to its engaged condition ready to automatically re-engage the next magazine inserted into the firearm receiver. Alternatively, viscoelastic foam or other mechanical time-delay feature can be used instead of screw threads to introduce a mechanically transmitted dwell period before the latch is actuated.

  • Patent number: 8683725
    Abstract: A magazine-latching assembly for a firearm is described. The magazine-latching assembly includes a latch body that is slideably disposed in a receiver. The latch body includes a notch that accepts an aft tab on a magazine. A locking member is pivotally disposed in the latch body and engages the receiver to lock the latch body in a forward position in which the magazine is locked into the receiver. The assembly includes a magazine-release lever that forms a portion of a trigger guard. Actuation of the magazine-release lever pivots the locking member out of engagement with the receiver, moves the latch body out of engagement with the aft tab of the magazine, and draws the forward tab of the magazine out of engagement with the receiver. The magazine-latching assembly is useable with twin-tab magazines and with bullpup-style firearms. The magazine-release lever is also configured for ambidextrous operation of the firearm.

    Abstract: A method of loading individual caseless cartridges sequentially into a firearm firing chamber by the expansive force of a small detonation in the magazine focused locally on the current top cartridge in a magazine without damaging remaining cartridges. Small individual propelling charges containing an igniter microchip located in the magazine behind each cartridge provides the loading thrust. More energetic charges containing igniter microchips are imbedded in the cartridges to fire the cartridge in the firing chamber at will.

  • Patent number: 7669512
    Abstract: An automatic clutch is integrated in a weapon system between an ammunition feed system and a cannon. A feeder feeds ammunition into the cannon. The clutch mechanism includes an actuator, a locking pin with an assisting spring or the like, and locking cams. The clutch mechanism allows the drum shaft of the cannon to be disengaged from the gear of the feeder between the cannon and the ammunition supply system and thus from the conveyance mechanism of the feeder.

  • Publication number: 20090120271
    Abstract: In order avoid ammunition feed from within a protective cell of a turret (1) or an ammunition magazine, a type of ammunition supply system (6) is disposed around the entire or partial circumference of the turret (1). The ammunition supply system (6) has at least one ammunition channel (10, 11) filled with ammunition (5), whereby a drive (13) is incorporated for the transport of the ammunition (5), if the weapon (3) is not designed to pull the ammunition (5) by itself. In this case, an endless chain (12) works together with the drive (13), wherein the endless chain is movable in two axes. This endless chain enables transport of the ammunition (5) around the radii (R) of the turret (1).

  • Patent number: 7509767
    Abstract: An improved base pad for a firearm magazine that more securely attaches to the bottom of a magazine tube in a manner which is easier and faster to attach or remove therefrom when cleaning the magazine. The improved base pad has a body member with a pair of ends and a pair of sides. The sides each have a groove configured to slidably receive, preferably snugly, the lips at the bottom of a standard magazine tube. One end of the base pad has an outwardly extending section with an upwardly facing, generally planar face. A securing mechanism at the outwardly extending section has an upwardly disposed projection that selectively engages one wall of the magazine tube to secure the base pad thereto when in its engaged position and allows removal of the base pad when in a disengaged position. In a preferred embodiment, the securing mechanism is a detent device.
