  • Patent number: 9518791
    Abstract: In a breech loading firearm, an extractor arm is slidingly arranged within a cavity beneath the barrel. The extractor arm has a retracted position and an extended position. In the retracted position, the extractor arm is constrained from rotating, and in the extended position, the extractor arm has at least one degree of rotational freedom in the cavity without bending. The intermediate portion of the extractor arm is thicker than the distal end such that the second thickness fits within the cavity when the extractor arm is in its retracted position. The reduced thickness at the distal end provides a space between the extractor arm and a wall of the cavity when the extractor arm is in its extended position to provide for the rotation of the extractor arm within the cavity in its extended position. The proximal end of the extractor arm has an angled face.

  • Patent number: 8677904
    Abstract: A tricolor signal flare projectile configured for use with a “high-low” projectile launching system such as the U.S. Army's M-433. The projectile includes a body having a cylindrical side wall and an aft closure. The body's forward portion is open, which provides access to a hollow interior. A delay assembly is installed in the aft closure. The delay assembly includes a delay column. A signal igniter is located just forward of the delay column in the hollow interior of the body. The hollow interior also includes separate volumes of red, white, and blue illuminant. An ogive closes over the top of the hollow interior of the body, thereby encapsulating the other components. When the projectile is fired from a launcher the propellant gases burning with the launcher ignite the delay column. The delay column burns while the projectile travels along its trajectory. After the passage of a desired time interval, the delay column ignites the signal igniter.

    Abstract: A modified projectile round which is configured to function with a propellant cartridge such as described in U.S. Pat. No. 7,004,074. The projectile assembly uses a High-Low gas pressure cartridge to launch the projectile. When the high pressure cartridge is ignited, hot propellant gases rupture a burst cup and shoot propellant gases toward the aft end of the projectile. The hot propellant gases impinge against a delay carrier located in the aft end of the projectile. The contents of the delay carrier are thereby ignited. The delay carrier includes one or more delay columns ultimately terminating in an igniter charge. The delay columns burn as the projectile is in flight. A specified amount of time later, the igniter charge ignites an ignitable payload—such as a marker flare candle.

The device consists of multiple round flare holders or tubes, which are snapped around a central core holder. The core holder will accommodate four (4) to six (6) flares dependent upon the model. Each flare tube has a waterproof cap. To use, a person would select one or more flare tubes from the central core, remove each cap, and slide out the flare. A locking system to prevent the flare from falling all of the way back into the tube is then activated, along with a spring-levered two-foot support stand. The stand is then deployed with the flare ignited and dropped into the tube. When finished, the spent flare can be discarded, a new one placed in the holder, the cap replaced, and the holder snapped back into the central core holder, thus making the device ready for the next use.

  • Patent number: 6666351
    Abstract: A dispenser structure for chaff countermeasures includes at least one chaff dispenser having a dispenser tube with a tube sidewall, a dispensing opening, and a female thread structure in an inner surface of the tube sidewall, and a male worm gear engaged to the female thread structure of the dispenser tube. A drive structure has a motor mount upon which the worm gear is rotatably supported, with the motor mount being mechanically reacted to prevent the motor mount from turning, and a drive motor affixed to the motor mount and having a motor output connected to the worm gear to controllably turn the worm gear. Chaff countermeasures are disposed within the dispenser tube between the worm gear and the dispensing opening, so that they may be pushed out the dispensing opening as the motor turns the worm gear.

  • Patent number: 6659012
    Abstract: An ejection device for ejecting a plurality of submunitions (24a-d) having an adapter (10) including a control unit (12, 13, 14a-c, 15a-b, 16) and adapted for releasable fastening in an ejection barrel (2) of a discharger (1), and a submunitions cluster (20) including the submunitions and adapted for releasable connection, both mechanical and electrical, with the adapter. In the assembled condition of the device, the submunitions cluster is connected with the adapter, permitting submunitions to be ejected from the submunitions cluster. The control unit of the adapter controls the device to eject submunitions in one or more of a variety of ejection modes, such as sequentially one by one or at least in part simultaneously. The period between ejection of two consecutive submunitions may be adjustable. The ejection device may be integrated into a discharging unit including at least one discharger (1), such as a conventional discharging unit.

  • Patent number: 6393990
    Abstract: This invention relates to a firing launching system and method which comprises a base having a plurality of apertures. The plurality of apertures receive a plurality of mortars which, in turn, receive a plurality of Pyrotechnic projectiles which may be situated in the plurality of mortars, respectively. The Pyrotechnic projectiles may then be ignited and launched to provide a fireworks display. The base may be a one-piece molded solid construction and provided with the plurality of apertures such that at least two-thirds of each of the plurality of mortars is encased to provide support to a wall of the mortar. The base may be provided with a plurality of apertures having a common diameter for receiving a common size mortar or receiving one of a plurality of sleeves, each having the same outer diameter, but a varying inner diameter to permit the sleeve to receive a different sized mortars.

  • Patent number: 6286429
    Abstract: A longitudinal launcher tube made substantially of polyurethane resin or plastic having a rear end closed by a transverse rear wall and an open front end. The invention allows a projectile to be housed in the tube and adapted to slide longitudinally inside it towards the front, to be expelled from it via the front end tube, means for defining with the tube and projectile a rear gas expansion chamber immediately to the rear of the projectile, and an impulse cartridge adapted on command to develop gas pressure in the rear chamber to cause the expulsion of the projectile via the front end of the tube. The apparatus is a pyrotechnic device for rigidly supporting fireworks such as mortar-type, rocket-type, projectile-type, and other pyrotechnic devices so that the launcher device is reusable, whereby the launcher substantially retains its integrity after each launch to minimize harm caused to persons and the environment.
