  • Patent number: 6457271
    Abstract: A magazine safety is provided for a semi-automatic firearm having a frame with a magazine well, a magazine, and a firing mechanism that includes a trigger bar. The magazine safety includes a latch and a latch bias. When the magazine is not received within the magazine well, the latch bias biases the latch into engagement with the trigger bar, thereby preventing the actuation of the firing mechanism via the trigger bar. Inserting the magazine completely into the magazine well causes the magazine to disengage the latch from the trigger bar, thereby preventing the latch from impeding movement of the trigger bar.

  • Patent number: 6405631
    Abstract: A semi-automatic handgun is disclosed including a frame having a barrel housing mounted thereon. A barrel is movably mounted on the barrel housing and has a cartridge chamber at its rearward end for receiving a cartridge therein. The barrel is movable between a rearward position and a forward position with respect to the barrel housing and is normally in its rearward position. The barrel moves forwardly in a straight line from its rearward position upon firing of the cartridge in the chamber to counteract the rearward energy of discharge, thereby reducing recoil. The handgun may be fired in either a single action or double action manner. The firing hammer of the handgun is re-cocked, upon firing of the cartridge, by means of a movable piston having a firing pin positioned therein with the firing pin engaging the hammer to move the hammer to its re-cocked position.

  • Patent number: 4531322
    Abstract: An apparatus for stunning animals and which has multiple propulsive charges. The apparatus is of the type in which a spike or plunger is projected toward the head of an animal to be slaughtered. The barrel of the apparatus is mounted on a part pivoted to the breech for pivotal movement about an axis parallel to the axis of the barrel. This arrangement mounts the barrel for pivotal movement between a position in which the barrel can be locked to the breech for firing, and a position in which the cartridge chamber of the barrel is aligned with cartridges in the cylinder of a magazine located in a handle connected to the breech. This arrangement permits simply pivoting the barrel into alignment with the magazine to load a cartridge into the chamber, and then pivoting the barrel back to the firing position in which it can be locked to the breech.

  • Patent number: 4019424
    Abstract: A cartridge soft feed mechanism for presenting the cartridge to the chamber f a gun in such a way that the axis of the cartridge experiences no lateral or angular movement during chambering. The cartridge is telescoped into the chamber without ramping, reducing the probability of damage to the cartridge and reducing the chance of chambering stoppage. The feed mechanism is inactivated by a chambered round sensor for refilling the magazine or removing and replacing a chambered round in order to permit barrel movement between its forward extended position and its rearward ready position. While the current weapon (30mm Multishot Grenade Launcher) utilizes a fixed breech and movable barrel, the mechanism is adaptable to movable breech fixed barrel weapons.
