  • Patent number: 6079138
    Abstract: An automatic firing system with military applications, that uses the existing state of the art delayed blowback locking mechanism dating from the 1940's. The difference is that the mechanism is located above and in front of the bolt rather than behind the bolt. When firing the weapon, the pressure from the discharge will push directly back on the bolt. The delay rollers apply enough pressure against the bolt to cause a delay before the bolt will move. Once the bolt begins to move it will push the delay rollers up against the delay cam and compression spring. The size and stiffness of the spring combine with the mass of the bolt, cam and rollers to determine the speed which the bolt will travel. The bolt will move back, away from the barrel, pulling the empty cartridge with it. While the bolt continues to move, it will pull the empty cartridge case to the ejection slot in the side of the stock receiver. The empty cartridge case is then ejected by conventional means.

  • Patent number: 4856217
    Abstract: The present invention relates to smooth-bore guns having a tubular magazine and an operating system either semiautomatic indifferently of the inertial type, of the gas intake type or of the recoiling barrel type, or manual pump-operated or convertible from one system to the other, relating essentially to a new cartridge feed system adapted to these types of firearms.The invention comprises a new cartridge descent lever which, causes the cartridges to pass from the magazine tube into the barrel, either automatically or manually.For the feeding with semiautomatic operation of the firearm, part of the energy of the spring of the hammer of the firearm is used to cause the vertical rotation of the cartridge descent lever so that a cartridge exits from the magazine tube.For the feeding with manual pump operation of the firearm, the same movement is caused by the bolt when it opens manually, by means of the cocking rod, for the expulsion of the case in the barrel.

  • Patent number: 4723369
    Abstract: A bolt assembly for a firearm is constructed with three locking lugs, one of which is oriented down in unlocked condition as it is withdrawn past the magazine of the firearm. The body of the bolt is of reduced diameter with respect to the bolt head which carries the locking lugs. A cartridge depressor is mounted in association with the bolt body to effectively increase the diameter of the bolt body in the vicinity of the magazine to that of the bolt head.

  • Patent number: 4416076
    Abstract: A device for retaining cartridges in a tubular magazine of a semi-automatic shotgun when the cartridge in the firing chamber is being replaced, comprising a spring-loaded catch lever which is pivoted to the gun about a transverse axis, so as to be angularly displaceable between an inoperative position allowing the discharge of cartridges from the magazine, and an operative position blocking the discharge of cartridges from the magazine. The lever is displaced manually into its operative position and is held in this position by the action of the magazine spring until the gun is fired, whereupon the recoil causes the automatic release of the lever to its inoperative position.

  • Patent number: 4392319
    Abstract: A safety device for the trigger mechanism of a gas-operated-automatic/pump-action-manual shot-gun comprises an over-center thrust spring assembly pivotally connected at one end to a fixed point on the gun and at the other end to a stop member defining lever. The thrust spring assembly is pivotable between a first position, in which it biases the said lever into an operative position, bearing against the breechblock carrier, and a second position in which it stabilizes the said lever in an inoperative position, out of the path of movement of the breechblock carrier, preventing rebound of the stop member defining lever into the said path.

  • Patent number: 4276707
    Abstract: A cartridge/carrier locking device for an automatic gun including a latch plate pivotally mounted on an inner wall of a receiver to pivot in a seesaw like manner to have two ends thereof alternately protrude inside of the receiver. The front end protrudes to restrain a cartridge and the rear end to restrain a carrier. A spring pushes the rear end toward the inside of the receiver. Against this spring, a breechblock and a cartridge brought out of a magazine respectively restrict the protruding motion of the rear end until the breechblock moves backward approximately to a maximum extent. The position at which the breechblock comes to restrict the protruding motion of the rear end of the latch plate is arranged to differ from the position at which the cartridge comes to restrict in such a way as to allow the rear end to lock the carrier.

  • Patent number: 4164088
    Abstract: A cartridge/carrier locking device is used for an automatic gun loading arrangement of a type for removing a cartridge from a magazine onto a carrier by releasing it from a locked state for firing and for pushing it up into a barrel chamber by an upward sway of the carrier which takes place in response to the forward stroke of a breech block. A latch plate which is provided with a first claw part at its forward end for locking the cartridge and a second claw part at its rear end for locking the carrier, is pivotally attached to an inner wall of a receiver containing the automatic gun loading arrangement. The first and second claw parts serve, respectively, to lock the cartridge and the carrier as the claw parts alternately protrude into the inside of the receiver in a swaying fashion. A spring is arranged to push the second claw part of the latch plate to the inside of the receiver.

  • Patent number: 4141164
    Abstract: A magazine isolator is provided for a shutgun having a pump action of conventional type, including sliding linkage, operable sequentially from a battery position through an eject position and loading sequence back to the battery position. The magazine isolator has a selector adapted to the tubular magazine of the shotgun. The selector is movable between a single shot position and a repeat position. A stop surface is fixed to the sliding linkage of the pump action for contact with a shoulder associated with the selector. Upon positioning the selector in the single shot position, the shoulder is positioned for contact with the stop surface to inhibit the pump action from operating past the eject position. A spring loaded detent arrangement is adapted to selectively latch the selector in either the repeat or single position.

  • Patent number: 4024792
    Abstract: In an automatic shoulder arm designed as a gas operated weapon, especially an automatic rifle, the entire, fully operable weapon system, comprising the barrel, the bolt system, the gas operated action, the recoil spring arrangement, the cartridge feeding mechanism and a portion of the trigger mechanism, is slidably mounted in a receiver designed as a stock. During automatic fire, the weapon system is not returned to its initial position after every shot, but performs a recoil movement during a plurality of shots before it reaches a rear end position, which it maintains until the automatic fire is interrupted. The recoil movement can be utilized for controlling bursts of varying duration and cadence.

  • Patent number: 4014247
    Abstract: A gas-operated, magazine fed firearm includes a shell carrier for receiving shells from the magazine and lifting them into chambering position. An integral shell stop and carrier latch lever pivotally mounted in the receiver latches the shell carrier in its lowered, shell-receiving position and releases a single shell from the magazine to be moved onto the shell carrier by the magazine spring. The shell stop lever blocks the following shell from moving onto the shell carrier and releases the shell carrier for transferring the shell to chambering position. The shell stop lever shifts laterally to permit shells to be loaded past the carrier into the magazine from the feeding end.

  • Patent number: H211
    Abstract: This combined ejector-rammer, or ejectomer, is a single mechanical device ich performs the functions of both an ejector and a rammer for small arms which use cartridge type ammunition. An ejectomer lever is attached to the side of the weapon's bolt by means of a pair of pins and a spring. The pins move in elongated slots in the lever, one of which is linear and the other L-shaped. The forward end of the lever acts as a rammer to push each fresh round up a ramp into the firing chamber. After firing, a conventional extractor removes the spent cartridge case from the chamber and as the spent case moves down the ramp, the spring and the pins cause the lever to move in such a way that the extracted case is ejected.
