  • Patent number: 5452534
    Abstract: A semi-automatic weapon having a magazine well in the receiver section thereof. The well has opposed side walls and end walls to describe a box like enclosure for receiving a cartridge magazine. A bottom wall is also provided which guides the magazine vertically into the well. An opening is formed in one of the side walls that has a geometry that limits the size and shape and thus the capacity of a magazine that can be inserted through the opening into the well.

  • Patent number: 5435088
    Abstract: The firearm comprises a manual control (13) for deactivation of the retainer of a cartridge magazine (8) by release of a tooth (16) from a notch (17) of the magazine and a device for the automatic ejection of the magazine. The automatic ejection device comprises a finger (25) for the actuation of the tooth (16), which is integral with the cartridge elevator piston (19) of the cartridge magazine (8), to come against the retainer of the latter and cause its ejection before the end of the elevation stroke of the cartridge elevator piston during the chambering of the last cartridge (12) under the thrust of the spring (20) of this piston against an activation spring (18) of the retainer. After the ejection of the empty cartridge, the retainer (13) is again activated by its spring (18) and, during the replacement of this magazine, a cartridge (12) is thus chambered and the firearm is ready to fire.

  • Patent number: 5072537
    Abstract: A magazine catch assembly for a firearm includes a pair of opposing magazine catches supported for pivotal movement toward and away from each other between magazine retaining and releasing positions. In the magazine retaining position the magazine catches cooperate with a part of a magazine to releasably secure the magazine within a magazine well. A manually operable actuating member disposed between the catches and biased toward a first position corresponding to the magazine retaining position of the catches is moveable to a latching position corresponding to the releasing position of the catches in response to movement to its second position whereby the magazine is free to drop from the magazine well. Movement of a magazine out of the magazine well resets the magazine catches in magazine retaining position.

  • Patent number: 5056252
    Abstract: A pump action shotgun loaded from a magazine tube has a box magazine which feeds successive rounds of ammunition into the magazine tube through an opening in the side of the tube. Each successive round of ammunition is fed from the magazine tube into the receiver of the gun by a plunger connected by a rack and pinion mechanism to an action bar which moves the breech bolt between its retired and battery positions. The rack and pinion mechanism maintains the plunger out of the path of a round of ammunition fed into the magazine tube from the box magazine when the breech bolt is in its battery position and moves the plunger through a distance greater than the distance between the retired and battery positions to move a round of ammunition from the magazine tube into the receiver when the breech bolt moves from its battery to its retired position. The box magazine is adjustable to accommodate shells of differing lengths.

  • Patent number: 4867039
    Abstract: A semiautomatic gun which can be used to fire two types of ammunition comprises first and second bolts and a selector assembly operated by a user of the gun. The selector assembly selectively permits loading and firing of one type of ammunition. The gun has only a single trigger for firing either of the bolts selected by the selector assembly and the gun may be a combination of a shotgun and rifle or any other desired configuration. Each of the bolts are movable in a forward and rearward direction when fired and have bolt lock-up bearings for preventing such movement at other times. A reciprocable forestock is provided with a forestock lock release. The forestock can be pumped by the operator to initially load a round of ammunition into the chamber selected by the selector assembly.

  • Patent number: 4484404
    Abstract: A protective carrier for holding a loaded spare magazine in a position of readiness for immediate insertion into operative engagement with a firearm. A latch release mechanism is operable simultaneously with the operation of the magazine release mechanism of the firearm, permitting an empty magazine and a loaded spare magazine to be released together, the empty magazine being allowed to fall clear of the firearm while the loaded spare magazine is grasped and inserted into the weapon for use in a minimum amount of time. The spare magazine carrier of the invention protectively surrounds the open upper end of the spare magazine to shield cartridges held therein against contamination by dirt, mud, and the elements, in order to help avoid malfunction or damage of the weapon.

  • Patent number: 4471549
    Abstract: A self-loading firearm for firing rubber bullets and the like has an actuating mechanism comprising a toggle linkage which is straightened on operation of the trigger against its spring bias. Initial straightening of the toggle linkage moves the breech block forward to locate a round of ammunition in a short socket at the chamber end of the barrel. As the toggle linkage moves over center it locks the breech block forward and displaces a sear to release the firing pin. The round is fired with its case virtually unsupported. On release of the trigger the toggle mechanism is bent so withdrawing the breech block and the spent round which is automatically ejected. The firing pin is simultaneously re-cocked. Rotary and vertical stacking rechargeable magazines are described, from which a fresh round is automatically fed to the breech on ejection of a spent round.

  • Patent number: 4450641
    Abstract: A magazine floor plate latch for releasing the hinged floor plate of a cartridge magazine in a bolt action firearm. A spring biased latch having two upper legs and one lower leg is positioned in a central aperture in the front face of a trigger guard. The latch is adapted to pivot about a pivot point at a line of contact between a pointed surface in the trigger guard extending upward and fitting into a notch formed in the lower leg of the latch. The latch is normally biased by a spring so that one of its upper legs blocks the floor plate to keep it from swinging open about its hinged end. The floor plate is released by applying pressure on the latch so that it pivots until this upper leg no longer blocks the plate. This upper leg has a curved locking surface with a center of curvature offset from the pivot point to enable the locking surface to relatch the floor plate tightly against the bottom of the magazine as the latch pivots to its normally spring biased position.

  • Patent number: 4286499
    Abstract: Cross axis shell feeding apparatus for firearms comprises symmetrical shell pivoting or turnaround means having an internal pivoting chamber configured for receiving, and pivoting through 90.degree., shells from an associated linear shell magazine in which the shells are loaded in either cross axis direction. The shell pivoting chamber, formed having shell engaging, or camming surfaces which cam the shells through 90.degree. of rotation, is shown configured for pivoting tapered casing, rifle-type shells. Shells are pushed forwardly through the shell pivoting means by first and second stage rammers mounted to reciprocate with the firearm bolt assembly. To prevent jamming of shells being pivoted 90.degree. in the shell pivoting means, shell engaging portions of the first stage rammer swing aside after a shell has been pivoted from an initial cross axis orientation through approximately 75.degree..
