    Abstract: An improved single-shot rifle is shown having a rifle barrel secured to a receiver and having a lever-activated falling block action. The action includes a hammer and trigger each pivotally connected to the lever. A breechblock is moveable downwardly within a breechblock mortise provided on a rear surface of the receiver from a safety position wherein a firing pin carried thereby is aligned with a recess in the hammer and a firing position in which the firing pin is aligned with a striking surface of the hammer so that pulling the trigger releases the hammer and allows the striking surface thereof to strike the firing pin and fire the rifle.

  • Patent number: 5673505
    Abstract: A falling breechblock action for a single shot firearm, which is easy to make, assemble and disassemble, has an internal firing mechanism and a cooperating underlever. The action has a trigger, a hammer, an extractor and an extractor retainer, and avoids indirect linkages and cams and traditional complex safety mechanisms. The action links the underlever directly to the firing mechanism with a shaft. The underlever indirectly moves the breechblock. The initial downward movement of the underlever rotates the hammer rearwards into the cocked position and renders the complete mechanism safe. Further downward movement of the underlever draws down the breechblock. In so doing, the extractor is actuated by the breechblock. Upward movement of the underlever initially raises the breechblock and subsequently compresses a mainspring which is coaxial with the shaft. Only with the underlever fully up is the action capable of discharging a cartridge.

  • Patent number: 4787287
    Abstract: In an automatic weapon having a wedge-type breech 6, a linearly advancing and retracting feed finger 5 is provided to transport caseless ammunition 4 into the cartridge chamber 10a of the gun barrel 10, with the feed finger pushing against the rear face of the powder body 4a of the cartridged ammunition 4. An ammunition-receiving device is employed to prevent recoil of the ammunition 4 and consequent damage to the powder body 4a. The ammunition-receiving device includes leaf springs 2 which are disposed in the feed opening 3 of the gun housing 1, with the free ends 2a of the leaf springs 2 projecting radially inwardly to thus constrict the inner width of the feed opening 3. The free ends 2a of leaf springs 2 press on the outer surface of powder body 4a of the caseless ammunition and inhibit its forward movement.

  • Patent number: 4689912
    Abstract: A hand-held, single-shot grenade launcher including a receiver and attached stocks for both hands, a barrel slidable in the receiver, an assembly of Belleville springs for absorbing recoil and a breech connected to the end of the barrel. A grenade round is manually inserted in a firing chamber defined by the breech and the inner end of the barrel and cammed into firing position by a sliding breech block that carries a pivotal firing lever operated by a striker mounted in the receiver. The striker is biased by a helical striker spring and is cocked by a cocking lever associated with the right hand grip. The weapon is fired by depressing the cocking lever and thus pulling the trigger to cam the striker upward and release it from a sear operated by the cocking lever. Upon release the striker impacts an arm of the firing lever to drive a firing pin carried by the other arm of the firing lever into the primer of the grenade round casing.

    Abstract: An arrangement for bridging over the path traversed by cartridge being loaded via a loading tray and loading channel in a breech plate into the loading chamber of the weapon. The arrangement includes a trough-shaped flap which is pivotally mounted on the breech plate in such a way that it provides a guidance for the cartridge so that it cannot be damaged by a difference in height between the lower edge of the loading chamber and the breech block. The flap is pivoted about a horizontal axis when the breech block is in the open position and its free end remains at the level of the lower edge of the loading chamber until the cartridge casing has been securely guided into the loading chamber.

  • Patent number: 4452001
    Abstract: The present invention relates to improvements in firing and cocking mechanism of a breach loading firearm. This invention utilizes a substantially massive pin block disposed in a horizontal track between two counter biasing springs, the main spring and the counter spring. A firing pin extends from the chamber end of the pin block. When the cocked pin block is released, the main spring drives it toward the chamber and the momentum of the moving pin block carries the extended firing into contact with the primer of the cartridge despite the resistance of the counter spring. Lowering the breechblock allows a spring loaded ejector plate to spring backward and pull the spent cartridge casing from the chamber. In addition the ejector plate strikes a projection of the pin block and drives the pin block back to the cocked position. An extension of a lever which operates the action returns the ejector plate to the chamber so that the breechblock is able to rise unobstructed.

    Abstract: An electrically-fired gun, of the type having a breechblock slidable in a transverse passage across its breech, has a retractor mechanism mounted within the breechblock for retracting the firing pin electrode tip behind the face of the breechblock as it opens and closes. A retractor lever connected to the firing pin is controlled by positioning means comprising spring means biasing the lever in one direction, and a plunger cam cooperable with a wall of the transverse passage to displace the lever in an opposite direction. The positioning means serve to retract the firing pin when the breechblock is opened for reloading, and to extend it on reclosing.

  • Patent number: 4341031
    Abstract: An industrial gun, of the type having a transverse sliding breechblock, has a firing mechanism which automatically cocks and then releases a hammer as the breechblock closes. A sear is pivoted in the yoke or receiver of the gun in a position to engage and cock a hammer carried by the breechblock as the breechblock is moved from an open to a closed position. A cam surface on the sear bears against a cooperating cam surface on the hammer to release the hammer from the sear as the breechblock reaches the fully-closed position, in which a firing pin carried by the breechblock attains correct alignment with a shell in the gun chamber. A set screw provides an adjustable cam surface on the hammer to allow the correlation of the timing of the hammer release with the breechblock movement to be readjusted precisely as the parts wear with use.
