[57] ABSTRACT A handgun of the drop barrel type has an over-length ?ring pin coupled with a “pile-driving” barrel action that permits the ?ring of ri?e load cartridges. A micro

precision timing sequence of the action causes the rearwardly propelled cartridge disposed in the ?oating drop barrel chamber to strike the ?xed ?ring pin while the barrel is still in its rearwardly moving direction. In the preferred form of the invention a spring driven actuator sleeve surrounding the barrel interiorly of a receiver tube propels the barrel rearwardly such that the cartridge is ignited and the bullet discharges from the barrel prior to the seating of the barrel against a breech plate that is integral with the gun frame. Gases escaping and expanding from the cartridge are cap tured by the barrel and actuator sleeve and cooperate with the inertia created by the falling barrel to lock and seal the barrel chamber against the breech plate. After the ?ring sequence is completed with the bullet leaving .the barrel the pressure drops to near zero and a second spring pulls the barrel forward, the actuator sleeve having already been returned to its cocked condition by the expanding gases. Structure is also disclosed which may be used to utilize expanding gases from a discharging shell in equalizing the pressure on the car tridge and a specially con?gured ?ring pin is also dis closed to aid in the ejection of a spent cartridge. A second form of the handgun has a barrel that is hand actuated as opposed to a normal trigger assembly and a third form of the invention has a trigger operated ac tion but does not provide for the utilization of the gases from the discharged cartridge in recocking the ?rearm.

[57] ABSTRACT

A pistol has a trigger 18 pivotal between a forward rest and a rearward depressed condition. It has a ?ring pin assembly 60 incorporating a ?ring pin 68 and a trans verse nose 74. The assembly 60 is translational parallel to a barrel. When in rearward, cocked condition as illustrated. a ?ring pin 76 is compressed to propel it forward when released. A transmission member 50 is pivoted at a fore end to the trigger 18 and is guided for displacement along a cocking path. The nose 74 extends into the cocking path. Depression of the trigger dis places the member 50 along the cocking path. The member 50 abuts the nose 74 and cocks the assembly 60. The invention provides a pivot member 64 which hooks onto the member 50 and de?ects it out of its cocking path to release the nose when the assembly 60 is cocked. A resetting formation 96 is provided on a movable slide 14 to reverse pivot the pivot member 64 to disengage it from the member 50 when a cartridge has been ?red.

Dabei sind dieVerschlussvorrichtung (17) und der Vorderschaft (12)derart gekoppelt, dass beim Verschieben des Vorder-

schafts (12) die Verschlussvorrichtung (17) entgegenge-setzt zur Verschiebungsrichtung des Vorderschafts (12)betätigbar ist. Hierdurch wird erreicht, dass der Vorder-schaftrepetierer (10) ohne Arretierungsvorrichtung si-cher zu handhaben ist und im schussbereiten Ausgangs-zustand keine Repetierhublücke aufweist. Weiterhin wirdeine auf die Ergonomie des Schützen abgestimmte Waf-fe geschaffen, die in geschlossenem bzw. schussberei-tem Zustand ein gefälliges Erscheinungsbild aufweist.

[57] ABSTRACT A machine pistol with means for retarding blowback of the slide assembly. The device has both right hand and left hand stocks to enable the weapon to be ?red from a comfortable visual sighting position at eye level with the wrist axes perpendicular to one another. The slide assembly includes a bolt that carries the ?ring pin, ex tractor and ejector and that reciprocates relative to the receiver and barrel, and a tubular cylindrical muzzle sleeve removably connected to the forward end of the bolt and that ?ts coaxially around the barrel. A coaxial helical spring ?ts between the barrel and muzzle sleeve to urge the muzzle sleeve (and bolt) to the forward ?ring position wherein the forward end of the muzzle sleeve extends outwardly beyond the end of the barrel. A plurality of an annular internal grooves are formed in the forward end of the muzzle sleeve so that the mo mentum of the escaping gases immediately following ?ring exerts a force against the sidewalls of the grooves to retard blowback of the slide assembly.

[57] ABSTRACT A ri?e which is comprised of a barrel, an internal striker, a ?ring device connected to the striker, and a base which includes the butt and the lower part of the weapon. The striker receives a spring in a hole, which rests in a rear plug of the barrel. The ?ring mechanism is connected to a bolt lever and safety which inserts transversely therein. The ?ring mechanism is at the same time a safety, since when the weapon is loaded it is in non-?ring position, and the outside activation of the safety catch is necessary to make the discharge.

[54] FALLING BREECHBLOCK ACTION FOR A [57] ABSTRACT SINGLE SHOT FIREARM _

A falling breechblock action for a single shot ?rearm. which [76] Invgntor: Mark Phillips. RO_ BOX 163_ Caledon is easy to make. assemble and disassemble. has an internal

East_ Ontario‘ Canada_ LON 1E0 ?ring 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 tradi

[21] App 1' No‘: 762594 tional complex safety mechanisms. The action links the [22] Filed: Dee 9, 1996 underlever directly to the ?ring mechanism with a shaft. The

underlever indirectly moves the breechblock. The initial [51] Int. Cl.6 .............................. .. F41A 15/10; F41C 7/06 downward movement of the underlever rotates the hammer [52] US.

(57) ABSTRACT

Automatic and semi-automatic ?rearms of remarkably reduced mass yet capable of long-range accuracy because of unique recoil reduction are characterized by (A) a temporary combination of a barrel, an integral breech and a separable chamber that in operation of the ?rearm is moved by a compressed spring distally before and While a chambered cartridge is ?red, (B) run-out of such temporary operative combination diminishes ?rearm recoil, (C) recoil of the temporary operative combination recompresses the spring and (D) the separable chamber is loaded With a round While spatially separated from the breech and barrel.
