摘要： 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 fired 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 firing pin, extractor 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 fits coaxially around the barrel. A coaxial helical spring fits between the barrel and muzzle sleeve to urge the muzzle sleeve (and bolt) to the forward firing 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 momentum of the escaping gases immediately following firing exerts a force against the sidewalls of the grooves to retard blowback of the slide assembly.

摘要： A handgun of the drop barrel type has an over-length firing pin coupled with a "pile-driving" barrel action that permits the firing of rifle load cartridges. A micro-precision timing sequence of the action causes the rearwardly propelled cartridge disposed in the floating drop barrel chamber to strike the fixed firing 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 captured 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 firing 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 cartridge and a specially configured firing pin is also disclosed 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 action but does not provide for the utilization of the gases from the discharged cartridge in recocking the firearm.
摘要翻译：落桶式手枪的手枪具有一个超长的打击销，与“打桩”枪管动作相结合，允许步枪装药筒的射击。动作的微精度定时顺序使得设置在浮动下落筒室中的向后推动的药筒在枪管仍然处于其向后移动的方向时撞击固定的击发销。在本发明的优选形式中，围绕接收管内部的筒的弹簧驱动致动器套筒向后推动桶，使得筒被点燃并且在将筒抵靠在后座板上的筒之前子弹从筒中排出与枪架一体。从筒体释放和膨胀的气体被筒和致动器套筒捕获并与由落下的桶形成的惯性配合，以将筒室锁定并密封抵靠后膛板。在使用离开机筒的子弹完成点火顺序之后，压力下降到接近零，而第二弹簧将筒向前拉动，致动器套筒已经通过膨胀气体返回到其起动状态。还公开了可以用于利用来自排出壳体的膨胀气体来均衡筒上的压力的结构，并且还公开了一种特别配置的击发销，以帮助弹出用过的料筒。手枪的第二种形式具有与正常触发器组件相反的手动启动的桶，并且本发明的第三种形式具有触发器操作的动作，但是不提供使用来自排出的盒的气体重新开启枪支。

摘要： An automatic machine pistol is provided, which is not subject to fouling, which is compact and light while incorporating a pneumatic recoil buffer, which resists muzzle climb, and which can be accessed and cleaned without disassembly. The machine pistol is comprised of a reciprocating bolt within a housing of the pistol. The reciprocating bolt is carried within the housing on four rails by eight roller bearings. No sliding contact is made between the bolt and any other portion of the pistol. A portion of the high pressure gas from the barrel is bled through a bleed hole in the barrel block or barrel into a gas port tube which is telescopically inserted into the bolt. The gas port tube delivers the portion of the discharge gas in a forward direction in opposition to the motion on recoil. An upwardly directed nozzle is communicated to the receiving bore within the bolt. The direction and force of the discharge gas within the gas port delivery tube and receiving bore within the bolt resist and buffers recoil, while the upwardly directed nozzle develops a downward thrust on the muzzle end of the pistol to avoid muzzle climb.

摘要： A firearm, in particular handgun, has a barrel mechanism with a barrel and a chamber, a closing mechanism with a slide and also a cylinder-piston mechanism for gas pressure-operated closure delay. The cylinder-piston mechanism has a hollow cylinder with a hollow cylinder wall. A channel is formed between the barrel mechanism and the cylinder-piston mechanism. The hollow cylinder wall is fitted with at least one reinforcing element. The firearm may be produced by the following process steps: introduction of a first portion of the bore into the basic body up to the recess; introduction of a second portion of the bore up to the hollow cylinder; drilling of the channel, wherein the drill is conducted through the bore; and introduction of the reinforcing element into the recess, wherein the bore is closed in a gas-tight manner.
