| 181 | Self-loading pistol in the form of a mechanically locked recoil loader | US440228 | 1982-10-28 | US4589326A | 1986-05-20 | Alexander Kuckens; Willi Korth |
| An automatic pistol is disclosed which is recoil-operated and has mechanical locking means. The locking action between the barrel casing and the breech member is effected by means of an amply dimensioned locking member pivotally supported within the breech member and participates in the movement thereof. Coupling means provided between the trigger lever and the striking lever are formed by crank-like means and are adapted to be controlled by corresponding control portions respectively provided on the trigger lever and the breech member or stock so that the striking lever will always move along the same distance whether the striking lever is manually cocked, cocked by the breech member, or cocked and released by pulling on the trigger. The disclosed pistol includes safety means and the pistol and safety means are operable easily and quickly with equal ease by both left-handers and right-handers. | ||||||
| 182 | Automatic gun | US955811 | 1978-10-30 | US4240324A | 1980-12-23 | William G. Smith; Ladd Yuhash |
| An automatic gun for firing a projectile by means of a separately loaded pellant case has a receiving frame in which an elongated barrel can reciprocate. The barrel, which has an axial bore from its breech to its muzzle, has a chamber member slidably mounted on its breech end. This chamber member, having a concavity shaped to hold the propellant case, is transversely displaced from alignment with the barrel to an unlocked position by an actuating means, in response to barrel recoil. | ||||||

| A firearm, particularly a short firearm for firing caseless ammunition, comprises a housing having a sleeve fixed therein with first and second spring members which are biased against a projection on the gun barrel in order to hold it against axial displacement in each direction. The barrel includes a breech portion with a magazine chamber, and cartridges are moved out of the magazine chamber into a cartridge chamber by a gas piston which is displaceable in a lock member which, together with the gas piston, seals the space in the cartridge chamber behind the cartridge during firing. The lock member includes projections which are engaged behind recesses of the rear breech portion of the barrel. The firing pin gas piston is moved rearwardly during firing, and it has a pin connection to a lock slider so that it and the lock member are rotated to move the projection on the lock member out of alignment with the projections of the breech portion of the barrel so that the lock member and the firing pin may be tracked against the force of a return spring. In a subsequent forward movement of the firing pin and the lock member, the next cartridge in the magazine is positioned in the cartridge chamber with the projectile portion located in the barrel for firing. | ||||||

| A toggle action piston in which an under-center toggle employing toggle links of two predetermined sizes providing a given hesitation is tripped to recede into its handle by the effects of gas pressure generated at the time of firing.
