摘要:
The firearm (10) fire projectiles (22 22A) by ignition of a separate propellant cartridge (24) disposed therebehind. The firearm comprises a body including a receiver (12), a barrel (14) connected to the receiver, and a firing chamber (17) communicating with a bore of the barrel. A bolt (20) is slidably mounted in the body and includes two pockets (26,28) for receiving the projectile (22) and the cartridge (24) and for advancing them to an armed position within the firing chamber (17). In order to increase the safety of the firearm in use and of the manufacture and storage of the cartridge the primer charge (66) for igniting the cartridge (24) is disposed within a metal casing (48) within the projectile (22 22A). A portion (32) of the bolt (20) is arranged to ignite the primer charge (66) when the projectile reaches the armed position.
摘要:
A semi-automatic pistol of the type which has a bolt (19) which is driven aft by gases as a result of a fired bullet. It drives aft and ahead of a striker assembly (12). The latter includes a plate (15) and a striker element (16) with a striker pin (16t) supported on the plate (15) toward the bolt (19). A hollow cylindrical sleeve (32) with a closed bottom (32f) extends from a hole in the plate (15) in the bolt direction. A substantially stationary aft plate (30) supports a post (20) on which one end of a striker assembly return spring (22) is supported. The striker assembly return spring (22) extends over the post (20) and into the sleeve (32) through said hole, whereby when said bolt (19) moves aft the sleeve (32) enters the bolt (19), enabling the bolt (19) to move aft in the body.

A self-loading firearm for firing rubber bullets and the like has an actuating mechanism comprising a toggle linkage (13, 17) which is straightened on operation of the trigger (6) against its spring bias. Initial straightening of the toggle linkage (13, 17) moves the breech block (15) forward to locate a round of ammunition in a short socket (83) at the chamber end of the barrel (1). As the toggle linkage (13, 17) moves over centre it locks the breech block (15) forward and displaces a sear (29) to release the firing pin (20). The round is fired with its case virtually unsupported. On release of the trigger (6) the toggle mechanism (13, 14, 16, 17, 18) is bent so withdrawing the breech block (15) and the spent round which is automatically ejected. The firing pin (20) is simultaneously re-cocked. Rotary (2) and vertical stacking rechargeable magazines are described, from which a fresh round is automatically fed to the breech on ejection of a spent round.

Die Erfindung betrifft eine Pistole mit einem die Abzugseinrichtung aufweisenden Griffstück (1) und einem auf diesem gleitenden, den Lauf (4) und den Verschluß (5) enthaltenden Schlitten (2) sowie mit einer sich auf Griffstück und Schlitten abstützenden Rückholfeder (14), wobei der Verschluß mit einem von einer Schlagbolzenfeder (30) oder einem unter der Wirkung einer Hammerfeder (134) stehenden Hammer (131) antreibbaren Schlagbolzen (26) versehen ist und die Abzugseinrichtung einen in die Bewegungsbahn des Schlagbolzens bzw Hammers ragenden und im wesentlichen parallel zu dieser Bewegungsbahn geführten Anschlag (61 102 138) aufweist, der mittels eines Verbindungsstückes (64) mit dem Abzugshebel (63) verbunden und bei dessen Betätigung in Spannrichtung des Schlagbolzens bzw Hammers und unter deren Spannen bewegbar ist. Es ist eine Anschlagfeder (50. 109. 140) vorgesehen, welche einerseits im Griffstuck (1) und andererseits an der Abzugseinrichtung (51. 103, 137) angreift und deren Kraft nach Größe und Richtung das mittels des Abzugshebels (63) erfolgende Spannen der Schiagbolzenfeder (30) bzw. Hammerfeder (135) unterstützt.
摘要:
A firing pin block for a firearm of the type having a rotary breech bolt, a reciprocating bolt carrier, complementary locking lugs formed on the bolt and barrel to releasably secure them together, and cam means drivingly connecting the bolt and bolt carrier for opening and closing the bolt. The firing pin block positively prevents discharge of the firearm at any time when the bolt is unlocked. It does not rely on the presence or good condition of any separate parts, but instead coordinates the cam-actuated rotary operation of the locking lugs with relative longitudinal displacements between the bolt and bolt carrier, to cause the latter to block an enlarged abutment formed on the firing pin whenever the bolt is unlocked.
