摘要： Firearms with cartridge-case ejection, including a barrel with a movable bolt carrier with a bolt, with a breech face, with a movable ejector and with a firearm-fixed functional edge which pushes the ejector into its ejection position when the bolt carrier moves back after a shot has been fired. In order to create an ejection that is always evenly performed, an ejector lever is arranged on the bolt carrier so that it can be rotated about a pivot axis running normal to the firearm's central plane, which abuts against the functional edge when the bolt carrier moves backwards and thereby twisted so that it abuts an impact surface of the ejector and forces it to the eject position.

摘要： Applicant has disclosed a method and apparatus to enhance feeding cartridges into the receiver of a bolt-action repeating rifle, from a detachable magazine. In the preferred embodiment, Applicant's invention strips the cartridges from the magazines and feeds the cartridges into the chamber by a spring-activated hinged flap, pinned in a mating recess in a breech bolt head, adjacent a well opening and the inserted magazine. The flap is biased by a spring, which tends to lower the flap away from the breech bolt head, when the breech bolt is in a retracted position. As the breech bolt is pushed forward, the flap engages a rim of the next cartridge to be fed from the magazine and pushes the cartridge out of the magazine, over a feed ramp of the magazine, towards the rifle's chamber. The flap raises, against spring pressure, as it contacts a feed ramp of the receiver, allowing the breech bolt to enter the locking area of the receiver.
摘要翻译：申请人已经公开了一种方法和装置，用于从可拆卸的盒子中将进料筒增强到螺栓动作重复步枪的接收器中。在优选实施例中，申请人的发明从盒中剥离盒，并且通过弹簧活动的铰接翼片将盒子送入室中，该铰链翼片固定在后膛螺栓头部中的配合凹槽中，邻近井口和插入的盒。当臀部螺栓处于缩回位置时，翼片被弹簧偏压，该弹簧倾向于使翼片远离后膛螺栓头部。当后膛螺栓向前推动时，翼片接合下一个盒的边缘，以从盒中进给，并将盒从盒的进料斜坡推出仓库朝向步枪室。当弹簧接触接收器的进料斜坡时，挡板弹簧压力升高，允许后膛螺栓进入接收器的锁定区域。

摘要： A firearm includes a bolt mechanism with a bolt configured to receive a firing pin assembly and a bolt head assembly. The bolt head assembly includes a pivoting bolt head and an extractor. The extractor is positioned relative to the bolt such that substantially all forces applied by the extractor to the bolt mechanism are reacted within the bolt head assembly. A biasing member or element can urge a claw portion of extractor towards a distal end of the bolt head.

摘要： A barrel adaptor for a single-shot break-action firearm comprises a barrel stub and an extractor. The barrel stub comprises a main body and a mounting lug. A barrel-receiving bore extends through the main body and can threadedly receive a barrel. Opposed parallel extractor channels are formed between the barrel-receiving bore and the locking bolt receptacle, substantially parallel to the barrel-receiving bore. An extractor head recess at the breech end of the main body extends into the barrel-receiving bore and into the lug, merging with the extractor channels to form an extractor receptacle. The extractor comprises an extractor head having an arcuate cartridge-engaging lip and opposed, spaced apart substantially parallel extractor arms received in the extractor channels. The extractor is longitudinally movable between a firing configuration where the extractor head is in the extractor head recess and an extended configuration where the extractor head is withdrawn from the extractor head recess.
