摘要： A gun including a barrel assembly feed (19) for advancing a plurality of barrel assemblies (14) of the type having a plurality of projectiles stacked axially within each barrel assembly (30) together with discrete selectively ignitable propellant charges for propelling the projectiles from each barrel assembly (30), the plurality of barrel assemblies (14) being linked together in spaced apart parallel relationship (15) and locating one or more barrel assemblies (30) in a firing station wherein the firing station operatively supports the one or more barrel assemblies (30), the gun further including a charge initiator associated with the firing station for selectively initiating said discrete selectively ignitable propellant charges of one or more barrel assemblies (30) operatively supported by the firing station. The barrel assembly (30), has an inner barrel (32) made of a hard, non-deformable material and an outer casing (33) of a ductile material. The outer casing may be deformed by the slots (20) and sprocket teeth (21) of a sprocket drive.

摘要： The invention relates to a rifle breech box and the firearm resulting therefrom. The breech box (11) comprises at least one channel (6) corresponding to at least one barrel (7), a pre-firing chamber (3) into which a cartridge is inserted prior to firing and from which the associated case is ejected after firing, a breechblock (1) and associated closing means (5), a firing pin (2), a trigger (10), means (8) for constraining the firing pin (2) and the trigger (10), able to ensure that the firing pin (2) is released when the trigger (10) is pressed, and movement transmission means (9) which are located between the trigger (10) and the means (5) for closing the breechblock (1) and are able to ensure that the closing means leave the breechblock (1) free to return into the rest position, allowing ejection of the case following pressure on the trigger (10). The firearm obtained therefrom may also be semi-automatic, in the sense that two barrels (7) may also be provided on the same firearm, one operating repetitively and the other in the manner indicated according to the present invention.
摘要翻译：本发明涉及步枪后膛和由此产生的枪支。后枪盒（11）包括至少一个对应于至少一个枪管（7）的通道（6），预燃烧室（3），在燃烧之前将筒插入其中，并且相关联的壳体从其中被喷射触发器（1）和相关联的关闭装置（5），击发销（2），触发器（10），用于约束击发销（2）和触发器（10）的装置（8），能够确保当触发器（10）被按压时，触发销（2）被释放，以及位于触发器（10）和用于关闭后膛（1）的装置（5）之间的移动传动装置（9）以确保关闭装置离开后膛（1）自由返回到静止位置，允许在触发器（10）上的压力下弹出壳体。由此获得的枪支也可以是半自动的，这意味着两个桶（7）也可以设置在同一个枪支上，一个反复操作，另一个按照本发明所示的方式操作。

摘要： A bolt assembly (10) is provided for a double-barrel repeating firearm (1), such as a rifle or a shotgun. The bolt assembly is adapted to fit in the receiver (30) of the double-barrel firearm. The bolt assembly comprises a bolt body (70) which connects to first (86a) and second (86b) breech bolts, and which also couples to a bolt collar (72). The bolt collar has a bolt handle (74) for operating the bolt assembly. The bolt body and breech bolts have recesses for accepting first (90a) and second (90b) firing pin assemblies. The firing pin assemblies include first (102a) and second (102b) cocking pieces, which are both cocked by the action of the bolt collar. Once cocked, the cocking pieces can be released independently of each other for firing using the trigger (62). Pulling the bolt assembly rearwards ejects the fired cartridges through an ejection port (56a,b) on the receiver. The receiver also includes a cartridge injector port (58a,b) which couples to a magazine (50) capable of storing additional cartridges (C3,C4). During the forward travel, the bolt assembly reloads the firing chambers with cartridges from the magazine.
摘要翻译：为双筒重复枪支（1）提供螺栓组件（10），例如步枪或霰弹枪。螺栓组件适合于安装在双筒枪支的接收器（30）中。该螺栓组件包括连接到第一螺栓（86a）和第二螺栓（86b）并且还连接到螺栓套环（72）的螺栓主体（70）。螺栓套环具有用于操作螺栓组件的螺栓手柄（74）。螺栓主体和后膛螺栓具有用于接纳第一（90a）和第二（90b）撞针组件的凹部。撞针组件包括第一（102a）和第二（102b）扳起件，它们都被螺栓套环的作用扳起。一旦翘起，可以使用扳机（62）将翘起的部件彼此独立释放以便发射。向后拉动螺栓组件将通过接收器上的弹出端口（56a，b）弹出燃烧的弹夹。接收器还包括耦合到能够存储附加盒（C3，C4）的盒（50）的盒注入口（58a，b）。在前进行驶过程中，螺栓组件会使用弹匣中的弹药筒重新装载燃烧室。

摘要： A two-barrel gun for firing two types of ammunition includes a single breech locking mechanism for both barrels. The gun includes a selector lever for activating one of two bolts associated with the two barrels, and a single trigger for firing ammunition from a chamber associated with the activated bolt. The gun further includes two magazines for feeding ammunition to the chambers, and a pump-action forearm for ejecting spent ammunition and for loading a new round of ammunition into the chamber associated with the activated bolt. The single breech locking mechanism extends forwardly of the chambers, and the actual breech locking engagement occurs in front of the bolts. Therefore, the receiver section of the gun can be made more compact, and can more easily accommodate other essential components.
摘要翻译：用于发射两种弹药的两枪枪包括用于两个炮弹的单个后膛锁定机构。枪包括用于激活与两个筒相关联的两个螺栓中的一个的选档杆，以及用于从与激活的螺栓相关联的室中发射弹药的单个扳机。枪还包括两个用于向各室提供弹药的杂志，以及一个泵动前臂，用于弹出已用的弹药，并将新一轮的弹药装载到与活塞螺栓相关的腔室中。单个后膛锁定机构在腔室的前方延伸，并且实际的后膛锁定接合发生在螺栓的前面。因此，枪的接收器部分可以制造得更紧凑，并且可以更容易地容纳其他基本部件。
