摘要： A termination accumulator for a machine gun has a handling conveyor passing through a supply channel, a bypass channel, and a return channel. The supply channel leads to a feed system of a machine gun. The bypass channel has its other end connected to a return conveyor leading from the feed system. A gate is mounted at the junction of the bypass channel and supply channel operably between two positions, one position directs ammunition on the handling conveyor onto a supply conveyor leading to the feed system and a second position directs ammunition on the handling conveyor through the bypass channel. Upon release of a trigger mechanism operably connected to the gun, the gate moves from its first position to a second position such that the feed system continues its forward operation to clear itself of any live ammunition therein. The handling conveyor maintains a forward mode directing ammunition in to the bypass channel. A reversing mechanism reverses the handling conveyor to retrieve live ammunition from the bypass channel after the feed system is cleared of all live ammunition such that the live ammunition accumulated in the termination accumulator can be then fed to the feed system during the next operation of the machine gun.
摘要翻译：用于机枪的终端储存器具有通过供应通道，旁通通道和返回通道的处理输送机。供应通道导致机枪的进料系统。旁路通道的另一端连接到从进料系统引出的返回输送机。门在旁路通道和供应通道的连接处可操作地安装在两个位置之间，一个位置将处理输送机上的弹药引导到通向进给系统的供给输送机上，而第二位置通过旁通通道将处理输送机上的弹药引导。在释放可操作地连接到枪的触发器机构时，闸门从其第一位置移动到第二位置，使得进给系统继续其向前操作以将其中的任何实弹弹药清除。处理输送机保持向前模式将弹药引导到旁路通道。在进给系统清除所有实弹之后，反转机构反转处理输送机从旁路通道检索实弹，使得在机器的下一次操作期间累积在终端蓄能器中的实弹可以被馈送到进给系统枪。

摘要： This specification discloses an ammunition round and a method of firing the ammunition round. Consecutive and reproducible firing of a primer charge and a main propellant charge is accomplished as a result of the physical movement of a divider physically separating the primer charge from the main charge. Firing of the primer charge causes movement of the divider, initiates movement of a projectile within the ammunition round, and, when the combustion gases of the primer charge are in communication with the main propellant charge, causes firing of the main propellant charge.
摘要翻译：本说明书公开了弹药弹和弹药弹的方法。作为引物装料和主推进剂装料的连续和可再现的焙烧是通过物理分离引物电荷与主电荷的分离器的物理移动来实现的。引燃引燃器的引燃导致分隔器的移动，引发弹药弹中弹丸的运动，并且当引燃器的燃烧气体与主推进剂装药连通时，引起主推进剂装药的燃烧。

摘要： A buffered bolt assembly is disclosed for use in an automatic weapon. A b is received in a sleeve on a bolt carrier and is movable therein both axially and rotationally. One or more cam pins on the bolt are received in respective cam guides in the sleeve to control the bolt's rotational position as a function of its axial position. The aft end of the bolt is provided with at least one and preferably two aftward-projecting bolt extensions, for which corresponding slots are provided in the aft surface of the sleeve. When the bolt carrier and bolt are in the battery or firing position, the bolt extensions protrude through their respective slots. The bolt extensions are of such a length that during the recoil stroke of the bolt assembly, the aft ends of the bolt extensions are flush with the rear outer surface of the aft wall of the sleeve. When the rearward motion of the bolt carrier is stopped by the collision of the stationary buffer with the aft surface of the sleeve, the bolt extensions impact the buffer simultaneously with the sleeve, decelerating the bolt at the same rate as the bolt carrier. During the following forward stroke, the buffer also accelerates both the bolt and the bolt carrier simultaneously. As a result, the load on the latch and the cam pins is reduced.
摘要翻译：公开了一种用于自动武器的缓冲螺栓组件。螺栓容纳在螺栓承载件上的套筒中，并且可在其中轴向和旋转地移动。螺栓上的一个或多个凸轮销被容纳在套筒中的相应的凸轮引导件中，以根据其轴向位置来控制螺栓的旋转位置。螺栓的后端设置有至少一个并且优选地两个向后突出的螺栓延伸部，其中相应的狭槽设置在套筒的后表面中。当螺栓承载件和螺栓处于电池或点火位置时，螺栓延伸部分突出穿过其相应的槽。螺栓延伸部具有这样的长度，使得在螺栓组件的反冲行程期间，螺栓延伸部的后端与套筒的后壁的后外表面齐平。当固定缓冲器与套筒的后表面碰撞而阻止螺栓承载件的向后运动时，螺栓延伸部与套筒同时冲击缓冲器，以与螺栓承载件相同的速率减速螺栓。在下一个向前行程中，缓冲器同时加速了螺栓和螺栓承载件。结果，闩锁和凸轮销的负载减小。

摘要： A machine gun ammunition loading system employs cantilevered support memb on a magazine holding a leading round of belted ammunition supported above a cover of the magazine. The cover of the magazine includes mating parts which permit sliding engagement below the machine gun. When fully mated, the cantilevered members, with the leading round between them, are inserted into the receiver in a loading position from whence charging can be performed by single-handed motion of an operator while upright and walking.
