摘要： A mechanical tight cartridge casing release of the invention is preferably for inclusion with a large cartridge rifle bolt and includes a pivot mounting of a rifle bolt arm or handle to the bolt whereby, after the arm or handle is moved to an unlocked position, an application of a force to the arm or handle end wil pivot that arm or handle relative to the bolt surface such that an arm or handle forward shoulder engages a surface of the rifle receiver producing a lever action and providing a mechanical advantage to the force applied by an operator or shooter that arm or handle to "break loose" the spent cartridge casing from the barrel chamber, with the bolt to then be moved rearwardly to where the casing is ejected. The relationship of the distance from the bolt handle end that is pulled by the operator or shooter to the arm or handle pivot and the distance from the pivot to the handle forward shoulder is selected to provide a desired mechanical advantage whereby a pulling force as is exerted through the arm or handle is increased to "break loose" the spent cartridge casing that will have expanded in the rifle chamber when the cartridge is fired.
摘要翻译：本发明的机械密封筒壳体释放优选地包括大型筒式步枪螺栓，并且包括将步枪螺栓臂或手柄枢转安装到螺栓，由此在臂或手柄移动到解锁位置之后，应用对臂或手柄端部的力的相对于螺栓表面枢转该臂或手柄，使得臂或手柄前肩接合步枪接收器的表面产生杠杆作用，并且对由操作者或射手，其手臂或手柄将“用户筒”从“筒室”松开，然后将螺栓向后移动到套管弹出的位置。选择由操作者或射手拉动到手柄或手柄枢轴的螺栓手柄端的距离和从枢轴到手柄前肩的距离之间的关系，以提供期望的机械优点，由此施加的拉力通过手臂或把手被增加到“松开”当筒被点燃时将在步枪室中膨胀的用过的筒壳体。

摘要： A breech block has, for each cheek of a breech ring, at least one bearing surface facing a rear of the breech. The bearing surface is adjustable to slide along a paired bearing surface of a matching bearing element of the cheek and bears on the paired bearing surface to transfer strain to the cheek generated during firing of a round. The bearing surface of the breech block and the paired bearing surface of the cheek of the breech ring face each other so that the plane of each of the matched bearing surfaces intersects a plane defined by the axis of the barrel and a horizontal line along a half-line terminating at the axis. The half-line defines an angle greater than 90.degree. with respect to the axis.
摘要翻译：对于臀部环的每个脸颊，后膛块至少有一个面向后膛后方的支承面。轴承表面是可调节的，以便沿着面颊的匹配轴承元件的一对支承表面滑动，并且承载在成对的支承表面上，以将应变转移到在一个圆形的发射期间产生的面颊。后膛块的支承表面和后膛环的脸颊的一对支承表面彼此面对，使得每个匹配的支承表面的平面与由枪管的轴线限定的平面相交，沿着一半的水平线相交线在轴处终止。半线定义相对于轴大于90°的角度。

摘要： The invention comprises an improved recoil control device comprising a bolt head and an inertia block or slider for use in a variety of firearms. In one embodiment, the bolt head and inertia block are articulated so that the displacement of the bolt head results in a force component outside the firing axis of the barrel of the firearm. The device can be incorporated into firearms of a variety of sizes and configurations to produce recoil reduction and/or weight reduction advantages.
摘要翻译：本发明包括改进的反冲控制装置，其包括用于各种火器的螺栓头和惯性块或滑块。在一个实施例中，螺栓头和惯性块被铰接，使得螺栓头的位移导致在枪支的枪管的击发轴线外部的力分量。该装置可以并入到各种尺寸和构型的火器中以产生反冲降低和/或减轻重量的优点。

摘要： A weapon for firing cased telescoped (CT) ammunition includes a barrel, a chamber member and a carrier assembly. The chamber member defines a chamber for a CT round for firing, and translates between a firing position aligned with the barrel and an ejection/loading position. The chamber member is spring-biased toward the firing position. The carrier assembly carries the firing pin and (1) performs a recoil in which a carrier and rammer move rearward from a battery position to bring the next CT round into a ramming position and to move the chamber member from the firing position to the ejection/loading position, and (2) performs a counter-recoil to return to the battery position and cause the rammer to push the next CT round into the chamber. The chamber member is released for biased return to the firing position for a next firing cycle.
