摘要： A guide system for the recoiling mass of a gun relative to its cradle, the recoiling mass being equipped with a carrier that slides relative to sliders attached to two lateral slides. The carrier is provided with a rail incorporating a groove in which a slider is disposed. Each groove has a shape preventing the slider received therein from being extracted from it. Each slider is attached to a support. The combination of carriers and sliders is adjustable relative to the slides, by the supports, to compensate for wear.

摘要： An automatic pistol, with at least a barrel (1) and a slide (2) that move relative to the rest of the firearm and to each other, whereby the barrel extends through an alignment channel (3) in the slide. The weapon included means (4) of centering the barrel around at least one axis through the slide such that the barrel will not jam. The means are elastic and resilient and rest lightly against the inner surface of the channel before the weapon is discharged.

摘要： A heavy support weapon, for example, of 30 mm caliber, designed for firing from conventional machine gun mounts without undue recoil loads transferred to the gun mount. The weapon is designed for first round accuracy whether in the automatic open bolt or semi-automatic closed bolt mode. The weapon 10 includes a barrel 13 joined to a barrel yoke 21 in a receiver 14 aft of a front housing assembly 15. The recoil system includes a main recoil spring 30, a secondary spring 23, a buffer group including rods 60, springs 61 and plate 63. A slide bolt assembly 40 includes a slide 41, a bolt 42, a face 43, bolt face levers 44 and actuating pins 45, all within the receiver 14. The bolt face 43 is driven vertically by the bolt face levers 44 to receive a new round, load it and remove and discharge a spent casing. The slide bolt assembly 40 travels forward and aft during the firing cycle. On rearward travel it is accelerated rearward by accelerator 70 until reaching the buffer group and transfers its kinetic energy to the buffer group which in turn transfers that energy to the barrel 13 and the recoil spring 30 where it is absorbed without transferring the impact loading to the weapon mount.
摘要翻译：一种重型支撑武器，例如30毫米口径，设计用于从常规机枪安装座射击，而不会有不适当的反冲载荷转移到枪支架上。无论是在自动开启螺栓还是半自动闭合螺栓模式下，武器都是第一轮精度设计的。武器10包括在前壳体组件15的后部接收器14中连接到筒状轭21的筒13.反冲系统包括主反冲弹簧30，次弹簧23，包括杆60的弹簧61和弹簧61 滑动螺栓组件40包括全部在接收器14内的滑动件41，螺栓42，表面43，螺栓面杆44和致动销45.螺栓面43由螺栓面杆44垂直地驱动到接收新的一轮，装载它，并移除和排出废旧的套管。滑动螺栓组件40在点火循环期间向前和向后行进。在向后行进时，其被加速器70向后加速，直到到达缓冲组并将其动能传递到缓冲组，缓冲组又将该能量转移到筒13和反冲弹簧30，在其中被吸收而不将冲击载荷转移到武器装载

摘要： A handgun frame is provided for receiving a barrel and slide of the type operating on the Browning short recoil principle. The frame includes a magazine well defined within a grip formation. An elongated cantilever support extends forwardly from the grip formation to a position beyond a forward end of the barrel. A barrel bushing is rigidly fixed to and directly mounted on a forward end of the cantilever support for slidably supporting a front end of the barrel therein. Slide support means slidably support the slide.
