摘要： A safety cam pin assembly for replacing the standard cam pin of automatic rifles of the M-16 type, the safety cam pin assembly consisting of a modified cam pin and an obstruction safety bushing. The modified cam pin is the same as a standard cam pin with the exception that the lower portion of the cam pin shank is of reduced diameter by an amount equal to twice the wall thickness of the safety obstruction bushing, and a keyway is provided on the cam pin. The safety obstruction bushing is a sleeve which slips upward over the reduced lower portion of the modified cam pin and is provided with key elements to interfit with the keyway of the cam pin so that when the key and keyway are interfitted the bushing is rotatable with the cam pin. The sidewalls of the obstruction bushing are diametrically apertured with two sets of orthogonally disposed apertures, one set of such apertures being alignable with the firing pin aperture through the cam pin and of sufficient diameter to permit passage of the firing pin therethrough. The second set of apertures are of reduced cross section and do not permit passage of the firing pin entirely therethrough and thereby prevent the firing pin from reaching a round of ammunition when the cam pin has been omitted from the bolt assembly. Detent means are provided to retain the safety obstruction bushing in its firing pin obstructing position until such time as the cam pin is properly reinstalled into the bolt assembly.
摘要翻译：一种用于更换M-16型自动步枪标准凸轮销的安全凸轮销组件，安全凸轮销组件由改进的凸轮销和障碍物安全衬套组成。改进的凸轮销与标准凸轮销相同，除了凸轮销柄的下部的直径减小了相当于安全阻碍套管的壁厚的两倍的量，并且键槽设置在凸轮销。安全阻碍套管是一个套筒，其在修改的凸轮销的减小的下部向上滑动，并且设置有与凸轮销的键槽相配合的关键元件，使得当键和键槽配合时，衬套可以与凸轮销。障碍物衬套的侧壁是径向开孔的，具有两组正交设置的孔，一组这样的孔可以通过凸轮销与撞击销孔对准，并且具有足够的直径以允许击球通过。第二组孔径具有减小的横截面，并且不允许撞针完全通过其中，从而当凸轮销已经从螺栓组件中省略时，防止撞针达到弹药的一轮。提供止动装置以将安全阻塞套管保持在其击发销阻塞位置，直到凸轮销正确地重新安装到螺栓组件中。

摘要： Firearm apparatus embodied in a semi-automatic, blowback operated rifle. The firearm includes a receiver made of two plates spaced apart to receive a bolt mechanism including a bolt mounted for reciprocal motion within a channel-shaped member; the operating spring for the bolt assembly is received in a slot within the bolt and is retained in place by the channel-shaped member. A unitary firing pin/extractor carried by the bolt functions as a firing pin and also provides multiple extractor functions. A simplified firing mechanism includes a hammer positioned to the rear of a cartridge magazine and operatively connected by a three-finger sear bar to a trigger mounted in front of the magazine. A safety mechanism is provided in conjunction with the trigger guard. Numerous components of this firearm apparatus provide multiple functions contributing to the economy and efficiency of the present firearm apparatus.

摘要： A gas operated bolt carrier imparts reciprocating movement to a bolt body through a locking sleeve angularly displaceable on the bolt to a striker blocking position thereby preventing firing when the bolt is displaced from its battery position. A locking slot formed in the receiver prevents angular movement of the locking sleeve following initial retraction of the bolt from the battery position by the bolt carrier.

摘要： An automatic firearm incorporates a shock absorber in which a buffer spring is accommodated in a bore in the breech block and bears at one end against a buffer member which is supported by means of a slider to which the buffer movement is imparted and which extends transversely to the direction of movement of the buffer member and is accommodated in a slot in said member. Preferably the buffer spring encloses a striker pin the end of which is exposed in the slot and adapted for operation by a hammer for initiating firing of the weapon.

摘要： A firearm capable of firing ammunition of the caseless-type The firearm has a bolt carrying a firing pin and an obturator which is slidably supported by the barrel of the firearm. The obturator is provided with a radial extending wall and the pressure of the gas within the chamber, when a round of caseless ammunition is fired, forces the obturator into tight engagement with the bolt to prevent gas leakage. The obturator also has a circumferentially extending wall of relatively thin radial dimension which is forced against the barrel when the round of caseless ammunition is fired. A ratchet-and-pawl arrangement is provided connected with the obturator and as the bolt is opened and closed and rotated during these operations the obturator is rotated in one direction. The bolt has a bore containing a firing pin seal disposed about the firing pin. This seal has an end portion formed with an axially extending groove to provide inner and outer circumferentially extending lips. These lips are expanded respectively against the bore wall of the bolt and a portion of the firing pin when a cartridge is fired to prevent gas leakage. The firing pin includes a shaft of steel material having a firing tip formed of a refractory material such as a tantalum alloy.
摘要翻译：能够发射无内胎类型的弹药的枪支枪械有一个螺栓，带有一个可以由枪支枪管可滑动地支撑的撞针和闭孔器。闭孔器设置有径向延伸的壁和腔室内的气体的压力，当一无形弹药被点燃时，迫使填塞器与螺栓紧密接合以防止气体泄漏。闭孔器还具有相对薄的径向尺寸的周向延伸的壁，当圆形无弹药弹射时，该壁壁被迫靠在枪管上。棘爪和棘爪布置被设置成与闭孔器连接，并且当螺栓在这些操作期间打开和关闭并旋转时，闭孔器在一个方向上旋转。螺栓具有包括围绕撞针设置的撞针密封件的孔。该密封件具有形成有轴向延伸的凹槽的端部，以提供内周和外周向延伸的唇部。当筒被点燃以防止气体泄漏时，这些嘴唇分别膨胀在螺栓的孔壁上和一部分撞针上。射击销包括具有由诸如钽合金的耐火材料形成的点火尖端的钢材的轴。
