Abstract: A method and apparatus are disclosed for the measurement of tension in a stretched elastic surface. The apparatus includes a rigid housing having at least two diametrically opposed sides and a spring device contained therein with a contact member connected to the spring device which protrudes a predetermined distance outwardly beyond the ends of the housing sides when the spring device is in a resting state. Measuring and display devices are connected to the spring device for measuring the spring deflection when the housing is pressed against an elastsic surface. The housing is placed adjacent the elastic surface to be measured with the contact member in contact with the elastsic surface such that a fixed distance exists between the ends of the housing sides and the surface prior to application of a pressing force. The housing is then pressed against the elastic surface until the ends of the housing sides come into contact with the surface such that the spring device is deflected. The deflection is measured and displayed as an indication of the tension in the elastic surface. In one embodiment the spring device is a cantilever beam with the measuring device being at least one strain gauge mounted thereon. In another embodiment, the spring device is a coil spring with the measuring device being a linear variable differential transformer.

Abstract: An ammunition feed mechanism for a machine gun includes a sprocket having rtridge feeding and positioning splines. This sprocket rotates in a feed direction to move a belt of linked cartridges into position for chambering and firing. An anti-backup pawl prevents counterrotation and maintains the sprocket in position while a cartridge is chambered. A ratchet release permits bidirectional rotation of the sprocket in loading and unloading of the ammunition belt. The rotation of the sprocket for feeding is done with a cam tube actuator making a ratchet connection with the sprocket. The reciprocating movement of the bolt carrier causes rotary movement of the actuator by means of a pin on the bolt carrier riding in the cam of the actuator. The bolt carrier has a depressible rammer for chambering the cartridges. This permits the bolt carrier to override a subsequently positioned cartridge during carrier recoil instead of the conventional recoiling of the carrier before subsequent moving of the next cartridge to its feed position.

Abstract: There is disclosed a gas operated, fully automatic weapon system with a d feed mechanism having a long recoil, soft cycle operation. The automatic weapon system consists of six groups or sub-assemblies. These are the backplate (rear end cap/fire control assembly), the dust cover unit, the dual selective rotary feed unit, the operating group unit, the receiver unit, and the barrel unit. These sub-assemblies combine to provide a weapon characterized by lightness of weight, relatively slight recoil force, relatively slow gunfire rate, excellent manual control resulting in good burst fire accuracy in hitting targets, and safety during operation and disassembly.
