Abstract: An ammunition magazine, including a container configured to hold ammunition and dispense the ammunition to a weapon, and an indicator disposed in the container and configured to create a signal indicative of a predetermined amount of ammunition remains in the container. In one example embodiment, the indicator includes a sensor member configured to engage with the ammunition when more than the predetermined amount of ammunition remains in the container, and configured to not engage with the ammunition when less than the predetermined amount of ammunition remains in the container. A signal generator is coupled to the sensor member and configured to provide an electrical signal indicative of whether the sensor member is engaging the ammunition, or is not engaging the ammunition.

Abstract: A mechanical gun charger configured to charge a gun, including a cradle configured to support the gun. A lever is rotatably coupled to the cradle, wherein an outboard cable coupled between the lever and a first pulley is configured such that displacement of the lever causes the first pulley, a shaft, and a second pulley to rotate. A charging cable is coupled to the second pulley and is configured to couple to and charge the gun upon rotation of the second pulley.

Abstract: Armament apparatus is provided for an aircraft having an interior area. The armament apparatus includes a horizontally disposed, generally plank-shaped elongated support beam member having top and bottom sides, a longitudinally intermediate section extending transversely through the interior area, and an outer end portion extending outwardly beyond an exterior side of the aircraft and having top and bottom sides and laterally opposite side edges. The outer support beam end portion, along at least a substantial portion of its length is laterally narrower than the intermediate section of the support beam member. This permits a crew member to sit on the support beam member, with his legs outside the aircraft and downwardly straddling the outer support beam end portion, and operate a crew-served weapon on the top side of the outer end portion of support beam member.

Abstract: A remotely operable machine gun charger is provided for selectively controlling the forward-to-rear movement of a machine gun bolt pin. When the bolt pin is released from its safe position the charger permits the bolt pin to be spring-driven back to its armed position substantially instantaneously by the bolt spring without waiting for pin engagement and drive structure portions of the gun to be returned to their forwardmost positions. The charger permits the gun to be fired during such movement of the engagement and drive structure back to their forwardmost positions, and the charger may be mounted on and removed from the machine gun without the use of tools, or the necessity of removing or adjusting any of the internal components of the machine gun.

Abstract: An ammunition magazine box is provided for receiving a vertically serpentined length of belted ammunition for selective outfeed from the box to a machine gun. A specially designed support bracket structure, representatively of a length adjustable construction, is provided and suitably secured within the interior of the magazine box. At least a portion of the belted ammunition loops rest on a top side surface of the installed support bracket structure. The top support bracket structure side surface is (1) laterally sloped, in a direction transverse to the lengths of the belt loops, to inhibit a tilting-created intermeshing of vertically adjacent projectile ends of the ammunition rounds which could cause a feed jam, and/or (2) longitudinally sloped, in a direction parallel to the lengths of the belt loops, to desirably lessen the ammunition outfeed force that must be exerted by the machine gun.

Abstract: To safely and reliably hold the forwardly spring-biased bolt assembly of a machine gun in a rearwardly disposed position within the receiver portion of the gun, a specially designed locking apparatus is mounted on an exterior side surface portion of the receiver. The locking apparatus has a slot therein which is operative to rearwardly receive a bolt pin portion of the bolt assembly which is anchored to the bolt assembly for reciprocating motion therewith and projects outwardly through a sidewall slot in the receiver for reciprocating motion with the bolt assembly. To releasably lock the bolt assembly in its rearward position the bolt pin is rearwardly moved into the locking apparatus slot, and a latch portion of the locking apparatus is moved to block forward exit of the pin from the locking apparatus slot.

Abstract: A single pintle arm-based structure is provided for mounting a machine gun on the exterior of a helicopter fuselage on the frame of or adjacent a gunner's cabin area side wall opening such as a window or door. The mounting structure permits horizontal pivotal motion of the single pintle arm and gun among lockable service, stowed, crew-served and full forward positions. The gun and the mounting structure, in their stowed position, are disposed externally of the helicopter, thereby permitting of the fuselage side wall opening, with the pintle arm being pivotable about an axis external to the fuselage.

Abstract: An ordnance mounting system for a helicopter operatively supports a weaponry support beam above an upwardly projecting floor obstruction in a cabin area of the helicopter, between opposite cabin door openings, with the support beam longitudinally extending transversely through the cabin area, and outer weaponry mounting end portions of the support beam projecting outwardly through the door openings beyond opposite fuselage side walls of the helicopter. The mounting system may be secured to door opening sill structures, or the cabin ceiling or side walls, and permits vertical bending flexure of the installed support beam due to flight and weaponry weight loads on the outer ends of the support beam.

Abstract: A weapon, representatively a machine gun, is mounted in a crew-served orientation on the outer end of an elongated support beam extending transversely through and secured within the cabin area of a helicopter, with the outer beam end disposed exteriorly of the helicopter. A seat structure, upon which a crew member may sit, is mounted atop a longitudinally central portion of the beam for sliding movement along the beam toward and away from the machine gun. Operatively associated with the machine gun is an ammunition box having a lid portion fixed to the bottom side of the beam end upon the top side of which the machine gun is pivotally and rotationally mounted. The body of the ammunition box is removably securable to the beam secured lid.

Abstract: An aircraft object mounting system is formed from three light weight honeycombed metal plank sections—a longitudinally central section and a pair of upturned end sections removably secured thereto. The end sections have bomb racks thereon to which various weaponry, such as machine guns, rocket launchers or missiles, may be attached. The central section is secured to the underside of a helicopter, with small lug structures on the central section extending upwardly into the aircraft cabin area and secured to bulkheads therein. The object mounting system is thus positioned essentially entirely externally to the aircraft and only minimally intrudes into the interior thereof. The mounting system may be used to support non-weaponry objects, and may be utilized with aircraft other than helicopters.
