摘要:
A storage and feed mechanism (10) stores ammunition (A) for a weapon (W) and facilitates feeding the ammunition to the weapon during firing. A magazine (12) comprises a storage chamber located adjacent the weapon and capable of storing a plurality of rounds of the ammunition. Individual rounds of ammunition are linked together on an ammunition belt (B) which carries the rounds to the weapon during firing. An ammunition feed (32) includes an inlet chute (33a) positioned above the magazine and allowing linked rounds of ammunition to be vertically extracted from the magazine thereby preventing tip-over and similar problems. The feed further includes a fixed fan section (32a) comprising a rigid chute through which the belt of ammunition is drawn. A sprocket drive (62) includes an appropriate gear (64) which engages the ammunition belt to draw the linked ammunition from the magazine up through the chute to the receiver. Use of the rigid chute minimizes resistance to movement of the ammunition belt and eliminates jams caused by belt stretching, and enables ammunition to be fed to the weapon regardless of the weapon's angle of elevation during firing.

Belted ammunition of either the "ball" or the shorter "SLAP" type is supplied through a flexible feed chute to a 7.62 mm mini machine gun using a specially configured feed adapter interconnected between the outlet end of the feed chute and the inlet of the gun feeder mechanism. The feed adapter, through which the ammunition passes into the gun feed mechanism, is provided with at least one internal roller around which the ammunition belt operatively passes. The roller has a side surface contour with a sloped shoulder portion which complementarily engages the sloping shoulders of the individual ammunition rounds passing around the roller. This complementary shoulder engagement longitudinally indexes the rounds within the adapter and limits undesirable longitudinal shifting of the rounds therein. In one embodiment thereof the adapter is connected to an aircraft plank-mounted mini gun and permits the ammunition belt to be routed over the gun, turned downwardly, and then bent sharply back into the gun's feeder mechanism without tending to cause ammunition jamming at the feed mechanism due to the sharp belt bend. In a second embodiment thereof the feed adapter is connected to a pintle-mounted mini gun and serves to provide improved vertical pivoting clearance between the gun and an aircraft door or window sill structure upon which the gun-supporting pintle apparatus is mounted. In a third embodiment thereof the feed adapter is connected to a pintle-mounted gun slidably mounted on a pivotable support arm member extending outwardly through an aircraft side door opening.

A cartridge belt guiding mechanism for automatic weapons disposed between the outlet of an ammunition belt storage container and the ammunition belt inlet of the automatic weapon. The guiding mechanism is composed of a plurality of open frame-like elements. Each element has a plurality of pins extending from opposite faces thereof. Coil springs are mounted on the pins and are connected to confronting faces of the frame-like elements. The coil springs define a flexible guide channel adapted slidingly guide therethrough the cartridges of the ammunition belt. The end elements of the channel are respectively connected to the outlet of the ammunition belt storage container and the ammunition belt inlet of the automatic weapon.

An RWS is configurable to adjust the height of a rotational elevation axis thereof by providing interchangeable pairs of removably mounted yoke arms, wherein the pairs have different heights. The RWS is provided with at least one fixed hanging ammunition container that is reloadable under the armored protection of the vehicle and the RWS shell.
摘要:
In the field of feeding ammunition to a firearm there is disclosed a flexible chute including successive sections (2) linked by portions of walls (111, 112, 131) at the transverse faces thereof and including at least one tubular section (2) of axis G with a first portion of wall (111, 112) integral with one of the two transverse faces thereof and a second portion (131) of wall integral with the other transverse face, characterized in that the projections of these portions of wall, perpendicular to a transverse plane of the section, are at least partially separate.
摘要:
The disc-type ammunition channel contains a predetermined number of discs or lamellae arranged adjacent one another and which can be rotated in a substantially cylindrical housing. The diameter of the discs or lamellae and of the cylindrical housing is smaller than the length of the cartridges to be passed therethrough. The tip ends of the projectiles of the cartridges protrude from the discs or lamellae into a housing member which is formed by two substantially helically shaped walls and a substantially cylindrical wall. Rotation of the discs or lamellae as a function of the elevation of the firing weapon is insured by a rod which is secured at one of its ends to a stationary housing member and at the other one of its ends to an elevatable housing member by means of rubber joints. The rod extends through elongated or oblong slots provided in the discs.
摘要:
An ammunition channel or chute is disclosed which is constituted by a multiplicity of juxtapositioned or adjacently arranged lamellae or plate-like elements which are interconnected by elastic elements. These plate-like elements are pivotally arranged between two end parts upon a shaft which is coaxially arranged with respect to the elevation axis of the weapon. The pivoting of one of the end parts, corresponding to the weapon elevation, is uniformly transmitted by means of the resiliently arranged elastic elements to the individual plate-like elements, so that there is ensured for a precise infeed of ammunition throughout each elevation angle of the weapon.
