Abstract: A helical storage system for linked ammunition, has no outer drum and only two moving parts, providing positive control of the rounds, low friction, and bi-directional load and unload.

Abstract: A gun system is provided which includes a Gatling type gun having a housing with a ring gear, a rotor with a cluster of gun barrels, a gun gas drive mechanism with a cylinder, a piston, and a crank with a pinion meshed with the ring gear.

Abstract: A gun system is provided which includes a Gatling type gun; a barrel cluster having a torque assist device and coupled to a hydraulic starting subsystem to provide initial acceleration, rotational velocity control, braking and reverse clearing of the gun; and a gun gas drive to provide steady-state energy for rotation of the barrel cluster.

Abstract: This invention provides an enclosure for a naval gun turret having static seals around the access covers and dynamic seals around the gun barrel slot closure, which seals capture and drain off to a sump any leakage within the interfaces or joints of the main body with the covers and the closure to preclude entrance of wind driven rain or seawater into the interior of the enclosure.

Abstract: A feature of this invention is the provision of a train of round carriers, adapted to come from a stationary supply, each carrier coupled to the next adjacent carrier by pivot means capable of unrestricted rotation, and each carrier carrying a respective round of ammunition; and a rounds orientation means, adapted to rotate in train as a function of the rotation in train of a gun and to intercept and orient each assembly of carrier and respective round, by rotation of its respective pivot means, to an orientation in train which is determined by the orientation in train of the gun.

Abstract: A feature of this invention is the provision of a three axis gun mount wherein the gun is mounted for movement in elevation and in train (azimuth) with respect to a platform which is disposed in a plane which is at an angle to the horizontal and which platform is mounted for movement about the zenith axis.An additional feature of this invention is the provision of such a mount wherein said platform is provided with unlimited rotation in either direction about the zenith axis.A yet additional feature of this invention is the provision of such a mount wherein the three axes of the mount, and the axis of the gun along which the firing impulse is applied to the mount, all have a common intersection.

Abstract: A feature of this invention is the provision of sprocket which feeds rounds into the gun via an intermediate sprocket and which receives cases from the gun via another intermediate sprocket, and which may be intercoupled with either of two endless conveyors of ammunition.

Abstract: A feature of this invention is the provision of side stripping stripper which has a sprocket mechanism disposed on the closed side to positively drive both the rounds of ammunition and the respective links during the stripping operation.Another feature of this invention is the provision of a mechanism for receiving two feeds of linked ammunition and which has two, mutually interlocked, sprocket mechanisms, each disposed on the closed side of a respective feed of linked ammunition, so that one or the other sprocket mechanism is enabled to positively drive both the rounds of ammunition and respective links during the stripping operation of the selected feed of linked ammunition.

Abstract: A feature of this invention is the provision of a Gatling type gun having a firing/safing cam assembly having three dispositions: one permitting firing in one direction of rotation; another permitting firing in the other direction of rotation; and yet another precluding firing in either direction of rotation of the rotor.

Abstract: This invention has the provision of a magazine having an endless conveyor comprising a plurality of links, each having a respective element for releasably capturing the extractor disk of a cartridge case.

Abstract: This invention provides for a feeder tray which is journaled for rotation on a longitudinal axis and which includes two longitudinally extending cutouts, one for receiving fresh rounds of ammunition in sequence from a constant velocity train of ammunition and for transferring each round to the face of the gun bolt in aft dwell, the other for receiving the fired case and for displacing the fired case from the face of the gun bolt, and driven by a cylindrical cam system.

Abstract: An igniter assembly for use in liquid propellant guns comprises an outer tubular conductor and an inner conductor spaced apart by a volume of tightly packed, irregular granules of an insulating material, such as a mineral powder. The outer conductor is supported in a longitudinal bore of a gun bolt.

Abstract: A mechanism is provided to detect the occurrence of a misfire in an automatic gun and for thereupon halting, prior to the unlocking of the gun, the further operation of the gun; which is particularly adapted to liquid propellant guns having a rotating drum.

Abstract: An L-shaped seal, for a gun firing caseless ammunition, is captured in and to the chamber of the gun, and is preseated against the surface of the bolt by plastic deformation effected as the gun bolt is rammed into the chamber.
