摘要： Reliability of a multi-lug breech bolt is improved by modifying the bearing relationship between the bolt lugs and the matching lugs within a gun receiver. This procedure is applied to a gun that has a receiver housing a breech bolt and an extractor. The extractor is coupled to the breech bolt and configured to move relative thereto. The bolt for this gun has at least five radially extending bolt lugs configured for bearing contact with the receiver when positioned for firing. The bolt lugs include a first, second, and third bolt lug with the first and second bolt lugs being adjacent and defining a gap configured to receive the extractor therebetween. The third bolt lug extends from the bolt opposite the gap. Stress imparted to the first and second bolt lugs from firing the gun is reduced by altering the gun to prevent formation of a bearing relationship between the third bolt lug and the receiver when the bolt lugs are positioned for firing. The gun is reassembled as part of the procedure. The alteration may be accomplished by removing material from the third lug, a corresponding lug of the receiver, or both.

摘要： A tubular automatic weapon includes a barrel having a rear terminal portion defining a chamber, and a breech block having a breech block axis and being arranged for movement in axial alignment with the barrel. The breech has a block housing, a rotary head; an iron core secured within the head; a permanent magnet situated within the head and being movable relative to the iron core in inductive relationship therewith; an energy accumulator for storing the kinetic energy derived from the motion of the housing towards a rearward position; and a coupling arrangement for connecting the energy accumulator with the permanent magnet to cause the permanent magnet to be propelled forwardly relative to the iron core by the energy released by the energy accumulator, thereby generating a magnetic field for inducing an igniting current in a cartridge situated in the chamber.

摘要： A repeating firearm includes a bolt carrier and bolt assembly which are movable relative to each other to provide for locking and unlocking the bolt with respect to the barrel breech. An elongated bearing plate is supported by the bolt and movable with the bolt to maintain a cartridge to be next inserted into the barrel chamber in a predetermined position until the bolt is substantially fully retracted to prevent premature movement of the cartridge upon movement of the bolt carrier only. The bolt carrier and bolt assembly are interconnected by a cam mechanism including a helical cam slot formed in the bolt carrier and a cylindrical pin type cam follower engageably with the bolt. The bolt, cam follower and an elongated firing pin are maintained in assembly with the bolt carrier by a firing pin retainer which is locked in a pin retaining position by a movable member which permits movement of the firing pin retainer at will to release the firing pin for removal from the bolt assembly without complete removal of the pin retainer from the bolt carrier. A bolt lockout pin includes an actuating lever mounted on a support plug which may be reversibly mounted on the stock section for interchanging the lever from one side of the stock section to the other.

摘要： A gun mount having a gun cover or shield contains a gun which may be directed in both azimuth and elevation. An ammunition storage space is disposed below the gun mount. Ammunition components are combined in the storage space to provide an ammunition round with the long axis of the round substantially vertical. The barrel of the gun is elevated to the 90.degree. or vertical position and when the breech block is opened the vertically disposed ammunition round is hoisted directed into the open breech. The round is latched in the breech while the hoisting mechanism is withdrawn and the breech is closed. Thereafter the gun may be depressed to a desired firing elevation and the round fired. The gun is then positioned at a predetermined intermediate elevation angle so that the gun breech is adjacent to a door in the gun cover which is controlled between open and closed positions. The breech is opened, the door is opened and the empty propellant case from the fired round is ejected through the open door. The gun is then repositioned to the vertical position to receive another round in the breech and the process is repeated. Conventional length ballistic projectiles and ultra-long guided projectiles may be handled by the disclosed loading system and the loading may be accomplished at any angle or azimuth or train.

摘要： A bolt latch for use in a firearm having a rotary locking system in which the latch locks the rotational movement of the bolt at all times during the cycle of operations of the gun except during locking and unlocking of the bolt head with the barrel extension.The bolt latch is pivotally mounted to the bolt carrier for movement perpendicular to the axial movement of the bolt and is spring biased outwardly into bolt blocking position wherein the bolt cannot move relative to the bolt carrier and thus rotation of the bolt is prevented. The bolt latch is actuated into non-blocking position (i.e. rotation of the bolt is permitted) as the bolt approaches the breech-closed position by a cam means on the firearm.

摘要： An automatic gun is provided with a reciprocating bolt carrier having cam surfaces extending along its exterior for reciprocating a follower which operates an ammunition feed mechanism. A lower cam surface is formed directly on the bolt carrier and an upper cam surface is formed on the upper surface of an elongated ramp pivotally mounted on the bolt carrier. The ramp is movable between two positions to cause the follower to follow the lower cam surface when the bolt carrier moves forwardly and to follow the upper cam surface when the carrier reverses. The slope of the cam surfaces is such that the follower moves through its total downward return stroke when engaging the forward portion of the lower cam surface and then is gradually advanced upwardly during the remainder of its contact with the lower cam surface and throughout its entire contact with the upper cam surface.
