Abstract

A machine gun top cover assembly includes a top cover door attached to a main housing. The top cover assembly defines a rear transverse track section and a front transverse track section for guiding bolt assemblies of the gun. As the machine gun rotor assembly rotates, the rear track section prevents the bolt assemblies from moving into position for firing, and the front track section guides the bolt assemblies into position for firing. A selector switch on the top cover door selects between: (i) a safe position wherein, each of the bolt assemblies are sequentially directed into the rear track section; and (ii) a fire position wherein the bolt assemblies are directed into the front track section. The top cover assembly can include a solenoid for moving the selector switch between the safe position and the fire position in response to an electrical control signal.

IPC Classes  ?

• F41F 1/10 - Revolving-cannon guns, i.e. multibarrel guns with the barrels and their respective breeches mounted on a rotorBreech mechanisms therefor
• F41A 35/02 - Dust- or weather-protection caps or covers
• F41A 3/60 - Breech mechanisms for guns having two or more barrels
• F41A 9/36 - Feed mechanisms for revolving-cannon guns
• F41A 19/18 - Mechanical firing mechanisms for multibarrel guns

Abstract

An improved barrel clamp assembly for a multi-barreled minigun includes a barrel clamp tube having a front end, a rear end, and a plurality of longitudinal openings extending along a portion the length of the tube between the front end and the rear end. An impeller is mounted in the barrel clamp tube between the tube front end and the tube rear end. The impeller includes a plurality of impeller blades that are spaced around a periphery of the impeller and that project forward from a rear flange portion of the impeller and the impeller blades define a plurality of air channels. A barrel assembly includes the barrel clamp tube, a flash suppressor mounted to the front end of the barrel clamp tube, and a barrel clamp collar mounted to the rear end of the barrel clamp tube. The impeller is mounted to the barrel clamp tube between the flash suppressor and the barrel clamp collar.

Abstract

A delinking feeder of a minigun includes an access door mounted to a delinking feeder housing and movable between a closed position and an open position. The access door has an enclosed recess for receiving a tongue that is rotationally coupled to the access door and is movable between a retracted position and a deployed position. When the access door is in the open position, the tongue is in the deployed position and a tongue first contact surface can contact and secure a linked cartridge positioned in the delinking feeder. When the access door is in the closed position, the tongue is in the retracted position and a tongue second contact surface can contact and guide a cartridge positioned in the delinking feeder. The enclosed recess is covered so that when the access door is in the closed position, the tongue does not protrude through the access door.

Abstract

An improved delinking feeder receives a belt of linked cartridges, separates cartridges from the belt, and feeds the separated cartridges to a minigun for firing. The delinking feeder includes a feeder sprocket with a plurality of slots extending outward to an open end at an outer edge of the feeder sprocket body. Each of the slots is disposed along a curve. The curve decelerates a cartridge disposed in the slot as the cartridge moves outwardly in the slot. A feeder shaft is adapted to hold the feeder sprocket and a stripper. The shaft includes a section having a plurality of exterior splines, and the feeder sprocket includes an axial hole having a plurality of interior splines configured to mate with the plurality of shaft exterior splines. The stripper sleeve includes an axial hole having a plurality of interior splines configured to mate with the plurality of shaft exterior splines.
