Abstract
A two-barreled machine gun has two fixed firing chambers, a conveyor, and a feed system mounted within a housing. The feed system transfers ammunition from the conveyor to the firing chamber. The feed system includes a sprocket barrel pivotably mounted about its central longitudinal axis. The sprocket barrel has two receptacle slots and two discharge slots circumferentially spaced thereabout. The sprocket barrel is rotatable between a first and second position. The receptacle slots each have a first position aligned with the conveyor to receive a round of ammunition and a second position aligned with a respective firing chamber. One receptacle slot is in its first position when the other is in its second position. The discharge slots also have a first position aligned with the firing chambers and a second position aligned with an outlet in the housing. One discharge slot is in its first position when the other is in its second position. An ejector cam is also rotatably mounted along an axis aligned with the axis of rotation of the sprocket. The ejector cam is fitted within a central hollow of the sprocket barrel. A drive gear connected to the sprocket barrel oscillates the sprocket barrel between its first and second positions and a second drive gear oscillates the ejector cam so that it laterally passes through the first and second discharge slots when in their respective second positions. The ejector cam ejects any cartridges from the discharge slot as it passes therethrough.
