Abstract
An ammunition feed system for a firearm that can pivot in elevation about a horizontal elevation axis includes an ammunition storage device, a loading device and an intermediate transfer section. The ammunition storage device is fixed relative to the elevation axis. The ammunition storage device includes at least two magazines with a common first entry/exit opening through which the rounds of the ammunition pass. Each of the two magazines has a round transport assembly. The rounds are unconnected and selectively movable in a loading direction from the two magazines through the first entry/exit opening and in an unloading direction opposite the moving direction. The loading device individually loads the rounds into a firing chamber of the firearm and moves with the firearm in elevation. The intermediate transfer section links and transfers the rounds between the ammunition storage device and the loading device. The intermediate transfer section includes a first two-way round transfer device linked with the ammunition storage device to guide the rounds through a second entry/exit opening. A second two-way transfer device guides the rounds between the second entry/exit opening and the loading device. A drive shaft drives the first and second two-way round transfer devices and at least the respective round transfer assembly of the selected magazine. A synchronization device maintains the nonselected other of the two magazines in synchronization with the intermediate transfer section during movement of the firearm in elevation.
