Abstract
A cartridge feed mechanism of an automatic firearm is mounted pivotably on a drive housing. In the pivoted-up position, a coupling tongue 15 of the transmission shaft 9 of the cartridge feed mechanism engages with a coupling groove of a drive sleeve of the drive housing. The coupling tongue shall be prevented from rotating when the cartridge feed mechanism is pivoted down from the drive housing. For this purpose, a slide 16, which locks the transmission shaft 9 in a locking position and releases it in a releasing position, is mounted on the cartridge feed mechanism. Slide 16 is pressed by the drive housing into its releasing position when the cartridge feed mechanism is in the pivoted-up position. In the pivoted-down position of the cartridge feed mechanism, it is brought into its locking position by a compression spring.
