1. A dual feed device for weapon with external motor and rectilinearly shifting breech, wherein the device includes firstly a round positioning device including one of central positioning sprocket (7) unit (6), and secondly two feed casings (1, 2) loaded with various ammunition, placed on either side of the central positioning spocket unit and linked together by a common support (3), with both said cases being capable of tilting around axes (4, 4') parallel to the lengthwise axes, and each having means of coupling with and uncoupling from the positioning device, wherein the feed units each includes one feed unit (5, 5') sprocket (8, 8'), their means for coupling with and uncoupling from the positioning device consisting of claw couplings (13, 13') for coupling each of the feeds sprocket units to a reducing transmission (9), with one feed sprocket unit being coupled simultaneously with the decoupling of the other when one casing tilts, wherein the dual feed further has means (21 to 25) for reversing the direction of rotation of the central positioning sprocket whenever one of the casings tilts. |
