Abstract
To distribute power to plural, widely spaced driven sprocket sets of an ammunition magazine chain conveyor, one or more elongated drive shafts, driven by a prime mover, are journalled in closely spaced relation to a magazine sidewall and carry worms in axial positions to mesh with worm gears fixed on the sprocket shafts of the driven sprocket sets. The axial positions of the worms on the drive shafts are conveniently adjustable to coordinate the timings of the driven sprocket sets. One of the driven sprocket sets is also positionally adjustable to tension adjust the ammunition chain conveyor.
