Abstract
A double-gated pool hopper is disposed above a pair of single-gated weigh hoppers such that articles in the pool hopper can be selectably discharged into either of the weigh hoppers by opening and closing the corresponding one of the two gates of the pool hopper. A single stepping motor controls the selective opening and closing of the two gates of the pool hopper by rotating in one direction or the other and another single stepping motor controls the selective opening and closing of the gates of the pair of weigh hoppers by rotating in one direction or the other.
