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.

A hopper gate operating assembly for an automatic weighing apparatus, said assembly comprising, a motor having a shaft, an elongated member securely attached to said shaft and extending perpendicularly therefrom, a first linkage system and a second linkage system each attached to a hopper gate at one end and having a contact part formed at the other end such that said gate is opened if said contact part is pushed and displaced, and a contact, piece attached to said elongated member distal from said shaft so as to move along a circular path if said shaft is rotated, said contact piece being disposed proximal to said contact part of at least one of said linkage systems such that said contact piece pushes and displaces said one proximal contact part if said shaft is rotated in a specified direction.
