Two bucket, automatic grain weighing and delivering machine.
The following notes describing the machines and how they operated were provided by the inventor:
Comprises equal armed beam. Bucket at either end. The operations and weighments are governed by a ball (weight) running in a tube or channel which is connected to beam. The feed control gate is opened by beam when beam descends sufficiently. Gate is caught on a catch when the full weight is in bucket, beam descends further and knocks out catch allowing feed gate to close. The ball then runs to other end of beam and knocks up bucket door catch.
