  • Patent number: 3956109
    Abstract: An apparatus for sorting silverware including a hopper for collecting the silverware in bulk amounts and a vibrating bed for gradually discharging the silverwave and conveying it to a sorting stage for dividing the different types of silverware. The sorting stage includes a table defining a barrier against which the silverware is directed. Laterally extending openings are defined by the barrier, and these openings permit the passage of knives past the barrier means. Forks and spoons are held by the barrier means as they are moved over the table and are then dropped onto a structure which separates the forks and spoons. Receptacles are provided for collecting the different types of silverware.
