ABSTRACT:
A continuous bucket elevator used in a method of separating coal according to its size and for cleaning refuse material from the coal in a Baum-type jigging apparatus wherein each bucket is connected to the adjacent bucket by a link received by a roll pin held by a bushing at each end in each bucket and the flange of a plate which is centrally welded to the bucket and has portions biased outwardly therefrom which merge into further portions having openings for receiving the roll pins, the diameter of the aligned openings in the further part, in the bushings, and in intervening link and the diameter of the roll pins being such so as to restrict wear due to the abrasive nature of the material being handled so that all components of the elevator wear out at about the same time and need not be replaced until after two or three cycles of use, each cycle being normally for seven and ten months.
