ABSTRACT:
A bucket for attachment to the chain in a mill duty bucket elevator, includes a one piece wrapper member bent into a U-shaped trough defined by a sloping front wall, a horizontal bottom wall, an upright rear wall, a forwardly sloping rear wall, and a horizontal top lip. A rectangular hole in the wrapper plate defines the outside edges of a chain channel in which the chain lies when the bucket is fastened to the chain. Four side pieces having identical shapes and outside dimensions lie transversely across the trough to provide two end walls and two inside partitions. The partitions brace the front wall and act as side walls of the chain channel. A back plate fastened to the partitions and to the top lip and bottom wall adjacent the rectangular hole acts as the front face of the chain channel. The top lip, fastened to the two end walls and the two partitions, provides torsional stiffness to the bucket.
