13 METHOD AND APPARATUS FOR CONVEYING MATERIALS A conveyor system comprising a series of buckets supported by a chain along a predetermined endless path having straight portions and at least one internal curve. An individual pivoting arm supports a respective bucket on the chain. Each pivoting arm is pivotally attached to the entrainment means at a first end in fixed orientation to the chain, and pivotally supports the bucket at the opposite second end. A chain guide engages the chain in advance of an internal curve in the path to cause the second end of the pivoting arm to which the bucket is attached to pivot outwardly and the buckets in turn to follow a diverging curved path of greater radius than the radius of the curve in the path being transited and thereby space the buckets further apart prior to negotiating the internal curve in the path than when the buckets are proceeding along a straight portion of the path. |
