Method and apparatus for conveying materials

A conveyor system comprising,

• (a) a series of buckets supported by an entrainment means defining a predetermined endless path having straight portions and at least one internal curve;
• (b) an individual elongate pivoting arm supporting a respective bucket on the entrainment means, each said pivoting arm being attached to the entrainment means at a first end thereof in fixed orientation to said entrainment means, and pivotally supporting the bucket at an opposite, free, second end thereof;
• and
• (c) guidance means engaging said entrainment means in advance of said at least one internal curve in the endless path to cause the free, 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 said internal curve in the endless path of the entrainment means being transited and thereby space the buckets further apart prior to and while negotiating said internal curve in the endless path than when the buckets are proceeding along a straight portion of the endless path.
