ABSTRACT:
A reversible arrangement for transporting bulk materials includes a plurality of buckets mounted on a bucket wheel for rotation therewith and for pivoting between respective end positions in which the open ends of the buckets face in respective circumferential directions of the bucket wheel. The buckets are mounted on levers which are interconnected by flexible elements for coordinated displacement of the buckets between the end positions. The bucket wheel carries two circumferentially and radially spaced cams which control the extent of displacement of cam followers of respective switches between their respective retracted and extended positions. A detaining arrangement is situated along the path of movement of the buckets and engages one of the buckets during the reverse motion of the bucket wheel to detain the bucket while the bucket wheel continues to rotate so that the buckets are angularly displaced between their end positions. One of the above-mentioned switches controls the detaining arrangement, while the other switch prevents actuation of the one switch when both of the cam followers are aligned with their associated cams. The arrangement includes further switches arranged in a control circuit with the aforementioned switches and accomplishing therewith an automatic reversal of the operation of the arrangement.
