Patent # 5226547

Date: July 13, 1993

Abstract: A mail transport assembly for a mail sorting system includes a plurality of sets of drive units mounted on a transport surface. Each of the sets includes at least one diverter pivotally mounted to two positions. An endless inner belt is rotationally mounted generally in line with the diverter in one of the positions of the diverter. A drive belt has a run in contact with the inner belt so as to convey items of mail in a downstream direction when the item is directed thereto by the diverter. An intermediate belt is located with a run in contact with the inner belt so that rotation of one of the belts causes the other belt to rotate. A side belt is in contact with the intermediate belt to drive mail directed by the diverter into a collecting bin.
