ABSTRACT:
In a bulk material handling apparatus, a pair of fluid impervious flexible endless belts are arranged about drive and idler pulleys to provide a material receiving run of one belt, a substantially vertical elevator or lift run or elevating section where the belts are in face-to-face contact for receiving the material therebetween; and an upper material delivery run where the material is discharged at a different level. In the elevating section, fluid pressure means are provided to effectively cause engagement of the edge portions of the belts with one another in order to eliminate spillage of the material being elevated and also in the elevating section fluid pressure means are provided to urge the remainder of the belts toward one another. These means involve the use of fluid pressure in various ways.
