A bulk material conveying apparatus consisting of an endless chain of elongated containers is disclosed. Each container has a closed end and an open end, with orientation of the containers alternating so that in a horizontal traveling position, open ends are adjacent and in sealing relationship. The ends of successive containers are pivoted together, and guide tracks and followers are provided at and near loading and unloading stations so that as the containers approach the station they are rotated from a horizontal end to end position to a vertical side by side stacked together position. In the station the containers move slowly for loading or unloading, then are rotated back to the horizontal position as they progress for high speed travel to the other station. While traveling between stations the containers are inverted so that their open ends are up at loading stations and down at unloading stations.
