ABSTRACT:
A hopper with two sets of parallel sides and a bottom, connected at ninety degree angles forms a rectangular shell. An opening in one of the sides, remote from the bottom, forms a dispensing port. An internal liner is connected, at one of its ends to the side in which the opening is located, at a location just below the opening. The liner extends down the one side, across the bottom and up the side opposite the one side. The liner supports bulk material stored in the hopper. A liner take-up mechanism is positioned over the side opposite the side in which the dispensing port is mounted. The liner is secured to the liner take-up mechanism. The liner take-up mechanism is operated to reduce the length of the liner positioned in the rectangular shell, thereby lifting the bulk material supported by the liner.
