Abstract
An improved hopper and conveyance tube combination which is resistant to clogging and more easily loaded. Material is delivered from the hopper and into the conveyance tube through an inlet opening in the side of the conveyance tube. Because the inlet opening is in the side of the conveyance tube, the tube can not become completely clogged. Air or conveying fluid is always able to move through the conveyance tube and eventually conveys all of the materials to the desired destination. A ramp connected to the rim of the hopper permits materials on the floor to be easily swept up the ramp and into the hopper.
