ABSTRACT:
A bulk-storage apparatus has a large hopper adapted to hold a large supply of bulk material and having a floor formed with a central outlet opening centered on a vertical axis and a side wall extending upward from the floor. An upwardly tapered hood generally centered on the axis and open downwardly toward the opening has a lower edge vertically spaced from the floor around the opening. A drive supported in the hood has a rotary output projecting down into the space between the floor and the lower edge above the opening and carries an arm sweepable over the floor around the opening by the drive. The hood is supported in the hopper on at least one tubular traverse having an inner end secured to and opening into the hood and an outer end secured to and opening outside the hopper. This traverse is of a cross-sectional size big enough that a man can crawl between outside the hopper and inside the hood along the traverse. An openable cover closes the traverse between its ends. Thus the drive in the hood is accessible through the tubular traverse so that a man crawl through the traverse into the hood to service the drive while the hopper is full.
