ABSTRACT:
A skirt assembly and swinging gate are both pivotally mounted on a bin hopper. The gate carries a cam which engages a follower on the skirt assembly. When the gate is closed, a notch in the cam face lifts the follower arm and the skirting assembly to its most elevated position. The final lifting action occurs while the gate is over-travelling its effective closed position. When it is desired to open the gate, the cam action is reversed until the skirt reaches sealing position; further engagements of the skirt assembly on the belt is prevented by a stop on the skirt which engages the hopper and operates with the cam face to lock the skirt in the exact position desired. It is held in this position during subsequent gate opening and regardless of the degree to which the gate is opened.
