ABSTRACT:
A dust seal between a rotatable shaft and a passageway through a bin wall. A split sleeve surrounds the shaft and each section thereof carries a laterally extending plate section. Adjacent edges of the plate sections abut and are secured to each other to provide a composite plate which covers the passageway and overlies the adjacent portion of the bin wall. Threaded members carried by the bin wall extend through elongated slots in the plate sections with each slot being of a width and length greater than the diameter of the threaded member to permit adjustment of the plate sections relative to the bin wall.
