Abstract
A discharge chute assembly (30) includes a chute (32) and a pivotal deflector (34), the overlapping end portions of which define a partial spherical or ball joint (40) which maintains a tight seal against backflow and leakage over the entire range of rotation and deflection of the assembly. The assembly (30) is preferably secured to a rotatable base (54) by means of lower pivots (70) and a releasable fastener (72) for collapsibility.
