A compound disc is used to eliminate a secondary slot normally formed between adjacent shafts of a material separation screen. The compound disc includes a primary disc joined to an associated secondary disc. The primary disc and the secondary disc each have the same shape but the secondary disc has a smaller outside perimeter and is wider. The primary disc and associated secondary disc are formed from a unitary piece of rubber. The compound discs are interleaved with oppositely aligned compound discs on adjacent shafts. In other words, the large disc is positioned on a shaft to align with a smaller disc on an adjacent shaft. The oppositely aligned and alternating arrangement between the large discs and small discs reduce problems that exist in screens that use in-line multi-sided discs.

[ What is claimed is:] [1.] A material separation screen, comprising:a frame;a first shaft and a second shaft mounted adjacent to and substantially parallel with one another on the frame;a first compound disc mounted on the first shaft and a second compound disc mounted on the second shaft, each compound disc having a primary disc with a first outside perimeter, and a secondary disc abutted against a lateral side of the primary disc having a second outside perimeter smaller than the first outside perimeter;wherein the first and second compound discs are spaced apart from adjacent compound discs on their respective shafts; andwherein the first compound disc on the first shaft is aligned with the second compound disc on the second shaft such that they overlap to form a stair-shaped gap between them.
