Abstract
Abstract A roller assembly is suspended from the top of a tray to deflect sheets transported along a predetermined path into a path tangential to a roller member at the bottom of the assembly. Hanging wire devices are positioned along the same plane at the upper portion of the roller assembly and pivot to compact the part of sheets being received to clean a path for the next incoming sheet and effect a neatly aligned stack.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
126 words
In sorting apparatus in which sheets are moved along a horizontal path and deflected downwardly into substantially vertical trays, an improved stacking control apparatus comprising: a roller assembly suspended from the inlet of an associated tray and extending substantially in a vertical direction along the length of the tray, including a frame member and roller means positioned at the lowermost portion of said frame member to receive the downwardly directed sheets, and a plurality of wire members pivotally supported on the same axis as said roller assembly extending from the top of said tray for guiding the sheets along a predetermined path in the direction of said roller means and impacting the top portion of the sheets to clear the path for the next incoming sheet.
Claim 2
Dependent Claim
126 words
