Abstract
An on-edge stacker having a deck surface to support a vertical mail stack, which is allowed to expand from the upstream end to the downstream end. A paddle, movably mounted on a linear support member, is used to support the downstream end of the mail stack. The linear support member is positioned at a level lower than or substantially the same as the deck surface so that the mail can be swept from the deck surface from either longitudinal side of the stacker. A toggle switch is disposed near the downstream end so that when the paddle moved by the expanding stack reaches beyond a certain point, the toggle switch is triggered to indicate that the stack is full or almost full. The paddle has a wedge-shaped blade so that it can slide the stacked mailed on the deck surface without damaging the mail.
