Sheet stacker with jogger

Claim 1

A sheet stacker with a jogger, for conveying, jogging, and stacking a stream of imbricated flexible sheets, comprising a horizontally disposed sheet conveyor for supporting said stream thereon in a horizontal orientation and including two support portions disposed adjacent each other along the path of said stream and being horizontally spaced apart and with the one of said portions which is downstream from the other of said portions being disposed at an elevation lower than the elevation of said other portion to have said portions present a gap therebetween for passing said stream across said gap and from one of said portions to the other of said portions and to thereby permit said stream of sheets to curve in its said path of flow and about a line extending across said stream and downwardly across said gap and thereby cause said sheets to stiffen in the directions parallel to said line, a plate pivotally disposed adjacent the side of said stream and extending adjacent the location of the bend in said stream and being movable into and out of contact with the edges of said stiffened sheets adjacent said plate for jogging said sheets into alignment with each other, a pivot mounting for said plate and disposed downstream from the location of said gap and relative to the stream movement of said sheets for greater pivotal movement of said plate at its extent adjacent said gap than at the pivot location on said plate, oscillating mechanism connected to said plate for inducing the pivoting of said plate, and a stacker platform disposed adjacent said conveyor and downstream from said plate for receiving the aligned said sheets when the latter move off said conveyor.
