Sheet jogger

In combination with a sheet receiver including a vertical column of sheet receiving compartments, jogging means including side jogging means mounted adjacent one side of the receiver and movable with respect to a side jogging position in simultaneous contact with the side edges of stacked sheets in said compartments for establishing coplanar alignment thereof, and side backup means mounted adjacent the opposite side of the receiver and engagable with the opposite side edges of the stacked sheets in said compartments for establishing coplanar edge alignment thereof simultaneously with operation of said side jogging means, the improvement comprising:

• end jogging means mounted adjacent one end of the receiver and movable between a retracted position spaced from the end edges of the stacked sheets in said compartments and an advanced jogging position in simultaneous contact with the end edges of the stacked sheets in said compartments for establishing coplanar alignment thereof;
• backup means mounted adjacent the opposite end of the receiver and engagable with the opposite end edges of the stacked sheets in said compartments for establishing coplanar alignment thereof simultaneously with operation of said end jogging means;
• and
• sheet stop means mounted by the receiver adjacent said end jogging means at a location intervening between said retracted position and said advanced jogging position for engaging the end edges of sheets entering said compartments from the opposite end of the receiver toward the one end thereof, and positioning the sheets upon such entry thereof into said compartments with their end edges spaced from said advanced position a sufficient distance that said end jogging means may thereafter contact the sheet end edges and move the sheets against said backup means into coplanar end edge alignment.
