Abstract

Documents 10 are transported from a work station, not shown, by continuous belt 15. They are transferred to and brought into stacking position by perforated continuous belt 20. This is trained about longitudinally spaced rollers 21 and 22 so as to cover the mouth of vacuum chamber 25. Either a single perforated belt 20 and single vacuum chamber 25 or a series of laterally spaced belts 20 and chambers 25 can be used. Depending upon the construction, kick-down spring 30 is mounted on the outboard sides of chamber 25 or between chambers 25 if more than one is used. Spring 30 is pivotally mounted at one end. in its normal position, it is formed so that a straight portion extends at an angle from the pivot to intercept the document path.

Documents 10 are transported from a work station, not shown, by continuous belt 15. They are transferred to and brought into stacking position by perforated continuous belt 20. This is trained about longitudinally spaced rollers 21 and 22 so as to cover the mouth of vacuum chamber 25. Either a single perforated belt 20 and single vacuum chamber 25 or a series of laterally spaced belts 20 and chambers 25 can be used. Depending upon the construction, kick-down spring 30 is mounted on the outboard sides of chamber 25 or between chambers 25 if more than one is used. Spring 30 is pivotally mounted at one end. in its normal position, it is formed so that a straight portion extends at an angle from the pivot to intercept the document path. It extends and curves upwardly to again intercept the document path and be free at its other end. Spring 30 upon being engaged by a document is pivoted upwardly out of the document path so as to ride on the upper surface of the document. Spring 30 is located so as to be engaged by the leading edge of the document as it enters into the stacking area.

A deflector and hold-down spring 40 flanking chamber 25 is fixedly mounted at one end. It extends downwardly toward stacker platform or elevator 45 so that a curved portion rests upon elevator 45. This is when it is in its uppermost position or upon the top document residing on elevator 45. Spring 40 extends upwardly beyond the document path. Again, depending upon the impl...
