Abstract

The mechanism directs document cards 10, first into a stacker 1 or a stacker 2; and then, when one stacker is filled, it automatically directs cards 10 into the other stacker, assuming that the latter stacker has been made ready by the operator by turning switch 11 toward the stacker that is empty. By emptying one stacker and turning switch 11 toward the stacker just emptied, the operator can process all of the cards 10 without stopping the device.

Progressive Stacking Mechanism

The mechanism directs document cards 10, first into a stacker 1 or a stacker 2; and then, when one stacker is filled, it automatically directs cards 10 into the other stacker, assuming that the latter stacker has been made ready by the operator by turning switch 11 toward the stacker that is empty. By emptying one stacker and turning switch 11 toward the stacker just emptied, the operator can process all of the cards 10 without stopping the device.

The selector magnet 15 is energized by providing a nonprocessing run-out signal on lead 12 applied to OR circuit 13 which applies a set signal to flip-flop 14 whereby magnet 15 moves flipper 16 upwardly. Cards 10 then move into stacker 1 onto support 17. Cards 10 form a pile in stacker 1, moving support 17 downwardly against its spring 18; and when stacker 1 is filled, switch 19 is opened. Stacker 2 has a support 17a acted on by spring 18a and actuating switch 19a corresponding to parts 17, 18, and 19 in stacker 1. With stacker 19 being opened, if switch 11 has previously been moved to its stacker 2 ready position and cards 10 have been removed from stacker 2 to close switch 19a, AND circuit 20 has all of its inputs satisfied and provides a reset signal on flip-flop 14, thereby de-energizing magnet 15, allowing flipper 16 to drop. Thus, when stacker 1 fills causing switch 19 to open, flipper 16 directs cards 10 into stacker
2. Similarly, assuming the switch 11 has been moved to its stacke...
