Abstract

Stepped pusher slide 1 operates in the base of a punched card stacker of the radial type to move cards introduced from the right into vertical stack 3. Slide 1 reciprocates through distance D and lies between a pair of stationary stepped shoulder members 2, only one of which is shown. The forward edges of slide steps 4 and 5 are cut back so that they do not extend beyond the forward edges 6 and 7 of the corresponding shoulder steps. Because of this, the last several cards 8 and 9 introduced into the stacker are not pushed all the way down the steps. Instead, cards 8 and 9 remain in an inclined position with their bottom edges resting on the members 2 with their top edges bearing against the back surface of stack 3. This prevents card jams by keeping the last few cards in stack 3 from toppling over backwards onto the slide.
