Abstract

Cards 10 are selectively fed as feed roll 15 is first moved laterally into feeding position and then downwardly to engage the top card. This arrangement permits feed roll 15 to be recessed and thus provides the machine operator with an unobstructed view of the top card.

Dual Motion Feed Roll

Cards 10 are selectively fed as feed roll 15 is first moved laterally into feeding position and then downwardly to engage the top card. This arrangement permits feed roll 15 to be recessed and thus provides the machine operator with an unobstructed view of the top card.

Feed roll shaft 16 is selectively moved laterally by armature 19 when magnet 18 is energized. Shaft 16, rotated via pulley 20, moves downwardly as yoke 21 pivots clockwise in response to the combined action of interposer 22 and rotating cam 23. The latter slides with shaft 16 relative to pulley 20. Spring 24 seated within pulley 20 presses against cam 23 to hold the end of shaft 16 in contact with armature 19. Interposer 22 is spring-loaded and free to pivot clockwise relative to frame 25.

If cam 23 is at its high point as it moves axially, interposer 22 gives way and springs back into position at the next cam low point. Yoke 21 is held in a normal position by spring 26 which urges upstop 27 against bridge 28 of frame 25. The controls for energizing and de-energizing magnet 18 are not shown. However, magnet 18 is de-energized prior to a card moving out from under feed roll 15. This prevents card jamming.
