ABSTRACT:
A plurality of bar hooks are disposed in an array proximate the upper area of a file enclosure, and are each formed with a pair of oppositely extending arms. The arms, disposed for co-action with the ears forming the binary code on a plurality of edge coded files, are selectively actuateable to enable retrieval of selected ones of said files; even though the files have been returned to the enclosure in random order irrespective of any consecutive order of the numbering of said files. The enclosure carries one or more coding bars corresponding to a special edge code notched into the files to restrict return of the file to its proper enclosure. A latch bar extends along each side of the enclosure for co-operation with side notches provided in the files to support same out of contact with the arms of the bar hooks to facilitate actuation of the bar hooks for card retrieval. In some of the embodiments the bar hooks are supported by mounting plates which extend along the length of the bar hook. In other embodiments the bar hooks as well as the latch bars are moved into operative position by a cam plate that engages the bar hook and/or latch bar substantially along its length. The enclosure is further provided with a conveyor that carries the selected file to an outlet opening formed in the enclosure.
