  • This invention relates to coders, and more particularly to coders which encode documents, such as cards, by selectively removing one or more teeth formed on the card edge.
  • the coder of this invention is described in connection with its use in a particular mechanized data retrieval system with which it possesses an unusually high degree of utility.
  • the coder of this invention is described in connection with the retrieval system disclosed and claimed in thecopending patent application of Robert D. Parry for Article Selection System," filed Aug. 4, I967, Ser. No. 66l,758 now U.S. Pat. No. 3,478,877.
  • a plurality of rectangular cards are provided on which data may be stored in the form of printed informatlonymicrofilm or the like.
  • Each card includes a plurality of sawtooth or ramp-shaped teeth formed along one edge of the card, preferably the lower edge.
  • the cards are encoded by selectively removing, or notching, one or more of the teeth located along the card edge.
  • the cards once encoded are randomly stored in a unique card selecting apparatus in face-to-face relation with their encoded tooth-bearing edges lowermost. With the cards so stored, the encoded edges are operatively associated with a plurality of transverse card sorting bars which form part of the selecting apparatus. The sorting bars cooperate with the card teeth, permitting all cards to be simultaneously searched and oneor more desired cards having a predetermined removed tooth pattern to be physically separated from the remaining undesired cards-not having the predetermined removed tooth pattern.
  • a number of criteria must be satisfied if the coder is to be commercially feasible.
  • the coder must be made as inexpensively as possible consistent with reliable operation.
  • the punch and die assemblies of the coder which in actuality perform the tooth notching, should be susceptive of easy and inexpensive replacement when they become dull.
  • the coder should have simply constructed and easily operated means for properly locating and positively gripping a card when inserted into the coder.
  • This objective has been accomplished in accordance with certain principles of this invention by providing a coder which includes the very novel and unobvious combination of an elongated card edge support block having therein a slot configured to receive and guide thetooth-bearing edge of a card to be notched, and a plurality of notching assemblies removably located in suitably provided bores in the guide block which communicate withthe card edge guide slot.

  • An advantage of a coder incorporating the foregoing concept is that the notching assemblies can be easily replaced when they become dull. It is only necessary to remove the dull punch and die from its associated bore in the card guide block, and insert a new one.
  • a further advantage of the coder of this invention, particularly the novel and unobvious punch and' die, is that the punch is always assured of alignment with the die.

  • the cutting surface of the punch is oriented such that it makes angles of approximately and with respect to imaginary vertical and horizontal planes passing through the axis of a horizontally disposed punch. It has been discovered that with a punch cutting surface so angled, the power required to selectively notch a card tooth is only approximately one-third as much as that required when the punch assumes other angular orientations such as when rotated 90 from the preferred angulation.
  • This objective has been accomplished in accordance with certain additional principles of this invention by providing, in combination with a pair of parallel plates spaced to define a card insertion slot, a third plate movably mounted between the pair of slot-defining plates.

  • Removal of a tooth T properly registered in the cross-slot 93 is effected by moving the punch 87 axially within the bore 82 from the solid line position shown in FIG. 6 to the dotted line position. Movement of the punch 87 in this manner shears the tooth T from the bottom edge 23c of the card 23 along the arcuate base line 97.

  • the transverse slot 93 which in combination with the punch 87 acts as a die, is formed in the bushing 80, and because the bushing slidably receives the punch 87 within its bore 82, the punch 87 is always in proper alignment with the die cross-slot.
