Definitions

  • This invention relates to card controlled machines in general and more particularly to machines adapted to sort record cards such as are used to control the operation of the well known Hollerith type of tabulating machine.
  • the invention is shown applied to a sorting machine of the type disclosed in U. S. Patent No. 1,741,985, issued Dec. 31, 1929 to E. A. Ford.
  • a sorter in operation, feeds cards one-by-one by means of a picker knife Ill, from the bottom of a card stack II to rollers I2 which, in turn, feed the cards between a series of brushes I3 and a contact roller I4 in a well known manner.
  • the index or value perforations in the well known Hollerith card are differentially located from the leading edge of the card. After this edge of the card passes the brushes I3 it passes between a table I5, forming an armature for a pair of sorting magnets I6, and a series of guide tongues I1 pressed lightly into contact with said table by the inherent spring tension of the tongues.
  • the instant invention to sort the cards into two pockets, those cards having a single hole in a column being sorted into the 12 pocket I8 and those cards having more ,5 than one hole in a column being sorted into the reject pocket I9. This is accomplished by delaying energization of the sorting magnets I6 until the 12th index position on'the card reaches the brushes I3 thus directing the single hole cards into the 12th pocket, and by preventing energization of the sorting magnets I6 when two holes occur in a column, thus passing the card under all of the tongues and into the reject pocket I9.
  • Energization of magnet 30 closes its contacts 38 and sets up a circuit from the commutator 34, contacts 38, wire 39, switches 4
  • This circuit is not effective at this time to energize the sorter magnets since it is shunted across these magnets by a commutator 45, wire 46 and a switch 41.
  • the commutator is timed to open the shunt circuit as the 12th position on the card passes the brushes I3, consequently, if another hole has not been encountered, the sorter magnets will be energized at the 12th position, 4 thus directing the advancing card into the 12 pocket I8.
  • the machine may be driven by the usual electric motor M which is energized from the main lines 20-2
  • the machine will stop automatically when the lastwcard has passed the card lever 64 opening the card lever contacts 6
  • the machine may also be stopped at will by operation of the stop key 65 opening the contacts 63 to deenergize the motor relay magnets 56 and 55. 7
  • the machine may be made to function. in a normal manner, sorting into all twelve'pockets and the reject pocket under control of a brush 66 analyzing a single card column.
  • Switch 3 I magnet 36, switches 29 and 42, resistance 43,,line 44, s orter magnets l6 to the line 2
  • a sorting machine having a plurality of pockets, the combination of a plurality of sensing means to sense perforations in one or a plurality of columns on a record card in motion, card sorting means, electrical circuits conditioned by the sensing means when sensing a single column to control the sorting means to sort the cards into all of the pockets according to the differential location of the perforation in the column, an electrical switch to change the control of the sorting means from the single sensing means to the plural sensing means, a shunt circuit to control the sort-.
  • ing means to sort all cards having a single perforate index point in any one of a plurality of columns into a certain pocket, and a second shunt circuit conditioned by the first perforate index point to control the sorting means to sort the cards having plural perforate points in anyone column into another pocket.
  • sensing means to sense a plurality of columns on a' record card
  • sorting magnets to select the pockets
  • a commutator acircuit controlled by said commutator to delay energization of the magnets until a predetermined time
  • a circuitcontrolled by .a second perforation to prevent energization of thesorting magnets at said predetermined'time.
  • apluralityof sensing means to sense a plurality of columnsin perforated record cards, a sorting'magnet to select the pockets to receive the cards,; a circuit to energize the magnet when the sensing means encounters a perforation, a commutator, a shunt circuit controlled by the commutator to prevent energization of the sorting magnet until a predetermined time, and another shunt circuit controlled by a second perforation in any column to prevent energization of the sorting magnet at said predetermined time.
  • a sorting machine having a plurality of pockets
