Definitions

  • the present invention relates to sorting ma chines and more particularly to sorting machines in which perforated record cards are fed singly from a magazine and distributed to selected pockets in accordance with the location of perforations in the card columns.
  • the principal object of the invention is to provide checking devices for checking the sequence of 9, series of record cards according to data perforations in one column thereof, while the cards are being sorted in accordance with data perforations in another column thereof.
  • a further object of the invention is to provide improved devices for checking the occurrence of erroneous data perforations in a card column during sorting operations.
  • Fig. l is a View, partially in section, of the card feeding and distributing mechanism of a well known type of sorting machine.
  • Fig. 2 is a view looking in the direction of lines 2-2 of Fig. 1.
  • Figs. 3 and 3a placed one above the other constitute a wiring diagram of the machine.
  • Fig. 4 is a timing diagram of certain of the electrical devices.
  • the sorter includes a supply magazine It (Fig. 1), a card picker l I for feeding the cards one at a time through a throat l2, and means comprising a linkage 53 operating from a main As arecord on a screw 19.
  • the pitch'of screw 19 is such" 1 Claim. (Cl. 209-110) one revolution of a handle 2t at its end will shift brushes HS, ll'C one column space in either direction.
  • the screw is mounted for vertical reciprocation and carries cams 2i at its extremities which cooperate with stationaryrollers 22,-so that at the beginning of the rotation of screw it it-will be cammed upwardly to lift the brushes offcontact roller it, and near the end of the revolution of the shaft the brushes will descend again.
  • a pair of contacts 23 (Fig. l) are provided and arranged with the upper blade thereof extending over the hub of handle 26.
  • a magnet 26 is energized attracting its armature 27. If, when armature 2'! drops, the card has passed under some of the blades, the card will continue to hold these blades in their upper position. The other blades will drop with the armature z'i and the card will then move in the path formed by the first of the lowered blades which will guide the card to the pocket corresponding to the position of the hole in the card.
  • Located in the path of the cards are the socalled card levers 28 and 29 which are actuated by the passing cards to close contacts CL! GL2 and CL2a as diagrammatically represented in Fig. 3a.
  • the usual distributing commutator generally designated 39 (Fig. 3a.) is suitably geared to main shaft i i to make one revolution for each card cycle and the relative timing of its related wipers Di, D2 and D3 is as shown in the time chart (Fig. l), wherein are also shown the times in the cycle when the hole positions in the cards are at brushes its and ETC. 7
  • card lever contacts CLi close near the end thereof and in the next cycle contacts (3L2 and CLZa close near the middel of the cycle.
  • These levers are constructed as usual so that, when closed, they remain so as long as cards continue to follow in succession, since the leading card does not leave the lever until the following card has engaged it.
  • a pair of timing contactors designated TI and T2 (Fig. 3) are provided and each comprises a ring of stationary contact segments 3
  • Sorting brush HS is shifted to traverse the tens column 51 and brush HC will traverse units column 52.
  • the cards are now resorted according to the tens order digits, and during this sort brush [1C will through circuits to he explained ascertain whether the units or digits follow in ascending sequence and, if a card is out of sequence, the machine will stop. Such possible misarrangement may be due to carelessness on Pocket 9 8 7 6 5 4 3 2 1 0
  • the operator now again removes the cards from the several pockets and replaces them in the magazine II] in ascending order of their tens values as follows;
  • Sorting brush Us is shifted to traverse the hundreds column 50 and brush "C will traverse tens column 5
  • the cards are resorted according to the hundreds order as follows:
  • the cards may be placed in the magazine, brush I'IS shifted to traverse a blank column 49 with brush I'IC traversing the hundreds column 50. As a result, all the cards will feed into the reject pocket while brush 11C checks for correctness of sequence.
  • Key contacts 33 are held closed until a card has advanced sufficiently to close card lever contacts 0L2, CL2a when a holding circuit will be established from side of line, relays R3I, and R32, relay R30, its contacts R30A, stop key contacts 35, wire 31 (Fig. 3), contacts R20AL of a relay R29 (normally closed) wire 33 (Fig. 3a), pocket contacts 36 (which open if a pocket becomes full), contacts CL2a to side of line. As long as cards continue to feed, this circuit will be maintained.
  • magnet 26 is energized in each of the succeeding cycles to select the appropriate pocket, so that the cards are distributed in the order set forth hereinabove.
  • Brush ⁇ 1C is, of course, inefiective as it rides on a blank column. If, however, such column 53 contained perforations (relating to other data), switch 44 (Fig. 3) is set in its open position for the first sorting run to interrupt any circuit through brush ITO. When the last card has passed the card levers, their contacts open and the machine stops automatically.
  • the units column of the first card contains a perforation and, as this passes brush ITC, a circuit is partially completed from side of line (Fig. 3a), contacts CLi, distributor wiper DI, 0 contact segment 39, wiper D2, wire Mi (Fig. 3), contact roller l6, 0 hole in column 52, brush IIC, switch 44 (now closed), wiper 32 of timer TI, 0 segment 3!, 0 wire 45 to contacts RIBL where the circuit is open.
  • 0 is the first digit sensed in a run
  • no circuit is completed.
  • the next two cards sensed also have 0 holes in column 52 and these likewise are sorted by brush NS.
  • the fourth card has a 2 hole which will complete a circuit as before to roller l6 (Fig. 3), thence through the 2 hole, brush IIC, switch 44, brush 32 of timer TI, 2 segment 3!, 2 wire 5, a winding of relay R2, wire 46, resistor 41, wire 48 (Fig. 3a), reset key contacts 49, contacts 23 to side of line.
  • Relay R2 closes its contacts RZAL to set up a holding circuit traceable back from side of line through wires 48, 46, contacts RZAL, second winding of relay R2, wire 55] (Fig. 3a), card lever contacts CLI to side of line, so that relay R2 will remain energized throughout the remainder of the run.
  • Relay R2 closes its contacts RZBU which concurrently complete a circuit between Wire db and a winding of relay RI and wire t, so that both relays RE and R2 are held energized.
  • relay R3 which, if there had been no prior 2 or 1 hole cards, would through ans-see 6 its contacts R3BU energize relay R2 and the latter through its contacts RZBU would energize relay RI. 1
  • any relay R2 to R9 when any relay R2 to R9 becomes energized, it will cause energization of all lower valued relays in the chain RI to R9. If all cards are in proper sequence, such setting of the relays is ineifective and their holding circuit will open when the cards run out and card lever contacts CLI open. Opening of contacts 23 upon the next brush shift also breaks another point in the holding circuit.
  • relay R20 will be energized whenever a lower value digit is sensed by brush iiC after sensing of a higher valued digit.
  • the device makes a further check during the run to detect any erroneous double punching in the card column as where, for example, through some inadvertence an operator punches a 3 and a 1 hole in a column when only the 3 hole should appear.
  • the 3 hole would pick up relays R3, R2 and RI and later in the same cycle the circuit through the 1 hole would pick up relay R20 in the same manner as though the 1 hole had been in a following card.
  • relay R20 is energized whenever a hole sensed has a lower value than a hole sensed in a prior cycle or sensed in the same cycle for the same card column.
  • Relay R20 when energized closes its contacts RZUBU to establish a holding circuit traceable in part from wire 59, the second winding of the relay, contacts RZOBU to wire 48 so that it will remain energized until cards run out.
  • Timer T2 (Fig. 3) has its wiper 32 connected to brush US through a switch 54, so that each sorting circuit will branch from brush ITS, through switch 55, wiper 32 of timer T2, appropriate segment 3! and wire 55 to a magnet prefixed M as Md, Mi, etc. to M9, thence through common wire 5% to cam contacts CI (timed to close during the sensing of the digital positions on the card, Fig. 4), and wire 51 (Fig. 3a) to side of line.
  • Contacts MBA for example, close a holding circuit from side of line, wire 51, contacts CI, wire 56, con- 7 tacts MOA, winding of relay M0, wire 50, to side of line, through card lever contacts CLI.
  • contacts Cl open between card cycles, the M relay is deenergized.
  • switches 54 and 44 By opening switches 54 and 44 (Fig. 3), the machine may be employed for customary sorting operations without the checking features of the invention.
  • a sorting machine having a pair of adjacent sensing elements, means for feeding a succession of record cards past said elements, whereby each card is sensed simultaneously by both sensing elements, said cards each having a pair of columns in which data are represented by designations differentially located therein, and said pair of sensing elements each traverse one of said card columns, sorting mechanism controlled by one of said elements as each card passes the said one element for sorting the cards in accordance with the location of the designation in the related column of the passing card, checking mechanism controlled solely by the other of said elements as each card passes said other element for ascertaining whether the data therein has a predetermined sequential relationship with data in the same column of a preceding card, and means controlled thereby upon detection of a variance in said relationship for preventing further operation of said sorting mechanism.
