Definitions

  • Th s invention relates to apparatus of the kind comprising the combination of (a) a machine which, for sorting -statistical records, has a card reading device, a plurality of card receptacles and sorting mechanism operable under the control of the card-reading device to distribute the cards to the receptacles in accordance with the position of a hole or holes in a selected column on the cards, and (b) counting apparatus which has a plurality of units-counters each operated under the control ofthe said card-reading device to count the number of cards having, in a selected column or columns, a hole in a particular position or positions allocated to that counter.
  • the cards feed at the rate of 400 cards per minute and the capacity of the receptacles is 800 cards.
  • the sorting mechanism is disconnected from the card-reading device and the cards are delivered to a reject receptacle.
  • This receptacle will therefore become full after two minutes running so that the apparatus must be stopped, the receptacle emptied and the apparatus restarted, thus the capacity of the apparatus is Y., a coris. me, am No. mm
  • apparatus of the kind described above is provided with a plurality of change-over devices each associated with a separate one of a series of the card receptacles of the sorting machine and each so arranged as to be actuated as the result of the associated receptacle becoming fully loaded, and automatic mechanism operable by the actuation of one of the change-over devices to cause the sorting mechanism to pass the cards to the next receptacle in the series.
  • change-over devices each associated with a separate one of a series of the card receptacles of the sorting machine and each so arranged as to be actuated as the result of the associated receptacle becoming fully loaded
  • the automatic mechanism preferablyincludes a plurality of normally ineifective impulse-transmitting devices each associated with a separate card receptacle in the series and each so arranged as to be rendered effective by the actuation of the change-over device associated with the preceding receptacle in the series, to transmit an impulse to the sorting mechanism at such a time in each card cycle as will result in the sorting mechanism delivering the cards to the receptacle associated with the said impulse-transmitting device.
  • the automatic mechanism is conveniently constituted by a commutator having a conducting segment associated with each receptacle and a brush which is connected to said magnet and is operated in synchronism with the card feed to make contact with the commutator segments in succession at the proper times in the card cycle, and the change-over devices each includes a normally open pair of contacts closed when the device is actuated and connected in series with the commutator segment associated with the succeeding receptacles in the series.

  • the worm l 2 meshes with a worm wheel i2 on a shaft I4 which, through suitable mechanism, drives a picker I5 ( Figure 2).
  • the picker advances one card at a time to pairs 0! feed rolls it which feed the cards along the machine over sorting pockets l1.

  • the magnet 22 thus energized advances its counter one unit space. Simultaneously a circuit'is established through a magnet 22 which attracts its armature 42 and unlatches the contacts 28 which then open so that only one of the magnets 22 can be energized during one card cycle.

  • the apparatus may be used to count the cards in accordance with the holes in one column and to sort them in accordshoe with the holes in another column. It can also be used to sort the cards only, the counting machine being put out of action by disconnecting the plug connection 22 or removing the Brush I2. Further it can be used for counting the cards without sorting them it the switch 21 is moved to the full line position oi Figure 5 to disconnect the sorting mechantsm-from the brush It. When the sorting mechanism is out of action the cards pass in unchanged order into the pocket marked R. in j'igure 1.
  • the machine is started by depressing start key contacts 54 thus providing a circuit through stop key contacts 55, a relay magnet 56 and twomotor control magnets 51 and 59.
  • the relay magnet 59 then closes its contacts 58a to provide a holding circuit through the contacts 52a, all the contacts 52 in series and card lever contacts 59, the relay contacts 59a, the relay 59, and the motor control magnets.
  • the motor control magnets close their relay contacts 51a and 59a so as'to provide a circuit through the motor ill. If the machine is sorting the cards a switch 69 will be in dotted line position so that the opening of any of the contacts 52, 52a or of the card lever contacts 59 will break the circuit for the motor control magnets which will in turn interrupt the motor circuit.
  • the machine will stop as soon as the cards cease to feed or one of the card-pockets i1 becomes full and opens its associated contacts 52.
  • the switch 69 which is interconnected with the switch 21 for joint actuation will be adjusted to the full line position. The machine will then continue in operation until either the contacts 59 open owing to the cards failingto feed or until the contacts 52a are opened as the result of the extreme lefthand pocket I1 becoming full.
  • the twelve pairs of contacts 59 are connected on one side in parallel to the line 92. Each of these contacts is also connected to a separate conducting segment 6l of a commutator 92 which is driven from the shaft ll of the sorting machine.
  • a conducting ring 69 of the commutator is connected by a line 95 to the switch 21.
  • a movable brush 64 connects each segment M to the conducting ring in turn concurrently with the passage of a hole position under the brush.
  • the brush 94 rotates counter clockwise in Figure 5 and will make contact with the segment labelled 9 at the 9 time in the cycle, the segment labelled 9 at the 8 time cycle and so on.
  • the pair of contacts 59 connected to the 9 segment is the pair associated with the pocket I! labelled 8; the pair of contacts connected to the 9 segment are associated with the I pocket and so on, the pair of contacts connected.
  • the operation of the apparatus when the switches 99 and 21 are in the full line position and counting without sorting is proceeding as follows.
  • the operation of'the machine proceeds'until the pocket marked R becomes full and the associated contacts 59 are closed. :
  • the brush 64 sweeps over the segments until it reaches the llfsegment at which time the i2 hole position of the card is beneath the reading brush.
  • a circuit is then established through the contact roll 9
  • the sorting magnet 29 is thus energized at the 12 time in the card cycle and rocks its armature 29 so as to cause the card to pass between a pair of blades which will lead it to the I! pocket.
  • the action of the sorting mechanism is as previously explained, except that the magnet 29 is now energized at the proper. time by the com mutator 92 instead of by the reading brush l9.
  • the same circuit is established during the succeeding card cycles until the i2 pocket becomes full.
  • the pair of contacts 59 connected to the li segment of the commutator will then be closed and the commutator will establish the circuit for the sorting magnet 29 when it makes contact with the II segment, that is at the 11 time in the cycle.
  • the sorting magnet will be energized at the 11 time in each cycle and the cards will pass into the ii pocket.
  • the pairs of contacts 59 become closed successively as the sorting pockets fill up until finally the pair associated with the sorting pocket marked9 are closed and the 9 spot on the commutator becomes alive.
  • the cards will then be passed into the extreme leithand sorting pocket (as shown in Figure 1) until this pocket becomes full when the contacts 52a will be opened and the holding circuit for the motor control magnets 51 and 59 will be interrupted. The motor .will then come to rest.
  • the apparatus will continue in operation, when adjusted for counting only, until all 13 sorting pockets havebeen filled. Thus instead of the machine being stopped every two minutes it will continue in operation for 26 minutes andthe operator's time will not be wasted in constantly emptying the sorting pockets. Further the order of cards is unchanged. It will be apparent that the machine may be adjusted to continue in operation until any desired number of the 13 pockets have become full. Thus, if it is wished to stop the machine after the pocket labelled 2 has become full the switch 99 would be connected across the contacts 52 for the 5 righthand pockets only so that the pair of contacts 52 for the pocket marked 2 will be in series with the switch. The machine will then stop as soon as this particular pair of contacts opens.
