Definitions

  • This invention relates to machines especially adapted for sorting record cards in tabulating systems which use the Peirce combinational hole system of index point perforations, as distinguished from cards of the Hollerith type which use a single hole differentially positioned in the card column.
  • the reading position is a particular zone on a card and the holes are variously arranged in that zone instead of being positioned anywhere in a card columnextending from top to bottom of the card, as in Hollerith.
  • My invention is an improvement on the machine described in-detail in copending application by E. A. Ford, Serial No. 7 48,347 whichdiscloses a sorter of the horizontal type designed to sort Hollerith cards electrically and deposit each class in its proper station.
  • Fig. 1 is the front elevation of a sorting machine to which my device is adapted.
  • Fig. 2 is a section through the feeding mechanism, showing also some conveyor rollers, and the analyzing or sensing devices for the first two stations.
  • Fig. 3 is an extension of Fig. 2 to the left showing additional rollers and control devices.
  • a shelf or subthe motor 33 which drives the machine om pulley 34 by belt 35 to pulley 36 fast on shaft 37, which runs the full length of the machine in the rear, pulle 36 being on one end of it and handwhee 38 onthe other.
  • a stack of cards to'be sorted is placed in the feed magazine, as at 55, the operator adjusts his analyzin brushes and when the motor is started t e picker drum feeds the cards, one by one, from the bottom of the stack to the conveyor rolls, which carry them along horizontally above the receiving stations until each card is deflected downwards into one of the eleven receiving stations.
  • the feed mechanism consists of the rotary picker drum 61 driven from shaft 37.
  • Drum 61 carries in its rim a number of'picker blades 69 extending lengthwise of the drum ano. projecting therefrom a distance slightly less than the thickness of a card.
  • each blade in turn picks a card from the bottom of the stack and feeds it through the micrometer opening 72 provided between the bottom of fixed plate 73 and rollers 74, into the control of the conveyor'rolls.
  • the upper conveyor rolls are designated 82, there being two of them fast on shaft 83, while directly under each of these upper rollers is alower roll 84 fast on shaft 85.
  • the rolls are driven by worm 86 on shaft 37 through spiral gears 87 fast on shafts 83 and 85. All rolls are ofthe same diameter and are driven at the same speed, the upper set turning clockwise and the lower set counterclockwise, so as to draw the'cards between them.
  • Each upper. pair of rolls is downwardly spring-pressed against the corresponding lower set by adjustable spring clips 92. It is found that this conveyor system insures that the exact distance between cards will be maintained throughout their travel which is an essential feature in the operation of my invention.
  • the Peirce combinational hole system may be understood by reference to 4 and 5 ioo which show a typical control zone of a card, and the Peirce code for numbers, respectively.
  • FIG. 5 An inspection of Fig. 5 shows that the use of either one or two holes, and four positions, can be made to designate all of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.
  • I have designated the four positions by letters A, B, and D.
  • Reference to Fig. 5 shows that a single hole 111 D pos tion means 0, while a singlejhole 1n Apos1- tion means 1; in B positlon the single hole means 2 and in C position 5.
  • Two holes one at A and one at '0 mean 3, while two.
  • ach brush holder 101 carries either oneol two contact brushes'104, which bear on the top surface of cards 103 passing between the conveyor rolls. Rods 100 are so placed that each card passes under a set of brushes 104 just before it reaches'eath receiving station as will be more fully described. If no card be present the lower end of each brush 104 rests on a metallic contact strip 105, supported -.by the non-conducting block 106 rigidly secured to the frame of the machine. There is an individual contact strip 105 for each individual brush 104.
  • Adjacent each receiving station except the final or Reject station is a magnet 107 having two opposed but similar windings, the purpose of which will presently be explained. Controlled by each magnet is a deflector plate 108' hinged on rod 109 and carrying downwardly extending arm 110 drawn to the right by spring 111.
  • Extending lengthwise of the machine is a push rod 113 actuated by cam.112 through roller 114 carried by block 115 on the end of rod 113..
  • the rod 113 is pushed to the left by the cam and returned by spring 116 four times for every revolutionof the picker drum or once for every card cycle.
  • the push 'rod carries a pin 117 so positioned that when rod 113 is pushed to, the left pin 117 will carry with it arm 110,'w-hich isattached to deflector 108 and thereby lower the upper end -of the deflector below the plane of passing cards.
  • Each magnet 107 is providedwith an armature 118 carried on an arm 119 pivoted at 120 and having on its end opposite from the armature a shoulder 121 this end of arm 119 being drawn downwardly by spring 122. If a magnet 107' be energized when arm is in .its position to the left it will draw down armature 118 thereby causing shoulder 121 to engage the lower extremity of arm 110 andhold it.
  • Fig. 7* my motor is started by depressing button 127 and stopped by depressing either of the stop buttons 128 one at each end of the machine.
  • a card controlled device serves to stop the machine automatically should the'supply of cards be exhausted. Thisis shown conventionally at 129.
  • Magnets 107 are wound with two equal opposing coils. If equal currents are passing in both coils they will neutralize each other and the magnet is not energized. If, however, the coils are unbalanced the stronger coil will energize the magnet and actuate the armature.
  • Diagrams 7 and 7 show the circuit arrangement.
  • Single brushes are each connected in series with one magnet coil of the corresponding magnet while each pair of brushes is in multiple series with its magnet coil.
  • Figs. 7'and 7 that every brush and" every opposing magnet coil has a resistance in series with it. These resistances are so adjusted as to allow equal currents to flow through both coils of a magnet only when the proper card is under the corresponding brush or brushes.
  • the members 10 and 20 placed beside each resistance in Figs. 7 and 7 represent the units of current that each corresponding resistance allows to pass. These members 10 and 20 are illustrative only and may be replaced by any others having the same relationship to each other.
  • Contact mechanism 124 is so timed as to send an impulse through the control circuit once for every card cycle, the impulse occurring while the control zone of the cards is under the brushes. If at that instant a brush or pair of brushes rests on a blank card so as to make no contact through the card with their contact strips 105 then no current flows through the brush coil of the magnet winding, the magnet will be energized, its armature actuated and the deflector held down so the card will passon to the next station for further examination.
  • the stations are arranged in the order 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, so the cards will pass through the two-brush analyzing devices before reaching the one-brush stations (except station 5). Otherwise some single brushes would actuate deflectors by making contact through single holes of two hole combinations. For instance, the two-brush would act for all cards having holes in B position thus including all 4, 7 and 8 cards. However, due to my sequence of stations all 4, 7 and 8 cards are sorted before the 2 station is reached. A somewhat special arrangement is required at the 5 station to prevent the single 5 brushatC position fromdeflecting the 3 cards into the 5 station. This arrangement comprises an extra brush and resistance at position A but with the resistance in the lower magnet coil adjusted to pass only lOunits of current.
  • My device may also be used for selecting only cards having only one particular hole combination in the path of the brushes, as
  • Another valuable feature of my present invention is its abilityto sort in more than one column at a t1me,m one run. This is possible on account of havlng a settable brush at each station.
  • the operator wants to take out all cards having the 9combination in the first column, and all those having the 2' combination inthe seventh column, At the'9 station the brushes are positioned to. the first column, and at the 2' station the brush is positioned to the seventh column. All other brush circuits are opened. Then when thecards are run through all cards with 9s .the first column will go to station 9.
