Definitions

  • This invention relates to improvements in arrangements for sorting perforated cards used for statistics book-keeping and the like.
  • Fig. l is a side view of the essential parts of the arrangement.
  • Fig. 2 is a detail in side View and on an enlarged scale
  • FIG. 3 a front View of the detail shown in Fig. 2;
  • Fig. 4 is an elevation illustrating the pawland-ratchet mechanism and the electric devicescontrolling its operation
  • Fig. 5 is a detail View of a chute over which the perforated cards travel and of feelers co-operating with said chute.
  • a plate 1 consisting of a horizontal portion for supporting the perforated cards to be sorted and of an inclined chute, is arranged between parallel walls (not illustrated) carrying a number of shaft-bearings.
  • the cards are then grasped by rollers 6 and rapidly fed down the chute and through a channel 7 into a charger 8.
  • the apparatus for feeding the cards to the chute is immaterial to the present invention; in fact, the operator may insert them by hand, one by one; but it is essential that they be spaced longitudinally from each other, and that the feeding be synchronized with the reciprocations of the feelers 9 and 10, described below.
  • the essential mode of operation of the arrangement consists in that a feeler 9, which is adapted for electrical contact with the chute and underneath of which the edge of the card passes, is lifted up, so that its circuit is interrupted, a relay magnet 34 being arranged in the said circuit. VVhen.the relay armature is withdrawn from its magnet 34 as by a spring at, it closes a gap (at b) in another circuit in which a feeler 10 and a feed magnet 11 are arranged.
  • feeler 10 is movable transversely of the card feeler l0 and the chute 1.
  • the moving card which by breaking the contact at the feeler 9 has closed the circuit which includes the feeler 10 and the magnet 11, generally interrupts But as each hole of the card passes in registry with the feeler 10 the latter comes into contact with the chute, whereby the armature of the magnet 11 is each time at tracted and by means of a lever mechanism and a ratchetwvheel-pawl swings the charger or distributor 8, so that its mouth is brought above the next compartment of a group of sorting compartments 12.
  • the feeler 10 is four times electrically connected with the chute and four current-impulses are imparted to the magnet 11, and thus the armature of this magnet will feed the distributor 8 four times or four steps, so thatitis brought above the fourth compartment and therefore deposits the card in the same.
  • the card ought not to pass too fast under the feeler, therefore the speed by which it is fed through the rollers 6 ought to be limited and consequently also the efficiency of the machine.
  • the feelers 9 and 10 at the time they move in the same direction'tdown) as the passing card are taken along at a smaller speed, so that they lag behind the card. Therefore the speed of the card has to be increased with the speed of the feelers, without however increasing the ratio between the speed of the card and that of'the feelers. Therefore the holes pass below the feelers at a comparatively slowspeed, while during the upward travel the feelers move quickly over the chute.
  • the feelers After the passage of the card, the feelers are very quickly returned into the initial position, where they are ready for receiving the next card.
  • the feelers 9 and 10 are spaced longitudinally from each other by a short distance to allow sufficient time for the lever 33 to move switch 6 into closed position before the first perforation is encountered by feeler 10.
  • the slower downward and faster upward movement is imparted to the feelers 9 and 10 by arranging them on a rackslide 13, which is operated by a toothed wheel 14.
  • the latter is operated by a toothed segment 15, oscillating about a shaft 16 and furnished with a slot, which is engaged by the pin of a crank 18.
  • the arrangement for attaining this object consists of a' ratchet wheel 19, on which operates a pawl 20, the latter being pulled down the distance of one tooth whenever the leverarmature 0 moves away from the magnet 11.
  • a ratchet wheel 19 on which operates a pawl 20, the latter being pulled down the distance of one tooth whenever the leverarmature 0 moves away from the magnet 11.
  • the pawl feeds the ratchet wheel the distance of one tooth, whereafter said wheel is'held by a.
  • the pin 27 of the slide22 contacts with the side-wall of the wedge-shaped recess at a place, which corresponds to the position of' the member 28 and turns the latter about its axis to an extent enabling the pin 27 to reach the narrow or inner end of the said recess.
  • the member 28, provided with the wedge-shaped recess takes up a position corresponding to the position of the slide.
  • a cam 32 forces the wedge-shaped end of a rod 31 into the toothed port-ion 30 of a curved member, which is connected with the member 28 and disposed at the side of the distributor 8.
  • the dlstributor which is swung into a position corresponding to the position of the ratchet wheel 19 with a quick motion, solely by the operation of the cam 25, is immediately thereafter locked by the action of the cam 32, until the card has dropped into the corresponding compartment 12, while in the meantime the ratchet wheel 19 can be fed by the next card.
