  • the carriage 15 is guided in its movement by a guide rod 16 disposed beneath the ramp, parallel to the latter and between the two tracks.
  • the upper card stop 14 As the cards reach the compartment and are stacked on the ramp, the upper card stop 14 is pushed back by the card stack and compels the carriage 15 to descend, thus compressing the spring 17.

  • the upper half of the compartment is used for the accumulation of the cards which enter the compartment, the accumulated cards then being carried into the lower half of the compartment by a feed mechanism which will hereinafter be more fully described.

  • FIGS. 2 and 3 also show that the lock 37 is equipped with a small plate 41, which has a notch for the passage of a steel twisted cable 42, on which is mounted a block 43, which will hereinafter be referred to.
  • the sorting machine which has been illustrated partly on the assembled FIGS. 1A and 1B comprises thirteen receiving compartments similar to that which has just been briefiy described. It is expedient to remember here that, with the first passage of the cards into the machine, those cards which are extracted from the card supply magazine are carried along and analysed in order to be selectively directed towards the receiving compartments. In accordance 'with a well-known sorting principle, when this first passage is completed, the cards are extracted from the receiving compartments, at the lower ends thereof, and replaced in the supply magazine in order once again to be distributed, during a second passage, in the receiving compartments. This operation is repeated until ,the number of successive passages required by the sorting operation is completed.
  • the cards which are distributed in the different receiving compartments and which are collected in the upper half of each compartment have to be lowered into the lower part of each of the compartments, in order then to be capable of being extracted from the said compartments by an appropriate automatic extraction device.
  • the descent of the cards into the lower part of each compartment is effected by means of a card-feeding mechanism, which will now be described by reference to FIGS. 1A and 1B.
  • the card-feeding mechanism consists essentially of a movable common carriage formed by two supporting plates 46 and 47, which are interconnected by a bar 48 extending transversely beneath the receiving compartments.
  • the supporting plates 46 and 47 are capable of sliding, by means of rollers, on the upper edges of the two U-shaped elements 49 and 50, these elements being fast with the frame of the machine and disposed on either side of the receiving compartment assembly, parallel to and slightly below the latter.
  • the supporting plate 46 is fast with a metal chain 51 which is stretched over two pinions 52 and 53 inside the element 49.

  • the said carriage which is hereinafter referred to as the lower carriage, can be driven by an electric motor M through a driving shaft 58 on which the pinions 52 and 55 are fixed.
  • the said lower carriage can be displaced in such a way that its bar 48 remains constantly perpendicular to the direction of its displacement.

  • each receiving compartment Associated with each receiving compartment is a second card support which will hereinafter be referred to as the lower card retaining device or stop, this being formed by two short bars 62 and 63 arranged along the path followed by the cards which descend by sliding on the ramp, these bars being fixed to the bar 48 of the lower carriage by means of two arms 64 and 65 respectively.
  • the short bars 62 and 63 which are fast with said carriage are displaced above the guide tracks and 11 and close to the latter, the said bars being however sufliciently spaced from one another to permit the carriage and the upper card stop 14 to pass between them.
  • the carriage 15 which will hereinafter be referred to as the upper carriage, is driven in its descending movement and passes between the small bars 62 and 6-3 of the lower card stop, the stack of cards which until then had slid on the ramp while being retained by the upper card stop is stopped in its movement by the lower card stop and then bears against the latter.
  • the travel of the lower carriage is limited, so that the lower card stop can only be effectively displaced between an extreme lower position close to the lower end of the ramp and an intermediate position disposed substantially equidistant from the two ends of the ramp.
  • the upper card stop can only be displaced between a limiting upper position and the said intermediate position, the descending movement, as far as the lower end of the ramp, of the cards collected in the upper part of the compartment is effected by driving the lower carriage upwardly and by driving the upper carriage downwardly, so that the upper card stop and the lower card stop arrive simultaneously at the intermediate position, the upper card stop then being rocked downwardly in order to permit the stack of cards thus freed to bear against the lower card stop.
  • the movement of the lower carriage is then reversed in order to permit the cards held by the lower card stop to be moved downwardly as far as the lower end of the ramp.
  • This system comprises essentially the steel twisted cable 42 which has already been referred to in the specification and which is mounted on two pulleys 66 and 67 (FIG. 4) disposed beneath the ramp and in the vicinity of the two ends of the latter.

  • FIG. 4 shows in chain-dotted lines the positions which are occupied by the upper and lower card stops which have reached an intermediate position, just before the rocking of the upper card stop.
  • the ramp In order that this rocking movement is effected quickly, even when the stack held by the upper card stop only comprises a very small number of cards, it is necessary for the ramp to have a sufiicient slope. In the example described, this slope is of the order of 35 and this in addition facilitates the sliding of the cards on the ramp.
  • the upward displacement of the lower carriage is limited by two stops 70 and 71, which are shown in FIG. 1A and which are adjusted in such a way as to stop the movement of the lower carriage at the moment when the lower card stop reaches an intermediate position.
  • the driving of the shaft 58 by the motor M is effected by means of a torque-limiting friction clutch system of known type.

  • FIG. 7 shows that, when the upper card stop is folded, the stud is disposed substantially beneath the pivot shaft 32 of the upper card stop. Under these conditions, when the upper carriage moves upwardly, this pin or stud encounters a fixed flexible stop 73 disposed along its path.
  • the stud 72 held during the passage by the stop 73, while the upper carriage continues to move upwardly under the action of the spring 17, causes the upper card stop to rock, as shown in FIG. 8.

  • the upper card stop is once again locked in the top position by the lower latch 33 which, because of the rocking of the said card stop, has been brought into engagement with the notch 36 under the action of the spring 35.
  • the previously described card-transport mechanism and the transmission system are so designed that the stack of cards which has moved downwardly with the lower card stop reaches the lower end of the ramp at the exact moment when the upper carriage again encounters the limit stop '74.
  • the cards, which have thus descended to the bottom of the ramp can then be extracted from the compartment by an extraction device of known type, such as that which is shown in FIG. 1B, at the bottom of the ramp of the receiving compartment close to that which has been shown in FIGS. 1A and 1B.
  • this device is of a well known type.
  • Said device comprises at least one conveyor belt tensioned by two guide pulleys rotating on shafts fast with a support, which is formed with openings communicating with an air vacuum source for applying the cards to the conveyor belt and ensuring that the cards are driven through a gauge when the said belt is driven by a driving mechanism, this latter being formed by a constantly rotating shaft, into contact with which the belt can be brought for being driven by the said shaft.
  • FIGS. 1B and 4 show that the cards which are moved to the bottom of the ramp are applied to the conveyor belts and '81 of the extraction arrangement.
  • the lower carriage can be moved downwardly to a slightly greater extent, as shown in FIG. 4, so as to permit the lower card stop to be disengaged from the stack of cards, in order thus to avoid interfering with the subsequent extraction of the said cards from the compartment.

  • the upper carriage 15, held by the limit stop 74 can no longer be displaced towards the top of the compartment.
  • the block 43 is spaced from the small plate 41 and thus permits the locking member 37 once again to assume its position for locking the lower latch, under the action of the spring plate 39. From this moment, the cards which are bearing against the conveyor belts 80 and 81 can be extracted from the compartment, this extraction being controlled, in the example described, by an electromagnet EV which is shown in FIG. 1B and which, when it is energised, slightly displaces the conveyor belt assembly 80 and 81 to bring them into contact with a constantly rotating shaft 82.

If there is no card at the bottom of the first receiving compartment, the cell PHl receives a light beam emitted from a light source, which permits the relay BP1 to be energised with direct current.
