Definitions

  • This invention relates to methods of and apparatus for perforating and verifying record cards for use in statisticalor like machines.
  • a perforating machine usually comprising a key board, the keys of which are operated to actuate punches.
  • the card is ultimately used in a tabulating machine, which is a machine which translates the. holes into printed ciphers reproducing on a 1 6 printed sheet a copy of the original data.
  • the holes which have been punched in the record card have to. be verified, that is checked against the original data before they are em- Sometimes this is done by a visual inspection of the cards.
  • Lighting means are arranged under the plate, so that if the card is correct all holes are obscured, if incorrect the light shows through incorrect holes, in which latter case the card has to be verified by comparing it with the original data and either making a new card or correct- 4 ing the old card by making the full perforations necessary so that the record is correct.
  • a method of producing individual records on a record card or the like particularly for use in statistical machines consists in forming the individual records in a plurality of recording stages (e. g. two) complementary to each other.
  • Complementary punching according to the invention may be effected by producing the normal round perforation in two stages, for instance, by punching a semi-circular perforation in the first stage and the other half of the hole in the second stage. If, at the end of the stages of perforating the cards, any half circular perforations are visible, the card contains an error.
  • punching machines as at present employed may be used for obtaining the usual round hole, and then the sec-- ond punching operation may produce a slight irregularity in the hole.
  • the finished record hole may be of the shape which resembles the section of a feathered shaft if the second punching is done with a rectangular punch.
  • the first punching may be done in a machine with punches of a smaller diameter than those usually employed and the second punching operation done with a larger punch, namely one of the normal size, but in such case viewing the cards would only detect errors of omission, namely errors constituted by punching in the wrong holes.
  • the second punching operation done with a larger punch, namely one of the normal size, but in such case viewing the cards would only detect errors of omission, namely errors constituted by punching in the wrong holes.
  • it is essential to detect errors of omission it is preferred in constructions according to the invention to employ machines for complementary punching, which leaves holes of a shape differentiating between correct punching and incorrect punching.
  • a perforation obtains by reason of the two punching stages. If they agree, then the punching is correct and checked; if they do not agree then the card has to be referred to the original data to see where the first punching operation was incomplete or incorrectly effected, and then the second stage punching has also to be verified.
  • the shape of a record may be defined as a plurality of spaced apart holes of the sameor different shape and/or size, punched in a plurality of recording stages complementary to one another.
  • a record may comprise two spaced apart perforations of similar shape and size, one of which is punched in the first stage and the other in the second stage, whereby punching in both stages is correct when the'pair of perforations appear, and punching in one or other of the stages is incorrect when one of the perforations is missing.
  • Apparatus for punching according to the present invention may be machines of the type described in British patent specifications Nos. 328,281; 328,255; 328,285, 321,952, and 321,953, two such machines being usually employed for carrying out the punching operation, one machine having one part of the punch and the other machine the complementary part, thereby punching is effected and a comparison attained by employing the skilled operatives of punching machines during punching operations, whilst the final viewing may be efiected by unskilled hands which merely have to look out for holes of wrong shape, which most easily and satisfactorily can be effected by viewing the back of the cards.
  • the individual records are formed by contiguous offset perforations, the shape or size of which depends on the shape or size of the punches employed.
  • the accompanying drawing illustrates one form of apparatus, by way of example, for varying the feed of the cards to the punches of a punching machine, so that offset punching may be obtained.
  • FIG. 1 is a perspective view showing an adjustable stop plate for the cards, on the discharge side of the machine;
  • Fig. 2 is a side view showing the throw of the eccentric of the stop plate of Fig. 1 the operating mechanism being removed for clearness.
  • a card is fed as customary between die plates 1, 2 containing many perforations as it is possible to make in a card, while 3 is a vertically reciprocating stop plate on the discharge side of the machine, which positions the card beneath the punches 4.
  • the reciprocating stop plate 3 is made adjustable by mounting the plate to pivot on a vertically reciprocating memher 5 for the stop plate, by means of a spring 6 engaging in a recess '7 of the lever 5, the plate 3 being slotted as at 8 to engage over the member 5 as shown.
  • a rod 9 extending transversely of the machine and rotatably mounted in brackets 10 on the frame of the machine is provided and eccentrically mounted on the rod 9 are a pair of levers 11 pivoted at their free ends 12 to right-angled brackets 13 on arms 14 of the stop plate 3.
  • the rod 9 at one end is provided with an operating knob 15 and has mounted thereon against the bracket 10 a setting plate 16, having recesses 17 and 18 adapted to be engaged by a roller 19 on the end of a spring pressed lever 20 pivotally mounted on the bracket 10.
  • the roller 19 In the normal position of the parts as shown, the roller 19 is resting in the recess 18 and the top ends of the arms 14 of the stop plate 3 are in the vertical position giving a normal feed of the card.
  • the spacing of the recesses around the plate 16 is such as to permit only of the proper rotation being given to the rod 9 to ensure that the top ends of the arms 14 are displaced the correct amount and accurate offsetting of the cards obtaining.
  • stop plate 3 is reciprocated vertically at the proper time in a cycle, in well known manner from the main shaft of the machine, the stop plate being lowered subsequent to punching to permit of the card being passed to the eject feed rollers ER which feed the cards to a suitable receptacle (not shown).
  • one of the punching operations may be substituted by a printing operation, preferably effected in a machine having keys of exactly the same nature as in the punch.
  • the printing may be effected on the back or front of the card, or both, and then either the previous or subsequent punching operation efiected.
  • a spot may be printed.
  • the invention may be applied to the production of cards which are read by sensing apparatus involving the employment of actinic light, that is to say, the reflection or non-re flection of the light from the card determines, by varying the resistance in electrical circuits, the
