Definitions

  • This invention relates to devices for perforating record cards. More specifically the invention is concerned with improved devices for reproducing and gang punching record cards under control of other perforated cards.
  • An object of the invention is to provide card feeding and punching devices capable of operation at high speed for reproducing and gang punching perforated record cards.
  • the punches are arranged in a single line across the length of the record card so that only twelve steps of movement are needed to completely punch a card, regardless of the columnar capacity.
  • a Geneva drive gear feeds the cards with intermittent and gradually accelerated movement.
  • Another object of the invention is to devise class selection devices for control of the punching devices so that data of a certain class on the original cards may be punched in a different field or eliminated in transferring the data to the blank cards.
  • the classification of the data on the original or master cards is denoted by the presence or absence of a special perforation.
  • the special perforation in an original card may also control selective punching in fields not receiving master or pattern card data but adapted to receive fixed data controlled by timed cam contacts which are closed as a certain index point on the blank card passes the punches.
  • the special perforation controls operation of connections between the contacts and punches.
  • one or more zero perforations or other index point perfora-tions may be selectively punched in any column or columns of a blank card under control of 5 timed contacts and a special class selection perforation in an original card.
  • Another object of the invention is to provide devices for checking or verifying the perforations in the punched cards to make sure that they agree with the data on the original record cards.
  • the machine stops and a light flashes to indicate the error to the operator of the machine.
  • the record cards are fed in synchronism from two feed hoppers.
  • An interlock prevents starting of the machine until cards are in both hoppers.
  • the one hopper contains the pattern or original cards which are already perforated .39 and the other hopper holds the blank cards which are to be perforated to correspond to the original cards.
  • a pattern card and an associated blank card are simultaneously placed in related feeding rollers 55 and then moved along concurrently and in syn- REISSUED chronism, the blank card having an intermittent movement.
  • the pattern card passes a sensing station and the blank card passes a punching station.
  • the cards are of the regular Hollerith form and are fed laterally across the 5 short width with the twelve index point position leading so that if a class selection or other control function is to be exercised by a special hole in the eleven or twelve position, the punching may be controlled as it follows thereafter. 10
  • the blank cards pause momentarily at each index point position so that if a perforation is to be reproduced, the punch has time to penetrate and withdraw from the punched card.
  • the intermittent motion of the card is brought about 15 by the use of a Geneva step motion gearing connected to the card feeding rollers.
  • the blank card is drawn under a single line 'of punches, there being one punch for each column of index points on the card, the card moving to 20 bring the various digit index positions successively under the punches.
  • the pattern card is passing over a single line of sensing brushes.
  • Each sensing 25 brush is connected to a magnet for controlling a related punch.
  • the pattern card is sensed at each line of index points and if a perforation appears, a circuit is established through one of the punch control 30 magnets the armature of which is connected by a call wire to an interposer pawl articulated on the end of a punch plunger.
  • the pawl has a shoulder normally out of the path of a positive actuator which is reciprocated as each index point is sensed. If the pawl is selected, it tends to engage the actuator and does so when the actuator lowers out of the way of a cam face on the pawl. Another cam face on the pawl cooperates with a stationary bar to hold the pawl positively into engagement with the actuator during the punching and retracting movement.
  • the first line of index points sensed on the pattern card may contain a special perforation to exercise the special controls of class selection, class elimination or field selection of the data to be reproduced.
  • class selection data on one field of the pattern card may be directed toeither of two fields on the blank card according to the classification of the data.
  • classification is denoted by the presence of the special hole which controls the shifting of contacts to change the direction of data to another field on the blank card.
  • class elimination data on the pattern card may be directed to the blank card by closed contacts or eliminated by opening said contacts according to the classification of the data.
  • the presence of a special perforation may serve to open or close such class elimination contacts.
  • field selection data on either of two fields on the pattern card may be selected and directed to one field on the blank card according to the classification of the data.
  • the punched cards may be checked or verified to make sure they agree with the pattern.
  • the pattern and punched cards enter checking sensing stations after passing through the respective sensing and punching stations.
  • the cards are fed in synchronism, with line after line of index points passing over the two lines of checking sensing brushes. When perforations fail to coincide, the machine is stopped and a light indicates the error to the operator.
  • the class selected data may also be checked.
  • the punching and checking stations through which the blank cards pass may be used for gang punching.
  • a perforated master card is placed at the bottom of the hopper beneath a bunch of blank cards which are to receive the data on the master card. Then the master card is fed under the punch and over to the sensing station.
  • first blank card following the master card is fed under the line of punches as the master card moves in synchronism over the sensing brushes.
  • the punches are operated under control of the sensing brushes to punch the blank card as a duplicate of the master card. This operation continues as the following cards feed, the cards being punched successively to correspond with the preceding card.
  • a number of master cards may be interspersed between the blank cards for successive gang punching operations of more than one group-of cards. For such use the master card has a spe cial perforation which control devices for disabling punching between groups while the incoming master card passes under the punches and over to the sensing brushes.
  • the field selection controls described hereinafter as applied during reproducing may also be effected during gang punching. Then a special perforation in the master card directs the perforated data in a selected field on the master card to the proper field on the following gang punched cards.
  • the machine may be conditioned for combined gang punching and reproducing control. Then the blank cards are adapted to be perforated with data from two sources, the master card which precedes them and the pattern cards which accompany them. Several groups may be gang punched with continuous feeding without stopping when encountering each interspersed master card. This is possible because when a master card is encountered at the front of the punching station, control is exercised by a special perforation therein to hold up the feeding of the pattern cards for one cycle to allow the master card to proceed to the sensing station before combined punching is continued. During operation under combined control, checking may be done on the reproduced portion of the perforated records.
  • the special perforations in the pattern and master cards may be reproduced, transferred or eliminated in the control of punching record cards.
  • Regular data perforations may appear in the same column with the special perforation 0n Pflttem or master card, and these perforations may also be selectively reproduced, separately transferred or eliminated.
  • Connected with the devices sensing the column containing the special perforation are contacts which close one line and open another as the sensing means passes from the two special index positions to the regular numeral data positions on the record cards. These lines may be connected to any column positionin the punch or disconnected therefrom.
  • Another feature of the invention is the checking of class selected perforations in the record cards. Even though the record cards may be perforated in either of two fields under control of a single field on the pattern cards, the checking devices are adapted to switch the connection to the sensing brushes cooperating with the proper perforated field and thereby check the class selected perforations with the original perforations in the pattern card.
  • Another improvement is in the means for stopping the machine when card feeding fafls in either hopper, and the automatic selective operation of feeding only in that hopper, on depression of a start key, until a card is fed.

  • FIG. 1 A general idea of the operation of the devices of the present invention may be gathered by observing the diagrammatic view shown in Fig. 1. There it is noted that there are a number of pattern cards ill in the hopper R. and another bunch of blank record cards II in the hopper P. The cards are fed singly but concurrently from both hoppers and are then shifted in synchronism across sensing and punching stations before being deposited in stackers i2 and IS.

  • a number of master cards are interspersed in the blank record cards II in hopper P.
  • the operation that follows is substantially the same as with a single group, the only difference in operation occurring when an interspersed master card passes under the punches l3.

  • both sections of the machine are used.
  • the cards I l are operated upon as described hereinbefore, the only difference being that a number of the punches I8 are controlled by the pattern card I and brushes 15, while others of the punches l8 are controlled by the gang punching master card and brushes l3.
  • only certain of the brushes l and I9 may be used for checking the reproduced portion of the perforated data.
  • Fig. 8 shows a portion of a perforated card.
  • a perforated card may act as a pattern card or a master card. It is noted that the card is perforated with the number 648. It also contains a special perforation or R hole at the twelve position in the 7th column. Other special perforations known as X holes may be punched at the eleven index position in any column of the card.
  • record card col and index points appear in the claims, it will be understood that they mean that the record card is divided into parallel columns (as illustrated in Fig. 8) each column having nine or more different positions or index points. Each index point represents a different value by virtue of its location from a reference edge of the card, so that when a perforated card is analyzed by passing it through a tabulating machine in a columnar direction, or analyzed at rest, the index points will control associated representing devices.
