  • This invention relates topunching machines and more 'particularly'to'- the type adapted -to Vpunch cards for controlling tabulating'andstatistic'al machines.
  • 'I'he main object of the invention is to provide a punchingsystem in which a single punching machine is capable vof fulfilling the sequential punching requirements ot ⁇ more thany one operator.
  • a v vA Astill further object of the invention is to selectively call the punching Vmachine into operation in a sequence that ycorresponds to the opera tors.- completion oi their digit registrations. This increases the eillciency'of output of the operator since -the operator may immediately recommencesettingup digit registrations ofthe v ⁇ next data Vwithout "awaiting completion of punching operations.
  • Another object of the invention is to coordinate with a plurality of operators keyboard digit registration stations' a punching machine Vwith such high speed punching capabilities and' character-Y istics. That it is able to complete ⁇ punching ofv cards under control of two or-more stored digit registrations without holding up any operatori More specifically this object is attained by'utillz-Y ing aV punching machine inzwhich the cyclic operation'thereoffis constant :irrespective of the number of denominational card columns which are punched.
  • the punching machine shown is capable when in commercial use of punchingcards atv the rate of onehundred per minute and the cyclic operation of the machine is so short relative to the time for digit setting that punching operationsV are completed without holdingupthe operators.
  • Y a' In connection with the sequential operation ofthe punching machine, a more specific object of theS invention is attained by causing each operator-sstation'to transmit a signal to the sequencing unit which stores up the signals in the vsame sequencethey are received from the operators stations, when' they are'transmitted dissimultaneously.
  • the sequencing .unit then causesQthe vreading out ofthe digit registrations to .the punchingmachine'in the. ⁇ same sequence that they are completed to thereby punch cards in the same sequence the signalsare storedup.
  • the sequencing Vunit also provides ⁇ for punching lout of the digit registrations in a predetermined orde; ⁇ in the event 'thattwo or more signals are transmitted simultaneously.
  • Another'object of .the invention isvthe provision in"each"operators station of two digit storage associated'with thekeyboard'of the associated station -andis set lup to represent the digit key depressions.
  • the other storage device, or secondary is associated with the punchingmachine through the sequencing unit when the latter calls it into operation and means is further provided to effect a digit transfer from the primary storage device to the secondary storage device. This transfer operation clears out the primary storage device and it is then in condition for the reception of digit representations of the next data.
  • a still further object'of the invention is to concomitantlyr transmit a signal to the' sequencing unit vupon suchfdigit transfer operations, giving an indication that-when the punching machine has.Y terminated' its cyclic operation the digit registrations of a secondary storage device may be read out if the sequencing unit determines that such registrations should be picked vup and read out.l
  • a still further object of the invention' is to "'eilect a denominational shift when digit registrations are transferred from the primary storage devicesl to the secondary storage devices.
  • primary storage devices maybe set up* to representy two different numbers which .varyin de nominational size and in registrations of the numbers beginning at the higher denominational digitsoi' the number, the units digit will be entered in an order'of the storage devices which varies with the sizefof the number.
  • a denominational shift mechanism correlated with the primary and secondary storage devices obviates the necessity of making a I more toldetails of construction 'but which should be considered as relatively important objects is toV provide the operator .with signal devices which indicate erroneous operations and the4 condition of the primary and secondary storage devices.

  • One of such devices consists of a signal light
  • the secondary storage devices are associated with the punch time that the operator attempts to make further' key depressions after setting up the digits of the bank number without depressing amanual bar.
  • a more specific object of the inventionl relates to the skip circuit arrangement provided which eliminates the necessity of the operator ofpunching the 0 key for denominational orders vto the left of the ilrst signicant digit. In this respect. the operators speed is increased because lunnecessary key depressions are eliminated, although as will be more apparent later'on, such higher denominational columns are, nevertheless,

  • a spacing procedure may then bev generalized by saying that as one column is set up it partially completes the pickup circuit to the column o1' the next higher order and breaks the pickup circuit to the column previously set up.
  • the purpose of the alternating relays Ci and C2 is to prevent the previously described closure of an A, B. C, etc., contact in the next lower column from causing an undesired progression in that column.

  • relay coil L is energized to open contacts LI to prevent an undesired digit setup in column V11 when column 12 is being set up.
  • CARD FORM A consideration of the card form illustrated in Fig. 16 shows that a portion of the card to be punched consists of twenty card columns of which columns 1 to 8, inclusive are prepunched, preferably by gang punching to indicate common data for a series of cards. The remaining card columns 9 to 20, inclusive are punched ⁇ under control of the storage columns l to 12 of each station. Card columns 9 to 20, inclusive, are subdivided into two fields, columns 9, 10, 11 andv l2 presenting the paying bank number which is indicated on the check. The amount of the check which, of course, is taken from the check is punched on the card in columns 13 to 20 under control of storage columns to 12.
  • the bank number and the check amount may vary in the number of significant digits which comprise each amount, and by the present novel digit shift arrangement it is possible to ⁇ punch the numbers in the correct. denominational relationship on the card and in the proper columns thereof without requiring the operator to punch the zeros at the left.
  • the bank number consisted of only two digits these are set up in denominational columns 1 and 2 but by a denominational transfer means to be subsequently described card columns ll and 12 are punched to represent thev tens and units of this two-digit number. Depression of the 0 digit key is unnecessary and therefore time is saved in this elimination.

  • Depression of the manual bar has the capability of conditioning the relays C
  • This willbe made clear when it is assumed that the bank number contains three digits and after the third digit setup in storage column 3 relay ACI (Fig. 3) would bein an energized condition. If relay ACI was permitted to remain energized the next operation of a digit key for storage column 5 would be treated as an even setup and relay C2 would energize.
