Definitions

  • This invention relates to accounting machines and more particularly to machines of the record controlled type.
  • the invention relates to improvements to an automatic punching machine of the type disclosed inPatent 2,104,542, granted January 4, 1938, to C. D. Lake.
  • An object oi the invention is to improve the prior machine so that a saving in time and mechanism may be accomplished in the performance of the functions of the machine.
  • Perforated record cards are fed through the machine and during so-calledcard feeding cycles data is derived from the cards and entered into Upon completion oi the sensing of a group of cards, socalled group control mechanism will come into action to bring about total taking operations or the machine may be caused to stop so that such further operation may be manually initiated.
  • An auxiliary punching machine is provided which is brought into action upon the completion oi card feeding operations, and under control of the,
  • a specic object of theinvention is to reorganizev the total printing and punching circuits of an automatic punching machine, so that print and punch controlling circuits may be completed through an accumulator concurrently to control non-synchronous printing and punching mechanisms during a single cycle ⁇ of operations.
  • Fig.l l is a Wiring diagram of the improvements showing the manner in which they are applied to the prior art machine.
  • Fig. 2 is a timing diagram of the controlling impulse emitters for the printing and punching mechanisms.
  • the tabulating machine of the Lake Patent 2,104,542 comprises two mechanically independent units known as the tabulating machine and the punching machine, each'with its own independent driving motor. That for the punching machine is designated M.
  • M the punching machine
  • TM and RM two motors designated in Fig. '7 of the patent.
  • motor TM When motor TM is in operation, record cards are fed singly past sensing brushes and the data thereon entered into an accumulating mechanism, wherein a setting is eiTected representing the total amount entered in the accumulator.
  • Fig. 1 The mechanism upon which the total is represented is diagrammatically represented in Fig. 1 where 50 represents brushes which are diiierentially displaced by the action of the accumulator to take a position bridging individual commutator segments 49 and common conducting strips 52.
  • a set of digital segments 49 and a common conducting strip 52 are provided for each denominational order of the accumulator as indicated in the four orders shown, so that, where a total of 2851 is entered into the accumulator, the brushes 50 in the rela-ted orders Will be positioned as shown in Fig. 1.
  • the invention relates only t0 the devices for reading out the totals standing inthe accumulator, it is 'not necessary to describe in detailthe detailed manner in which the brushes 50 are displaced as they might obviously be manually adjusted.
  • the tabulating machine also contains printing mechanism containing type bars which are moved to cause digit representing type to successively pass a printing position.
  • Print controlling magnets H are provided which, when energized, will interrupt the type. bars and the particular type selected for printing willdepend upon the timing of energization. of the print magnet Il.
  • This printing mechanism is shown in detail inFig. 1 of the Lake patent and is driven during total printing operations froma motor ⁇ RM which drives the printing mechanism through a clutch controlled by a magnet
  • the controlling shaft 25 is" rotated, and this shaft has a commutator brush 56 which makes connection between commutator segments 51 and a common conductor 59.
  • the operation of the brush 56 is synchronous with the printing mechanism so that the brush contacts the segments 5l in the order 9, 8, '7, 6, etc. as the corresponding type elements arrive at the printing position.
  • a generator is provided for the purpose of the present invention. This generator is driv-en from the motor RM and has its positive side 0
  • the segments 51 are connected by wires
  • circuits Will be completed to the print magnets at time dependent upon the setting of the brushes For example, when brush 56 is at the 8 segment 51, a circuit is traceable from generator
  • Energizationof magnet at this time will interrupt its related type bar to position the 8 type element for printing.
  • This magnet 16 is not energized through the circuit traced as the rectier or unidirectional current flow unit
  • 06 is provided so that current cannot branch to the common wire I
  • the magnets 16 are contained in the punching mechanism which is operated by the motor M through clutch mechanism controlled by the magnet 92.
  • the clutch mechanism is modified so as to engage upon energization of magnet 92. preferably by making the clutch driving and driven parts like those in the tabulating machine so that, when magnets
  • FIG. 1 of the Lake patent shows that the clutch in the tabulating machine is of the multiple tooth type and the modification of the clutch in the punching machine involves making the clutch also of the multiple tooth type instead of a single tooth clutch as in the patent.
  • clutch may vary, with the preference being that both clutches have multiple teeth so that, when the clutch magnets
  • this punching machine cards are adyanced past a row of punches and, depending upon the time of energization of the punch controlling magnets 16, perforations will be made in the card in accordance with the setting of the brushes 50.
  • In the punching machine is a commutator brush 62 Which rotates in synchronism with the passage of the card past the row of punches.
  • This brush contacts commutator segments 63 in the order 9, 8, 7, etc. as the corresponding card positions are in line with thepunches, so that, for example, When the brush 62 is at the 8 segment 63, a circuit is traccable from generator
  • 05 is provided so that current cannot branch to the common wire
  • the printing machine was sent through a cycle of operations to print the amount and thereafter the punching mechanism was sent through a cycle of operations to punch the amount.
