Definitions

  • ABSTRACT A unitary ledger handling device is provided for ready and convenient attachment to the forms handling mechanism of an accounting machine or the like, the accounting machine being effective for readably and writably processing ledger-type documents as well as for pnntably recording transactions on fan-fold or continuous journal paper.
  • the device includes a hOpper compartment into which the documents to be processed are manually deposited, a stacker compartment into which completely processed documents are automatically advanced, and a document hold position disposed contiguously downstream of the stacker compartment where partially processed documents are stored pending the generation of data to be recorded in summary thereon.
  • Means are provided within the unitary device for automatically feeding documents singly from the hopper compartment to the processing station of the accounting machine, for automatically advancing partially and fully processed documents from the processing station to the document hold position and to the stacker compartment, respectively, and for recallably feeding partially processed documents from the document hold position to the processing station to complete the processing thereof.
  • the account number, old balance, and line indication are magnetically read from the stripe, the account number and amount of the current transaction then being entered in the keyboard of the machine. Should the separately entered account numbers agree, the ledger would be advanced to the printing line selected by the magnetically recorded line indication, and the posting then completed both with respect to the printed information on the face of the ledger and the magnetically recorded information on the reverse side.
  • An important aspect of the invention is the provision of a unitary ledger handling device that is readily attachable to the journal handling mechanism of an accounting machine, the device including a hopper compartment, a stacker compartment, and a hold position particularly suited for storing partially processed ledgers, the hopper and stacker compartments being complementary to one another within a predetermined depth space dimension and separated by a pivotal divider.
  • the hopper compartment is pivotally biased to hold the leading ledger therein in movable contact with ledger feeding means, said pivotal biasing serving also to gradually minimize the depth space dimension utilized by the hopper compartment and to optimize the depth space dimension utilized by the stacker compartment as ledgers are fed from the hopper compartment to the processing station and to the stacker compartment.
  • automatic ledger advancing means including a self-contained reversible motor, a plurality of rotatable roller-supporting shafts including a plurality of pulleys, and a plurality of one-way roller clutches for feedably advancing ledgers at two different speeds from the hopper compartment to the processing station, and for feedably advancing ledgers from the processing station to the stacker compartment.
  • Still another important aspect of the invention is the use of solenoid clutch means in cooperation with a first signal transmitted to the reversible motor for rotating the motor in a first direction and for activating a plurality of roller-supporting shafts at a relatively slow pick speed to thereby advance the ledger from the hopper compartment to the control of a more rapidly rotating roller-supporting shaft, the ledger being thereafter advanced at a predetermined faster speed to the processing station.
  • a second signal to the reversible motor is effective for rotating the motor in a second direction to thereby activate a separate plurality of rollersupporting shafts to advance the ledger from the processing station to the stacker compartment.
  • Yet another aspect of the invention is the provision of means operable independently of the solenoid clutch means, upon transmission of a first signal to the reversible motor, for recallably advancing a ledger from the hold position to the processing station, the ledger having storably come to rest between at least two of said separate plurality of roller-supporting shafts and their associated idler rollers upon the premature termination of a second signal, such termination of the second signal having occurred while the ledger was in transit between the processing station and the stacker compartment.
  • FIG. 1 is a left side sectional elevation of a preferred embodiment of the unitary ledger handling device showing the arrangement of the hopper and stacker compartments, the first and second guide means, and the arrangement of the various shafts, pulleys, gear and rollers that are utilized for transporting ledgers as be tween the hopper compartment and the processing station and from the processing station to the stacker compartment;
  • FIG. 2 is a rear view of the preferred embodiment of the invention showing the relationship of the unitary device to the pin-feed or journal handling mechanism of the accounting machine when in its mounted state thereon;
  • FIG. 3 is a right side perspective view showing the reyersible motor mounted on the right side frame of the device and various of the gears and parts that are associated with the ledger feed means effective for advancing a ledger from the hopper compartment to the processing station;
  • FIG. 4 is a right side perspective view showing the gears and parts of FIG. 3 in greater detail;
  • FIG. 5 is a left side fragmentary perspective view showing the relationship of the various shafts, pulleys and gears that are associated with the ledger feed means and the ledger stacking means;
  • FIG. 6 is a front perspective view of the unitary device as it would appear to an operator of the accounting machine on which it is mounted, a quantity of ledgers being shown in the hopper compartment with a single ledger in the process of being fed from the hopper compartment to the injection-ejection throat of the accounting machine.
  • the invention resides in the provision of a unitary ledger handling device that may be readily attached to the journal handling mechanism of an accounting machine for effectively automating the updating of business documents and particularly magnetic stripe ledgers, it being characteristic of such updating to interrupt the machine processing of individual ledgers and to store the partially processed ledger at a point removed from the processing station while data that is to be summarily recorded on the ledger is independently generated.
  • Attachment of the unitary ledger handling device to the pin-feed or journal paper handling mechanism of the accounting machine, generally indicated at 11 in FIGS. 2 and 3, may be accomplished readily by securing a pair of mounting brackets 13 to the pair of upright side frames 15 of the pin-feed carriage 11 by means of screws 17, the mounting brackets 13 being provided with apertures (not shown) for supportably receiving the ends of a support shaft 19.

  • the weight and gravitational force of the unitary ledger handler is also supported by a limit stud 31 secured to the right side frame member 25, as shown in FIG. 3, such limit stud gravitationally limiting against the right side frame 15 of the pin-feed carriage.
  • Each of the side frame members 25 of the inventive unitary device is provided with a freely pivotal latch 33 serving to gravitationally enclose the circular recess 24 of its associated side frame member to thereby retainably hold the unitary device securely mounted on the bearing limit members 21 of the support shaft 19.

  • Attachment of the inventive unitary ledger handling device to the pin-feed or journal paper handling mechanism of the accounting machine also requires attachment of a cable leading from the accounting machine to thereinafter described solenoid means and to an electric motor supported on the right side frame member 25, such cable attachment being accommodated by a mounting bracket 39 shown in FIG. 4.
