Definitions

  • the invention while adapted to various uses, will be illustrated and described in connection with the accounting systempf a public utility corporation supplying services in connection with electricity, light, power, gas and the like. It ls o customary to install meters on the premises of users of electricity and gas on which the Wconsumption of these commodities is registered. An employee of the corporation makes periodic visits to read the meters, entering the readings in'a meter read book which forms the book of original entry. This book shows the last previous and present readings of the meters and the dif-l ference between the two, representing the consumption of the commodity during' the selected period. According to the present invention it is proposed to form perforated ledger cards from these books of original entry.
  • the ledger cards are punched in differential locations, in the well known manner, to represent different data and ordinarily a single card is, prepared for the consumption of several commodities by each consumer during the accounting period.
  • each ledger card is punched. with identifying data of the consumer, identifying data ofthe particular 46 commodities, present and previous readings of the meters, thel differences between the readings, representing consumption during the period, and the amount due for this consumption in each commodity.
  • Suitable feeding mechanism is provided to feed the post cards to the printing mechanism of the tabulator while the perforated 5 ledger car'ds are fed through the accounting section.
  • the tabulator is provided with mechanism to accumulate data from successive cards and cause a total .to be taken of the items in the particular classification group. 10
  • the post cards are fed to the platen of the tabulating machine by special feeding mechanism and the present reading, previous reading, consumption and amount due for the consumption are printed on the post card from the per- 1o forated ledger card for one of the commodities.
  • the amount due is entered into an accumulator and at the end-of the billing operation the total of the amount due for the particular consumer is also printed on the post card.
  • the line spacing for the several items on each post card is obtained from the usual line spacing. mechanism of the machine.
  • the special feeding mechanism feeds the printed post card out of the 25 machine and feeds a blank post card into printf ing position to receive printed data from the following c ard.
  • the consumers itemized bills are obtained in convenient form directly from the ledger without any clerical or copying 30 work.
  • the particular method of handling the ledger cards may vary. Ordinarily after the ⁇ statements or bills are made and mailed the ledger cards are placed in a special'container and as each bill is 35 paid its particularledger card is withdrawn from the special container and placed in the permanent file. At the end of a certain period of time all the ledger cards remaining inthe special container which now represent overdue accounts are 40 again run through the tabulator and special follow up notices are printed from them in the same manner as the original bills were printed. These ledger cards y are then replaced in the special container and removed as before when the bills are paid. At the end of another period of time the ledger cards still remaining in the container may be again run through the tabulator to print special shut-oil' notices.
