  • This invention relates to tabiilating machines. More specifically it relates to tabulating machines which may be employed to perform various functions, as will hereinafter appear.
  • Tabulating machines have'been heretofore proposed in which a stop card or stop cards are relied upon automatically to stop the machine, or otherwise modify its operation. At the end of each series of cards of a .particular group a stop card was placed.
  • the machines toward. which the present invention is directed relate to aclass in which control is secured directly fromindex points of the record cards themselves, such controlbeing efi'ected through automatic control devices.
