  • This invention is directed to the general and of providing an improved means of placing a greater amount of statistical, or like data, upon a given record card than hasbeen heretofore possible, resulting in increased efficiency and benefits accruin from tabulating, or like machines prefera ly employed in connection with such record cards.
  • card cost and filing space are'important considerations, it is possible, by means of the present improvements 'to place on a record card of appreciably smaller dimensions the same statistical or tabular data placed on record cards of a size heretofore employed.
  • the spacing of adjacent card columns is reduced in order to provide a more data on a given card, and to provide for the necessary time element for electrical contact the holes are elongated in the direction of card feed.
  • the form and spacings of the perforations are such that considerable resistance to tearing by a series of such perforations is eifected.
  • Fig. 1 represents a card having the usual form and spacings employed in connection with Hollerith tabulating and sorting machines
  • Fig. 2 is a plan view of a perforated record card having index points constructed accordlng to the present invention
  • Fig. 3 is a cross sectional view of the brush section of a tabulator, sorting machine or the like, showing the cooperation of an analyz- 1ng brush with the preferred form of perforation of an improved record card as the card is fed-thereto;
  • Fig. 4 is a fragmentary portion of a record card employing small circular perforations
  • Figs. 5 and 6 are fragmentary portions of record cards illustrating modifications of the present invention.
  • the improved record card 10 (Fig. 2) is of the usual construction except that the index point designations 11 are spaced closer toof data required stren h-of the perforated card but The numbe upon a car by the closeness to which adjacent brushes may be brought together withoutjthe resultant danger' of-a brush associated .wlth one column, engaging an adjacent brush or column-perforation resulting in irregular accounting machine 0 erations.
  • the resent column width has een adopted with the above in mind and with slight modifications the brushes and holders now employed may be satisfactorily used in connection with the new form of record cards.
  • index point perforations 11 are substantially rectangular in which the len h is considerably greater than the width. ther forms may be. used with similar marked advantages and may besubstantially oval-shaped holes 16- shown in Fig. 5 or have adjacent straight edges along the longer sideand be substantially circular or elliptical on the other edges such as shown by numeral 17 in Fig. 6. i 7
