Definitions

  • This invention relates to devices for automatically feeding record material.
  • the novel devices are illustrated as an attachment for a perforated card controlled tabulating machine.
  • An object of the invention is to provide an improved form or automatic line spacing means.
  • Another object is to provide a simple and yet effective type of ejecting mechanism for feeding a printed form out of thecarriage of the machine and picking up a new form and bringing it intopodtion for the printing of the flrstitem.
  • the mechanism is constructed as a compact unit which is attached to andmovable with, the carriage frame. Wiring connections provide the means for establishing control between the regular tabulating mechanism and the record feedin devices.
  • a feature of the invention is the provision of means for controlling the spacing of the record material before and after the printing of totals.
  • the controls may be adjusted to suppress the feeding of .the record material so that the total is printedin line with the last item.
  • Other Bdjustments may be made so that a single or multiple line spacing operation may takeplaoe before and after' the printing of the total.
  • the line spacing devices are manually adjusted I to call for single, double, or triple spacing.
  • the .eifectingof such spacing is brought about under 5 electromagnetic control and a single impulse through the magnet brings about the single or multiple spacing of the record material.
  • An object of the invention is to make the ejecting mechanism settabie so that a variable number of items or totals may be printed on a form before ejection. Other adjustments may be made in the control of the eject devices so that a form ed below the usual allotted printing area on the form with theitems which preceded the total.
  • Another object of the invention is to provide a carriage with an adiustable head spaci feed ingmeanstoautcmaticallycarrytheupperport and printed on the following sheet. but is print- SOIIIII. (crass-m of a form around to the printing linofwhen the form is first entered into the carriage. If the form is part of a continuous strip, the automatic ejection device may be set to provide the same head spacing on all forms after the first form.
  • Another object of the invention is to provide an veject mechanism which starts and finishes the ejecting stroke with a slow motion.
  • the device is constructed so that the ejecting may occur at any point along the form and forany number of line spaces with the same type of feeding motion.
  • the record sheet starts from rest and is gradually accelerated'to the mid-point of the feeding cycle, and then during the second half of the feeding operation the sheet is gradually brought back to rest.
  • a feature of the invention is the automatic disabling of the detent cooperating with the platen line spacing shaft on the carriage during ejection. This eleminatesv the noise which would otherwise attend ejection.
  • Another object of the invention is to provide "means for increasing the power of the carriage motor during ejection. This is done byautomatically cutting out a resistance which is placed in series with the motor during operation inline The eject and line spacing devices are eontrolled by the presence of record cards in the tabulator. At the end of a run of cards the operating connections to the paper feeding mechanisms are disabled until other cards are analyzed.
  • Another feature of the invention is the provision of means to stop the tabulating machine. during the operation of the ejecting mechanism when .this mechanism is set to eject after every item and for ejection at the end of a form. This is done to give the paper feeding devices time to function betweentheprinting operations of the regular tabulating machine. Devices are provided to delay the restarting of the tabulator until the eject mechanism is back in normal position.
  • Another object of the invention is to provide devices for controlling ejecting after the printing of a minor or major total. These group control devices serve to prevent line, spacing operations on occurrence of totals in listing and tabulating operation. They also serve to prevent stopping of the'tabulator and ejection when a total is to be printed below the printing end of a form.
