Definitions

  • the present invention relates to attachments for typewriting machines, particularly adapted to facilitate the rapid and accurate locating of forms for instance of an individual account sheet over a ledger sheet and over a record sheet placed on the platen of the paper carriage in such a position that simultaneously entries may bel written on three forms.
  • One object of the invention is to provide a contrivance for a type writing machine which will enable one or more forms to be quickly and accurately and individually positioned above the record sheet fastened on the platen in such a manner that the lines of all the superposed forms on which the entry is to be written are exactly in line one above the other.
  • a further object of the invention consists in the provision of a device of the lsaid type which allows the partial replacement of the forms and the recollation of the same in a speedy manner.
