  • This invention relates :to the reception of messages by telephone, particularly messages in "Written form when the party called 'is
  • An object of the invention is to provide: an arrangement'of apparatus and circuits which canbe utilized in combinationwith ordinary telephone circuits and instruments to enable the party calling to ascertain, firstthat the v message to be written down at the place party called is'not present at the opposite end or the line; and then by the'manipulation in a predetermined manner of the well-known dial for automatic telephones, to cause the called, to be kept till the party called returns. It is accordingly characteristic of this invention, that, after a normal connection is obtained, the mechanism of this apparatus, which may'beworked either mechanically or.
