Feeder Overlying Tool Patents (Class 401/238)
  • Patent number: 4465391
    Abstract: A pen nib construction comprising a pen nib and a holder in which the pen nib is fitted. The pen nib is provided at its pointed end with long splits and short chinks which are disposed alternately and at equal angular distances. The pen nib contains an ink containing portion near its pointed end. One end of the holder is divided into ink feed tongues which are in contact with the outer surface of the pen nib. At least one of the ink feed tongues is provided on its inner surface with a groove which continues at one end thereof to one of the splits and at the other end thereof to an ink reservoir of the pen. Thus, ink is supplied from the ink reservoir to the ink containing portion mainly or only through the groove and the split, in preference to or instead of through an ink channel which may or may not be provided in the center of the pen nib. From the ink containing portion, ink flows out through the chinks and the splits onto the paper.
