Abstract

A pen nib construction comprising a pen nib and a holder in which the pen nib is fitted. The pen nib is constructed by a plurality of pen nib pieces fixed back-to-back to each other and forming an ink channel extending axially, and the pen nib is provided at its pointed end with long splits and relatively short recesses 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 a plurality of ink feed tongues which are in contact with the outer surface of the pen nib. The other end of the holder is connected to an ink reservoir of the pen. At least one of the pen nib pieces is provided on its intermediate portion with another split which connects the ink channel with outside of the pen nib. Thus, ink is supplied from the ink reservoir to the pointed end of the pen nib through a plurality of passages including the ink channel and the narrow gap between the pen nib and the ink feed tongues. The feeding of ink through the ink channel or the narrow gap is carried out by capillarity action taking place at their portion. From the pointed end of the pen nib, ink flows out through the splits and the recesses onto the paper.
