ABSTRACT:
A nib holder for a fine molded nib in a writing instrument is disclosed. The nib holder has an internal passageway into which the nib may be inserted and held by an abrasive ring or by projections, the nib being held without substantial deformation thereof. The nib holder includes a screw threaded portion which cooperates with mating screw threads on the casing of the writing implement. The nib holder may be screwed into the casing until the end of the nib contacts a fixed ink conducting core. Therefore, as the nib holder is screwed into the casing, the nib is forced out of the passage in the holder for compensating for wear of the nib. A cooperating prong and detent on the casing and nib holder control the rotation of the nib holder with respect to the casing.
