1 Claim. (Cl. 1Z0-49)
This invention relates to fountain pens and it
consists in the constructions, arrangements and
combinations herein described and claimed.
More particularly, it is an object of the inven
tion to provide a fountain pen wherein-the pen -
to fit -flush with the opening I6; and upon the
inner face of the cap a raised part 22 is formed
of dimensions so as to engage within the opening
I6. In order that the cap 2U may be held in
releasable closed position, a leaf spring 23 is ñxed
to the cap and extended rearwardly a distance
whereit terminates Yin a recurved nib 24 which
has bearing contact with the housing I0. As
here shown, the spring 23 has a portion 23’ em
