Improvements in Fountain Pens.
I, JOSEPH EDWIN CHASE, of Number 37 Fairfield Avenue, in the City of
Holyoke, in the County of Hampden, and State of Massachusetts, United States
of America, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:—
The object of this invention is to so improve the construction of fountain pens
that the pen may be carried in the pocket without liability of leakage, a
characteristic of the pen to which these improvements pertain being that the
writing pen is longitudinally movable to be projected beyond, or withdrawn
within, the lower end of the tip section.
The invention consists in constructions and combinations of parts substantially
as will hereinafter fully appear and be covered by the claims.
The improvements are illustrated in the accompanying drawings, in which
Figure 1 is a longitudinal section through the improved pen.
Figure is a perspective view showing the writing-pen and the retracting rod
therefor.
Figures 3 and 4 are cross-sections, respectively, ou the lines 3-3, and 4-4, of
Figure 1, and
Figure 5 is a sectional view centrally and longitudinally through the upper
portion of the aforesaid rod.
In the drawings, A represents the barrel or reservoir having the tip
section, B, connected at its lower end by the screw-thread joint, in the usual
manner. The lower portion of this tip section has longitudinally through it an
opening, a, of a transverse contour, substantially as seen in Figure 4 in which
the pen, a, is fitted for a somewhat close, though free, longitudinal sliding
movement.
The retracting rod, d, which is longitudinally extended within the barrel and also
downwardly extended through the greater portion of the length of the tip section
has a connection, in any suitable manner, with the upper end of the pen, and this
rod extends with an ink-tight fit through an opening therefor in the upper end of
the barrel.
As shown, and preferably constructed, the forward end of the rod is split to
embrace the shank of the pen, the engagement being rendered more positive by the
rivet, f, and the rod has its portion at one side of the split forwardly extended, as
seen at d, through and beyond the lower extremity of the tip section to lie against
the underside of the pen at the middle line thereof. The tip section has the
opening, a, widened, as at c,-again see Figure 4,-to accommodate this extension of
the rod.
A suitable duct is furthermore provided to lead down to the tip section for the
conveyance of ink from the reservoir to the pen. The form of duct here indicated
at g, being efficient for this purpose.
The upper end of the rod, in its passage through the upper end of the barrel, is
preferably packed by the provision thereat of a sleeve, of soft rubber or equivalent
compressible material.
As shown, the barrel has in its upper end the axial opening, h, with the
peripheral depression, i, while the sleeve, j, of soft rubber has the external
circumferential bead, k, which sinks into the said depression and prevents, as the
rod is moved, end wise displacement of the sleeve by reason of the friction caused
by the constrictive contact which it has against the aforesaid rod, d.

page_text: The cap, m, is fitted upon the upper end of the reservoir to close
conceal the pen-retracting-rod and to serve as an additional safe-guard against any
possible oozing or leakage of ink thereat, and the cap, n, is adapted to be removably
fitted upon the lower end of the tip section when the pen is retracted within such
end. To permit the retraction of the pen, the cap, m, is removed and the rod
upwardly drawn when the said cap is replaced, and at this time the cap, n, is placed
upon the end of the tip section when the pen may be safely carried in the pocket
without danger of leakage.
The user, in taking the pen from his pocket, after removing the cap, n, and
placing it upon the cap, m, draws the latter from the upper end of the barrel and
forces through the rod, d, the pen, downwardly, in readiness for writing when said
cap, m, (with the cap, n, thereon) is placed upon the upper end of the barrel.
To fill the reservoir the rod is held by its upper end and the tip section unscrewed
free from the barrel, when it may be slid off over the lower end of the rod and pen.
It will, however, be perceived that the rod, as indicated in Figure 5, is formed by
screw-united sections; and, therefore, by turning the tip section and with it the pen
and lower section of the rod,-holding the upper section of the rod against turning,
the tip, on being removed from the barrel may carry with it also the pen and said
lower section of the retracting-rod,-a reversal of these movements of course being
required for the re-establishment of the conditions to use the pen.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A fountain pen having a barrel or reservoir provided with an opening in its
upper end, a longitudinally movable rod located in said barrel having one end
extending through the opening in the upper end of the barrel, and a pen secured to
the rod at its other end, a tip-section secured to the barrel and provided with a
longitudinal passage constituting a way for the movement of the pen in and out of
said sections and a groove for the passage of the ink, a removable cap on the upper
end of the reservoir having an opening for the reception of the rod, and another
cap to close the lower end of the tip-section and adapted to fit on the upper cap, all
substantially as described.
2. In a fountain pen, the combination with the reservoir or barrel having in its
forward end the tip with the pen end wise movable therein, and with a suitable ink-
way leading from the reservoir to the pen, of a rod located within the reservoir and
having one end formed split to embrace the upper end of the pen and having the
uniting rivet and the rod having an extension downwardly under the pen, and said
rod having its upper end projected through a suitably packed opening therefor i
the upper end of the barrel, substantially as described.
3. In a fountain pen, the combination with the barrel or reservoir having in it
upper end a circular opening with a peripheral depression, the annular packing o
soft rubber having an external circumferential bead and the rod movable throug
the packing, substantially as and for the purpose set forth.
