Improvements in Fountain-pens.
I, MORRIS WOODBURY MOORE, of 288, Maple Street, 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 :-
This invention in self-feeding fountain pens particularly relates to the devices for
regulating the flow of ink from the barrel or ink reservoir to the pen; and the
invention consists in the combination with the pen barrel provided with a tip having
a passage longitudinally therethrough of a feed bar in said passage and extended
into the chamber of the barrel and also forwardly to the pen having a longitudinal
groove and a valve consisting of a collar encircling and movable on said bar and
provided with a tongue which fits within said feed bar groove, all substantially as
will hereinafter more fully appear.
In the drawing the present improvements in fountain pens are illustrated:
Figure 1 being an enlarged longitudinal sectional view of the fountain pen taken
through the back of the writing pen ;
Figure 2 is a cross section taken on the line 2-2, Figure 1, and
Figure 3 is a cross section taken on a line 3-3 of Figure 1.
In the drawings, A represents the barrel and reservoir of the pen, usually con-
structed of hard rubber the upper. end of which is closed; and its opposite end is
also closed by the tip, B, which screws thereinto being removable for the purpose
of filling the reservoir with ink, and to permit of the adjustment of the valve as
below described.
The tip is provided longitudinally thereof with a passage, a, which leads from
end to end thereof, the outer extremity of the tip being chambered for the insertion
of the pen, b, and the spring bushing, d, of cylindrical form, for retaining the pen
by its shank in place in said chambered tip extremity.
The feed bar, D, is longer than said tip and extends through and closely fits and
practically fills the longitudinal passage therein, its forward end extending to and
upon the under side of the pen near its point, while the rear end is projected above
the tip into the reservoir.
The feed bar is grooved from above the place of its entrance into said passage
through the tip, the said groove, f, extending along the tip to the under side of the
pen, being open to the forward end of the feed bar.
Upon said feed-bar above the inner end of the tip is a valve, which consists of a
collar, g, adapted to encircle and slide on the bar internally provided with a tongue
or rib, h, which fits the said feed-bar groove, forming as it were a gate or partition
therein.
It is apparent that if the said collar is slid down against the upper end of the tip
there can be no ink flow from the reservoir down the feed-bar groove through the
tip to the pen, while the further the internally ribbed collar is slid away from the
end of the tip, the greater will be the freedom of ink flow, the copiousness of such
flow being very nicely regulated according to the requirements of the writer.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. In a fountain pen the combination with the reservoir-barrel provided with a
tip having the writing pen therein and with the longitudinal passage through same,
of a food her preatically filling said massage and extended into the reservoir above

page_text: the tip and also forward to a contact on the pen, having the longitudinal groove and
valve consisting of a collar encircling and movable on said feed-bar and provided
with a tongue which fits within said feed-bar groove, substantially as and for the
purpose set forth.
2. A. feeder for a fountain pen consisting of a bar having a groove therein and
running longitudinally thereof to its forward end, and a collar encircling and
movable on the bar and provided with the tongue which fits said groove, substantially
as described.
