page_text: We, NOYES FINK PALMER, Engineer, of Jamaica, Queens County, State of New
York, and PAUL ERNEST RICHTER, Merchant, of the city of New York, County and
State of New York, United States of America, 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 relates to an improvement in fountain pens, whereby a double feed,
one at bottom and one at top of pen, is obtained.
This invention relates to the various features of improvement hereinafter more fully
described.
In the accompanying drawing;
Fig. 1 is a vertical longitudinal section of a fountain pen with our improvement.
Fig. 2 is a side view of the same.
Fig. 3 is a longitudinal section of the bottom feed block.
Fig. 4 is a top view of the same.
Fig. 5 is a cross section of the same at line a, a, fig. 3.
Fig. 6 is a top view of the pen plug.
Fig. 7 is a bottom view of pen plug, pen and bottom feed.
Fig. 8 is a top view of the
pen plug with pen in place.
Fig. 9 is a cross section at line 2, , fig. 8.
Figs. 10, 11 and 12 show longitudinal section, top view, and cross section of
modifications of the bottom feed block.
The letter A represents the usual hollow handle or reservoir to contain the ink
provided at its closed end with the usual nipple a, to receive the cap piece B, when
the pen is in use.
The opening at the other end of the handle is threaded to receive
the hollow upper feed and pen plug C.
This plug receives the gold or other pen P and is provided in its inner cavity with
a small shoulder s for the end of the pen to bear against.
By this arrangement the pen after having been removed will always find its exact
position when again replaced into the plug.

page_text: This plug C is provided with a long narrow extension tongue d, laying on the top
and projecting some distance over the slit of the pen.
Into the central hollow part of this plug C the lower feed plug E is inserted. The
end of this feed plug fits tightly into the central opening of the plug Cand is
provided with a central cavity and a small channel h on top connecting with the
interior of the reservoir A.
This channel connects through an opening i with the central cavity and a
corresponding opening leads from this central cavity downwards and connects
therewith a channel I extending from this opening k to the end of the feed plug C.
From the circular end of this lower feed plug E extends a projection and tongue e
fitting against the inside of the pen, as close as possible, while the outer side of this
tongue e is tapered off, and is extended nearly to the point of the pen.
On the inside of this tongue e, or the side nearest the pen, a channel
extending nearly to the extreme point of the tongue, and connected with channel h
on top of the plug, see fig. 4.
In figs. 10, 11 & 12 the bottom feed block has no
end is provided with two channels h, h, of which
the channel connects with a channel or opening
The operation is as follows:
is made
central opening and the top of its
connects with the channel n and
for the admission of air.
The hollow handle or reservoir A is filled with ink, the upper feed plug C screwed
into the threaded open end, and the central plug E inserted into this plug C, when
the pen P is inserted between the plugs C and E, till it bears against the shoulders,
when the pen will be ready for operation, regulated automatically by the flow of ink
and air, in all cases, whether fine lines or broad heavy lines are to be made.
When the pen is pressed upon the paper, capillary attraction and gravity draws
the ink from the handle or reservoir according to the opening of the nibs of
the pen.
Air flows then through the openings k and i to the channel h freely, when the
nibs of the pen are spread far apart for very heavy lines or writing, while when
the pen nibs are but slightly opened, the air will flow only slowly. In other
words the flow of air will be directly in proportion with the opening of the nibs
of the pen.
If this would not be so the ink would flow entirely from the hollow handle
whenever the position of the pen was with its point downward.
The ink laying in the channel n in the tongue e close to the point of the pen, on the
under side, allows a ready starting and after starting and during heavy line making
and shading, the ink flow is maintained by the top tongue extension d of the upper
feed. The ink passing from the channel n, into the lower tongue, through the slit in
the pen, into the cavity formed between the top of the pen and the under-side of the
tongue d, said tongue being slightly bent upwards by the bending of the pen during
the operation of writing.
It is well known to those skilled in adjusting this class of pens that only a bottom
feed is very troublesome and insufficient in heavy writing, for the reason that the
pressure upon the pen and the consequent bending of the same upwards leaves
the bottom feed channel inoperative, without giving the feed too much vent for the
ordinary fine line writing.
The combination of a bottom feed with a top feed entirely relieves this trouble.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is ;
1. In a fountain pen the combination of the handle or reservoir A, pen plug C,
pen P, and central plug E, with a projection or tongue d attached to the pen plug C,
and laying upon the pen over the slit and a projection or tongue e laying against the
under side of the pen, and extending nearly to the point of the pen, substantially as
specified.
2. In a fountain pen, the combination of the pen plug C, with the hollow central
feed plug E, provided with a central longitudinal cavity g, and channels h and / and

page_text: with opening i connecting the cavity g with the channel h and opening connecting
the cavity g with the channel operating in combination with the pen and ink in the
reservoir in the manner substantially as set forth.
3. The combination of pen plug U with tongue d, with the feed plug E, provided
with tongue e, cavity g, opening and channel and channel on the face of the
tongue e and forming a continuation of the channel n substantially as described.
4. In combination with the pen plug C and pen P, the shoulders, in the inside of
the plug C, as and for the purpose specified.
5. In a fountain pen, the combination of a pen, with a top feed consisting of a
tongue attached to the pen plug, and laying upon the pen, over the slit, and a bottom
feed consisting of a tongue attached to central hollow feed plug and extending nearly
to the point of the pen and provided with an ink channel connected to the central
cavity of the plug and to a channel on top of said plug substantially as and for the
purpose specified.
6. In combination with a hollow central feed plug E, of a fountain pen provided
with a forward extending tongue e, and with a central cavity g and top channel h
connected with the ink reservoir, the opening and channel Z connected with the outer
end of pen plug C substantially as and for the purpose set forth.
7. The combination in a fountain pen, of a top feed extending over the top of the
slit of the pen, with a bottom feed plug, provided with an ink duct, extending under-
neath the slit of the pen, substantially as described.
