Improvements in Fountain Pens.
I, JAMES YATE JOHNSON, of 47, Lincoln's Inn Fields, in the County of London,
Gentleman, do hereby declare the nature of this invention (which has been
cominunicated to me from abroad by the Eagle Pencil Company, of 73, Franklin
Street, City and State of New York, in the United States of America) 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 improved construction of fountain pens which I
will describe with reference to the accompanying drawings in which Figure 1 is a
longitudinal section of a pen made in accordance with this invention, and
Figure 2 shews the ink reservoir removed from the handle.
Figures 3 to 6 inclusive illustrate modifications, Figure 3 being a longitudinal
section, Figure 4 an elevation of the ink reservoir detached. Figure 5 a detached
view of the removeable head carried by the reservoir and the leader" or ink
conducting strip associated therewith and Figure 6 a detail section on an enlarged
scale of the removeable head and part of the sheath, or pen handle.
Referring to Figures 1 and 2:
A is a tubular sheath, or pen-handle, which may be made of any suitable
At its front end it has an open-
material but is preferably made of hard rubber.
ing b, of a shape and size to receive the feeder plug B which may be of any
preferred construction. This feeder plug conducts the ink from the ink reservoir
to the pen C in the usual way, the pen being inserted and held between the
feeder plug B and the front end of the handle A.
The ink reservoir is shewn at D. It is made of any suitable material, prefer-
ably hard rubber, and is carried by, and is moveable with the plug E, which is
detachably secured to the rear end of the handle. The reservoir D) is formed of a
tube open at its front end and joined at its rear end to the plug, E. It is preferred
to make the reservoir. D and the plug E in one piece, as shewn, and to make the
plug screw into the rear end of the tubular handle A. The length of the reservoir D
is such that when the plug E is screwed home in the handle, the open front end
of the reservoir will press tightly against a seat a formed for it within the front end
of the handle, around the opening 6 therein, so as to tightly close the joint between
the front end of the reservoir and the handle, and thus prevent leakage of ink
from the reservoir into the interior of the handle A. To more effectually secure
this result the seat a is formed around a tubular neck c within the handle, which,
when the front end of the reservoir is forced home to its seat a, enters the front end,
or mouth, of the reservoir, and forms a stopper therefor. Under these conditions
the only passage for the ink from the reservoir to the outside is through the central
longitudinal opening in the stopper c (which is a part of the opening b) where it
meets the feeder plug B, and by it is conducted to the pen.
The construction described is simple, efficient and inexpensive. The reservoir for
filling purposes is removed from the rear of the pen; and there is no joint at the front

page_text: end of the handle, through which ink can leak out and soil the fingers, as frequently
happens, when the joint between the plug which carries the reservoir and the handle,
is at, or near, the front end of the latter.
The pen is provided with the usual removeable cap, or covering sleeve, F, which
may be fitted upon its front, or rear end, as occasion demands.
In the modification shewn in Figures 3 to 6, the neck c is dispensed with, and
a valve-like head I, is employed to fit against a seat in the handle so as to close all
communication between the ink reservoir and the pen when occasion demands.
G is the tubular sheath having an opening 9, at its front end, for the reception
of the pen nib C and the feeder plug B. Within the sheath is a shoulder H,
preferably bevelled as shewn at h, which forms the seat for the valve-like head I.
K is the ink reservoir, having at its rear end the plug E, which screws into the
rear end of the sheath.
Fitting the front end of the ink reservoir is a valve-like head I, which is prefer-
ably removeable from the reservoir to permit the latter to be filled more readily.
It has an unperforated front end, or top, adapted to fit against the seat H; and
it is perforated at i to permit ink to pass out therethrough from the ink reservoir.
A "leader," or ink conductor, J, may be arranged within the ink reservoir,
consisting of a strip of material, such as hard rubber, having one end j bent into
U-shape and adapted to fit into, and (by reason of its resiliency) to engage with, the
head I, so that it can be removed from, and replaced in, the ink reservoir along
with the head.
When the plug E is screwed home, the head I, will be forced against the seat H,
and will act as a valve, or stopper, to close all communication between the ink
reservoir and the opening g in the pen handle. By slightly unscrewing the plug E,
the reservoir and consequently the valve will be sufficiently retracted to permit
ink to flow from the reservoir through the openings i to the pen.
'
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. In fountain pens the combination with the handle and the feeder, of the plug
closing and removeable from the end of the handle, the ink reservoir carried by
the said plug, and a seat, or shoulder, within the front end of the handle, against
which the front end of the reservoir, or a head carried by the reservoir, will bear
when the plug is screwed home, as, and for the purposes, herein before set forth.
2. In fountain pens the tubular handle formed at its front end with a seat, and a
neck c, in combination with the removeable plug closing the rear end of the handle,
and the ink reservoir carried by the said plug, and fitting at its front end,
around the neck c, and against the seat, as hereinbefore described and illustrated
in Figures 1 and 2 of the accompanying drawings.
3. In fountain pens the combination of the tubular handle, the plug closing,
and removeable from, the rear end of the handle, the ink reservoir carried by
the said plug, and the removeable head carried by the said reservoir
provided with openings for the passage of ink, and with an unperforated
portion adapted, when the plug is screwed home, to fit closely against a seat
within the handle so as to close the opening in the front end of the latter through
which ink passes to the nib of the pen, substantially as herein before described and
illustrated in Figures 3 to 6 inclusive of the accompanying drawings.
