FOUNTAIN PEN
Joseph White, Comstock, N. Y.
Application February 29, 1936, Serial No. 66,465
6 Claims.
The present invention relates to improvements
in fountain pens.
The primary object of the invention is to pro
vide a pen that will contain ink of several differ
;5 ant colors and present novel valve means for
selecting the desired color of ink to be used.
A further object of the invention is the con
struction and arrangement of a rotatable disc
and valve closely associated with the discharge
'10 ends of the ink-carrying reservoirs and pen point,
whereby when one color of ink is selected for
use the other color will be forced back into its
reservoir, thus alleviating any possibility of the
ink becoming mixed.
The invention will be fully and comprehen
sively understood from a consideration of the fol
lowing detailed description when read in connec
tion with the accompanying drawing which forms
part of the application.
In the drawing:
Fig. 1 is a transverse sectional view of the new
and improved pen and illustrating 'in plan the
ink carrying reservoirs.
Fig. 2 is a sectional view taken on line 2—2 of
Fig. 1.
Fig. 3 is a perspective view of the parts forming
the valve means for selecting and controlling the
desired color of ink to be used.
Fig. 4 is a sectional view taken on line 4-4 of
Fig. 1; and
Fig. 5 is a diagrammatic view illustrating the
' movement of the eccentrically mounted valve
with respect to the discharge opening.
Referring to Fig. 1 of the drawing, it will be
noted that the invention comprises a barrel 6
provided with a partition ‘I for dividing the barrel
into- two sections for receiving the collapsible
ink reservoirs 8 and 9. For purposes of illustra
tion, the invention has been disclosed in use with
. :40 two reservoirs, but it is to be understood that any
desired number can be effectively used without
departing from the spirit of the invention.
Each of the reservoirs may be supplied with
ink thru the use of the usual ?lling means in
.45 cluding the pivoted arm I0 engaging with the
longitudinal compressing member II‘. When re
plenishing the supply of ink in each reservoir it
will of course be necessary to control the valve
selecting means to be later described.
Mounted within the barrel 6 and adjacent the
.50
discharge end of the collapsible reservoirs 8 and
9,, is a plug member I2. The ends of said reser
voirs engage upstanding shoulder portions I3 of
the plug member I2 and the ink is fed to the pen
thru the channels I4 and I5 from the reservoirs
(Cl. 120—42)
8 and 9, respectively, the said channels being
formed within the body of the plug member I2.
Positioned adjacent the plug member I2 is the
feeding head I6 _constructed with a recess l1 and
supporting feed troughs I8 and I9 directly con
nected to the channels I4 and I5 of the reservoirs
8 and ,9, respectively. The feed troughs I8 and I9
are supported from shoulder portions depending
from the plug member I2 and upstanding
shoulder portions forming a part of the feeding 10
head.
Centrally disposed within the feeding head I6
and directly connected to said troughs I8 and I9
is the member 20 which aids in supporting the
pen point if and thru which the supply of ink is 15
fed to said pen point. A pair of channels 22 and
23 have communication with the feed troughs I8
and I9 and are controlled by the means illus
trated in Fig. 3 of the drawing. The valve con
trolling means comprises the rotatable disc 2131
provided with recesses 25 and 26 adapted to be
aligned with the feed troughs I8 and I9, respec
tively, depending upon the desired color of ink
to be used. The disc 24 is rotatably mounted
Within the body portion of the member 28 and
is positioned in close proximity to the discharge
ends of the feed troughs I8 and I9, as illustrated
in Fig. l of the drawing. Means for controlling
the rotation of the disc 24 includes the trans
versely disposed rod 21 secured within the up 30
standing portion 28 of the valve disc 24. The rod
27 extends transversely thru the barrel of the
pen and has its opposite end passing thru the end
of the barrel and connected to a knurled nut 29
for controlling the rotation thereof.
The other portion of~ the valve controlling 0
means comprises the cone-shaped valve 30 con
nected to the disc 24 thru the medium of the con
necting rod 3i, the upper end of which is secured
within a recess in the bottom portion of the valve
disc 24 so that said disc 24 and cone valve 38 will
rotate in unison.
Diagonally disposed and at diametrically oppo
site points within the cone-shaped valve 38 are
a pair of channels 32 and 33 adapted to align with 7
the openings 25 and 26, respectively, of the valve
disc 24 vfor controlling the selected color of ink to
be fed to the pen point 2 I. It is to be understood
that the valve disc 24 and valve 36 will rotate in
unison upon turning of the knurled nut 29 so that Z
ink will ?ow from a selected reservoir thru its
respective channel into the feeding head I6 and
thence thru either channel 22 or 23 to the pen
point 2|.

reservoir so as to prevent a mixing of the several
colored inks. This can readily be determined by
referring to Figs. 1 and 5 of the drawing. ‘In Fig.
10 1 the respective channels are open so that a sup
ply of ink will be fed to the pen point 2! from
the ink supplying reservoir 9. During the rota
tion of the rod 21 and its supporting valve disc 24
and cone 36 to select an ink, the ink which nor
15 mally would remain in the channel 35 that has
been fed from the reservoir 8 will be forced back
Wardly and up into the channel 22. It is to be
understood that this action will occur when the
various parts are rotated so that the member 34 a
20 has assumed the position illustrated in Fig. 1.
The converse is“ true if it is desired to supply ink
fromthe reservoir 8. The action of the member
34 can be determined by an inspection of the
illustration in Fig. 5 of the drawing. The center
25 of rotation of the disc 24 and valve 30 is indi
cated by the letter A and the angle of rotation
is con?ned by the radial lines projecting from
the point A. Due to the eccentricity of the mem
ber 34 the center of same will be caused to swing
v30 from the point B to the point C, thereby moving
the opposite side of said member into contact
with the opposite Wall of the recess 35 in which
it is contained, thus‘causing the ink therein to be
squeezed out.
The feeding head MS is provided with the usual
longitudinal thread portion 36 for attaching the
cap Bl for protecting the pen when not in use.

for writing with red ink, the residue in the chan

It is to be understood that this improvement is
capable of extended application and is not con
