Beauford Harold Dicks, Athelstane, Wis.
Application December 29, 1937, Serial No. 182,347
3 Claims. (Cl. 1Z0-48)
This invention relates to fountain pens >and has
for an object to provide a fountain pen having a
replaceable ink tube and valve. therefor to pro
mote an easier and cleaner refilling of a fountain
pen with ink than hitherto possible.
A further object is to provide a fountain pen
having a novel ink tube which may be easily
inserted in and removed from the fountain pen
barrel and which will carry as a unit therewith a

The collar is provided with a bayonet slot I9, 25
best shown in Figure 9, to receive a guide pin 20
carried by the cap. Manual rotation of the cap
turns the ink tube Ill on its axis.

With the above and other objects in view the
invention consists of certain novel details of con
struction and combinations of parts hereinafter
fully described and claimed, it being understood
30 that Various modifications may be resorted to
within the scope of the appended claims without
departing from the spirit or sacriñcing any of
the advantages of the invention.

Referring now to the drawing in which like
characters of reference designate similar parts
in the various views, I0 designates the fountain
pen barrel, II the sleeve, I2 the clip, and I3 the
V11:0 valve adapted to be held stationary by certain
`parts of the fountain pen while other parts of
the fountain pen, namely, the cap on the end
of the barrel, may be rotated to turn .the tube

ink tube and valve assembly.
Figure 5 is a detail cross sectional View taken on

the ink tube, opposite the wrench head I5 is pro
vided with a port 22. The cylindrical wall of the
tube near the port is provided with a cir
cumferential groove 23. A substantially cylin
drical valve 24 is assembled as a unit with the
grooved end of the ink tube and for this purpose
a rib 25 is spun or otherwise formed in the valve
to rotatably nest in the groove 23. The valve is
provided with a diaphragm 26 having a port 21,
best shown in Figure 8, adapted to be brought into
registration with the port 22 in the end wall of
the ink tube to permit the contents of the ink
tube to escape. Beyond the diaphragm the valve
is provided with a squared wrench head 28, best
shown in Figure 6.
The wrench head 28 is for the purpose of hold
ing the valve stationary while the ink tube is
turned on its> axis to dispose the ports 22 Iand
21 selectively in registration or out of registra
tion. The part of the pen which holds the valve
stationary is the nib 29, the same having a 50
squared socket 3D, best shown in Figure 4, to re
ceive the wrench head 28 of the valve. A washer
3| is interposed between the end of the wrench
head 28 and the end wall of the squared socket.
as best shown in Figure 2.

The nib 2s is provided with a guide pin 32
which is engaged in a longitudinal slot 33 formed
in the bore of the barrel l0. The pin prevents
rotation of the nib and permits application and
removal of the nib from the barrel by straight
line movement.
A ferrule 34 is threadedly engaged with a re
duced neck on the barrel as shown at 35. The
ferrule is provided with a shoulder 36 which is
10 adapted to clamp the collar 3T on the nib_29,
against the end of the threaded neck of the bar
rel and hold the nib firmly in position.
the construction and operation of the invention
will be fully understood without further explana
tion.
What is claimed is:
l. A fountain pen comprising a barrel, a tube
ñlled with ink removably disposed in the barrel,
a valve on one end of the tube, a wrench head
on the opposite end of the tube, means connected
with the barrel and disposing the valve in a pre
determined relationship with respect to the
wrench head, and a cap removably and rotatably
disposed on the barrel and having a socket receiv
By referring to Figures 1 and 9 it will be seen Y ing said wrench head for rotating the tube with
that legends are formed on the barrel to denote respect to the valve to open and close the valve.
2. A fountain pen comprising a barrel, a tube 15
15 “On” and “Off” positions of the valve, these
legends being provided with suitable indicating containing an ink supply removably disposed in
arrowheads which coact with a single arrowhead
the barrel, a valve on one end of the tube, a
on the cap ll in indicating said positions. To
replace an empty ink tube and valve assembly
20 when the tube has been used up, the cap I1 is
turned until the indicating arrow thereon ar
rives at the legend “Remove”, At such point the
wrench head on the opposite end of the tube, a
wrench head on said valve, means connected to
the barrel and engaging the valve wrench head 20
pin 20 is in registration with the longitudinal leg
for holding the valve stationary, and a cap re
movably and rotatably disposed on the barrel and
having a socket receiving the wrench head of the
38 of the bayonet slot so that the cap may be re
tube for rotating the tube axially with respect to
moved. Thereupon, the projecting end of the ink
tube may be clasped in the lingers and the tube
and valve assembly withdrawn endwise from the
barrel. The empty ink tube may be discarded and
a full ink tube and valve assembly thereupon in
30 serted endwise in the barrel until the wrench
head 28 of the valve engages in the squared socket
30 in the nib 29. The cap l1 will now be slipped
the valve to open and close the valve.

3. A fountain pen comprising a barrel, a cap on
one end of the barrel, a bayonet joint connection
between the cap and the barrel whereby the cap
may be rotated on the barrel, a tube containing
a supply of ink housed in the barrel, a wrench 30
head on the tube detachably engaged with said
on to the collar I8 and given a suilicient turn to
bring the indicating arrow of the cap at the
cap whereby turning of the cap turns the tube
axially, a nib on the other end of the tube, a pin
and slot connection between the nib and barrel
legend marking “Off”. VTo permit the ink to
permitting of the nib being assembled by endwise 35
escape from the tube to the ink feeder 39 and
pen point 40 the cap need only be rotated until
the pin arrives at the end of the bayonet slot in
which position the arrowhead of the cap will be
40 in registration with the legend “On” and the valve
Will be open.
From the above description it is thought that
movement with the barrel, a valve carried as an
integral assembly with the tube, a wrench head
on the barrel, and a socket on the nib removably
engaging the valve wrench head for holding the
valve stationary to permit control of the valve
by rotation axially of the ink tube.
