7 Claims.
This invention relates to new and useful im
provements in fountain pens and more particu
‘larlyl ity pertains to fountain pens of the type
which employ more than one color of ink and
which are capable of writing at will with any of
the particular colors of ink.
It is an object of the invention to provide a
fountain pen in which at least two different colors
of ink may be employed and in which either color
it may be used independently ofthe other color.
A further object of the invention resides in a
`new ‘and novel construction and arrangement of
parts whereby the inks are maintained separately
at all times with no possibility of their inter
mingling.
Still a further object of the invention resides
in a novelconstruction of filling means whereby
, the ink reservoir may be independently filled by
a mechanism which may be independently con
nected with each reservoir for operation.
With the above and other objects in view, ref
erence is had to the accompanying drawing,
wherein;
‘
‘
upper end of each of these tubes is flared as at
25. The purpose of this construction will be
hereinafter described.
Carried by the forward end of the tube ll”,
there is a semi-circular tubular member 22'., and 10
carried by the forward end of the tube it, there
is a similar member 23.
These members are
spaced with respect to each other, as illustrated
in Figure el, and as best illustrated in said figure,
the tubular members l'l and lß are of such diam
eter as to form a tight friction fit between th
curved wall and the straight wall of their re
spective forward tubular member 22 or 25 where
they are engaged therewith. This construction
provides spaces 2B upon opposite sides of the t 20
tubular members El and i8 through which the
ink may flow from the reservoirs l2 and i3 into
the forward tubular members 22 and 2s, respec
f

assembled position, the tubular member il' will
be substantially in line with the passage E5 and
the tubular member i8 will be substantially in
line with the passage it of the wall ifi, and the

"40 .enlarged scale illustrating the method in which
the pen points or nibs are operated in order to
be moved to either of their operative positions,
and;
Figure 8 is a distended perspective view with
a portion of the barrel broken away.
Referring more particularly to the drawing,
the pen comprises-a barrel section lil, which bar
rel section til is divided longitudinally by a par~
tit-ion Il to form two ink reservoirs l2 and i3.
i550 The rear end of the barrel section is closed by
a wall it which has two passages l5 and l5 there~
through. The forward end of the barrel it! is
closed by a wall i9, and passing therethrough
@there are two tubular members Il and i8 which
extend toa point closely adjacent the rear wall
tively.'
`
As best illustrated in Figure 2, the tubular
members Vi and lil terminate at a point short of
the forward end of their respective tubular mem"
bers 22 and 23, as illustrated at Edin Figure 2,
and this construction provides a relatively small
space 2l between the ends of the tubular mem- a 30
bers ll' and i8 and the forward ends of their
respective tubular members 22 and 23.
Carried by the tubular extensions `22 and 23,
there is a sleeve member 3G, best illustrated in
Figures 6 and 8. This sleeve member is cut out i
as at 3i and 32 to provide leg extensions 33 which
are spaced from each other. This sleeve is of
such a diameter that‘it has a friction ñt with
the tubular members 22 and 23, which friction
fit will be sufficient to retain it in either of the ‘.4
adjusted positions to which it is moved and which
will be hereinafter described.
The writing nibs or points are designated ¿it
and 60’ and they are carried by a block 4I,
which block ¿ll has two angularly disposed pas- .
sages ¿i2 and 43 which lead respectively to the
feed bars ¿it and‘tä of the writing nibs or points
4U and 49’. Each of these passages ¿l2 and 43
terminates in a nipple éiß, and these nipples lili
are adapted to be received in openings ¿il in the- 50
inner flat faces ¿i8 of the leg extensions 22 and
23, this construction being shown in Figure 8.
The marginal edges of the openings dl are
flanged, as best illustrated at 49 in Figure 6, and
the nipples 46, heretofore mentioned, cooperating 1 55
2
2,130,774
with the flanged edge of their respective open
ing 4`I form a liquid tight joint between the
block 4I and the tubular leg extensions 22 and
23, thus assuring that there is no leakage of ink
at this point. In addition to providing a liquid
tight joint, the construction just described pro
vides for pivotally mounting the block 4I be
tween the leg extensions 22 and 23 in order that
the same may be rotated between the legs to
move the writing nibs or points into and out of
operative writing position, as illustrated by
dotted and full line positions in Figure 7 of the
drawing.
With the parts in the position in which they
15 are shown in Figure 2, ink will feed from the
reservoir I3 to the tubular leg 23, from which it
will pass through the passage V43 to the feed‘bar
45 of the writing nib or point 40’. If, however,
the block 4I be rotated through 180°, the feed
20 bar 44 would then be moved to the forward posi
.tion and the ink would feed from the reservoir
I2 to the tubular leg extension 22 through the
passage 42 to the feed bar 44 of the other writ
ing nib or point 40.
25
The reference numeral 50 designates a bolt
which is threaded as at 5| into a bushing car
ried-by the rear wall I4 and rotatably mounted
upon this bolt 50 there is a disk like member 52
which has a passage 53 therein. This passage
-30 53 is adapted to be brought into registration with
either of the passages I5 and I6 for a purpose to
be now described. The member 52 has an ex
tension 54 which carries a compressible sack 55
which is adapted when collapsed and' allowed to
-35 refill, to draw ink into either of the reservo-irs
I2 or I3 as the case may be. With the parts in
the position in which they are shown in Figure
2, if the feed bar 45 be submerged in a recep
tacle of ink and the sack 55 collapsed, air will
40 be forced from the sack 55 through the passages
53 and I6, the reservoir I3, tubular member I8,
passage 43, and in this manner discharged from
the pen. Upon release of the collapsible sack
55, ink will be drawn in through the feed bar,
45 passage 43, and into the tubular leg extension
23. A few such operations will completely ñll
the reservoir with ink, after which the member
52 is rotated so `that its passage 53 will be out
of registration with the passage 5I. Registra
50 tion of the passage 53 with the passage I5 and
operation as just described will ñll the reservoir
I2 with ink which obviously, would be of a dif
ferent color. The member 52 may befprovided
with suitable indicating means in the form of a
55 notch 58 adapted to register with notches 59
upon the extension 6I) of the barrel Il] in order
to indicate the proper position of the member 52
to have its passage 53 register with either the
passage I5 or I6. A suitable cap 6I may have
60 threaded engagement with the barrel III as at
62 to enclose the collapsible member when the
same'is not in use, and a reversible cap 63 which
carries the conventional pocket clip 54 is >adapted
for threaded engagement as at 65 of the barrel
65 IIJ in order to enclose the writing end of the pen
when not in use.
In order to rotate the block 4I through 180°
as heretofore described, the sleeve member 38,
heretofore mentioned, must be turned until the
70 spaces 3I and 32 coincide with the space be
tween the tubular leg extensions 22 and 23, in
which position the block 4I is free to move
through the spaces between the legs of the sleeve
and the tubular members 22 and 23. After the
75 blockrhas been rotated to the desired position to
expose either of the writing nibs or points. the
sleeve 30 is again rotated so that its extensions
3I and 33 will cover or enclose the open spaces
between the tubular extensions 22 and 23, as
best illustrated in Figures 4 and 5, in which po
sition the block 4I will be held against movement
about its pivotal points, and the pen exposed for
writing will be rigidly held in writing position.
In order to retain the member 52 tightly upon
the wall I4, a washer 'ED and a spring 'II may
be interposed between the head 12 of the bolt
5|] and the upper face of the member 52. The
bolt 5i) being anchored in the wall I4, and the
spring ‘II being under compression, a tight work
ing ñt between the member 52 and the wall I4
will be had.
From the foregoing it will be apparent that the
present invention provides a new and improved
fountain pen in which at least two colors of
writing ñuid may be employed and in which the
choice of writing fluids may be made at will.
While the invention has been herein illus
trated in its preferred form, it is understood
that it is not to be limited to the specific de
tails of construction herein shown and >that it
may be practiced in other forms which right
fully fall within the scope of the appended
claims.
