Improvements in Fountain Ink-stands.
I, ALFRED GASKILL, of 4809 Springfield Avenue, Philadelphia, State of
Pennsylvania, United States of America, Confidential Clerk, do hereby declare the
nature of this invention to be as follows:-
A fountain ink-stand is a device in which the ink is raised or otherwise placed in
a small quantity in a part away from the main body of the ink in a separate
receptacle, and in the best forms of such ink-stands, the quantity of ink is small
and readily raised by the insertion of the pen.
In the ink-stands hitherto used of the fountain character, the ink has been raised
into a cup by the pen pressing down a diaphragm or lowering a piston, the conductor
up which the ink flowed has been at the lowest portion of the cup, and the ink,
after the pressure of the pen was released ran immediately back into the ink well.
The chief value of a fountain ink-stand is that it will retain the main body of
the ink away from the air, by which it is evaporated and filled with dust and other.
impurities, and provide a small and constant supply of ink for the pen, apart from
the main body.
The main objection to the fountain ink-stands hitherto has been that when the
upward flow of the ink was caused by the outside pressure and the ink was
permanently maintained in the ink cup by the ink raising devices much trouble
was occasioned in maintaining exactly the right amount of ink in the cup.
If any ink-stands had been made in which the ink was temporarily in a funnel
by other pressure than that caused by the insertion of the pen, they would have
required that the ink raising devices should be operated at each pen dipping and
would have been subject as well to most of the objections to the fountain ink-stands
hitherto made in which the ink is raised by the pressure caused by the insertion of
the pen which, by the fact that the ink runs immediately back into the well when
the pressure ceases, strips off the greater portion of the ink from the pen, which
makes constant dipping and consequently quickly wears out the pen and requires a
conscious effort at each dip to get the ink into the ink cup.
My invention chiefly relates and consists in adding to the ink-conductor through
which the ink flows from the ink well to the ink cup, a receptacle adapted to retain
a small quantity of ink for the use of the pen independently of the devices raising
the ink in the ink conductor.
Fig. 1 is a view of my invented device,
Figs. 2, 3, 4, 5 and 6 are views of other types of my invented device, and
Fig. 7 is a plan view showing how plural ink-conductors may be employed.
On the ink-well constructed in any usual form and of any usual and convenient
material, generally however of glass, I place a diaphragm O, in which I set an ink
cup A provided with a conductor B in the form of a tube which reaches down into
the ink in the ink-well and has its outlet E, which is arranged to throw the ink
horizontally or downwardly into the depressed portion of the ink-well so that it
will not shoot upwards, and fly or go outside the cup by the momentum imparted to
it in its rising in the tube B. This outlet is at the side of the cup A, the whole

being arranged to seal the ink-well C, except through the conductor B. In practice
arrange
the capacity of the portion of the cup A above the level of the outlet E,
so that it will contain without overflowing all the ink which can be raised by a
single depression of the cup and the surrounding parts. After the well has been
filled and the diaphragm and adjacent parts put into place, the ink will be made to
flow into the cup A by the downward pressure of the pen therein in the usual
manner. On removing the pressure the ink above the level of the outlet E will
return to the well. The movement of the cup in a vertical direction is secured by
making it move in a cylindrical constrainer m, the cup being fitted to slide therein.
The action of depressing the cup will be almost unconscious after the lower part of
the cup is once filled and a supply of fresh ink will always be at hand. It will be
however, impossible to overflow the cup.

Figure 1, the ink being retained in a portion of the cup. A' after it has returned
into the well from the portion A³. In this form the downward shoot of the ink
from the ink outlet is not requisite and the ink-conductor may open directly into
the bottom of the portion A. Figure 3 shows a type of my invented device in
which a depressable piston replaces the diaphragm. C is the ink well, and D, the
cover hermetically sealing the same by means of a rubber packing or other suitable
means. The piston is supported by a spring or made light enough to float in the
ink. On this piston is placed the cup A provided with a conductor B constructed
as in Figure 1. I do not limit myself, to this construction as any usual or
convenient form of piston construction may be employed.

one side of a partition by means of a valve H, which opens and closes when the
is depressed and rises respectively.

having a stem extending down through the conductor. This stem may project a
little below the bottom of the conductor so that it will strike against the bottom
of the well before the conductor reaches that point, and consequently lift the
valve slightly, disengaging it if it clogs. Over this valve I sometimes lace a
protector n.
In Figure 6 I have shown a form of my invention in which the ink is forced
into the cup A by pressure exerted exterior thereto. The cup and the conductor B
may be rigidly secured to the well. Communicating with the well is placed the
piston F moving in the cylinder G, by the depression of which the ink is made to
How into the cup A. Upon the release of the piston the ink will flow back through
the conductor B into the well C.

conductor is used to avoid the danger of clogging incident possibly to the use of a

COMPLETE SPECIFICATION.
Improvements in Fountain Ink-stands.
I, ALFRED GASKILL of 4809 Springfield Avenue, Philadelphia, State of
Pennsylvania, United States of America, Confidential Clerk, 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 :-
A. fountain ink-stand is a device in which the ink is raised or otherwise placed in
a small quantity in a part away from the main body of the ink in a separate
receptacle, and in the best forms of such ink-stands, the quantity of ink is small and
readily raised by the insertion of the pen.

page_text: In the ink-stands hitherto used of the fountain character, the ink has been raised
into a cup by the pen pressing down a diaphragm or lowering a piston, the
conductor up which the ink flowed has been at the lowest portion of the cup, and
the ink, after the pressure of the pen was released ran immediately back into the.
ink well.
The chief value of a fountain ink-stand is that it will retain the main body of
the ink away from the air, by which it is evaporated and filled with dust and other
impurities and provide a small and constant supply of ink for the pen, apart
from the main body.
The main objection to the fountain ink-stands hitherto has been that when the
upward flow of the ink was caused by the outside pressure and the ink was.
permanently maintained in the ink cup by the ink raising devices much trouble was.
occasioned in inaintaining exactly the right amount of ink in the cup.
If any ink-stands had been made in which the ink was temporarily in a funnel by
other pressure than that caused by the insertion of the pen, they would have-
required that the ink raising devices should be operated at each pen dipping and
would have been subject as well to most of the objections to the fountain ink-stands
hitherto made in which the ink is raised by the pressure caused by the insertion of
the pen which, by the fact that the ink runs immediately back into the well when
the pressure ceases, strips off the greater portion of the ink from the pen, which
makes constant dipping and consequently quickly wears out the pen and requires a
conscious effort at each dip to get the ink into the ink cup.
My invention chiefly relates and consists in adding to the ink-conductor through,
which the ink flows from the ink well to the ink cup, a receptacle adapted to retain
a small quantity of ink for the use of the pen independently of the devices raising
the ink in the ink conductor.
Referring to the drawings filed with my Provisional Specification,
Fig. 1 is a view of my invented device.
In
Figs. 2, 3, 4, 5 and 6 are views of other types of my invented device and
Figure 7 is a plan view showing how plural ink-conductors may be employed.
On the ink-well constructed in any usual form and of any usual and convenient
material, generally however of glass, I place a diaphragm O, in which I set an ink
cup A provided with a conductor B in the form of a tube which reaches down into.
the ink in the ink-well and has its outlet E, which is arranged to throw the ink
horizontally or downwardly into the depressed portion of the ink-well so that it
will not shoot upwards, and fly or go outside the cup by the momentum imparted.
to it in its rising in the tube B. This outlet is at the side of the cup A, the whole.
being arranged to seal the ink-well C, except through the conductor B.
practice I arrange the capacity of the portion of the cup A above the level of the
outlet E, so that it will contain without overflowing all the ink which can be raised
by a single depression of the cup and the surrounding parts. After.the well has
been filled and the diaphragm and adjacent parts put into place, the ink will be
made to flow into the cup A by the downward pressure of the pen therein in the
usual manner. On removing the pressure the ink above the level of the outlet E
will return to the well. The movement of the cup in a vertical direction is secured
by making it move in a cylindrical constrainer m, the cup being fitted, to slide-
therein. The action of depressing the cup will be almost unconscious after the
lower part of the cup is once filled and a supply of fresh ink will always be
at hand.
It will be however, impossible to overflow the cup.
Figure 2 shows a modified form of ink cup in a construction similar to that in.
Figure 1, the ink being retained in a portion of the cup A after it has returned
into the well from the portion A. In this form the downward shoot of the ink
from the ink outlet is not requisite and the ink-conductor may open directly into
the bottom of the portion A. Figure 3 shows a type of my invented device in which:
a depressable piston replaces the diaphragm. C is the ink well, and D, the cover
hermetically sealing the same by means of a rubber packing or other suitable means..

page_text: The piston is supported by a spring or made light enough to float in the ink. On
this piston is placed the cup A provided with a conductor B constructed as in
Figure 1. I do not limit myself to this construction as any usual or convenient
form of piston construction may be employed.
Figure 4 shows a type of my device in which the ink is retained in the cup at
one side of a partition by means of a valve H, which opens and closes when the
cup is depressed and rises respectively.
Figure shows a type of my device in which the ink is retained by a valve H
having a stem extending down through the conductor. This stem may project a
little below the bottom of the conductor so that it will strike against the bottom
of the well before the conductor reaches that point, and consequently lift the
valve slightly, disengaging it if it clogs. Over this valve I sometimes place
protector n..
In Figure 6 I have shown a form of my invention in which the ink is forced into
the cup A by pressure exerted exterior thereto.. The cup and the conductor M may
be rigidly secured to the well. Communicating with the well is placed the piston F,
moving in the cylinder G, by the depression of which the ink is made to flow into
the cup A. Upon the release of the piston the ink will flow back through the
conductor B into the well C.
In Figure 7 is shown a cross section of an arrangement in which a plural ink
conductor is used to avoid the danger of clogging incident possibly to the use of a
single inlet to the cup.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The combination of an ink-well provided with a cover sealing said well,
devices for intermittently compressing the.air in said well, an ink-conductor leading
from the ink in the well into the ink-cup, and an ink-cup containing provisions
for automatically retaining the ink in the ink-cup substantially as described.
2. The combination of an ink-well, a cover sealing said well, devices actuated by
the insertion of the pen intermittently compressing the air in said ink-well, an ink-
conductor leading from the ink in the ink-well into the ink-cup, and an ink-cup
containing provisions for retaining the ink therein independently of the upward
movement of the ink in the ink-conductor, substantially as described.
3. The combination of an ink-well, an elastic cover scaling said ink-well and
operating by its depression to cause a compression of the air above the ink in the
ink-well, an ink-conductor leading from the ink in the ink-well into the ink-cup,
and an ink-cup containing provisions for retaining the ink in the ink-cup inde-
pendently of the upward movement of the ink in the ink-conductor, substantially
as described.
4. The combination, in a fountain-inkstand, of an ink-well, a cover hermetically
sealing said ink-well, an ink-cup secured thereto and moving therewith and
depressible by the insertion of the pen, an ink-conductor leading from the ink-
cup into the ink-well, and provisions in said ink-cup for retaining the ink therein
independently of the uprising of the ink in the ink-conductor, substantially as
described.
5. The combination of an ink-well, a cover sealing said ink-well and provided
with a depressible funnel, a cup containing provisions for automatically retaining
the ink in the ink-cup independently of the force injecting the ink into the
same, and a conductor leading from the ink in the ink-well into the ink-cup all
said parts operating to compress the air above the ink in the ink-well and force
the ink upward into the ink-cup, substantially as described.
