TRUVINIONAL OF POTTY
A New or Improved Self-supplying Ink Bottle.
I, JAMES JOSEPH DUFFY, of Carrickmacross, in the County Monaghan,
Ireland, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to a new or improved self-supplying ink bottle for
the purpose of preventing evaporation and thickening of ink, and also preventing
dust from entering the bottle, and further for the purpose of securing that the pen
be maintained in a clean condition.
In carrying out my invention I propose to form a reservoir of suitable shape.
and dimensions, the lower part of which communicates with an orifice arranged in
front, the communicating passage being of such dimensions as to admit of only a
small quantity of ink to flow from the reservoir, and only as required by the
insertion of the pen. Thus the ink flows only when the pen is introduced, and in
the quantity required to furnish each insertion of the pen.
For the purpose of charging the reservoir I form a suitable stoppered aperture
in a convenient position-preferably in the bottom of same.
With an ink bottle of this construction the contents cannot spill, no matter how.
the vessel may be knocked about.

I, JAMES JOSEPH DUFFY, of Carrickmacross, in the County Monaghan,
Ireland, Merchant, 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:-
This invention has reference to a new or improved self-supplying ink bottle for
the purpose of preventing evaporation, and thickening of ink, and also preventing
dust from entering the bottle, and further for the purpose of securing that the pen
be maintained in a clean and workable condition.
In carrying out my invention, I propose to form a reservoir of suitable shape.
and dimensions, the lower part of which communicates with an orifice or fountain
arranged in front, the communicating passage being of such dimensions as to
admit of only a small quantity of ink to flow from the reservoir, and only as
required by the insertion of the pen, and also set an inclined angle to prevent the
entrance of dust to the reservoir.
my
The accompanying drawings will enable my said invention to be more readily
understood, in which Fig. 1 is a side elevation; and Fig. 2 a vertical section of
improved self-supplying and dust-proof ink bottle:-A, is the reservoir which, it
is obvious may be formed of any convenient size and shape, and of any suitable
material, according to requirements.

page_text: B, is the ink-well, the entrance to which is dished or flared as shewn for the
two-fold purpose of facilitating the introduction of the pen and providing for the
rising or swelling of the ink in the event of disturbance by abnormal atmospheric
pressure in the reservoir.
C, is the communicating or supply passage which is set at an inclined angle in
order to prevent the entrance of debris to the reservoir, and ensure the deposit of
same in the bottom of the ink-well from which it can readily be removed by means
of a piece of sponge or linen attached to the handle of the pen, or otherwise at
pleasure.
D, is the opening, which I prefer to form in the bottom of the reservoir for the
purpose of introducing the ink, and which may be secured by a plug or stopper of
india-rubber, cork, or other suitable material.
The advantage of providing the charging orifice in this position is, that it does
not present so convenient a means of being tampered with, and also it ensures the
certainty of the stopper or plug being air-tight, since if not, an escape of ink
will be the result.
It is obvious that for the proper working of my invention it is necessary that
the reservoir should be air-tight, hence the desirability of having the said charging
orifice in a position necessitating its being securely stoppered or pluged.
As thus constructed the action of my improved ink bottle is obvious:-
The ink flows from the reservoir into the ink-well as required, thus keeping up
a constant and regular supply so long as the reservoir is charged.
The depth of the ink-well being limited a superfluous quantity of ink cannot be
taken up by the pen, and thus economy is effected, while the pen is preserved in a
clean and workable condition.
Another advantage of my improved ink-bottle is that its contents cannot readily
be scattered no matter how it may be knocked about.
On the top of the ink-well slots E, may be formed for the purpose of holding
the pen when not in use. This position will partly prevent the introduction of a
pen which may be used for a different ink to that in the bottle over which the pen
is thus placed.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that
what I claim is :-
The use and application of a vessel for holding ink, constructed, and arranged,
in the manner substantially as herein specified and set forth.
