PROVISIONAL SPECIFICATION.
Apparatus for Containing and Supplying Liquid Indian Ink, Writing
Ink, or other Liquid Colours or Liquids.
I, HUGO LUDWIG NIKEL, of Hernals, Alsbach Strasse, 17, Vienna, Accountant
Petty Officer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an apparatus for containing liquid Indian ink, writing
ink, or other liquid colours or liquids which is constructed as follows:
A vessel of any suitable forin, such as an ordinary ink bottle, has fitted air tight.
into its mouth a plug having on its upper side a space or chamber enclosed air tight
by a flexible envelope, which chamber communicates with the interior of the vessel
by means of a passage formed through the plug. Into the top of the flexible..
envelope is fitted air-tight a small tube that passes down through the chamber and
the passage of the plug, and into the vessel to near the bottom of the same, the
outer end of the said tube having a conical or other shaped cup formed or fixed
upon it.
The passage of the plug being of larger diameter than that of the tube passing
through the same, it will be seen that, assuming the vessel to be more or less filled
with Indian-ink or other liquid, on introducing a drawing or writing pen or a brush
into the cup, the weight of the pen or brush, or a slight downward pressure exerted
either on the pen or by the finger on the chamber, will cause the latter to be
compressed somewhat, so that by thus forcing some of the air out of the same into.
the ink receptacle the ink will be forced up the small tube and into the cup, so as
to supply the pen or brush therewith. On removing the pen, the elastic chamber
will rise again, and in drawing back the air out of the vessel, will cause the liquid
to descend from the cup and tube again.
For limiting the extent to which the chamber is depressed, an annular projection
constituting a stop for the flexible top part to butt against, may be formed round
the opening of the passage within the chamber, lateral grooves being made in such
projection to allow any liquid that may enter the chamber to drain back into the
vessel.
Any entrance of liquid into the chamber may however be prevented by forming
a disc on the small tube at a point just below the inner end of the plug of the
vessel, so as to close such end of the passage of the plug when the tube and flexible
chamber are in the raised position, and to leave it open when they are depressed as
described.
The vessel containing the liquid is by preference formed with a slight central
well or depression into which the tube dips, so that the liquid may drain into it
when the vessel is empty.
The above described flexible chamber and cup can be protected by a covering
cap when not in use.

Apparatus for Containing and Supplying Liquid Indian Ink, Writing
Ink, or other Liquid Colours or Liquids.
I, HUGO LUDWIG NIKEL, of Hernals, Alsbach Strasse 17, Vienna, Accountant
Petty Officer, 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 relates to an apparatus for containing and supplying liquid Indian
ink, writing ink, or other liquid colours; it consists of a vessel provided (on its
top) with a small tube the outer end of which has a conically shaped cup, and
which said tube passes through the cover of the vessel. The cover or plug of the
vessel has on its upper side a space or chamber enclosed airtight by a flexible
envelope, which chamber communicates with the interior of the vessel by means of
a passage formed through the plug.
It will be seen that a slight downward pressure of the small tube causes the
compression of the elastic hollow body or a deflecting of a membrane replacing the
hollow body. The passage of the plug being of larger diameter than that of
the tube passing through the same, it will be seen that, assuming the vessel to be
more or less filled with Indian ink or other liquid, on introducing a drawing pen or
a brush into the cup, the weight of the pen or brush or a slight pressure exerted
either on the pen or by the finger on the chamber or on the membrane will cause
the latter to be compressed somewhat so that by thus forcing some of the air out
of the chamber into the ink receptacle, the ink will be forced up the small tube and
into the cup so as to supply the pen or brush therewith. On removing the pen,
the elastic chamber will rise again, and in drawing back the air out of the vessel,
will cause the liquid to descend from the cup and tube again so that any drying of
the liquid is prevented which is very important for liquid Indian ink.
The improved apparatus is illustrated in the accompanying drawing in which
Fig. 1 is a horizontal section through the elastic hollow body.
Fig. 2 is a vertical section of the receptacle with the elastic hollow body.
Fig. 3 is a vertical section of a modification having the elastic hollow body
formed directly in the plug.
Fig. 4 is another modification in vertical section, having an elastic membrane
instead of a hollow body or envelope.
The receptacle a (Figs. 2 and 3) of any suitable size is closed by a plug (or by
any other contrivance) upon which plug is formed or attached an elastic hollow
body or envelope c through which passes airtight a small tube d and the upper
projecting end of which is provided with a conical cup e. The bore or opening of
the plug is larger than the diameter of the small tube d; the latter extends nearly
to the bottom of the receptacle, which bottom has a recess a¹.
The annular projection d2 upon the small tube d limits the extent to which the
tube is inserted, so that the lower extremity of the small tube is always a little
above the bottom or recess.
A capf fitted or screwed upon the neck prevents the small tube from being
injured.
In Fig. 2 the elastic hollow body c is above the plug b, whereas in Fig. 3 it forms
part of the latter.
la Fig. 4 is illustrated a rigid hollow body instead of an elastic one, and it is
provided with an elastic membrane. This rigid body consists of the downward
curved metal plate band of an upward bent and perforated metal disc between
which is inserted the elastic membrane c. The latter is secured in position by
screwing on the threaded flange of the plate 6. Into the membrane is suitably
fitted the small tube d. The openings of the two metal discs b b are somewhat
larger than the small tube d, so that the latter may move up and down freely.

page_text: The apparatus is used as follows :—
The capf being removed, a drawing-pen or other pen is put in the cup e, (as in
an ink bottle) and the weight of the pen &c. or a slight downward pressure exerted
either on the pen or by the finger on the chamber or the membrane c will cause
this to be compressed somewhat so that by thus forcing some of the air out of the
same into the ink receptacle the ink will be forced up the small tube and into the
cup, so as to supply the pen &c. therewith. On removing the pen the elastic
chamber or the membrane will rise again and in drawing back the air out of the
vessel, will cause the liquid to descend from the cup and tube again.
In order to be enabled to use the last drop, the bottom is provided with a
recess a¹.
In order to allow any liquid that may enter the chamber c to flow off again when
the vessel is inclined, the ring (Fig. 1), limiting the extent of depression of the
hollow body, is provided with radial slots c¹ through which the liquid may
flow off.
In order to prevent any liquid from entering into the hollow body c, I apply a
flange d' upon the small tube d, which flange bears always tightly against the lower
plug-surface or against the lower disc b, and closes the bore or opening leading into
the chamber from the receptacle a.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for containing and supplying liquid Indian ink, writing ink or
other liquid colours or liquids, consisting of a hollow body c (Figs. 2 and 3) or of
an elastic membrane c (Fig. 4) inserted into a rigid hollow body b b₁, and of a small
tube d with cup-like enlargement which tube is supported by the elastic hollow
body (Figs. 2 and 3) or by the membrane (Fig. 4) and extends into the interior of
the receptacle, whence the liquid rises into the small tube, as soon as the air is
compressed in the receptacle by the depression of the hollow body or the membrane,
substantially as set forth.
2. In the apparatus referred to in the first claim, the application of a flange d¹ on
the small tube d below the plug b (Fig. 3), or the disc 6 (Fig. 4) for closing the
hollow body against ingress of liquid from the receptacle.
3. In the apparatus referred to in the preceding claims the formation of a
depression or recess a¹ in the bottom of the vessel in order to enable the last
quantity of liquid to be utilised, substantially as described.
