I, HERMANN KLETTE Manufacturer of Buchholz in the Kingdom of Saxony and
German Empire 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 improved ink pot is made in a simple manner which satisfies all demands that
can in a general way be made upon it by placing two suitably shaped vessels A and B
one inside the other.
The two vessels are of suitable shape, the large one A intended to receive the ink is
hollowed out cylindrically and has in the middle of its bottom which may sink in the
form of a flat funnel a simicircular raised piece C and when the smaller vessel B
placed inside the other is likewise hollowed out cylindrically and has in the middle of
its bottom a small aperture D the edge of which rises to almost the outer edge of the
vessel so that the bottom seen from the outside forms a funnel with walls which are
not rectilineal but in curves the centres of which lie near the wall of the outer vessel.
In addition the measurements of the two vessels must bear such a proportion to
each other that the smaller one can only move up and down with but little play and
therefore like a piston in the larger one, but cannot turn over. The turning over is
prevented by a proper calcuation of the height and also by providing the outer walls
with ribs F which secure a narrow path for the small vessel in the large one but at
the same time only present a small friction surface.
If the vessels are made as herein described and as duly shown in the drawing and
are put together in the manner indicated it only remains to fill the inkpot to have it
ready for use. By the ink introduced into the large vessel the bent down ring-shaped
aperture in the small funnel vessel is closed and the air therein contained is thus
shut off. This raises the vessel and keeps it swimming in the ink. The weight of
the funnel vessel and the quantity of air contained in it are to be calculated so that
through the lower aperture so much ink can pass into the funnel as is just necessary
to completely fill the pen dipped in it. By using a hook shaped bent tube the
smaller arm of which is inserted sideways under the funnel vessel into the space filled
with air while the longer arm projects over the edge of the large vessel the dipping

page_text: depth can always be regulated at will by either introducing air through the tube and
thus diminishing the dipping depth or vice versa by drawing off air and increasing
the depth.
The advantages of this new ink pot with its pneumatic piston funnel lid are evident.
In enumerating them herein I will at the same time explain the not yet detailed
particulars of its construction.
As the effect of the shape given to the funnel is that the pen on being dipped in
always glides towards the middle of it the receiving place for ink always lies in the
middle of a widely open vessel. The pen when filled therefore does not as a rule in
being withdrawn streak the walls of the funnel or of the ink pot itself on the contrary
they remain clean and the pen when dipped in again does not therefore get dirty with
streaks of ink. Pen holder fingers and paper are all kept clean.
The ink sediment deposits itself on the bottom of the large vessel. Out of the
latter rises the semicircular raised piece C the cap of which rises out of the sediment
but in consequence of its shape remains free from sediment. The swimming funnel
covers the whole of the bottom of the vessel but not the raised portion lying under
the apperture D (which latter may be made greater or smaller as desired). This
alone is therefore accessible to the nib but as it is free from sediment the nib also
cannot go into the sediment of the ink and thus the writing remains spotless and
clean.
The swimmer B always has the same immersion in the ink consequently the height
of the ink in the funnel is always the same and the depth to which the pen must be
dipped. No special attention therefore necessary in dipping and the troublesome
smudging caused by filling the pen too full is avoided.
The striking of the pen against the glass is an elastic blow because the swimmer
gives a little. Thus the pens are spared.
The funnel lid covers almost the whole of the upper surface of the ink hence but
little evaporation takes place and the ink consequently does not get thick.
The ink collects to the very last drop in the aperture of the funnel so that almost
all the ink can be used up.
The various parts and the whole are easy to handle and to clean.
There is nothing to make it difficult to construct them in glass china etc. which is
therefore not attended with much trouble or expense.
The external shape may vary in an unlimited degree and every taste can therefore
be easily suited.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed 1 declare that what I claim is :-
An ink pot in which by means of two vessels such as A and B placed one inside the
other the outer one being provided with a raised piece C in the centre of its bottom
and intended to receive the ink and the other being placed inside it piston like forming
a floating lil with a funnel for dipping-the dipping depth is limited an elastic blow
is secured and the sediment of the ink cannot reach the pen and the ink is sufficiently
protected from the outer air substantially as hereinbefore described and represented
in the accompanying drawings.
