PROVISIONAL SPECIFICATION left by the said Frank Wirth at the Office
of the Commissioners of Patents on the 6th January 1883.
FRANK WIRTH, of the firm of Wirth and Company, Patent Solicitors, at
Frankfort on the Main, in the Empire of Germany, "IMPROVEMENTS IN INK-
STANDS "[A communication from Heinrich Meidinger, Professor and Doctor of
Philosophy a person resident at Karlsruhe in the Empire of Germany.]
This Invention relates to ink-bottles or ink-stands.
According to the said Invention the body of the ink-stand, which is composed of
a solid and impervious material and may be of any suitable cross section, is
provided at the top and bottom with peculiarly shaped depressions connected by a
small opening. At the lower part of the said body a groove is formed which holds
the edges of an elastic disc. The exterior of the said body which is circular in
horizontal section, is provided with a screw thread upon which is fitted a cap of
metal or other suitable material, the bottom of which is curved to correspond with
the depression in the bottom of the body part. The ink-reservoir proper is situated
between the said bottom and the inner side of the said cap. When the body part
is screwed down into the said cap, the ink-reservoir is reduced in size, and the ink
will rise through the said small opening into a dipping cup formed above it, the
depth whereof is such that the pen can take up precisely the requisite quantity of
ink.

page_text: By screwing the body part far enough into the cap the ink can be emptied out
of the ink-reservoir.
When filling the ink-bottle, the cap is unscrewed as far as possible, and the ink
is poured into the depression upon the upper side of the body part.. When not in
use, the dipping cup can be emptied and the ink preserved from drying up, by
slightly unscrewing the body part.
Instead of the elastic disc, a suitable packing may be used, in which case the
bottom of the body part, and of the cap may be made level.
If the ink-stand be made somewhat high, or in other words, if the dipping cup
bo sunk rather deep, the packing may be dispensed with, as the ink being below
the level of the edge of the cap, cannot run out.

FRANK WIRTH, of the firm of Wirth and Company, Patent Solicitors, at
Frankfort-on-the-Main, in the Empire of Germany, "IMPROVEMENTS IN INK-
STANDS. A communication from Heinrich Meidinger, Professor and Doctor of
Philosophy, a person resident at Karlsruhe, in the Empire of Germany.

This invention relates to ink-bottles or inkstands. In an inkstand it is advan-
tageous, to maintain the ink at a constant level, in order that a pen, when dipped
into the said ink, should only take up a sufficient quantity; to prevent penholders
from becoming soiled and the ink from evaporating; and to permit all the ink to
bo consumed. Ordinary inkstands possess none of the above advantages; there are
several however which possess one or more of them although not all.
The object of the present invention is to construct an ink stand which will
combine all the above mentioned advantages and it consists essentially in the
novel construction and arrangement of parts as hereinafter described.
In the accompanying drawing
Figure 1 is a sectional view of an inkstand constructed according to this
invention
Figures 2 and 3 are similar views illustrating modifications and hereinafter
described.
According to the said invention the body A of the inkstand which is composed of
a solid and impervious material and may be of any suitable height is provided at
the top and bottom with depressions connected by a small opening. At the lower
part of the said body a groove d is formed which holds the edges of an elastic disc.
The exterior of the said body which is circular in horizontal section is providerl
with a screw thrend h upon which is fitted a cap i of metal or other suitable
material, the bottom of which is curved to correspond with the depression in the
bottom of the body part A.
The ink reservoir b is situated between the said depression and the inner side of
the elastic disc c. When the body part A is screwed down into the cap i the said
disc is brought nearer the bottom of the said body part whereby the ink reservoir b
is reduced in size and the ink will rise through the small opening between the
depressions into the dipping cup a formed above it, the depth whereof is such that
the pen can take up precisely the requisite quantity of ink. By screwing the body
part A far enough into the cap i the ink can be emptied out of the ink reservoir b.
When filling the ink bottle the cap i is unscrewed as far as possible, and the ink is
poured into the depression in the upper side of the body part.
When not in use the dipping cup a can be emptied, and the ink preserved from
drying up, by slightly unscrewing the body part A.
Instead of the elastic disc, a suitable packing may be used, in which case the
bottoms of the body parts A, and of the cap i may be made flat.
હું
If the inkstand be made somewhat high, or in other words if the dipping cup a
be sunk rather deep, the packing may be dispensed with, as the ink being below
the level of the edge of the cap i, cannot run out.
According to a modification of this invention as shown in Figure 2 the metal
cap i is dispensed with and the body part A is of such a form as to serve as a
bottom for the said inkstand. Within the said bottom part is fixed a plate f
having in its centre a screw stud carrying a plate 9 which is adapted to bear
gainst the underside of the disc c. By screwing the said plate 9 upward the ink
will be forced into the dipping cup a in the manner herein before described.

page_text: According to another modification shown in Figure 3 the metal plate g is used as
herein beforo described, but in this case it is mounted upon one end of a lever {,
(having a suitable fulcrum on the plate f) upon the other end of which bears a
scrow 8 suitably arranged in the body part A; by screwing the screw & downwards
the plate g will be forced upwards against the elastic disc as before described.
Having thus fully described the said invention as communicated to me, and the
manner of performing the same, I wish it understood that I claim in an inkstond
First. The body A having depressions in the top and bottom, and the dipping
cup a, the said bottom depression serving as an ink-reservoir and being connected
with the dipping cup by means of a channel, the said ink reservoir being provided
with a groove, substantially as, and for the purpose, specified.
Second. The disc c which forms the bottom of the ink-reservoir, and which,
on being pressed, forces the ink out of the said reservoir, substantially as described.
Third. The means substantially as described with reference to cither of the
figures of the drawing, for pressing upon the bottom of the disc c for the purpose
specified.
In Witness whereof I the said Frank Wirth have hereunto set my hand and
seal this Third day of July in the year of our Lord One thousand eight
hundred and eighty three.
