PROVEMENTS IN OR CONNECTED WITH INKSTANDS OR INK BOTTLES AND OTHER
VESSELS FOR HOLDING LIQUIDS."
The object of my Invention is to prevent ink or other liquids being spilled from
the inkstands or other vessels which contain them, and to keep them from contact
with the air and dust.
The Invention consists, first, of a special dipping cup open at the bottom, and in
the form of a double truncated cone; it is movable or fixed and is applicable to the
mouths of inkstands, bottles, and other vessels and recipients, and to lamps, floating
lights, acid containers, and other like articles. This cup which is of glass, metal, or
other material is made in one piece, or in two pieces with a joining ring, so as to be
in the form of two cones or funnels superposed and fitted together. The upper and
inner cone which extends to about half the depth of the outer and lower cone opens
into the cup by a hole, sensibly larger than that at the bottom of the lower cone.
It is by this contracted orifice only that the ink can rise from the inkstand into the
cup. There are two ways of employing this cup; it may be used alone at the
mouth of any inkstand; in this case it is surrounded near the top with a
ring of caoutchouc, leather, cork, or other elastic material, which allows of its
being applied at once to the mouth of an inkstand or other vessel intended to
contain liquid.
The second part of my Invention consists in applying this double coned cup to an
inkstand or vessel by means of a special mounting or fitting having an obturator,
which is displaced circularly as about to be explained.
The mounting or fitting is composed of a metal capsule or cup applied to the neck
of the inkstand or vessel. Within this capsule a closing plate or cover is moved
horizontally turning round a vertical axis at the side of the vessel and operated by
a button; this plate slides through a slit in the side of the capsule, and is in
hermetic contact with a caoutchouc or cork washer supported by an under plate.
The cup is in this case made with an upper metal shoulder, which is screwed into
the capsule threaded internally for the purpose. The capsule is connected to the

page_text: inkstand by means of a threaded ring on the neck, to which the capsule is screwed.
The edges of the ring press against a caoutchouc ring placed under the upper
shoulder above mentioned. Washers of cork, caoutchouc, or other flexible material
should be interposed between the said shoulder and the under plate above referred
to, against which the cup is made to press. In this way the joints are hermetic,
preventing the air entering or the liquid getting into the screw threads and so
escaping. The liquid should be put into the vessel before the cup is fitted.
When it is required to use the inkstand or vessel the closing plate before
described is moved horizontally by means of its button, so as to uncover the
opening.
