I ROBERT GEORGE CHIPPERFIELD of 282 Kennington Park Road, Surrey,
Gentleman, do hereby declare the nature of my, said invention for "AN
IMPROVEMENT IN AND CONNECTED WITH INKSTANDS to be as follows: -
The object of this invention is to arrango an appliance to be attached to Ink-
stands formed with a dip well and having an air tight reservoir or chamber
surrounding it for the purpose of injecting air into such chamber above the level
of the ink so as to exert a pressure upon it and cause a quantity of the ink to pass
from below into the dip well ready for use.
For the purpose of my invention I attach to some part of the rim or top of an
inkstand a socket cup provided with a stem which hermetically seals the hole in
which it is placed. This cup has an india rubber ball of special make cemented in
it and the ball has a hole at its exposed portion, and a teat slit or its equivalent
in the portion which is over the opening in the stem. The vessel or inkstand is
formed with a chamber between the side wall and the dip well after the inkstand
is charged with ink the chamber serves for the admission of a further quantity of
air thereto at each compression of the ball, the additional supply of air forcing the
ink up the dip well at each air supply. The teat slit or its equivalent at the
bottom of the ball closes after each compression and the air within the chamber
maintains the ink in the dip well. I fit a cover to the dip well and this may be
hinged to the socket of the ball or otherwise.

Gentleman, 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:-
The object of this invention, is to arrange an appliance to be attached to
Inkstands formed with a dip well having an air tight reservoir or chamber
surrounding it for the purpose of injecting air into such chamber above the level
of the ink so as to exert a pressure upon it and cause a quantity of the ink to pass
from below into the dip well ready for use.
For the purpose of my invention, of which Figure 1 of the annexed drawings is
a sectional elevation and Figure 2 a plan, I attach to some part of the rim or top A
of an inkstand B a socket cup C provided with a stem D which hermetically seals.
the hole E in which it is placed. This cup has an india rubber ball For its
equivalent of special make in it and the ball F has a hole G at its exposed
portion H or its equivalent, and one or more lancet or teat slit in the portion
which is over the opening in the stem D.
The vessel or inkstand B is formed with a chamber I between the side wall and
the dip well J, after the inkstand is charged with ink the chamber I serves for the
admission of a further quantity of air thereto at each compression of the ball F
(shown compressed at Figure 3), the additional supply of air forcing the ink up
the dip well J at each air supply. The teat slit or its equivalent at the bottom of
the ball F closes after each compression and the air within the chamber I maintains
the ink in the dip well. I fit a cover to the dip well and this may be hinged
to the socket cup C of the ball or otherwise.
The upper part A of the glass may be so moulded as to form a socket for the
ball F, said ball F being held in the socket by a brass ring or otherwise.
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. The employment of a compressible hollow body provided with a hole which
can be closed and the air contained within it forced through lancet slits arranged
at the lower part thereof into the interior of a reservoir inkstand for determining
the height of the ink in the dip well as described' with reference to the annexed
drawings.
2. The particular construction and arrangement of reservoir inkstand shown on
the annexed drawings provided with a cup and a compressible bulb as and for the
purpose described.
