PROVISIONAL SPECIFICATION.
Improvements in Inkpot or other Vessel to Contain Ink or other
Fluids, for Preventing a Pen or other Instrument from Taking
Up More Fluid than Required.
I, JOSEPHINE SIDNEY SARAH ALBERTA BUSSELL Married Lady of Alberta House
Dickenson Road Hornsey Middlesex do hereby declare the nature of this invention to
be as follows :-
Inkpot or other vessels, made of Glass, Earthenware, China, Metals, Wood, Paper
Pulp or other suitable materials, to contain Ink or other fluid having its inside
bottom, graduated, sloped, or stepped round a central pillar, in order to form varying
depths round the pillar, so that by means of a hole in an adjustable lid a pen or
other instrument can be inserted only to the depth required.
Dated this Twenty first day of February 1889.
COMPLETE SPECIFICATION.
Improvements in Inkpot or other Vessel to Contain Ink or other
Fluids for Preventing a Pen or other Instrument from Taking
Up More Fluid than Required.
I JOSEPHINE SIDNEY SARAH ALBERTA BUSSELL of Alberta House Dickenson
Road, Crouch Hill, in the County of Middlesex, do hereby declare the nature of my
said 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 my invention is to effect improvements in inkpots or other vessels,
made of glass, earthenware, china, metal, wood, papier maché, or other suitable
materials; whereby the dip of the pen, or other instrument, into the fluid, can be
regulated and controlled, and rendered definite and certain; irrespective of the
height or level of the ink or other fluid contained therein.
In carrying out some forms of my invention, I vary the depth of the vessel by
making the bottom of various thicknesses, or by raising the bottom to various heights.
This may be effected by making the bottom inclined from one side to the other; or
by making it helical round a central point, cylinder, well or pillar; or by forming
a circular or other series of steps round a central point, cylinder, well, or pillar, or
by otherwise varying the depth.
The covers to the vessels above described are made movable, and a hole for the
passage of the pen or other instrument is made in an excentric position. Another
hole in a central position, is also formed therein, when a separate supply of ink or
other fluid is required and for which the central well is applicable.
The depth of the dip of the pen, or other instrument, and consequently the quantity
of fluid taken up thereby depend upon the position of the excentric hole in the
cover, whether it is over a deep or shallow part of the inkpot or other vessel, and
also upon the quantity of fluid therein.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which some examples
are shown, illustrating the nature of my said invention, and in which similar letters
of reference indicate corresponding parts.
Fig. 1 is an elevation, Fig. 2 a plan and Fig. 3 a section on the line 1-2 of
Fig. 2. Fig. 4 is a plan, and Fig. 5 a section on the line 3-4 of Fig. 4.
Figs. 6, 7, and 8 illustrate other modifications of my invention.

page_text: Referring to Figs. 1, 2, and 3, a is the body of the inkpot. 6 is a movable lid
fitting the pot a so as to be capable of being turned upon its centre.
c is a central
'movable cup placed in the well for containing ink or other fluid of a different kind
to that contained in a. d is a helical bottom, starting from its lowest position at d¹,
and rising in the annular space to its highest position at d², where a step is formed.
k is a hole for the entrance of the pen, its position being made to suit the depth of
fluid in the annular space. The movable cup c may be dispensed with, and the
fluid may be placed directly into the central well, or a solid central cylinder may be
formed in the centre, or it may be dispensed with altogether. The cylinder itself
may also be made movable, and may be made to fit into a central aperture surrounded
by the helice.
m is a central hole in the lid b, for the entrance of the pen to the fluid in c.
The bottom d may be made solid, increasing in thickness from d¹ to d² or raised
as shown in Fig. 3.
In Figs. 4 and 5 the inkpot is shown of a rectangular form, the bottom being
made of four different levels, e being the lowest and f g h three successive rising
levels.
f
The lid may be so placed that the opening k will be over either of the levels e
gh, according to the depth of fluid and the quantity required to be taken up.
I sometimes form a cylindrical or conical collar under the opening k forming part
of the cover, to guide the pen or other instrument.
In the modification shown in Fig. 6 the bottom d is made slanting from one side
to the other, so as to provide for a varied depth of fluid. The bottom may be made
solid as shown, or hollow, or the external surface may also be inclined and supported
upon a slanting stand.
In Fig. 7 the vessel a consists of a single formation, intended to be used upon a
slanting desk or stand; the vessel being turned upon its centre to such a position
that the opening k is immediately over the required depth of fluid.
Fig. 8 is a plan showing a circular vessel with provision for six different depths e f
ghij and a central well c.
It is obvious that the horizontal section may be very much varied, and may be
made circular, square, polygonal, or of other form, and that the variations in depth
may be gradual or in successive steps or otherwise.
In some cases I form raised ledges to the steps to prevent the pen, slipping off
the step, when inserted.
The holes in the covers for the insertion of the pen may in all cases be fitted
with suitable sliding or other caps or covers for keeping out the dust, when not
in use.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improved construction of inkstands, the cover of which is formed with a hole
for the passage of the pen, in an excentric position, whereby in combination with
the formation or position of the bottom, the depth of ink immediately under the
excentrically placed pen-hole can be regulated and adjusted substantially as herein-
before described and illustrated by the drawings.
Dated this 16th day of October 1889.
