PROVISIONAL SPECIFICATION.
Improvements in Inkstands and like Vessels for Holding Liquids.
of Various Kinds.
I, WILLIAM THOMAS SHAW, of 110 Bunhill Row; in the City of London;
Manufacturer, do hereby declare the nature of this invention to be as follows:-
In the Specification of a former Patent granted to me No. 17292 in the year 1887
I described an inkstand in which a float consisting of part of a solid of revolution
which fitted and was free to turn in the lower part of the reservoir containing the
ink was made to keep the ink at an approximately constant level in the reservoir-
and in a small well in communication therewith.
The object of my present invention is mainly to construct inkstands in such a
manner that the level of liquid in the well shall remain unaffected by any
rocking or oscillation to which the inkstand may be subjected when for example-it
is used on board ship.
To effect this, in place of making the dipping well to communicate directly by a
short passage with the interior of the reservoir as heretofore I make it to com-.
municate with the reservoir by a passage which is led around the exterior of the
reservoir to a point opposite to that at which the well is situated and to open into
the reservoir at the level of the liquid or nearly so.
When the inkstand is formed in this way any inclination of the inkstand in a
direction to lower the well would not materially alter the level of ink in the well'
as the orifice by which ink flows from the reservoir to the well would be raised.
above the liquid level. Any oscillation in the opposite.direction would not 'empty.
the well of ink if the ink supply passage were led into the side of the well at 'a
distance from its bottom.
The inclination of the inkstand in either direction around an axis in a line with
the well and ink supply orifice at the back would have no tendency to alter the ink
level in the well.
The inkstand can therefore be subjected to considerable shaking or oscillation
without ink being thrown out from the well or the ink level in the well being
materially altered. If also the inkstand were to be upset the only. ink that would
flow from it would be that contained in the well. Vessels for holding liquid gum or
other liquids may be formed in the same way.

COMPLETE SPECIFICATION.
Improvements in Inkstands and like Vessels for, Holding, Liquids,
of Various Kinds.
I, WILLIAM THOMAS SHAW, of 110 Bunhill Row, in the City of London,
Manufacturer, 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:-
a
✓ In the Specification of a former Patent granted to me No. 17292 in the year
solid of
1887 I described an inkstand in which a float consisting of part of
revolution which fitted and was free to turn in the lower part of the reservoir con-
taining the ink was made to keep the ink at an approximately constant level in the
reservoir and in a small well in communication therewith.
The object of my present invention is mainly to construct inkstands in such a

page_text: manner that the level of liquid in the well shall remain unaffected by any rocking
or oscillation to which the inkstand may be subjected when for example it is used
on board ship.
To effect this, in place of making the dipping well to communicate directly by a
short passage with the interior of the reservoir as heretofore I make it to com-
municate with the reservoir by a passage which is led around the exterior of the
reservoir to point opposite to that at which the well is situated and to open
into the reservoir at the level of the liquid or nearly so.
When the inkstand is formed in this way any inclination of the inkstand in a
direction to lower the well would not materially alter the level of ink in the well as the
orifice by which ink flows from the reservoir to the well would be raised above the
liquid level. Any oscillation in the opposite direction would not empty the well of
ink if the ink supply passage were led into the side of the well at a distance from its
bottom.
The inclination of the inkstand in either direction around an axis in a line with
the well and ink supply orifice at the back would have no tendency to alter the ink
level in the well.
The inkstand can therefore be subjected to considerable shaking or oscillation
without ink being thrown out from the well or the ink level in the well being
materially altered. If also the inkstand were. to be upset the only ink that would
flow from it would be that contained in the well. Vessels for holding liquid gum
or other liquids may be formed in the same way.
The drawing annexed is a vertical section of an inkstand formed as above
described.
A is the lower part of the reservoir containing the ink and A' its cover-
these forming together a reservoir which is of spherical form on the interior. B is
the float concentric with the interior of the reservoir and suspended on pivots as
described in the Specification of the before mentioned Patent. C is the dipping
well and D the passage by which ink passes from the reservoir to the well.
The inkstand shown is made in pressed glass-the passage from the well to the
rear of the reservoir is formed of a tube of vulcanite which lies in a groove or recess
formed across the interior of the reservoir and is bedded into it with a suitable
cement preferably with marine glue. The cover A' is also cemented preferably
with marine glue to the top of the reservoir and a watertight joint made.
A² is
the air inlet at the top of the cover A.'.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is
1. An inkstand or like vessel formed with a reservoir having pivotted within it a
float which is of half the specific gravity of the ink or fluid that the reservoir is to
hold a dipping well at one side of the reservoir and a small passage leading from
the dipping well to the opposite side of the reservoir.
2. An inkstand or like vessel formed substantially as hereinbefore described and
illustrated by the drawing annexed.
