PROVISIONAL SPECIFICATION.
Improvements in Inkstands or Vessels for Holding Writing Fluid.
I, JOSEPH SMITH, of Addingham in the County of York, Painter, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in inkstands or vessels for holding
writing fluid, and its object is to always present a sufficient depth of ink or writing
fluid for the pen but avoid the liability of overcharging it.
The said improvements consist in the employment of a float, preferably in the
form of an inner vessel provided with feed openings below the level of the ink and
of such a specific gravity that it floats in the ink with its bottom a sufficient depth
below the surface to form a convenient stop or rest for the pen, or a pen stop may
be introduced at any convenient depth.
The said floating vessel may be formed of any suitable material light enough to
float in ink or if formed of heavier material may be provided with an air chamber
or chambers to cause it to float. Said vessel may be mounted in any outer reservoir
or receiver of suitable shape and capacity or they may be adapted for and applied
to existing inkstands. In which case when the form of the inkstand renders it
desirable I may introduce a float guide.
Instead of said float being in the form of a vessel it may be of any suitable
shape adapted to support a pen rest or stop a convenient distance below the
surface.

COMPLETE SPECIFICATION.
Improvements in Inkstands or Vessels for Holding Writing Fluid.
I, JOSEPH SMITII, of Addingham in the County of York, Painter, 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 :-
This invention relates to improvements in inkstands or vessels for holding
writing fluid, and its object is to always present a sufficient depth of ink or writing
fluid for the pen but avoid the liability of over-charging it.
The said improvements consist in the employment of a float preferably in the
form of an inner vessel provided with feed openings below the level of the ink and
of such a specific gravity that it floats in the ink with its bottom a sufficient depth
below the surface to form a convenient stop or rest for the pen, or a pen stop may
be introduced at any convenient depth.
The said floating vessel may be formed of any suitable material light enough to
float in the ink or if formed of heavier material may be provided with an air
chamber or air chambers to cause it to float. Said vessel may be mounted in any
outer reservoir or receiver of suitable shape and capacity or they may be adapted
for and applied to existing inkstands. In which case when the form of inkstand
renders it desirable I may introduce a float guide.
To fully describe my invention reference is made to the accompanying sheet of
drawings forming a part of this Specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, represents a diametrical section of an inkstand or ink reservoir fitted
with my improved float.

page_text: Figure 2, is a plan view of the same with the cover of the inkstand removed.
Figure 3, is a separate elevation of the float.
Figure 4, is a diametrical section of a hollow float of thin non-corrosive
metal, vulcanite, celluloid or other suitable substance fitted in a vertical guide.
Figure 5, is a diametrical section of said float guide fitted in an inkstand with
the float shown in full in position.
In Figures 1, 2 and 3 the interior of the inkstand A is approximately cylindrical
in form and is fitted with a loose cover B having a central opening C. A cylindrical
float D of wood or other suitable material is placed in the inkstand and is a little
smaller in diameter than the interior of the inkstand to leave clearance and allow
the float to rise and fall freely. A recess E is formed in the centre of the top F
of the float D and ink ducts G lead from the bottom of such recess to the outside
of the float.
Sufficient ink is placed in the inkstand to raise the float near to the top and the
ink flows into the recess E through the ducts G to the level of the fluid outside.
As the ink is used in the ordinary way or evaporates the float settles gradually
down with it but an uniform depth of ink for charging the pen is maintained in the
recess as long as there is sufficient ink left in the inkstand to keep the float afloat.
In Figures 4 and 5, a hollow float D₁ provided with an annular air chamber i
surrounding the recess E to reduce its specific gravity is shown. The ducts G
are formed in the sides of the recess at the bottom projecting below the air
chamber i.
A cylindrical float guide H adapted to be loosely slipped into the mouth of the
inkstand a is provided to keep the float approximately concentric with the mouth
in case the form of vessel requires it.
Instead of the said float being in the form of a vessel it may be of any suitable
shape adapted to support a pen rest or stop a convenient distance below the
surface. I find however the vessel form decidedly the best as the float is liable
to be more or less depressed by the action of charging the pen but as this
depression is only instantaneous it does not materially alter the depth or amount
of fluid in the vessel.
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:
1. A. float adapted to be placed in an inkstand or ink vessel and be supported
by the writing fluid and formed with a pen recess the bottom or stop of which
lies a suitable depth below the level of the writing fluid and having a duct or
its equivalent to feed said recess from the ink vessel, substantially as herein
shown and described and for the purpose specified.
2. The combination with an inkstand or vessel for holding writing fluid, of a
float having a recess or its equivalent to form a guide or stop for the pen in the
act of charging it, substantially as herein shown and described.
3. The combination with an inkstand or vessel for holding writing fluid provided
with a float, of a guide adapted to keep said float in position, substantially as
herein shown and described.
