Improvements in Inkstands.
I, EMRY DAVIS, of Kane, in the County of McKean, and State of Pennsylvania,
United States of America, Bank Cashier, do hereby declare the nature of this invention
to be as follows :-
The object of my invention is to provide an inkstand so constructed as to almost
entirely avoid the evaporation of ink; and to this end my invention consists principally
of a float and dip-funnel, the float being placed loosely in a tube fitted in an air-tight
cover of the ink-well so that pressure on the float will depress it and cause the ink to
rise and fill the pen. Upon removing the pressure the float rises and the ink recedes
so that only a very small surface is exposed to the atmosphere. My invention also
consists of means for retarding too rapid entrance of the ink to the dip-cup.
The ink-stand or well is closed air tight by a cover formed, in one instance, of an
inner annular and concaved disc of soft rubber and an outer ornamental metal cover
flanged and screw-threaded and secured to the stand. A tube, fitted in the cover,
reaches nearly to the bottom of the ink-well and projects somewhat above the
cover where it is provided with a small ring in which fits a small annular cap which
holds the tube. The tube has a flange with which the central opening of the rubber
disc is drawn in close contact so that the said tube is held air-tight in the cover, and
over or above the flange is placed a small soft rubber ring to ensure an air-tight con-
nection. A ring is screwed to the upper end of the tube and serves as a nut to con-
nect the tube to the cover. The outer edge of the soft rubber disc is, by preference,
somewhat thickened or enlarged to form a cushion between the upper edge of the ink
well or stand and a flat portion of the metal cover so that when this outer cover is
screwed down the cushion will be compressed and the cover as a whole made air tight
upon the stand. The float is received in the said tube and in the float is fitted the dip
tube which reaches up through the cover. The lower end of the tube is open at the
bottom to receive the ink.
In some cases, I use a light coiled spring or spring of rubber at the bottom of the
float to lift it suddenly in the tube and this spring may be made fast in the inkwell, or
its lower end may be bent to one side to prevent the float from escaping from the
tube in case the inkstand should be upset.
When in use, the float is held, by the buoyancy of the ink, up as far as it can go
in the tube, and to fill the pen with ink it is placed in the upper end of the dip-tube
and pressed down so as to force down the float so that the air being confined above
the surface of the ink causes the ink to rise in the dip-tube. On removing the pen, the
float is elevated and the ink recedes in the dip-tube.
In another arrangement, the dip-cup is permanently attached to the cover, and the
cover is without rubber cushions, and the tube containing the float is attached to the
cover, the float being depressed by the direct contact of the pen with the upper end
thereof. When so depressed the ink is forced up side passages in the float and when
pressure on the float ceases, the float rises and the ink recedes and the upper end of
the float closes the dip-cup automatically.
In another arrangement the float is hollow and provided with a permanent tube
the upper end of which is enlarged and screw-threaded. This enlarged portion
projects through an auxiliary cover which is screwed to a collar on the main cover,
instead of to the float tube, as in the first case, and in the upper end of the said tube
is screwed the funnel or dip cup, made as a separate part. The lower end of this dip
cup or funnel is formed with a check piece with side apertures for the ink, which
serves to prevent too rapid upward gush of the ink when the float and cup are pressed
down by the pen. The cover is formed with a plate to which the float tube is attached.

page_text: The space above the plate forms an everflow chamber to receive any ink that may
overflow the top of the float tube so that no ink can find its way to the outside of the
inkstand, not even if the stand be upset, except what might at the time be contained
in the dip-cup. A rubber disc may be used with this form of stand, if desired:

COMPLETE SPECIFICATION.
Improvements in Ink-stands.
I, EMRY DAVIS, of Kane, in the County of McKean, and State of Pennsylvania
United States of America, Bank Cashier, do hereby declare the nature of this inven-
tion 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 provide an inkstand so constructed as to almost
entirely avoid the evaporation of ink; and to this end my invention consists principally
of a float and dip-funnel, the float being placed loosely in a tube fitted in an air-
tight cover of the ink-well so that pressure on the float will depress it and cause the
ink to rise and fill the pen. Upon removing the pressure, the float rises and the ink
recedes so that only a very small surface is exposed to the atmosphere.
My Invention also consists of means for retarding too-rapid entrance of the ink to
the dip-cup.
The Invention also consists of the construction and arrangement of parts, all as
⚫hereinafter described and claimed.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion, in which figure 1 is a sectional elevation of my new inkstand; Figure 2 is a
sectional plan view, taken on line - figure 1; Figure 3 is a sectional view, on
line y y figure 1; Figures 4 and 5 shew modifications of the inkstand; Figure 6 is a
sectional view of the most approved form; Figure 7 is a plan view of the same; and
figure 8 is a sectional view of the dip-cup removed, shewing means for retarding the
upward gush of ink in the tube at a time of dipping the pen. Similar letters of
reference indicate corresponding parts in all the figures.
A represents an inkstand or well of glass or other suitable material closed air-tight
by a cover B. This cover, in figure 1, is formed of the inner annular and concaved
dise B' of soft rubber and the outer ornamental metal cover 12 flanged and screw-threaded
and secured to the stand A, as shewn at B³ figure 1. In the cover B is fitted the
tube which reaches nearly to the bottom of the inkwell and projects somewhat above
the plate B2 where it is provided with the small ring D in which fits the small annular
cover E which holds the tube C. The tube C is formed with a flange band the
central opening of the rubber disc B' is drawn in close contact with this flange so that
the said tube is held air-tight in the cover, and over or above the flange b is placed the
*small soft rubber ring d to act in connection with the soft rubber disc B' to make an
air-tight connection between the tube and cover. The ring D is screwed to the upper
end of the tube and serves as a nut to connect the tube to the cover and when said
nut is screwed down the ring d is compressed between the flange band the inner
surface of the outer cover B². The outer edge of the soft rubber dise B' is, by
'preference, somewhat thickened or enlarged, as shown at f, to form a cushion between
the upper edge of the inkwell or stand A. and the flat portion f¹ of the metal cover B
so that when this outer cover is screwed down upon the threads of the inkwell the
cushion will be compressed and the cover as a whole, made air-tight upon the stand.
In the said tube C is placed the float F in which is fitted the dip-tube G which reaches
up through the annular cover E. The lower end of the tube G, is open at the bottoni
to receive the ink.
In soine cases, I use a light coiled spring or spring of rubber at the bottom of
the float to lift it suddenly in the tube Cand this spring may be made fast in the

page_text: Inkwell or its lower end may be bent to one side to prevent the float F from escaping
from the tube C in case the inkstand should be upset.
In use, the stand being supplied with ink, the float will be held by the buoyancy of
the ink up as far as it can go in the tube C, as shewn in full lines in figures 1, 4, and 6¹..
To fill the pen with ink, it is placed in the upper end of the dip-tube and pressed
down. This pressure will force down the float and the air being confined above the
surface of the ink will cause the ink to rise in the dip-tube, as indicated in figure 6.
On removing the pen the float will be elevated and the ink will recede in the dip-tube,
so that there will be practically no evaporation.
In figures 4 and 5, the dip-cup H is permanently attached to the cover B* and the
cover is without rubber cushions and tube C is attached to the cover and the float F
is to be depressed by the direct contact of the pen with the upper end thereof. When
so depressed the ink is forced, up the side passages a a made in the float, to the pen
and when pressure on the float ceases, the float rises and the ink recedes and the upper
end of the float closes the dip-cup H automatically, and effectually provents the
evaporation of ink.
In figures 6, 7, and 8, the float F is hollow and provided with a permanent tube F¹
the upper end of which is enlarged and screw threaded. This enlarged portion projects
through the auxiliary cover E, which is similar to the small cover in figure 1 only in
this instance it is scrowed to the collar on the main cover B instead of to the tube C,
as in figure 1, and in the upper end of the said tube is screwed the funnel or dip cup J,
made as a separate part. The lower end of this dip-cup or funnel is formed with a
check piece
(see figure 8) with side apertures ii for the ink. This check pieco
serves to prevent too rapid upward gush of the ink when the float and cup are pressed
down by the pen.
In figure 6, the cover is formed with a plate B³ to which the tube C is attached.
The space K above the plate B between it and the outer surface B₁ forms an overflow
chamber to receive any ink that may overflow the top of the tube C so that no ink
can find its way to the outside of the inkstand, not even if the stand be upset, except
what might at the time be contained in the cup J. A rubber disc B' may be used
with this form of stand, if desired.
Having now particularly described and ascertained the nature of the said -
invention and in what manner the same is to be performed, I declare that what [
claim is
1. An inkstand provided with a cover, combined with a tube fitted in the cover, a
float placed in the tube, and a dip-funnel or cup, as described.
