Improvements in and connected with Stoppers and Covers for Ink
Bottles and the like.
I, LEVI HOFFMAN THOMAS, of 6, St. George's House, 6 to 8, Eastcheap, London,
Doctor of Medicine, do hereby declare the nature of this invention to be as
follows:
This invention has reference to improvements in connection with stoppers and
covers for use upon ink bottles, the central lower portion of which is constructed
in accordance with the Specification of my Patent No. 11552/95. The object of
the present invention being to produce a stopper or cover which can be readily
removed from the ink bottle of vessel for the purpose of refilling or cleansing
the same, but when it is in position upon the vessel to effect a complete scaling or
the contents of the bottle so as to prevent evaporation and leakage, and to obviate
spilling when the bottle is overturned.
In carrying my invention into effect when constructing a cap or cover for use
upon a bottle with a plain upper or annular head or neck, I provide an inner
elastic tube or nipple, in which I form one or more air openings near its upper
end while its lower end I slit or cut to form an automatic valve in the manner
described in the Specification of my Patent No. 11552/95. The upper end of
this inner elastic tube or nipple I make to fit the interior or open end of the
neck of the bottle by providing upon the inner portion of the nipple a projecting
bead like rim or flange, into which or under which a projecting lip or grooved
end of a cap may enter so as to press outwards the rubber or elastic material
against the inner surface of the bottle neck.
I provide a ring or cap to secure the elastic tube in position making the inner
portion of the cap with an opening through which the pen may pass to withdraw
ink from the well, and I form around the inner lower end of the opening of the
cap an annular space to form an air escape from the air holes communicating
with the ink well and also to receive and secure any small portion of ink which
may escape into the inner portion of the tube or nipple so that when the bottle
or vessel is capsized the ink within the tube or nipple falls within the annular
space around the cap and thus its escape is prevented. I provide upon the
Hange of the cap a groove or bead to receive the like grooved upper end of the
nipple so that when the cap is placed in position it securely carries the nipple
upon the bead, while, the yielding nature of the nipple enables an air tight
contact to be made upon the outer surface of the nipple against the inner surface
I form a
of the bottle thus hermetically sealing the contents of the bottle.
head or beaded shoulder upon the upper surface of the cap to enable it to rest
upon its under side upon the upper edge of the neck of the bottle, but to project
slightly over such neck in order to enable a grip to be obtained when it is
desired to remove the cap and nipple from the bottle for recharging or cleaning
purposes.
I may remove the cap and nipple from the bottle by inserting a knife blade
or the like, under the projecting cap head or I roughen or otherwise shape the

page_text: head of the cap to enable a gripping contact to be made with the fingers so as
to secure easy withdrawal.
To admit of the escape of air from the interior of the bottle when the nipple
and its cap are being pressed down I provide one or more holes near the upper
edge of the nipple so as to allow the air to escape through the same from the
interior of the well of the bottle into the inner cavity formed by the annular
space between the lower end of the cap and the interior of the nipple, and after
the air has escaped such holes are closed against the interior of the ink bottle neck
when the cap is in its lower or closed position.
.
When applying my removable cap to a bottle or vessel specially constructed
to receive the same I form upon the neck of the bottle an outwardly projecting
rim or head, and I arrange my improved elastic tube or nipple with its valve
like end within the opening of the bottle so that its outer surface rests against
the inner portion of the neck of the bottle while its upper end I form as a flange
or rim to rest upon the upper edge of the neck of the bottle.
To secure this nipple in position and provide the annular space for any escaping
ink to enter I employ a cap or ring of rubber or other elastic material with its
inner portion provided with a conical like recess having an opening through the
same for the pen to pass through: while its upper portion is formed as a ring
like flange which rests upon the upper flange like rim of the nipple thus pressing.
it upon the outer rim of the bottle neck while the outer edge of the retaining
cap I form with an inner projecting rim or bead which enters under a like
projecting outer bead formed upon the neck of the bottle. To secure this
retaining cap to the nipple and to seal the same to the neck of the bottle I employ
a ring or collar which I pass over the outer edge of the retaining cap so as to
press the elastic material of the retaining cap against the neck of the bottle, the
securing ring or collar being provided with an upper flange to rest upon the
upper surface of the retaining cap.
I modify the form of my securing ring or collar and the arrangement and
shape of the retaining cap and nipple to suit the type and size of bottle or vessel
neck to which my improved stopper or cap is to be applied.

Improvements in and connected with Stoppers and Covers for Ink
Bottles and the like.
I, LEVI HOFFMAN THOMAS, Doctor of Medicine, of 6, St. George's House
6 to 8, Eastcheap, London, E.C., 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 has reference to improvements in connection with stoppers
and covers for use upon ink bottles and the like the central lower portion of
which is constructed in accordance with the Specification of my. Patent
No. 11552/95. The object of the present invention being to produce a stopper
or cover which can be readily removed from the ink bottle or vessel for the
purpose of refilling or cleansing the same, but when it is in a position upon the

page_text: vessel to effect a complete sealing of the contents of the bottle so as to prevent
evaporation and leakage, and to obviate spilling when the bottle is overturned.
In the accompanying sheet of explanatory drawings Figure 1 is a sectional
elevation and Fig. 2 is a plan of my improved stopper when constructed for
attachment to an crdinary open mouth bottle.
Figures 3 and 4 are similar views of my improved stopper when applied to a
bottle the neck or mouth of which has been specially formed to receive the
improved stopper.
In carrying my invention into effect when constructing a cap or cover for use
upon a bottle with a plain upper or annular head or neck as shown in Figure 1, I
provide an inner elastic tube or nipple a in which I form one or more air
openings 6 near its upper end while its lower end I slit or cut to form an automatiz
valve in the manner described in the Specification of my l'atent No. 11552/95.
The upper end of this inner elastic tube or nipple I make to fit the interior or
open end of the neck of the bottle by providing upon the inner portion of the
nipple a projecting bead like rim or Hange g, into which or under which a
rojecting lip or grooved end of a cap d may enter so as to press outwards the
rubber or elastic material against the inner surface of the bottle neck.
I provide a ring or cap d to secure the elastic tube or nipple in position
making the inner portion of the cap with an opening e through which the pen
may pass to withdraw ink from the well, and I form around the inner lower end
of the opening of the cap an annular space f to form an air escape from the air
holes communicating with the ink well and also to receive and secure any
small portion of ink which may escape into the inner portion of the tube or
nipple through the valve e so that when the bottle or vessel is capsized the ink
within the tube or nipple falls within the annular space f around the cap and
thus its escape is prevented. I provide upon the flange of the cap a groove or
bead to receive the like grooved upper end g of the nipple so that when the
cap is placed in position it securely carries the nipple upon the bead, while the
yielding nature of the material of the nipple enables an air tight contact to
be made upon, the outer surface of the nipple against the inner surface of

head or beaded shoulder & upon the upper surface of the cap to enable it to rest
upon its under side when placed upon the upper edge of the neck of the bottle,
but to project slightly over such neck in order to enable a grip to be obtained
when it is desired to remove the cap and nipple from the bottle for recharging
or cleaning purposes.
I may remove the cap and nipple from the bottle by inserting a knife blade or
the like under the projecting cap head k or I roughen or otherwise shape the
head of the cap to enable a gripping contact to be made with the fingers so as to
secure easy withdrawal.
To admit of the escape of air from the interior of the bottle when the nipple
and its cap are being pressed down I provide one or more holes near the upper
edge of the nipple so as to allow the air to escape through the same from the
interior of the well of the bottle into the inner cavity f formed by annular space
between the lower end of the cap and the interior of the nipple, and after the air
has escaped such holes are automatically closed by atmospheric pressure against
the interior of the ink bottle neck when the cap is in its normal position.
When applying my removable cap to a bottle or vessel specially constructed
to receive the same as shown in Fig. 3 I form upon the neck of the bottle an
outwardly projecting rim or bead and I arrange my improved elastic tube or
nipple with its valve like end within the opening of the bottle so that its outer
surface rests against the inner portion of the neck of the bottle while its upper
end I form as a flange or rim to rest upon the upper edge of the neck of the
bottle.
To secure this nipple in position and provide the annular space f for any
escaping ink to enter I employ a cap or ring of rubber or other clastic material m

page_text: with its inner portion provided with a conical like recess having an opening
through the same for the pen to pass through while its upper portion is formed
as a ring like flange which rests upon the upper flange like rim of the nipple
thus pressing it upon the outer rim of the bottle neck while the outer edge of
the retaining cap I form with an inner projecting rim or bead o which enters
under a like projecting outer bead p formed upon the neck of the bottle.
To secure this retaining cap to the nipple and to seal the same to the neck of
the bottle I employ a ring or collar which I pass over the outer edge of the
retaining cap m so as to press the elastic material of the retaining cap under the
lipp and against the neck of the bottle, the securing ring or collar being provided
with an upper flange or inwardly projecting collar to rest upon the upper surface
of the retaining cap.
When constructing a simpler form of removable cover I sometimes dispense
with the outer binding collar n by making the outer surface of m strong and firm
enough for engaging alone with the neck or head of the bottle.
I modify the form of my securing ring or collar and the arrangement and
shape of the retaining cap and nipple to suit the type and size of bottle or vessel
neck to which my improved stopper or cap is to be applied, and when arranging
my bottle for use with gum or similar material I provide an open hole instead of
the before-mentioned slits in the bottom of the nipple through which the brush
may pass.
Having now particularly described & 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 removable stopper attachment for inkstands, and the like, comprising
a ring or cap, and an elastic tube or nipple provided with one or more air
openings near its upper end and slitted at its lower end to form an automatic
valve substantially as herein before described.
2. A removable stopper attachment for inkstands and the like, comprising a
ring or cap provided with a dependent annular flange bevelled on its outer
surface, and having an annular collar extending below said flange in combination
with an elastic tube or nipple engaging with said flange, and provided with one
or more air openings such tube and collar constituting an annular air space with
which the air openings in the tube communicate, and from which air escapes
below the bevelled flange, substantially as hereinbefore described and as illus-
trated in the accompanying drawings.
3. A removable stopper attachment for inkstands and the like, comprising
an elastic cap having an inner annular bevelled flange which projects below its
outer surface and an outer beaded collar or rim for engaging with or clipping
on to the neck of the bottle or vessel, in combination with an inner depending
elastic tube or nipple, and an outer retaining or securing collar or ring which
holds the cap and its depending tube in position upon the bottle neck, sub-
stantially as herein before described and as illustrated in Figure 3 of the accom-
panying drawings.
