PROVISIONAL SPECIFICATION.
Improvements in Ink Bottles and Ink Stands.
We, GUSTAVUS ROGER WEED, Salesman, and ARTHUR MOULTON MITCHELL,
Salesman, both of Orange, in the County of Essex, and State of New Jersey,
United States of America, do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to provide an attachment for ink bottles and ink
stands which will force up a small quantity of ink for use when a slight pressure is
applied by the pen and which will practically seal the bottle so that evaporation
cannot take place, thus permitting of keeping the ink in usable condition until it is
exhausted.
The invention consists in a perforated stopper provided with a tube having at the
upper end a flexible air chamber and a funnel extending through the stopper and
provided with a flexible tube of sufficient length to reach to the bottom of the ink
bottle.
The stopper is preferably made of soft rubber. It is bored axially and in it is
inserted a tube having at the upper end thereof a funnel-shaped chamber closed at
the top by a flexible diaphragm, furnished with a rim stretched over the upper
edges of the walls of the chamber, and at its centre it has an aperture which is
reinforced or thickened around the edges to cause it to press firmly on a second
tube inserted in the diaphragm and extending through the first tube. The upper
end of the inner tube terminates in a funnel, and to its lower end is attached a
flexible tube of sufficient length to reach the bottom of the bottle. "When the
funnel is pressed by the pen the diaphragm is depressed, thus compressing the air
in the chamber and in the ink bottle thereby forcing upwardly a sufficient amount
of ink to partly fill the funnel and charge the pen. When the funnel is released
the diaphragm regains its original position by means of its own elasticity, and
in so doing creates a partial vacuum in the chamber and in the bottle and thus
causes air to be drawn in through the tubes, and through the body of ink contained
in the bottle, thus replacing with air the ink removed by the pen.
In a modification, the chamber is made wholly of elastic material and its upper
and lower sides are perforated, the lower side receiving the tube which extends
into the perforated stopper while the upper side receives the tube which projects
downwardly from the funnel. The outer tube in this case is enlarged in diameter
and extends upwardly in the chamber to form a stop for limiting the compression
of the elastic chamber. When the funnel is pressed by the application of a pen the
air is forced from the chamber through the space around the tube into the bottle,
as in the other case.

We, GUSTAVUS ROGER WEED, Salesman, and ARTHUR MOULTON MITCHELL,
Salesman, both of Orange in the County of Essex, and State of New Jersey,
United States of America, 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 :-
Reference is to be had to the accompanying drawings, forming part of this
Specification, in which similar letters of reference indicate corresponding parts in
both the figures.
Figure 1 is a vertical transverse section of an ink bottle to which our improved
attachment has been applied; and Figure 2 is a vertical transverse section of a
modified form.
The object of our invention is to provide an attachment for ink bottles and ink
stands, which will force up a small quantity of ink for use, when a slight pressure is
applied by the pen, and which will practically seal the bottle so that evaporation
cannot take place, thus permitting of keeping the ink in usable condition until it is
exhausted.
The invention consists in a perforated stopper provided with a tube having at the
upper end a flexible air chamber, and a funnel inserted in the flexible air chamber,
extending through the stopper and provided with a flexible tube of sufficient
length to reach to the bottom of the ink bottle, all as will be hereinafter fully
described.
a,
.
To the neck of the ink bottle A, which is of ordinary form, is fitted a
stopper B, preferably made of soft rubber. The said stopper B is bored axially
and in it is inserted a tube C, having formed upon the upper end thereof a
funnel-shaped chamber closed at the top by the flexible diaphragm D, furnished
with a rim b, which is stretched over the upper edges of the chamber a and
provided at its centre with an aperture c which is reinforced or thickened around
the edges to cause it to press firmly on a tube d inserted in the diaphragm.and
extending through the tube C.
Upon the upper end of the tube d is formed a funnel E, and to its lower end is
attached a flexible tube e, of sufficient length to reach the bottom of the bottle A.
When the funnel E is pressed by the pen, the diaphragm D is depressed', thus
_compressing the air in the chamber a and in the ink bottle A, thereby forcing
upwardly, by the pressure of the air created within the bottle, a sufficient amount
of ink to partly fill the funnel and charge the pen. When the funnel E is released
by the removal of the pen, the diaphragm D regains its original position by means
of its own clasticity, and in so doing creates a partial vacuum in the chamber a and
in the bottle, and thus causes air to be drawn in through the tubes d, e, and
through the body of ink contained in the bottle, thus replacing with air the ink
removed by the pen.
In the modification shown in Figure 2, the chamber a' is made wholly of elastic
material, and its upper and lower sides are perforated, the lower side receiving the
tube C¹, which extends into the 'perforated stopper B₁, while the upper side
receives the tube d¹ projecting downwardly from the funnel E. The tube C¹ in
this case is enlarged in diameter and extends upwardly in the chamber a¹ to form
a stop for limiting the compression of the elastic chamber. When the funnel E' is
pressed by the pen, the air is forced from the chamber a¹ through the space around
the tube d' into the bottle as in the other case.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a stopper attachment for ink stands, the combination with a perforated
stopper, of a chamber furnished with a flexible top, a funnel inserted in the
flexible top, extending loosely through the perforation of the stopper and provided
with a flexible tube at the lower end thereof, substantially as described.
2. In a stopper attachment for ink bottles, the combination of the perforated
stopper B, the tube C extending through the stopper and provided at its upper end
with a chamber a, the diaphragm D, stretched over the chamber, the funnel E
provided with the tube d, inserted in the diaphragm D, and extending through the
tube c, and the flexible tube e attached to the lower end of the tube d, substantially
as described.
3. In a stopper attachment for ink stands, a flexible centrally apertured
diaphragm thickened or reinforced around the aperture thereof, substantially as
described.
4. An attachment for ink bottles, comprising the centrally apertured stopper B,
an air tube C entering said aperture to force air down into the bottle and provided
with a funnel shaped or flared upper end a, a flexible diaphragm D, provided with
a rim b, embracing the rim of the funnel shaped end a, and having a central
aperture provided with thickened walls, and the ink funnel E having an ink
tube d extending down through the aperture e and through the air tube C and of
less diameter than said air tube, substantially as set forth.
