Ink Bottles or Stands.
We, ALBERT EDWARD DAIN, Engineer, of the City of Pittsburgh, County of
Allegheny and State of Pennsylvania, United States of America, JOHN H. RONEY,
Attorney at Law, of No. 127 Fifth Avenue said City, County, State and Country,
and JOHN Q. EVERSON, Insurance Agent, of said City, County, State and Country,
do hereby declare the nature of our invention for INK BOTTLES OR STANDS, 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 our invention is to produce an Ink Bottle of the fountain type
adapted to exclude dust, dirt and other foreign substances, thereby keeping the ink
clear and fresh, and by keeping the ink wholly free from exposure to the atmosphere,
preventing evaporation thereof.
We will now more specifically describe our invention, reference being had to the
drawings hereto attached, in which
Fig. 1 indicates a vertical central section of our Ink Bottle.
Figs. 2 and 3 show respectively perspective views of the tube and elastic rubber
thimble.
Figs. 4, 5 and 6 are sectional views of three different forms or modifications of the
rubber thimble.
In said drawings A is the ink bottle or well preferably formed of glass, the neck
thereof being provided with an annular groove a, as shown in Fig. 1; B is an elastic
rubber thimble, the lower inside circumference of which is provided with the beads b
and to fit into said groove and over the upper edge of the neck of the bottle
respectively; or said thimble may be preferably formed with the lower bead only and
flared at the bottom as shown in Figs. 2, 3 and 4, and is preferably of greater diameter
at its lower extremity than at its upper extremity, as shown in the drawings; said
thimble is formed of rubber of sufficient rigidity to maintain the same, and the
tube F, formed of hard rubber or other suitable material, which projects in said
bottle in an upright position upon the neck of the bottle or well. The upper inner
side of said thimble is provided with a bead e, which engages in a groove d upon the
upper ontside surface of the bowl of said tube, said thimble being retained on said
tube by its elasticity; the hard rubber collar or ring C, which surrounds said thimble
at the point of its attachment to the tube assisting also to maintain and permanently
secure said thimble thereon, or said collar or ring may be preferably provided with an
internal thread to engage a thread upon the outside surface of the flared mouth of the
tube, as shown in Figs. 1 and 3 of the drawings, and may also be preferably provided
with a flange e, as shown in said Figs. 1 and 3 for the purpose of limiting and
regulating the downward movement or dip of said tube, and thereby regulating the
quantity of liquid in the bowl of said tube. In case the latter form of collar or ring
be used instead of the plain ring shown in Fig. 2 it must not impinge against or press
upon the thimble, but must be permitted to move upon the threads freely to regulate
the quantity of liquid as heretofore specified; when the plain ring shown in Fig. 2
instead of the flanged ring is used, the dip of said tube and the quantity of liquid in
the bowl thereof is regulated by the length of said tube. D) is a curved or concave
cap formed of hard rubber or other suitable material, and is provided with an orifice
through which the upper end of the tube projects and is permitted to move freely
therein, the sides of said orifice limiting the lateral movement of said tube and pre-
venting the ink in the bowl thereof slopping over. In the inside of the bowl or
flared mouth of said tube, as near the periphery as possible, an orifice is made through
the same into the air chamber formed by the thimble on the neck of the bottle or
well for the reception of the plug E, which is permitted to remain therein at all times,
removing it only when it is desirable to fill the bottle or well, which can be done when

page_text: said plug is removed by pouring the liquid into said bottle or well through said tube,
thus avoiding the necessity of removing the cap and thimble and danger of soiling
the hands in doing'so; said tube is also provided with a small pin finserted trans-
versely through the same at or near the base of the bowl or flared mouth of said tube
for the purpose of breaking the force of the liquid in 'ascending through said tube,
preventing squirting and enabling the liquid to flow gently into the mouth of said
tube when the same is depressed by thrusting a pen or otherwise applying force upon
the elastic thimble, thereby depressing the same and compressing the air in said bottle,
whereby liquid is forced up said tube into the bowl thereof, and by withdrawing, the
pen or otherwise removing the force, the elastic thimble resuming its former position
carries the tube upward, removes the pressure upon the contents of the bottle, and
permits the liquid forced into the bowl of said tube to recede into said bottle. Aside
from keeping the ink free from dust, &c., and preventing evaporation of the same, the
user thereof is not compelled to thrust the pen perpendicularly into the bowl of the
tube, but may insert the pen at an angle, the orifice in the hard rubber cap being
large enough to permit the deflection of the flexible neck of the thimble to either side
to admit of this.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner, the same is to be performed, we declare that what. we
claim is :
1. The combination of an ink well or bottle, a vertical internal tube F fitted therein
and having a rigid flared bowl, an elastic thimble secured at its ends to the mouth of
the ink well, and the flared bowl of the internal tube, a rigid external cap fitted
tightly over said elastic thimble at its point of attachment to the ink well, and having
an orifice in the upper end of the same, through which said internal tube passes, and
an adjustable ring carried by the flared bowl of the internal tube and movable freely
within the orifice of the rigid external cap, which cap operates to limit the play of
the adjustable ring and the internal tube to which it is attached as and for the purpose
described.
2. The combination of a bottle or receptacle, an internal tube provided with a
Hared rigid bowl, an elastic thimble attached to said bottle or receptacle, and the bow!
of the internal tube, an external ring carried by the internal tube and connected
thereto so as to be moved up or down thereon, and a fixed external cap surrounding
the elastic thimble and arranged in the path of the external ring to limit the down-
ward movement of said ring and the internal tube to which the ring is attached,
substantially as and for the purpose described.
3. The combination of an ink well or receptacle, an internal tube F provided with
a transverse pin at an intermediate point of its length and having the flared bowl
at its upper end, said bowl having a filling aperture and a removable, plug, an
adjustable ring or band screwed on the flared bowl of the internal tube, an elastic
thimble attached to the ink well and the bowl of the tube, and a rigid cap D which
incloses the elastic thimble and receives the lower end of the adjustable band ór ring,
substantially as described.
