Improvements in Inkstands.
1, ARTHUR JOSEPH INGRAHAM, a citizen of the United States, residing at
1406 South Penn Square, in the City of Philadelphia, in the County of
Philadelphia, and State of Pennsylvania, Manufacturer, do hereby declare the
nature of my invention for IMPROVEMENTS IN INKSTANDS, 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 certain novel features in an inkstand adapted for the
ready delivery of ink for use.
The principal object of the invention is to provide an inkstand having delicate or
sensitive means applied thereto for the compression of the air therein so that by a
slight pressure of the pen against the delivery tube thereof, the fluid will be
presented for use.
The nature and characteristic features of the invention will be more fully
understood from the following Specification taken in connection with the accom-
panying drawings forming part hereof; and in which
Figure 1, is a vertical central section through an inkstand embodying the
particular features of my invention; and
Fig. 2, is a modified form of the same.
Referring to the drawings a, is the inkstand made of glass or other suitable
material. b, is a cap or cover of suitable construction secured in any convenient
manner to the threaded exterior portion of the stand a. On the upper edge of the
inkstand a, may be mounted a gasket c, of rubber or other preferred material.
Between the cap or cover b, and top of the inkstand a, is interposed a disc d, of
rubber or other flexible or pliable material. The cap or cover b, and disc d, are
provided with central apertures through which is inserted a tube e, composed of
rubber, celluloid or other material and having formed in the wall and extending
through said tube at the lower extremital portion thereof air and fluid apertures e
The upper portion of said tube e, is provided. with a collar e² and with a funnel-
shaped extremity e³. The portion of the tube e, having the enlargement or collar e²,
is provided in the interior with a partition, forming a valve adapted to regulate
the quantity of ink or fluid permitted to flow through said tube e, to the funnel-
shaped upper extremity thereof, for use. Mounted on the tube e, and abutting
against the lower end of the funnel-shaped portion thereof between the cap or
cover b, and the disc d, is arranged a bent spring metal piece a, such for example
as is shown in Fig. 1, for returning the tube e, to its normal position after the
pressure exerted at the funnel-shaped extremity to cause the ink or fluid to rise
therein for use, is released. About midway of the tube e, are formed lugs h, having
sloping surfaces and rounded upper corners and over which lugs is introduced a
tubular washer i, formed of clastic material for holding the disc d, and spring metal
piece g, in proper position to the tube e, for ensuring the best results in the
practice of the invention. The lugs are of such construction as a part of the
integral formation of the tube e, as that the tubular washer i, may be readily
detached therefrom by simply removing the cap or cover b, for detaching the other
parts connected with said tube.
The construction and arrangement of the inkstand illustrated in Fig. 2, are the
same as that shown in Fig. 1, with the exception that instead of a bent spring
metal piece g, being employed, a spiral spring is substituted and coiled around the
tube e, in such manner as that one extremity will be in engagement with said tube
and the other extremity will be in engagement with the disc d, the purpose of
which is to return the tube e, to its normal position after the pressure exerted
thereon at the funnel-shaped extremity, is released.

page_text: To fill the inkstand a, the cap or cover, is removed and the fluid poured into
the same in the ordinary manner. The cap or cover is then restored to the position
shown in the drawings and by a slight pressure exerted by means of the pen at the
funnel-shaped extremity of the tube e, the fluid is brought to a position in the
funnel for use. The valve provided on the interior of the enlarged portion e³, of
the tube regulating the flow of the fluid through said tube for use, at the exposed
end thereof.
Having now particularly described and ascertained the nature of the inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The inkstand constructed and arranged substantially in the manner shown and
described.
2. In an inkstand provided with a cap or cover, a spring actuating device and a
flexible disc and both interposed between the cap or cover and top of the stand, of
a funnel-shaped tube extending into said stand and provided with an integral collar
having a valve therein and apertures in the lower part of said tube, substantially as
and for the purposes described.
3. In an inkstand provided with a cap or cover and an interposed flexible disc,
of a tube extending into said stand having a valve formed integral therewith and
said tube provided with lugs for maintaining a washer in position adjacent to said
disc, substantially as and for the purposes described.
4. An inkstand provided with a cap or cover, a gasket, a flexible disc, and a
delivery tube supported by a spring and extending through the cap or cover and
disc into the chamber of the inkstand and said tube having a valve formed integral
therewith for regulating the quantity of fluid presented at the delivery end thereof,
substantially as and for the purposes described.
Dated this 13th day of January 1891.

INGRAHAM.
