Improvements in Ink Pots or Ink Holders.
I, SAMUEL STIRLING, of Brighton Street, Heckmondwike, in the County of York,
Assurance Agent, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in ink pots or ink holders, and its object
is to provide a self regulating pen dip supplied with filtered ink.
For this purpose I employ a holder of the bird fountain type in which the
height of the passage from the main reservoir to the pen dipping cup or vessel
regulates the depth or height of the ink in the latter and so regulates the depth
of the dip of the pen.
The vessel is fitted with a hermetically closable screw stopper and a suitable
filtering medium is introduced in such a manner that the ink can only gradually
pass to the dipping cup and consequently does not overflow there when supplied
to the main reservoir.

Improvements in Ink Pots or Ink Holders.
I, SAMUEL STIRLING, of Brighton Street, Heckmondwike, in the County of York,
Assurance Agent, 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 relates to improvements in ink pots or ink holders, and its object
is to provide a self regulating pen dip supplied with filtered ink.
For this purpose I employ a holder of the bird fountain type in which the
height of the passage from the main reservoir to the pen dipping cup or vessel
regulating the depth or height of the ink in the latter and so regulates the depth
of the dip of the pen.
The vessel is fitted with a hermetically closable screw or other stopper and a
suitable filtering medium is introduced in such a manner that the ink can only
gradually pass to the dipping cup and consequently does not overflow there when
supplied to the main reservoir.
To fully describe my invention reference is made to the accompanying sheet of
drawings forming a part of this specification, in which similar letters of reference
indicate corresponding parts in each of the figures.

page_text: Figure 1, represents a side elevation of my improved ink pot.
Figure 2, is a plan view, and Figure 3, is a section of the same on the broken
line a, b.
Figure 4, is a separate sectional view of the base piece hereinafter referred to.
The ink reservoir A is made of glass, earthenware or any suitable metal and the
filling aperture B is closed by a stopper C fitting therein. An aperture D is made
in the bottom of the reservoir in which a finely perforated disc E, to form a filter,
is fixed, or a disc of porous unglazed earthenware may be used. In either case
the disc is preferably surrounded by an india-rubber ring F and is pressed into
the aperture sufficiently tight to retain it in position.
The bottom of the reservoir is cemented into the recess G formed in the top
of the base piece H and rests upon the shoulder J therein. The ink percolates
through the disc E into the recess G and flows by the passage K into the dipping
cup L, formed in H, and rises therein until it reaches above the level of the
bottom of the aperture D and thereby cutting off the supply of air stops the further
flow until the ink in L again falls below the level of the aperture and permits
the air to pass.
A hinged cap or cover N is preferably provided to close N when not in use as
shown in Figure 1.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
The combination with an ink pot of the type specified of a filtering medium
between the ink reservoir and the dipping cup, substantially as herein shown and
described.
Dated this 18th day of January 1899.
