PROVISIONAL SPECIFICATION.
A Reservoir Inkstand, applicable also for Containing other Liquids.
I WILLIAM POPPLEWELL MASON, of 12 Golden Lane in the City of London,
Commercial Traveller do hereby declare the nature of this invention to be as
follows:-
My invention relates to what may be termed a fountain reservoir for containing
and supplying liquid in small quantities as required, the particular application for
which the invention was designed being for supplying ink for working purposes to
a small dipping cup, the special object being to protect the bulk of the ink from
the evaporative and contaminating influence of the air.
As applied to the purposes of an ink.stand, it consists of an ink reservoir closed
at top by a flexible diaphragm protected by a removable cap and provided with an
air passage and opening at bottom into an ascending channel rising to about the
level of the top of the said reservoir and terminating in a minute swan-neck nozzle
immediately over a dipping cup into which as much ink as may be required for
temporary purposes is discharged from said nozzle by gentle pressure on the flexible
diaphragm.

COMPLETE SPECIFICATION.
A Reservoir Inkstand, applicable also for Containing other Liquids.
I, WILLIAM POPPLEWELL MASON of 12, Golden Lane, in the City of London,
Commercial Traveller, 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:--
My invention relates to what may be termed a fountain reservoir for containing
liquid and supplying it in small quantities as required, particularly for supplying
ink for writing purposes to a small dipping cup, the special object being to
protect the bulk of the ink from the evaporative and contaminating influence of
the air.
As applied to the purposes of an ink-stand, it consists of an ink reservoir
provided with a syphon-shaped or swan-neck outlet tube or duct rising from
near the bottom of the reservoir to a point above the highest level of the
liquid in the reservoir and terminating in a short nozzle immediately over a
dipping cup, the said outlet tube being in the form of a reversed syphon, that is to
say the longer leg being within the reservoir, so that the contents of the reservoir
cannot under any circumstances run off spontaneously but may be discharged in
small quantities as required, by slightly compressing the air in the upper part of
the reservoir. This compression may be obtained either by pressing the palm of
the hand directly upon the mouth of the reservoir or through the medium of a
flexible diaphragm, cap, or ball, applied over or in the mouth of the reservoir.
Reference is to be had to the accompanying drawings, forming part of this
Specification, wherein
Figure 1 is a perspective elevation and Figure 2 a vertical section of an ink-
stand from which the discharge of the ink is effected by the pressure of the hand
applied upon the mouth of the reservoir.

page_text: Figures 3, 4, and 5, are part sectional views of a similar inkstand, illustrating
respectively the application of a flexible cap diaphragm and ball to the mouth of
the reservoir.
The same letters of reference indicate similar parts in all the figures.
A is the reservoir (made of earthenware glass, vulcanite, or other suitable
material) provided with a mouth a which may be closed by a removable cover or
stopper, as in Figures 1 and 2, and with a discharge tube B rising within the
reservoir from near the bottom thereof to a bend about level with the mouth a
and terminating in a short downward nozzle over a dipping cup C. By removing
the cover or stopper D and repeatedly pressing the palm of the hand on the mouth a,
the contents may be ejected through the tube B.
In Figures 3 and 4 a tubular stopper E is fitted in the mouth a to which is
affixed, in Figure 3, a hemispherical cap, and, in Figure 4, a diaphragm F, of india
rubber, provided with an air-hole f to permit the ingress of air on the removal of
the finger by which pressure is applied to the cap F.
In Figure 5 an ordinary india-rubber ball having air holes ff at top and bottom
simply rests in the mouth of the reservoir A.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
1. In an inkstand or other fluid reservoir, the combination, with the reservoir
(provided with a mouth or aperture at the upper part) of a discharge tube or duct
rising from near the bottom of the reservoir to a swan-neck bend at the upper part
of the reservoir and terminating in a downward nozzle, above a dipping cup or other
receiver, substantially as and for the purpose specified.
2. The combination, with the reservoir having the swan-neck discharge tube or
duct as described, of a flexible diaphragm cap or ball applied to the mouth of the
reservoir, as and for the purpose described.
