I, DAVID MASON, Civil Engineer, of 212 Saint Vincent Street, Glasgow, in the
County of Lanark, Scotland, Patent Agent, do hereby declare the nature of this
invention to be as follows:-
This Invention relates to that class of Penholders having an ink reservoir contained
within the holder from which ink is supplied to the pen during use.
The apparatus as constructed according to the Invention comprises a metal case
serving to hold the ink and screwed at top on which fits a lid over an air-hole.
Another metal tube which at its top part is made to be screwed into bottom of former
tube has towards the lower part a niche or hole into which a sponge is placed and
terminates in a bent orifice through which the ink is sent to pen, and is encased in a
caout-chouc pouch or cover the orifice projecting therethrough. Over last said case
and pouch is fitted another tube having a part cut out to correspond with hole in
inner case, the pouch being between them, by pressing which by thumb the sponge is
pressed and sends ink to the pen at base of outer case. The whole is shut into an
outside tube when not in use, which in use is mounted on top to lengthen the
holder.

page_text: I, DAVID MASON Civil Engineer of 212 Saint Vincent Street, Glasgow in the
County of Lanark, Scotland, Patent 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, reference being had to
annexed Drawings: :-
The said Invention relates to that class of Penholders having an ink reservoir
contained within the holder, from which ink is supplied to the pen during use.
The apparatus as constructed according to our Invention comprises a metal case a
serving to hold the ink, and fitted with a stopper of caoutchoue, cork or other
suitable material, having an outer end a cap of metal corresponding with ease.
Another metal tube b which at its top part is enlarged and soldered into bottom of former
tube a has a niche or hole formed therein into which a sponge Fig. 4 is placed; said
tube terminates in a narrower and bent orifice d through which the ink is sent to
pen. Over the niched part of tube is drawn a cylindrical tube of caontehone /
which encases said tube and sponge,
Over said tale with contehone cover or
Fig. 5 encircling same, is litt mother ease, tube or ferrule Fig. 3 having

the ten wit
short otherwise may be slipped on top of stopper and case a thus lengthening it.
The apparatus is operated as follows. The sponge Fig. 4 is put into tube through
hole c; the caoutchouc cover being put over both, care being taken to keep the sponge
well in its place; the whole is then covered with movable ferrule i Fig. 3, the holes e
and e being opposite each other. The case a is filled with clear ink of best quality;
the stopper being put into top. The pen is now fitted into the holder fin such a
manner that the hole in the pen is brought into contact with the orifice d of tube b.
This latter point is essential and it is for bringing the encloseure into the exact place
of the pen at the desired point that the ferrule i is movable and must be able to glide
on the upper part of tube h. The thumb being placed on the caoutchoue diaphragm
the ink in the sponge by three or four presses thereof will flow under the pen through
orifice d. If it be found that the ink goes down too slowly, it is sufficient to allow air
to enter by stopper k. The ink once having descended and the sponge imbibed it, a
light and natural press of the thumb will suffice to nourish the pen. As soon as the
pressure of the thumb ceases, a sort of aspiration is caused which dries the pen, thus
constituting a great advantage. The sponge serves as a filter, thus keeping the ink
pure and preventing the dirtyness produced heretofore by existing systems. If the
last drop of ink should dry in at end of bent tube, it may be removed with a pin, and

page_text: if through long use the sponge gets soiled it has but to be replaced, the apparatus
being taken apart.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is,
1st. The construction, arrangement and combination of parts of a reservoir
penholder containing a sponge, substantially as hereinbefore described and shown.
2nd. The application and use of a sponge which can be pressed by a flexible
diaphragm h, substantially as and for the purpose described and shown.
