and authority, 'that we, the said Marie Melanie. D'Hervilly Hahneman and
Henry Petitpierre, our exors, admiors, and assigns, or such others as we, the
said Marie Melanie D'Harvilly Hahnemann and Henry Petitpierre, our
exors, "admors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and "lawfully might make use, exercise, and vend, within. England,
Wales, and the Town of Berwick-upon-Tweed? our Invention of "IMPROVE-
MENTS IN INSTRUMENTS FOR WRITING;" in which said Letters, Patent is
contained a proviso that we, the said Marie Melanie D'Hervilly Hahnemann
and Henry Petitpierre, or one of us, shill cause a particular description of the
nature of the nature of our said Invention,' and in what manner the same
is to be performed, by an instrument in writing ninder our hands and seals,
or under the hand and seal of one of us, to be inrolled in Her said Majesty's

page_text: High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear. .
NOW KNOW YE, that in compliance with the said proviso, we, the said
Mario Melanie D'Hervilly Hahnemann and Henry Petit, do hereby declare
that the nature of our said Invention, and the manner in which the same is
to be performed, are fully described and ascertained in and by the following
statement thereof, reference being had to the Drawing hereunto annexed,
and to the figures and letters marked thereon, that is to say:-
The Invention relates to improvements in the construction of that kind of
instruments to be used for writing known as fountain pens, that is, pens which
contain within themselves a reservoir of ink; but, in order that the Invention
may be clearly understood, we would proceed to describe the Drawing hero-
unto annexed; and we would remark, that we have used in the different
Figures similar numbers to represent the same parts.
Figure 1 shows an external view of an instrument to be used for writing;
Figure 2, another view, showing part in section; Figure 8 shows a cover, to
put on when the instrument is not required to be used; and Figure 4 shows
some of the parts in detail.
8 is a small hollow
may
The number 1 shows the cover of the upper part of the instrument, in the
top of which cover is a recess, into which engraved stone may be inserted
when it is required to use it as a seal. In the inner part is another groove,
into which is fitted an elastic plug, by which the top is screwed on air tight.
2 is a chamber at the upper part of the instrument.
scrow or cock, by turning which atmospheric air is allowed to pass into the
inner part of the instrument. 4 is the tube of the instrument, which be
made of gold, silver, porcelain, or other suitable material. 5 is a piece of
copper or other suitable material, which is placed at the lower end of the
instrument, and acts as a stopper or cork. In the centre of this piece is a
hole, through which is inserted a screwed cock, which has also a hole through
its centre for the passage of ink. 6 is a screw cock, having on its exterior
four teeth, which indicate the flowing of the ink. 7 is a small piece attached
to the tube, for the purpose of conveying the ink to the pen. 8 is a regulating
screw, to adjust the position of the pen. 9 is a case to put over the pen when
it is not required to be used. 10 is the pen. 11 is a lever carrying a spring,
by which it is moved. 12 is a sunk plate, which opens and shuts by means of
the movement of the lever 11, and which gives passage to the ink. This plate
is fixed by a screw to the inner part of the tube. 13 is a small flat-headed
screw placed upon the small lever 11, by which the flow of the ink may be
adjusted. This instrument is used in the following manner:-The ink is to be

page_text: introduced at the upper part of the chamber 2 by removing the cover 1.
During this introduction the cocks 8 and 6 are shut. When the tube 4 is
sufficiently fed the cover 1 is put on the chamber 2, then, by opening the
cocks 8 and 6 the ink flows by the hole of the piece 5 along the inner part of
the pen for writing.
Having thus described the nature of the Invention, and the manner of
performing the same, we would have it understood that we do not confine
ourselves to the precise details, so long as the character of the Invention be
retained. But what we claim is, the mode of combining the instrument with
a cover shutting hermetically the top of the reservoir tube of ink, and with
two orifices or cocks, the one placed at the upper part of the instrument, for
allowing atmospheric air to pass into the reservoir tube, and the other placed
at the lower part of the same tube, for distributing the ink to the pen.
In witness whereof, we, the said Marie Melanie D'Hervilly Hahnemann
and Henry Petitpierre, have hereunto set our hands and seals, this
Seventh day of October, in the year of our Lord One thousand eight
hundred and forty-seven.
