I GEORGE MESSERVY of Mont Cantel Saint Helier, island of Jersey, of no profes
sion do hereby declare the nature of this invention to be as follows:-
The said pen mainly consists of two metal tubes of unequal sizes, one fitting into
the other so that they can be drawn out and returned into place with facility.
A nib of the ordinary pencil form having a very fine point with the smallest
practicable aperture in it is screwed on to one end of each of the tubes made tapering
to receive it.
The inner tube has a groove round its other end for the reception of packing or of a
waterproof ring in order to keep the inside air-tight.
The inner tube has also a small longitudinal groove to receive the end of a screw or
an indentation of the outer tube to prevent the said tubes from separating when being
drawn out..
Removable caps containing waterproof pads are adapted to the ends of the pen to
protect the points, but principally to prevent the ink from hardening in the apertures,
and by this means to keep the nibs moistened and in working order.
Both ends of the pen being alike it can be filled from either.
When the pen has to be filled take off one of the nibs, dip the then uncovered end
of tube in ink, keep it there whilst you draw out the other tube then turn it up and
force the tubes back into place, and finally put on the nib. The pen will then be
ready for use.
Should the pen remain for some time without being used, shake it a little before
removing the caps so as to disturb any sediment that may have accumulated in
the nibs.
F
When writing with one of the nibs the aperture in the other can be made to admit
the air to the inside of the pen by either removing or loosening the protecting cap.

page_text: Improvements in Reservoir Pens.
I GEORGE MESSERVY of Mont Cantel St. Helier, island of Jersey, of no profession,
do hereby declare the nature of my invention for IMPROVEMENTS IN RESERVOIR
PENS and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This pen mainly consists of two tubes (CD) of different diameters, inserted, and
made to move one inside of the other. Their difference of size allowing for the
insertion of packing between them to make their connexion air-tight.
A short piece of tubing I is fixed inside one end of the larger tube by means of an
intermediate ring, and made to project beyond it. The smaller tube, when in place,
projects equally at the other end. A screw-thread J is turned on these projections for
the reception of nibs of the ordinary pencil form (E) with very small apertures in the
points.
Four rings K are screwed on to the inner end of the small tube, at equal distances.
The two end spaces between them are filled with packing and the centre one acts as an
air chamber. These rings are made to move freely in the outer tube.
A ring, with a break in it (L) and the ends slightly apart, is screwed inside the other
end of the outer tube, to prevent its separating from the inner one, when that is being
drawn out.
To keep the inner tube from turning with the nib, when it is being screwed on, a
small stopper (M) is fixed on to it and occupies the open space between the ends of
the ring.
Removable caps (G) are adapted to the ends of the pen, in the inside of which caps,
are placed hollow india-rubber pads (N) to prevent the ink from hardening about the
apertures in the nibs, and to keep them in good working condition.
The open ends of these caps (0) are made of a slightly oval form, so that, the pressure
of finger and thumb on their longest diameter, allows them to slip on with ease. When
the pressure is removed, they hold on firmly to the round nibs. Small knobs indicate
to the touch, where the pressure has to be applied.
When a nib is opened for the admission of air, the cap can be kept on, but it must
be brought out a little, so that the inside pad may not stop the aperture.
Inside each nib is placed a doubled up needle (F) with one end brought to a fine
point. The other end is twisted around it, and turned into a spiral spring. The
screwing on, and unscrewing of the nib, compresses this spring against the end of the
tube, or relaxes it, and thus the needle point is propelled and withdrawn and made to
close and open the aperture in the nib.
When the pen has to be filled take off one of the nibs, dip the then uncovered end
of tube in ink (P) keep it there whilst you draw out the other tube, then turn it up,
and force the tube back slowly into place. You will then put on the nib.
For desk use, the inner tube had better be left drawn out.
The filling process may be repeated by forcing back the tube, as directed, the first
time, and leaving it drawn out the second. The elongated pen will then be filled from
end to end.

page_text: Both ends of the pen being alike, it can be filled through either.
On an emergency, some ink may be drawn in by aspiration, on putting one end of
the pen between the lips.
When preparing to write slightly unscrew both nibs, one as the outlet for the ink
and the other for the admission of air.
To meet special requirements one nib can be made to write finer than the other.
Should the pen remain for some time without being used, shake it a little before
the protecting caps are removed, so as to disturb any sediment that may have accumu
lated in the nibs.
Here follow the indications to the accompanying drawings.

B Section of pen drawing up the ink.

E Section of pen nib.

G Section of cap with india rubber pad.
H The Pen ready for writing.
Having now particularly described and ascertained the nature of my invention, and
in what manner the same is to be performed, I declare that what I claim is the
invention
1stly of the Reservoir pen described in this specification.
2ndly of its having writing nibs at both ends, either of which nibs is used for the
admission of air, whilst the other is being written with.
3rdly of the pen having, when required, both a fine and a course nib ready for use
at the same time.
4thly of two packing boxes divided by an air chamber, to render the connecting
joint between the tubes extra secure.
5thly of a needle, with a spring, adapted to the inside of each nib, so as to close and
open the apertures therein, as more fully described in this specification.
6thly of the filling of the pen by the suction of two tubes, working one inside of the
other, and connected by means of an air-tight joint.
7thly of the introduction of hollow india-rubber pads into the protecting caps to
keep the points of the nibs in good working condition.
8thly of the open ends of the protecting caps being made slightly oval so that by
compressing their longest diameter between finger and thumb, they may be placed
firmly into position.
