Improvements in Reservoir Pens.
We, JEAN FALCONNET, of Magland, Priest, JULES MICHEL RUBIN, of Araches,
Watch Maker, JEAN EMILE RUBIN of Araches, Watch Maker, and JOSEPH SAUTIER,
of Magland, Propietor, in the Department of Haute-Savoie, in France, do hereby
declare the nature of this invention to be as follows:-
The invention consists of a pen-holder which is adapted to contain a supply of ink
which is fed to the pen by means of a piston acted upon by a screwed rod.
The said invention comprises a tube which serves as a pen-holder as well as an ink
reservoir. In the axis of and concentric with the said tube is placed a rod provided
with a male screw-thread and passing through a piston having a corresponding
female screw-thread. The one end of the screwed rod is fixed to a cap which covers
one end of the tube, and a ring, fixed to the tube by means of screws, prevents the
withdrawing of the said cap and rod by means of a pin passing through the rod and
bearing upon the said ring. From this it follows that if the cap is turned, the rod
will also be turned and the piston thereby caused to advance toward the end of the
tube which bears the pen or toward the said cap.
The front end of the tube is provided with a conical tube having near its top a
slot or hole the said conical tube being fixed to a ring screwed into the main tube by
means of a threaded portion. The pen is fastened between two tongues. A pro-
tecting tube is provided which has formed therein a female screw-thread corre-
sponding to a male screw-thread on the holder, the said tube being placed over the
pen when not in use.
The ink being introduced into the main tube between the piston and the ring or
conical tube, the pen may be supplied therewith by turning the cap so as to cause the
piston to press the ink through the slot or hole.

COMPLETE SPECIFICATION.
Improvements in Reservoir Pens.
We, JEAN FALCONNET of Magland, Priest, JULES MICHEL RUBIN of Arâches,
Watch maker, JEAN EMILE RUBIN of Arâches, Watch Maker and JOSEPH SAUTIER,
of Magland, Proprietor, all in the Department of Haute-Savoie in France, 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:-
The invention consists of a pen holder which is adapted to contain a supply of ink
which is fed to the pen by means of a piston acted upon by a screwed rod.
In the accompanying drawing
Figure 1 is a longitudinal section through the penholder drawn to about full size.
Figure 2 shows the corresponding protecting tube and
Figure 3 is a section of the front part of the pen holder drawn to an enlarged scale.
Similar letters of reference refer to similar parts in all the Figures.
A is a tube which serves as a pen holder as well as an ink reservoir.
In the axis of and concentric with the said tube A is placed a rod B provided with an
external screw thread and passing through a piston E having a corresponding internal
screw thread. The one end of the screwed rod B is fixed to a cap C which covers
Price 6d1

page_text: one end of the tube A and a ring D fixed to the tube A by means of screws d
prevents the withdrawing of the said cap Cand rod B by means of a pin b¹ passing
through the rod B and bearing upon the said ring D. It follows from this that if
the cap is turned the rod B will also be turned and the piston E thereby caused to
advance toward the end of the tube A which bears the pen or toward the said
cap C.
The front end of the tube A is provided with a conical tube G having near its lop
a slot or hole o the said conical tube being fixed to a ring F screwed into the main
tube A by means of a threaded portion b. The pen K is fastened between two
tongues and H. M is a protecting tube which has formed therein an internal
screw-thread corresponding to an external screw-thread on the holder, the said tube
being placed over the pen when not in use.
The ink being introduced into the main tube A between the piston E and the
ring For conical tube G the pen may be supplied therewith by turning the cap C
and rod B so as to cause the piston to press the ink through the slot or hole g.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The combination of tube A, rods B provided with external screw-threads and
piston E having corresponding internal screw-threads and of the conical tube G
provided with hole g substantially as shown and described and for the purpose
specified.
