page_text: I, HANS SIENEL, of Mähr. Neustadt, in the Empire of Austria, Post and
Telegraph Operator, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a reservoir pen in which the actual pen or nib is
formed of a cone, the surface of which is divided by longitudinal grooves.
The point of this cone is of some hard material, such as iridium. This cone is
enclosed within another cone, the interior surface of which is smooth, and
which near its point has a small enlarged chamber, through which the point of
the inner cone projects, this chamber being for the purpose of collecting the
ink which flows to it along the grooves in the inner cone, so that a small supply
of ink may be always present at the point of the pen. The handle of the pen,
which forms the ink reservoir, is screw threaded at one end to receive the screw
threaded cap which carries the nib, and in this cap is an india rubber sleeve
forming the extension of the liolder and carrying the outer cone aforesaid. Within
this sleeve which is somewhat flexible and compressible is an india rubber ball
into which ink may flow from the reservoir through the tube attached to the
ball, and this ball is fastened upon, an inward' extension of the outer cone so that
the ink which enters the ball may pass into the outer cone by the space which
surrounds the stem of the inner cone.
In the use of this reservoir pen it is sufficient to give a small lateral pressure,
as for instance the pressure exercised in writing to the conical end of the pen.
This causes the ink to enter tlie said ball and to pass therefrom along the grooves
of the inner cone to the. writing point.
At the other end is a cap in which holes are made for the admission of air,
and this cap is separated from the interior of the reservoir by the closed end
of the reservoir in which a small admission tube is placed, on the outside vť
which is a valve, over which is a cap having a hole in it and so placed in com-
munication with the outer cap before described.
This small inner cap is surrounded by a ring having a hole in it corresponding
with the hole in the inner cap. By turning this ring the hole in the inner cap
may be more or less closed, or entirely so if desired.

I, HANS SIENEL, of Mähr. Neustadt, in the Empire of Austria, Post and
Telegraph Operator, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a reservoir pen with a conical pen uib or writing
stylus as represented by a longitudinal section in the annexed drawing and
differs from the usual reservoir pens in the following improvements. The ribbed
conical nib is covered by a smooth hollow cone which is connected to the hollow
handle serving as ink chamber by an elastic intermediary body. The point
of the conical pen consists of some material which offers great resistance to
wear. Further, behind the writing nib is arranged a ball for squirting ink
which is compressed by a side pressure on the pen during the act of writing,
to conduct the necessary ink to the point of the pen.
The hollow handle of the reservoir pen is composed of two cylinders a and b
which are inserted one into the other, the cylinder a being perforated for the
purpose of admitting air. At the bottom of the cylinder b which serves as ink
reservoir there is inside a small tube c for admitting air and outside a valve cap d
The opening e of this valve cap can be more or less adjusted, or entirely closed
by turning the movable ring f having a. similar opening. The opening at the
other end of the ink reservoir which serves for the purpose of ink filling is
screw threaded, in order that the part 7 of the pen can be screwed in after filling.
Ing is inserted an inside rubber sleeve in the space within which is an
indiarubber ball i. This latter has at one end a small tube & communicating with
its interior and at the other end it is fixed to a sleeve of strong material rigid
with the cone n Between the flange g and the sleeve is a packing m which
closely surrounds the small tube . Over the sleeve is fitted, a hollow cone
having a smooth surface inside and outside and for the purpose of a better con-
nection provided with a circular groove to receive the thickened edge of the
rubber body. The hollow cone and the sleeve / surround the pointed. cone-o
the face of which is provided with longitudinal grooves up to the point which
is composed of a hard material for instance osmium or iridium. The cone is
provided near its open or truncated apex, with an interior groove forming a
chamber in which the grooves of the cone o end.
Cone o has fixed to its base a rod s terminating in a tubular extension & open
at its end and passing through tube k which it fits and having the small orifice
which affords communication between the interior of the rubber ball and the
reservoir b.
When writing, the ink flows out of the reservoir through the small tube r
into the ball i, from there into the sleeve and into the grooves of the cone o and
to the chamber 7. To cause the ink to flow more readily to the writing point of
tie pen, it is sufficient to give, a sharp lateral pressure on cone by which
sleeve his deflected and a pressure is effected on the rubber ball i, to conduct
the necessary quantity of ink to the writing point. The use of this reservoir
pen offers the following advantages.
People suffering from writers cramp, will not do so when using this pen because
the elastic body 7 yields during the writing. The pen can be employed for a
long time before renewal of the point is required. In using this pen it is
almost impossible to soil the fingers or blot the paper.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
Reservoir pen having a writing stylus of longitudinally grooved conical form
which is surrounded by a smooth hollow truncated cone, and wherein the ink
flowing from the chamber b for example through a small tube with opening t
into a rubber ball and from this through a connecting sleeve to the grooves
of the cone a and to a chamber q is caused to flow more readily by pressure upon
the cone which is connected by the chamber b by means of an elastic connecting
sleeve h.
