COMPLETE SPECIFICATION.
Improvements in Fountain Penholders.
We, JOHANNES PAUL STEINBACH and KARL HERMANN STRACHE, both of Holbein-
strasse, Dresden, Saxony, Lithographers, 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.
This invention relates to a fountain penholder having a wholly or partly
elastic ink chamber which is acted upon by automatically occurring pressure or
vibration of the pen and in which penholder any ordinary kind of pen may be
used.
In the accompanying drawing Figs. 1, 2, 3, are longitudinal sections of the
fountain penholder with parts of the same in different positions of use and
Fig. 4 is a cross section taken through the front end and Fig. 5 an end view
of the same.
a, b, are two sleeve or hollow cylinder parts internally screw threaded at their
meeting ends and there held together by an externally screw threaded plug e
which is provided excentrically with an orifice d and carries by means of a
small busli e fixed therein a suitably shaped elastic india rubber ink chamber f
which completely fills the encasing part and extends outwardly in the form of
an apertured beak g.
Above the ink chamber f and beak is slid the pen which is either carried
and held fast by the ink chamber itself, as shewn, or for this purpose a spring
ring or the like may be slid into the front end of the sleeve part a so as to leave
the rear portion of the pen free to bear upon the ink chamber.
The sleeve part or haft serves as an ink reservoir which feeds, through orifice d,"
the chamber with ink and is closed at the back end by a screw cap k.
In writing, the penholder is handled like any ordinary penholder. The feeding
of the pen takes place automatically from the elastic ink chamber f owing to
the back part of the pen (Fig. 3) being somewhat tilted upon the back part
of the ink chamber when the ordinary pressure of writing on paper is exercised,
the front edge of the sleeve part a then serving as the point of oscillation. In this
way the air or ink is somewhat compressed whereby a corresponding outflow of
the ink through the beak g takes place.
The charging of the ink inte the chamber f also occurs automatically as each
time the penholder is released or laid on one side the pressure is removed and the
previously pressed ink chamber becomes again inflated or bulged out and
thereby draws ink from the reservoir b. In this latter part there is fixed close
to the plug e another plug of india rubber or the like, similarly provided with
an excentric orifice m which by giving a slight turn to the sleeve may be
brought to register with the orifice d or inversely to shut off this orifice (Fig. 1).
This latter is done, when the reservoir sleeve is to be charged with ink, so as
to prevent the flow of the same from b into f.
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: —
Fountain
nen
holder in which an alastic o chintessible ink chamber f

page_text: inserted in the front end a of a hollow penholder haft serving as ink holder
feeds the pen inserted between the ink chamber f and the part a by means of the
slight compressions continually exercised on said ink chamber when writing
is being done, substantially as described and shewn.
