IMPROVEMENT IN FOUNTAIN-PENHOLDERS
Year: 1884

page_text: I, HERBERT JOHN HADDAN, of 67, Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said Invention for IMPROVEMENT IN
FOUNTAIN-PENHOLDERS, a communication to me from abroad by Bernhard Köllisch,
Manufacturer, of Nürnberg, in the German Empire, to be as follows: :-
This invention relates to reservoir or fountain penholders and more particularly
to the means of supplying ink to the pen.
The ink is held by an indiarubber tube placed in the axis of the holder, and is
gradually pressed out of the tube at its lower end by twisting.
The upper or rear end of the rubber tube is hermetically attached to a specially
shaped core of metal or other hard material.
The body of this core forms a short cylinder the base of which is toothed at the
circumference and connected in the centre with the rubber tube by a short cone
entering with its lower and thinner end into the cylindrical casing which forms the
main part of the holder and has in its centre the said rubber tube.
The upper edge of this casing is also toothed to fit between the teeth of the core.
The cylindrical body of the core is surmounted by a short toothed cone fitting
with its teeth between the teeth at the inside of a cap which encloses the core
and the upper part of the casing. The lower edge of this cap has a narrow inside
flange adapted to slide along the casing and to support the lower end of a helical
spring abutting with its upper end against an outside rim of the casing. The
spring thus tends to press the cap downward and bring its toothed conical part
into gear with the toothed conical part of the core, in which position the core may
be turned by turning the cap.
The toothed or serrated conical part of the core, as well as that of the cap, is
surmounted by a short cylinder of smaller diameter than the lower cylindrical parts
of.the core or cap.
The core projects through a central opening in the top of the cap and carries
outside a button.

page_text: For filling the holder, the cap (and thereby the core) is turned so that the
ratchet teeth at the lower end of the cylindrical body of the core slide over the
ratchet teeth of the casing and the rubber tube is twisted so as to press out
the air from the same. The mouth piece connected with the lower end of the
rubber tube is now dipped into an ink receptacle, the cap is pressed upward so as
to disconnect its toothed cone from that of the core, and subsequently to lift the
core out of gear with the ratchet teeth of the casing, whereupon the rubber tube
will untwist itself so as to assume its natural shape and suck ink into its interior.
Finally the cap with the core is pushed down into its original position, where
the ratchet teeth are in contact with each other. To supply the pen with ink, it
is only necessary to give a slight turn to the cap, and consequently a slight twist
to the rubber tube by means of the ratchet teeth.

page_text: I, HERBERT JOHN HADDAN, of 67 Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of, this invention, a communication to me
from abroad by Bernhard Köllisch, Manufacturer, of Nürnberg, in the German
Empire, 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 reservoir or fountain pen-holders and more particularly
to the means of supplying ink to the pen.
The ink is held by an india rubber tube placed in the axis of the holder, and is
gradually pressed out of the tube at its lower end by twisting.
The upper or rear end of the rubber tube is hermetically attached to a specially
shaped core of metal or other hard material.
The body of this core forms a short cylinder the base of which is toothed at the
circumference and connected in the centre with the rubber tube by a short cone
entering with its lower and thinner end into the cylindrical casing which forms the
main part of the holder and has in its centre the said rubber tube.
The upper edge of this casing is also toothed to fit between the teeth of the core.
The cylindrical body of the core is surmounted by a short toothed conc fitting
with its teeth between the teeth at the inside of a cap which encloses the core and
the upper part of the casing. The lower edge of this cap has a narrow inside
flange adapted to slide along the casing and to support the lower end of a helical
spring abutting with its upper end against an outside rim of the casing. The
spring thus tends to press the cap downward and bring its toothed conical part
into gear with the toothed conical part of the core, in which position the core may
be turned by turning the cap.
The toothed or serrated conical part of the core, as well as that of the cap is
surmounted by a short cylinder of smaller diameter than the lower cylindrical part
of the core or cap. The core projects through a central opening in the top of the
cap and carries outside a button.
Referring to the drawings: The improved penholder (Fig. 1) is constructed as
follows:
The part c bearing a toothed ring d, is introduced into the the tube a, that is
provided at its upper extremity with a toothed rim b, so that the toothing d gears
into the toothing b. In the part c an india-rubber tube e is hermetically fastened,
the lower extremity is connected with the outlet tube f, which is soldered on to the
tube a, while the part c is revolvable.
The part c is furnished above the toothed ring d with a ribbed cone g and is
situated with its collar shaped projection c¹ in an opening of the case h, which is
also provided with a ribbed cone i. The case or capsule h is pulled down by the
spiral spring k, situated between the tube collar a¹ and the part of the capsule,
and thereby the cone i is pressed upon the cone g.
For filling the holder, the case h is turned. Thereby the case h, by the ribbed
cone i gearing into the ribbed cone g and the toothing b allowing the toothing d
to turn in the same sense, catches the part c. In consequence of this turning of
the part c the india-rubber tube e is rolled up and the air expelled from the same.

Subsequently the tube f is put into a receptacle, filled with ink, then the cone i
is taken off the cone g, by shifting the case h upward, and at last, the toothing & is
lifted out of the toothing b, by shifting the case h farther upward and thereby
lifting the part c of the projection c¹. As the part c with its projection c¹ turns
easily in the opening of the case h, now the india-rubber tube è rolls off again to
its natural position and sucks the ink up. Subsequently the case h and the part o
are again brought into, the position indicated by Fig. 1 and now the holder can be
employed by rolling up again the india-rubber tube e by turning the case h, but
only so far, until sufficient ink is introduced from the tube f into the pen 1, put
into the holder at its lower extremity, from the tube. f. The teeth d having only
a forward motion, the india-rubber tube e remains in its rolled position and sub-
sequently for fresh use of the holder only a turning from one tooth to the next one
is required, for delivering fresh ink to the pen..
Fig. 1 is a sectional elevation, Fig. 2 the same with tube e straight.
Fig. 3 is a separate view of the part c.
Figs. 4 & 5. are modifications being respectively elevation & section of a spring
receiver or guard for protecting the pen which is placed in the cup which is
pressed home & given ȧ part turn to secure the spring in closed position.
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
The contrivance for rolling up and setting fast the rubber tube e consisting of
the casingh with the ribbed cone i in connection with the ratchet teeth b, d.
