Improvements in Fountain Pens.
We ADOLPH KRULIS, GABRIEL HAIM ADUTT & VICTOR HAIM ADUTT of
Vienna in the Empire of Austria, the first residing at VII., 46, Kirchengasse,
Imperial & Royal First Lieutenant, the second & third at I, 1, Predigergasse,
Turkey Merchants 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 present invention relates to fountain pens and consists principally of a tubular
holder for the reception of the ink, having an outlet tube bat its lower end
preferably inclined towards the nib and of sufficient diameter to allow the ink to
flow freely.
In order to make our invention more clear we refer to the accompanying drawings
in which similar letters denote similar parts throughout the several views.
Fig. 1 is a sectional elevation
Fig. 2 a modified form and
Fig. 3 an elevation of our improved fountain pen.
C
In the upper part of the tubular holder a a peculiarly formed piece of india
rubber c is arranged, which is adapted to close the tubular holder a at both ends, at
the top by being fixed in the same and at the lower end by means of the valve
hereinafter described.
A cap d closes the open end of the tube a above the plug e said cap being
connected to a thin rod e descending through tubes a and b and having a valve fat
its lower end, by means of which the lower end of the tube is closed.
The valve f is kept down on its seat fi by means of the rubber plug or buffer c.
According to the manner in which the plug is arranged in the tube a the valve is
either pressed upward against its seat by the plug e exercising a pressure under the
d Fig. 1, or as in Fig. 2 it is pressed downward on its seat by the rubber plug
cap
being attached to the rod e. In both cases the plug c which is immoveably fixed
in the tube, is continually exerting pressure either upward or downward. In Fig. 1
the valve seat ft is arranged above the valve f and in Fig. 2 below the same.
C
We preferably construct the tubes a and b of such diameter that the ink could
flow out freely were the valve not present, although the tube a is hermetically
closed at its upper end, so that the quantity of ink allowed to flow out depends upon
the distance which the valve is opened.
The valve is opened by depressing the cap d (Fig. 1) or raising the same
(Fig. 2).
In order to conveniently fill the holder with ink we preferably arrange a revoluble
sleeve 9 in a suitable position on the holder, said sleeve covering a hole o in the
tube a, and having a hole corresponding to o, so that on turning it round, the two
holes correspond or the sleeve may be full and the opening o in the tube exposed
by sliding the said sleeve up or down the holder. The tube a may then be filled by
means of a drop counter of the well known construction, or any other suitable
means. The lower end of tube a may be adapted to receive the pen i (either an
ordinary writing pen or a drawing pen) or as shown in the drawing an ordinary
pen holder sleeve à may be arranged on the same.
It is advisable to wet the pen previous to using the same, in order that the ink
may more readily flow on to the same.
Having now particularly described and ascertained the nature of our said inven-
tion and the manner in which the same is to be performed, we declare that what we
claim and desire to secure by Letters Patent is :
1. Fountain pens having a holder a adapted to serve as ink reservoir, with an

page_text: outlet tube of suitably large diameter, attached thereto and having at its lower
end the valve and seat which former is closed when in a state of rest and
provided with a rod e having a cap d, in combination with an india rubber plug or
buffer e fixed in the tube a and adapted to press the valve fupwards or downwards
on to its seat, substantially as described.
2. In combination with the fountain pen covered by Claim 1 an orifice o in the
tube a which may be covered or exposed by means of a revoluble or sliding sleeve g
substantially as described.
