page_text: I, MARTIN WETTICH, of Wilhelmshöher Attée N° 31, Cassel in the German
Empire, Secretary of The Royal Provincial College, 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 :-
My invention relates to the construction of a fountain or reservoir pen with
holder, that may be used with an ordinary writing pen or with a drawing pen, as
I will describe referring to the accompanying drawings.. Figs. 1, 2 and 3 are
longitudinal sections shewing modified arrangements of the holder, Fig. 4 is a side
view, and Figs. 5 and 6 shew details. Referring first to Fig. 2 as shewing more
complete construction, the holder consists of two principal parts, a fluid reservoir A
and a sleeve B. Within A is a suction tube a b which extends through the one
end of A and reaches nearly to the other end. Through this end pass two
tubes e f and c the latter of which is connected to a caoutchouc bag g. The end e
of the tube e f, through which the ink flows, is enclosed in a short sliding tube r
having a closed end and a slit aperture o through its side. This short tuber can
be shifted along ef by a stud projecting from its side so as to lengthen or shorten
the outflow passage. h and h' are sleeves that can be put on the two ends of the
holder for the pocket; k is a cap closing the end b of the tube a b. For charging
the reservoir, the sleeves h h¹ and cap k are taken off and the tube c is closed by
the tuber and b is immersed in ink; the bag g is then repeatedly compressed and
allowed to dilate, and thus ink is drawn by the tube a b into the reservoir. When
it is sufficiently charged, the cap k is replaced, and the mouth of e is opened, the
pen being then ready for use. If the flow of ink should stop, it can be started by
compressing g. The cap k may however be made with a small side slit admitting
air to maintain the flow, which may be regulated by altering the position of k on b.
Fig. 1 shews a slightly modified construction, the two tubes a band ef of Fig. 2
being made in one piece a b with a side opening d, and the mouth of 6 being closed
by a caoutchouc pad S¹ in the sleeve h'. In the modified construction shewn in
Fig. 3, instead of the caoutchouc bag g shewn in Figs. 1 and 2 there is a caoutchouc
tube R which forms the reservoir. The case A has a side opening E admitting the
finger to compress the tube R. It is of advantage to fix in the covering sleeve h
a piece of sponge, which moistens the pen so that it more readily receives ink, and
clears it of superfluous ink. In order to hold the tuber in position, there are rack

page_text: notches in the edges of B into one or other of which can be engaged the stud pro-
jecting from r, the end of which may be filled with a caoutchouc plug Sm as
indicated in Fig. 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. In a reservoir pen, the combination of the reservoir A, sleeve B, the caoutchouc
bag g, the tubes a b c and e f and means of closing them, substantially as described
with reference to Fig. 2.
2. The modified construction wherein the tubes ab and ef are made in one piece
with side aperture d, substantially as described.
3. The modified construction wherein the reservoir is made as a caoutchouc
tube R within a case A having a side opening E, substantially as described with
reference to Fig. 3.
4. For regulating the flow of ink and closing the tube e, the sliding tube r with
the projecting stud for shifting it in combination with the rack notches of the
holder B substantially as described.
5. For closing the suction tube at b, the cap k with or without a side slit,
substantially as described.
