Fountain pen with ink cartridge. Patented in the German Empire on June 30, 1909.

Fountain pens have become known in which the ink is in a special cartridge is included, which when screwing the closure piece by one on the same located pen is opened. However, this pin does not close the resulting opening, so that the ink from the cartridge itself enter the entire cavity of the pen holder can, causing the ink to come into contact

ίο comes with the screw thread, by means of whose closure piece carrying the spring is screwed onto the sleeve. Smears of the thread are the result, so that the same jams and an opening of the Penholder is then only possible with great force, especially when the penholder not much is needed.

Furthermore, there is the disadvantage that only one and the same ink is used in one holder can use, as a complete cleaning of the sleeve and washing out every trace of the Once ink has been in it is impossible.

The present fountain pen eliminates this

Disadvantages in that with it a smearing of the thread of the closure piece is excluded is, as well as the use of different colored inks with one and the same pen directly after each other is possible.

The drawing shows the fountain pen in section. In a known manner, a sleeve m with a head piece a, e_ is closed by means of a thread, the capsule 0 being pushed over the spring f when not in use. The inner walls of the sleeve are expediently lined with fabric. At the end of the sleeve there is a spring n . A cartridge h consisting of metal, glass, celluloid or the like rests on this. The closure piece a, e carries the ink channel c inside, into which a wick can be inserted, as is known. A slot d is made at a suitable point, which allows the insertion of a pen f of any kind.

The inner end of the closure piece a, e is shaped to match the neck of the cartridge h so that it fits exactly into the same, and is expediently covered with a rubber tube b .

The holder is filled in the following way:

The locking piece a, e is unscrewed by holding the spring holder vertically with the spring pointing upwards. The cartridge h is pushed upwards by the spring η and can easily be removed from the sleeve m. A new cartridge is allowed to slide into the case, it is pushed in with the end i of the closure piece α, β and it is screwed on. As a result, the plug k sealing the cartridge is pushed into the interior thereof and floats in the ink, while the end i tightly closes the neck of the cartridge. The ink now has access to the ink channel c, through which it is guided to the spring f.

From this it follows that it is always easy it is possible to refill the fountain pen without dirtying the fingers etc. Even it is easily possible to use a different colored ink

is, from-

of the previous type, of course, also possible

to use, taking it
the ink channel and the
to wash.

Refilling after
is by means of a syringe
borrowed, but the fact that the cartridge can be removed makes it much more convenient and cleaner. The rubber hose δ located on the end i of the closure piece creates a perfect, liquid-impermeable seal between the end i and the cartridge h , since this, pushed up by the spring η, is pressed onto the rubber b located at the end i .
