Front part for cartridge fountain pen

The object of the innovation is a front part for cartridge fountain pens, which is characterized by the fact that it has a mouthpiece with a hole for receiving an internal feeder and a recess "for receiving the writing pen, the mouthpiece at its rear end always with a flange with a shoulder as an abutment is equipped for the internal feeder and contains a cleat for engaging the air groove to prevent the internal feeder from twisting.

lie drawing represents an embodiment of the inflation represent. "

The gate part "consists of the mouthpiece. (II) on the front side of which you can see a hole (2 ©) for receiving a linens feeder (III) that is ready- to-use without any work and a recess (22) for the installation of the pen '(I) is located . at the mouthpiece back is ι (21) provided on the Imfang a © evsindestüek to Einsehrauben in the Mllhalter container in 'its center, the mouthpiece is provided with one of a MFT (18) and three capillary Iuten (19) A perforated socket (1?) for the fintenpatroiien, which is firmly connected to the mouthpiece (II) via the socket (15). In addition, there is an internal thread (23) on the inside of the threaded piece (21) for attaching a filling mechanism " , which is used when there are no ink cartridges available.

So the front part consists of only two pre-molded Plastic parts, namely the mouthpiece (II), the fine feeder (III) and the pen (I). '' ·

With an appropriate design of the capillary seat (7) of the annular compensating chambers (11 ") and corresponding 3) dimensions of the ventilation grooves (2), (3), (4), C5)> (6) »(16) and (18) the ink supply fulfills its regulation-" function in an excellent way

In detail, the figures show the followingί

Fig. 5 shows the side of the flange (13) of the mouthpiece (II) firmly resting on the sinter feeder (III) » On the flange (13) of the mouthpiece (II) is the Approach (15), in which you can see the three "capillary ankle braids (19-) and the air groove (18) are located ". About approach (15) ■ is penetrated through the cover "(16); this opens into the air groove (14).

Fig. Β is a section through the mouthpiece (II), the spring (If and the! Eintenzuführer (III). You can also see the hole (1) on the ink feeder provided for dismantling the spring and the ink feeder, the air ducts ( 2) and (3), the two ventilation ducts (9) and the side teeth (8) with the side walls (W). '

Fig. 7 shows the spring seat (.21).

8 is a section through the sewing neck. (2.1) on Mouthpiece (II) and through the attachment nozzle (17) for the cartridge, seen in sighting the pen. "".

Puncture

When screwing together the cartridge fountain pen Yord part " with the container of the fountain pen butting the recording?) the ball of the ink cartridge into the same, this creates a slight overpressure, which unites in the three capillary seat braid (19) and the air groove (18) drives.

1er on the approach (15) of the ^ lansehes (13) tightly fitting, durch'den in * the air groove (6) engaging lug (12) against Twisting sieved and fastened together with the spring (1) by a press fit (Eintenzuführer (III) takes over with his deeply incised at this point Ϊinte for "further! Transport forward to the spring;

Are the capillary channels (19) and (7) once with 2inte wetted, so is a sand-free with this construction ! Single supply to the spring guaranteed. Bas while writing used ink volume must of course in the cartridge air flowing in must be replaced. This comes through the Air ducts (2), (3) and (4) on the underside of the fin feeder (III) 'to the air ring groove (5) and: .of; this in the above the air groove (6) on the lintenzipper (III).

The air groove (6) of the fin feeder (III) is in connection with the air groove (-14) on the Flahseh (13) of the lundstüGks '(H), this in turn ends in'c | ie ^ loin (16) of the' approach ( 15) on the flange. (13) of the lundstüeks (II>. ^R air groove (18) in the receiving socket (-t-7) opens at its end facing the "iintenzuführer (-IiI)" in the "aperture (16), so that the air supply is ensured. *

Regular activity

lei overpressure caused in the parent cartridge of the lüllhalterj due to sudden warming of the air pressure visual fluctuations, The cover (16) is first closed with the Ϊinte, so that none more air can get into the linten storage room. With further expansion: fill the air in the ink supply room * see / Then the air channels (H) and '(6), then the ring groove (5) follows. It is important that the air groove (4) on the underside of the line feeder (III) is deep and "board, and inside, rounded is designed so that a further flow of the fuse in the air duct (4) is prevented, so you can see the inside slightly "conical, ring-shaped compensation chambers Fill (Ti) with the excess! Compensation chambers dl) can be improved by the channel (7) under the pen (I) as flat as holds possible so that a stumbling block takes place as it is A ¥ b. 1 shows. '

If the line should come forward and the spring should flow off to the side, then it is of the utmost importance that the air duct (2) is not flooded by the ink, otherwise the ventilation of the compensating chambers ... (11) is not guaranteed, and They cannot fulfill their function of absorbing excess fines, which is why the air duct (2) is tightly sealed off against penetrating fines by the side walls (1Θ). Rather, it is taken up in the side toothing (8), which in turn are connected to one another by the ventilation grooves (9) and thereby "make it possible to fill the side toothing with ink If you have filled the ink, the.! Cinte. Is first sucked out of the lending chambers (11) when you are writing If unct ion secured. - ". ■ '. . '".""■.-"; ., "-. ■ .. ■.;.: ■■""■■; ■ ■ '■■■ -.-
