Definitions

  • ABSTRACT In a fountain pen, a readily removable probe is located in the feed bar of the pen and includes longitudinally extending air and ink channels therein, the probe supporting the nib of the pen.
  • Fountain pens usually have an ink feed bar which extends from the barrel of the pen and projects therefrom to lie beneath the nib, the feed bar playing an important part in ensuring that the ink is fed by capillary action to the nib tip.
  • some inks such as that commonly known as India ink, quickly dry thereby clogging the pen or at least preventing immediate writing therewith. This is particularly so if the pen nib has been left exposed to the air.
  • a fountain pen according to the invention includes a readily removable probe which enages in a slot in the feeder bar and projects therefrom to form a support beneath the nib and, in fact, takes the place of the end of the conventional feeder bar. The probe can thus be readily removed should the pen be clogged with dried ink thereby allowing the pen to be readily cleaned.
  • a typical probe which has been used successfully in this connection has in its upper surface, i.e. that immediately adjacent the nib, a first inkreceiving capillary channel opening out into an airreceiving channel and a somewhat wider portion or snout adjacent the probe tip replaces the end of the conventional feeder bar. It is believed that the combination of air channel and ink channel is very material in reducing the tendency of the ink to dry.
  • the probe tip preferably extends as near as possible to the writing tip of the pen nib.
  • the probe has an outwardly extending flange or shoulder for facilitating removal of the probe from the feed bar of the pen.
  • the probe has an outwardly extending flange or shoulder for facilitating removal of the probe from the feed bar of the pen.
  • other means can be provided if desired on the probe for facilitating its removal.
  • the underneath of the probe could be provided with a small recess.
  • the probe will have, in plan, the general shape of an arrow.
  • the head of the arrow may, of course, be modified depending upon the type of nib which the probe is to support.
  • the probe may be made of any suitable materials and it will usually be made of a flexible material such as,for example nylon, an acetal resin, polypropylene, polyethylene or other plastic materials.
  • the fountain pen of the invention may be such that the probe extends longitudinally outwardly nearly as far as the end of the nib.
  • the nib may be positioned between a probe and a pen hood, the hood being above the nib andthereby preventing it from flexing too far from the probe during writing and further preventing air getting to the top surface of the nib.
  • the hood need not be used.
  • the probe is so dimensioned with respect to the particular type of fountain pen in which it is to be used, that it can repeatedly be inserted into and removed from the feed bar of the pen.
  • the inner end of the probe will project into an ink reservoir in the fountain pen.
  • suitable conduit means can be employed to connect the probe with the ink reservoir.
  • the ink reservoir can be in any convenient form, but prefilled ink cartridges are generally preferred.
  • a fountain pen constructed in accordance with the invention exhibits a far lesser tenedency for the ink to dry in the area of the nib than many fountain pens hitherto used.
  • FIG. 1 is a plan view of a probe in accordance with the principles of the invention
  • FIG. 2 is a side view of the probe shown in FIG. 1;
  • FIG. 3 is a cross section of the probe as viewed substantially along lines 3-3 of FIG. 1;
  • FIG. 4 is a cross sectioned end perspective view of the probe of FIG. 1 situated in the feed bar of a fountain pen;
  • FIG. 5 is a side elevation view the front portion of the fountain pen including the nib.
  • FIG. 6 is a-plan view of an extractor for removing the probe from the pen.
  • FIGS. 1 to 3 there is shown a fountain pen probe 2 having an elongated body portion 4 and an arrow shaped head 6. Throughout the length of the probe -2 is a first ink-receiving capillary channel 8 which is positioned beneath and opens out into a second wider air-receiving channel 10 (see especially FIG. 3).
  • the probe 2 is so dimensioned and shaped that. it can be repeatedly inserted into and removed from a feed bar 12 of a fountain pen 14.
  • the probe is provided with shoulder 16 (see FIG. 2) against which a force can be exerted by a thumb or finger-nail or by other means such as the extractor tool 28 shown in FIG. 6.
  • the shoulder 16 will be located in a position which is accessable when the probe is in the feed bar of the fountain pen.
  • the nib 18 is inserted through the opening 30 and the probe is extracted by pulling on the tool 26 with the edge 32 in engagement with shoulder
  • the fountain pen shown in FIG. 5 is such that the head 6 of the probe 2 extends nearly to the end of a pen nib 18.
  • Positioned above the pen nib 18 may be a hood (not shown) which prevents the nib 18 from flexing too far away from the probe 2 when the fountain pen is in use. Obviously, if the nib 18 flexes too far away from the probe 2, ink may not reach the nib 18 in satisfactory amounts. 'In this connection it will be seen most clearly from FIG. 2, that both channels 8 and 10 converge toward the front point 22 of the head 6 of the probe 2, thereby ensuring that the ink reaches the nib 18.
  • the nib 18 is preferably a so called music nib, but other types of nibs may obviously be used if desired.
  • the pen of the invention has been found to be extremely useful with so called India ink, but of course is quite suitable with other inks.
  • the sides of the airreceiving channel 10 are straight. If desired, however, the channel 10 may have any other appropriate crosssectional shape, for example V-shape.
  • An ink pen of the type including an ink feed bar and a nib, the improvement in said pen comprising in combination therewith:
