Definitions

  • This invention relates to ink reservoir pens of the kind in which the writing point is hollow or tubular as distinct from a pennib to which point the ink is fed from the reservoir during writing.
  • an ink reservoir pen has a hollow point section with a, narrow slot or slots extending lengthwise in its wall and an ink regulator member mounted within and close to the wall of the point section and extending to the forward end of the ink reservoir.
  • the end of the point section has a continuous surface, the slot or slots through its wall not extending to the tip.
  • the point section is of a non-corrodble metal, such for example as gold. Gold, however, is unsatisfactory for the actual writing point by reason of its softness.
  • a feature of the present invention therefore consists of a point section having a tip of a hard wearing non-corrodible material such as iridium, or possibly a stainless steel.
  • Fig. 2 is a section on the line 2--2 of Fig. 1,
  • Fig. 3 is an external view of the point section
  • Fig. 4 shows, also in section, ythe writing end of a, modified form of pen
  • Fig. 5 shows a modified ,form of point section
  • the barrel I is of vulcanite or other material employed for such purpose and of usual form.
  • the ink containing sac Z' together with the usual apparatus for collapsing the sac in order to ll it.
  • a front section 3 which may be V0f the same material as the barrel and it is secured thereto by co-operating threads 4 in the usual way.
  • the inner end of the front section 3 comprises ashort spigot 5 to which the front end of the sac 2 is cemented.
  • the front section 3 is bored from its inner end for a certain distance and this bore 6 connects with a short bore 'l of smallerdiameter which in turn connects with a bore 8 of slightly larger diameter extending to the front end of the section.
  • the bore 8 vis threaded.
  • the point section -9 is hollow with its front end of conical shape and its rear end Ill tubular and threaded to screw into the bore 8 at the iront end of the front section 3. It is of gold or other non-corrodible metal with a tip II of iridium or other hard non-corrodible material. Slots l2 for example four and equally spaced extend longitudinallyA of the point section 9 towards this tip and Preferably partly into the iridium point I I.
  • An ink regulator member I3 comprises a rod conveniently of vulcanite which may fit freely within the reduced bore 'l of the front section 5 or may be a friction fit therein. It hasa conical forwardend I4 to conform to and is mounted close to the inner surface of the wall of the point section 9 and when it ts freely in the reduced bore 1 it is held in place by a 1ongitudinal depression I5 in the wall of the rear part IIJ of the point section. This depression I5 forces the ink regulator member I3 against one side of the inner wallof the point section.
  • This ink regulator member has a series of parallel transverse grooves I6 around its front end. These grooves are in two batches I5' and
  • the rear end of the point section 9 is of the same diameter as the front end of the front sece tion ⁇ 3 so thatthere is no shoulder at the junction of the two and its outer surface forms a continuation of the front section of the pen.
  • the wide groove I8 in the ink regulator member constitutes a passage to supply air to the interior of the sac when ink is fed from it through the narrower groove Il. Air is supplied to the groove I8 from the space 20 at the rear end of the point section. 2I are small holes through the wall of the point section to admit air to the space 20.
  • air is supplied through the holes 2
  • the point section may be made in two parts 9a, 9b as illustrated in Fig. 5, the two parts being secured together by welding.
  • the threading on the point section, when used may be in a series of separate raised parts as shown at 24 in Fig, 6.
  • the depression I5 then also constitutes an air vent.
  • An ink reservoir pen comprising a hollow pen barrel, a hollow writing point section extending therefrom and having a narrow slot extending lengthwise in its wall and a rigid ink regulator member mounted within the point section to extend to the forward end of the ink reservoir ⁇ for regulating the flow of ink into said point section and through said slot.
  • An ink reservoir pen comprising a hollow pen barrel, a hollow writing point section extending therefrom and having a plurality of narrow slots extending lengthwise in its wall and a rigid ink regulator member mounted within the point section to extend to the forward end of the ink reservoir for regulating the ow of ink into said point section and through said slots.
  • An ink reservoir pen comprising a hollow pen barrel providing an ink reservoir, a hollow writing point section extending therefrom and having a rounded writing tip with a continuous surface and a plurality of slots extending lengthwise in its wall to a point short of the tip, and a rigid ink regulator member mounted within the point section to extend to the forward end of the ink reservoir for regulating the flow of ink from the barrel into the point section and through said slots to the tip.
  • An ink reservoir pen comprising a hollow pen barrel providing an ink reservoir, a hollow writing point section extending therefrom and having a rounded writing tip with a continuous surface and a plurality of slots extending lengthwise in its wall to a point short of the tip and a rigid ink regulator member having a series of parallel transverse grooves around its front end mounted within the point section to extend to the forward end of the ink reservoir for regulating the iiow of ink from the barrel into the point section and through said slots to lthe tip.
