Title: Improvements in ball pointed fountain pens
IPC: B43K1/08
Filed: 1950-12-05
Abstract: 719,132. Reservoir pens. MABIE, TODD & CO., Ltd., and SEARS, E. S. Nov. 23, 1951 [Dec. 5, 1950], No. 29759/50. Addition to 692,212. Class 146 (3) The ball-point pen claimed in the parent Specification is modified in that the means for adjusting the rod 19 which forms the base seat for the ball, is associated directly with the point section 10 at the rear end thereof. The body section 5, to which the ink sac 9 is attached, has mounted therein, by screwthread means 14, the point section 10 fitted with a housing 11 for a writing ball 12. The rear end 15 of the point section 10 is provided with a. fine screw-thread to receive an adjusting nut 16 of cap form which is recessed to receive the rear end of the rod 19. The upper end of the rod 19 abuts the ball 12. The nut 16 is cut away at two opposite sides to provide apertures 21 for the passage of ink from the reservoir sac to the point section. A metal, plastic, or other non-corrosive partition 22, formed with a longitudinal channel to provide a seating for the rod 19, is forced into the feed duct in the point section 10; this partition divides the duct to form two channels E, one for air and the other for ink. Ink is retained in the bore 24 of the point section, when the pen is held point up, by the meniscus formed at the point where the nut 16 joins the rear end of the point section. During refilling, ink enters the reservoir through a chamber A, aperture C, chamber B, aperture D, channels E and apertures 21. When the pen is point upwards, ink will not flow back into the reservoir due to the forming of the meniscus near the nut 16, as described above, but will flow into the chamber B, and this overflow will be used first before ink is supplied from the reservoir.
