Definitions

  • a feed bar in the front compartment abuts agains the raised rim of the aperture orifice, and its rotation is prevented by a rib on the point holder projecting into a notch in the rear end of the feed bar.
  • Ink from a cartridge is supplied from the aperture to a writing point at the front end of the point holder through a capillary slot whose radial depth increases from the point to the aperture orifice and which intersects annular grooves in an intermediate portion of the feed bar.
  • Air is supplied to the grooves through an axial duct in the feed bar surface extending inward from the front end.
  • fountain pens of the type referred to with front end assemblies which can be separated from the barrel of the pen and include a point holder bounding a receptacle for a writing point which partly projects from the point holder in an axially forword direction.
  • Ink supply to the point and the admission of air to the ink reservoir of the pen are controlled by a feed bar received in the tubular point holder.
  • the invention resides in a front end assembly in which an axial passage through the point holder is divided by a fixed, radial partition into a major front compartment and a minor rear compartment connected by an aperture in the partition.
  • a raised rim projects from the partition about the orifice of the aperture in the front compartment.
  • the aforementioned groove 5 is the rearmost member of a group of substantially identical grooves 11 in the intermediate axial portion of the feed bar 31 in which the slot 7, which intersects the grooves 5, 11, is of uniform intermediate depth greater than the depth of the grooves, which are also connected by the rear portion 4 of the air duct.
  • a rib 12 on the inner surface of the point holder 30 engages the notch 6 of the feed bar 31, and thereby secures the bar against rotation in the point holder.
  • the feed bar 31 axially abuts against an integral radial partition 13 of the point holder which divides the passage of the latter into a front compartment and a rear compartment radially bounded by the externally threaded, terminal rear portion 21 of the point holder 30.
  • the ink discharged from the cartridge 25 is replaced by air which enters the cartridge through the ducts 2, 3, 4, the groove 5, the notch 6, the recess 14, the depression 16, and the aperture 18.
  • the front en-d assembly of the invention operates in substantially the same manner when supplied with ink from a collapsible rubber chamber in a conventional manner, as partly illustrated in FIG. 2.
  • a front-end assembly for a fountain pen comprising, in combination:
  • said feed bar being formed with an axially and radially open notch (6) in said rear end portion thereof;
