Definitions

  • Fig. 7 illustrates in enlarged longitudinal section the forward portion of the embodiment of Fig. 1 with the Writing element partially shifted to the writing position;
  • Fig. 8 illustrates the embodiment of Fig. 1 in enlarged embodiembodilongitudinal section with the writing element in an overextended position
  • Fig. 10 is an enlarged partial longitudinal sectional View of the embodiment of Fig. l illustrating the operating mechanism for extending and retracting the writing tip;
  • the sleeve When it is desired to retract the writing tip to the sealed position, the sleeve is once again manually actuated to produce the overextension of the writing element illustrated in Fig. 8 and the overextension of the latching element 84 illustrated in Fig. l0.
  • a slidable sleeve 92 is disposed within insert 82 mounted on sleeve 26 and movable between predetermined limits. The limits are determined by the rearward iiange 91 of insert 82 and a ring 93 which is forced within the forward end of insert 82.
  • capless concept employing a deformable sealing member may be employed with other fountain pens which may not use an extensible filling tube or a capillary type of reservoir, the advantages of the combination of these elements is believed manifest and clearly set out in the introductory portions of this speciiication.
  • concept of two concentric cylinders, one of which comprises a writing element to provide improved fluid feedings, and the other a filling tube may be employed with other forms of reservoir types and filling mechanisms.
  • a fountain pen comprising a hollow body portion having an open forward end, a exible resilient sealing member closing said open forward end having a slitted central portion deformable to define a central aperture and mounted within said body portion adjacent said open forward end, a writing point mounted in said body portion for movement relative to and through said open forward end and said slitted central portion, said movement being between point exposed and point concealed positions, substantially cylindrical means surrounding said writing point and carried thereby, said cylindrical means being responsive to said movement to the point exposed position to engage and open said slitted central portion whereby said point may freely move to said exposed posil tion, said cylindrical means being axially movable relative to said writing point and resiliently urged to a position forwardly of said writing point, and stop means supported within said body portion to limit forward movement of said cylindrical means to a forward position within said body portion deforming said sealing lmeans when said writing point is moved through said open forward end, whereby said writing point may be moved forwardly of said cylindrical means and said sealing member to said point exposed position.
