Young, Southbury, Conn., amignor to Waterman Pen Company, Inc., New York, N.Y., a corpora- -tion of New York Filed July 18, 1955, Ser. No. 522,496 7 Claims. (Cl. 120-51) This invention has to do with the mounting of a nib in the forward end portion, or section as it is called, ofv a fountain pen.

,The principal object is to provide a novel form of mounting which not only holds the nib securedly but which also permits much (or, if desired, all) of the nib to be exposed and supported ush with the adjacent outer sur-face of the section so as to present an attractive, stream-lined appearance. The object is achieved without resort to the tubular type of nib with which certain pens have heretofore been equipped.

In general, the above result is achieved by utilizing a nib which, when in position, may have the appearance of a nib of standard design, including the usual U- shaped rear end, but which has depending side ange means which penetrate the section and serve, in part Aat least, to interlock the nib and section.

The invention will -be better understood from the following description of the preferred form illustrated in the accompanying drawings of which:

FIG. 1 is a partially sectioned side view of a `fountain pen incorporating the preferred `form of the invention;

FIG. 2 is an exploded perspective view of the nib, a reinforcing element and the section;

FIG. 3 is an enlarged top plan view (partially sectioned on the line 3 3 of FIG. 5) of the forward end of the section, with the nib removed;

FIGS. 4 and 5 are transverse sections on the lines 4 4 and 5 5, respectively, of FIG. 3;

FIG. 6 is a vertical longitudinal section of the forward end of the pen of FIG. l, the section being taken on the line 6 6 of FIG. 7;

FIGS 7 and 8 are transverse sections on the lines 7 7 and 8 8, respectively, of FIG. 6;

FIG. 9 is an enlarged top plan view of the forward end of the section (with the nib in position) and partially sectioned. as on the line 9 9 of FIG. 8; and

FIG. l-O is an enlarged side view of a portion of the nib.

The particular pen shown in FIG. l for the purposes of' illustration includes a barrel 1, housing an ink cartridge 2 the forward or left-hand end of which is pierced by a tube 3 which, through a feed forming no part of the present invention, serves to conduct the ink from the cartridge to the nib 4. The nib is mounted at the forward end of the so-called section, generally designated 5.

Throughout this specification and the claims, the terms front, forward etc. are used to designate that portion of an element which is nearer to or faces the nib end f the pen and the terms rear, rearward etc. are used to designate the portion of an element which is remote or faces away from the nib end of the pen.

Within the section 5, which is of open-ended tubular form, is an ink storage member 6 the details of which (so far as ink storage and flow are concerned) like-wise form no part of the present invention.

The forward end of the section incorporates a nibreceiving cavity. In this preferred form the cavity, in plan view, is U-shaped, the forward part of the cavity being a slot providing opposed side surfaces 7 (see FIG. 4). The slot is of a width less than the diameter of the section bore so that, at the intersection of the surfaces 7 with the surface of the section bore, under-cut portions or shoulders 8 are formed. The rear end of the nib cavity Assuming the section to be plastic molded, the member` I yoke of the reinforcing member terminates short ofV isbridged by a nib seat 9 (see FIGS. 2 and 5) whichj is depressed to a depth approximately equalling the thickness of the nib 4. Accordingly, when the U-shaped rear end 10 of the nib is engaged with seat 9, the outer surface (FIG. 9) substantially abut these shoulders so that, in' plan view, the projecting front lend of the nib appears` as a stream-lined extension of the section.

As stated above, the nib is provided with depending sidev flange members which penetrate the section and serve to interlock the nib and section. As illustrated, the nib has depending side anges 17 which, in this preferred form, terminate in integrally formed lateral projections 18, the side flanges engaging the section surfaces 7 and the lateral projections engaging beneath the section shoulders 8 (see FIG. 7).

The rear end portions 19 of projections 18 are slit and bent upwardly and outwardly so as to engage behind the rearwardly facing section shoulders 20, thereby locking the nib against withdrawal in a forward direction (see FIGS Sand 9) The forward end of the ink storage member 6 is a snug t in the section bore (see FIG. 6) and its upper wall portions 25 engage the under side of the nib to complete its support and also engage the inner sides of the depending nib flanges, thereby holding the flanges spread and their lateral projections engaged beneath section shoulders 8.

In this preferred embodiment the nib cavity is shown reinforced by a member which serves also to ornament the pen section and without disturbing its overall streamlined appearance. This member, generally designated 26 in FIGS 1 and 2, may be a metal piece embedded in the section so that its surface is dlush with that of the section,

26 can be inserted in the mold and the section molded to it. At its forward end member 26l includes a yoke 27 and extending rearwardly are wings 28 united at their ends -by a band 29. As appears in FIGS. 2 and 9, the

section. shoulder 15 and also is spaced from the edge of the nib cavity. In the result, the nib cavity is bordered by a rib 30, which is an integral part of the section,` and the yoke embraces the rib along both sides and around its U-shaped inner end.

It will be apparent that with this arrangement the rib serves to insulate the nib from the reinforcing member and that the two may thereforebe of dissimilar metals..

Therib serves not only to insure against electrolytic action but also to minimize the danger of ink creeping back from the nib to the reinforcing member.

It will also be understood that the features and principles exemplified in the preferred form illustrated and described are susceptible of embodiment in numerous forms and combinations.

In the light of the foregoing the following is claimed:
