Ambition April 16, 1942, SGI'INQ. *39,220 I Y (ci. iet-109) 1 v 1e claim. This invention relates to an improved pen,
i particularly an improved pen point or nib.
It is an object of the invention to provide an improved pen point made primarily from plastic.
or other readily 'available material and which requiresa minimum amount of metal for its manufacture. v
A further object of the invention is the pro-y vision lof an improved pen point.or nib, of the g above charactenwhich is of relatively inexpensive construction, but which is, nevertheless, of attractive appearance and serves in a very satisfactory manner as va writing implement.
'In the accompanying drawing:

' Fig. 2 is a longitudinal sectional ,view on the line 2-2 of Fig. 1; i
Fig. 3 is a crosssectional view on the line 3- 3 Fig. 4 is an elevational view yof the metallic strip employed inthe pen pointl shown in Figs. 1 to3: Y
Fig.5 is an elevational view of 'a modified form of penpoint or nib embodying my invention, showing 'it from the concave side thereof;
Fig. 6 is a longitudinal sectional view on the line 6-6 of' Fig. 5; y l
Fig. 'I is a cross sectional view on the line 1-1 of Fig. 5;
Fig. 8 is-a longitudinal sectional view of a further modifled form'f pen point or nib embodying my invention; i f
Fig. 9 is a cross sectional view on the line 9-9 of Fig. 8; and
Fig. 10 is an elevational view of the metallic insert used in the form of pen point shown in Figs. 8 and 9.
Referring to the first four figures of the drawing, I have shown my invention as embodiedin a pen point or nib II of conventional shape and size. Thus, the pen point is made from relatively thin material and is of longitudinally bowed formation so as to have a convex and a concave side. At its lower portion, indicated at l2, the nib tapers towards a point, in the usual manner, while at its upper end it is formed into a shank adapted to be inserted in a pen holder or fountainpen barrel. My invention does not reside in the specific shape, size or appearance of the pen point, and this may be varied considerably.
In carrying out my invention., the principal portion or body of this pen point or nib, indicated projects beyond the lower end of the nib at theV central pointed portion thereof,` as indicated at IB. Inthe form of my invention shown in the first four figures of the drawing, the metal strip I5 is completely encased in plastic material, with the exception of the point I6 projecting beyond the lower end of the nib.
Adjacent its lower edge the penpoint is formed in the usual manner, with a longitudinal slit I1 terminating in an aperture I8, the slit and aperture serving to feed the ink towards the writing point and serving also as a reservoir for the ink. The slit and aperture I1 .and I8, respectively, extend not only through the plastic portion of the pen, but also through the metal strip, as shown most clearly in Fig. '4.'
y vThe pen point may be formed by moldingv the plastic portion thereof in a suitable mold. In this connection, the metallic strip I5 may be embedded in the nib by molding the plastic material around it or, if preferred, the Vplastic portion lof the nib may first be molded and thereafter the metallic strip may be inserted into a longitudinally extending aperture provided in the central portion of the nib. Under any circumstances, the metal strip I5 should be firmly held in the plastic portion of the nib so as to prevent relative movement between` the parts. When the plastic portion is moldedaround the metal strip, the parts are retained against relative movement by the adhesion and frictional engagement between the strip and plastic material. When the strip is inserted through an aperture provided in the plastic material, the strip may be held in position either by means of a tight frictional engagement between the strip and the material, or by meansof cement or the like.
The completed pen may be employed in the usual manner. Thus, where it is used in connection with a fountain pen, it is inserted in a foun-l tain pen barrel and the ink willfeed downwardly from the ink feeder, through 'the aperture I8 and slit I'I, tothe projecting point I6. Although use in connection with fountain pens, it will be appreciated that it may also be inserted in the conventional type of pen holder and used in the conventional manner by dipping the point into ink.
The projecting portion I6 is tapered and shaped into a satisfactory writing point, as shown. The strip I may be made from any desired type of metal, although it is preferably made of metal which will resist the corrosive action of ink, such as the noble metals (i. e. gold, platinum, or silver) or stainless steel. Where a soft metal is employed, the projecting point I8 is preferably tipped with a hard metal, such as iridium.
Referring now to the form of my invention shown in Figures 5, 6 and 7, it will be seen that I have provided a pen point or nib I8, similarin shape and appearance to the nib and in which the principal portion or body of the nib, indicated at 20, is likewise made of a similar type of plastic material.
Extending longitudinally of the central portion of the nib, I also provide a metallic strip 2| resembling in vmany respects the strip I5 and constructed of similar material.
bedded in the plastic material in the manner of the strip i5, -is exposed on one of the surfaces thereof, in the instant embodiment, on the inner or concave surface. To firmly retain the strip l2| in the plastic material, it is preferably ared outwardly on its inner surface, as shown at 22, with the plastic material embracing and engaging the flared portions.
As in the first form of my invention, strip 2| projects beyond the lower` portion of the nib, as shown at 23, and the nib is provided with an upwardly extending slit 24, terminating at an aperture 25. 'Ihe nib shown in Figs. 5 to '1 may be formed by molding the plastic portion in a suitable mold, and the strip 2| may be secured in position eitherby molding the plastic material around'it, in the manner shown, or by inserting .the strip into a slot of mating configuration formed in the plastic material. Regardless of the manner in which the nib is formed, the metallic strip 2| should be firmly held in position against accidental displacement.
The plastic and metallic materials-employed in manufacturing the second form of my invention may be similar to those employed in the first form of my invention, and the nib is used in a similar manner.
Referring to the form of my. invention shown in Figs. 8, 9 and 10, it will be seen that I have provided a pen point or nib 26 having a central cylindrical portion 21 terminating in a truncated conical portion 28 at'its lower end, and in a truncated conical portion 29 at its upper end. The portion 29 serves as a shank which may be fitted into the barrel of a fountain pen or into a' pen holder. The portion 26 tapers towards asuitable writing point.
The principal portion or bodyof= the nib 26 is formed of plastic material similar in character to the plastic material employed in the first two forms of my invention, and extending longitudinally ofthe body portion through the center thereof, is a duct in which Iprovide a metallic member 30 which serves as an ink feed. The metallic member or feed 30'consists ofa plurality of strands of wire, twisted together, in the .manner shown in the drawing, in which three strands are illustrated, The metallic member or feed It will be seen 'that the strip 2|, instead of being completely emever, I prefer to use the metals listed above in connection with the strip I6.
Due to the fact that small interstices are provided between the strands of metal which are twisted together, in the manner shown, and between the strands and the adjacent sides of the duct extending through the plastic material, the metallic member serves as an ink feed, and ink can be fed downwardly along the member 30 from the upper end of the nib to the projecting loop 3|. Due to this fact, the nib 26 may be inserted -directly in a fountain pen barrel and ink from the fountain pen reservoir will feed downwardly through the metallic feed to the writing point.
The plastic portion of the nib, shown in Figs. I
8 to 10, may be molded in a suitable mold and the metallic member or feed 30 may then be inserted through a central bore provided through the plastic portion. In vthis connection there should be a tight frictlonal engagement between the metallic feed and the plastic portion of the nib in order to prevent relative movement of the parts.
From the foregoing description of several embodiments of my invention, it will be seen that my improved pen'point or nib is made primarily from plastic material or some other material which is readily available and that the pen point or nib requires only a minimum amount of metal.
tion projecting beyond one end or nib is of relatively inexpensive construction.
but yet is of attractive appearance and serves very satisfactorily as a writing implement.
It should be understood, of course, that modiiications may be made in the illustrated and described embodiments of my invention without departing from the invention as set forth in the accompanying claims.
