Marshall, Bronx, N. Y. Application December 31, 1942, Serial No. 470,877 17 Claims. (Cl. 120-43) This invention relates to pens and similar within the feed section of the fountain pen and writing implements. More particularly, the in may be quickly and easily removed therefrom. vention relates to a penpoint and feed for use In Fig. 1 of the drawing I have diagrammati in fountain pens wherein the penpoint is formed cally illustrated at III a part of the feed section from clear or colored glass. The novel features of a fountain pen, in the bore H of which is of the invention will be best understood from frictionally supported a penpoint or nib I2 and the following description when taken together a feed l3. with the accompanying drawing, in which cer The nib 12, as seen in Figs. 1 to 3 inclusive tain embodiments of the invention are disclosed, comprises an elongated half round strip of glass, and in which the separate parts are designated 10 the lower surface 14 of which is ?at, and has at ' by suitable reference characters in each of the the outer end portion thereof an elongated feed views; and in which: groove 15 which terminates at the writing end Fig. 1 is a diagrammatic sectional view of the I6 of the nib. The point of the nib is formed writing end portion of a fountain pen, showing by bevelling the side walls as seen at H to form a penpoint and feed in elevation. the point l6 and also by an abrupt bevel l8 at Fig. 2 is a top plan View of the penpoint or the top of the nib which joins the rounded con nib. tour in a slightly bevelled portion Ill. Fig. 3 is a bottom plan view of the structure The pointed end 16 may be rounded to provide shown in Fig. 2. the desired writing surface, and as seen in Fig. Fig. 4 is a top .plan view of the feed shown in 20 9, the feed groove 20, which is equivalent to Fig. 1. the groove 15 may be contracted at the pointed Fig. 5 is a longitudinal sectional view through end 2i of the nib, as seen at 22, particularly a penpoint and feed, showing a modi?cation. where it is desirable to form a ?ner writing Fig. 6 is a bottom plan view of the penpoint point. At this time it will be understood that shown in Fig. 5. 25 the illustrations in the accompanying drawing Fig. '7 is a view similar to Fig. 5, showing a are more or less diagrammatic for sake of clarity, modi?cation. but in all cases, the required feed groove and Fig. 8 is a plan view of the feed, as shown in point construction will be provided. Fig. '7, and In the construction shown in Figs. 1 and 4, Fig. 9 is a bottom plan view of the tip end 30 the feed I3 is provided with a feed groove 23, portion of a penpoint or nib, showing another which extends from the inner end 24 of the feed to a point 25 short of the contracted end 26 of modi?cation. this feed. The contracted end is formed by In the construction of penpoints or nibs, par bevelled side walls 21 and a bevelled end wall 28. ticularly as used in fountain pens, it has been a It will be understood that the feed l3 may be common practice to employ various types and adjusted to different positions longitudinally kinds of metals or combination of metals, par— with respect to the nib l2 in setting the end 26 ticularly with respect to the tip ends of such pens to the desired position with respect to the point in producing the desired results and to care for IE5 at all times. However, necessary clearance the wear to which the penpoint is subjected. 4.0 will be provided for free exposure of the point to It is the purpose of my invention to provide the surface over which the pen is moved. a penpoint or nib which is entirely composed of The penpoint or nib is also preferably pro glass, thus providing a penpoint or nib which vided with means for venting the pen and to will have the required hardness and also possess this end a vent passage 29 is provided on the the property of providing free ?ow of ink, and 45 surface M which opens through the inner end also eliminating any possible corrosion or de— of the pen in a groove 30 and outwardly to at terioration of a metal as is commonly expe mosphere beyond the section In through a groove rienced with other types of metal pens. 3| which joins the chamber 29 through a .port 32.

In both instances, that is to say, both I3 is the same as that employed in the other the penpoint and the feed are made substan ?gures, but the nib 33 differs from the nib [2 in tially half round in cross section so that collec that a well portion or chamber 34 is formed in tively, these members may be made to ?t snugly 55 the feed groove 35 inwardly of the pointed end 2 2,324,008 36 of the nib, but in position to register with of said body, and the ?at surface of said body the end 25 of the groove 23 of the feed. having means extending longitudinally there In Figs. '7 and 8 of the drawing is shown an of for feeding ink to said point. other modi?cation wherein a nib similar to the 5.

A pen point for writing implements, com In the structure shown in Figs. 5 to 7, the pen prising an elongated body composed entirely of point or nib 33 also has an air vent chamber 40, 20 glass, said body having a ?at surface extending similar to the chamber 29 which opens through throughout the length thereof and a convex the inner end of the nib in a groove 4! and to surface,'one~ end of said body being shaped a groove 42 on the top surface of the nib through ‘to form a writing point terminating at the flat a port or passage 43. ~ ' I surface of said body, the ?at surface of said The port 43 is preferably arranged at an angle, body having means extending longitudinally as clearly illustrated in Figs. 5 and 7 in order thereof for feeding ink to said point, a feed to prevent discharge of ink particularly in the member arranged directly upon and extending agitation of the pen, While the venting has been longitudinally of the ?at surface of said body illustrated as part of the nib-construction, it will andhaving means cooperating with said ?rst be apparent that the same general structure is named means in controlling feed to the point of applicable to the feed for accomplishing the same said body, and means for venting the ink flow to results. said ?rst named means and member.
