FOUNTAIN PEN Filed Dec. 51, 1942 I INVENTOR CZ/A/TO v MIR5HAL L Patented July 13, 1943 UNITED STATES PATENT OFFICE 17 Claims.
' by suitable reference characters in each of the views; and in which:
Fig. 1 is a diagrammatic sectional view of the writing end portion of a fountain pen, showing a penpoint and feed in elevation.
Fig. 2 is a top plan View of the penpoint or nib.
Fig. 3 is a bottom plan view of the structure shown in Fig. 2.
Fig. 4 is a top .plan view of the feed shown in Fig. 1.
Fig. 5 is a longitudinal sectional view through a penpoint and feed, showing a modification.
Fig. 6 is a bottom plan view of the penpoint shown in Fig. 5.
Fig. '7 is a view similar to Fig. 5, showing a modification.
Fig. 8 is a plan view of the feed, as shown in Fig. '7, and
Fig. 9 is a bottom plan view of the tip end portion of a penpoint or nib, showing another modification.
In the construction of penpoints or nibs, particularly as used in fountain pens, it has been a common practice to employ various types and kinds of metals or combination of metals, par ticularly with respect to the tip ends of such pens in producing the desired results and to care for the wear to which the penpoint is subjected.
It is the purpose of my invention to provide a penpoint or nib which is entirely composed of glass, thus providing a penpoint or nib which will have the required hardness and also possess the property of providing free fiow of ink, and also eliminating any possible corrosion or de terioration of a metal as is commonly experienced with other types of metal pens.
My invention also comprises the use of a feed in conjunction with the penpoint which may also be composed of glass or suitable plastic material. In both instances, that is to say, both the penpoint and the feed are made substantially half round in cross section so that collectively, these members may be made to fit snugly within the feed section of the fountain pen and may be quickly and easily removed therefrom.
In Fig. 1 of the drawing I have diagrammatically illustrated at III a part of the feed section of a fountain pen, in the bore H of which is frictionally supported a penpoint or nib I2 and a feed l3.
The nib 12, as seen in Figs. 1 to 3 inclusive comprises an elongated half round strip of glass, the lower surface 14 of which is fiat, and has at the outer end portion thereof an elongated feed groove 15 which terminates at the writing end I6 of the nib. The point of the nib is formed by bevelling the side walls as seen at H to form the point l6 and also by an abrupt bevel l8 at the top of the nib which joins the rounded contour in a slightly bevelled portion Ill.
The pointed end 16 may be rounded to provide the desired writing surface, and as seen in Fig. 9, the feed groove 20, which is equivalent to the groove 15 may be contracted at the pointed end 2i of the nib, as seen at 22, particularly where it is desirable to form a finer writing point. At this time it will be understood that the illustrations in the accompanying drawing are more or less diagrammatic for sake of clarity, but in all cases, the required feed groove and point construction will be provided.
In the construction shown in Figs. 1 and 4, the feed I3 is provided with a feed groove 23, which extends from the inner end 24 of the feed to a point 25 short of the contracted end 26 of this feed. The contracted end is formed by bevelled side walls 21 and a bevelled end wall 28. It will be understood that the feed l3 may be adjusted to different positions longitudinally with respect to the nib l2 in setting the end 26 to the desired position with respect to the point IE5 at all times. However, necessary clearance will be provided for free exposure of the point to the surface over which the pen is moved.
The penpoint or nib is also preferably provided with means for venting the pen and to this end a vent passage 29 is provided on the surface M which opens through the inner end of the pen in a groove 30 and outwardly to atmosphere beyond the section In through a groove 3| which joins the chamber 29 through a .port 32.
In Figs. 5 and 6 of the drawing is shown a slight modification of the structure shown in Figs. 1 to 4 inclusive in which the feed section I3 is the same as that employed in the other figures, but the nib 33 differs from the nib [2 in that a well portion or chamber 34 is formed in the feed groove 35 inwardly of the pointed end 36 of the nib, but in position to register with the end 25 of the groove 23 of the feed.
In Figs. '7 and 8 of the drawing is shown another modification wherein a nib similar to the nib 33 is employed, and substituted for the feed l3 is a feed 31, the groove 38 of which terminates at its outer end in a well or chamber 39 similar to the chamber 34, and registering or substantially registering therewith, depending upon the adjustment of the feed with respect to the nib.
The purpose of the well or storage chambers 34, 39, is to provide at the pointed end portion of the penpoint or nib a fairly large supply of ink which will deliver the ink more freely to the writing point, particularly with some types and kinds of inks, and with penpoints of the finer writing points.
In the structure shown in Figs. to 7, the penpoint or nib 33 also has an air vent chamber 40, similar to the chamber 29 which opens through the inner end of the nib in a groove 4! and to a groove 42 on the top surface of the nib through a port or passage 43. I
The port 43 is preferably arranged at an angle, as clearly illustrated in Figs. 5 and 7 in order to prevent discharge of ink particularly in the agitation of the pen, While the venting has been illustrated as part of the nib-construction, it will be apparent that the same general structure is applicable to the feed for accomplishing the same results.
