v 2 Claims.
'This invention relates in general to fountain pens and particularly to the ink feed, the pen 'point and means for mounting the latter.
The use of gold in pen points or nibs is highly vdesirable because of its non-corrosive character used in pen points", particularly for low cost fountain pens. n
In my United States Patent No. 1,989,220, dated January 29, 1935, I described and claimed va gold Other objects, advantages andvresults of the invention will be brought out by the following description in conjunction with the accompanying drawing in which Figure 1 is a, top plan view of a fountain pen -and its softness and flexibility which contribute embodying my invention with portions of the to ease of writing. Because of its high cost and pen casing broken away and shown in section. the present restrictionsvupon its use due to the Figure 21s a side elevational view thereof. war, it is necessary that a minimum weight of Figure3is a'vertical longitudinal sectional view gold consistent with satisfactory operation be through the fountain pen on the line 3-3 of Figure 1.
Figure 4 is a similar view to Figure 1 showing amodification of the invention.
Figure 5 is a side elevational view of the pen nib, or pen, of high carat content but of finer or shown in Figure 4 with portions shown in verthinner gauge than present day nibs of corretical longitudinal section on the line 5-5 of Figsponding size, so that the amount or weight of ure 4. gold therein is appreciably smaller as compared Figure 6 is a top plan viewV of the nib holding with the usual gold nibs, combined with novel and ink-feed section of the pen showing modinib reenforcing means comprising a metal frame mations of the invention. for preventing the nib from buckling or unduly Figure '7 is a vertical longitudinal sectional flexing under Writing pressure. l view on the line 'i-'l of Figure 6. v HOWCVGI.. it is now desirable if not necessary Figure' 8 is a fragmentary enlarged vertical to further reduce the amount of gold allOY and longitudinal sectional view similar to'- Figure 5 also the amount of any other metals, used in showing the invention applied to a known type constructing -pen nibs, and therefore one object of fountain'pen, of my invention is t9 provide a pen nib that shall Figure 9 is a top plan View of the 1nkfeed bar be `much smaller and contain less metal than and` Pen mbs of the past in combination with novel 30 Figure 10 is a transverse vertical sectional view and improved means formed of plastic material on the une n n of Figure 9. l t0 tak@ the Place 0f the metal reen cmg ffamf" specifically describing the embodiment of the shown in my aforesaid patent, for reenforcing the invention illustrated in Figures 1 to 3 inclusive, gibkgurmg wriilg opatigrdueggg the reference character I designatestthe per; c ng or un e ex barrel in one end of which is fitted in he usua in'lplhissmt nib smaller gives rise to new prob 35 manner' a' tubular section 2 vhiclnhstn fr); a ng e tension 3 within the barrel o w c e lems in the feeding of ink to the mb' particularly sac 4 is connected to serve as an ink reservoir. i venting Squirting or excessively rapid now Within the other end of the section 21s fitted a Ofmlclkihgrieattitlssnhgnal'ei 40 combined nib-holding and ink-feeding unit 5.

The nib preferably is formed of an alloy of tip as shown in Figures 1 and 3. In other words,
a portion of the tip overlies substantially the whole of the pen nib in contact therewith so that the latter is reenforced and prevented fromy buckling or unduly flexing under writing pressure. To provide clearance at the underside oi the pen nib for writing operations, i. e., to prevent contact of the tip 8 with the surface being inscribed with the pen, the outer extremity of the tip is beveled as indicated at I4. More specifically the tip 8 is frusto-conical and coaxial with the-barrel I, with the plane of the end I4 inclined to the axis of the tip.
To ensure proper supply of ink from the reservoir 4 to the pen nib, the feed bar I I has a longitudinal ink feed groove I5 that communicates at one end with the reservoir and at the other end with the usual hole I6 in the pen nib at the base of the slit |30 in the writing point of the nib; and the portion of the tip 8 that overlies the pen nib has an opening I1 that registers with the opening I6 to act as a breather for facilitating flow of ink through the channel I5. This opening forms in effect a cross bar |10 that traverses and contacts with the topl surface of the nib between the hole I6 and the extremity of the writing point.l
Should ink flow too rapidly or in excessive quantity through the channel I5, the ink will pass through the slit in the writing point into contact with the underside of the bar |10 which by surface attraction will cause quick spreading of the ink and accumulation thereof in the hole I1 which thus serves as a trap, thereby preventing squirting or leakage of the ink at the nib.
During writing operations a quantity of ink will accumulate in the opening I1 and form an auxiliary ink reservoir to ensure constantly adequate ink at the nib point for beginning writing operations without shaking of the pen to'start flow of the ink.
It is also desirable to provide another auxiliary reservoir to constantly maintain adequate amount of ink at the writing point, and as shown the shank 6 of the body part of the unit 5l has a plurality of transverse slots I8 which establish communication between the reservoir I and the groove I5. Ink will accumulate in these slots so as to be ready to flow quickly upon starting of writing operations.
Also, preferably the underside of the feed bar I0 is cut away as at I9 to provide another auxiliary reservoir or trap between the said bar and the body part of the unit 5.
In addition to ensuring adequate supply of ink to the pen nib, the slots I8 and the reservoir formed by the cut away portion I9, will serve'as traps to prevent squirting or excessive rapid flow of ink to the pen nib.
This structure will avoid the necessity of the special caps now utilized for fountain pens to prevent leakage of ink from the pen point into the pocket or container in which the pen may be carried.
In Figures 5 and 6 I have shown the shank 8 of the body part of the unit 5 formedwith a plurality of circular openings 2Il'instead of the slots- I8, to serve as auxiliary reservoirs. v
As shown in Figures 6 and 'I the auxiliary reservoirs like I8 and 20 may be omitted, the shank 6 being devoid of lateral openings.
In Figures 1 to 3 inclusive I have shown the combined pen holding and ink feeding unit 5 used in conjunction with a section 2 of special shape, while Figure 8 shows the tip applied to a regular section 22 such as commonly found in fountain pens; but if desired the unit 5 may be used in fountain pens that do not include such sections, for example as shown in Figures 4 and 5 where the unit is illustrated as directly fitted into the end of the fountain pen barrel 2 I. This type of structure is generally found in pens that have pumping mechanisms for drawing ink diirectly into the barrel, as distinguished from pens having rubber sacs for containing the ink.
In Figures l'to 3 inclusive I have shown the unit 5 screw threaded into the section 2, but obviously the unit may be frictionally fitted and adhesively secured in the section or pen barrel as shown in Figures 4 and 5;
While I have described the preferred and other embodiments of my invention, it will be understood that many modifications and changes in the details of structure of my invention may be made by those skilled in the art without departing from the spirit or scope of th' invention.
What I claim is:
1. A fountain pen including a barrel having an ink reservoir, and a nib-holding and inkfeeding unit comprising a body part secured in one end of said barrel and having an opening therethrough communicating with said reservoir, an ink feed bar fitted in said opening, a pen nib secured between the walls of said opening and said feed bar and having a writing point with a longitudinal slit, there being an ink feed channel leading from said reservoir to said slit, and said body part having a portion in overlying contact with said writing point and provided with an opening to receive and hold ink from said slit.
2. A fountain pen including a barrel having a reservoir, a nib-holding and ink-feeding unit comprising a body partv secured in said barrel and having a longitudinal opening therethrough communicating with said reservoir, an ink feed bar fitted in said opening, a nib having a writing point with a longitudinal slit, said nib being secured between said feed'bar and the walls of said opening with the extremity of said writing point projecting from said body part so that the major portion of said writing point is overlaid by and in contact with a portion of said body part whereby said writing point is reenforced against buckling under writing pressure, there being an ink feed channel leading from said reservoir to said slit in said nib, and said portion of the body part that overlies said writing point of the nib having an opening communicating with said slit in the nib and with the atmosphere.
