FEED FOB FOUNTAIN `PENS Application mea mgm 1e, mso. sex-m no. 475,690.

This invention relates to a novel and improved form of fountain pen, and more particularly, to a novel feed therefor. The invention Will be best understood from the fol- -lowing description and the annexed drawing, in which I have shown a selected embodiment of the invention, and in which:

Fig. 1 is a view of a fountain pen having the invention embodied therein; Fig. 2 is a view on an enlarged scale, showing a longitudinal section through the feed used in the pen of Fig. 1;

Fig. 3 is a view of the feed shown in Fig. 2, this view being taken from the top of Fig. 2; Fig. 4' is a vertical elevation of the feed appearing in Figs. 2 and 3 wi th the members constitutingthe feed partially disconnected;

Fig. 5 is a section on the line 5-5 of Fig. 2;l

Fig. 6 is a section on the line 6-6 of Fig. 2; Fig. 7 4is a view partly in elevation and partly'in section showing a different embodiment of the invention;

Fig. 8 is a View similar to i 4showing the embodiment appearing in ig. 7;

Fig. 9 is a section on'the line 9 9 of Fig. 7;

Fig. 10 is a view corresponding to Fig. 7 but showing still another invention; and

Fig. 11 is a view corresponding to Fig. 8

but showing the embodiment appearing in` Fig.1o. y

In prior art practice, the fountain pen feed is usually formed by a single-piece' of material having a channel formed by a groove in its upper face, this groove being closed by the pen proper. The upper end of the feed communicates with a sack or ink reservoir in which the ink is stored and from which the ink flows down the channel in the feed to a place beneath the pen proper.

When the pen is to be filled the lower end of the barrel must be immersed in the ink in the bottle before proper vacuum can be obtained to draw ink from-.the bottle through the channel into the sack.

According to my invention, I provide a channel having an mlet communicating with the sack much as before and having anl outlet beneath the pen proper but adjacent the point of the pen and spaced from the end of embodiment of the ldesignated 2. Inserted in the barrel is the usual pen proper 3 having a point 4. Beneath the pen is disposed the-feed 5, which is provided with a channel 6 communicating at its upper end or inlet 7 with avsack or ink reservoir 8 and having at its lower end an outlet 9.

The channel 6 may be formed in any suit*- able manner ybut for the purposes of illustration, I have shown it in the form of a groove in a member 10 which is slidably mounted in a tubular member l1 to which the sack 8 is secured. While the sack is shown as secured to the feed, it is, of course, understood that it may be secured to apart of the barrel as is also sometimes'done in this art. The upper part of the tubular member 11 forms a cover forthe channel 6, as plainly seen in Figs. 2 and 5, this top part terminating at the outlet 9. The outlet is formed partly by the upturned end 12 of the groove 6 and partly by the cut opening 13 at the end of the member 11. This outlet is covered by the pen 3, which extendsthereover and which is also disposed over the adjacent art of the 'cover and within the lower end 0 the -shown as used with these overflow pockets and while it is particularly advantageous with such pockets, the invention, of course, is not limited to a construction in which such pockets are used.

In operation, the ink will How down the channel 6 from the sack and will be dis? charged at the outlet 9 beneath the penpoint vus 5 the ink, this outlet now becoming an inletthrough which ink is drawn into the channel 6 and thus into the sack. Any suitable mechanism, such as commonly used with self-ill.

ing pens of this type, may be employed for causing the ink to be thus drawn into the channel 6 and into the sack.

It will be seen that it is entirely unnecessary to immerse the end 2 of the barrel. The pen may also be filled from a low supply of ink, which cannot be done with prior art constructions. By the word barrel` I refer to the part or parts forming the outer surface of the pen usually engaged by the hand and lingers of the user, and extending down to the penproper. Sometimes the lower end of the barrel isformed as a separate part secured to the upper part, and I intend the term barre as used in the cl/aims to embrace both of these parts when they are used.

Also, by 4this arrangement, it is unnecessary t0 have such a close fit between the pen proper and the feed, as it is where the pen is relied upon to form the top or cover of the channel in thefeed. Other advantages in this construction are the facts that when the pen is in use the ink will run directl to the pui point and there will be less lea age of I Referring now to Figs. 7, 8 and 9, I have shown therein a similar arrangement in which a larger outlet 9 is provided by making the end 18 of the member 11 terminate a greater distance from the end 19 of the groove 6 in the member 10. In this form the holes 17 in .the member 11 become open ended slots and the edge 20 of the part 1 1, which will thus be formed in several parts, abuts against the shoulder 21 of themember 10. Thls is closesimilar to what takes place in the form end 20 abuts a single shoulder 21.

In order to get a still largerv opening 9", the forms shown in Figs. 10 and 11 may be employed, in this form the pockets 15 being formed of larger portions or recesses and ben :smaller rtions of the holes 17 In ot er partie ars, the parts shown in. Figs. 7 to 11, inclusive, correspond closely to the parts shown in Figs. 1 to 6, inclusive, and .will not be further described.'

I claim:

l shown in Figs. 1 to 6, inclusive, wherein the part of the channel, a pen disposed over said uncovered partvof the channel, a sack communicating with the other end of the channel, and means formin a plurality of longitudinall vextending ucts in said channel ex'- ten ing from said sack Ato said lower end of the channel.

2. A self-filling fountain pen structure comprising a barrel having a feed projecting from its lower end, said feed comprising a over said cover, a sack communicating with the upper end of the channel, and means forming a plurality of `'longitudinally extending ducts in said channel extending from said sack to said lower end of the channel.

3. A self-filling fountain pen structure .comprising a barrel having a feed projecting from its lower end, said feed comprising a gmember having a channel, a cover tightly closingA said channel, said cover extending downwardly below the lower end of the barrel but leaving uncovered a part of the chan-` nel, the upper edge of said uncovered part being spaced from said lower end of the barrel, a pen disposed over said uncovered part of the channel and between the cover and the barrel, a sack communicating with the upper end of the channel, means forming a plurality of longitudinally extending ducts in said channel extending from said sack to said lower end of the channel, and overflow pockets formed in part of the recesses in said member and in part of holes in said cover.
