This invention. relates to an improvement in feed for self-fillingv fountain pens.

In all or nearly all self-filling fountain pens heretoforemade, so farl'as known to me, in order to fill the ink sac ofthe pen it has been-necessary to dip not only the pen but the end ofthe holder as well into the ink during the'filling and this necessitates wiping the ink from theholder after it is filled. One object of the present invention" isto provide such a construction that in order to fill. the ,penyonly the projecting portion of the feed which extends beyond the holder need be immersed in the inkv without imm'ersing any. part of the ho-lder itself.-

In allother self -fillin-g-fountaintpens heretofore made so far. as known to mezthe feed 1 has been provided with'two'ink passages through one of whichthe ink isdrawn into the holder 'or' sac during the fillingof the pen and through :thia other of which the ink "flows from the-sac to'the pen point or nib when the penis used inwriting. 1 2

'One object of. hepresentnvention is to sage" through which" from the reservoir Writing.

Another feature of the invention consists in the construction of the feed with a transverse groove to provide the vent whereby the ordinary vent hole in the nib of the pen may be dispensed with. I I

to the nib of the pen when Before explaining 1n detail the present in -j vention, and the method or mode of operation embodied therein, it is to be understood that the invention is not limited in its application to the details of construction and arrange ment of parts illustratedinthe accompanyor carried out in various -:ways. I- Also is to be understood that the tphraseology or terminology employed herein-is for the purpose l ofdescriptionand notof limitation, and it 1 I tudinal groove or depresslon22in,the face; of I :thefeed: The only outlet from saidwpassage is not intended to-limit the invention beyond the terms of the several claims" hereto ap-' l In the drawings:

The feed whihf isthe speciallsubject of Prefv erably the feed is a unitary structure; f The I '20 of the feed is cylindrical and is of somewhat less'dia'meter than the {outer portion of the'bore of the'pen section-'14 so i that when the feedis inserted in the end of;

section 1%}: "tliere willfbe a thin 'space 'asshown at'19 between the,peripheryof the 1 feed and the inner periphery of the pen sec? tion. The inner end portion 19? of thebore of the pen section is'of le'ss diameter than the" outer portion thus. forming: a shoulder 20? Y which servesas a seat for the rearend of the feed.

A transverse semi-circular groove '25 crosses the longitudinal depression 22 slightly forward of the outlet aperture 24: and extends around to the flattened lower side 21 of the feed. The groove 25 thereforev communicates through depression 22 with the outlet aperture 24 of the longitudinal passage 23, 23? in the feed.

7 Preferably the forward portion 23 of the passage 23 is reduced in diameterfrom that of the rear portion as will be seen from the drawings.

The shank portion of the pen B should be inserted in the thin space between the projecting portion of the convex side of the feedand the inner wall of the pen section 14 as clearly 'shown in Fig. 1. p

The nib end of the pen is formed with the usual split 26, and when the pen is inserted this split intersects the transverse groove 25 and thelongitudinal depression 22 of the feed. By reason of the transverse groove 25 suflicient ventis givenfor the feed so that the hole usually formed in the nib of i the pen-connecting with the: longitudinal split may be entirely omitted V lVhile I have shown and described one form of holder and barrel of a fountain pen, it is to be understood that this is illustrative of one form only and that the invention is not limited to use with that particular type of holder. Any other suitable form of holder for use withthe feed described may be em- I ployed.

What I claim isz V .1. .A feed for a fountain pen of the self- 'filling type having a longitudinal passage open atthe rear end of the feed and extend- .ing wholly-within the wall" of the feed until it reaches a point somewhat back fromvthe forward end ofthe feed, thence turning laterally and opening out through the pen supporting side of the feed, the said feed being upper faceintersecting saidoutlet from the longitudinal inside passage, said longitudinal recess being walled at its sides and ends, said feed being formed witha flattened underface oppositesaid recess and being also formed with a transverse peripheral groove extending'from bothsides of said longitudinal recessto the outer edge ofthe'flatted underside i of said feed] r 2. ;A fountain pen of the self-filling type ,having a barrel, a tubular pen section connected withthefront efndof the barrel, in combination Witha f ed member connected assa 'ein said en sectionfand extendin .b \J

--forward wholly within the wall of the feed until it reaches a point somewhat back from the forward end of the feed member, thence turning at an angle and opening out through the pen-supporting side of the feed at some distance back from the forward end of the feed, the face of the feed on the pen-supporting side having a longitudinal depression into which said outlet, from said longit nal passage opens, said feed having a rare groove which intersects said longitudinal depression and is open at its ends, said longitudinal depression being walled at both ends and at its sides except where it intersects said transverse groove, said transverse groove constituting the ink inlet in filling the pen. 7

3. A fountain pen of the self filling type having a barrel and a tubular pen section connected with the front end of the barrel, in combination with a feed member connec the forward end of the feed member, thence turning at an angle and opening out through the pen-supporting side of the feed at some distance back from the forward end of the feed, theface of the feed on the pen-supporting side 7 having a longitudinal depression into which said outlet from said longitudinal passage opens, said feedhaving a transverse groovezwhich intersects said longitudi naldepression and is open at its ends, said depression being walled at both ends and at its sides except where it intersects said transverse groove,.the ends of said transverse groove being spaced apart from each other and open to the air,said transverse grooveconstituting the ink inlet in filling the pen. In testimony whereof I aflix my signature.
