SELF-FILLING FOUNTAIN-PEN.

.To all whom it may concern:

Beit known that I, JULius L. SCHNELL, a

Y. citizenQ'of the'United States, residing at specification.

.contemplates -the use 'of but. ir singlel'ring or. collar lying snuglyv about `the barrehandj 'ha-ving' butone slight projection or enlarge.; mentat one side, the ring being s o associated with the remaining elements *of Athe filling mechanism that the ring must be turned 'about thebarrel'to an appreciable extent b e- .-,Qforc the flexible ltube is compressed to'expel 'the ink or air therefrom prior. to the refilling of the p'en. v 'Further,.the .ring or` sleeve Arlington, in the count-yof- Hudson and State of .New1 Jersey, have invented new' and 'useful Improvements i n ASel -Fi1l in'g F ountain-Pens, of which the following is a This invention .relates to fountain pens of lthe self-filler type, and has particular' reference to certain improvements in pens 'ofthe character having'a collapsible' inkreceiving tube in the barrel adapted todraw.

in the ink by the expansion of the'tube.

It is one of the objectsof'this' vention to overcome this difficulty 'byso peculiarly forn'iing. the operative parts o'the pe that `fi -tliey and which'are so arranged'and formed thgit an accidental discharge of the inkvis practically impossible.:

is .so peculiarly formed that v,it can be turned in but onedire'ct-ion. andicannot be moved 'in- 'so that a is practically' impossible for the fingsrs grasping ythe `barrel to accidentally col '-pse the'tube and discharge the ink. y

'07' Another object *ofthis inventionI is to provide. afilling mechanism which vis automatic i-nreleasing the flexibletube irrespective of the slow or quick turning of the ring.

l It has been found that the most desirable results obtained in fillngcollapsible tubes of this nature isin releasing them suddenly and i permitting their sudden expansion'whereby the tubes are iuorecompletely 'filled than by Vallowing th'eni to expand slowly. The ring of this invention isv provided with novel means for suddenly releasingthe tubeafter the ring has completed a predetqjmined turning movement, even if the ring is'fslowly turned.

vA further feature of this invention is in providing avisual indication of the com- -Specication of Letters latent.

Y i pletion ofthe `predetermined turning movement of :the ring, or when the tube is released.

The invention also embraces a novel means for insuring the expulsion of the air or other fluid from the tubewl1en the ring isturned.

Other objects and advantages of this invention will be more particularly pointed out in the following specification of the embo'diment of the invention illustrated in the accompanying drawings.

In t e drawings: F'gure 1 is a side eleva` tion of the improved self-filling fountain pen. Fig. 2 is a longitudinal section through the same. Fig. 3 is a transverse section on the line 3-3 of Fig. 2. Fig. 4 is a similar view showing the parts adjusted to collapse Athe flexible tube preparatory to filling the pen. Fig. 5 is a detail erspective view of the presser bar employe Fig. 6 is a longitudinal section through the pen showing in normal .position the operative lparts andv a modified form of the presser bar. Fig. is .asimilar view-disclosing the `parts moved into the position to `collapse the tube. Fig. 8 is a transverse section similar to Fig. 3 disclosing aslght modification in the operating ring. Fig. 9 is a similar view dis` closing. a further modified form of the operating ring. Fig. 10 is a detail perspective view of the modified form of presser bar disclosed iii Figs. 6 and 7.

Referring to the drawings, in which simi- .lar characters of reference indicate like parts throughout the several views, 13' designates the barrel of the pen provided with the pen ,'section, pen point and cap in the usual inannei. \V1thin the barrel 15 is located a flexiblctubc 16 having suitable' connection with ink carried by the pen. lVithin the barrel 15, and at-one side is located a longitudinal presser bar 1 7 lying against the tube 16 throughout practically its entire length and having intermediate its endsl an outwardly extending pin 18. The barrel l5 provided at one side with a small opening through which extends, and through which is adapted to slide, the pin 18 in moving the presser bar 17 against and away from the colla psi ble tubelG.`

,The barrel 15 has .an annular depression its ends, through which the pin 1S projects at one'sidc of the barrel, the annular groove of the barrel receiving a closely fitting ving or groove in-its outer surface intermediate the pen section and adapted to receive the 19 lying substantially flat 'againslt the balrel. The ring 19, as may be best seen from F'gs. 3 and 4, is provided at one side with an enlargementor projectionO presenting opposed flat faces 91 for a )ui-pose hereinafter pointed out. lVitliin t ie enlargement 20, and at one side of the saine, is formed a groove 22 of a width sufficient vto receive the pin 18 and having an inclined .w'all eecentri'c to the axis of the ring 19 and serving asa Icani for operation avainstl lthe outer end of the pin 1S to move the pin throughrthe side ofthe bai'rel 15 when the sleeve is rotated. The

projection .20 is provided at its opposite side -with an abrupt or sharp shoulder 23 adaptedrto suddenly release the pinx18'1after the same has been compressed against the inner wall nf the sleeve 19 when the ,sleevefis moved into normal position, as disclosed in Fig. 3. Normally the pin 18 is extended and rests in the outer removed-end ofthe groove 1 groove 2 2.

22, and .for the purpose of giving a visual indicationfof such positionof/the 'pin 18, the projection 20 is provided wi'tlra small opening 244th'roiigh whichfinaybe' readily seen the outer end of the pin 18, the'f'opening 24 registering with the outer end 'of' the In Figs. 0,.'7 iid io niet@ is 'ai'sfitsed a slight modification in the yform of' "presser lbar. From Fig. 10 itwill be seen that-.the presser bar 17?. is enlarged at its innerend,`

and is given substantially wedge-shape'lso that the loiver surface o f the presser 'liar 17 is incline.; toward the tube at its innerend. It is notl necessary. that this'presserbar be of solid constructioiias disclosed: in the drawings, but it in ay be formed in any suitable n'iaiiner with an inclined face vfoifper forming the functions ascribed to thisparticular presser bar. \V heu the 'messer bar 17a is in no'rmal -position, as t presser bar. is removed slightlyfrom the tube.` Vlieii the pi'csseiba r is ui'oved inwardly hy the ring 19 the upper end of the tube is first compressed and the fluid is expelled from that end prior to the compression of the lower end of the tube. Since the face is. iuclined the tube is compressed frouiilsuppcr to its lower end gradually, thus 'insuringr l'h e isclosed iii Fig G, the upper end thereof is in contact' with the tube 1G, while the lower end offihc.

1S. The projection 20 is providediiwith op- )osed shoulders 23" n is adaptedjo move when the ring\"\`l9"' is turned to compress or releasethe p1i`i`i\ `-The outer end or top .of the projection 20"`is pro` vided with an indicator opening 24F through -adapted, to receive the outer end of the pin against vfhi'chtlie pin 18 which may be seen the upper end of pin 18 when the same is extended, or in norefial position. "lien it. is desired `to fill the pen, the bargrasped in the opposite hand. The flat sides :21,provide gripping surfaces 4for the'findrs in holdin" and turning the sleeve '19.*I-lie Sleeve 19 is rotated to'move the shoulder relis grasped in one hand and the ring 19"= is away' `from the pin 18 whereupon the cam'r wall of the groove 22 vis moved against the end of the pin 18 .and effects the gradual depression of the pin into the barrel 15.3" As the pin l18 ismoved inwardly the presser bar '17 is forced against the flexible tube 16 and l(.ollapse'stlie same,'expelling the air or other fluid from the tube. The pen sect-ion is nowT insertedinto la quantity -of ink, and the sleeve19 `is'furthe'rrotated in the -samedi'- rect-ion until the endof the pin 118 (passes-the shoulder 23'.-` The pin 18 is now su denly released from the shoulder 23 and springs out^V wardlyunder .the pressure -of the tube 16 into'the'outer end ofthe groove 22. This sudden releasing 'of the pin 18 admits ofthe suddenexpansion of the'tube 16 whereupon the ink is Adrawn through the pensection and- .up into the flexible tube, nearly lfilling the' same. v As soonas the pin 18 is released from `the shoulder 23 -itisiiaps up into the outer end of thev groove 22 and mafv be seen through the indicator 'opening 21.'. lVlien the pin is tliusseeii at this opening, t.he user under.- stands that tlie tube lil is expanded and that the pen lis filled. 3

lf desired, the indicatoi` opening 24 may be done away with, as is disclosed in the structure of Fig. 8. The .snapping of the pin into normal position when released fromthe shoulder 23 in this case is deemed suflicient to give notice that the tube is expanded to its fullest. extent.

ln the modification shown in Fig. 9, the

projection 20" of the'ring A19 .is provided* with a pair of shoulders .23". both-of which are somewhat- 'graduah and which admitr of vtheturning'of the sleeve 19" in either direction. 'ljVlien the pin 18 is extended 011t- -wardly from the barreliin normal?position,v

such position may be readily ascertained by observingthe vpointofthe pin 18 against or at the inner end of the opening 24".

The modification thleJ presser bar is disclosed in Figs. -6,7 audio," the latter figurev showingin detail the structure ofthe resser -b'ar-17*L which has an inclined face W ereby oneend of the presser babeomes into contact with the side of the tube before its`oppsite f 1,060,137Y A, 4- g end, and wherein the tube'is Hat-tened gradul ally from its inner end to its outer end. The presser bar 17 is held with its outer face in parallelism with the sideof the barrel 15 by the pin 18, the latter being guided in its movement .from wabbling or canting in the groove 22. of the projection 20 which is car ried uponthe closely fitting sleeve or ring 19. Vhen the pin 18 is moved inwardly from the groove 22 the frictional contact between the inclined face of the presser bar 17' and the side of the tube prevents the presser bar 17* from slipping'or cant-ing. It. is thus seen that during the entire movement of the presser bar 17 its inner face is presented at4 all times at an inclination to the axis of the tube 16, andthat the air in the tube is driven "from end to end in the tube as the latter is collapsed. As the presser bar 17 is moved inwardly by the turning of the sleeve 19 the frictional contact between the presser bar 17 and the adjacent side of t-he collapsible tube v16 increases. Since the presser bar 1'?"l compresses the entire tube 16 against the opposite sideV of the barrel 15 the adjacent side of the tube 16 is sti etched and exerts a slight downward pull upon the presser bar 17, or

a pull in the direction of the open end of the barrel 15. This pull or pressure of the tube -16 tends to draw the upper enlarged end oftheress'er bar 17 toward the opposite side 'of t e barrell Vagainst the tube 16. This actioninsures the collapsin et the upper Aend -of the tube 16 priorl to tiie collapsing of the lower en d of the tube even when a presser barofuniform thickness, such as show n atv 1171 inI Figf, the 'enlargementl of the presser j. bar, as shown'al; 17 in Fig. 10, further invsuring the rior collapsing 'of the upper end i0 of the tube 6.. Itis thus seen that when the' in 18 carried by the presser bar ismoved' inwardly from the slot and groove.\in 'the 'sleeve 19, the -frictional contact between the tube 16'and the` presser '

bar

17 or 17 is suicient to hold the presser bar in its truc position. 'e This eculiar arrangement or form of 'the lface o the `presser 1bar provides for means whereby the-tube is complete] exliausted of air or other fluid, and wherein the fluid cannot be trapped in the .upper end of the tube. A l

The projection upon one side of the sleeve i 19 having-tile flat'sides 21 serves as a rest or means for preventing the rolling of the j pen barrel when thehpen is placed upon a smooth surfacewhich is slightly inclined. Thus the projection acts as a' stop to prevent the pen from rolling'froni desks, tables or the like'which would result in the falli e(Ping of the pen and the probable injury.
