Application `tiled July 17, `1909. Serial No.-508",112.

Beitknown that I, Ciiaizmis `Pizrx-ziisiza,

"My .invention `.relates to .fountain pens and 'has especial reference yto .that type in `which the pen isprovided with mechanism whereby .a fresh supply of -ink :may be dra'wrr into thereservoir, such articles being y commonly known yas self-filling pens.

.'Ifhe chief r'ibjectsv of the `ii'nprovements `wlnchform-t-he 4subject matter of this application .for atent 'are:-to provide a self filling' fountain r pen -thaty will be `simple in construction, effective in the operation `of charging the reservoir with a 'freshjsup- `ply of ink,

ingdevices will be durable, easily understood, and `convenient to operate.

I respectively, of the barrel; Figi is a fragcal section of the filling piston,

f plication, the various sprin `Furtherobjects fof the invention, referred to more :in detail, are z-to furnish a `positive lmechanism yforforcing the ink into the Areservoir by atmospheric pressure, to 4provide a `safety clip function of serving as the operating lever for the filling member, andto .produce a fountain pen having `an effective feed that will insure that the proper amount of ink is at all times supplied to the pen nib.

I accomplish the desired objects by means off the devices illustrated in the accompanyin drawing, which forms a part of 'this apdetails of construction being disclosed in the following views lFigure 1 is a sideelevation of the coniplete instrument; Fig. 2 is a vertical longitudinal section; Fig. v3 isa side elevation of the cap, with the safety clip and sprin 'removed; Fig. 4 is 'a front elevation o the safety clip; Figs. 5 and `6 are fragmentary views showing the upper and lower ends,

to the details of the drawing,

Referring c 11 indicates a cylindrical barthe numeral rel, lopen at the top and having its lower and so constructed that the lill-` having the additional The said clip is normally will expand so as thus retain the spring end 12' contracted andprovided with :a slot 13 `for the insertion of .a pen-114. -Tlieaipper lend 15 ofthe pen'is `reduced'-forming shoulders 16 4which enga'gelt'lie marginsof vthe said slot 13, thus formino' stops to properly locate `the member .relatively to the vfeeding mechanism. The 'feeding :parts comprise a beak 17 )which 'is a reducedex-y tension of the barrel walls, fandvisfurnished upon one side with `a latlface 18A whichis a jacent the slot 13 `andwis'pi'ovidediwitha groove 19. This e groove communicates'fat one end with the bore 20 of the ybari'l,-ftlie lower end terminatingfshort of the endfmargin 'of said face.18,as^shown 'inFigs Gand 7.4 The upper open end of the barrel is normally closed by a cap 21, whichtelescopes v,over tli'e ysaid open :end andvex-tends downward to-a sutiicient distance to afford a "iirm connection when tliusengaged, the cap being readil removable 7for the purpose'iof 'til ing the re A20 with ink.

fTlie upper end `22 fofwtlie cap isfsolid 'except for a slot 23 ii'- which is '-insertedthe u per end 24 of a clamping lever or safety clip A25, which normall cap `and barrel-in 'the ie ative position shown in Figs. 1 and 2. This clip or `lever coniprises aiiat metal strip which is reinforced along the median line lof the, outersurface flattened endQ/l, the latter being secured in the slot 23 by a pivot pin 27. The lower end of the clip terminates in an outwardly turned hoop 28 which lies in close 'proximity to the outer surfacey of the barrel, as 'indicated at 29, and serves vto engagethe margin of a pocket or other convenient portion of a garment for the lpurpose of preventng the instrument from becominglost, a su cient resiliency beino' provided by the'vmetal clip to facilitate this clamping function.

tion shown by means .pf a U-shaped spring 30, which is placed within the interior of the cap 21 through a slot 31. The bent mid-portion 32 of the spring is 'lodged in av hole 33 formed in `the wall, of the cap opposite to the said slot 31, said hole being countersunk upon the inside of the cap to form a suitable seat l'for the said bend. lVhen :'.i position tlie end 34 of the spring to engage beneath the shown in Fig. 2, and

in position when once inserted. The opposite end of the spring wall of the cap, as

held in the `posi-V lies alongside the a' rib 26 yand this merges above into the vProjects slightlyA and is yformed vinto a head 35 whielr protruds through the slot 31 and a slot 36in v.the clip. A" hook 37 engages the wallofthe clip adjacent kthe slot' `36` to hold the clip in place, as shown in Fig. 2,

a notch 38 .being provided for the insertion of the finger nail, lor a suitable implement, when it is desired to compress the spring to vrelease the clip.

Within the bore 21 ofthe barrel is slidably arrangeda piston/39, furnished with a suitablefpacking ring 4.0'. I prefer to form 'l -this piston f `hard rubber and make thev ring of Soft rubber to insure a proper lit andinsure an `eifective `action of the piston {wlthout producing a friction which would prevent thedevice from working smoothly.

This piston is provided with a screw-eye this purpose being as follows The piston.

`11,which is inserted into an axial hole in lsaid piston, andserves as an attachment forthe hook 'end 28 of the clip 25, by .means of which the piston is operated to fill the barrel, lthe manner of using it for stands normally near the upper end of the barreljas shown in Fig. 2, 'and -when the reservoirv becomes empty of ink, the cap 21 isfremoved, and the clip released by compressing the springv with the linger nail, which ,engages the notch 38. The hook 28 is then made to engage the screw-eye 41,

and 'to facilitate this procedure, the upper A end of the barrel is lfurnished with a mar- ,ginal slot or slit 42,'the special advantage be entirelyfilled below the piston. Disenbeingthatthe' piston can thus be reached whenit is below the upper end ofthe barrel. I-Iavingthus engaged the screw eye' with vlsaid hook, the piston is then pushed to they bottom ofthe cavity.' The lower end of the barrel is now dipped into the ink lsup y ply and' the piston-carefully drawn back -by means ofthe engaged clip to the initial position at the upper end of the barrel, the

ink being drawn by way *of the groove 19 into the `reservoir 20, so that the latter will gaging the hookfrom the screw eye, the

clip is folded," alongside the cap as before,

where it ljvv'ill bef automatically secured by 4. A fountainy pen comprising piston, a slotted cap fory the barrel, and means for operating the piston comprising -a lever pivoted f in the cap and having' an the spring. The cap `is then replaced upon the barrel, when the pen is ready f or use.
