The object of the inventionisto provide several improvements in writing instrumenta-and particularly in that `class quite generally referred to as fountain-pens.

Another object is to -provide ay positive Y means for filling the reservoir ofthe foun- Vtain-pen with va liquid, which liquid though comprising water in the present instance may be the usual liquidiirik or other types of fountain-pens to which this feature of the invention may be applied, .said filling means makingit possible with'l a most direct manual operation to expel a maximum'quan- Y types ofl fountain-pens, but which isi parti'cularl'y adaptable for use in the one here-v inafter described, saidV feed comprising an ingeniously designedl channelthrough which air is permitted to flow with a` maximum-k de-l gree of freedom past the pen-point and into the reservoir, in order that anuninterrupted flow of wateigor liquid ink, as the case may be,-can flow steadily from the reservoir,- past the inflowing air, and to the'pen-point, as the operationl of writing'with the pen proceeds. c f Still anotherobject is to provide' broadly for the manufacture of liquid ink in a fountain-pen adjacent to or in the-immediate neighborhood of the penpoint,the reservoir of the pen in such case being V'supplied with water, while entirely outside ofthe reservoir and in fact close to the pen-point or nib there is positioned a 4soluble ink pellet, past and inV contact with which the water from the reservoir flows and there makes the ink, which is discharged by and from the pen-point, said pelletbeing so mounted that when dissolved a renewinglpellet may be most easily inserted inits stead.Y

, Again, another object-is to provide iIi-sueh 1.a pen a' feed member, which when in nor`- mal writing positionA hasbay transversely extending aperture, ar'ecessY inthe underside of said member spaced away from" said aperture, and a dual yholder normally containing ink-making pellets, one-portion o'fl said-hold'- er extendinginto 'and positioning a reserve pellet in vsaid recess, and another` portion of posed to water as it flows from the reservoir past the feed member to the pen, the

kwater uponcontacting with said pellet dis 'said holder extending `into and positioning an active pellet 1n said aperture and ei;-l

`Referring tothe drawings, the bodyportioni ofthe:V fountain-pen comprises any annular wall l surrounding a reservoir sectioni 2,

which-.i's-,closedat one end, and at the other end l? is externally threaded' to reeeivel the correspondingly threaded portionv' of an angular cap 6, when the pen is" not in use,

and Fig. 9 is'a plan viewof the feed the walls'V of said-capfbeingprovided with Y air passage-ways 7 .and the k.interior of said cap terminating .in one direction in the transversely extending :wall 8 beyond which l is a magazine 9'adapted to hold a plurality of soluble ink pellets 10.. f Y Y That portion of the Walls of the cap 6 surrounding the outer portion of the magazine 9 is radially reduced at 11 andV externally threaded to receive the correspondingly internally threaded portion 12 of ay ferrule, which at its free end is provided with a relatively shallow annular flange 13 surrounding an axially vpositioned aperture, While against said flange and extending through said aperture is positioned ay stone 14r for-med of suitablev material such as einery, carb'orunduin', quarry stone, pumice, and the like, which` is adaptable for 'erasing ink marks from th'e'usual rtype of Writing paper, and` with respect to the paper and the usual types of yielding rubber erasers Vis Substantially 'non-Wearing and( permanent. Tlierstone itself `is providedV with an'inner vflangeportion 15, which is firmly securedin voperative position between the flange 1'8Yof the ferrule andv the free reduced end por tion 11of the Walls6 of the cap. 'v Y That end of the V'reservoirportion opposite tothe closure 3 has secured'init in any suitable manner a 'member1'6 provided axial'- ly With a bore or throat1`17,`the inner end portion of the Walls of said member being Yradially reduced at 18 andl surrounded by the opened end portion 19'ofa sl'enderl'ccllapsible bag or pouch 2O',vsaid end port/ion beingjmaintained' `in Water; and air-tight positionfby means of a' suitablel band 21. The outerend portion 22 of the member 16 is 'formed in 4any suitable'manner eXteriorly and is provided with an enlargedaXial bore A23 connected with'the 'bore 17 byl means of anannular plane shoulder 24'for'a purpose hereinafterdescribed. f

"',fEXtei/iding longitudinally along` lthe outer surface of`v theV bag 20 and upon 'one side thereof is a yrelatively inflexible plate 25, to the centralportion of which is secured a lug 26;*ivhile the opposite end'of said lug ispro# vided with an axial bore,"'and internally ,threaded at 27 to reeeive'the similailyibut externally threaded reduced end portion 28 of an operating member-29, which extends through an aperture' 30I inH the 'Wall' 1 of said reservoir section, and4 'is provided with faV smic-iently enlarged' head v31 fr'engage ment by the nails of ones' thumb 'andffirs't linger, theouter surface of said Wall being notchedia'tso' that the iinger-nails'may be readily' 'positioned lbeneath* the head 3l', *as Willrbelevidentby reference'to'liligI if5.v

V`The central `portion oftheoppositesides of thel "bagf20 are "apertured "at and through said 'apertures "exten'd'a" pair of interlocking rivets 34, themselves*having a centrali' aperture 35' throughf'which the lug 26 'is adapted "tojpa'ss elidably Whenjthe head o lfis drawn outivardly manually, and' upon being releasedfl is ag'ain 'draxvn inwardly vby virtue of the resiliencyof the Walls of said bag`v` v -Normally positioned 4Within the enlarged bore 23 of the member 16 is a so-called feed-V iember illustrated in Figs. 2, 4, 5, 8 and 9. This feed member comprises a body portion 36, which is provided with a normally vertically extending' saw-cut 37 in order to provide a lpassage through lwhich air may pass vertically, as hereinafter described, in enter# 'ing the throatr 17 andV bag 20, to relieve the vacuum ,and permit fluid 'to'flow' from ysaid Ibag through'thethr'oat and'to axpenpoint or nib38, the shank 39 ofWhich penpoint 'embracescthe upper lside ofthe outeriother- Wise open side ofparestricted channel eX- tension 40 offthl saw-'cut 37,v and at its innermost lend said pen-pointjabutting againsttl'ie shoulderl 24 in the'memloer16;Y

The cutting -ofV the Yfeed member provides .a `bifurcated. inner' end portion, vthe opposite YWalls Vof which 'are relatively"v yielding. Wlhen the fountain-pen as anassembled'unit i3 in' its normal position 'foroperating, land the' feed member-'is inthe'position shown in Figs. and 4, the lotver free end portion of the' channel"V 40 'is vgradually tapered at'41, so vrthat therer is ibut'arrestricted 'opening of lthe channel against the undersurface of the pen' in 'the' neighborhood lof its point. -*2The inner Wall ofthe channel 40 is also provided Witha central saw-cut k42 inorder to permit air to floyv .upwardly'iinto said channel, 'and the underportion of said feed memberisfprovided With an aperture 43, which' extends upwardly to a channel 40 and througlrto the' upper surface of 'the feed member, and is normallyclosed at its upper 'end' by the peirpoint'itself.l 'rlfheffeed inember is also provided in'its undersurfaceivith l ai recessI 44,v colaxial with but spaced from the aperture43, andnot extending upwardly sufficiently far to lconnect'with'the channele:

' Referring'io Figs.' V4,6 and 7, there will be found apair Lofcups' having cylindrical sides 45,y and closed at 'their inner" ends by means of walls 46,".said'sides being' provided with saavcuts47, i'vhich ywhen a pellet 10 ris di sblved'y belogufr 'the'upper ertent of a cup in 'the' aperture'43, the' capillary attraction of rthe/inl(forthe sides ofthe cut or slit, serves' 'to fii'npel'lzlie' liquid"through and Aout of said aperture 43,i'nto the 'channelfell and thence i tions 48lof"`aeonnecting member Ll-Qfare 's'eform "a'unit "which when respectively filled with pellets 10 are insertable in the respective aperture 43an`drecess 44, as 'shown' in "Fig". llilhe'nthe pellet in-th'ecup Within jthe aperture '43 `is' dissolved, the pelletconshown in Fig. 4 and with the feed member in return in their respective operative positions shown in Fig. 2, the cap 6, however, being removed by unscrewing the threaded i portion 5 lfrom the threads 4, and thereafter placing the cap upon the opposite closed end portion of the body portionof the device.

The head 31 is then manually withdrawny as far as possible until substantiallyY the total length of the bag is compressed against the upper portion 0f the wall 1 (as viewed in Fig. 2), after which the lower portion 22 of the member 16 is immersed preferably in water or any other suit-able solvent for the ink-pellets, the head 31 then being released and the resiliency of the walls of the bag 20 withdrawing the -stud 26 and operating member 29 into their innermost positions as shown in Figs. l2 and 3, while in so doing the bag 20 has automatically filled itself with the solvent.

The pen is then Withdrawn from beneath the .surface of the solvent and is thereafter ready for use in the -manner intended, namely, as a. writing instrument,` for as the pen-point 38 is brought into contact with writing material and is either manually or otherwise drawn across said material, the solvent by capillary attraction is drawn solely from the reservoir 20 through the throat 17, saw-cut 37, channel 4() and past the soluble ink-pellet 1() in the aperture 43,

and thence to the pen-point,where it is discharged upon the writing material in accordance with the manipulations of the pen in writing or otherwise.

lIn practise, it has been found that it requires approximately two fillings ofl the reserv-oir with the desired solvent, in order to dissolve completely the pellet that is operatively positioned in said aperture. Vvfhen this is done, however, the pellet-containing unit is Vreversed in position as hereinbefore described and a second pellet is brought into position from the recess 44 in the aperture 48, and the pen is again ready foruse, and will continue to be as long as any of the solvent remains in the reservoir and its throat and a portion of the soluble ink pellets remains in the aperture 43.` Obviously, when both pellets have been dissolvechnew pellets may be removed from the magazine 9 -and placed in said holder for further use of the en. f p It is to be understood that the improved filling mechanism for the reservoir 2O in its broadest sense may be comprised within a fountain-peu not'. providedy with' soluble inkpelle'ts but which'depends .upoir-liquidV ink beingdrawn directly intofthe reservoir in vdistinction from the' present instance iin which only water:v enters thel reservoir,A and theuinlfis manufactured! in the immediate -Vicinity'ofthe point'of discharge' from' the pen-p-oint and as the ink is used.

Furthermore, the feed member hereinbefore described has4 been so'designed as to permit a steady inward flow of and outward flow of fluid so as to provide a positive supply of inl: for the pen and thus eliminating the usual interruptions due to fluid from the reservoir failing to flow by reason of the fact that air is unable to pass inwardly through the feed member and into the reservoir.

Still again, the maga-zine construction and' improved eraser-stone above described is adapted for use with many types of writing instruments and not alone with that hereinl described.

Having thus described my invention, what I claim and desire to protect by Letters Patent of the United States is 1. A fountain-pen, having a chamber provided with an opening, a collapsible bag connected at its open end to the walls of said chamber and communicating with said open'- ing, a substantially rigid member lying along yand extending substantially the entire length of the outside surface of said bag',`

and means extending through a wall of the barrelV of the pen and through saidbag and connected with said memberupon the opposite side of said bag, whereby substantially the entire length of said bag can be collapsed and the air expelled through said opening, 1

and then substantially the entire bag-full of liquid sucked by `and into the expanding bag through said opening, by but a single operation.

2. A fountain-pen, having a chamber pro vided with an opening, ya collapsible bag con-` nected at its open end to the walls of said chamber and communicating with said opening, a substantially rigid member lying along 'and extending substantially theV entire y length ofthe outside surface of said bag, a hollow rivet extending transverselythrough the walls of said bag, and means connected with said member through said hollow rivet and extending also through a wall of saidV chamber, whereby movement of said means v Y Y in onedirection collapses said bag to expel air and movement in the other direction permits said bag to expand and suck a liquid ,thereinto through said opening.

3. A fountain-pen, having awchaniber prom vided with an opening, a collapsible and automatically expansible bag connected at its open end to the walls of said chamber and communicating with said opening, a substantially `rigid ymember lying along and extending,` substantially' the entire length of the outsidev surface f o said bag, 'a' lhollow 1 from, and then releasing sadgmeans permits rivet extending transversely: through the the resiliency of said expansible bag to suck Walls of'said-hag, and means connected with a 4liquid thereinto through said opening and 10 l'said lmeniloer through said hollow rivet and return said means vto its vinnermost position. extending also through a Wall of-Tsaid In testimony Wh'ereofl lhave affixed my' chamber, whereby pullingl said means outsignature.
