Be it known that I, DAVID YSBEAUMEIJ, a-

citizen of the United States, .residing in Brooklyn, county of Kings, v:and `Statebf vNew York, have. linvented certain lnew and useful Improvements in Self-Filling Fountain Pens, of which the following is a specification. .i

My invention relates `to'improvements in what are lknown as selfffillling fountain pens, 1n which therefis generally employed a barrel containing a collapsible ink-holding font or' sackmade of suitable liquid-prc'iof material, such assoft rubbei, the font Vbeing collapsed by means of a presser-member engaging its side longitudinally thereof, and

rwhich member is actuated by a device accessible to the operatorl from the eXteriorof the barrel of the fountain-pen, said member being so mounted as to return to normal position whenwthe .pressure is released .and the font is diStended. -In ,filling this oonstruction of fountain pen, the` operator moves with his finger the device for actuating the presser memberwhich upon being depressed serves to collapse the .font and eX- pel therefrom r :the: contained air and any remaining ink, whereupon he dips the pen` nih into the ink'in` the ink-well so as to sub` merge the nozzle'whic'his connected with the font, and then vreleases the` pressure onthe presser-member and the inkfont `'at-oncefdistends itself, sucksin the -ink- `and thereby ltis.: the object of my present yinvention to provide` simple, Ipositively operating mechanism, `by means `of which the operator may quickly rre-illthe ink-font lwithoutliability of overthrowing the operating-lever beyond a position substantiallyl normal to the presser-member, and in which the 'lever in its sliding'conneetion with the` pressermember is so guided as to prevent lateral displacement of the parts, and also to provide a simple and durable mounting for the spring pressenmember and in. which close Contact or juxtaposition of theparts is se cured, when the parts 'lie in normal positions with the ink-font distendedl; and further to provide a simple formofbearing for the pivot-pin of the operating device. AI' also provide a novel construction ofv lever, which `can be readily made from sheet-metalthen doubled on itself to forml a-inished device without requiring any nishingoperation- There are other novel'features and arrangement" ofthe `several different partsy of `my invention, allof which are more fully herejinafterl` set 'forth and thenlpointed out in theclaims. `j i 1 y, I have'. illustrated a type of myinvention in the accompanying drawings, wherein,

In 'this viewI the'operating lever is shown .as moved vinto "a positionnormal to y the presser-bar, toycompletely vdepress it and to collapse `the font', and lin which con- .dition "the pen-nib is dipped intothe 'inkwelly yto fill the font vby closing down the lever, into `the positionshown in Figf.`

lReferring tothe drawings in which like numerals ofreferencedesignate like parts r "throughout, l isa `cylindrical barrel closed lattlue butt end and open at the other-fend `on which is mounted, the nozzle 2, `carrying the pen-nib 3, and itsfeed device.v To the inner end ofthe nozzle is secured the mouth tain itself therein by friction. At each side of the opening 8, in the support 9, is formed a bearing 11, for the corresponding end of the pivot-pin 7, the bearing being constructed by slitting the metal at 12, parallelwith the slot and bending one part 13, outwardly from the plane of the metal to form a halfbearing, and bending the other part 14;, outwardly from the plane of the metal in the opposite direction to form a half-bearing, the two halves together forming a substantial bearing for the end of the pin, as clearly indicated more particularly in Figs. 3, 4, and 6. I thus provide a simple and substantial form of bearing requiring but little work to form it by means of dies,'and without soldering.

The operating lever 6, is mounted so thatv the short arm engages the presser-bar 15,v to depress it and the engaging end of the lever is of a peculiar shape which will be hereinafter more fully described, the action between the two-said parts being like that of a cam.

The presser-bar 15, is likewise made of a resilient metal piece andis somewhat longer than the support 9, to which the bar is secured at the rear end by bending the bar hooked-shaped at 16, and nesting it. within. the bent end of the support. The end of the bar is formed with lateral ears 17, and they are bent around the end of the support 9, taking into the notches 18, formed in the edge of the support, as indicated more particularly in Fig. 5, and the two members are thereby secured firmly together in operative positions. `By virtue of this construction, the collapsing means for the ink font t, which lies between the presser-bar 15, and the interior of the wall of the barrel at the opposite point from the bar, is a dnitary ticle or device comprising the operatinglever, its support and the presser-bar, and when once assembled and inserted in the barrel, the lever snaps into the slot 5, in the barrel with a snug fit so that the parts remain permanently in place in thebarrel, the lever or actuating part, assistingin so retaining the unitary device at the saine time being accessible from th'e exterior for manipulation by the operator, the outer longitudinal edge of the lever lying flush with the periphery of the barrel and the operative or engaging end of the lever being adjacent the forward end of the slot 5, and preventing withdrawal of the device from the barrel until the'entire lever is pushed down to allow the end thereof to escape the end of the slot, leaving the device free to be withdrawn in case it is necessary to do so. This simple composite device renders it easy for the workman to put the fountain pen together, by inserting the device endwise in thc open end of the barrel before the nozzle is applied and pushing it to the rear until the bent end 10, seats itself against the end of the barrel while the operating-lever by virtue of its resilient mounting, snaps into operative position in the barrel slot 5, and locks the device in operative position. The inkfont L1, which is fastened at its outer end to the inner end of the nozzle 2, is then slid into place beneath the presser-bar 15, and with its butt end seated against the rear end of the bent bar and finally the nozzle is screwed onto the barrel as shown in the drawings. The font may then be collapsed for filling it, by lifting the long end of the lever with the finger, so that the short end of the lever en gages the back of the presser and slides along the same as it depresses the bar into itsvlowcrmost position, the lever is then reversed in its movement and the presserbar restored to normal position, likewise the lever, by reason of the resiliency of the metal support and metal bar, and also the distension of the rubber ink sack or font.

The hooked parts 10 and 16, ofthe resilient members 9 and 15, respectively, are so constructed and arranged that the ends or beaks thereof and the main part or stems of said members, spring apart when unconfincd and stand out of parallel, as shown particularly in Figs. 4 and 5, so that when the device is inserted in the barrel 1', the hooked parts and main parts are forced into parallelism and exert a'spring pressure upon the opposite walls of the barrel, and thereby retains; the device securely in place and maintains the twov members 9 and 15.nnder spring tension and pressed outwardly against the interior wall of the barrel. Both of the resilient members D and 15, being free and unobstructed from their point of connection at 17, to their outer ends, act like fixed springs, and the 'presser-bar 15, has a free and wholly unobstructed sweep in its depressing movement against the side of the ink-font, so that it serves to collapse the font to a great degree, as; indicated in Fig. 1.

1n order to keep the presser-bar and operating-lever from relative lateral displacement, l provide the bar with a guideway 19, in the form of a longitudinal groove and the engaging end of the lever slides back and forth in this groove in its operations.

The operating-lever 6, is of a peculiar shape and is made from sheet metal out of which a blank is cut with clean edges, double the width to be used, and then-is doubled on itself and pressed together as shown in Fig. 7, so as to forrn the finished article and thereby dispensing with machine or tool work. The short-arm of the lever is provided with a hole for reception of the pivot-pin 7, the hole being indicated at 20, and passes through both layers of the folded sheet-metal, being formed in the blank as it is cut from the flat. This pivot or fulcrurn hole is located in eccentric position, that is AiO is shorter than the radius--'25, the `radius increasingfrom the point`Y 24C- to 25,' thereby providing acam-like structure, so that when the 'presser-bar has been forceddown firmly against the side of the font as it vis pinched `orsqueezed between said bar and the side of the barrel which 'thusl limits the downward movement of thebar, the low part of said edge 23, may pass over the bar, the high partcannot do soy and binds thereon,

stopping the lever in a position somewhat short of normal to the bar, as indicated inl yFig;v l. Thus-the high part 25,'servesA to stop the lever fromgoing beyond vnormal positionfand hence thev lever. cannot overthrow such position, and consequently there is no liability ofthe presser-bar being depressed 4to its full limit and then raised slightly and again depressed, which action would. cause 'accidental expulsion of the ink which i'smost objectionable and would make the pen unsalabvle.` In Fig; 1, the parts are shown in their respective positions assumed when the lever. is moved into its `full open position and the presser-bar is forced down firmly 'against the collapsed font which in turn is pressedagainst the wall ofthe barrel which thus-acts as an abutment,iat the same time the upper. side ofthe support 9, bears against the side of the interior of the barrel also as an abutment. As the shortarm of the lever is so proportioned as to stop the lever in the position shown in Fig. l, such part acts like a wedge or cam between the fulcrum and presser-'bar when the latter is depressed to its full limit, and the cause thel lever to piicklyfsnap back into tendency is to reversel the movement of the lever which nevertheless remains locked by virtue of the high-part of its end wedging itself against the presser-bar, and the eX- tended contact `between the presser-bar and the sloping end 23, of the lever. LUnder this condition the endwise pressure against I the open lever keeps it firmly in open position, but a slight reverse movement of the outer end `of the leverby the operator, will closed position, the-action being like'the movement off a dead-center. Thus thereturn movement of the operating-lever is practically automatic, after an initial movement .is given it vby the operator.

lt -Will "be observed `that in case the fountain-'penis to be taken apart, this may be readily done byunscrewing the nozzle 2,

and removing therewith .the attached inki font 4, and then'byl depressing the closedk lever so that yit `will escape the end of the 1 slot' '5, in the barrel, andi removing the unitary structure ofthe metalpartsincluding the operating-lever, itssupportand` the presser-bar, so .that the unitary structure `is not only of importa-ricain assemblingthe vfountain-pen, as 4hereinabove pointed out, but j also in taking'the `same apart, n-fact'the fountain-pen thus made comprises but three f unitary parts, namely-,the slotted barrel, the

nozzlel andl attached ink-font andptheop.- erating-lever,-with its support and presserbar.

i As-the lever 6, pivoted to the supporty 9,.'the vwide partl .of thezplev'er, indicated `at 22, .extends below theunder'side of the Asupport, and `accordingly theA presser-bar `is formed with a depression26,`toreceive such` Y part of the lever andv thereby permitpvthe presser-bar to lie against the support'when the-parts are innormalpositions, asshown` in Fig. 2, yand thisvmakes the device. more compact and gves'more space for thev ink- 4font when it isfilled. The llong -arm .of .the

lever 6, is cut-away on an incline yat2, on fits under edge,r` to clear the support 9, whenl f the lever is in closed position, and its outer end is notched at 28, 'foreasy engagement' by the finger of the :operator from the eX- terior of the barrel ,which is cut-away Yat`29, to receive the endof `the lever andcause litA to `lie flush with vvthe periphery ofthe `barrelwvhen the lever is closed'.

'I wish to beunderstoodlas notlimiting `my invention to the particular construction herewith shown,` asit is'evident thatfmany 1 variations-may be `made in the several different parts of the structure, without however departing'from-thespirit of my invention. f v l j Having thusdescribed my invention, what I claim and .desirewto secure-by Letters Patent isz-,-
