siding et No. 2046 Ashland avenue, in the ful lniprovexnent in Self-Filling Fmintninsection is the usuel ink channel sind feed har Pens, olI which the following is n speeilieotion.

My invention relates to self-filling i'ounj tain-pens, oi' that Glass in which :in elnstie ink-reservoir is contained m u hollow pen" holder.

One object of my invention is to provide on improved means ol' opernting the device by which the pen i; elenncul, und the reser- Voir iilled.

Another ohjeot is to g'irovide :i pen-holder oi" n Smooth and. iinisluyi appearance, in which no port of the eelllilling rneelninien'i is left protrtuling or detoehnhie.

The holder ie made in three seotions that, when united, form one continuous :uid smooth pen-holder. 'the principal section, l, is .mode hollow, to eene-iin the ink-reservoir `ond eomprefssion-lever. At one end is :t tenon, 2, adapted to engage the swivel-oop, 3, rotntnllly mounted. thereon. "he other eind is opento admit the insertion ol` the oompressor-lever, the ink-reservoir und the pen-4 seetion, L common to self-fillingi'ouutnin-pens, hnving `in its outer end the pen, 5, and on its inner end the tenori, (i, ndnpted to engage the seetion al, und. the neck, 7, adopted to engage the ink-reservoir, 8. Suid ink reservoir is nn elastic tulle, prefernhluvr oi` soit rubber, elosed j at one end und eementod :it the other upon 1 Said penrseetion is ol' the type i -to the ope/rnting-lever, l2.

eonneeting the reeervoir with the pen.

lVithin the# section l, und hetvveen the wnll thereolv` und the ink-reservoir, is n conn pression-lever thntcomprises n compressionlmr, .l, united lljv comlooting-urine, l0, to the pivots, 1], und through one oly 'the seid pivots Seid parte 9 to l2 inclusive are preieruhly mudo oi one eontinuoue pierre ol non-emrosive, tempered, wire, lient nt the several plneee und :ingles required to 'form the several parte. .'.lo provide hearings l'or the pivots l 1 l out zt groove, i3, on one side ol the tenen 6, and drill an aperture, '14, in elinement with seid groove, through the tenon 2. The eompressionlever, when i'ornied, is placed within the section l. :ind is held lirn'lly against the interior thereof, in the position it assumes when the inloreservoir is fully expninled. protruding through the hearing 14, is then inserted through un aperture, l5, in the side of the swivel-oop 3, und is lient in o direction diun'ietrieally neross the tenon 2. As the swivel-Gzip settles into its place upon the tenen the hond in. the wire, neeessuryF to forni the lever Sl, is completed; and the swivelenip is at the saune time looked, hy said lever, upon the tenon, in such u way es to prevent its removal therefrom while. not 'preventing its rotation thereon, for a suilieient are ol the circle to operate said lever, and through it the oompression-lever. The Wire is then out oil' even with the outer surl'eee o'l' the i swivel-cup.

For proteetion of the pen, and :is nn eX- tension of the holder, l provide the oop, lo, in nommen use. on l` untninpens. ln order to prevent seid rep from engaging either one ol' the 'short Heet-ions of the holder, the sume is inode slightly tapering at enel: end.

ln practical use of the device VI have found that the form und size ol the. wire oompressor-levr-u' is sueh as to give u very satisi'nrtory degree of compression to theI inku reservoir. But n, more eomplete compres.- sion ie fobtuinehle by the use of a oompressenplete, 17, of thin Inetnl, extending the entire length of the har il', and hinged thereto hy clips, 18, nt eoeh end of the har. ,l therefore desire to deserihe and'elaim the use otsueh compressin'fplnte-us nn alternate ll'orm ol' eonstrtuztimr. -Snil plate i7 is oon- 'vex, to,eoniorm to t'lie'eurve 'of the holder into which it is ressed, and it extends unthe neel( oi' the. pen-section, through which der,on'd a little ieyond, one of the'eonnect- The wire,

feg-

ing-arms to prevent any tendency the late may have to. turn over upon the lever. eing supported throughout its length by the bary 9, resting upon the concave surface thereof, said plate is made very thin, and partially encircling the bar it occupies a comparatively small space' within the holder, and does not make necessary any reduction in the size of the ink-rescr .'oir.

The construction, and arrangement, of the parts being thus made known, it is thought that the method of cleaning and lillingl the pen will be readily understood.

On turning the swivel-cap toward the right the aperture comes within a shorter radius from the bearing 14, thus causing the operating lever to protrude beyond the surface oi' the swivel-cap at all times while said lever is out of its original position, which is diametrically across the tenon. The further the cap is turned the further the operating-lever protrudes, until it is stopped by the compression-bar reachingthe further side of the interior of the holder. Thus is furnished a visual means of determiningl the position of the compression-lever within the holder. Moving the compression-bar, or plate, down upon the ink-reservoir collapses the same, expelling the air or the hquid therein contained. rIhen, with the end of the pen section inserted into the ink, a reverse turn is' given to the swivel-cap, returning all of the operating parts to their original position` 'Ihe ink-reservoir, relieved from the pressure of the lever, expands and ills with ink. Should the feed or channel become clogged, or should the ink thicken in the reservoir, the

trouble iseasily remedied by forcing water,`

4or thin ink, through the channel, by the p'rocess above described, until all obstructions are removed.

Thev friction of the swivel-cap upon the tenori-is suilicient to guard against any accidental turning of the lever.

Having lthus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a self-filling fountain pen, the combi- .nation with an elastic ink-reservoir of a'principal section ol" the penholder, a compression llever pivoted at both ends within the principal section -of the holder, an operating-lever external to the principal sectionof the holder integral 'with the compression-lever /and engaging the swivel-cap, and a swivel-cap adapted to cover and protect the operation lever and to furnish-means by which the same is operated.

2. In a Self-lilling fountain pen containing` an elastic ink-reservoir and a compression lever parallelwith the reservoir and pivoted at each end of the principal section of the. holder,y an operating-lever integral vwith the compression-lever and external to the principal-section of th'e holder; a rotatable extension of thepenholder, engaging the operatinglever, adapted to protect said lever and furnish means by vvhicnit is operated; and a 'compression-plate hinged upon the compression-lever, parallel with the same and adapted to more completely collapse the ink-reservoir.

3. In itself-filling fountain pen, the combination of a pen-section, an elastic ink-reservoir attached thereto and a pen therein with an ink-channel and feed-bar leading from the' reservoir to the pen, a hollow principal-section oi' the penholder adapted to contain the reservoir, a compression-lever extending longitudinally between the reservoir and the principal-section of the holder and pivoted at each end thereof', an operating-leverintegral with the compression-lever and external 'to the rincipal-section of the holder, and arotata le extension of the holder adapted to cover the operating-lever and to furnish Ymeans by which it is operated, having an aperture in the side thereoi` adapted to engage the operating-lever, y f

4. Ina self-filling fountain pen ofthe character described, a hollow principal-section of the pen-holder, an elastic ink-reservoir therein, a compression-lever therein pivoted at e'achend thereof, and a presser-plate hinged upon the compression-lever and adapted toy more completely collapse the elastic ink-reservoir.

5. In a self-filling fountain pen of the character described, a hollow principal-section of the pen-holder, an elastic ink-reservoir therein, journals at either end thereof adapted to engage the pivots of a eompression-.lever, and

a compression-lever therein made of a continuous pieceoic wirebent at the proper places and angles, comprising a presser-bar, an olset'at each end thereof, a pivot extending from each oiset in a line parallel with the presser-bar, and an operating lever at substantially a right angle to one of the -pivots and external tothe principal-section ,of the holder. t v

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses.
