riginal No. 1,249,501, dated December 11, 1.917,. Serial No. 106,163, led June 27,1916. Application for reissue 1ed March 28, 1918. Serial No. 225,358.

To all whom it may concern.'

Be it known that I, FELIX RIESENBERG, a citizfn of the United States, residing in the city, county, and State of New York, have invented certain new and useful Imi provements in- Self-Filling Fountain-Pens,

of which the following is a full specification'.

My invention relates to fountain peil fillers of the type which comprises an elastic ink sack adapted to substantially fill the barrel of the pen, and means for compressing the sack to expel the air prepara- Vals tory to inserting the nib end of the pen into an ink reservoir. According to my invenion, as in most fillers of this type, the pressing means comprise a presser bar lying within the pen filled and adapted to be ressed against the sack by means which ie exposed in the Wall of the pen.

InV ens of this classit is necessary to provi e against accidental movements of thesack compressing parts as otherwise ink may be inogportunely exgelled. Many de- 'viceshave een suggeste for locking the operating parts in rest osition but so far as I know the devices w ich are applicable Y to the type of pen herein described either employ springs or auxiliar locking devices re uirin separate manipu ation.

e o ject of my invention is to'provide. -improved means for locking the operating parts in rest position without the employ-v ment of springs, the locking being effected simultaneously with the return of the op erating parts to rest position.

An illustrative embodiment of my invention is shown in the accompanying drawinsl in which 'gore 1 is a longitudinal sectional view of a fountain pen equipped with a filler according to my invention, the parts being shown in rest position. i

Fig. 2 is a' longitudinal sectionalv view of the central portion of the en on an enlai-ged scale, also showing' t e 'operating parte in rest position Fig. 3 is a view similar to Fig. 2 showing the operating parts in sack emptying position. Fig. 4 is av transverse sectional view on the line IV-IV of Fig. 2.

Fig, 5 is a detail view.

tively a pen barrel, nib and'feed bar of usual construction and assembled in the ordinar manner. Anink sack 4 of rubber or ot er suitable elastic material is connected at its open end in the usual manner with the feed bar 3 and forms a re irvoir for ink which is su plied as required to-the nib 2. A presser gar 15 lies against the sack 4, the length and cross section of the bar being designed to e'ect, as nearly as possible, a com lete evacuation of the air in the sack wlien the bar is pressed against it in the manner hereafter described. A lever 6, which may be called a transmission lever, is pivotally connected at Sto the barrel 1 and lies in the longitudinal slot 5 of said barrel. At its lower end transmission lever 6 is connected with the presser bar 15 b means of pin 17, carried by transmission ever 6, and slotted ange 16 carried by presser bar 15.l Operating lever 7 is pivotally connected to the barrel 1 at 9 and ike transmission lever 6 l-ies within slot 5. The outer end 12 is' under-cut and lies within the transverse groove or depression 13. The inner end of lever 7 lies upon transmission lever 6 intermediate the ends ing application, filed November 29, 1915,

Ser. 170.64055. i

Intermediate its ends the transmission lever 6 has adjacent its outer edge a recess 14 adapted to receive the inner end of operating lever 7. It will be noted'that recess 14 is for the mosty part open, but has at one end an overhanging lip 14. At its opposite -end Vrecess 14 terminates in an abutment 14.".v

The inner end of operating lever 7, is rounded and so dimensioned as to fit snugly in the recess 14 when the parts are in rest position (Figs. 1 and 2). On its under side the operating. lever 7 has an oblique notch 10 inclined toward its outer end 12. On the inner surface of barrel 1 an annular groove is formed which is adapted to receive and lhold split ring 11. As shown in Fig. 5, the ends of split ring 11 are slightly separated wey to permit it to be compressed sulii'ciently to be inserted in the barrel 1.

The unctionso the parts and operation vof the device are as follows: In rest position (Figs. 1 and 2) ,lever 7 is held Within the slot 5 by reason of the engagement of notch l0 with ring 11. Transmission lever 6 is held against inward displacement by reason of the engagement of lip 148L with the end of lever 7. It will thus be seen that no movement of the operating parts can take place .except at the `vvillvotf t ie operator when it is desired to fill the pen with ink, and that vthe ink sack, when full, is wholly relieved from the weight of the operating parts. The illing operation is performed by inserting a finger nail under the end 120i the lever 7 and raising it from slot 5. As the lever 7 approaches perpendicularityrits inner end slides within recess 14 and depi'esses transmission lever 6 thus through 1 resser bar 15 compressing the ink sack 4. `pin and slot connection between presser bar 15 and transl mission lever 6 permits a slight alternative displacement of these parts and thus avoids longitudinal displacement of the presser bar. Operating lever 7 is held in perpendicular position b abutment 14b coactin with the acute ang e between levers 7 an 6. With the parts in this position the peli nib is .in serted in a reservoir of ink and the lever 7 is then snapped back into rest position permitting the sack 4 to expand under its owii elastic influence and thus to draw in a charge of ink and at the same time to-return presser bar and transmission lever 6 to rest posiv tion. The positions of the notch 10 and ring 11 with respect-to eachother are such that as lever 7 is returned to rest position, ring 11 -Will be slightly displaced to the left and will then spring back into `place within the notch 10.

I do no t consider that my invention is lim*l itcd to the precise` form of interengaging means shown here, nor, of course, tothe particular snap-lock described. My invention in its broadest aspect embraces many :obvious variations of the interlocking elements and the means forlocking togetherr levers 6 and 7 as they return t'o rest position.y

in combination With any suitable device tending to hold lever 6 within the slot.

I claim:
