Be it known lthat .RU'EL VVHH'NEY,` a citizen -of the,United States, vresiding at Cleveland, in the'lcounty of Cuyahoga and State of Ohio,'have 'invented certain new and useful Improvements in Feuntain-Pen Fillers; and I'do declare the following to be Iand more especially to 4an'd-theobject ofthe same is to simplify and a full, clear, and exact description'o'f the invention, such as will enable others skilled in the art to which it app'ertains to make and use the sa e. y

This invention relates to fountain pens,

improve that type of fountain pens which has an elastic inklreservoir contained within 'the barrel and means for manually com- 'pressing "it when `taken up.

a' chargeI of ink is to be ity removed. V Fig. 4 is a perspective detail of the compressor withdrawn from the barrel.

In the drawings the letter B designates the pen barrel having a closing plug P in its upper end, N is the pen point or nib, and It is-the ink reservoir connected therewith and generally 'made of rubber communicating with the nib through the collar C which screws into the lower end of the barrel. No novelty is claimed for these features of construction as they are all well'- known in the art of fountain pens.

Coming now more particularly to my present invention, the compressor `best seen in Fig. 4 includes a stiti" metal strip 5 long enough to extend substantially throughout the lengt-hof the flexible reservoir, a leaf springt secured at its upper 'end to what might be called the back of the strip 5 and having its lower end bent upward and dished a little transversely, and a U-shaped bail 7. whose bend is by preference mounted loosely in an eyc 8 across the upper end of the strip 5 and whose arms have `outturned feet-9. This bail may be of light wire, and' L Can conceive the possibilityv that it might be Specification of etters *Patent primat-i011 med'nay i, ien.' serial No. 6242x949.

two members in one the Iillers thereofg' Patenten oct. 1o., ieri.

formed as a piece ofone of the metal memlbers although I prefer to pivot it in the eye 4as shown. Said members are by preference of separate pieces secured together as by .solderingbrazing, or riveting, because one must be stili'l andthe other resilient; but l can conceive the possibility .of making these piece having two legs which possess these. attributes. In the upper end of the pen barrel B are eut two notches or grooves 10 which 'the feet of the bail engage. i

Longitudinally through the top of the barrel l form a slot 20, and acrossits upper 'end a depression` El of sucientsize to admit ythe tip ofthe finger nail. In said slot is mounted a lever 22rpivoted lc'etween its ends on a cross pm which extends across.

the slot and is secured inthe wall of the barrel, and the upper end of the lever is bent inward as at 220 so that it will be impossible for it to catch on the pocket of the wearers garment.

In assembling the parts'oil a pen made of this construction, the reservoir is inserted into the barrel while the lever lies flat, and the collar screwed into the lower end of the barrel to hold the parts in place. Next the compressor is inserted into the upper end of the barrel, the operator pressing the spring close against the strip and inserting the lower end of the latter between the to'p` of the reservoir and thelever which still lies vflat. -The grooves in thebarrel are. so disposed with lrelation to .the lever that as the compressor is fully inserted and the feet of the bail passed into said grooves, the dished end of the spring will pass beneath the inner end of the lever. Fnally the upper end ot the barrel is closed by the plug and the device is ready for use. To till this pen it is only necessary to hook the finger, nail under the upper end of the lever and raise the latter to the position shown in F ig. l; this causes its lower end to turn inward and it slides upon the spring rather than'upon the rubber reservoir, and said reservoir 'is of course compressed. Then the pen point or nib is inserted inthe ink and the lever laid down flat; this permits the rubber reservoir to open and suck in a charge .of ink. When the pen again becomes empty, it is necessary only to raise the lever, insert the pen point in ink, and drop the lever so that another charge can be sucked into the reservoir.

Thus it will he seen' that l have produced a fountain pen filler wherein the lever never ooines in Contact with the rubber reservoir and cannot tear it, and wherein the outer extremity of the lever lies within a cross notch or depression in the barrel so the linger nail can be easily insert-ed under italthough it be hooked as shown, and yet no article of clothing can get under such hooked end accidentally. Another feature is the wire bail whose bend is pivoted to the strip and whose out-turned feet lie in grooves in the' upper end of the barrel, thus permitting it to swing upon its feet as the strip rises and falls in the operation of filling the pen. Still another important feature is-the spring which is of course of less strength than the normal expansive tendency of the rubber reservoir in order to permit the latter toexpand and suck in. a charge of ink. The function of this spring is to prevent rattling of parts, accurately guide the inner end of the lever7 and hold the strip down with gentle force even after the lever has been swung back to its normal position7 so that the rubber reservoir may expand and sue-k in a charge of ink rather slowly. The partsl are oi' course of the desired sizes, proportions, and materials, and the penis suseeptible of other features of improvement without eonfiiet with this invention.

that is claimed as new is:

l. ln a fountain pen filler, the Combination with the barrel having a pair of longitudinal grooves within its upper end and a longitudinal slot through its wall, a lever pivoted in said slot, a pen point, and a normally expansible reservoir contained within the barrel and Connected with said point; of

a stift' strip between the inner end of the lever and said reservoir, an eye in the upper end of the strip, a U-shaped bail having its bend. pivoted in said eye and its 'arms provided withou't-turned feet loosely engaging said grooves, and a plug for closingvthe upper end of the barrel.

2. In a fountain pen filler, the' combination with a barrel, a pen point, and an expansible .reservoir connected with lthe latter'l andcontained within the barrel; of a lever pivoted between its ends within the wall of the barrel, a stiff strip lying upon said reservoir, a spring weaker than the expansive foreeof the vreservoir and having one end connected with the strip and the other endA dished'land .lying under the inner end .of the lever, and a flexible connection between said strip and barrel.

In testimony whereof I have hereunto set iny hand in presenceof two subscribing wit nesses.
