Application filed May 26,

'To allcckom it may concern.

Be itknown that ,1, JO N C. WAHI a citizen of-theUnitedStates, and aresident of the city ofChioago, county of Cook, and .State of Illinois, have invented certainnew and useful Improvements in Fountain Pens,

of. which thefollowing is a specification.

,My invention relates, to an. improved lever for fountain pens and has special reference to the method of mounting the improved I lever within the pen barrel.

' An object of my invention is the novel and simple manner in which the lever is detachably aiiined -to the outer casing. of

" a fountain pen.

Otherobjects will appear hereinafter.

The invention consistsin the combinations and 'arrange nents of parts hereinafter described and claiined and willbe best understood by reference to the acompanying drawings forming a part of this specification, and in ,which,

Fig. l is afragmentary view ofa fountain pen'harrel showing a lever in closed position,

.1? 2 is a longitudinal sectional view on theflineQ-Q of 1,

Fig-3 is abottom plan view of the lever,

Fig.4 is a fragmentary longtudinal view of the pen barrel showing "the inturned flanges in the slot,

11. .5 is: across sectional view on the line 5-5 of..Fig. 4: showinga lever.in serte din the slot preparatory to vbeingattached to ,the

barrel. i

,Figs. 6, 7 and S are cross sectionalyiews of Fig. l illustrating the successive stages necessary to mount the lever in it-s proper position, and l i Fig.9 is across sectional viewpf Fig. l .with thelever atlixedthereto.

'lieferringgto the drawings, 1 indicates a relatively thin metal barrel hayingalongitudinal slot 2 stamped therein. In stamping the slot ,the edges at the ,forward end thereof. are so inturned as to .fogrrn flanges 3 and 4, whosefriirction willhereinaifter be described. i

A lever 5. is provided having Wings 6 at its outermostextremity and outwardly exv tending lugs 7 at its innermost extremity, the innermost extremity being that portion of the lever that extends through the slot in the barrel, and co-acts with the presser bar to depres E nk sack m unted ire ly slot in the barrel.

illustrated in Fig. 7. brought back to'a vert cal pos t on, and in so doing, the other end of the pin will be .respondingzto the aforementioned apertures arepunched in thefianges 3 ands. A pin 10 vis fixedly mounted in the lever, its ends extending through the apertures inthes de walls. thereof, said ends being adapted .to co-operate with the apertures inthe flanges 3 and 4 for fulcruming the. lever in the The method for assembling is as follows The lever is entered in the slot 2 of the casing or barrel 1 by being positioned at in the slot. Theinsertion of the 'leveriin the slot in thismanner isinade necessary by the fact that the lengthof the .pin '10, located in the aperturesS in. the side ofthe lever 5, is of a greater lengththan the width.

the casing as is illustrated in Fig. 5. It

will be seen that the pin-1O liesimmediately below the. flanges 33 and tin the casing 2. The w dthofthe slot in theeasing or barrel 1 is atrifiegreater than the ,width ofthc lever. To introduce the ends of the pin into the apertures in the flanges 3 and lthe slight space l)ctween the sides of ,the lever and the sides of the slot permits the lever to be tilted laterally, causing one end the p n to beraised upwardly and prcssed againstthe outwardly inclined lower end of .one of the flanges, anddue to the resiliency of the metal from which the flange is made,

.it will flex outwardly until .the .end ofithe pin reaches the aperture therein, whereupon the pin engages the aperture, and the; tlange will spring back to its normal positign as is The lever is then pulled upwardly against the flange, which flange will be fle rled outwardly from its normal position until it has reached the plane of theother end of thepin when the pin will engage the aperture in theflange as is shown intFigu 9. When both ends of the pin 10 are engaged in theaperturesin the flanges, the lever is ready for use. The extreme end of the flanges .3 and 4 are out right angles to its normal positioningw-ithturned as shown in the drawings to more easily facilitate the entry of the ends of the pin between flanges 3 and 4 in the process oflodging the ends of pin 10 in the apertures 9 in the flanges.

hen the two flanges are sprung back to their original position, the pin is locked therein and the lever cannot become detached from the fountain pen.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modificationsas come within the scope of the appendedclaims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a fountain pen in combination, a casing provided with a slot therein, resilient perforated lug members thereon, depending from the marginal edge thereof and fashioned with out-turned portions at their low ends, a lever, a pin, fixed transversely of the lever with its ends projecting laterally there from, whereby relative seating of the lever pin in the perforations in the resilient lug members directly into the barrel of the pen may be accomplished by force applied through the pin to flex the lug members until seating position is attained.

2. In a fountain pen, in combination, a casing provided with a longitudinal slot therein, resilient perforated lug members disposed at the forward end of the slot and depending within the pen casing and being a part thereof, a lever provided with a transverse pin fixed thereto and projecting therefrom adapted to be entered between the lug members against the resiliency of the lugs for seating within the perforations.

In a fountain pen, in COHlblHEItlOl'l, a casing provided with a slot therein, perforated lug members depending from the marginal edges of the slot and being a part thereof and relatively diver-gently spaced to provide clearance way at their lower ends to facilitate entry of pivoting members of a lever, a lever, provided with. laterally projecting pivot members, including a relative length dimensioning with respect to the spacing of the lug members to facilitate entry of said pivot members between the lug members against the resilient tension of the latter to pivotal seating position therein.

4. In a fountain pen, a casing provided with a slot extending longitudinally there in, a pair of perforated oppositely spaced resilient lugs formed on the marginal edges of said slot to extend into said casing, a lever having laterally extending pivot mem bers adapted to be'rotatably seated in the perforations of said lugs, the resiliency of said lugs permitting said pivot members to be forced into seating position in said perforations.

5. In a fountain pen, a casing provided with a longitudinal slot therein, a pair of inwardly extending perforated resilient lugs formed on the marginal edges of said slot and positioned opposite each other with their perforations in alinement, said lugs being spaced apart to receive a lever therebetween, a lever adapted to extend through said slot, a bearing extending outwardly from each side of said lever and adapted to be rotatab'ly seated in said perforations, the inner side of the free edge of said lugs being beveled to permit said bearings to be successively forced into bearing position in said perforations against the resiliency of said lugs.

6. The method of assembling a filling lever in the casing of a fountain pen, which consists in forming a slot in the casing and resilient perforated lugs on the marginal edges of the slot, providing a lever with opposite laterally extending bearings, passing the bearings portion of the lever through the slot into the interior of the casing, tilting the lever sidewise to cause one bearing to bend the adjacent lug outwardly against its resiliency until the bearing and perforation in the lug come into registry and the pin relatively snaps into the perforation, and then moving the lever in the opposite direction until the other lugs snaps over the other bearing.

7. The method of assembling a lever in a fountain pen casing which consists in providing in said casing a slot with marginal resilient perforated lugs, then providinga lever with laterally projecting bearings,

tilting said lever first in one direction and then back to force said bearings into the perforations respectively against the resiliency of the lugs.

8. The method of assembling a lever having laterally extending hearings, in a fountain pen casing having a slot provided with inwardly extending perforated resilient marginal lugs, which consists in passing the lever into the slot, and then forcing the bearings past the marginal edge portion of the lugs against the resiliency of the latter until the bearings and perforated lugs respectively snap into seating position.

In witness whereof, I have hereunto subscribed my name.

passing said lever through said slot and then JOHN G. WAHL.
