roUN'rnIN-PEN.

Original No. 1,214,310, dated January 30, 1917, Serial To all zu hom 'it may concern:

Be it known that l, S'roniron'r Jossnnrn, a citizen of the United States., residing at Atlantic, in the county of Norfolr, in the have invented a newv and useful improvement in Fountain-Pens, of whichthe following is a specifica/tion.

This invention relates to that class ofV fountain pens in which an expansible'rubber sack is provided within the barrel; and mechanical means is provided in connection therewith for collapsing the same; and, more particularly, to that particular type of fountain pen in which a presser plate is arranged to engage the sack throughout suhstantially its entire length, and a lever is pivotally connected tothe pen barrel in position to press the plate against the sack, to collapse the same, so that when the sack is permitted to expand, it will be filled with the liquid in which the pen section has been dipped.

Prior to my invention, various devices of the above-described character have been pro` duced, but said devices have, so far as I am aware, been open to certain objections, some of the more important of which have been diliiculty in operation,` unreliability lof the locking means for the operating lever, un-

sightly or inconvenient projections, and exeessive cost of manufacture.

Theobjects of my invention are to provide a fountain pen, of the character above referred to, in which the lever-operating means is arranged to permit easy and convenient compression of the sack, and in which a convenient and effective means for locking said operating means is provided. Further', to provide a construction and arrangement which will enable the production of a fountain pen which has a smooth, continf nous surface throughout the length of the pen barrel, so that it will have substantially the same appearance a's an ordinary fountain pen, unprovided with mechanical means for collapsing 'the sack, and which is of simple 'and durable construction, so that it is 'unlikely to get out of order, and may be inanufacturedat a reasonable cost. I ac means shown in which" of a fountain Figure 1 is a side elevation pen embodying my invention. l

Fig. 6 is a similar' View, taken' at 'the line -ff, Fig. 2.

Fig. 7 is a plan view, showing a slightly modified form ofmy invention.

Fig. 8 is an enlarged sectional view, taken As shown in the drawing, the barrel a has the usual pen section: b mounted therein, a rubber sack c is provided, which is arranged in the barrel, and connected toa reduced portion on the inner end of the pen section.

A presser plate @Z is arrange'dto extend longitudinally of the rubber sack, throughout substantially the en,y ire length thereof, said presser plate being connected to a spring arm e, which is, in turn, connectedto a metal split collar f, the latter bein arranged to grasp a reduced portion b on the inner end of the pen section. The pen barrel a, is furtherprovided with a straight, narrow slot a', which extends longitudinally thereof from a point adjacent the middle, to

the end of the barrel, and partly across the end Wall thereof, and an operating lever g is mounted to swing in said slot a, about a pivot h, located in the barrel intermediate the lever, and in such a position that the exterior surface of the lever s flush with the surface of the pen barrel, when the .leveris in its normal or inoperative position.

The operating lever is arranged 'to provide a presser platev engaging arm` and operating arm. The operating arm is prol vided with an inwardly-extending offset portion g and is thence extended 4beyond the end ofthe barrel by a tip portion g2 preferably in central alinement with the barrel when the lever is in its normal or inoperative position. For maintaining the lever in its normal, inoperative or disengaging position with relation to the presser and all'

bar and for otherwise assisting in the manthe barrel is pro-l l :for orinmiental purposes, if d esired.

as the barrel, and forms practically a Continuation thereof or finished end to the barrel. The retention of the end piece or cap g to have engagementwith the barrel for maintaining the lever in its normal or disengaged position, is preferably obtained as `for this Jartieular mode of retention the end piece or oap might be termed a nut. To prevent lateral displacement of Athe end ,piece when in engagement with the end ot' the barrel, the end of the barrel is slightly cupped or recessed, and the ad- `jacent end ojtthe end piece is correspondingly formed to enter the same, so that the end piece may be loosened or unscrewed to an appreciable extent before the lever can be drawn outy of its normal position.

.To lill the pen, the nut'z' is unserewed to the .necessary extent, `and the lever g is swung outwardly, to cause -its short arm to force in the presser plate, and collapse the saelr, as shown in Fig. 3, so that, when the lever is swung back to its normal position, the expansive force of the sack will cause the ink to be drawn therein in the usual manner. 'The nut `z' will then be screwed agaii'ist the end of the barrel again, to lock the lever in its normal position. During the operation of the lever,\the nut i provides a convenient handle, or means for grasping it with the fingers.

Figs. 7 and 8 show a slightly modified form of my invention, in which, instead of arranging' the pivot L directly onthe hard rubber of the barrel, a metal band m is provided to receive the same, which is arranged about the' pen barrel, flush with Vthe surface thereof, said band being also made to serv lrlaving thus fully described my invention, I claim and desire to secure by Letters latent oit" the United States l; l'n combination with the barrel of a .formt `pen having a collapsible sack there` in., a piessor plate arranged to engage 'said sach, a lever pivotally mounted in said barrel and arranged to engage said plate to collapse the sack when swung from its nor mal position, and a nut threaded on the end y of said lever 'and arranged to be'screwed into locking engagement with the end of the barrel, to lock the lever in inoperative posi# tionn Q..
