FOUNTAIN-PEN.

' Specification of Letters Patent.

Patented J an. 28,1913.

Application filed June 10, 1912. Serial No. 702,795.

To all whom, 1' i may concern Be it known that I, Clans W. citizen of the U nitcd States, and a. r of Brooklyn, in the State of New York, have invented a, new and usclul lmprm'ement. in Fountain-l.ens, of which the following is a specification.

My invention relates to what are styled self-filling fountain pens, and more particu larly to that kind of such pens in which an inwardly movable presser, extending lengthwise of the collapsible ink bag, and interposed l'letwecn it and the tubular handle-in which the ink bag is housed, can be reached and operated by hand tl'irougl'i an opening in the side of the handle.

The invention consists in attaching the presser for this purpose to a tubula r cylindrical carrier which snugly tits and rotatable within the handle, and is provided with a lateral opening through which the presscr is exposed, and with a head which protrudes through and beyond the rear end of the handle and serves as a means by which the carrier can be rotated either to bring the opening in it into register with the opening in the side of the handle. when it is desired to make use of the prey er, or to bring the imper'lt'orate portion of the carrier opposite to, and in a position to close, the opening in the side of the handle when the presser is not in use.

ztLXittl. section, partly in elevation,

rubber ink bag is uncompressed In the accompanying drawings, to which l shall now refer for a better umlerstanding ot the .inventiond igure 1 is a longitudinal ot' a t me tain pen embodying the ii'ivention, with the parts in the position they occupy when the and the lattcral opening in the handle is closed. Fig. 9 is a View similar to big. '1, representing the parts in the position they occupy when the side openings in the handle and rotatable presser-carrier are 'in register and the rubber ink bag is compressed. Fig. i") is a View of the, presser and its carrier dctachial.

A is the tubular handle open at both ends, with the usual nozzle l), which holds the feed bar and pen, fitted into its front end. \Vithin the handle is the collapsible ink bag made of vulcanized soft rubber, having its mouth titled tightly upon the rear end ot' nozzle it. Thus far there is nothing new in the pen.

Fitting snugly within the handle A is the tion to which it may be turned.

carrier tube l), united with the handle by an anni'dar tongue and groove joint or, or other suitable joint, which, will permit the tube to rotate independently of the handle. The head. l) of the tube is closed and protrudes through and beyond the rear end of the handle, in a position where it can be conveniently manipulated to rotate the carrier tnbc-which latter fits the handle so closely that it will be held by friction in any posi- Vt'ithin the carrier tube'is suitably secured the presser E,

preferably made of spring sheet metal. It is in the shape of a long, slim, thin finger which is secured at its rear to the carrier, and thence extends forward through and beyond the front end thereof, lengthwise of the ink bag. and between it and the interiorwall of the handle, in such position that when pressed inwardly it will flatten and compress the ink bag. The carrier tube encircles the ink bag for a portion of its length as shown. in the side of the handle is formed an opening a, and in the side of the carrier is formed a corresponding opening (l in a position to expose a portion of the length of the presser within.

by rotatimr the carrier so as to bring its opening (I into register with the opening a in the handle, the prcsser can be reached by the hand and 'n'essi'al inwardly so as to coinpress the ink bag as indicated in Fig. 2. The moment pressure is released, the prcsser will more outwardly away from the-ink bag. 'hen the presser is not in use, the carrier can be rotated so as to throw the openings (1, (I out nl re; ;i;--.ti.-r, thus closing the opening in the handle as seen in Fig.1.

The cap I in this instance made integral with the carrier, can be formed in any other suitable way. The presser E, which may also be secured to the carrier in any convenient way, in this instance, and with a. view to enhancing its resilient action, has its rear portion bent on itself in U shape, the short leg of the U being attached to the carrier as indicated in Figs. l and 2. The" opening 1/ in the carrier may be houndcd'on all sides by the tubular body oi the carrier, or the olid portion of the 'arrier in adranceol' it'cau be removed, as indicated by dotted lines at (1', Fig. 3, all that is needed being that there shall be such an opening in the carrier tube as shall properly expose the pressei'.

The manner of using the attaelnnent for filling purposes is obvious, and requires no explanation.

The device is e'l'lieient, simple, inexpensive to make, and. easily and readily applied to EXlSllnlLtjfPQS 0ft fountain pens.

Having described my invention, and the best Way now known to nieof'earrying the same into practical elleet, I. state in conclusion that I do not.- restriet myself narrowly to the structural details hereinhefore shown and forth, SlIlCO'lllllilll OStly the same can be varied in some respects without departure from the invention: But

ha I claim herein as new and desire to secure by Letters Patent is:

A self-filling fountain pen comprising in combination a tubular handle formed With a side opening; a nozzle in thefront end of the handle and a collapsible ink bag Within the handle attached to the nozzle; a carrier tube fitting Within said handle and swiveled therein to rotate axially independently of the handle, ha vine a lateral opening, and a head uhieh extends beyond the rearend of the handle in position lo be nmnipulalfed to rotate the carrier; a 'nresser secured at its rear to the carrier and extending; therein in the line of the side opening in the carrier toward the front end oil. the handle, between the ink bag and the inner "\V2lll of the ha mile; the carrier being rotatable either to bring the side openings in. it and in. the handle into register so as to expose the resser, or to bring the iimierliorate portion of the carrier opposite to, and in a position to close, the side opening in the handle, substantially as and for the purposes hereinbelore set forth.

In testimony whereof l aliix my signature in presence of two Witnesses.
