To all whom it may concern.'

l ,Be it 'known that l, HUGO Sinin, a subject of--rthe v)Emperor of Austria-Hungary, and

re ding at No. 31 Neubaugasse, in Vienna, Austria-Hungary, have invented cer-` tain lnew and useful Improvements in Fountain-Pens, ofy which the following is a specification 11;r 1 i This invention relates to self-filling fountain pens and particularly to pens of the type in which the ink is forced from the' link chamber by gradually moving outwardly, or away from the pen point, a sleeve or tubular member, and'in which the ink is drawn into said chamber by pushing said ysleeve inwardly, or toward the pen point. AIn pens Vof this typeas previously proposed, the

sleeve was moved relatively toan ink tube of considerably less diameter, and in all 'enm cept the extreme inner position of the sleeve,

lcorresponding tothe entirely filled condition of the pen,the user thereofv had to hold the pen by means ofthe thin ink tube, which rendered the handling of the `pen very difficult and inconvenient..

The object of the present invention is to provide an improved pen of this type, in

which the pen at the point at which it is held is of about the usual thickness and .is al# ways of the same thickness, whether vthe `sleeve or tubular member is in its inner or withdrawn positions, whereby the pen can be handled with' ease and convenience.

lVith this objectA in view, the invention consists in the combination and arrangement of .parts hereinafter more fully de scribed and clearly pointed outin the appended claims. Y

The accompanying drawings illustrate two forms of construction according to the invention, shownv in longitudinal section.

Figure 1 is one formA of construction in the pushed in position. Fig. 2 shows the same form of construction in ay partially pulled out position. Fig. 3 illustrates the second form of construction. 'In Figsl 1 and 2, the piece 2 situated in the hollow'holder 1 extends inwardly to sup,n

portV the'ink tube 3, -to 4which latter is vconnected atubular part 2 which is itself situ-rv ated'loosely inthe piece Q. The tube part 2 is" open toward the ink tube 31 and also towardithenib 13. The-ink tube 3 carries aclosing member '1l at its upper closed end-, whichfmember fits tightly within a sleeve adapted to' befpushed into andswithdrawn i Specification of Letters Patent.

from the hollow casing l. The lower end of the interior of the tube 3 by means of the small opening 7. In order to facilitate the manipulation of that end of the Vsleeve 5 which projects outward beyond the casing'l, it is provided with a knob 8 and lalso with an air-hole 9.' llhe members fl and 6 may also be arranged farther from the end of the sleeve 5 or the tube 3.

The operation of the fountain pen holder isas follows: Assuming-'that the sleeve 5 is inthe position illustrated in Fig;` 2,V that is in a partially or entirely drawn Aout position, if the sleeve 5 is pushed into the casing l Fig. l) after the nib has been dipped into the ink, then a vacuum will be created in the sleeve 5 between the members 4 and 6, and also within the tube 8 by means of the communicating opening 7, whereby the ink' will be drawn in'. rPhe ink is allowed to flow to the nib rby slightly pulling the sleeve 5 out of the casing. l, whereby the space bey the sleeve 5 is closed by a preferably integral tween the members 4 and (i is reduced in size and the ink is forced out. lt will obviously be of advantage to make the tube 3 comparativelyy thin, in order to make the annular space between said tube and the sleeve 5, as

large as possible. l

rlhe cap l0 serves as usual for protecting the nib, when the fountain pen is out of.

use and, as shown in Figs. l and 2 wher,

Vthe fountain pen is being used, it serves to lengthen it. When the above described fountain pen is quitefull, its length is shortest, although the sleeve is movable with the obj ect of feeding the nib with ink, and it is therefore very easily put away in the pocket, without the creased length owing tothe ink having been wholly or partly used, a leakage of the ink,

when carrying thepen holder in the pocket, is notv possible, because the unintentional pushing ,together of the parts, which vis pos'i sible when the pen holder lies in the pocket,

canvonly cause the ink to be drawn in.- lt would therefore be advisable, if the sleeve is:

in any drawn out position, .to push saine quite in, in every casebeforeputtingthe pen.`

when making the pen holder ready for use,

lto force the air out to thereby permit the the ink tube 3 `and the holder 1. Atthei'head 8, a sleeve 12 may be secured, which surrounds the 'holder 1 andi in'fsome cases, illustrated, is guided thereon. The remaining details of construction are the same as that of the form of construction hereinbefore described, and the method of operation is also the same. If the member 6 is pushed in, in the direction of the arrowl I, a vacuum is caused in the intermediate space between the holder 1 and the tube 3 between the members 4 and 6, and the interior of the tube 3 by means of the communicating opening 7 whereby the writing liquid is drawn in. The feeding of the writing liquid to the nib is performed by slightly pulling the head 8 outin the direction of the arrowII, whereby said space is reduced in size and therefore the liquid is driven thrugh the tube 3 to the nib. The sleeve 12, thejise of which may b e `dispensed withpsenves for covering the outer projecting part of the piston rod 11, also for maintaining av uniform thickness of holder at all points and for protecting the piston rod from bending; t-hev latter is the case especially when the sleeve 12 is guided 011 the holder 1.

, It will be readily seen that in both forms yillustrated the pen is of substantiallyv the same diameter throughout its length, and alsoy that the pen at the point at which it is held is always of the same thickness, no matter whether the member 6 is in its inner or enter positions. These are distinctly advantageous features -which distinguish the present pen from those ofl the same type previously proposed. f

Having now described my invention what I claim as new and desire to secure by Letters Patent is i 1. A fountain pen, comprising in combination, a tubular member, a pen' carried at one end'thereof, an ink tube also carried by said member and forming therewith an annular chamber, a closure member at the outer end of said ink tube serving to 'close the outer Aend of said chamber, a second movable closure member closely fitting the exterior of' said ink tube and the interior of said tubular member and serving to close the inner end of said chamber, said ink tube havlng an orifice 'communicating with said aperture adjacent said end and comun chamber and means foi' :flowing the second closure member relatively to the tubular member and ink tube, for the purpose described. Lf

2. A fountain pen, comprising in combi nation, a pair of tubular'members, one fitu ting within the other, a closure member carried by the inner tubular member, a second closure member arranged within the inn ner tubular member and connected with thel' outer tubular'member, said closure members and the innerl tubular membery forming between them an ink chamber, a pen carried by one of said tubular members, and an ink tube also carried by said member, opening at one end adjacentysaid pen and communieating through an orifice with said cham ber, said tubular members being relatively movable for the purpose described.

3. A fountain pen, comprising in combi 1i tube also'carried by said member, 'said tube opening at one end adjacent. said pen and being closed at the other end, but haru ing with said ink ehamben'said tube through both of said'closing membl tubular members being relatively m: for the purpose described.

4. A fountain pen comprising in cumbinat-ion, a holder, a pen at one end thereof, a casing within the holder-and projcrifting beyond one end thereof, a closing member integral with the casing,a closing member extending across and tightly fitting the casing, both vmembers being normally spaced apart to form a closed ink chamber, a stationary ink tube within and in communication with the ink chamber by means of an orifice, the tube being secured to kthe closing member which fits within the casing and passing tightly through the integral-'closing member and 'having its end adjacent the pen in the: holder, and a knob on the end of the casing which projects from the holder,

whereby ithe integral closing member and sleeve are moved relatively to the ink tube and the other closing member to lvary the capacity of the ink chamber for the purpose described. f

5I A fountain pen comprising in combination, a casing, apen at one end thereof, a closing member-'integral with the casing, a closing member extending across and tightly iitting the casing, both members being normally spaced apart to form a closed ink chamber, a stationary ink tube within and in communication with the ink cham vary the capacity of'the ink chamber forber by means of an orifice, the tube being the purpose described. secured to the integral closing member, and In testimony whereof I have signed my passing tightly through the closing memname to this specication in the presence of 5 lber Wlichts Withln the casing and having two subscribing Witnesses v its en a 'aeent t e en in the Casin a sleeve surrbunding thEe) casing, and mlns e n HUGO STEIN' on the sleeve for moving it and the tightly' Witnesses t, fitting closing member relatively to the'ink KARL REHAK,
