This invention relates to a fountain pen of the kind in which a cartrid e of ink is contained within a barrel, and it is concerned more particularly with certain improvements by which the cartridge 'is opened concurrently with repositioning of the .pen stock upon the barrel end.
In the use of a fountain pen'of the kind in question, a residue of wasted ink will alwa s remain in each cartridge. In handling t e cartridge, particularly when. its seal is bro-" ken at the time the cartridge isjplaced in use, ones hands are apt to become soiled'an experience that is disagreeable at best. Except for difliculties, such as these, the car tridge type of n is advantageous, inasmuch as extra sup hes of ink can conveniently be kept on hand or carried around to be available for immediate use, when required.
It is with the object in view of improving fountain pens of this character, and in particular of facilitating the opening of an ink cartridge, and of effecting a better drainage of ink therefrom, that this invention is concerned. A suggestive embodiment thereof is set forth in the accompanying drawings wherein Figure 1 is a longitudinal section through the pen in its entirety; v
of Fig. 1;
Figs. 3 and 4 are enlarged fragmentary sectional views showing the pen stock in two different positions; I Fig. 5 which is a view in pers ective look ingtoward the cartridge end ows in section theblade which opens the cartridge endadjacent the pen stock;
Fi 6 which is a similar view shows the 4 cartridge end opened in 81118111181 somewhat diiferentlyfand -Fig. 7 which is a view similar to Fig. 2 shows a modified construction.
The en assembly includes the usual cylindrical. arrel A closed'at one end by a wall 10 and at the other end by a removable pen sto'ck'B, and a cap 0' adapted for frictional mounting on' either the pen stock or opposite barrel end, iniaccordance with usual v practice. The inner end of the pen stock is Flg. 2 is a transverse section on line 22 in the form of a n p le 11 exteriorly threaded for connection witii' screw-threads that are internally provided on the barrel adjacent its end. A shoulder 12 on the pen stock abuts .the barrel end when the one part is screwed to final position relative to the other.
The present pen stock furnishes a mounting for the pen point or nib 15 to which ink -isfed through a passageway 16 extending through-the pen stock to. its inner end, the passageway terminating, by preference, offcenter diametrically opposite the nib. Adjacent the openin to this passageway is a knife blade 17 carrie by the pen'stock and extending inwardly into the barrel for an appreciable distance. This blade is of peculiar formation, in that it is curved somewhat in a plane transversely of the barrel axis, and is tapered to a point at its inner end 18, which lies substantially at the-axis of the pen.. The cutting edge 19 of this blade extends from its pointed end a substantial distance toward the pen stock.
1 The walls of the barrel near its opposite or closed end are desirably extended inwardly somewhat in a non-round formation, as-suggested in Figs. 2 and 7. The cross section through the barrel at this point may be such .as to rovide a polygon-a square, hexagonal,
or 0t er form-01 a single rib 24, as indicated in Fig. 7 may be substituted therefor. Within the barrel I arrange a cartridge D in the form of a vial having its inner end formed with a cross section which is complementary to that of the non-round end of the barrel, the
purpose being to secure thecartridge against rotation therein If desired, a cushioning pad 20 may be interposed between the barrel and cartridge end, as shown. Theopposite cartridge end which lies proximate to the pen stock is sealed as by a closure or disk 21 adapted to be cut into by the blade for release of the ink supply.
In'use, the pen parts are assembled with the ink cartridge first placed within the barrel, its inner end being received within the corresponding end of the barrel where it is held against-rotation. The penstock is next applied to the open end of the barrel and ro-- tatively advanced therein through interengagemcnt of the screw threads forming the connection therefor. In this operation, the pointed end of the knife blade advances to engage with the closure at the outer end of the vial. The initial contact of the knife blade is substantially at the center of the closure, but with continued rotation of the pen stock, the blade is required to travel through a circular path, and being disposed angular-1y with respect to the axis of the pen, the continued inward travel of the pen stock will result in the blade cutting from the closure a helical ribbon, such as is suggested in the drawing. This helical ribbon may be drawn outwardly by action of the knife blade to lead the ink as it drains from the vial, or if the blade be otherwise formed than is shown in Figs. 1 and 4, the ribbon will be inwardly pressed as it is produced. In either case, the closure is ruptured to permit flow of ink from within the vial into the space adjacent the inner end of the pen stock.
It may be found desirable to interpose a coiled spring 22 between the pen stock and proximate end of the vial, as shown, to maintain the vial in a fixed position where it cannot shift around or become loose. It may also be desirable to provide adjacent the vial a gasket 23 against which the spring end exerts pressure, the purpose being to prevent escape of ink from within the space below the vials containin ink may be kept on b and for,
use whenever resh supply is needed. Such a contrivance is especially advantageous for those who require, when traveling, the use of fountain pens, and a convenient source of extra ink supply at hand. In such case a supply of vials may be carried along, and as needed they may be used in the manner described. In the handling of the vials there is no problem of esca ing ink due to rupture of the closures there or being deferred until after the en stock is started on its way to final position following its assembly with the pen barrel.
