FoUN'rAIN PEN.

4Application led Apri1 26, 1927. Serial No. 186,751. l

This invention' relates to-an improvement in fountain pens wherein provision 1s made for utilizing substantially the entire bar rel of the pen as an ink reservoir; and providing means to insure against any possible leakage of ink from the barrel when the pen is not 1n use.

The primary obj ect of the invention is the provision of a fountain pen in which the 1n- 10 terior of the barrel is uninterrupted substan-l tially throughout the full length whereby to utilize the full interior of the barrel as an inl: reservoir and thus carry a much larger quantity of ink than in other pens of the same size barrel. Y Y

A. further object of the invention is the provision of means, designed for manual operation, by which the flow of ink to the pen point may be cut off at will, thereby Sealing the barrel against possible leakage at this oint. p A further object is the provision of a cap which is slidably mounted with respect to the barrel and otherwise inseparable from the barrel, the cap having means by which one end maybe closed when the cap is projected into cap-forming position vor opened to permit the projection of the pen point therethrough when the pen is designed to be used so for writing purposes. v The invention is illustrated in panying drawings, in which: v, Figure 1 is an enlarged longitudinal sectional view, partly in elevation, showing the improved fountain pen.

Figure 2 is an enlarged end viewl of the ca igure 3 is yaview in elevation of the pen,

the accomshowing the cap in dotted outline vin osition to cover and conceal the penpoint an in full lines in position to permit ordinary' Writing use of the pen. l

Figure 4 is a broken section of the barrel and-ca the valve for sealing this end of the barrel 4[Dyeing shownin closed position.f

The improved pen comprises a barrel 1 which, of course, is of conventional form exteriorly and may be of anyappropriate size commensurate with the type'of pen contemplated. At one, that is the upper, end of the cap-like `form, the joint connection 3 between the barrel and closing section being such as to permit the 'removal of the closing section when necessary, thoughz ordinarily servlng Vto connect these barrel there is provided a closing section `2 of parts `,to prevent their casual separation. l

The top or end wall fl of the closing section is formed with an inwardly extending annular wall 5, which opens through the top of the closing section and is open at the bottom. This wall 5 defines a space inwardly of and annularly divided from the wall of the barrel. i

The lower end of the wall 5 is providedA with a central bearing sleeve 1l to slidably receive the stem 12 of a valve disk 13, which latter i's of a size .to completely close the `enn4 trance to, that is the lower end of, the space within the wall 5. B suction applied to the upper end of the pen t e reservoiris filled.

The opposite or lower end ofthe barrel is provided with the usual fixed plug 18 having a central passage 19 for the ink. A closure 20 is threaded into the barrel below the plug 18, this closure being formed or provided on its upper side with a valve plug22 adapted, when the closure isin its upper position, `t o close the lower end of the channel 19 and prevent the passage of ink therethrough. The `cloa knurled flange 23, the diameter of which is substantially equal to the exterior diameter ofthe barrel, said closure having a reduced extension 24 to removably receive the pen plug 25 with which cooperates the pen point 26.

- sure 20 is provided on its-lower surface with- The closure 20 is hollow and its upper wall l is formed with openings 27 beyond the valve plug 22, the pen plug 25 having the usual channel 28 to permit the flow'of ink to the pen point. Thus, when the closure 20 has been moved t0 a pointto open .the channel 19, ink will readily reach the pen point for/ordinary writing purposes. In this position of the closure, as indicated in Figure 1, it will be noted that the flow of ink to the pen point is, following its flow through the channel 19, accumulated in the hollow closure as in a minor reservoir.l y

The improved -pen isl designed to be pro- Videdwith a cap which,-wl1en in closing positlonf-acts to protect the pen point and at the Sametime preventv the clothing from being soiled by the ink accumulated on the pen point when writing. AThe improved cap, however, iszdesigned to form a more -or less permanent part ofthe barrel and to have a sliding cooperation with the barrel, bein otherwise inseparable rom the barrel. T e cap, therefore, includes a sleevelike member 29 of an I the pen is eompletelyprotec'ted both against interior diameterto snugly embrace. and fit the exterior of the barrel 1, the wall of the cap having a projection 30 sliding ,in a' groove 31 in the barrel to permit sliding movement of the cap relative to the barrel `Whi le preventing separation of the parts. f

The outer end of the barrel is provided,-

ting the shutters to be opened and closed by rota'tion of the section 32 as well understood. The cap 29 is further provided with diametrically opposed openings 34 which, when the cap is in extended or closing position, are aligned with the knurled flange 23 of the closure 20, whereby the closure may be manipulated in itsthreade'd connection with the barrel to open or close the channel 19. The pen, of course, may have the usual retaining means 35 arranged at any convenient point and adjacent either end of the pen though preferably as shown arranged adjacent the upper end. v

In filling'the barrel with ink, the lower or writing end of the pin -is first arranged in writing relation, that is, the closure 20 is moved to open the channel 19 and the cap 29 thereupon moved upwardly onto the barrel,

the shutter 33 having been opened to permit the end of the cap to pass over and beyond the pen point. Ink'is drawn into the barrel of the pen by suction applied at the upper end through any convenient valve..

Following the filling ofthe pen, if the pen is not desiredfor immediate use, the cap 29 is moved to its Aextended or closing position,

as indicated in Figure 4, the closure 20.is

turned by means of the knurled flange 23,

now accessible throughthe openings 34 in the cap, and the valve plug 22 moved to seal the lower end of the opening 19. The shutter carrier 32 is then operated to close the shutter and both ends of the pen are completely sealed against ink leakage and the pen point end of liability to injury and against possibility of soiling the clothing with which this end of the pen may come in contact.

When the pen is to be used for writing, the closure 20 is turned to open the channel 19, the shutter operated to open position and the cap moved rearwardly to expose the pen point, as indicated in Figure 1, following which the pen may be used in the usual manner.

It is, of Course, to be understood that the closure 20 may be adjusted relative to the plug 18 to' any extent desired to thereby regulate the flow of ink through the passage 19 as may be desired for the particular use of the pen or in accordance with the character of the writing fluid.

' lVhat I claim to be new is 1. A fountain pen having a barrel, a cap slidably mounted on one end of the barrel, the closing end of the cap being adapted to be opened at will, and a sealing closure for the lower end of the barrel operatively accessible through the cap when the latter is in one position.

2. In a fountain pen, a barrel, a cap slidably mounted on one end of the barrel, a' closure to seal such end of the barrel, said cap being formed with openings to permit operative access to the closure when the cap is in capforming position., and a shutter closure for the end of the cap to permit such end to be opened.

3. In a` fountain pen, a barrel, a cap slidably mounted on one end of the barrel, a closure to seal such end of the barrel, said cap being formed with openings to permit operative access to the closure when the cap is in cap-forming position, a shutter closure for the end of the cap to permit such end to be opened. and a pen point plug and pen point carried by the closure and adapted to project through the opened end of the cap when the latter is moved to an inoperative position on the barrel.

In testimony whereof I affix my signature.
