H. A. MYERS FONTAIN PEN June 2l, 1932.

. Filed OC.. 27, 1930 V// l1 ,xEwIJnl-m Patented June 2l, 1932 UNITED f STATES HUBERT A. MYERS, F TOLEDO, OHIO FOUNTAIN PEN 1 'Epplianon alieafoctober 27, 1930. serieu N6. 491,332.

My invention relates to an efficient means for filling fountain pens` whereby the objectionable, and often obno`Xious,'covering of the finger-grip end of the shell with ink 'isI avoided, and also Vwhereby ink may be drawn and the pen'may be charged with the ink from acontain'er, when the level of the ink is very low in the container.

In the preferred form of the invention, the

0 fountain pen is provided with an elastic bag whose outer end, ythat is, the end remote from tliepen end o f the fountain pen, may be opened and, upon expansion of the bag, the pen may be illed through the said end. A suitable cap or plug or cover is provided for covering t-he outer end of the bag, whereby all exposed ink-smeared surfaces are entirely enclosed while the penis in use.

The invention consists in other features and advantages which will appear from the following description and upon examination of the drawing. Fountain pensV containing the invention may partake of different forms and may be varied in their details and still embody the invention. To illustrate a pracf tical application of the invention, I have selected a fountain pen embodying ,the invention as an example of the various pens, and details thereof,that contain the invention and shall describe lthe selected pen hereinafter, it being understood'that variations may be made and that certain features of my invention may be used to advantange without the corresponding use of the other features, without departing from the spirit of the invention. The particular penselected is shown in the accompanying drawing;

Fig. 1 illustrates al view of a longitudinal section of the fountain pen referred to. Fig. 40 2 illustrates a side view of the pen, a part of the pen being shown as broken away.

In the particular form of yfountain penl shown in the drawing, the fountain pen is provided with the Vusual shell v1', having the 4o pen point holding member 2, andthe plug 3 andl an elastic ink bag ll, or other ink con# f tainer, that is connected to the member 2 and located within theshell 1. The pen point 5 1s fitted or vsecured in' the member 2 and'is covered and enclosed by a-cap havingthe breather holes 7. krThe pen-point 5 forms a" surface of a passageway that communicates with the interior of the bag 4 throughfwhich' ink may be drawn into the bag 4 andmay be allowed to be gradually' fed to the pen point 5, in the manner well known inthe art. Y The movement ofthe ink into theibag 4, in f the filling operation, is brought about' by the usual bag depressing means, such as by means of a bar or plate 10 that, when depressed,`will force the air from within the resilient bag, and, when released, will permit the bag t to expand anddraw ink into the bag, in the manner well known in the art. The bar 10 may be depressed by a suitable means, such as the lever 11, that extends.throughv and lies l within the wall of the .shellv `and mayl be operated by the linger in the well known Infthe use of theordinary fountainy pen',` they pen point must be placed well below Y the level of the inkf in order to draw ,a ma'- p terial amount, of ink into' thebarg.' Conse- "Q quently,fit is necessary thatthe'ink, in thef,`

` container from which itis to bewithdrawn,

has considerable depth. Itis often found troublesome to maintain the ink in the supply container sufliciently'full ofink, in order to properly lill the pen. In order to 'com-V pletely fill thepen, by the elasticity of the sci bag, after it has been forcibly collapsed by the bar 10, the end ofthe shell must be inserted within the ink to'prevent the entrance of the air between the plug 3 and the pen `point 5 into the passageways ofthe plug 3 and the member 2,` and into the bag 4. This requires that the container shall have a-depth equal to the lengththat the penpoint 5 pro` trudes'from ythe member 2 and invariably results in not only ink covering'the entirey Y shown in the drawing is provided with a surface of the pen, and the plug 3, but also end of the fountain pen with ink and toV enable iilling of the pen from containers having ink at a low level, I` have'. provided;

a means for filling the pen through the end of theshell remote from the pen point and enclosing and covering theexposed parts ofi the said means with a. suitable cap. The pen nipple 15. thatmay be secured'vin the endv of the shell 1A by any suitable means. UIn order. to easily assemble thebag 4 andthe member 2 Within the shell 1, the nipple 15 is so formed. that it may be moved into. the. con-` tracted end portion 16 of the shell 1 andsecured vby a suitable elastic ring 17 that, is located-1 in a channel:18 formedin the nipple 15., This willA prevent movement of the 'nipple .15 inwardly into the shell 1. The nipple 15, hasa passageway 19 that communicates with the interior of the bag, and theouterA end oftheb'ag and nipple is closed" by means of a, cap 20 that may be threaded ontothereducedendportion 16 ofthe shell l. Preferably the bottom ofV thek cap 2O is provided with an elastic'disc 21 that willinsure sealing ofthe. end of the` nipple and.

closure ofthe end of the bagv4. The cap 20.'. may bereadily removed from the, shellA to open the bag. y

Asis vwell known, in connection with fountain pens, the passageways between the, penV point and the bag4 are frequently clogged by thickening of the ink and, consequently,

nkmay bedrawninto the bag 4 after the air is forced therefrom by the. operation of the bar 10 "through, thenipple 15. I Thenipple 15 may beinserted into acontainer. and' the open endoffthe nipplemay lne-placed, if

desired, on thevbottom.ofthecontainer and so as to remove substantially all ofthe ink from the container, provided it does notex.-

ceed the capacity of, the bag 4. Further.-V

morethe cap` 6 alsoprevents the movement of a: material amount of, air4 into the bag, since it coversthe pen.

25. The valve 25 may be a ball check valve, spring pressed by meansy of the spring- 26, located intermediate the ball-25 and the pin 27. The ball, 25 islocatedlin the recess28 which forms` a part ofthe passageway thatinter- If. desired, the pen` pointend'of the bag 4 may be closed by meansof asuitable valve.

connects the'pen point 5, and the bag 4, and is located in the pen holder member 2. The

pen holder member is provided with a seat 29 that coacts with the ball 25 to close the passageway 30 and, consequently, to close the pen point end of the bag 4. In order to open the valve 25 and enable the flow of the ink from the bag to the pen point, and also to enable closure of the pen point end of the bag 4, when it is desired to draw ink into the bag 4 through the nipple 15, a wire, or rod, 32 is located within the bag so, as to extend through the passageway' 30y of the pen point holder member 2, and the passageway 19 of the nipple 15'. The length of the wire, or rod, 32, is such that,` when the'cap20 is screwed into the end of the shell 1, and the wire 32 is forced inward so that'it's end lies Within the end of the nipple 15, the ball 25 will be raised from its seat 29, substantially as shown in Fig. 1. Preferably, the` wire, or rod,.32, is bent at portions 33 located in proximity to the inner ends of the pen holder member, 2 andy of the nipple 15. This displacesthe. central'portion ofthe wire, or rod, 32 and also prevents the wire lfrom dropping through the nipple 15 and. out ofv the passageway 30. This also enables the movement of the bar4 10 across ythe shell to the opposite side ofthe shell duringy the compression of thebag4... Thus the pen may be filled with'ink through either lend of the shell,

but, preferably, through the end remotefrom the ingergrip ofthe pen,.that is, through the nipple 15 whichmay be closed ,by the lcap 20 to cover any inlr smeared surfaces.
