in tie county oi M .gaand State oie. New "li orti, have invented certain new and useiul oi/"enfrente in eountairpPene, et which llowing is a epeeriioation.

This intention reiates to fountain pens,

more particularly to the irnovvn ae self- '.lhe prineipai obieet ot' this invention is to provide a eelilling fountain en which is oi? durable eonetruetion and is e .eient and eert-ain in ite o eration.

ln earrying outiny invention, 'l provide an. automatic valve Whi. is freely movable longitudinally oi axis to close communibetvveen the inlr duet and the lower enel of the barrel A. tube entends from this Yve to the upper portion of the barrel to eonouet the air which is forced out when the valve is automatically positioned to interrupt 'the communication as before stated. This valve is certain in its action and is totally'iree from any joints or other connections which may be liable to get out of rder.

Ail"urtlier objects and advantages Will appear from the deseription and the claims.

' lin the drawing Figure l is a longitudinal section, through one forni of iny improved construction in which a flexible sack is used for the purpose of expelling the air.` Fig. 2 is a longitudinal section or another` form of my improved construction wherein a solid plunger ie used for the purpose of' expelling the air and being provided with means :for shutting ofi' all communication between the barrel and ink duet *when the pen ie not in use; the valve also being :formed with a tapered he d. Figs. 3 and i are sectional l f i" erent forme oi' valves 'L Shaving fi formed i er .,m, The interior i oi" l r diameter than. the

this valve is formed substantially spherlcal, so as to snugly t theY edge of the shoulder 5 when pressed against the same in any position Within the range of its movement and also to allow the ink to flow freely past the valve when, the latter is out of engagement with its seat. The edge of the valve is made sharp so as to avoid sticking to the barrel. A tube Z is eonneeted'to the valve 6 preferably centrally thereof y and extends through the saine and back to the upper part of the barrel. This tube establishes oominnliioatlon.y between the ink duet and the upper end of the barrel when the valve is forced against its seat. The upper end of the vtube is provided with a'eollar 70 having a sharp edge 71. This eollar acts as a Weight to keep the valve tilted in the position shown in Fig. 1, when the pen is in Writing position. The sharp edge prevents the collar from sticking to the barrel. The upper eno. of the barrel is open vand has clamped thereto, a sack 8 of flexible, elastic material such as soft rubber. `This sack is clamped to the barrel by means of a sleeve 9 extending referably in the interior of the barrel. cap 9a may be secured over the top of the barrel, seas to normally inolose the rubber sack..

TWhen it 'is desired to ll the barrel, the pen is dipped into the ink and kept preferably vertical, with the level of the ink extending up to the tapering finger portion of the barrel. The rubber sack is then alternately eoinpressedand allowed'to expand. When it is eo compressed the air is forced out through the tube'and the pressure thereof also seats thae valve 6 against the edge of tlie bore 2, thus preventing the egress of ink` past the shoulder into the bore and feed duet. When the sack is allowed to eupand, thelvalve is forced upward away from' its seat and ink flows up through the feed duct to replacethe air which has been expelled. Several Vmovements of this sort of the flexible' sack are sullioient to lill the pen. When it is desired for :my reason to expel the ink from the pen or to clean by expelling Water whi/fli has been previously drawn into the r this purpose, the sack may be Worked same manner as before indieated, but

' the shoulder 16 is engaged by the spherical with thepen kept atan angle to the horizonl' tal with the end of the finger portion out of the liquid. When the pen is kept in this position, the valve is prevented from seating and inasmuch as no liquid can be drawn in,

*a compression of the sack will serve to expel .any liqhuiid which may remain -in the barrel.

n t form illustrated 1n F1g. 2, I substitute plunger 10 in place ofthe rubber sack. T is plunger is contacted by packingv communi ink duct, this plun'ger is moved inward to the limit o its travel, and in this position, it

contacts t e end of the tube 7 causing it to,

seat again the edge of the bore 2 and also closing the upper end of the tube. The end of the plun er is dished, forming a concave, spherical s face which is adapted to properlycontact with the convex enlargement 7 of the tube 7, in substantially any position.

' The valve (ia in this form is shown as tapered insteadof spherical.

In the form illustrated in Fig. 3, a.y form of valve is shown having a fiat surface 6b.

adapted tocontact with a sharp edge 5 about the bore 2. This sharp edge maybe formed by forming an annular depression on the shoulder between the barrel and the bore.

In the form of valve illustrated in Fig. 4,

valve 17. This shoulder-'is of substantially sphericalconcave form and is thus readily engaged by the spherical valve 17 "It will be noted that in all of the forms f shown, the valve is freely movable with rel spect'to its seat and the construction is free e from joints-,or other derangeable connections of any'kmd. The pen can be very quickly 'and easilyh lled or emptied .and may be easily adjusted so as toclose all communication between the interior of the barrel and the ink duct. If desired, all-flexible material may be omittedin the construction "as illustrated in Fig. 2. "lhesg features are all of practical importance 'i' af fountain pen of this type. y y

Having thus described niy invention, l claim- 1. A fountain pen lcomprising a barrel, a

.bore at one end thereof, a feed plug in said bore, there being v'a shoulder between said bore and barrel forming a valve seat, a lonfgitudinally freelyA movable cheek valve engaging said seat, a tube extending from said f valve to the further end of the barrel, and

4--me'ans for forcing the air from said barrel out through said tube. f A fountain pen comprising'a barrel, a

bore at one end thereof, a feed plug in said .ther end of the barrel, and means for foreing the air from said barrel out through said tube.

3. A fountain pen having a bore at one end thereof, a feed plug in said bore having an ink duct, a freely longitudinal movable check valve for automatically closing communication between said bore and the adjacent end of the barrel, said valve having a tapering surface, a valve seat having a sharpl edge which said tapering surface engages, and means for forcing air out from said barrel through said duct.

4. A fountain pen having a bore at one end thereof, a feed plug in said bore, a freely longitudinally movable check valve for automatically closing communication between said bore and the adjacent end of the barrel, a tube extending from said bore to the upper end of the barrel, and means for forcing air from said barrel through said tube.

5.
