Thecadmember 32 hasasealing member 4i8 of' rubber' or likesuitable mate; rial which sealsgthe end of the filler member 35 when the sack IBis not being filled and the pen is in use.

In the filling of my novel fountain pen, the cap member 32 is removed from the end of the barrel I, the button I5 is moved by the finger causing the pin I3 .to move out of frictional engagement With the roughened portion 6 of the sleeve 4 and ber 39 in the cap 92.

the head 1 is rotated almost one revolution until stop portion i9 on the head 1 engages the stop member on the sleeve 4. When the head 1 turns, the sack i3 is twisted and all of the air therein isV expelled. rEhe head 1 is then rotated in a, reverse direction as far as it can be moved with reference to the stop members 5 and I9 while the filler end 35 is dipped in ink. The untwisting of the sack 19 will permit the ink to move therein andlill the sack i8. When the sack is lled, the cap member 32 is threadedly engaged to the threaded end 39 of the barrel I and the iller member 35 is sealed by the sealing memfountain pen, the head 1 is rotated slightly to increase the pressure on the ink in the sack thereby forcing it outwardly to the feedingbar 29 and the nibs 23 of the pen 2 I and through the aperture 25 in the flexible cup-shaped member 24. It has been found that with a slight twist of the head 1,.twenty sheets of paper may be written with Vmy novel fountain pen before further rotationof the head is required. The pen is always ready for use and no ink dries or coagulates and thereby stops up the end of thepen 2l. A spring clip 95 secures the portions 1 and d against relative longitudinal movement.

In Fig. 6 I show another form of my novel pen similar to the pen shown in Figs. 1 and 2 except that a ball member is provided to permit self feeding of the pen. In this construction only the ystructure of the head differs from that shown in Figs. land 2, barrel I, sleeve 2, and cap 32 being the same. In Fig. 6, head 59 has a bore 5l and a laterally extending aperture 52 in the bottom side of. the head 56. Thefeeder bar 53 has 'a tapered apertured portion 55 for receiving a ball member 56. A conventional type pen 51v and cover member 58 similar to those in Fig. 1 are disposed in the head 50. All other parts of head 59 are the same as those shown in the head 1 of Figs. 1 and 2. The general operation of my pen shown in Fig. 6 is the same as the pen shown in Figs. 1 and 2 except that the ball member 56 normally sealingly engages the laterally extending aperture 52 when the pen 51 is in a writing position and it is held downwardly. Whenit is desired to permit air to enter the feeding bar 53, the pen 2i is held upwardly and the ball member 56 will move out of sealing engagement with the laterally extending aperture 52 in the head 59 and air will enter therein. f

' Fig. 7 shows the barrel 16 .having a threaded In the operation of the 1 portion 1I for engagement with the threaded portion 12 of intermediate portion 13. Nose portion 14 is secured against relative longitudinal movement by an annular ring 15 cemented to Vprojection 16 thereof. The ring 15 engages a shoulder 11 of intermediate portion 13.

It will be evident from the foregoing description that I have provided a novel fountain pen which always keeps the pen point free of coagulated and dry ink, which is always ready for operation and use, which kpermits the ink to flow freely, and which does not permit leakage and escape of ink due to changes of'altitude or any other change of pressure or fory any other reason.

Various changes may be made in the specific embodiment of my invention without departing from the spirit thereof or from the scope of the appended claims.

What I claim is 1. A fountain pen comprising a barrel, a threaded sleeve for engaging said barrel, a bored tapered rotational member engaging said sleeve and rotatable relative thereto, a feeding bar in said rotational member, a pen having tapered nibs extending outwardly from Vsaid rotational member, an elastic flexible member sealingly engaging the end of said rotational member and the nibs of said pen, the ink feeding through said nibs of said pen to the point thereof When said point of said pen is pressed upon a writing surface, a sack connected at one end with said feeding bar and rotatable with said rotational member, a filler member on the opposite end of said sack, and means for sealing said llller member.

2. A fountain pen comprising a barrel, a rotatable bored head connected to said barrel, stop means for limiting the rotation of said head relative to said barrel, a pen having tapered nibs extending outwardly from said rotatable head, exible elastic sealing means for the end of said barrel sealingly engaging a point laterally of the nibs of said pen and the end of said head, said ink flowing throughthe nibs of said pen to the point thereof past said sealing member when the point of said pen is pressed against a writing surface, a sack rotatable with said rotatable member and secured at one end to the opposite end Yof said barrel, a llling member secured to the other end of said sack, a cap for the end of said barrel, and a sealing member in said cap for sealing the end of said filling member.

3. A fountain penV as set forth in claim 2 wherein engageable frictional members are disposed on said barrel and said rotatable member to frictionally secure said rotatable memberY at any predetermined rotational position.
