FOUNTAIN-PEN.

To all whom it may concern:

Be it known that I, JAMES W. CARLIN, a citizen of the United States, residing at Sandusky, in the county of Erie and State of Ohio, have invented certain new and useful Improvements in Fountain-Pens, of which the following is a specification.

This invention relates to fountain pens, and has for its object to provide a fountain pen equipped with a valve which may be adjusted to vary the flow of ink to the pen point, and which will be so arranged as to cooperate with the cap of the pen, to hold the valve shut when the cap is in position, so that the pen may be placed in the pocket in any manner, without spilling the ink.

Another object is to provide a pen having a valve of this character, which will be so arranged that the parts will be easy of access when replacement or repairs are necessary.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts of the several views,Figure 1 is a longitudinal seetion through the valve portion of the pen, the valve being shown open. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is a section through the pen with the cap in position, showing the end of the finger piece engaged in the cap slot, and the finger of the cap engaged in the pen slot. Fig. 4 is a fragmentary section, showing the cap partially on the pen.

Referring now to the drawings, there is shown a pen including a reservoir handle 5, which is interiorly threaded at its open end as shown at 6. Acore? is threaded into this open end of the handle, and this core is provided with a head 8, which corresponds in size with the reservoir handle, and which abuts against the outer end of the handle. The head-8 has in its outer face a recess. 9, which is provided with an interior left hand thread, and screwed into this recess there is the reduced rearward end 10 of the forward end portion or feeder 11 of the pen, having a groove 12 for the reception of a pen nib 13, and having a feed finger 14,

which receives ink through a longitudinal passage 15 formed in the portion 11, and communicating with a passage 15 formed longitudinally through the core 7, this passage 15 opening through a beveled valve seat 16 formed in the rearward face of the core, this valve seat surrounding a washer recess 17, which in turn surrounds the rearward end of a central longitudinal passage 18 formed through the core. This passage 18 communicates with and is disposed concentric to a recess 19 which is formed in the .rearward face of the reduced rearward extension 10 of the portion 11, and a radial slot 20 communicates with this recess 19 and opens through the outer face of the portion 11, as shown.

A cylindrical valve 21 has a bevel 22 which fits against a valve seat 16, and this valve .21 has the groove 23 in its outer periphery which may be brought into and out of registration with the passage 15. In this way the aperture of communication of this passage 15 with the ink reservoir may be varied or may be closed entirely as desired.

A rubber washer 24 is disposed in the recess 17 and the valve 21 carries a longitudinal stem 25 which is engaged through the central passage 18, and which projects into the recess 19, where it has screwed thereupon a head 26, which bears against a second rubber washer 27 engaged between this head and the outer surface of the core 7, which surrounds the passage 18, the two rubber washers efiectually preventing the leakage of ink through the passage 18, as will be understood.

The head 26 has a passage 28 formed radially therein and threaded, and this passage receives the end of a threaded rod 29, extending through the radial passage 20, and having an outwardly extending end which forms a finger piece 30. This threaded rod bears against the threaded end of the stem 25 and thus prevents disengagement of the head 26 from the stem.

By engagement of the finger piece 30, the valve may be shifted to vary the flow of ink through the registering passages 15 and 15, as will be understood.

A longitudinal slot 31 is formed in the pen and receives a finger 32 carried interiorly by the cap 33, this cap also having an interior cap slot 34, which receives the finger piece 30, as will be understood. The relative position of these elements is such that, when the finger 32 is in the slot 31, and the finger piece 30 is in the slot 34, the valve is in closed position, so that leakage of the pen while it is in the pocket is prevented.

What is claimed is:

1. In a fountain pen, the combination with a reservoir, a feeder connected with the reservoir, a pen nib connected with the feeder and means for feeding ink to the nib, of rotary means for varying the flow of ink to the feeder and for at times stopping the flow of the ink, and a cap for the pen, means on said cap for engagement with the ink varying means when said means are in position to cut off the supply of ink and means on the cap for engagement with the pen nib, both of said cap means being so arrangedthat the cap may be placed on the pen only when said varying means are closed.

2. A fountain pen comprising a reservoir, a core engaged in the reservoir, said core .to vary the flow of ink through the passage,

a stem carried by the valve, and extending through the core, a radial finger piece connected with the stem and extending outwardly of the feeder for swinging movement to shift the valve, a cap, and, pen nib engaging and finger engaging means on said cap, said valve engaging means being so arranged with relation to the pen nib engaging means that said cap is prevented from application to the pen except when said valve is closed.

In testimony whereof I afiix my signature, in presence of two witnesses.
