FOUNTAIN PEN.

APPLICATION FILED umso, 1907.

ERNEST EARLE MORLAN, OF GARDEN CITY, MISSOURI.

FOUNTAIN-FEM Specification of Letters Patent.

Application ld August 30, 1907. Serial No. 390,719.

To all lwhom t may concern:

Be it known that I, ERNEST E. MORLAN, a citizen of the AUnited States, residing at Garden City, in the county of' Cass and State of Missouri, have invented certain new and useful Improvements in Fountain- Pens, of which the following is a specification.

My invention relates to improvements in fountain-pens, and one`of my Qbjects'is to provide two simple means whereby the main 'reservoir may be quickly filled without removing any of the interior part-s of the fountain-pen.

A further object is to provide means for controlling the liow of'ink to the pen-point to avoid blotting.

. AA further object is to provide means for sublnergingthe pen-point so that it will be ready for use without shaking the fountainpen to start kthe ink to fiowing.

Another object is to' provide a feeding arrangement that will not. require fineadjustment of the pen-point;

Other features of the invention will hereinaf'ter appear, and in order that it may be fully understood, reference will now be made to the accompanying drawing, in which: y

Figure -1 represents a vertical sectional view of my improved fountain-pen, the parts being in position for carrying the same in the pocket. Fig. 2 is a vertical section of Ithe fountain-pen with the parts arranged for filling the reservoir with ink, Fig. 3 is an enlarged broken section of the lowerportion of the fountain-pen. Fig. 4 is an enarged cross section von line IV-IV of 4i0'. 1. i i

iadesignatest main reservoir consisting of a barrel 2, partly closed at its ends by plugs 3 and 4, which latter is conical at its lower portion and provided with an auxiliary reservoir 5, communicating with the main reservoir through a port 6. Plug 4, which 'is hereinafter termed therpen-holding plug, has a pair of grooves 7 for the reception of a pen 8, the-insertion of which is limited by its upper end contacting with a shoulder `9. vThis arrangement permits a common pen to be employed as the'fine adjustment between the pen and the feed-mechanism required in a number of fountain-pens now on the market is unnecessary.'

The flow of ink from the main reservoir to the auxiliary reservoir and pen 8 is controlled by a valve 10 provided with a stem 11, the upper portion of which .extends through a central opening 3 in plug 3, while itslower conical portion 12 extends downwardly and terminates a 'short distance above `the lower end of pen 8.

13 designates-a washer interposed between valve 10 and the upper end of the pen-holdlng plug, which latter has a concave recess 14, in which the washer is seated by valve' 10 when it is desired to close communication between the reservoirs. Plug 3 is provided with packing 15 and a nut 16k surrounding the upper portion of stem 11 to prevent the lnk from flowing through opening 3a when Patented Jan. 4, 1910.

the fountain-pen is inverted. Nut 16 and stem 11, so that the valve may be adjusted to open or close port 6 by Vraising or lowering the cap.

18 designates a sheath which performs` the double function of protecting the pen-point when not in use, and forming means whereby reservoir 1 may be filled with-ink. Said sheath is open at one end so that it may be slipped upon either end of barrel 2, and is provided with a mouthpiece 19 having threads 2() whereby an internally threaded screw-cap 21 may be secured thereon for closing the mouthpiece, so that the same' will hold ink when in the position'shown in Fig. 1. To prevent ink flowing from the mouthpiece to the exterior of the pen-holding plug 4 while being carried in the pocket, I hold the lower end` 18a of the sheath tightly against the lower end of said plug. This is accomplished by providing the open end ofv the sheath with internal screw threads 18c which engage external threads on the upper end of barrel 2.

vReservoirl may be filled with ink by removing the pen-holding 'plug and pouring the ink directly into the reservoir, in which instance the mouth of the bottle containing the ink is placed in contact with the projecting conical portion 12 of the valve-stem, so that the ink will follow the same into the main reservoir. The main reservoir may also be filled by first loosening nut 16 and*- packing 15 so that air may pass upward through opening 3a, sheath 18 is then screwed upon the upper end of the reservoir, as shown in Fig. 2, and cap 21 is removed so that the mouth may be applied to mouthpiece 19 for the purpose of exhausting the air from the reservoir to draw the ink therein.

While the penis being used to write with, the valve is left in a raised position, see Fig. 2, where it is held by frictional contact with the packing 15. As the writing proceeds the ink will'low down the narrow channel 22, between-the conical portion 12 of the valvestem, the wall of reservoir 5, land the pen 8 because-capillary attraction is greater at this point than in reservoir 5, which latter is provided principally to receive the excessive flow from the main reservoir as hereinafter described. As the ink flows from the main reservoir its place will be taken by air entering therein through port 6.

Should the air in the main reservoir expand from becoming warm and force an excessive quantity of ink therefrom, the excess ink will not flow immediately to the penpoint and blot the paper, but will enter the auxiliary reservoir 5 and be directed, as needed, by the reduced lower sloping portion thereof to the pen-point and channel 22.

When the fountain-penis not in use, sheath 18 with cap 21 thereon is adj usted to the position shown in Fig. 1, to protect the pen-point, which latter extends downward into the mouthpiece 19 and is constantly submerged in ink which flows into said mouthpiece from the auxiliary reservoir by way of pen 8. By thus submerging the pen-point the fountain-pen will be ready for use Without shaking the saine to start the ink from the main reservoir.

Having thus described my invention, what I claim is 1. A fountain-pen consisting of a main reservoir, a stationary pen, an auxiliary reservoir communicating with the main reservoir through a port of less diameter than either of the reservoirs said auxiliary reservoir having a lower reduced portion sloping toward the pen-point which is inserted therein, and movable means for controlling the flow of ink from the main reservoir to the auxiliary reservoir, provided with a stem which in conjunction with the pen and the adjacent inner surface of the auxiliary reservoir form a channel' for the purpose described.

2. A fountailrpen consisting of a main reservoir, a channel leading therefrom, a pen communicating with said channel, a sheath adapted to slip. upon either end of the reservoir, provided with a mouth-piece through which air may be exhausted from said reservoir when the sheath is applied to its upper end, and to receive the pen-point when said sheath is slipped over the lower end of the reservoir, and a cap for closing the mouthpiece when the sheath is in the lastmention ed position.

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

ERNEST EARLE MORLAN.
