FOUNTAIN-PEN.

Application filed July 29, 1918.

To all whom it may concern: 7 V

Be it known that I, NicKB. Dnxxrs, a subject of the Sultan of Turkey, and a resident of Ensley, in the county of Jefferson and State of Alabama, have invented cer+ tain new and useful Improvements in Fountain-Pens, of which the following is a specification.

My invention is an improvement in fountain pens, and has for its object to provide a pen of the character specified wherein the discharge of the ink from the reservoir may be nicely controlled to feed any desired amount of ink and wherein the feed may be retained constant.

In the drawings:

Figure 1 is a side elevation of the improved pen;

Fig. 2 is an end view looking at the point;

Fig. 3 is a longitudinal section of the pen holding portion;

Fig. 1 is a similar view of the reservoir holding portion;

Figs. 5, 6 and 7 are sections on the lines 5-5, 66 and 77, respectively, of Fig. 3.

Fig. 8 is a sectional detail showing the connection between the disk and reservoir.

The present embodiment of the invention comprises a pen section 1 and a reservoir section 2, one end of the pen section being reduced and externally threaded, as shown at 1, for engagement by the open end of the reservoir portion.

The reservoir, indicated at 3, is arranged within the reservoir section, and the said reservoir is shaped to fit within the said section and is provided at the end adjacent to the open end of the reservoir section with an externally threaded disk 4 which engages the internally threaded portion of the reservoir section, the disk closing the end of the reservoir. The reservoir is collapsible, being preferably formed from soft rubber of the character used in forming toy balloons.

The disk 4 has a central opening, which is normally closed by a plug 5 and this plug has extending through the same a tube 6 which feeds ink from the reservoir to the pen, to be later described. The disk 4 also has a filling opening which is normally closed by a plug 7.

The pen section 1 has a curved slot 8 for receiving the pen point 8, and the bore 9 of the pen section is internally enlarged, the enlargement extending from the end remote Specification 'of Letters Patent.

Serial No. 247.201.

from the pen point tonear the opposite end. A sleeve 10 fits within this enlarged portion, and bushings 11 and 12 are arranged witliinthe sleeve at the ends thereof, thebushing 11 forming a valve seat, while the bushing 12 is internally threaded for engagement by the threaded stem 13 of the valve 14, which cooperates with the seat.

This valve is journaled in a collar 15, and as shown, is tapered with a fine taper and the point of the valve extends within the seat. The outer end of the stem 13 has a head 15 for convenience in turning the valve, and it will be obvious that by means of the valve the flow of ink through the bushing 12 may be nicely regulated. A passage 16 leads from the interior of the sleeve 10, delivering at the pen point as shown in Fig. 1 for conducting the ink from the interior of the sleeve to the pen point. The bushing 12 closes the bore 9 of the pen section, so that the ink cannot flow out except through the passage 16.

An annular scale 17 is arranged at the end of the pen section adjacent to the point, for cooperating with the button or knob 15, to show the extent of opening of the valve.

In use, the reservoir is filled by detaching the reservoir holding section 2 from the pen section, after which the plug 7 may be removed. When the reservoir is filled this plug is replaced, and the pen section and reservoir holding section are again connected. It will be noticed that the tube 6 is of sufiicient length to extend into the bushing 11, and when the valve 1 1 is opened the ink may flow from the reservoir, through the bushing 11, into the sleeve 10, from whence it passes through the passage 16 to the pen point. Any suitable cover may be provided for protecting the pen point, the said cover engaging the adjacent end of the section 1.

A piece of rubber 18 or the'like is provided for conducting the ink from the passage 16 to the pen point. It will be understood that after the proper regulation of flow is obtained the valve is permitted to remain in adjusted position, to insure the discharge of a constant amount of ink. Ordinary pen points may be used with the improved pen, the said points being held in place by a ferrule 19, as shown.

I claim:

A fountain pen comprising a reservoir holding section and a pen point holding section detznhably connected, a reservoir held within the reservoir holding section and detachably conneeted therewith, said reservoir having at the open end of the reservoir holding sectionadisk having threaded engagement with the reservoir holding seetioinsaid disk having a filling opening and a feed opening andatube held in the feed opening, the pen point holding section having a tubular i valve seat into Which the tube extends, and a tapering or needle valve cooperating with the other end of the seat for regulating the flow thereof, said valve having threaded engagement with the pen holding section near the outer end thereof, and the said 15 section having a passage leading from the interior thereof to the pen point.
