Patented Mar. 15, 1932 JAMES A. G.1 oMnnoY, on FRESNO; CALIFORNIA FOUNTAIN rENf Application led September 16, 1930. Serial No. 482,325.

The present invention relates to improvements in fountain pens, and its principal object is to provide a fountain pen very simple in character and arranged in such a manner that the means for producing suction for filling the fountain pen are arranged inthe cap instead of being in the barrel as in the conventional fountain pen. A further object of the invention is to provide a fountain pen in which no sack is needed in the barrel for holding the ink.

A further object of the invention is to provide a fountain pen with a cap adapted to fit either end of the pen and to arrange the suction producing means in the cap in such a manner as not to interfere with the application of the cap to either end.

A further object of the invention is t0 provide, in combination with a fountain pen, a fountain pen holder in such a manner that the tension of the fountain pen holder may be easily changed and adjusted.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred form of my invention is illustrated in the accompanying drawings in which Figure 1 shows my fountain pen partly in elevation and partly in longitudinal section;

Figure 2 shows the fountain pen reversed relative to the cap, the pen being shown in elevation and the cap partly in section;

Figure 3 shows a detail view of a piston used in my invention;

Figure 4 a plan view of a washer used in my invention;

Figure 5 a side view of the washer with the surrounding portions of the fountain pen shown in dotted lines; and

Figure 6 a fragmentary elevation of the fountain pen with a valve attached thereto.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made Within the scope of the claims hereto attached without departing from the spirit of the invention.

Referring to the drawings in detail, it will be seen that the barrel 1 of my fountain pen 2 yadapted to receive the pen point 3, While the opposite end terminates in a reduced threaded sectiont provided with a central port 5. A cap valve 6 is adapted to bethread- 35'5 edfon the reduced section, and is formed iwith one or more perforations 7, whichlatter are ldisaligned relative to the port 5 and are in alignment with the material ofthe reduced section l so that when the cap valve is screwed upon its seatthe port 5 is closed The engaging threads of the reduced section 4 and the cap valve arepreferably made to tighten on `a left hand turn, and theA cap valve is formed with a flange 8 which is substantially flush with the outer face' of the barrel. Y

A cap 9 is formed at one end with an internal thread 10 adapted to engage with a registering thread of the cap valve, these two 7 threads being made to allow oft-ightening of the cap turn.

The cap 9vhas a piston 11 reciprocable therein, the piston being providedfwith a suitable gasket 12 `for air-tightly fitting the cap. The upper end of the piston extends beyond the upper end of the cap and has a suitableoperating element 18 threaded thereon. i f

The upper end of the cap is cut olf on an incline as shown at 14 and has the ring 15 of a fountain pen holder 16 disposed thereon, the fountain pen'holder including a spring member 17 extending from the ring 1'5 and adapted to bear upon an object interposed between the fountain pen cap and the spring member. A washer 18 which is cut on an incline at the bottom corresponding to the incline of the top of the cap, overlies the .ring 15 and a gland 19 is threaded into the upper end of the cap so as to tighten the ring 15 and the washer 18 upon the same. f

The lower end of the barrel 1 is threaded above its tapered section as shown at 20, this thread being right-handed and being adapted to receive the open threaded end of the cap9. It will be noted that the piston 11 is cored through a large section thereof as shown at 21 so thatthe cap may `be screwed upon the `upon the cap-valve on a: right hand Vze thread 2O at the pen point end and allow the pen point 3 to be accommodated in the bore.

The operation of my invention will.l be readily understood from the foregoing description. To fill the fountain pen the pen` point is dippedinto a supply of inl whereupon the cap valve 6 is turned sufliciently to remove it from its seat. Next therpiston 11 is pulled upward by means of the operating member 13, which causes suction to be created in the barrel and which causes the inl; to rise within the same. Next the cap valve 6 is screwed downward so that the upper end of the barrel is now closed effectively. The cap may new be removed and the piston returned to its original position, whereupon the cap may be threaded either on the cap valve, if it is desired to use the fountain pen, or on the opposite end if it is not desired to immediately use the pen. It will be noted that the piston does not interfere in any way with the placing of the capvon the pen point end as appears clearly from Figure of the drawy ings. When the cap is in this position the eX- treme end o-f the piston bears against a shoulder 22 on the barrel so as to prevent a tightening of thevcap beyond a desired limit.

The particular means for fastening the fountain pen holder which allows the ring to be held on an incline permits of adjusting the tension of the holder spring. If fastened in the manner shown in Figure 2 lthe tension will be comparatively slight, and this position is used when the member interposed between the spring and the fountain pen is comparatively heavy.v If it is desired to increase the tension, it is only necessary to turn the ring 15 after loosening the gland 19 by 180` degrees or less, as may be desired.

It willbe seen from the above description that a fountain pen constructed in this way does away with the manipulating` means with-in the barrel used at the present time, and also with the sack which latter takes up considerable space and makes itnecessary to make the barrel much larger than is called for in my device,

I claim-r 1. In combination, a fountain pen, a pen holder comprising a ring and a gripping spring extending therefrom and means for fastening the ring to the Vpen at diierent angu-larities whereby the gripping force of the spring on an object interposed between the spring and the fountain pen may be adjusted.

2. In combination, a fountain pen cap having an end cut on an incline relative to the aXis of the cap, a holder including a ring adapted to be seated on the end and having a gripping spring extending therefrom adapted to cooperate with the body of the cap in gripping an interposed object, a washer adapted to overlie the ring and having a bottom face cut on the same incline as the relation.
