FILLING DEVICE FOR FOUNTAIN-PEN'S.

Specification ofietters Patent.

Patented Get. it, 1921.

Application filed March 19, 1921. Serial No. 453,579.

To all whom it may concern:

Be it known that I, EDWARD PERINA, a citizen of the United States, residing at Port Richmond, in the county of Richmond and State of New York, have invented new and useful Improvements in Filling Devices for F ountain-Pens, of which the following is a specification.

This invention relates to filling devices for fountain pens.

The simplest and the most effective way to fill the barrel or reservoir of a fountain pen is to use a plunger-especially a'plunger embodying a suction-disk. Plungers' have been used for the purpose just mentioned but because of the lack of some suitable and practical means, fountain pens employing plungers leak, and of course a leaky pen proves a source of inconvenience and a detriment to the owner.

A. fountain pen employing a plunger for the purpose mentioned necessarily should be brought to the extreme end of the barrel.

There should not be any space between the plunger and the end of the barrelthe end of the barrel that does not have the head whichhcarries the writing point. The disadvantage of such a space behindthe plunger invariably results in a vacuum in the space when the barrel becomes warmedsuch as by the heat of the body of an individual carrying the pen, causing the air in the space to enter the barrel beyond the plunger. When the barrel cools, the air returns to the space mentioned and brings with it a quantity of ink. The ink'returned with the air gets on the hands and the a clothing, thus indicating that the pen is impractical toall intents and purposes.

The principal object of the present invention is to overcome the mentioned disadvantages by employing a specially constructed seat and a specially constructed end on the plunger which end will conform to the said seat so that an effective seal between the parts'will be had to revent all possibility of leaking between tlie plunger and the wall of the barrel in which it moves.

Another object of the invention is to provide filling means for fountain pens now be ing marketed without requiring their material alteration, by insertmg in the barrel an extra inexpensive element made of suitable resilient material with which the plunger employed is adapted to coact in the obothers in view, the invention resides in the particular provision and construction of parts hereinafter more fully described and illustrated in the accompanying drawing, in which:

Figure 1 is a longitudinal sectional view partly in elevation of a fountain pen embodying the present invention in the preferred form.

Fig. 2 is an elevation of the plunger reingoved from the barrel of the pen shown in ig. 3 is a longitudinal sectional View partly in elevation of a fountain pen em bodyinga modified form of the present invention.

Fig. 4 is an elevation of the plunger reiqnoved from the barrel of the pen shown in fieferring now more particularly to the drawing for details, it will be manifest that, the'fountain pen 10 has the usual barrel 11-, head member 12, which carries the writing point 13, is equipped with a filling device or means comprising parts to be presently described.

In Figs. 1 and 2, the preferred form of the invention has been shown. In this form of the invention, the same resides in securing in the interior of the barrel 11, a member 14. The member 14 may be cemented or otherwise secured in place in the end of the barrel opposite that which carries the head 12. The head 12 of course is provided with a passage 15 through which the ink may be drawn into the? barrel 11 and through which the ink flows from the barrel to the writing point 13. The member 14 is concaved or beveled to provide a conical seat 15. After the member 14 is secured in place within the barrel 11, the end of the barrel and the member 14 are bored as at 16 for a reason to appear. Ar-

a short stem 19. The disk 18 may be of any suitable flexible material, and it may be secured to the plunger 17 in any suitable manner such as by a small screw, or by cementing. The free end of the stem is coni is against the head 12 and the other end of which isagainst the disk 18. The plunger is beveled as at 22 so as to provide the plunger with a portion which conforms with the seat 15 thus to allow the end of the plunger 17 to be tightly seated on the member 14. The fact that the member 14 is to be made of resilient material, will permit eiiection. of a seal to absolutely prevent the outflow of ink therethrough. The spring 21' serves at all times to'preventtheunseatin of the plunger 17 from the member 14. t will'now be manifest that the only change to the pen 10 is the making of the bore 16 through the end of the barrel thereof, and that the addition of the plunger 17 and its disk 18, the member 14 and the spring 21 will constitute the filling device for the pen.

As shown in Figs. 3 and -4, a modified form of the invention, the filling of the pen is accomplished by the use of a plun er 25 which is manually operable to and r0 in the barrel 11. In this forin of the invention 'there is provided a screw threaded bore 26 instead of a plain bore 16 shown in the preferred form of the invention. The plunger 25 hassecured thereto a-suction-disk 27 at one end and the opposite end thereof is provided with a screw threaded stem- 28 which is adapted for coaction with the bore 26. The'plunger embodies a member 29 which extendsthrough the plunger 25 .to

provide the plunger at one end with means for permitting its reciprocation, and to provide means with which the disk 27 may be secured to the plunger. The means permitting the turning and reciprocation of the plunger 25 is in the nature of a bail 30.

A suitable rod or the like having a hooked be manifest that in this form of the invention the spring 21 is obviated.

The forming of a seal by the employment of the member 14 with its seat and the constructing of the plunger with a beveled portion prevents seeping of ink beyond the plunger. As stated the member 14 is to be made of suitable resilient material which allows the plunger to be brought into contact in a manner which makes for an effective seal between the seat 15 and the beveled portion 22 of the plunger. By confining the plunger normally in the extreme end of the barrel of the pen there is not any possibility of a vacuum to be created because there will be no space therefor.

'\Vhat is claimed is: I

1. A fountain pen including a barrel open at one end and having a bore at its opposite end, a resilient seat at one end of the barrel in proximity to the said bore, a suction plunger movable in the barrel and having a portion thereof normally in engagement with the seat,-a stem on the plunger movable into and out of said bore, the bore allowing the movement of the plunger from the exterior of said barrel, and means for holding the said portion of said plunger in engagement with the said seat.

- 2. A fountain pen including a barrel open at one end and having a bore at its opposite end, a resilient member having a seat at one end of the barrel in proximity to the said bore, a borein said member in a1ine-- ment with the first bore, a plunger having a suction-disk movable in the barrel, a beveled portion on the plunger which engages said seat, and means for holding the said portion in engagement with the said seat.

In. testimony whereof I hereby aflix my signature. I

EDWARD PERINA.
