Specification of Letters Patent.

Patented May 7, 1907.

Application filed January 29 1906i `Serial No. 298.432.l

To all whom it may concern.-

Be it known that I, FRANK YEoMANs BRENTON, a subject of the Kin of Great Britain, and a resident of Belleville, in the Province of Ontario and' Dominion of Canada, have invented a new and Improved Fountain-Pen, of' which the following is a full, clear, andexact description.

tities to the pen-point.

The invention consists 1n the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claims. 1

Reference is to be had to the accompanying drawings forming a part of this specifica-1 tion, in which similar characters of reference indicate corresponding parts in all the figures.

`Referring-more particularly to the parts, 1

represents the body of the pen, preferably of a tubular form, as shown, the u per extremity thereof making a threade connection with a bonnet 2. The lower extremity of this body is formed. intoa conical tip or point 3, the extremity of said point present- 1ng an-openin 4 which is choked by a ball 5. Above this balther'e are two other balls 6 and 7,the diameter of each of these latter balls vcorrespondingto the inner diameter of the cone'tlp, sov that each ball rests upon the ball next below, and rests at its sides against the inner face ofthe cone ftip. The mode of ing ball 5 is app ied-to the case or goods to be operation of these balls in feeding 'the ink toward thetip of the pen will be describedv more fully hereinafter. They are held in position by means of a retainer 8 which'consists of a stem 9 havinga presser foot 1 0 attached to the lower extremity thereof. This 'presser-footreferably has substantially the sha e of a reek cross, presenting-four ra' da ydisposed. arms 11. The extremities of thesearms-touch the side of the tubular body, and afford meansv 'fory centering the presser-foot therein, as will be readilyunden stood. To the upper extremity of the stem 9 a plug 12 is attached, the same having the 1 is a longitudinal central section through the pen; and Fig. 2 is a cross section form of a cup, in which is seated a helical spring 13. This spring projects, as shown in Fig. 1 above the plug 12 and thrusts at i'ts upper extremity against the under side of the -bonnet 2.

The conical tip or point 3 of the pen is normallyinclosed 1n a removable' cap 14, asindicated inFig. 1. This cap is simply formed of an elongated cup, its lower portion being of reduced dlameter, as shownsol that an annular shoulder or offset 15 is formed in the inner s ide thereof. The upper portion of the cap fits nicely the diameter of the body 1 so A that the cap vretains itself in position when applied, as will be readily understood. The

function of the shoulder will be described more fully hereinafter. The bonnet 2 described above, has a form which is very similar to that of the cap, resenting a reduced tubular extension l16 will ceive the enlarged op'en extremity vofthe cap when the same has been removed fromv the point in order to use the pen. This means of disposing of the cap when not in use is very common in using ordinary-pens.

chis adapted to re- The ball 5 is of a diameter such as that in# l dicated, which is sli htly in excess of the opening 4, and by .w `ch arrangement this ball seats itself in the opening vso as to rotrude therefrom, at the same time bein held therein. When the pen is to be fille the bonnet 2 is unscrewed and the tubular bod 1 of thepen will be filled with ink in a we l understood manner. This ink is retained and prevented from escaping at the lower end or tip 3 ofthe en, b means of the three balls 5, 6 and 7 W 'ch c oke the opening at this point. The spring 13 aEords means for insurin a rm contact between the faces of the bal sv and between the balls and the cone tip.

When writin with-the pen, the protrud- In order to anticipate any compression of IOO In this way it is con- IIO the air which might take place in applying the oap'14' to the tip of the pen, which oom- Y pression mi ht operate to unseat the choking pressing rsaid balls, I pre er to provide the wall of the cap with small openings 17 which will permit an escape of air, as will be readily understood.

The shoulder 15 referred to above, constitutes va-stop in putting the cap 14 on the tip of the pen, to prevent the endf the cap from ltouching the ball 5 ;otherwise the balls mightl become unseated and allow the ink to escape. Having thus described my invention I claim as new and desire to secure by Letters Patent: o y A fountain pen having a tubular body constituting a reservoir, a ball within Isaid body and protrudin therefrom, a presser-foot all outwardly, a stern attached to said presser-foot and extending tached to the end of said body, a` plug having fitting in said bonnet,v and a spring within said bonnet, the lower portion whereof is surrounded by and seated in said plug whereby said plug protects said spring from contact With the inkwhen the 'pen is fulland tilted from an upright position, said spring affording means for forcing 'said presser-foot downward against said ball.

In testimony whereof I have signed my name to this specification in the presence of I tWo subscribing witnesses.
