Toi aZZ whom it may concern:

Be it known that I, FRANCIS C. BROWN, a citizen of the United States, and a resident of New Brighton, in the borough and county of Richmond, city and State of New York, have invented certain new and usefullmprovements in Fountain-Pens, of which the following is a specification.

M invention relates to fountain-pens, and has` or its object to provide, improved means for holding a body of ink adjacent to the nib or writing-point and also for preventing a bending of the nib-carrier.

The invention will befully described hereinafter and the features of novelty pointed out in the appended claims.

Reference is to be had to the aceompanying drawings, in which- Figure-1 is a longitudinal section of a portion of a fountainpen embodying my invention. Fig. 2 is a top view of the init-retainer om )loyed by. Ine. Fig. Sis a bottom view of suc ink-retainer. Fig. 4 is a cross-section online 4 4 of Fig. 2, and Fig. 5 is a cross-section online 5 50i Fig'l.

A indicates the barrel of the pen provided with a contracted mouth A', adapted to rc ccive the forward end B of the nib-carrier or feed-bar, which in the particular .construction illustrated has a rearwardly-extending stem B for slidingl the nib C into and out of the barrel by any suitable mechanism; but my .invention is not restricted to pens having retractible nib-carriers. The nib-carrier is rovided with an upper feed-tongue D and a flower feed-tongue E, provided with longitudinal slots D and E, respectively, and adapted to receive the nib C between them. The .rear end of the nib lits into a suitable scat kof the nib-carrier B', as shown in Figs. 1 and 5.

A brace l" extends from the lower portion of the nib-carrier B into engagement with the forward portion of the lower tongue E, leaving a space between the main portions ofsaid brace and lower tongue. In this space is located the inleretainer G, which is provided on its upper face with two longitudinal grooves G and on its lower face with a series of transverse grooves (l2. 'lhe inkrctaincr preferably is not of out, but is provided with cut-out portions G3 at regular intervals, so vas to form a series el' spaced arms Gt.' The combined depth of the grooves G and GL is greater than'the thickness of the ink-retainer, and thus theintor section of the longitudinal and transverse grooves produces two series of through-apertures G5 at each side of the longitudinal central body Gl of the ink-retainer. The forward portion of the ink-retainer may be rounded, as shown at G7, to facilitate the insertion of said retainer in its place. The ink is fed to the nib through the feed-space vIl,

which is shown upon an'exaggerated le in Fig.' 5 and also through the slot D ci u per tongue D. 'lhe ink also passes from t e ower part of the channel Il to the lower surface of the nib, to the lower tongue E., and to the ink-rctainer G. The grooves on the lower su rfaco of said ink-retainer form means for holding a considerable quantity of ink, it being understood that the grooves are so small as to hold the inl'. by capillary attraction, the drawings represcntinglthe construction upon a-very much enlarged scale. The apertures Gi will allow the ink to pass from the lower surface of the retainer G to the upper surface thereof, so'as to reach the nib C through the slot E of the lower tongue E.

Whilel have described the ink-retainer G as a separate piece, this is not essential to my invention, and, if desired, the ink-retainer may be made integral with some other partof the device-ats, for instance, the lower feed,

tongue E.

In order to brace the nib-carrier B', especially when such carrier is retractable, as hereinbefore referred to, .l provide tion a pinBg, arranged to project close inner wall of the barrel A, so as to limit and practically prevent any bending of the nibcarrier.

1. In a .fountain-pen, the combination of the upper and lower feed-tongues adapted to receive the nib betwcenthem, the brace arranged to engage the forward portion of the lower feed-tongue, and the ink-retainer located betwecn the lower feed-tongue and the. brace and groovcd transversely on the side facing said brace.

2. ln a fountain-pen, the combination of the upper and lower feedftongues adapted to receive the nib between them, the brace arranged to engage the forward )orticn of the lower feed-tongue, and the in r-retainer located between the lower feed-tongue and the brace and grooved lengthwise on the side facing thel lower tongue and' crosswise on the side facing said brace.

3. ln a fountain-pen, the combination, with a feed-tongue one side of which is adaptat its rear por- 4 v to thel roo IIO

edv to engage the nib, of an ink-retainer arranged on the other side of said tongue and seperate therefrom, said ink-retainer being provided with transverse grooves on the side facing away from said tongue. V

4. In a fountain-pen, the combination, with a feedetongue one side of which is adapted to engage the nib, of an ink-retainer arranged on the other side of said tongue and grooved lengthwise on the side facing the feed-tongue and crosswise on the opposite side.

5.'In a fountain-pen, the combination, With a feed-tongue one side of which is adapted to engage the nib, of an ink-retainer arranged on the other side of said tongue and grooved lengthwise on the side facing the feed-tongue and crosswise on the opposite side, the said grooves intersecting so as to 6. In a fountain-pen, the combination,

with a feed-tongue one side of which is adapt ed to engage the nib, of an ink-retainer arranged on thevother side of said tongue and separate therefrom, said ink-retainer being provided With transverse grooves on the side facing away from said tongue, and with passages or openings leading through from one side of the ink-retainer to the other.

'In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FRANCIS C. BROWN.
