FOUNTAIN-PEN.

SPEI EAT-102 forming part of Letters Patent No. 397,053, dated January 29, 1889.

Application tiled .Tune 20, 1888. Serial No. 277,644. (No model.)

To all whom, it may concern:

Be it known that 1, ROBERT CHRISTOPHER FRAMPTON, a subject of the Queen of England, residing at London, in England, have invented certain new and useful Improvements in Fountain-Pens, of which the tollowing is a specication.

This invention relates to that class ot pens known as tountain-pens,7 and in which the 1o ink is held in a reservoir in thebody or handle oi' the pen and passes to the nib when required for use.

The invention will be best understood by reference to the accompanying drawings, in

I5 which- Figure l is a longitudinal section without the cap or cover and ready l'or use, and Fig. 2 is a similar view with the cap on as it would be worn in the pocket. Both views are rather 2o larger than usual [ull size, though the size is quite immaterial to the invention, and can be varied at pleasure.

The ink is contained in the body or barrel A, to which the intermediate section, B, is

2 5 screwed, and to the section B is screwed the point-section C. A can be readily tilled with inl( when the intermediate section, B, is un-4 screwed from it. In section B is a piece of tlexible tube, preferably rubber tube, D, upon 3o which rests the compressor E, consisting of a thin tlat blade, preterablyot some resilient material-such as steel-(coated, if necessary, to prevent corrosioin) and having a lrounded or equivalent projection, E', which. passes through an opening, l', in the intermediate section, B, as shown in `Fig. l. Sections B and C, may, it' desired, be made in one piece. In the point-secti m (l is a plug, F, having alongitudinal perforation, h, throughout its 4o length, and one or more small cross-perforations, l'i, extemling trom the under side of the plug into the an)rementimicd perforation F. The object ol' the cross-pcrtorat.ion F2 is to admit air or to assist in admitting air to the interior oll the pen.

At FE the perlorat ion l1" opens into both the upper and lower sides, becoming for a shortv distance an open slot, the through-opening upon the upper side extending back as vtar as 5o the crossperforation F2.

The pen-nib G is pushed in between the plug F and the tapering end C oi the pointsection C, which bein slightly sprung, exerts sufcient pressure vto hold the pen tight.

The action ot' this peuis as follows: The 55 reservoir A having been filled with ink, which may be done with one ot the ordinary glass and rubber fillers generally used for filling pens of this class, and the cover or cap II being removed from the business en d ol" the pen 6o and placed upon the reduced extension A ot the barrel, t-he pen is ready tor use, the air requisite toV allow of the flow of ink entering by the openings or perforations F3, F2, and F', and passing through the flexible tube D 65 into the reservoir or interior of the barrel A.

lV hen the pen is to bc closed up, the pointprotectiiig cover Il is removed from the eX- tension A and placed over the point-section (l and onto the intermediate section, B, upon 7o which it rests against the Vflange B2, as in Fig.

2. From Fig. 2 it will also be seen that in pushing on the cover II it has forced in the projecting portion E of the compressor E, with the result that the flexible tube D is 75 squeezed quite tlat, so that the ink cannot pass through it, and the inner end of tube D iitting closely in the inner end of the intermediate section, B, the tlow ot ink to the pen is entirely stopped-the desideratnni when the 8o pen is not in nse.

The projection El need not ot necessity be arched, as shown, so long as an inclined face is presented to the capor cover, so that as the cover is pushed on the projection E is torced into the holder.

U pon withdrawing the cap Il the tube D resumes its normal condition, as in Fig. l, forcing out the projection E, and the pen is again ready for use. The co1n1n'essor E might 9o be merely a solid piece or block; butI vtind in practice that the resilient. portion is desirable, as it conveniently compresses a longer portion ot' the flexible tube. I prefer to have this portion resilient, as stated, as it can be conveniently made out of a piece of watclr spring; but this resiliency is not by any means a necessity, as it is the power of the rubber tube in resuming its normal shape which forces out the projection E. 10o
