SELF-FILLING FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 717,873, dated January 6, 1903.

Application iiled .Tune 18, 1902.

To all whom t may concern:

Be it known that I, HENRY B. LEVY, a resident of New York city, Manhattan borough, county and State of New York, have invented certain new and useful Improvements in Self-Filling Fountain-Pens, of which the following is a full, clear, and exact description.

Myinvention relates to fountain-pens, more particularly to that class of fountain-pens known as selffillers;and the invention has for its object to provide a simple, inexpensive, and efficient fountain-pen which is so constructed that ink may be supplied thereto either in the usual manner by means of an independent ink-filler or when desired without the use of an ink-filler, but by so-called seltlling means.

To these ends the invention consists in the novel details of improvement and combination and arrangement of parts hereinafter described aud claimed.

Reference is had to the accompanying drawings, forrning part hereof, wherein- Figure 1 is a longitudinal central section of my improved fountain-pen. Fig. 2 is a side elevation of the cap of the pen. Fig. 3 is a side elevation of the nozzle-section. Fig. 4 is a similar view of the Iiexible ink-reservoir or sac removed from the barrel and attached to a removable section of the nozzle, and Fig. 5 is a cross-section taken on the line 5 5 of Fig. l.

Similar letters of reference indicate like parts in the several views. y

Referring to the accompanying drawings, A indicates the barrel, and B the nozzle-section, of my improved fountain-pen, the outer end or mouth portion b of the nozzle being constricted or narrower than the body thereof. The opposite end of the nozzle-section B is adapted to fit into the barrel A and be held frictionally therein, the edge b of the nozzlesection B engaging an annular rib or shoulder o. upon the inner wall of the barrel A, so as to limit the inward movement of nozzlesection B, an annular rib or shoulder b2 upon the section B being provided for a similar purpose. The nozzle B is provided with a feeder-bar d, of suitable construction, and a pen e, the feeder-bar having the usual or suit- Serial No. 112,167. (No model.)

able ink-ductffor allowing a ow of ink to the point of the pen.

Snugly ittin g into the nozzle-section B and adapted to be frictionally held therein is a tubular section D, having a somewhat constricted mouth d2. (See Fig. l.) It will be seen that the sections B and D practically constitute a single continuous tubular section and that the section lB may readily be withdrawn from the section D when desired. Connected to the end or mouth d2 of the section D is an elongated tubular rubber sac or reservoir F. for containing the ink-supply for the pen; but this sac or ink-reservoir may be made of other material than rubber, provided the same be flexible and yielding. The flexible ink-reservoir E is joined to the section D in any suitable manner, but preferably by simply drawing the mouth e' thereof over and around the constricted portion d2 of the section D, the tubular flexible s ac being of such size in relation to the end of the section D that when drawn over the4 same it will be firmly held thereon by friction without any other retaining means.

F is a cap for the pen of ordinary construction and adapted for use in the well-known manner.

` The barrel, nozzle-section, and tubular section, as also the cap, are preferably made of tin or light metal, but may be made of any suitable material, as hard rubber or the like.

If desired, ink may be supplied to the ilexible ink-reservoir E of my fountain-pen in the ordinary manner of fountain-pens-to wit, .with the aid of an ink filler or dropper-in which case the nozzle-section B is withdrawn from its position upon the section D, whereupon ink may be poured directly into the inkreservoir E through the section D by means of an ink iller or dropper, or, if desired, my pen may be supplied with ink by withdrawing or pulling the barrelA from over the iexible reservoir E and connected parts-z', e., the nozzle B and section D-then firmly twisting or pressing the rubber sac E, so as to eject air therefrom, and while the pressure is thus applied to the` sac E, dipping the pen-point into an ink-well or source of ink-supply, and then by releasing the pres- IOO sure upon the flexible sac E, ink will be drawn by suction into the same, the ink flowing along the duct or ducts in the feeder-bar into the nozzle B through the section D and into the reservoir E.

It Will be seen that by my construction of fountain-pen, Where for some reason or other the self-filling function thereof should become inoperative, ink may nevertheless be readily supplied to the flexible ink-reservoir E by withdrawing the section B from the section D and utilizing an ink-filler.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

l. A fountain-pen of the character described, consisting of a barrel, a nozzle frictionally held by the barrel and comprising two separable sections one of which is adapted to snugly fit Within the other and be frictionally held therein, the outer section of the nozzle carryinga pen and feeder-bar provided with ink-ducts, and a flexible ink-reservoir connected to the inner nozzle-section, substantially as and for the purpose herein shown and described.

2. In a fountain-pen of the character described, the combination of a barrel, a nozzle-section having a feeder-bar and pen mou nted therein, a tubular section engaging the nozzle-section and removable therefrom, and a iexible ink-reservoir connected to the tubular section, all arranged so that the nozzle, tubular section and ink-reservoir may be withdrawn from the barrel by an outward pull of the nozzle, substantially as described.
