IMPROVEMENT IN FOUNTAIN-PENS.

Specification forming part of Letters Patent No. 147,333, dated February 10, 1.874; application filed November 22, 1873.

To all whom it may concern:

Be it known that I, DAVID L. LAToUnnTTn, of the city, county, and State of New York, have invented a new and Improved Fountain- Fen, of which the following is a specification:

The pen-holder consists of a tubular base, which screws onto the end of a tubular handle, which is the ink-fountain. The ink is shut off from the base byV a disk and packing, or ground metallic joint, near the upper end `of the latter. A feeding-tube extends from this disk down through, out of, and beyond the lower end of the base, along the back of the pen, to deliver the ink upon it. A capillary feeder of thread, wicking, or the like is arranged in the orifice of the feeding-tube, and in connection with the back of the pen,t0 cause an even flow. An adjustable cap is screwed on the lower end of the feeding-tube to regulate the flow of ink, and a spring of peculiar construction is combined with the bascpiece for holding pens of different sizes and forms.

Figure lis partly a side elevation and part] y a sectional elevation of my improved pen. Fig. 2 is a sectional elevationV on an enlarged scale. Fig. 3 is a cross-section on the line wat of Fig. 2, and Fig. 4 is a section on the line 1/ y. Fig. 5 is a detail, showing the arrangement of the spring which I prefer for practical use. j

Sinnilar letters of reference indicate corre spending parts,

A is the tubular fountainhandle, which will, by preference, be made of glass. It is closed at the upper end and open at thc lower end, which is also fitted with screw-threads B, for screwing on the tubular base C, in which is a disk, D, for closing the fountain at the lower end, said disk being made tight by being pressed against the shoulder E in thebase by the end 0f the fountain, with a packingL ring, F, between it and said disk. The disk may be ground to iit tight without packing. From this disk a fcediug=tube, G, extends along down beyond the lower end of the base above the back of the pen II a suitable distance, for supplying the ink to the pen thereat, audit contains a capillary feeder or wick,

I, which extends out through the slot J, and onto the pen, to regulate the feed. The screwi cap K screws forward and back along the slot to regulate the escape of the ink, or stop it altogether by wholly closing the slot. The wick I may extend up through the feeding= tube, as representedin the drawing or not, as may be preferred. Then the flow is to be stopped altogether, the wick may be stuffed in the tube or in the cap.

In practice I will have the feedin gitube bend outward from the pen a little, as shown in the drawing, to facilitate the manipulating of the feed-regulating cap.

The spring-holder I propose to employ for securing pens differing in size and form consists of the thin steel plate L, which isbent double, and attached, by nanges -M at one end,

-to cars or plates suitably arranged at the lower end of the base-tube for the connection of said flanges, so that the spring extends up in the base-piece and back again to the mouth, where the end N, which is doubled back again, so as to bear upon the inside ofthe base-tube, scrvcsto secure the pen by pressing the shank, which enters between the two parts of the opening, against the upper part, and to yield more or less, as may be required for the ad mission of pens differing in shape and size. The handle is detached from the base for filling it with ink.

rlhe capillary feeder is an important element to the successful operation of a fountain-pen, in that it insures the feeding of the ink, and at the saine time prevents the escape of it intermittently in globules, as it does in other arrangements. A piece of wire, or a ne chain, or a hair, will serve well for a feeder; but a thread of fibrous material is the best.

Any surplus of ink that escapes from the orifice of the feed-tube is arrested and suspended between the back ot the pen and the outer surface, and jogs at the point and heel 0f the cap K, until the saine is elaborated and distributed by the capillary thread t0 the point of the pen.

I-Iaving thus described my invention, I clai1n l. The combination of the adjustable cap Q y Mmes;

K, tube G, having slot J, and the capillary thread I, arranged on the upper side of pens, es and for the purpose set forth.

2. The tubular glass handle A, having externztlly-ground neck a, provided with an expen-holder L, so constructed as to ueeounuov date pens of different sizes, und afford the requisite elasticity in Writing, substantially as shown und described.
