FOUNTAIN-fPEN.

SPECIFICATION forming part of Letters Patent No, sisaz, dated october ze, 188e. l Application filed July S, 1866. Serial No. 207,382. (No model.)

.To all whom it may concern: v

Be it knownthat I, ALFRED B. Davis, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Fountain-Pens, of which the following is a specification.

The object of my invention is to construct a simple, cheap, convenient, and easily manipulated fountain-pen, and this object I attain in the manner which I will now proceed to describe. r

In the accompanying drawings, Figure l is a View ofmy improved fountain-pen closed for being carried in the pocket, showing` the caps at the opposite ends in section. Fig. 2 is a longitudinal section of the pen, with the caps at the opposite ends removed ready for lling the reservoir. Fig. 3 is an outside View of the three parts of the casing or holder detached; and Fig. 4 is a view of the reservoir and its parts, pen aud socket all detached from each other.

For yeconomy and ease of manufacture, I make the ink-reservoir A, Figs. 2 and 4, of glass, with an opening at its upper end for the reception of the stopper or cork D, and a curved tapering nozzle, ct, at its lower end for the supply of ink to the pen. I prefer to make the holder for the pen of a socket, E, which simply slips over and binds on the body of the reservoir A, as shown in Fig. 2, so that the pen P can be simply inserted between the glass reservoir A and thesocket E, with the curved nozzle a in contact with the concave side of the pen. The reservoir and the parts attached to it are then passed through the tubular case or holder B, so that the pen and nozzle of the ink-reservoir will project through one end of the holder, while the top of the reservoir and its cap will project at the other end; and in order to insure the retention of the reservoir and pen in proper position in the case B, I form on the upper part of the reservoir an enlargement, a, which abuts against'the end of the case B when the reservoir is inserted therein, as shown in Fig. 2. The body ofthe reservoir is thus inclosed and protected by the tubular holder. The opposite ends, b b', of the case or holder B are reduced in diameter on 5o the out-side for the reception of the caps F and Gr, each provided with small openings f in the sides or ends, for a purpose described hereinafter. The top of the cap F, which fits over the end of the case B to cover the stopper end of the reservoir, has also a reduced portion, f', onto which the cap G, after removal from the pen end of the instrument, maybe applied while the peu is in use.

The stopper D, for the upper end of the inkreservoir, I prefer to make of rubber or other suitable material, and I provide it with a T- shaped or inclined opening, d, by means of which, when the cork is partially pulled out, as shown in Fig. 2, air may have access to the upper-part of the ink-reservoir to let the ink run' freely onto the peu through the nozzle at the lower end.

I prefer to. so proportion the cap F and the length of the stopper D that when the cap F is pressed down to its seat the cork D will be pressed onto the top of the reservoir so far as to close the opening d, and so prevent ilow of ink from the reservoir A through the nozzle,

if the latter should be carried in the pocket in a wrong position.

When the pen is in use, the cap F should first be removed, the cork pulled out sufficiently to allow of access oi' air to the interior of the res; ervoir and the cap then replaced, but not pushed down to its seat. The openings f in the caps F and G, when the pen is in use, will allow of access of air tothe space around the stopper, and thence through the latter to the interior of the reservoir.

With the described construction of pen the reservoir can be filled without the useof the usual filling devices, which have generally to be used with fountain or stylogra-phic pens, for when the stopper D is partially or entirely pulled out the pen can be lled by simply dipping the pen and nozzle end of the reservoir into an ink well or bottle, andthe ink sucked up into the reservoir bythe mouth of the user.

In order to prevent the ink from Ybeing sucked up into the mouth, and also in order to prevent the too rapid flow of ink from the nozzle end of the reservoir when in use, I introduce into the upper end of the reservoir, immediately below the stopper D, a piece of sponge or other porous material, S, and I take IOO advantage of the enlargement a of the reservoir to afford a lodgment for this sponge or other porous material.

The case or holder B and its caps I prefer to form of rubber, metal, celluloid, or other suitable material, so as to afford a neat and light holder, which will at the same time prevent the glass reservoir from being broken by accidental falls.

I claim as my inventionl. A fountain-pen having a holder, and a glass reservoir inclosed in the holder, but detachable therefrom, substantially as set forth.Y

2. A fountain-pen comprising a holder and an ink-reservoir carrying the pen, the reservoir being inclosed within the holder, but detachable therefrom, substantially as set forth.

3. The combination of the holder and its inelosing-caps for the opposite ends with a detachable reservoir inclosed Within the holder, but having at its upper end an enlargement, a', as and for the purpose specified.

6. A fountain-pen having an ink-reservoir provided with an enlargement, a', containing a piece of sponge or other porous material near 'its upper end, substantially as and for the purpose set forth.

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

ALFRED B. DAVIS.
