FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 406,375, dated July 2, 18389. Application led December 13, 1888. Serial No. 293,463. (No model.)

.To all whom, t may concern.:

Be it known that I, CHRISTOPHER STOCK- MANN, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Fountain-Pens, of which the following is a specification.

This invention relates to that type of fountain-pens wherein the pen-holder and inkfeeder is arranged at one end of a hollow handle and is composed of a plug having an ink-duct and a slot, so that the ink is supplied to the back of the writing-pen by the action of the split pen-point.

The object of my invention is to improve the construction of the feeder, whereby an increased quantity of ink can be caused to How to the back of the pen, when desired, without liability of blotting.l

The obj ect of my invention I accomplish by the features of construction hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l represents a vertical central section. Fig. 2 is a transverse section in the plane a? Fig. l. Fig. 3 is a similar section in the plane y y, Fig. l. Fig. 4 is an elevation of the feed-plug, showing its back. Fig. 5 is a similar view showing the face of the feed-plug.

Similar letters indicate correspondin parts.

In the drawings, the let-terA designates the usual hollow handle or reservoir to contain the ink, provided at its closed end with the usual nipple a, to receive the cap B when the pen is in use. The opening at the other end of this handle is threaded to receive the penplug O, which is hollow to receive the feedplug D and provided at its outer end with a socket b, similar to the pen-receiving sockets of ordinary pen-holders.

The feed-plug D is provided with a tongue c, which extends through the socket b over the top of the pen E, so as to cover a portion of the slit of the pen, as shown inFig. l. The

body of the feed-plug D is cylindrical and made to fit snugly into the pen-plug C, and such feed-plug is formed or provided with two longitudinal channels d d, terminating, respectively, at their outer end portions in openings e e, that extend transversely through the tongue c. rlhe channels d d are separated by a longitudinal rib d', extending continuously between them and terminating beyond the transverse openings. If a full supply of ink is required, both channels are left open; but if it is desired to reduce the supply of ink to the pen one of the channels is stopped up by a suitable plug.

At the inner end of the feed-tongue c is formed a shoulder g, and the pen is so adjusted that its tail end abut-s against this shoulder, or nearly so, and that the ink which passes from the ink-reservoir A down through the channels d passes through the openings upon the back of the pen,and then down between the feed-tongue and the pen, the flow of the pen being promoted by the motion imparted to the nib of the pen in writing.

An air-hole f may be made in the concave portion of the pen-socket l) to prevent a vacuum in the ink-reservoir.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the ink-reservoir A, of the pen-plug having a pen-receiving socket, and the feed-plug made to lit the interior of the pen-plug and having two channels d d, separated from each other by an intervening ridge, and a feed-ton gue having two openings e e, one for each channel, substantially as described.

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