FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent N o. 402,417, dated April 30, 1889.

Application filed July 2, 1888.

Serial No. 278,727. (No model.)

reservoir, which reservoir also 'extends into the handle of the pen.

My improvements also consist in certain details of construction, all as particularly hereinafter described. r In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a fount ain-pen made in accordance with my invention. Fig. 2 illustrates different views of the pen proper enlarged. Fig.v 3 shows a blank from which the pen can be made. Fig. It shows my invention in a slightly-different form, and Fig. 5 shows a very simple method of constructing the pen. Fig. G is a modiiication. Similar letters represent like parts in all the figures.

Referring to Fig. l, A representsl a hollow pen v-handle, such .as is ordinarily used for fountain-pens, and which is a part of the reservoir for the ink.

The pen proper consists of an ordinary metal or other pen, d, having two or more nibs, b, at its point, and also having a springtongue, @terminating at its free end over the back of the slit d. The parts a and c are joined together tightly at their edges, so as to form a tube, e, and the tongue c is adapted to press against the pen d. The inner end of the tube e is adapted to be attached to the handle A, so that the connection will be y ink-tight, and this may be done in any appropriate manner-as, for example, by having a screw-threaded extension, f, on the tube e and a female screw-thread in the end of the handle.

In Fig. l `the tube e is shown attached to the ordinary detachableconical end g;-but if the pen and its tube are of larger diameter they may be attached directly to the larger part, C, of the handle and the conical end g may be dispensed with. Vhen the entire pen, including the handle, is complete, there will be a continuous tube or reservoir, g', (see Figs. 1 and 5,) from the lower end of the handle to the free end of the tongue c, and this end bearing against the slit of the pen will keep the outlet of the reservoir closed until the slight pressure in starting to write will slightly press the nibs l) apart and allow enough of the ink to iiow between said nibs and down to the point, when the writing can be accomplished. As soon as the pen is lifted from the paper the pressure on the nibs is removed, the slits are closed, and the outlet for the ink is also closed.

If desired, a wider pen than is shown in Figs. l and 2 may be used, and in this case the pen, with its tongue c, may be attached to the widerpart of the handle and the conical end g may be omitted. The tubular portion e may either be screwed into said portion C or the screw-thread may be dispensed with, as in 4, and the pen simply held in the tube of the handle closely and firmly enough to be ink-tight.

Instead of the tongue c being upon the upper side of the pen it may be upon its lower side,as in Fig. 6. The tongue c is adapted to prevent all flow from the reservoir when the pen is not in use. p

The pen and tongue with their common tube may be all struck from one piece of metal, as l shown in Fig. 3, and then bent around into shape and the edges 7M' soldered together.

A cheap and simple manner of making the entirepen (see Fig. 5) is to strike up the pen and half of the handle in one piece, the tongue and the other half of the handle in another piece, bend the two into shape, and solder the edges 7c k and ZZ together, respectively. In this case the end m of the holder opposite theI pen should be open to allow of the admission of the ink, and this end should then be covered with a cap, n.

My improved fountain-pen does away with the necessity of all feeding mechanism andchannels leading from the reservoir to the pen. Its construction is very simple and there is no interior mechanism to get out of order.

My pen also has the advantage of always having a supply of ink ready for use at the IOO pen itself, :Ls it forms pmt of the ink-reservoir, which extends t0 the slit in the pen, and consequently almost to the point of the saine.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

the pen and the tongue and to the free end of the latter, substantially as shown and described.

In testimony whereof I have signed my name 1 5 to this speci icntion, in the presence of two subscribing witnesses, on this 9th day 0E June,

Afountain-penhaving aspring-tong'ue with A. D. 1888. its free end bem-ing against and covering the slit between the nbs of the pen, and also having :t continuons ink-reservoir, pzu't of which is in the handle and which extends between S. D. DIAS. \Vitnesscs:
