FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 274,679, dated March 27, 1883.

Application filed April 5, 1882. (No modeLl To all whom it mag concern.-

Be it known that I, HENRY A. WALKE, of the city of Hamilton, county of- Butler, and State of Ohio, have invented certain new and useful Improvements in Fountain Pens, of which the following is a specification.

This invention relates to pens especially intended for use with fountain-holders. Its objects are, first, to form a pen provided at its longitudinal center with a valve adapted to open the discharge-tube of a fountain-holder by the act of writing and close the same when.

the points of the pen are released from pressure; second, to increase the elasticity of the ordinary stub-pen without making it a shadingpen; and, third, to prevent the ink from following up the pen and getting on the fingers when writing.

In the accompanying drawings, in which similar reference-letters indicate like parts throughout the various views, Figure 1 is a plan view of a fountain-holder provided with my improved pen, which is shown in central longitudinal section. Fig. 2 is a transverse section through line a: of Figs. 1 and 3, greatly enlarged. Fig. 3 is a central longitudinal section of the pen and lower curved end of the fountain-holder, the pen-holding sleeve being shown in elevation. This view, like Fig. 2, is greatly enlarged. Fig. 4 is a detail view of a modification of my invention, shown in central longitudinal section. a stub-point pen, such as represented in Fig. 4. Fig. 6 is a detail view, in section, of a commercial or bank pen and the curved end of the ink-tube; and Fig. 7 is an elevation of the pen represented in section in Fig. 6. Fig.1 is drawn to about the full size. The other views are all enlarged.

The pen-holder and ink-fountain A aresubstantially the same as the one shown in my former patent, N0.235,396, dated December 14, 1880, with the addition of a rubber or other elastic disk or washer, B, which is placed over the shoulder of the lower curved section of the ink-fountain, and clamped between it and the Fig. 5 is an elevation of a steel pen, and as these last but a short time it would be too expensiveto apply the valve used with gold pens, and, besides, none of the steel pens now in common use are adapted to use in a fountain-holder, even if the valves used with the gold pens were applied to them, as they are too rigid above the writing-points.

I have invented asteel pen which is perfectly adapted for use with a fountain-holder, and which can be produced as cheaply as any of the steel pens now in common use, and, like all other steel pens, they can be used in any common holder. I have selected two forms of pens toillustrate myinvention, and have shown two forms of valves, which may be stamped up when the pen is formed, either of which will close the ink-fountain when the pen is notin use and open it when the nibs of the pen are pressed in the act of writing.

My preferred form of valve I have represented in Figs. 1, 3, 6, and 7. This valve dis a convex projection, which is raised on the concave side of the pen to enter the counterbored seat in the curved end E of the ink-tube.

The form of valve d shown in Figs. 4 and 5 is concave with respect to the concave side of the pen, and the end of the tube E is turnedoff, so that the valve caps over it when the pen is at rest. In the bank or commercial pen 0, (shown in Figs. 6 and 7,) I find it best to extend the central split up through the valve; but in pen 0, which is stub-pointed, the central slitextends only to the concave or convex valve. All ofthe pens have slitsfextending up some distance above the valve, upon each side of it. The purpose of this is to make the body of the pen more elastic without increasing the elasticity of the nibs. will thus be surely lifted from its seat when the points of the pen are pressed upon the paper.

What I claim, and desire to secure by Letters Patent, is- I 1. The combination of afountain-holder with The valve.

'the'pen-body, and a'valve formed at the longi- 3. The combination, substantially as hereinbefore set forth, of the fountain-holder, the curved ink-tube E, pen 0, and rubber disk or 1 washer B, said washer being held by the tube, and bearing upon the inside of the pen to prevent the ink following up the pen ortube.
