IMPROVEMENT IN FOUNTAIN-PENS.

-The Schedule referred to in these Letters Patent and making part of the same.

pens, and consists in an arrangement of the piston,

whereby the ink is drawn into the barrel, so that a passage may be readily opened, after the ihk is drawn in, to admit atmospheric pressure from the top, to' cause the ink to feed.

It also consists in improved arrangements in connection with the delivery-passage, of a outoi` plug or valve, for regulating the feed, or 'stopping it entirely when required.

Figure 1 .represents a sectional elevation of my improved pen; v

Figure 2 is an elevation of a key used forl adjusting the valve; and

Figure 3 is an elevation of a cap for covering the end of the pen for protection when not required for use.

Similar letters of reference indicate corresponding parts.

A is the barrel or fountain;

B, the piston; and

C, the piston-rod.

The said rod screws into and out of a screw-threaded socket in the piston, for connection or disconnection therewith.

At the bottomv of this screw-threaded socket is a small perforation, D, extending through the piston, the said perforation being about the same size as the receiving and supplying-passage E,

This passage D is closed by the point F of the rod, when screwed home to work the piston for drawing in` the ink, but when the supply has been taken in, the point of the rod isscrewed out, and the rod drawn out of the barrel to admit atmospheric pressure ou the top, to force the ink through the supply-passage E, instead f doing it with the piston as now practised. This gives a constant and uniform pressure, which needs no attention, except to regulate the opening of the supply-passage E. For this purpose a screw-plug or valve-Cr is provided, and arranged with the angular passage E, so as to screw down upon a conical seat, H, in a part of the passage in thepsame axis with the valve, the smooth end of said valve flttin g so snugly as to prevent the access of the ink to the screwthreaded part I.

This valve is arranged as near to the mouth K of the passage E as it can well be, and thereby prevents the'discharge of an excess of ink. It is provided with a square head for turning bya socketed key, L.

A pen of ordinary or suitable construction is employed, and is held, as shown inthe drawing, between a tubular detachable section' of the barrel B and a screw-threaded tubular piece, into which is screwed the tenon of the part in which the angular passage E is formed.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- 1. The arrangement ofthe removable piston for opening a passage ipr the admission of atmospheric pressure to force the ink down to the pen, substantially as specified.

2. The arrangement, with the supply-passage E, of

the regulating-plug or valve G, fitting the conical seat,

to close the passage -to the mouth K, and also to prevent the escape of ink, substantially as specified.
