PATENT FOUNTAIN-PEN.

l.1IPECIFICATION forming part of Letters Patent No. 302,560, dated July 29, 1884.

Application filed August 3, 1883.

l ing drawings.

This invention has relation to improvements :in fountain-pens, which are fully set forth and described in the following specification, reference being had to the accompanying drawings.

The object of my invention is to lsimplify the valve in such a pen, and to so construct it that the flow of' ink may be controlled by a positive movement of said valve, and when not in use be effectually cut of'f from the pen.

The invention consists in the construction and arrangement of parts, as will be ,hereinafter described and particularly claimed.

In the accompanying drawings, Figure l represents a fountain-pen, partly in section, having my improvements attached, with the resents the same with the pen-nibsv raised as in the act of writing and the valve Opened. Fig. 3 is a perspective view of the pen-holder with the pen removed. Fig. 4L is a perspective view of the double valve as shown in position in Figs. l and 2. Fig. 5 is a central longitudinal section with the single-strip valve. The dotted lines in this figure represent the position of the valve when closed. Fig. Gis a perspective view of the single valve.

B is apen of' common construction, fitted into an annularrecess, B. C is the section, provided with said recess B. The section C is hollow, and provided with inside threads extending from its inner end inward about one-fourth the length of' said section. C2 is a fiange interposed between the barrel A and section C. Said flange is provided with valve-retaining projections C* C5. The valve D liesin a groove, C, in the projection C5. The upper part of said projection is open to admit the spring action of the valve, as shown in Fig. 3. The groove CG is the channel for the iiow of ink.

5o Said groove extends back to the flange C2.

The opening in said flange is round. n

The valve in my fountain-pen is construct- (No model.)

ed of flattened wire, of gold or anyother noncorroding material having spring enough to accomplish the desired object. The outer end of said flattened wire finds a convenient bearing on the under side of the nibs of the pen,

thus forming a conductor for the ink as it passes-outward from the ink-channel. That part of the wire d which passes inward is preferably reduced in width to render it more fiexible, and, reaching nearly into the reservoir, finds a bearing on the upper side ofthe ink-channel. (SeeFig.) Atapointnearly in the center. ofthe mouth of the ink-channel is a pin, g, which passes through the section C, and is secured rigidly in place by riveting at either end. At f is a shoulder e5;- tending upward from the bottom of the longitudinal groove-C6 nearly one-half the height of said groove. Said shoulder f maybe provided by inserting a piece of flattened wire similar to that from which the valve is made, or it may, if preferred, be a solid part of the hard-rubber case, in which the groove is out or otherwise formed. The point D2 of the valve-wire finds a bearing at its outer end against the pen`, at its inner end against the upper side of the `ink-channel, and at a point about one-fourth of an inch from its outer end it also rests on the end ofthe piece which forms the lower side of the longitudinal groove, (see d,) said piece projecting slightly upward, as shown in the several drawings. The outer end of the valve does not bend in the act of writing, its onljT function being to form a valve or cut-off, as at m, which'shall automatically admit or exclude thesupply of ink. The inner end of said wire, when reduced in width, acts as a spring to open the valve when the pen-nibs are raised in writing and pressure on the outer end of the valve-wire is removed, as in Figs. 2 and 4:. d2 is a bend in the valve. is adapted to engage the cross-piece fg and Vprevent the displacement ofthe valve. That part of the wire which bears at d is practically the fulcrum on which the valve-wire oscillates when in use. The valve-wire, by a suitable right-angularbend, (at the point where it intersects the pin g and projection f,) passes downward between f and g, and thence by a similar bend into the ink-channel, as before described. When the pen B is in place in the holder, f and g prevent the valve-wire from This bend IOO moving` endwise, and, when not in operation, Serve to guide the valve m upward tothe position shown in Fig. l, in which the bend first above mentioned engages the upper side of the g would be located near the bottom of the longitudinal groove, the lower limb of D3 passing under said pin. The action of the outer end of the valve-wire is identical, whether formed of a single or double wire, the sole object of the narrowed end being to provide a spring to open the valve when the pen-nibs are raised.

I am aware that a feeder or ink agitator composed of two attened wires riveted together and extending into the reservoir is shown in Lewis patent, No. 272,066, issued February 13, 1883, all of which state of the art is hereby'diselaimed.

Vhat I claim as my invention is- In combination with the holder A, section O, and pen B, the valve D, having bearings and fulcrum, as hereinbefore described, and the spring end extending into the channel, the pin g,projectionf, and thelongitudinal groove, as and for the purpose specified.
