FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 235,396, dated December 14, 1880,

Application filed July 3, 1880. (No model.)

To all whom t't may concern Be it known that I, HENRY A. WALKE, of the city of Hamilton, in the county of Butler and State of Ohio, have invented a new and useful Improvement in Fountain -Pens, of which the following is a specification.

This invention relates to that class of fountain-pens in which the holder serves as a reservoir for the ink, which is automatically supplied, during the act of writing, to a pen of ordinary construction.

The object of the invention is to automatically furnish a uniform supply of ink to, the pen when in use, whichsupply is automatically out OK and all leakage prevented so soon as the pen-point is removed from the paper.

Its object is also to regulate the flow of ink to the pen-point, so that the supply may be increased or diminished at will, and a heavier or lighter fluid used, as desired. The means by which these objects are attained are illustratedin the accompanying drawings, in which- Figure 1 is an enlarged side elevation of a pen fitted with my improvements. Fig. 2 is a similar view with the pen-protectin g cap in place on the holder. gitudinal section of the view shown in Fig. l and Fig. 4 is a detail section view of the pen and supply-valve greatly enlarged.

In Figs. 1, 2, and 3 the holder is shown with the central portion broken out.

Similar letters of reference indicate identical parts throughout the various views.

I space between it anda collar, D, to receive the pen 0. The collar D snugly fits the large part of B, below the kuurl b, and securely holds the pen in place.

The lower end of section B is turned inward in the direction of the pen, and its open end is closed by a valve, E, which is carried by the pen.

The valve consists of an elastic washer, 0, large enough to cover the end of the tube B. This washer is held in place against the inside of the pen by ahard-rubber washer, c, which enters the end of the tube, and a metal Washer,

in the direction of the points.

Fig. 3 is a central 1on-.

0 upon the outside of the pen, the whole being held together and in place by a rivet, e, which passes through the washers, and a perforation, one-half which is in each nib of the pen.

The washers e and 0' press lightly upon the pen, so as to permit the nibs to play in writin g and not interfere with the elasticity of the pen.

While any of the ordinary pens in general use may be adapted to my fountain-holder, I have provided one especially adapted to this This improvement consists in making the pen just above the valve thin, and gradually increasing the metal in thickness from there The pen so constructed will yield most just above the valve, and the valve will hence have more play in the act of writing.

The tlow of ink to the pen is regulated in the following manner: The air-tube is made in two sections. The upper section, F, is enlarged to closely fit into the upper end of holder A. Its outer end is provided with a covering-cap, G, and has a transverse perforation, f, to admit air into the tube. The lower section, F, is made to slide within the section F, and is unincumbered in its capability of longitudinal adjustment by the attachment of other parts.

. Its lower end is closed, and near it upon the side of the tube is a perforation to admit air to the reservoir. The flow of ink to the pen is regulated by extending or shortening the airtube, so as to bring the pressure of the air upon a lesser or greater body of the ink. If a limited supply of ink is needed, the tube is extended to near the end of tubeB. If a heavier supply is required, for heavy writing, the section F is pushed within section F.

It is evident that with my extensible airtube good results may be attained, even with the valve E omitted, by jointing the end of the tube B closely to the pen.

' I am aware" of a patent showing a fountainpen the valve of which is secured to one of the nibs, and is automatically opened and closed thereby. By this construction the clasticity of the nibs is made uneven, and the action of the valve will be unsatisfactory unless the nibs are always brought down square on the paper. I avoid these difficulties by hold ing the valve loosely between the nibs of the l 3.

In a fountain-pen, the combination of a reservoir-holder having a bent end, as described, with a pen, 0, and valve E, adapted to automatically open and close the lower end of the holder, said pen being made thinner and more elastic just above the valve, so as to af- 1 ford the valve more play in the not of writing. l
