FOUNTAIN-PEN.

Specification forming part of Letters Patent No. 40.l35.dated September'29, 1663.

- To all whom it may concern..-

Be it known that I, JOSEPH WELLER, of in the county of Fayette and State of Ohio, have invented a new and Improved Fountain-Pen; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, making part of this specification, in which- Figure 1 represents a side elevation of my invention. Fig. 2 represents a longitudinal central section of the same.

Similar letters of reference indicate corresponding parts in both figures of the drawlugs.

The nature of my invention consists in a novel contrivance in a fountain-pen, whereby the penman or user of the pen is enabled to supply the nib with. fluid according as it is needed for either a fine or coarse handwriting without lifting his hand from the paper, and also to prevent the pen being surcharged with fluid when in use or not, all as will be hereinafter fully explained.

To enable others skilled in the art to which my invention appertains to understand the same, I will proceed to describe its construction and operation.

A represents a tubular case, which may be made of sheet metal, silver, gold, or of any other suitable material. This case constitutes both the fountain and holder of the pen, and itis provided on the inside and lower end with a screw-thread to receive the screwthreaded end of the tube a, through which the fluid passes from the fountain to the pen. The tube a is furnished immediately behind the screw-thread on its upper end with a square shoulder, which,'when the two tubes A and a are united together, comes in close contact with the lower end of the tube A, and forms a tight joint, thus preventing any escape of fluid other than at the. lower and discharging end of the tube a. The aperture which extends through the tube a, at its lower end, opens out at one side of the tube, and at its upper end is countersunk to receive a shoulder, b, of corresponding form onthe central rod, B. This rod'is made of metal, andextends through a small aperture in the top of the tubular case, where it is provided with a fixed collar, n, and plug '5, and connected by a pivot with one end of a rocking lever, O. The

plug '5 is simply a tapering rod, which, when in its lower position, enters and closes an airvent in the top of (the fluid-fountain.- portion of the rod B which extends below the shoulder b tapers gradually to a point. p The lever O and upper portion of the central rod, B, are iucascd in a tubular cap, 0, which is screwed on the outside and upper end of the tubular case A. The cap cis provided on the inside with a. partition having two apertures formed in it-one for the central rod, B,to work through, and the other for a rod, D, which extends down on the outside of the tubular case and serves as a medium through which the conical shoulder or stopper b and plug 43 are simultaneously raised to open their respective apertures when it is desired to charge the pen with fluid. The rod D passes up on the inside of.the,cap c, and connects with oneend of the rockiuglever O, the central rod being connected to the other. The rocking lever 0 moves on a. fulcrum, e, which is supported atits ends in the sides of the cap a. A helical spring, E, interposed between the partition and upper side of a fixed collar, n, on the central rod, B, acting through the rod B, forces the conical shoulder or stopper 1) into the countersink in the tube a, andat the same time by means of the plug [closes the air 'ent, and thus prevents the escape of fluid when pressure is not being applied to the rod. The rod D. terminates at bottom in a foot, f, which stands at right angles with the rod, and it (the rod) is kept in place on the tubular case by a ferrule, 9, through a slot, in which it is allowed a free upand-down movement. The pen is fastened to the tube by a ferrule, 71, as clearly shown in Fig. 1

In writing with my improved fountainpen the second finger of the hand in which the pen is upon the foot of the rod. A slight pressure then applied to this foot with the second finger will raise the plug 6 so as to open the vent, and thus admit air into the fountain, and simultaneously therewith raise the stopper 1) a suflicient distance to allow the fluid to pass into the countersink of the tube a, whence it is conducted by the tapering rod to thepen. The moment the foot is relieved That held should be allowed to restof pressure the helical spring returns the stopper to the countersink and the plug to the vent, and thus stops the further flow of i fluid. I

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y 1. The central rod, B, provided with a conienl shoulder or stopper, 'b,' adapted tofit a countersink in the converging tube a, in combination with the rocking lever 0,. rod D, and

helical spring E, when arranged to operate in the manner described.

parts, the plug 2', attached to the rod 13, and servingto open and close an air-ventage in the fountain, in the-manner and for the purpose described.
