UNITED STATES FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 714,283, dated November 25, 1902.

Application filed May 20, 1901.

To all whom' t noa/y concer-71,:

Be it known that I, ALONZO T. CROSS, a

citizen of the United States, residing at Provi-A bar for feeding the ink to the nibs of the pen and it consists in a pen-section tube provided with an ink-delivering groove made in its wall above the pen, in combination with a concentric grooved plug which forms with the pen-section tube a concentric annular recess adapted to receive the shank of the pen;

i and it also consists in the combination of the grooved pen-section tube and the concentric` grooved plug with the rotary plug for shutting off the iow of ink from the reservoir when the pen is not in use and in the employment of an elongated closed link for the feed-bar above the pen.

In the accompanying drawings, Figure l represents a` longitudinal section of a fountain-pen provided with my improvement. Fig. 2 represents a side view of the pen-section and a back view of the pen. Fig. 3 represents an enlarged transverse section taken inthe line 3 3 of Fig. l. Fig. 4 represents a side view of a wire link employed as a capillary bar for feeding the ink to the nibs of V the pen. Fig. 5 "represents a perspective view of the grooved central plug of the pensection when employed without the rotary plug. Fig. 6 represents an enlarged longii tudinal section of the pen-sectionof the foun- 5o diameters, the larger portion f tightly tting the bore b of the tube a and its smaller portion ff providing with the bore of the tube et an an- Serial No. 61,182. (No'model.)

nular space g for the reception of the shank of the writing-pen C, a longitudinal slit h being made in the plug e in order to provide the proper yielding elasticity for holding the pen, the plug e being also provided withthe longitudinal groove ,through which air may pass upward into the ink-reservoir, and ink may iiow therefrom to the under side of the pen. The ink-feeding bar j is made in the form of an elongated wire link, as shown in Fig. 4, the ends of the wire being connected together, and the said feeding-bar is inserted above the pen into the groove d, as shown in Figs. l, 2, and 3, and may in some cases be made to extend upward into the ink-reservoir. As shown in the drawings, the feedingbar j extends for a short distance beyond the end of the shank of the pen O, and the spring action of the sidesof the link-formed feeding- -bar will serve to hold the same in its set position within the groove d.

' In order to provide means for closing the ink-passages formed by the grooves CZ and c', so as to prevent leakage from the ink-reservoir when the pen is not in use, I provide the perforated tapering plugm, having the elongated projection n, by means of which it may be rotated, the perforation o of the plug when in the position shown in Figs. .l and 2 being coincident with the groovescl and t', so that a free ink-passage will be provided from the reservoir to the pen; but when the plug is turned at a right angle to the position shown in Figs. l and 2 the said passage will be closed and the ink will be held in the reservoir without liability of leakage.

The grooves d and z' in the pen-s-eotion are made of sufficient size to provide for the ready removal of ink sediment by ordinary means, and a groove p is formed across the end of the protecting-cap D of the pen-section for ICO ployed in connection with the longitudinal groove d.

I claim as my invention- 1. In a fountain-pen, the combination of the pen-section tube provided with the longitudinal groove in its Wall above the pen, the longitudinal plug,y held in the bore of the Vpen-section tube, and provided with a longitudinal groove below the pen, and forming with the bore of the pen-,section tube a concentric annular recess adapted to receive the shank of the Writing-pen, substantially as described.

2. In a fountain-pen, the combination of the pen-section tube provided with the longitudinal groove in its wall above the pen, the longitudinal plug held in the bore of the pensection tube and provided with a longitudinal groove below the pen, and forming with the bore of the pen-section tube a concentric annular recess adapted to receive the shank of a Writing-pen, and the transverse rotary plug adapted for closing the ink-reservoir when the pen is not in use, substantially as described.

ALoNzo T. oRoss.
