FOUNTAIN-PEN.
Specification of Letters Patent.
Patented Oct. 13, 1908.
To all whom it may concern:
Be it known that I, ALONZO T. CRoss, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improve nient in F ountain-Pens, of which the following is a specification.
My invention consists in the improved combination of a gravitating spherical valve, with the upper end of the air-duct of the pen section, whereby the ink will be prevented from escaping from the ink reservoir when the pen is not in use, and whereby the action of the ink in its How to the pen will be regulated.
In the accompanyingdrawings, Figure 1 represents a longitudinal axial section of a fountain pen provided with my improvement. Fig. 2 represents an enlarged aXial section of the pen section of the fountain pen. Fig. 3 represents an enlarged side view of the air-duct plug, showing the inkduct for leading the ink to the under side of the nibs of the pen. Fig. I represents a transverse section taken in the line 4 A of Fig. 2. Fig. 5 represents a longitudinal section of the plug showing a modification. Fig. 0 represents a side view of the perforated cap of the valve chamber of the airduct. Fig. 7 represents a view of the inner end of the said cap.
In the drawing, A represents the barrel of the ink reservoir, which is closed at its upper end, B the pen section, and C the cap for covering the pen section when the pen is not in use. The pen section B is provided with the external screw thread a, which engages with the internal screw thread o of the barrel A, the said pen section being also provided with a bore c, which is preferably made of slightly increased diameter at its to form in connection with the inner wall of the pen section, a duct for the passage of the inl; from the reservoir A to thernibs of .the writing pen E, the said writing pen being held between the periphery of the plug I), and the inner wall of the lower end of the pen section. The valve F is preferably made in spherical form, of lead or other suitable metal, and as shown in Figs. 1 and 2, is retained in the valve chamber c by means of the transverse wire g, but in Fig. 5 a perforated cap Gr is employed to retain the said valve loosely in the said valve chamber, the inner face of the said cap being provided with the bosses L, IL, whichl serve to allow the free passage of inl: under the valve when the writing pen is turned upward.
When the pen is in use the action of the ink as it iows through the ink-duct to the pen serves to raise the valve F rhythmically from its seat, and thus allows the passage of a bubble of air through the valve chainber to the ink reservoir, when required.
I claim as my invention:
A fountain pen provided with an ink-duct adapted for the passage of ink from the reservoir to the writing pen, and having an air-duct leading upward to the ink reservoir, and an automatic valve adapted to close the air-duct, to regulate the flow of ink to the pen.
