FOUNTAIN-PEN.

Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed November 3. 1906. Serial No. 341.899.

To all whom it may concern:

Be it known that I, WILLIAM BoLLEs, of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful Improvements in Fountain-Pens; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which orm part of this specication.

This invention has reference to non-leakable attacl ments ior fountain pens and it has for its object to provide means for accumulating and holding within the pen cap any excess of ink discharged from the pen while being carried about.

The invention comprises the novel arrangement and details of construction hereinafter shown, described and specifically claimed.

In the accompanying drawings Figure l is a sectional elevation illustrative of the invention, the pen cap and the ink retaining member therein being in section; Fig. 2 is a section of the pen cap, the member therein being in full lines; Fig. 3 is a section on the line :rz-x, Fig. 2: and Fig. 4 shows a detached view of the ink retaining member. Y

Referring to the details, l is the pen holder., preferably provided with screw threads as at 2, to permit the cap 3 to be screwed thereon. The nozzle 4 of the holder is provided with a recess having the marginal shoulder 5. Firrnly held within the cap 3 is an insertible ink retaining member 6 of tubular form to surround the pen point, one end of said member being formed with an annular projection 7 to coperate with the shoulder 5 and provide a liquid-tight joint when the cap is in place upon the holder, the opposite end of the member 6 being reduced as at S so that an annular pocket or space a is provided between said reduced portion and the adjacent walls ofthe cap. The extreme outer end ofthe reduced portion 8 is disposed away from the Closed end 9 of the cap to permit any surplus ink discharged from the pen fount and not returned thereto, to find lodgment in the annular pocket surrounding the member 6.

The excessive discharge of ink from a fountain pen is due to several causes. It may result from continual jarring while the individual is moving about, from variation of temperature, causing the material from which the penholder is constructed to contract and discharge the ink, or it may be due to what is usually termed sweating. In the last mentioned cause the ink is deposited in considerable quantities upon the inner walls of the pen cap and gradually creeps down around the pen nozzle, so that the fingers in Writing become soiled by the ink. By the employment of my invention, any ink discharged into the pen cap either mechanically as the result of Sudden jarring, or by condensation of the ink vapor upon the inner Walls ofthe cap, that is by sweating, will either be conducted through the tubular portion of the member 6 back into the pen fount or it will be deposited upon the Walls of the cap and be discharged into and held in the annular pocket, surrounding the member 6. Owing to the tight-fitting joint between the inner end of the member 6 and the pen nozzle the ink is held from being deposited upon the outer or exposed portion of the nozzle.

Having described my invention, what I claim and desire to secure by Letters Patent, is

l. In a fountain pen, a pen cap closed at one end and provided with an annular ink-holding pocket opening in the direction of the closed end of the cap, substantially as described.

2. In a fountain pen, a pen cap closed at one end, and a l member inserted into and held within the cap, said menr ber having the end adjacent to the closed-end of the cap reduced to provide an annular inlcholding pocket opening inthe direction of the closed end of the cap, substantially as described.

3. In a fountain pen, the combination with the pen cap, closed at one end, and the pen nozzle adapted to receive the cap thereon, of a tubular member adapted to be inserted into and held within the cap, the end of the member adjacent to the closed end of the cap beingreduced to provide an annular pocket opening in the direction of the closed end of the cap, the opposite end of said tubular member coperating with the end of the pen nozzle to effect a liquid-tight joint, substantially as described.

In testimony, that I claim the foregoing as my oWn I aix my signature, in presence of tWo Witnesses.

WILLIAM BOLLES.
