IMPROVEMENT IN FOUNTAlN-PENS.

Specification forming part of Letters Patent No. 140,771, dated July 15,1873; application filed May 27, 1873.

To all whom it may concern:

Be it known that I, JOHN GOODYEAR, of Groton, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Fountain-Pen; and I do p hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, ref-, erence being had to the accompanying drawings which form part of this specification.

My invention relates to an improvement in fountain-pens, and consists as follows:

In the drawings, Figure 1 represents a longitudinal section of my invention; Fig. 2, a plan view of one varietyof the pen-point according to my invention; Figs. 3 and 4:, other varietiesof same.

A represents a tube of any suitable material, and of any desired shape and size. The ends of this tube A are closed by plugs a. Through the center of these plugs, down through the center of the tube A passes a valve-rod, B, which is provided at suitable distances from its ends with valves formed by indentations or fiattenings b. O is the tube terminating in a fine point, on the under side of which is an opening, 0. D represents the usual metal pen-holder, with the pen d in position for writing. E is a camels-hair brush, with a small hole, 0, through its thick or handle part. F is a rubber cap.

To use the pen,-the brush E is first inserted in the tube 0. This tube is then inserted into the metal pen-holder D until its point reaches the slit or division of the pen-points. The tube A with its valve-rod B is then securely fastened in the end of this metal penholder D. The valve-rod B is then drawn up, so as to bring the end I) out of the hole 0 in the end of the brush E, and to allow the valves b to come in the center of the plugs ,a. These valves 1) and plugs a. are arranged relatively to each other, so that when the rod is pulled up the valves are open, and when pressed down they are closed, thus controlling atmospheric pressure and preventing forming a vacuum above. The tube is then filled with ink, and. a small rubber cap, F, placed over the end of the tube to prevent the .ink escaping.

When the pen is in position for writing the ink, by its own gravity, will flow through the tube. The valves being open, it will slowly flow through the brush E in the tube 0, and escape at the proper position on the pen, thus keeping up a constant flow of ink to the point of the pen; but properly retained from too excessive flow by the capillary attraction of the brush until the ink in the tube is expended.

When it is desired to stop writing and put the pen away the valve-rod B is pressed down so as to close the hole 0 in the brush and the openings through the plugs, thus stopping the flow of ink to the point of the pen.

My pen is capable of several modifications, such as constructing the tubes A and O of one piece of any suitable material, putting the brush in the tube so that the brush covers, or it may project from, the orifice in the point of the tube. A plug is then put into the end of the tube, and a rubber cap placed over both to prevent the ink escaping.

The pen may be used just as it is, with the fine glass or other point of the tube as a pen.

The single glass or other tube A may be inserted into the metal holder of a pen, and the ink supplied to the point of the metal pen and the pen used.

In some cases valves may be employed in the tube to regulate the supply of ink, and in others I dispense altogether with them, making the orifice in the end of the tube so small that but a very small quantity of ink can escape at once.

- The forms of valves in the tubes and their mode of operation may vary in many respects.

I do not confine myself to this particular, nor to the precise form or construction of the pen; but

What I do claim, and desire to secure by Letters Patent, is-- 1. A fountain-pen constructed of a tube, A G, tapering to a point, with a brush, E, and valves B b 1) arranged in said tube, by which to regulate the flow of ink to the point, all constructed, arranged, and operating substantially as and for the purposes described.

2. The combination of the valve -rod B, plugs a, tube A, and perforated brush E, all

arranged and operating substantially as and In testimony that I claim the foregoing I for thepurposes described. have hereunto set my hand this 24th day of 3. The fountain-pen constructed of tubes A May, 1873.
