ATES raraur RICHARD H. STEVENS, OF-SYRACUSE, NEW YORK, ASSIGNOR TO L. E. WATERMAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
FOUNTAIN PEN.
Specification of Letters Patent.
Patented Dec. 2, 1913.
Application filed January 9, 1912. Serial No. 670,226.
To all whom it may concern:
Be it known that I, RICHARD H. S'rnvmvs, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Fountain-Pens, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.
This invention relates to improvements in fountain pens and has particular reference to means for regulating the feed and flow of the last few drops of ink in the reservoir.
In the use of fountain pens now in use, it has been found that the user should not, to get the best results, allow the reservoir to become completely exhausted for the reason that the air pressure is so great upon the last four or five drops of ink as to cause it to flow too freely and blot the work. In fact, manufacturers of fountain pens are particular to request that the reservoir of the pen be not allowed to completely exhaust itself.
My object therefore is to produce a device which will overcome these difliculties and allow all of the ink to be used without allowing the excess flow of the last few drops. Not that there is any economy in using the last few drops of ink, but because it is unpleasant to have the work disfigured by an excess flow of ink. I have discovered that this objection may be overcome by securing in the bottom of the ink reservoir a frame of some character, which shall retain, by capillary attraction or otherwise, the last few drops of ink and allow it to be given down to the pen gradually.
In using the word frame I do not limit myself to any particular form of frame or any particular material from which it is to be constructed for the reason that I have dis covered that it may be of most any form or of most any material, and equally perform the function required. I have also discovered that a piece of absorbent material, such as felt or the like, may be employed to ad vantage.
Having the above objects and uses in mind, my invention therefore consists in the several new and novel features of construction and operation hereinafter described, in
connection with the accompanying drawings, which form a part thereof.
Figure 1 is a view of a fountain pen. Fig. 2, the ink reservoir. Fig. 3, the pen-holding plug. Fig. 4, a longitudinal section through the plug, showing the ink channel and a preferred form of inkretaining-frame. Fig. 5 is a view of the ink-retainingframe, detached. Fig. 6 is a view similar to Fig. 4, cut away, and showing a modified form of inleietaining-frame.
The fountain pen A- is composed of the usual reservoir l which may be threaded, and the pen-holding plug 2-, which may be likewise threaded in order to afford suitable connection between the two parts and for retaining them in operative position, the end of the plug -2- forming the bottom of the ink reservoir when the pen is in use. The pen-holding plug 2 may be constructed in any suitable way and has an ink channel l communicating at one end with the pen and its opposite end with the ink in the reservoir.
5 is a groove upon one end of the plug and serves to direct the ink from the bottom of the reservoir toward the channel l-.
Upon the end of the plug which forms the bottom of the reservoir, I erect a frame 6, the word frame being used in the absence of some other appropriate term, and consists, as shown in the drawings in Figs. 8, 4t and 5, of a piece of wire spirally wound and held in position by inserting the stem 7 into an opening in said plug. This frame may consist, as stated above, of a spirally wound wire, or it may consist of an upright of some character, having off-sets 9 as shown in F ig. 6, adapted to attract to it the last few drops of ink in the reservoir and allow it toflow gradually through the channel 4 for the purposes indicated, and thereby prevent blurring and blotting.
Having described my invention, what I claim is A fountain pen comprising a hollow body portion closed at one end, a plug for insertion in the other end, said plug having a substantially fiat circular inner end, the edge of which is in contact with the wall of the body portion and provided with a relatively small In witness whereof I have hereunto set my conduit, leading from the hollow body to hand this 5th day of January, 1912.
the pen, and a frame secured to the inner end of said plug and out of contact with the RICHARD STEVENS walls of said conduit, for exercising capil- Witnesses:
lary attraction to regulate the flow of the EUGENE A. THOMPSON,
last few drops of ink. E. F. TUCKER.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. 0.
