E. TURNER,
PEN NIB.

ATTORNEYS hurrah stares PATENT MARVIN EARL TURNER, OF LOOKOUT MOUNTAIN, TENNESSEE.
PEN-NIB.
esaaai.
T 0 all whom it may concern. 7
Be it known that I, MARVIN E. TURNER, a citizen of the United States, and a resident of Lookout Mountain, in the county of Hamilton and State of Tennessee, have invented a new and Improved Pen-Nib, of which the following is a full, clear, and exact description.
My invention relates to pens, more particularly to supplementary-reservoir pen nibs, and has for an object to provide a non-leakable and easily operated pen nib for use in enmanship.
For the purpose mentioned use is made of a pen nib comprising an upper side and a lower side, both sides constituting a chamber adapted to contain a liquid and provided with longitudinal serrations, with means at one end of the nib to permit the liquid to feed or flow from the chamber.
In many pens, especially fountain pens, now in use, the ink instead of feeding gradually from the pen when the same is in use, flows onto the writing paper or the like in a rapid stream, thereby causing innumerable blots and often destroying the appearance of the material on which the person is writing, likewise causing rapid destruction to the pen. Furthermore, the drying of the ink at the point of the nib soon makes the pen rusty and tends to effectively clog the same and stop the flow of ink.
In my pen nib the operation of the ink flowing from the nib point is governed entirely by the principle of capillary attraction or cohesion, and as the ink contained in the pen does not appear on the outside of the same except immediately as it is used, a clean pen is provided having a uniform and consistent flow of ink.
Reference is to be had to the accompanying figures, forming a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in Which Figure 1 is a sectional side View of my pen-nib, showing the same attached to a holder; Fig. 2 is a front elevation of the nib; Fig. 3 is a rear elevation of the nib; Fig. a is a sectional view, taken on the line Specification of Letters Patent.
Application filed March 17, 1910.
Patent-ed Apr. 11, 1911..
Serial No. 549,836.
-1-1 in Fig. 2, and Fig. 5 is an enlarged cross sectional view, showing the serrations.
Referring more particularly to the figures, I employ a fountain pen holder 10, of any preferred type, and provided with a reservoir 11, the said holder 10 having a pen nib '12 secured to the holder at the lower end thereof. The pen nib 12 comprises an upper curved side 13 having at one end of the same a longitudinal slit 1 1, and integral with the upper side 13 is a lower side 15 provided with a longitudinal slit 16, both the sides 13 and 15 constituting a chamber 17 open at one end for connection with the reservoir 11, with the other end of the chamber and sides 13 and 15 terminating in a point 18.
By referring to Figs. 1, 2 and 3, it will be easily seen that the slits 1 1 and 16 also terminate at the point 18. On the inner side of the nib 12 and extending longitudinally thereof are a series of serrations 19.
When the pen described is to be used, the reservoir 11 is first filled with ink or an equivalent writing fluid. The chamber 17 being connected with the reservoir 11, the ink tends to flow into the chamber 17 but will not leak out of the slits 14 and 16, as the parts on both sides of the slits tend to push toward each other to make an ink tight joint. When the point 18 is pressed on paper or the like, to write, the slits 1 1- and 1G tend to open and the ink gradually and uniformly feeds onto the paper. In view of the construction described, the ink is drawn from the nib 17 by capillary attraction, thus producing an even and consistent flow of ink and the serrations 19 permit of the ink flowing evenly and uniformly from the pen.
Although I have shown my invention as described, it will be understood that I do not limit myself to this construction, the scope of the invention being fully disclosed in the appended claims.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. A tubular pen nib having feeding serrations on the inner side and extending from end to end thereof.
2. A pen nib comprising an upper side, a

lower side, spaced therefrom and feeding serrations on the inner surface of the sides, and extending from end to end thereof.
3. A pen nib comprising an upper curved side, a lower side spaced therefrom and feeding serrations on the inner surface of the sides, and extending longitudinally from end to end thereof.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. C.
