Application and January 18,1906. semi No. 296.681.

To all whom it m/tj/ concern:

Be it known that I, WILLIAM A. WELTY, a citizen of the United States, residing at Waterloo, in the county of Blackhawk and State of Iowa, have invented a new and useful Fountain-Pen, of which the following is a specification.

This invention relates generally to fountain-pens, and particularly to a novel form of feedbar therefor.

The object of the invention is to provide a feed-bar which in a novel and ink that might gather around the pen-point when the pen is nearly empty, thereby to prevent bleeding and blotting, and also of storing a sufficient quantity of in k to kee the main ink-duct moist for quite an exten ed period of time, whereby the vpen will always start to write upon demand, and thereby obviate the annoyance and loss of time that ensues where the main ink-duct has become dry and refuses to feed the ink `to the pen in proper quantities.

A further object is to dispose the air-duct at such point relatively to the terminals of the feed-bar as to overcome any 4tendency of the ink to run out and soil the outside of the feed, and, further, to relieve the main inkduct or the greater portion of it from the retarding action of the air.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in a novel feed-bar for fountain-pens, as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, -and in which like l s's characters of reference indicate corresponding parts, Figure 1 is a view in perspective of a feed-bar constructed in accordance with the present invention and viewed from the upper side thereof. Fig. 2 is a View in plan of the under side of the feed-bar. Ifig. 3 isa ransverse sectional view through the feed- Referring to the drawings, 1 designates the feed-bar, which is provided with a main inkduct 2, that extends practically throughout its entire length and is intersected intermediate of its ends by an air-passage 3, that extends transversely through the bar, preferably at right angles to its length, and communicates with an air-duct 4, disposed on the under side of the bar in alinement with the practical man- `ner shall be capable of holding any surplus main duct and that extends from the airduct outward and communicates lat its forward end with the air, thereby to cause the air to vpass to the main ink-duct by a short and direct passage instead of having to traverse the entire length of the bar, as is usual. By disposing the air-passage at the point shown 1t will lie wholly within the pen-section, and thereby minimize the retardin action of the air upon the ink. On each si e of the main ink-duct and extending nearly to the outer end of the bar and terminating,

preferably, in alinement with the end of the 4 main ink-duct is a subduct or channel 5, the

two constituting storage chambers or reservoirs for holding to retain the main ink-duct in a moist condition for quite 4an extended period of time and which w1ll readily flow to the pen the instant the latter is brought into contact with the pa er.

s will be seen by reference to Fig. 1, there is no dlrect connection between the resera sufficient quantity of ink voirs and the main ink-duct; but there is an indirect one resulting from capillary traction that will cause the ink in the subducts to be fed to the main duct when the en is in use. In addition to storing the ink fbi` the purpose stated the subducts will operate to hold any surplus ink that might gather around the pen-point when the pen is nearly empty, thereby preventing bleeding and blotting in a practical and positive manner. When a penis properly combined with the feed-bar and the two are placed within the pen-section, external air will positively be excluded from the reservoirs, inasmuch as these terminate short of the end of the bar, whereby the ink contained therein will be prevented from drying and clogging.

By., the arrangement herein shown the objects sought are secured in a thoroughly feasible and practical manner, and experiments have demonstrated that when a feed-bar is constructed as described the pen, so long vas the reservoirs contain any ink, will always start instantly to write, thereby obviating a serious objection urged by many against the use ofl fountain-pens.

I claimc 1. A feed-bar provided with a longitudinal IOO ink-duct and with an elongated longitudinally-disposed ink-reservoir on each side of the duct, said reservoirs being closed at the bottom and out of communication with the IIO dinal ink-duct extending througghouit presti- :my

cally the entire len th of the ar, said bar having a short aiI- uct in its other side.. and having an airassage connectingv the ducts, and said bar a so having elon ated ink-reser- 1o voirs at the sides of the inkuct and out of dinectcoxmnmnicationx with said duet and the air-duct, the bottoms of said receptacles bel in permanently closed.

n testimony that I claim the foregoing as in the presence of two witnesses.
