' Tau whom, it may concern.-

Be it known that 1, JOHN BLALR, asubjeet of the Queen of Great Britain, residing at 1 Brooklyn, in the county of K ings and State of New York, have invented certain new and useful Improvements in Fountain P'ens and I do declare the following to be a full, clear,

it appertains to make and use the same, Tet

erence being had to the accompanying drawtion. .jr .5

. part'of the body in section. gitudi-nal section of the pen enlarged.

' ings, and to the letters of. reference marked thereon, which form a part of this specifica- This invention relates to fountain-pens in which a supplyof soluble ink material is provided in the pen-body and which is convertibleinto ink by contact with water.

The invention includes means for storing the ink material in the pen-body and an improved device for conveying the ink solution to the pen-point when the pen is in use.

The accompanying drawings illustrate the invention.

Figure 1 is a side view of the invention with Fig. 2 is a lon- Fig. 3 is a side of feed-bar enlarged. Fig. 4 is a cross-section on the line a: m of Fig. 1, and Fig. 5 is a cross-section on the'line y y of a Fig. 1.

Like letters of reference in the drawings denote corresponding parts in the several views. y

The letter A indicates the-hollow body of the pen with threaded end to receive the threadednd.hoflthe pen-section B.

O is the cap, adaptedfto fit'ove'r thegroiht D of the pen and having an extension (1 for insertion in the socket e at the rear end of the body A while the pen is in use.

The sectionB has an eccentric opening f lengthwise through it, into which is loosely tittedthe straight tubular feed-bar g. This feed-bar has a short slit h at-its rear end and 5 a longer slit at its forward end, forming at the forward end the fingers i i, the first of which is broken off about midway of its length and the other, 2", is' adapted to lie along upon the nib D, which rests in the space between the fingers. The finger t" is equally efiective on the concave or theconvex side of the nib. The inner part of the front end of the section B iscut away to form a seat j for the pen-nib.

The invention is made operative by adj usting the nib and feed-bar in place. Then unscrew the section-B and pour into the body A soluble ink-powder to the depth of about onehalf inch. Upon this drop a littlewater sufficient to moisten it well. upon it a small wad or plug Z of cotton or other porous material previously moistened with this ink. Now fill the body with water, screw on the section I), remove the cap to the socket e, and the pen is ready for use. The Water is quickly changed into ink,which flows through the hole g in the feed-bar g and out upon the mo,

When the ink fluid is exhausted, refill with water and continue to do this until the powder is all dissolved, when a new supply is put in, as at first.

IVhat I claim, and desire to secure, is-

A fountain-pen having a layer of soluble ink-powder within the closed end of its hollow body a porous plug fitted against said ink-powder, a supply of water in contact with the plug and means for conveying the ink solution through the pen-section to the nib when the pen is held in operative position.

In testimony whereof I aflixmy signature inpiesenceof twowitnesses.
