11.934, Serial No. llldll e (er. rae-eea) This invention relates to new and useful im1 provements in writing instruments, and more particularly it pertains to such devices as are -commonly known as fountain pens.

In the fountain pen as generally constructed,

inlr is carried in an ink sack from which it is delivered through a feed bar to the Writing point during use of the pen. Such pens, when the inl; supply becomes exhausted, are useless for writing purposes until the ink supply is renewed by refilling the ink sack. The ink sack being of relatively small capacity, the supply does not last a great length of time and it often happens that the supply becomes exhausted and the pen will not, writejust at a time when ink to replenish the supply is not available. It is an object 'of the present invention to provide a novel construction of fountain pen in which, with the use of water, a writing iuid is formed directly in the pen, thus making it necessary to supply, except at long intervals, only water, which is always available, when the supply of writing uid becomes exhausted.

Another object of the invention resides in a novel and simple construction whereby the pen may be easily operated Without removing any of the parts and requiring no special tools for the purpose.

With the above and other objects in view, reference will be had to the accompanying drawing wherein the invention is illustrated in its pre ferred form, and in which,

Figure l is a View in elevation of a fountain pen constructed in accordancewith the present invention,

Figure 2 is a longitudinal 'sectional view partly broken away, the View being on an enlarged scale,

Figure 3 is a view similar to Figure 2, illustrating the construction to a greater degree of detail,

Figure 4l isa-detail sectional View, taken on the line fl*i of Figure l, the view being taken onan enlarged scale, and;

liigure 5 is a distended perspective View.

Referring in detail to the drawing, the reference character lo designates the barrel of the pen. This barrel l0 has one of its -ends open, and at its open end it is provided with an internal screw thread 1l, and an external screw thread 12.

secure the tubular member 17, in said barrel, the

tubular member 17, having an annular shoulder 21, for engagement with the open end of the barrel l0. The tubular member i7,I also has a threaded portion 22, and it is provided with an elongated slot or opening 23, the purpose of which will be hereinafter described.

Th reference character 24;, designates the feed bar of the pen, and except lor the fact that it is provided with an elongated recess 25, it may be of substantially conventional constructionl The feed bar is adapted to be mounted Within the tubular member 17, and is held therein pref erably by friction, the writing point 26, being frictionally held between the feed bar and the tubular member 17.

In assembling the several parts, the leed bar 24, is so positioned within the tubular member that the recess 25, will be inregistration with the elongated opening 23, in the tubular member i7, which permits the insertion into the recess 25, of f an ink stick 30. This ink stick 30, is ci such a character as to be readily soluble in water to pro= vide a writing iiuid which will be delivered by the esA feed bar to the writing point when the pen is in position for use.

Means is provided to retain the ink stick Sil, within the recess 25, of the feed bar and `this means preferably consists of a sleeve 3l, inter1 nally threaded as at 32 for engagement with the external 'threadl22, of the tubular member t7, When screwed home, the inner or rear end oi the sleeve 3l, engages the forward face of the Shoul= der 2l, and closes the elongated opening'23, suf

iciently to retain the ink stick in positon witis in the recess 25, of the feed bar 24. A washer Bel, may be employed at this point to provide a uid tight joint between the inner end of the sleeve and the shoulder 2i.

With the several parts in the position in which they are shown in Figure 3, water in the sack 16', is fed through the feed bar 24, to the writing point 26. In its passage to the writing point, it passes in the presence of the ink stick 30, which, being soluble, provides a writing uid when it is delivered to .the writing point. If the supply of writing iiuid becomes exhausted, it is only neclill? essary to refill the sack 1d, with water in the same manner that it is refilled with ink in the ordinary pen, and water being always available, a pen constructed in accordance with the present invention is never, so long as there is an ink stick 30, within the receptacle 25,-rendered even temporarily unusable.

The ink sticks are of such character thatone will, under ordinary writing conditions, supply writing fluid sufficient for several months use of the pen. A supply of ink sticks may be carried inthe pen, Yand for this purpose, I have shownthe rear end of the barrel .10, as provided with a compartment 40, closed by a screw cap i 41, although this compartment may aswell be provided in the closed end 43, of the cap 15,

if desired.

When it is desired to place an ink stick in the receptacle 25, of the feed bar, it is only necessary to unscrew the sleeve 31, as illustrated in dotted lines in Figure 3, in ,which position,l an ink stick may be freely positoned within the recess 25, of the feed bar.

From the foregoing, it will be apparent that the invention provides a new and novel construction of fountain pen wherein water, which is always available, may be used instead of ink, thus rendering the pen at all times availablefor use:

While the invention has been herein illustrated in its preferred form, itisvto be understood that it is not to be ylimited to the specific construction herein shown', and that it may be carried out in other forms which rightfully fall within the scope of the appended claims.

Having thus described the invention, what is claimed as new and what it is desired to secure by Letters Patent of the'United States, is:

1.'In a writing instrument of 4the type del fluid feed passages leading toand from said nular flange on said feed bar closely adjacent close the opening.
