tain Pens, "of which the following a specification.

rllhis invention relates to fountainy pens.

' .'lhe .object of the invention is to provideV a fountain pen of a novel structure which isV ecient in operation and economical to manufacture.

A further object of the invention 1s to provide a fountain pendesigned to employvv ink in its solidified or powdered form and to maintain a supply of writingI duid by replenishing the penwlth any suitable liquid,'such as water, or the like.

.d further object of the invention is to proi vide a fountain pen which. requires'filling the same with water to obtain the *writing duid.

` @ther objects of the invention will y be more fully set forth hereinafter;

rllhe invention consits substantially in the construction, combination, location andrela tive arrangement of the parts, all as will be more fully hereinafter set forth, as shown in' the accompanying drawings, and finally pointed out in the appended claims.

Referring to the drawings lFig. l is a viewin longitudinal section of a pen 'embodying our invention.

lFig.. 2 is an enlarged sectional view on the line 2--2 of Fig. l, looking in the direction of the arrows;y f

lFig. 3 is a sectional view taken on the line 3-3 of Fig. l, lookingv in the direction of the arrows;

Fig. 4L yis a fraentary view of the nib portion of the fountain pen of a slightly modied construction embodying our inven- Fig. 5 is a sectional view, taken on the line 5 5 of lfig. la and looking in the direction, of the arrows.

"lhe same part is desiatedl by the'isame reference character wherever it occurs throughout the several views. llt is among the special purposes Aof our present invention to provide a pen equipped with ink making material, that is, a material which, when provided with a suitable liquid, such as water, willl form a writing fluid, and wherein the ink making material is positioned between the pen point and the usual barrel of the fountain pen, the fluid belng supplied to the fountain pen barrel in the usual or in any desired manner.

ln accordance with our invention, we show in the drawings the usual fountain pen provided with the barrel l containing the usual Achamber 2 for a suitable fluid, such as water. Water may` be supplied to the charnfor allowing the chamber 2 to be filled, we do not desire to be limited or restrictedin this respect. lln the arrangement shown we provide an end block l provided with interior threads adapted to screw into and close theend of the barrel 1. ,D lf desired, and

as shown, the block may have incorporated therewith a chamber 5 to store additional or extra ink pencils, powder, or the like. ln this instance, the block Il isprovided with exterior threads which screw into and engage interior threads located at the end of auxiliary `chamber 5, said chamber being provided with exterior threads which engage interior threads of the barrel l. 'llhe foregoing arrangement, however, is confined to details to which our construction is not directed. The opposite end of the barrel 1 isf` provided with lnterior threads to recelve therein the usual nib support 6. The n1b or feeder illustrated at 7 is of a special construction and consists of a cylindrical por-v materialwhich, in the. orm shown, is illustrated as an ink stick 13, soluble. in suitable liquids, such as vuater, is located in the chamber 9 of the nib 8 and a port ld leading out of the chamber 9 communicates with the duct 15 feeding the pen l1 in the usual well known manner. 'llhe removable cap l2 is provided to permit the insertion of. new ink blt till

-ber 2in any suitable manner and while we have shown and will now descrlbe one means4 ldd ldll

ebarrel 1 likewise serves to eff'ect a dilution of material 13 whenreplenishment is required. Two or more ports or passages 16 are provided inthe cylinder 8 to permit the fluid contained in chamber 2 to enter the chamber, 9 at the approximate bop thereof and pass down the chamber 9 when the pen is in use, dissolving in its passage a sufficient quantity of the' ink 13 to supply, through the port 14 and duct 15, writing fluid to the pen 11.

As shown, the cap 12 is provided with a chamber 17 with beveledfwalls so that where an ink pencil, such as illustrated at 13, is employed, it may be removed from the chamber 9 or supplied thereto by forcing the -eap 12 over the ink sticky 13 without touching the hands or lingers to the yink stick to be stained thereby. Likewise, the beveled walls of the chamber 17 of cap 12 are grooved, as indicated at 18, to permit the fluidocontained in the chamber 9 to flow into the chamber 17 when the pen is tilted to its inoperative position, such as when normally carried in the pocket. With this arrangement it will be apparent that upon again tilting the pen into its writing position, in addition to the fresh supply of water or other suitable fluid through the ports 16, an initially prepared writing fluid from the chamber 17 is likewise supplied to the pen point. It is obvious that if the pen remains in non-use a long period of time, the solution contained in the chamber 17 is apt to become strong, and in this instance the fresh supply of water or 'similar fluid fr0m chamber 2 of the solution' and tend to maintain the strength of the solution supplied the pen uniform.

The pen, if desired, may be provided with the usual cap 20 for enclosing the pen point when the pen is in non-use.

Many modifications and changes in detail may be made without departing from the spirit andscope of our invention as defined in the claims. For example, andreferrin to Figs. 4 and 5, we show a slight modification wherein we provide means for insuring the writing fluid contained in the nib or feeder, being retained therein when the pen is inverted to its non-use position. In this arrangement the feeder 81 is practically completely 'enclosed by the nib support 6 and is provided with one or more grooves 30 to permit the lluidfrom chamber 2, when the pen is inverted to its writing position, to flow through the grooves 30 to the annular passage 31 which communicates with groove 32 similarly formedin the wall of the nib cylinder portion 7. The'groove 32, however, does not extend to the rear end of the nib but terminates at the port 160, which leads int the interior of the nib which contains t e ink stick or ink solution in the manner hereinbefore set tforth. It will be observed that the groove 32 and the closed in Figs. 4f and 5 is believed to be apparent from the foregoing description. When it is desired to use the pen, the pen is held in its normal writing position, whereby the fluid contained in chamber 2 flows downwardly in grooves 30 to annular passage 3l and is forced upwardly through groove 32 into the port 160 and, consequently, the

-topcof the chamber 9 of the nib 8, flowing past the ink material, dissolving a sufficient quantity thereof to providea writing fluid, and out of the chamber 9 through duct 15, to the pen 11 in the Vusual well known manner.

From the foregoing it will -be observed that we have provided a fountain pen in which, for a long period of time, while it is in use, the only replenishment required is a liquid solution, such as water` which is available at practically all places, and certainly in many instances where a writing fluid is not available. Powdered ink or ink vsticks are now well known in the art and a stick of the size contemplated for use in connection with our invention will supply a writing fluid, when take-n in connection with the liquid supply, an exceedingly long time and the insertion of a new: ink stick is facilitated by the structures herein disclosed. t
