My invention relates to improvementsin foun- The instant invention is designed with the primary object in view of providing in afountain ink Well, supplied by an inverted bottle of ink, for utilizing a capped ink bottle in theV wellas a 'source of ink supply and for opening up the bottle by loosening the cap after the bottle has been placed in inverted position in said Well.

Another object is to provide for accomplishing the above by means of simple form rand inexpensive construction so that the ink Well may be manufactured, together with the ink bottle and cap, at a comparatively low cost. To the accomplishment of the above, and'ancillary objects, presently appearing, a preferred embodiment of my invention has been illustrated Ain the accompanying drawings, set forth in detail 'in the succeeding-description, and defined in the claims appended hereto.

In said drawings:

4 clams. (C1. 12o-:59)

Figure 6 is a View in horizontal section taken on the line 6--6 of Figure 5; and,

Figure 7 is a View in perspective of the closure 45 cap inverted and detached; y

Referring to the drawings by'numerals, the 'type of fountain ink well illustrated, and with which my improvements are especially concerned, comprises a flat bottomed body I which, as shown, is of generally oval form in plan with a substantially cylindrical, open top, ink bottle compartment 2 therein having a pen ller bowl 3 at 4one side thereof With which said compartment 2 communicates. The body I, as shown, is fitted in and seated in a similarly shaped base 4 having an edge Abinder 5.v` A plate 6 on the top I of the filler boWl'3 is provided with'a penrest 8 depending through vsaid top 'I for supporting a pen 9 with the pen pointy IIlspaced'from the bottom of Vsaid bowl. A cap-type cover I I fitted on the body I, overthe ink bottle compartment 2, closes said eompartmenti Y According to thefinstant invention, the bottom l2 of the body I is provided with'an annular, relatively small, bottle holder I3, of sleeve-like form, vupstanding therefrom in theaxis of the ink lbottle compartment 2 and internallyitapered downwardly to said bottom I2. Within the bottle holder I3, said bottom I2 is stepped down to form an annular, raised, internal bottom shoulder I4 'in said holder. A diametrical rib I5 is formed on said bottom I2, inside vsaid holder I3,'and Whi-ch extends from side to side of said'shoulder I4level therewith. A pair of aligned grooves lIISl are formed in said bottom I2, inside said'holder I3, `and which extend radially'thereof upon opposite side'sfof vsaid rib I5 at rightangles thereto. vA pair ofl longitudinal, diametrically opposite, vinternal ribs I1 extend in said holder I3 from the rim thereof tothe shoulder I4, and a pair 0f internal diametrically oppositelongitudinal grooves I8 in 90 angular relation to said ribsIl. i At the bottom of the ink bottle holder I3, an ink discharge port I9 is provided in the side thereof vand which forms an 'ink level port inthe usual manner. ,A pair of` pin-'hole air inlet ports 20 vare 4formed in the side of said holder I3 atthe top of faid port I9 and upon opposite sides of the same `for"'aparticular purposepresently'seen.

VA closure cap 2l is provided for an ink bottle 22 having a sloping top 23' and an externally .threaded neck, 24, .The closure cap 2| is substantially ,frufs'to'fconical' in .'form to conform w'ithfthe internal taper of the inkfbottle'holder circumferential shoulder -25 adapted to t down .wardly ontheshoulder I4. A pair of longitudinal, diametrically.opposite,'ribs 26 on the side of said `closure cap. v2I, t in the longitudinal grooves I8 in the ink bottle holder I3. A pair of longitudinal, diametricallyf opposite, grooves 21 in the side of the closure cap 2I,"in 90 angular relation to the ribs 26, t over the longitudinal ribs I'I in said holder I3. A diametrical top groove 28 in the closure cap 2I .ts over the rib I5 at the bottom of said holder I3, and a pair of aligned, radial, top ribs 29 on said closure cap 2|, in angular relation to the groove 28 and upon opposite sides thereof, fit' in the grooves I6 in said holder I-3. A discharge port 30 in the side of the closure cap 2 I, similar to the discharge port I 9, and adjacent to the top of said cap, is adapted to register with the discharge port I9, and a pair of pin-hole air inlet ports 3l in the side of said closure cap 2|, similar to the pin-hole ports 20, are adapted to register with said ports 20. The closure cap 2| is provided with internal threads 32 extending part-way down the same for screwing said cap onto the neck 24 of the bottle 2I, and with the usual gasket 33.

As best shown in Figure 5, when the ink bottle 22 is placed in the ink bottle holder I3, in inverted position, with the closure cap 2| screwed tight on the neck 24, and the ribs and grooves.2li, 21 of said cap intertted with the grooves I8 and ribs II of said holder, also the groove 28 and ribs 29 of said cap interfitted .with therib I5 and grooves I6 of said holder, the closure cap ZI is interlocked with said holder I3 at the sides and bottom of said holder and said closure cap is also interlocked with said holder I3 against turning therein and with Vthe'ports3ll, 3I- of said cap registered, with the ports I9, 20 of said holder. Now, by unscrewing the ink bottle 22 to raise the neck24 of the same above the threads 32, said neck 24 `is elevated sufficiently so that the rim thereof clears the ports 30, 3I in the closure cap 2|,-.and the ink bottle 22 is thus opened for discharge of ink therefrom through the ports I9, 30 into the compartment 2 and wel-1 3, to the level of thetops of the said ports I9, 3!! while the pinholeA ports 20, 3I provide for admitting air to said cap.2| and neck 24 so that the ink will ow freely from the ink bottle 2|. By merely screwingk the ink bottle 22- tightly into the closure cap 2l, -said bottle maybe closed, at will, as desired, rand for removaland replacement purposes. By varying the height of the rim of the neck 24 fromV the tops of the discharge ports I9, 30, the level of the inkin the compartment 2 and bowl 3 may be varied. Interlocking therclosure cap 2| with the bottom I2 through the ribs I5, 29 and the grooves I6, 25 provides irregular coengaging surfaces on said cap and bottom tending to prevent ink seeping in between said cap and bottom from causing the cap to adhere to the bottom and thereby render removal of the cap dilicult. Y

The foregoing will, it is believed, sui'lce to impart a clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is susceptible .of modification withoutY departing from the inventive concept, and right is herein reserved .to such modicationsas fall within the scope of the l,appended claims.
