INVENTDRS iii) Patented Mar. 7, 1939 UNITED STATES INK WELL Leon Hehl Ashmore, Collingswood, and George Trotman, Haddoniield, N. J., assignors to The Esterbrook Steel Pen Manufacturing Co., Camden, N. J., a corporation of New Jersey Application September 30, 1937, Serial No. 166,634

16 Claims.

Our invention relates to inkwells, and cornprises certain improvements in that type of inkwell or ink-stand in which a bottle constituting a reservoir for the supply of ink is disposed in an inverted position within a shell or casing constituting the inkwell proper, and which may be of ornamental character. Our improved inkwell structure includes an externally arranged penreceiving dipping well, and the reservoir or inkcontaining ybottle is combined with feeding or supply means of a barometric type for maintaining a proper quantity of inkin the pen-receiving dipping well.

One object of our invention is to provide a type j of inkwell or ink-stand that may serve as a desk set, with a diagonally arranged and externally disposed dipping well arranged to supply the necessary amount of ink to a pen when dipped therein, the dipping well being of such character that the pen may be maintained therein when not in use to serve as means for sealing the same to prevent undue evaporation of the ink.

A further object of our invention is to provide a simple and eicient ink feeding device which may be carried by the ink bottle reservoir and which, when the latter is in an inverted position within the inkwell casing, will serve to maintain ,a supply of ink in the bottom of the inkwell for delivery to the connected pen-receiving dipping well to keep a supply of ink in the same at the desired level.

And a further object of our invention is to provide the bottom of the inkwell with a central recess and a shelf or floor surrounding the same upon which the feeding device may rest, with a narrow channel axially arranged below such recess and communicating with the external penreceiving dipping well.

Other objects and advantages of our invention will be pointed out hereinafter; reference being Vhad to the accompanying drawing, in which:

Figure 1 is a sectional elevation on the line I'-I, Fig. 2, of an inkwell or ink-stand, showing one form or embodiment of our invention.

Fig. 2 is a front elevation of the same; showing the exterally arranged dipping well to receive the pen.

Fig. 3 is a sectional plan view of the inkwell on the line III-III, Fig. 1.

Fig. 4 is a plan View of the feeding device carried by the inverted ink-containing bottle when in the position of use.

` Fig. 5 is a View of the under side of the feeding device.

Fig. 6 is a perspective View of the feeding device on a slightly larger scale, detached from the reservoir bottle, and

Fig. 7 is a similar perspective view of the under side ofthe feeding device.

Referring to the drawing, the shell or container (Cl. 1Z0-59) of the inkwell or ink-stand forming the subject of our invention is indicated at l, and it comprises a hollow body portion provided with a removable cap or cover 2 and having an integral base or bottom 3, providing a iioor 3a. Centrally of the base We provide a recess 3b, and axially of this recess a central channel 3 is formed which leads to an externally accessible dipping well. At the front of the shell or container constituting the ink well proper, we provide a projecting portion 4, integral with such shell, and this external portion is provided with an inclined bore or recess 5 whose lower end reaches to and communicates with the channel 3c in the base of the shell or container. in the projecting portion l forms a pen-receiving dipping well, and its upper portion or mouth may be outwardly flared to provide a suitable seat to receive the end of a pen holder.

A bottle 9, containing ink and forming a supply reservoir, is mounted within the shell or casing l in an inverted position. This bottle carries a cork or plug of special type, indicated at Ill, which forms a most important feature of our invention; such cork or plug tting tightly in the neck of the ink bottle with the aid of a sleeve or gasket Il of resilient material and resting n the oor El2L of the shell l of the inkwell when in the position of use. Within this cork or plug,

The bore or recess a plurality of passages are formed; that indicated at I2 serving for the passage of ink to maintain a supply in the bottom of the shell or container constituting the inkwell proper for delivery to the external pen dipping well via the channel 3c, and that indicated at I3, which is The larger passage I3 terminates ing the recess 3o in the bottom of the shell formf fing the inkwell proper, and may be hollowed out on its under side as indicated at |45, to increase the ink-receiving space and avoid trapping. The flange may be provided with a tubular projection Mb depending from its under surface and forming a continuation of and lengthening of the passage l2 with respect to the lower end of the passage I3. The flange I4 is provided with an opening HC, which may be circular and extends over the lower opening leading to the passage I3, to permit free access of air to such pasage for delivery to the ink in the reservoir in the form of bubbles as the ink is consumed; the presence of such opening in the relation indicated also serving to raise the level of ink in the bottom of the shell or container forming the inkwell proper.

The shell or casing providing the inkwell is closed by a removable cap 2, which is preferably furnished with an aperture 2a to Vent air when the cap is applied after a bottle containing ink has been placed in the shell. If not vented, the application of the cap would tend to compress the air within the shell which, acting upon the ink in the bottom of the same, would cause it to rise in the dipping well and upset the equilibrium of pressures inside and outside the inkwell and the bottle constituting the ink reservoir. In addition, such opening prevents the expansion or contraction of air within the shell or container I, due to temperature changes, from varying the level of ink within the container and/or the dipping well.

The cork I0 should make a tight t within the neck of the bottle, and the edge of the neck may be in contact with the flange I 4; the upper surface of the latter coinciding with the opening at the lower end of the passage I3, which determines the height to which the'ink will rise within the bottom of the inkwell and the external pen-receiving dipping well.

The channel 3 in the lower part of the inkvvell supplies the ink to the external pen-receiving dipping well and by reason of its restricted area greatly lessens the amount of sediment that would otherwise collect in the bottom of the well. In addition, the agitation of the ink as it flows from the reservoir keeps any sediment stirred up so as to pass with the ink flowing to the dipping well where it Will be consumed in the ordinary course of using the ink. This channel is preferably inclined from the back of recess 3b to the bottom of the external dipping well.

All parts of the structure are accessible for cleaning, and when a fresh supply of ink is to be placed in the reservoir bottle the cork, after removal to permit lling the bottle, is preferably cleansed by running water through the passages I2 and I3.

The shell or casing is preferably formed in one piece, and it may be of any suitable material. It may be molded of synthetic resins, or of glass, transparent, or opaque, and it may be of any color. The cap is of such a size that the ink bottle will project above the upper edge of the shell or container when it is removed, to facilitate insertion and removal of such ink-containing bottle.

The cork may be of molded material, with the passages I2 and I3 drilled or otherwise formed therein, and by preference the passage I2 through which the ink feeds to the lower part of the inkwell may be slightly less in diameter than the orifice I3a opening from the passage I3.

While we have described a specic embodiment of our invention, it will be understood that modications may be made therein; all of which are believed to be within the scope of the appended claims.
