INKSTAND.

Milli-1m Specification of Letters Patent.

Application filed January 3, 1913.

To all whom it may concern:

Be it known that I, FRANK M. ASHLEY, a citizen of the United States, and a resident of New York city, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in lnkstands, of which the following is a specification.

This invention relates to inkstands, particularly to the low type of inkstand having a restricted opening forming a dip chamber.

It is found in inkstands of this character that the ink often gets low in the reservoir and although there may still be a considerable quantity of ink therein, the level of the ink in the dip opening is too low to properly ink the pen. Moreover, very often it is desirable to change the level of the ink in the dip opening in order to accommodate pen points of different lengths.

The principal object of this invention is to provide simple and inexpensive means whereby the level of the ink in the dip opening may be varied at will.

A further object is to provide in a low type of stand in which the reservoir is located entirely in the base, simple means directly engaged by the cover whereby the ink is maintained. at the desired level in the dip opening.

A still further object is to so dispose the adjusting means within the reservoir as to preclude the possibility of the accidental overflow of the ink through the dip opening.

in the drawing illustrating the preferred embodiments of this invention, Figure 1 is a sectional elevation and Fig. 2 is a plan of an inkstand embodying my invention. Fig. 3 is a detail of the plunger. Fig. 4: is a sectional ele ation and Fig. dis a plan view of a modified form.

Referring to the embodiment of the invention as illustrated in Figs. 1, 2 and 3, the base 1 of the stand is of low, broad construction and has the reservoir 2 formed therein. A dip opening 8 extends to one side of the reservoir preferably at an angle thereto, so as to facilitate the-insertion of the pen. The ed of the base adjacent to the dip opening is beveled off to form an inclined face 4, to further facilitate the insertion of the pen at an angle, so that the stand may be inserted in a pigeon hole or rack upon a desk and still be readily accessible.

I will now describe the means whereby the level of the ink in the dip opening 3 is adjusted to the desired height to suit the con- Patented (lot. 2 1%, 1911.6. Serial No. 739,946.

venience of the person using the stand. The cover 5, which is preferably circular in form, has extending into the reservoir a central, cylindrical projection 6 which is preferably threaded to engage an interiorly threaded thimble 7 attached to a plunger 8 which fits the interior of the vertical wall of the reservoir. A. guiding lug 9 preferably extends outward from the periphery of the plunger into the vertical passage 10 formed between the dip opening 3 and the reservoir. This lug guides the plunger in its vertical movement and prevents rotary movement thereof. lVhen it is desired to raise the level of the ink in the dip opening, the cover 5 is rotated so as to depress the plunger 8 and displace a portion of the liquid and thus raisethe same in said dip opening. A channel 11 is preferably formed at the top of the plunger, so as to reduce the peripheral diameter thereof at that point and prevent the capillary action between the periphery of the plunger and the interior of the reservoir from raising the ink to the top of the base. The plunger may, if desired, be cut away adjacent to the dip opening 3, so as to form an incline 12 which permits the pen to be inserted at a greater angle if it is found necessary to do so. A pen rack 13 may if desired be formed on the top of the base at each end thereof.

In the modified construction illustrated in Figs. 45 and 5, the base 20 has the reservoir 21 formed therein and the cover 22 has a central dip opening 23 provided with a downwardly projecting cylindrical portion 24. The latter is exteriorly threaded to engage a threaded bushing 25 attached in the interior of the bore formed in the plunger 26. The latter loosely fits within the reservoir and has a flattened portion 27 at one side thereof to engage a similarly flattened portion 28 formed on the interior of the upstanding wall of the reservoir. These flattened portions prevent the plunger from rotating while permitting the same to move vertically within the reservoir. When the cover 22 is rotated in the proper direction, the plunger 26 is lowered and the ink thus displaced rises in the interior of the dip opening 23 to the proper desired level. In this construction, the plunger may be lowered clear to the bottom irrespective of the quantity of the ink in the reservoir without causing the ink to overflow through the dip opening, for the reason that on account of the loose fit of the plunger 1n the lnterior of the reservoir the ink can flow upward over the plunger and whenthe latter is completely depressed, the ink may be entirely displaced to fill the space above the plunger, As in the preferred construction, the plunger may be provided with the channel 29 formed peripherally therein adj acent to the top of the same and the materials for the various parts may also correspond. The upper'face of the plunger is preferably beveled off to form a central conical depression 30 to correspond with the outer contour of the dip opening of the cover. The conical portion 31 of the dip opening preferably terminates slightly below the top of the reservoir, so that when the ink is raised to the top of this conical portion, it will still be at .a safe level and will not overflow. In practice, the ink should preferably not be raised beyond this conical portion.

In both of the forms above described, the base is formed preferably of glass while the cover may be of hard rubber or similar molded substance. The plunger is preferably formed of some non absorbent substance as earthen ware, hard rubber, light non-corrosive metal or the like, whereas the thimble or bushing is preferably formed of noncorrosive metal and may be cemented in any suitable way within a central bore in the plunger.

It will thus be seen that I have provided a simple and inexpensive means whereby the level of the ink can be maintained at any desired height in the dip opening of a low type of stand having a comparatively shallow reservoir. Vith the use of the'means herein described, the level of the ink can be maintained at the proper height in the dip opening although it has fallen in the reservoir to a level at which a pen cannot be properly inked. The parts are simple, inexpensive and easy to manufacture.

Having thus described my invention, I claim as new:

1. An inkstand comprising a base having a reservoir therein and a dip opening extending therefrom, a cover for the reservoir having a threaded central projection extending into the reservoir, a plunger having a threaded bore engaging said projection, and a peripheral projection engaging the wall of the dip opening to prevent rotative movement of the plunger, the latter being raised and lowered by the rotary movement of the cover to adjust the level of the ink within the dip opening.

2. An inkstand comprising a base having a reservoir therein, a cover for the base having a central threaded projection extending within the reservoir, a plunger having a central'bore engaging said projection and a peripheral channel adjacent to the top thereof,

to prevent the overflow of the ink due to capillary attraction, means for preventing the rotative movement-of the plunger, there being a dip opening communicating with the reservoir in which opening the level of the ink is adjusted by the movement of the plunger.

3. An inkstand comprising a base having a reservoir therein, a cover for the base having a central threaded projection extending within the reservoir, a plunger having a centralbore engaging said projection, means for preventing the rotative movement of the plunger, there being a dip opening communicating with the reservoir in which opening the level of the ink is adjusted by the movement of the plunger, said plunger being angularly cut away adjacent to the dip opening to permit of the insertion of a pen to the bottom of the dip.

4. An inkstand comprising a base having a reservoir therein and a dip opening extending therefrom, a cover for the reservoir having a threaded central projection extending into the reservoir, a piunger having a threaded bore engaging said projection, and a peripheral projection engaging the wall of the dip opening to prevent rotative movement of the plunger, the latter being raised and lowered by the rotary movement of the cover to adjust the level of the ink within the dip opening, said plunger being angularly cut away under the guiding projection to permit of the insertion of a pen to the bottom of the dip.

5. An inkstand comprising a low base hav ing a wide bevel across one upper edge, a reservoir formed in said base offset from said bevel, an ink dip, the opening of which is included in the beveled portion so as to allow the insertion of a pen at an angle, said dip extending to the level of the bottom of the reservoir, there being open communication between the dip and the reservoir for the entire height of said dip, a cover for the reservoir having a threaded projection depending into said reservoir, a plunger loosely fitting within the reservoir, said plunger having a. central threaded opening rotatably engaging said projection, said plunger being raised and lowered by the rotary movement of the cover to adjust the level of the ink within the dip, there being means for preventing rotary movement of the plunger.
