INKSTAN D.

Specification of Letters Patent.

Patented @ct. l, 1918.

Original application filed January 3, 1913, Serial N 0. 739,946. Divided and this application filed September 20, 1913. Serial No. 790,836.

T0 04% whom it may concern:

Be it known that I, FRANK M. ASHLEY, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Inkstands, 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, such as described in my copending application for inkstands filed Jan. 3, 1913, Ser. No. 7 39,946, of which the present application is a division.

In the above mentioned original application two embodiments of the invention were shown, certain of the claims being drawn to broadly cover both embodiments and certain other of the claims, specifically directed to the form in which the ink dip is located in the base. The present application is more particularly directed to the form in which the ink dip is located in the cover, and among its advantages may be mentioned the simple formation of the base and the construction wherein all possibility of overflow through the action of the plunger is avoided.

In the drawing illustrating the present embodiment of my invention,

Figure 1 is a sectional elevation, and Fig. 2 is a plan view of an inkstand embodying my invention.

Referring in detail to the drawing, the base 1 of the inkstand is of broad, 10W construction, and has the reservoir 2 formed therein. A cover 3, made of hard rubber or any other suitable material, is provided for the base, and has a cylindrical projectlon 4. depending therefrom substantially in the center thereof. The cover is formed with a dip cup 5 which extends through the projection to communicate with the reservoir. The

{cylindrical surface of the projection 4 is threaded to engage an interiorly threaded plunger 6, which is designed to fit loosely in the reservoir. When the reservoir and plunger are circular, which is the preferred form, I form a flat portion 7 on the inner side of the wall of the former and provide a corresponding flat portion on the outer periphery of the latter, so that there can be no relative rotary movement. Thus, by turning the cover in the proper direction, the plunger will descend deeper into the reservoir until it touches the bottom thereof, or vice versa. It will thus be seen that, when the level of the ink in the dip cup is too low, all that is necessary is to turn the cover and the de scending plunger displacing a portion of the ink raises the level thereof to the required height in the dip cup. In this construction there is no possibility of the ink overflowing even though the reservoir may be full and the plunger depressed to the bottom, for the reason that the displaced ink may flow around and over the plunger and fill the space left vacant thereby. The dip cup 5 is preferably provided with a conical portion 9 the top edge of which is preferably 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. The upper face of the plunger is beveled to form a central conical depression 8 to fit the conical portion of the dip cup. Thus, the plunger can be adjusted so as to abut the bottom of the cover.

It will thus be seen that I have provided simple and inexpensive means whereby the level of the ink can be maintained at any desired height in the dip cup of a low type of inkstand having a comparatively shallow reservoir. By forming the dip opening in the cover assurance is had that the ink will not overflow no matter how far down the plunger is adjusted, since the opening terminates at a point above the top of the reser voir and the ink is free to flow about the plunger. The reservoir can easily be cleaned when necessary, none of the parts being fastened in any manner thereto. The three parts which compose the entire stand are simple, inexpensive, and easy to manufacture.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

An inkstand comprising a base portion having a reservoir, a cover resting on said base portion and having a depending portion provided with a dip, the top of which Signed at New York in the county of New is located below the top of said base port-ion, York and State of New York this 13th day and a displacing element connected to said of September, A.
