Application filed November 5, 1919.

To all whom it may concern Be it known that I, ALBERT E. Bunnuss,

citizen of the United States, residing at Nor folk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Inkstands, of which the followin is s ecification.

Mj."invei1tion relates to inkstands.

The object of the invention is to provide an inkstand which excludes dust therefrom, to be simple in construction and lessen the spontaneous evaporation of the ink.

Further objects and advantages will be more fully described herein andspecifically pointed out in the claims hereunto annexed recourse being had to the accompanying drawing forming a part of this specification in which Figure 1 is a sectional elevation of the inkstand.

Fig. 2 is a plan of the same.

Fig. 3 is an enlarged view of the pen receiver or ball depressing cylinder, and Fig. I is an elevation, (with a part in section), of the ball inclosing sleeve.

In the drawing like reference numerals indicate similar parts in all the several views.

1 is the ink reservoir provided with a filling plug 2 and a false bottom 3, the main bottom at being common to both the reservoir and the ink well extension 6.

In this manner a large quantity of ink may be put into the reservoir without changing the level in the ink well in accordance with a well known law of hydrostatics.

In very large commercial houses and railway offices the necessity of frequent refilling of the inkstands is eliminated.

5 is an orifice a short distance from the false bottom 3 connecting the reservoir 1 and the inkstand 0r inkwell 6 and is level with the ink surface as shown in Fig. 1.

The upper surface of the extension 6 is provided with a threaded orifice for the reception of the ball sleeve 7 having a corresponding screw thread 7 and a flanged knurled portion 7, as shown.

The lower part of the sleeve is provided with a thinner sleeve extension 8 of hard rubber or other material and at the junction of the said thin part and the upper sleeve member 7 there is provided an annu lar beveled seat 9 conforming to the sphericity of the buoyant ball valve 12.

10 and 11 are holes in the sides and bottom Specification of Letters Patent.

of the sleeve 8, respectively, for the passage of the ink thereto. I

12 is thcball float or valve held in striking alinement with itsseat at 9 by means of thesleeve member 8 and forced against it by the pressure of the'inkand to be dis placed only by the pen, as will be described hereafter. I

13 is the pen receiver and ball depressing sleeve slidably mounted "within the upper DQ113011 of the outer sleeve 7 and is provided with a flange 14.

In Fig. 1 the sleeve 13 is shown raised and in its norinalposition and the ball 12 is upon its seat due to the pressure of the ink and consequently the sleeve bore or orifice is closed. The sleeve 13 is cylindrical upon the outside but the interior surface or bore is cone shaped as indicated by the numeral 15 and is for the purpose of permitting the shoulder of the pen and not the pointentirely to press the ball downward thereby preventing injury to the pen point.

The lower part of the sleeve 13 rests upon the ball 12 and in order to allow the ink to pass freely over it when depressed, notches with resistance therein thus preventing the point of the pen from coming in forcible contact with the ball. 20, shown by dotted lines, indicates the pen and the lower portion of the penholder 21, the former bcin shown in the act of depressing the bal valve 12. f The advantages, of the inkstand are maniest.

In the-first place, the ink loved 6 is constant regardless of that in the reservoir 1.

Secondly, the ball being against its seat at all times, prevents the ingress of dust and prevents the evaporation of the ink. Lastly, the pens are not injured by dipping them in the well,.also its ease of operation and the accessibility of the inclosed parts for clean-.


j in the Well I claim; l. A device of the class descr bed comprismg a reservoir and an extension thereor having their bottoins at different elevations;

orifice connecting means between said reservoir and the extension, a ball valve and an inclosing sleeve in the extension, and a slidebly mounted sleeve Within the first named sleeve adapted to depress said ball.

2. A device of the class described and in combination With an inkstend or Well, 01" a ball valve, an inclosing perforated sleeve for said ball h ving a threaded upper portion and a thinner lower portion and provided with an annular beveled seat for the ball when held thereto by its buoyancy, and a sleeve member slidably' mounted in the first named sleeve adapted to dislodge the ball from its seat. p 7

3. In combination With an inkstand, of a fixed sleeve adapted to extend partly Within the ink and consisting of an upper portion having an annular beveled seat, a bell float or valve therefor adapted to close said sleeve, a thinner lower portion of the sleeve adapted to inclose and guide the ball to its seat and provided With orifices for-the ingress of ink to said lower sleeve, and a. notched sleeve slida-bly mounted Within the first named sleeve and operated by the pen to dislodge said ball to ink the pen.

e. In combination with an inkstand, of an outer sleeve having an annular seat, a ball valve or closer adapted to be guided to the seat hy the sleeve ink orifices therein, a slidably mounted sleeve. \Hithin the first named sleeve adapted to cause the ball to leave its seatxb v the depression of the penand having a tapered or cone shaped interior and notches at its lower end for allowing a flow of ink to said inner sleeve and to the pen.

In testimony whereof i have hereunto affixed my slgnature 1n the presence of tWo witnesses.
