To @ZZ whom, it may concern:

Be it known that I, SUMNER P. BARKER, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State 5 of Indiana, have invented'a new and useful `Improvement in Inkstands, of which the fol- .lowing is a specification.

'Ihe objects of my'inven-tion are,-f`1rst, to

prevent evaporation and spilling of `ink and,

Vithough normally securely closed by the au tomatic action of a valve, stands practically open at all times, admitting thepen into the ink with the same freedom as does the ordinary open inkstand. In securing these ends my invention contemplates an inkstand having a hollow or tubular stopper, the lowerend being normally closed by a Valve, which` isi thrust against it by a spring, and other details' making-up the device as a whole, as herein#` after more minutely described and illustrated' l by the accompanyingdrawings, in which-.-

Figure l is view in central vertical section 'of the inkstand with stopper closed bythe valve. Fig. 2 is a view in central vertical section of the inkstaud with the valve opened by pressure upon the pen and the pen-point immersed in the ink. f Fig. 3 is a perspective View of the stoppe-1' encircled by a rubber band, which serves as a packing betweenA the stopper and the neck of the inkstand, .t Fig. 4 is a view of the valve which closes the stopper. y The manner of construction herein described is deemed .most practical, although various changes may be made in f orm aud manner of construction wit-hout departing' from or evading the principlesuset forth in the claims. l

Referring to thedrawings, Iin which the ref-- erence characters'denote corresponding'and llike parts in all views, `A .designates an inkstand with wide neck, preferably about-one inch wide. v.

The letter B indicates the stopper, whichy y may be made in two parts l and B'and united by some adhesive and insoluble substance. The parts may be made of vglass or other suitable material. Part B is a thick hollow rimr suitable to be gripped by the fingers and a. thin shell or tube dependingr from its inner ent, is-

edge and tapering to an opening about three-fV eighths of an inchdn diameter and havinga groove adapted to contain the rubber rim E,

which serves afs-packing betweenthe stopper l the rim of part B, the small end corresponding in size with the opening in the lower end 6o of the stopper, and depending into the central cavity ,of the stopper forms a recess betweenit and the outer walls of the stopper.

The' valve C, which closes the end of the stopper B, may be made of thin sheet metal V' and'is vprovided with an open framework or guiding-arms adapted to insure its pro erad- Vjustinent as4 it closes,v being4 normally eld to itsplac by the spring D, one end of which against 'the bottom of the inkstand or bere- 'ltained in-a groove or recess in its sides, or it may be applied in any other suitable mannen A'small disk of" rubber or leather' may be supper-ts the valve, while the other may thrust 7c placdupou the .valveand may be renewed at pleasure. 1

It will be observed that as the pen is introduced into the ink the valve is depressed by pressure upon the pen and that as the pen is 'removed t-he'valve rises and closes the Iink- 8e standr 'and that when the inkstand is over turned any ink that the stopper may-contain;

will be retained in the recess around the,

opening."

Having I claim,rand desire to secure by Letters Eat:

l. An in kst'and having in combination-there# thus described my'i'nve'n'tion, what lwith ahollow stopper adapted to securely opening through which the pen may bethrust, a short tube dependingfrotn thetop of the stopper around the opening forming a recess between the tube and the outer walls of vthe-j stopper,` a valve thrusting against the lower .95

end-of the stopperV having a guiding' frame workadapteto insure its proper'adjuy .ment, Vand a` lspring located within the ink'stan'd adapted to hold the valve'against thestop'per. `1

pressure allsubstantially as 4close the saine and provided' with a cent'ralfe. x,

practcalfsze, a short funnel-shaped tube depending from the top into the central cavityy securely close the opening in the lower'end of the stopper and having an open framework or guiding-arms embracing the tapering end of theshopperzmd a spiral spring normally retaining the valve/against the stopper,

one end of which embraces the framework of the valve while the other is engaged by the groove in thewalls of the inkstand, substan- 'oi-nlly as described and for the purposes ser forth.
