IMPROVEMENT IN INKSTANDS.

'J'.'he Schedule :cibi-red to nfhese Letten :Patenty and making part of the lame.

To all persons to whom, these presents shall come:

the cover, as raised; and v Figure 3, a. longitudinal section of an inkstand con? structed in accordance with my invention, this latter section being taken through, the dipping-cup-and its veut-hole. I

Fgure4 is on under side view ofl the fountain or upper portion of the inkstaud.

Figure 5 is a top view of the lower portion of said stand, and

Figure 6 is a longitudinal section, taken when the ink is low and the ink-fountain has been turned around about one hundred and eighty degrees fromcess in the bottom of the reservoir-located under Athe dipping-cup, all as hereinafter more fully set forth.

In carrying out my invention I construct the bodyportion of my inkstaud in two parts, as follows:

In the drawingv A denotes the upper, and B, the lower portion of the iukstand, each portion being of a frusto-conical (or other proper) shape, the plane of the bottom -of part` A and the plane of the` top of part B being, when thc. parts are in place fo'r use, equally inclined to the horizon. y

For the purpose of hiding the joint between thel said parts, a. rimv or bead, s, may be formed around either of the said upper or lower portions.

The part A is made hollow, or is chambered, so as constitute a 'fountain or reservoir, C, for theink, such fountain increasing in depth from its front to its rear part, as seen in fig. 3, audbeiug provided with a bottomless pen-passage or dipping-cup, al, leading upward from the same. This dipping-cup tapers downward, as shown, and the opening at its lower part is made less iu diameter than a peu, so that, whilst the tip or nib of the pen may project below it, yet the thicker part of the pen will positively arrest or limit its downward movement.

A. cavity or recess, c, is made in a nipple or projection, b, which extends downward from the lower face of the part A, as shown in' figs. 3 and 4. This cavity or chamber is located directly underneath the dippingcup, which is of a hollow frnsto-conical shape, and projects downward from the top of the reservoir into which it opens, as seen.

The object of making this chamber-c directly below the pen or dipping-cup u, iu connection with the small diameter given to the opening at the bottom lof such cup, is to prevent injury' to the point or nib of the pen while being thrust into the cup, aswell as to receive any sediment which maybe deposited or thrown down from the ink.

D is, another cylindrical projection or pin, projecting axially downward from the lower face of the fountain or upper port-ion A,and entering a hole or socket, 0, formed through the part B', as seen -in fig. 5.

The said pin serves to'conuect the two portions A and B, and at the same time to allow either of the said part-s to be freely rotated.

, In the upper surface ofthe said part B an annular' groove or channel is formed, such being for the reception of the 'project-ieu b, containing the sedimentchamber c, hereiubefore mentioned, and for allowing' such projection to be moved throughout such groove during an entire revolution ofthe part Aon the part B.

e is a vent-hole, which opens out of theupper part vof the dipping-cup, and communicates with the interior ofthe ink fountain.

rIhe object of this vent-hole is two-fold: First, vto prevent any expansion of the air in the fountai from causing au overflow of ink; and

Second, to allow the air toescape from the fountain while the latter is being lled with ink.

For the purpose ot'. preventing as far as possible any evaporation ofthe ink contained within the fountain,

and to preclude the admission of dust or other foreign matter intothe dipping or pen-cup, I provide such cup with a self-adjusting and self-closing valve or cover, G, which I suspend from the central part of a.l

curved wire or bail, H, the twoextremities of such bail being jointed or pivoted to opposite sides of the part A, as shown in iig. l.

This valve 01 cover should be so hinged or jointed to the bail that, whenever the hand of a person, after having'eifected the elevation of the bail so as to vraise the cover olf the mout-h of the vinkstand, may have been withdrawn from the arm I of the bail, the gravitating power of the bail, and its arm and the cover.I

shall cause them to descend and the cover to close the said mouth. rllhe lever or arm I is soldered or fastened to the hail H, near its central part, and extends npward therefrom, as seen in g. 1. This arm or lever should he of such form and so arranged that it may be conveniently and readily m'et by the hand of a person while in the act of bengmoved toward the inkstand for the purpose of inserting a pen therein; the pressnrc of the hand against the arm serving, under such circumstances, to raise the bail and its cover so as to open 'the meut-h of the -inkstand for the introduction of the pen therein. During the act of withdrawing 4the pen and hand from the inkstand, the bail and' cover will descend so to carry the cover on and cause it to close the month. v

When the inkstand is to be charged with ink, the

. fountain or part A is to be .turned until the top snrface thereof shall stand in a horizontal plane. The ink is next to be poured into the fountain until it 4shall become full enough which will be indicated by its standing at the desired height in the dipping-cup.

. inkstand is not only simple in construction, and capable of being readily charged with ink, but such ink can easily be maintained at the desired height in the dipping-cup, notwithstanding the quantity in thereservoir may be steadily diminishing, thus insnrng that the pen shall always take up a proper supply, but never an over suppl-y, while at the same time the ink in the reservoir is most eecinally protectedfrom dust or other foreign matters. Y

I do not claim an inkstand made with its ink-holder and its base applied together with' inclined surfaces and a pivot at the junction nor do I claim thearrangement and combination of a bow-lever with a cover hinged directly to the pen part, ring, or cap of .an inkstand, the same being as represented in the United States Patent No. 13,515 but What I claimlas my improvement or invention is as follows:

1. An inkstand, having a reservoir arranged to be rotated upon its bed or stand, and having a dippingvcup on one side of' its center of rotation, when the ink is caused to be at the proper height in the dipping-cup by revolving the reservoir, substantially as described.

2. An inkstand, having a dipping-eu p, the lower' part of which is smaller'than a pen, and having also an ink-containing cavity or recess in the bottom of theoreservoir, lunder the' dipping-cup, substantially as f, and for the purpose described.
