IMPROVEMENT 1N INKisTANDs.

1 Specification forming part of Letters Patent No. 147,031, dated February 3, 1874; application filed l April 11, 1873.

V is a top view, and Fig. 5 a transverse section, of

the ink-reservoir supporter. Fig. 6 is a top view of the seat of the rotary cover. Fig. 7 is a transverse section of such seat, the section being through the bayonet-connection projections or hooks. Fig. S is an under-side view, and Fig. 9 a transverse section, of the rotary cover. Fig. 10 is a top View of the combined ink-reservoir and well and the elastic cap of the said reservoir.

In such drawings, the ink-reservoir is shown at A, and the well at B, the two being formed, as represented, in one single piece of glass, and in a suitable mold. In the lower part of the partition or wall a, separating the well from the reservoir, there is a duct or passage, b, which, after the combined ink-well and reservoir is cast or founded and become cool, I make by a lever provided with a tooth or spur. I force the spur or pivot through the wall, which I cast sufficiently thin to enable such to be easily effected. The ink-well is conical or tapering, in manner as shown. In the lower part of the ink-well, and directly opposite the passage b, Iform, at aright angle with the axis of the said passage, an abutment or anti-deector, c, the purpose of which is to prevent the ink,

` when rushing suddenly from the reservoir into the well, from being deflected upward and ,out of the well, as it would be were it to im- 4pinge against the inclined inner surface of the Well. Such an escape of ink is very liable to take place without the anti-deector, but with such it is entirely prevented. The combinedsupporter. An elastic cap or cover, E, made of india-rubber, and in the form as shown, ts into the mouth of the ink-reservoir, and rests on the top of the same. This cover is composed of a flat dome, f, a tubular cork or extension,

i g, and a circular ilange, hf, all beingforined and arranged in manner as shown in the drawings..

In connection with the supporter C and the combined glass reservoir and well, I employ a rotary cover, G, and a domed seat-plate, F, the latter serving as a cap for the ink-well, and being provided with an opening, h', to constitute a mouth for the said well. The dome i of the plate F has a curved slot, k, and a key-hole, l,

formed through it, and arranged in manner as shown, and it also has pivoted to it, and arranged so as to extend across the slot k, a tongue or depressor, H, which, when the seatplate F is in place in the supporter C, rests directly ou the top of the elastic cover E; The supporter C has locking-flanges m n o arranged around within it, over the ink-reservoir rest, such an ges having spaces p q between them. Furthermore, a spring, r, arranged with respect to their flanges in manner as shown, is for a purpose to be hereinafter explained. The seatplate F has three projections, s t t, extending down from it, two of them, t t, being hooked to operate with the flanges m o in connecting the said seat-plate F to the supporter C. By hooking one hook, t, under the flange m, the other may be moved down through the space q. By next turning the seat-plate a little on the supporter C, the projection s will be moved by and beyond the spring r, which, as soon as the projection may have passed its free end, will spring inward, so as, with the projection s, to prevent the seat-plate from being turned in a reverse direction. Thus it will be seen that the spring 1' and the projection s, combined with' the above described bayonet connec tion 7 of the seat-plate and supporter, serve to lock the seat-plate to the supporter. By inserting a key, u, (see Fig. 11,) in the key-hole of the seat-plate and turning such key, the

spring may be forced back so as to allow the seat-plate to be turned back far enough to admit of it being disconnected from the supporter. The rotary cover G, formed as shown, is pivoted to the seat-plate, the pivot being seen at o. Such cover is provided with a cam or inclined projection, w, to extend through the curved slot of the dome of the seat-plate, and against the movable tongue or depression H.

On turning the cover Gr around so as to uncover the mouth of the ink-Well, the cam Will be moved so as to force downward the depression upon .the elastic dome of the cover E. Such will press down the dome, and, as a consequence, the air underneath it and in the ink:- reservoir will be compressed, and will force ink out of the reservoir into the Well. On moving the cap so as to cover the mouth of the ink-Well, the elastic dome of the cover E will expand, so as to cause the compression of the air to cease and the ink in the Well to be driven back into the reservoir. Thus, by the movements of the cover, the ink may be forced into the ink-Well from the reservoir and be drawn back therein, so as to be preserved from loss by evaporation during such times as the inkstand may not be in use.

. This inkstand is designed for a school-desk, but may be lotherwise used.

I claim as my invention the following:

1. The ink-reservoir A and the conical Well B, arranged, connected, and provided with the anti-deiiector c, disposed in the Well, and with respect to the communicating duct b, as set forth.

2. The combined glass ink-reservoir A and Well B, cast in one piece, and having their duct of communication, b, subsequently made by breaking through the Wall of separation of the Well and reservoir, as stated.

3. The ink-reservoir supporter C and the cover-seat F, constructed, arranged, and provided With the bayonet-eonnection, Jche locking-stud s, and spring fr, and key-hole l, all substantially as explained and represented.

4. The rotary cover G and its cam fw, combined and arranged with the cover-seat F and its slot 7c, and with the depressor H, pivoted to the seat, all being for use with the elastic cap E of the ink-reservoir, in manner as described and represented.

5. The supporter C, the cover-seat F, the rotary cover G, the cam w, the depressor H, the elastic cap E, and the ink-Well B, and reservoir A, arranged, constructed, and applied together substantially as described.

6. The ink-reservoir elastic cap E, made as described, viz., of the lat dome, its circumscribing ange, and the tubular cork, arranged as specified, whereby it is rendered applicable to an ink-reservoir, as set forth.
