To ALL WHOM IT MAY coNcEeN; Y

Be it known.. that I, SAMUEL DA-RLING, of Bangor, in the county of Penobscot, and State of Maine, have invented certa-in Improvements in Inkstands;` and do hereby 'declare that the following, taken in connection with the drawings which accompenyand form part of this specification, is a. description of myinvention suiiicient to enable those skilled in the art to practise it.

Figure 1 represents an elevation, and

Figure 2 a vertical section of my improved inkstand; and

Figure 3 a plan ofthe follower audits adjusting-screws.

Referring to the accompanying drawings, A represents the lower portion of the stand, formed of Britannia,

.cast iron, or any other suitable material.i B, aremovable portion, fitting tightly therein, and which' I prefer to make of glass or porcelain, and to which is attached a exible and compressiblepouch or sack, C, preferably made of Incliarubber, vulcanized or not, as may be desired; or it maybe made of any other material, provided it be impervious to ink, land 'of apiiexible and yielding character. D is the top or cap-piece, surmounting the whole, and, by means of a groove or otherwise, made to fit closely and snugly upon B; The better way, however, to make this is to form B and D solid, and in one-piece. The pouch may be large enough to occupy, when filled. 4a considerable portion of the space E between the follower F'and the part B. The'follower`F, matic of any suitable material, I prefer to make with a cavity or opening either at its centre or at that portion which lies beneath that part of the sack which, when dist-ended by the ink, hangs farthest down, and it is of such vdiameter as to be moved freely vup or down within the stand. In its edge or periphery I insert several v (say three) pins or screws, G, at equal distances apart-,and each of these passes through a spiral slot, H, out through the stand A, andy-.inning from its base nearly to its top. The pouch' may be secured to the part B in any well-known manner- VI 4have shown it as surrounding with its mouth a tubular projection, I, thereon, to.

which it may be tied by a cord or thread. This .projection and tube need not necessarily be 'Centra-Hysituated, as shown, but may be located at one side. In that portion of the cover which lies immediately above the tube ofthe projection I is the mouth or dipping-cup K, for the insertion of the pen,` this cup tapering downwards in its bore, to prevent the 'pen being dipped to'o far into the ink. In this' cover is another holel or orifice, L,-

.designed for a cork or other stopper. A slightair-outlet is left in this cork. vThe top of B is made slightly con# cave, or dish-shaped, and the lowest extremity of the dipping cup K reaches nearly to but not so as to be in contact with B.

When the follower is to be held in place v,by tightening a screw, one only of the pins G need be tightened for that purpose, and the heads of all the others may be cut olf ush with the outer surface of the stand, so that the operator can take hold ofthe right one only.; and the headless ones may have slots in the ends, for the sake of conveniently removing them when desired. It is not, however, necessary that any of these pins be made to screw, as the follower maybe held in placeequally well by' friction either of the pins against the sides `of the slots, or ofthe follower against the inne'r sides of the sta-nd.

The operation is as follows: The sack being well'tilled with ink,'and so'as to exclude all ain-sufficient additional ink should be poured into the dipping-gauge or cup to rach above the mouth M, and partially 'dll the space'between B and D, so that the lower point of the dipping-gauge may be in the ink. The stand is now1 ready for use.

As the ink becomes diminished by use, a loosening ofthe screws, when screws are used, or the mere turning of' the follower, when it is held by friction only, admits of raising the follower to any degree desired, and there securing it, so that the whole body of the ink shall be held up by it. The degree to lwhich it should be raised should be such 'as always to keep the level of the ink a little above the bottom of the gauge-cup. The great breadth of surface of the ink in the reservoir, compared with that in the gaugecup, requires, however, this adjustf ment tobe but seldom made. This raising of the ink may be continued until nearly all the ink is forced out of the pouch.

No air, it will be perceived, is in the pouch when properly iilled,'nor can anyenter it if it has proper atten tion. And this is'a feature, it is believed, not found in any inkstand now known.

It will also be observed that its principle differs entirely from all that class of stands in which only a small column of ink is raised by a descending follower or plunger. In the present invention the whole body of the ink is raised, and not merely a small portion of it, whilst theink also is always near the top, and not constantly receding from it. l

There maybe more than one tube, if found convenient, for filling or cleaning the stand.

I do not confine myself to any particular form ofthe rubber, or its equivalent, nor to any particular position of it, nor to any of the special means I have shown for expelling the ink therefrom, for it is evident that various forms of pouch, and various locations for'it, and various devices forcompressing it, may be-devised, all of which' would embody my invention, and be no departure from it. y K

The pouch might eren be placed outside the stand, and itmight be compressed by hand, provided any means be furnished to keep it so compressed and at the same time admit no air within it.

Nor do I conne myself to any particular way of connecting the pouch to the tube.

VIt may sometimes belfounddesirable to ll the space E, between the pouch and B, with wooden half rings, made dat, andfremovable at will, butI have made a hole in the follower, to allow it to be raised high enough to pass by and beyond the tube sufficiently to 'pressthe ink out from the sack.

I do not 'claim an inkstand having a iexible ink-reservoir, when in the performance of its functions, the reservoir depends upon the use and occasional admission of atmospheric air Within it; but

1. I claim aninkstand, having an elastic ink-reservoir, C, a dipping-cup, K, and a presser, F, constructed and operating substantially as described. l

v 2. I claim an inkstand, having, in combination, an elastic or iexible ink-reservoir, a pen-dipping cup, and an intermediate ink-chamber, arranged and operating substantially as described.

3. I claim an inkstan'd, having, in combination, an elastic ink-reservoir, a follower, an intermediate inkclxamber, and a penfdipping cup, substantially as described.
