in which` thezfinlrnis forced upinto a cup l or basin, and `from which itis again per-` mitted to sink when thejinkstand isnotin use Such inkstandsare liable to theolojec-` tions that they are complex in their opera-` i tion; thatthey require the joints tobe made "and :kept air-tight, thereby rendering the a ."inkstand useless "when they Abecomeworn, .land, in thoselnown `asjthe fountain ink.-

stand, the expansionofwthe air within, by

" 1 an increase oftemperature, causes the ink n to overflow, to the ingury, `1t may be, of:

papcrs,wbooks,furniture1&c. To produce an `inkstand that shall not be liable to the above objections, andthatshall be simple, durableand; efficient inits opera tion, is `the obj ect of `To `enable others skilled in wart, to `make and use my invention,I will proceed `to. `describe its construction andl operation.

\ a is thebody of thefinkstand, `from the rise the cyliniiA is a plunger,from which descends a corresponding series of cylinders, cl, d', al, the

`relative size of theV cylinders being such, thatoneseries shall pass within the spaces between theother series, as seen in Fig. 1.

Bis a `barrel attached to the plunger A,

and has a screw out upon it, which works ina female,`in the cap or cover C, of the inkstand. `This cover, which is notrequired to ttwithan air-tight joint, is furnished Vwith a screw plug L, which closes a hole,

through which the inkstand may be cleansed or'filled. The inner base ring, or cylinder,

, incloses a well c, which is nearly filled by" the piston c, in the center of the plunger A.

The piston o and thebarrel B, are perforated by a small hole, m, which opens a passage fromthe well 7c to the dipping cup i Operation: Ink being poured into the stand, toa level with the topof the cylinders or thereabout, the plunger A is depressed, and the liquid in the well le, being displaced by the piston c, and prevented from flowing outward by the air between the rings d, cl, is forced up the passagem, into the dipping cup f, Where itis retained until the plunger is raised, when the ink descends a `ain into the well lc.

W'hat claim as my invention, and desire to secure by Letters Patent, is

` The wellc, and the cylinders in combination with the piston c, Vand the'cylinders cl, d, al, for the purpose of raising and sustaining i the ink above its level in the inkstand, without the necessity of using the tightgpacked joints, heretofore required.I i f HENRY WHITNEY, JR.V `Vlitnesses: Y r y J.
