UNITED STATES Parent tries,

INKSTAND.

SPECIFICATION forming part of Letters Patent No. 366,206, dated July 12, 1887.

9 Application filed May 26, 1887.

To all whom it may concern:

Be it known that I, SAMUEL DARLING, a

citizen of the United States,-residing at Provideuce, in the State of Rhode Island, have invented a new and useful Improvementin Inkstands, of which the following is a specificatiou.

My invention relates especially to that class of inkstands which are provided with an elastic ink-fountain, and the object of my invention is to simplify the construction of such inkstands and to adapt the same for being carried in the pocket; and it consists in making the top and bottom portions of the fountaiucase in separate parts, which are connected by means of screw-threads, whereby upon revolving one of the said parts upon the other the vertical height of the chamber which holds the ink-fountain will be either increased or diminished, thereby operating upon the inkfountain to cause the increase or diminution of the ink-supply in the dip-cup, as desired; and in an inkstaud having an elastic ink-fountain, a dip-cup or dipping-aperture, a case for holding the fountain, the said case having a screw-thread upon its inner surface, and a bottom plate or follower provided at its periphery with a screw-thread fitting the inner screw-thread of the case and adapted by rotary movement to change the vertical height of the chamber for the inlrfountain, and thus control the ink supply in the dip cup or aperture; and also in providing the closing screwcap of the inkstand with a pivoted stopper, whereby the rubber packing will be prevented from injurious wear or abrasion and a perfectlytight joint will be obtained.

Figure 1 is a vertical section of myimproved inkstand. Fig. 2 is an under view of the bottom plate or follower.

In the accompanying drawings, A represents the top and side portion of the case, which is provided with an interior screw-thread, a; and B the bottom plate or follower, provided atits periphery with the screw-thread b, which fits the screw-thread a of the upper portion of the case. The bottom plate or follower, B, is provided with a central opening, a, which is adapted to receive the bulging bottom portion of the ink-fountain (l, and with the opposite Serial No. 239,497. (No model.)

lugs (Z (Z, by means of which the proper rota tion of the bottom plate, B, is effected.

The ink-fountain O'is made of india-rubber and provided with a neck, 6, by means of which it is to be secured to the portion A of the case. The neck 0 of the ink-fountain passes upward through the central opening, f, in the top of the case, and is secured therein by means of the forcible insertion of the stem 9 of the dipcup D, which serves to press the elastic neck of the fountain firmly against the wall of the opening f. The upwardly-projecting neck or flange h, which surrounds the opening f, is provided with an external screw-thread, i, which is adapted to receive theinterior screwthread, j, of the closing-cap E; and at the upper interior portion of the cap E is pivoted the stopper G, which serves to form a tight joint at the upper edge or surface of the dip-cup, to prevent leakage.

The holdingcase 7c of the stopper is loosely secured to'the lower side of the top of the cap E by means of the screw m, which thus forms a swivel-connection between the case It and the cap, whereby the stopper can be rotated upon the pivot-screw m, and also have a slight rocking movement, so that the rubber packingdisk n, held in the case k of the stopper, can readily adjust itself to a proper scat upon the edge of the cavity 0 of the dip-cup when the cap E is being screwed upon the neck or flange h to close the inkstand, thus preventing the inkfrom leaking from the same into the pocket in which it is carried. The top of the cap E is preferably rounded upward at its central portion, 12, to form a spherically-concave seat for the spherical protuberance (1 upon the up per surface of the holding-case 7c of the stopper, which is thus socketed in the cap E,

The cavity 0 in the dip-cup to receive the ink is slightly tapering, and at its lower end is placed the removable pen gage T, which serves to limit the downward movement of the pen when dipping for the ink, the opening 8 at the lower side of the pen-gage being made ofless diameter than the width of thewritingpen.

When filling the fountain with ink, the pen gage can be removed upward from the cavity 0 The upward by means of ahook or otherwise.

2 aeezoe movement of the bottom plate or follower, B, by means of the relative rotation of thescrewthreaded portions of the case, will cause the compression of the elastic ink-fountain O, and

' 3 force the ink upward into the cavity of the dip-cup, and a reverse rotative movement of the screw-threaded portions will cause the withdrawal of the ink from the said cavity.

I claim as my invention- 1. An inkstand having an elastic ink-fountain a dip-cup, and a case made in separate parts, which are connected by means of opposite screw-threads, whereby upon revolving one of the said parts upon the other the vertical height of the chamber which holds the inkfountain will be either increased or diminished, substantially as and for the purpose specified.

2. An inkstand having an elastic ink-fountain and acase for holding the ink-fountain,

the said case having a screw-thread upon its inner surface, the bottom plate or foliowerbeing provided upon its periphery with ascrewthread fitting the inner screw-thread of the case and adapted by rotary movement to change the vertical height of the chamber for the ink-fountain, substantially as and for the purpose specified.

3. An inkstand having a case or frame with a neck or flange provided with ascrew-thread upon its exterior surface, an elastic ink-fountain and means for compressing the same, a

dip-cup or dipping-aperture, a screw-cap fitting the exterior screw-thread of the neck or flange, and a stopper pivoted in said capand adapted to close the dipping-aperture, substantially as described.

SAML. DARLING.
