INKSTAN D.

SPECIFICATION forming part of Letters Patent No. 368,326, dated August 16, 1887.

Application filed May 26, 1887. Serial No. 289,496. (No model.)

To all whom t may concern:

Be it known that I, SAMUEL DARLING, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in Inkstands, of which the following is a specification.

Myinvention relates especially to that class of inkstands which are provided with an elastic ink-fountain, and the object of my improvement is to simplify and cheapen the construction of such inkstands; and it consistsin making the fountain-case ofthe inkstand in top and bottom portions, which are connected by means of screw-threads, with a revoluble follower pivoted to the bottom portion,whereby the follower is caused to maintain a relatively fixed position with the ink-fountain, which is attached to the top portion of the case, and in an improved arrangement of the follower, elastic fountain, and the case, whereby upon the upward movement of the follower theinkfountain will be pressed into an inverted-cup form, thus expelling` the ink from the outer portion of the fountain and preventing injurious strain upon the rubber wall of the same, and also in theim proved construction and arrangement of parts of the ease, as hereinafter fully set forth.

Figure l is a central vertical section of my improved inkstand, showing the-elastic inkfountain in its expanded condition and lled with ink. Fig. 2 is a similar section showing the ink-fountain in its compressed condition and nearly empty.

In the accompanying drawings, A is the upper or top portion of the case, which is provided upon its lower exterior surface with a screw-thread, c, and B is the base or bottom portion, provided with an interior screw thread, b, which fits the screw-thread a of the top portion. rIhe ink-fountain O is made of india-rubber and provided with a neck, c, by means of which it is to be secured to the upper part, A, of the case.

The follower D is hollowed at its central portion, d, to fit the bulging form of the bottom of the ink-fountain and pivoted within the socket e in the bottom portion of the ease. It is also provided with the downwardly-turned edge f, which extends to within labout twice the thickness of the walls of the ink-fountain from the adjacent wall of the ease. rIhe neck c of the ink-fountain passes upward through the central opening, g, in thetop portion, A, of the case, and is secured therein by means of the forcible insertion of the stem 7i of the dipcup E, which serves to press the elastic neck of the fountain firmly against the wall of the opening g. The upwardly-projecting flange/5 which surrounds the opening g is provided with an external screw-thread, j, which is adapted to receive the interior screw-thread, 7c, of the cap F, and at the upper interior portion of the cap F is placed the rubber packingdisk m, which serves to form a tight joint between the cap F and the upper surface of the dipcup. The cavity n in the dip-cup to receive the ink is made slightly tapering, and at its lower end is placed the removable pengage o, which serves to limit the downward movement of the pen when dipping for the ink, the opening p at the lower side of the pen-gage being made of less diameter than the width of the writing-pen. When iilling the fountain with ink,the pen-gage can be removed upward from the cavity a by means of a hook or otherwise.

The inlefountain in the plane of its greatest diameter is made to nearly fill the horizontal area of the chamber G of the case, so that upon the upward movement of the follower, caused by turning either the upper or lower portions of the case, the bottom of the elastic inkfountain will be carried upward within the upper portion of the same, so that the fountain will be compressed to the form of an inverted cup, which will tend to throw the ink from the outer portions of the chamber H of the inkfountain toward the center of the same, and will also cause the walls of the fountain to be folded without injurious strain, which would cause the rapid deterioration of the rubber. IIhe upward movement of the follower, by causing the compression of the fountain,forces the ink upward into the cavity` a of the dipcup, and the reverse movement of the follower will cause the withdrawal of the ink from the said cavity. Upon screwing down the cap F the cavity n of the dip-cup will be tightly closed, so that the inkstand can be either carried in the pocket or handled without danger 0f leaking.

Whenever the parts of the case are revolved IOO upon each other, the pivoted follower will hold a relatively xed position against the bottom of the fountain, and will not therefore cause the wearing or abrasion of the fountain, as when the follower is permanently fastened to the base B; but it is to be understood that I do notlimit myself to the pivoted'construction of the follower in carrying out my invention. I claim as my invention#- 1. An inkstand having an elastic ink-fountain, a dip-cup, and a case made in top and bottom portions which are connected by screw-threads,and having a revoluble follower` pivoted to the bottom portion, substantially as and for the purpose speciied.

2. An inkstand having a fountain-holding case or frame, an elastic ink-fountain which in its compressed condition, as described, closely fits against the inner side of the said holding case or frame, a follower having aless area than the extreme horizontal area of'the ink-fountain and a downwardly-turned edge,

and means for pressing the followeragainst the bottom of the ink-fountain, whereby the said bottom of the fountain will be inverted within .the top portion, substantially as and forthe purpose specied.

3. An inkstand having an elastic ink-fountain, a dip-cup, and a case having upper and lower portions, the upper portion being adapted to hold and carry theink-fountain and dip-cup, and provided with a screw-thread upon its lower exterior surface, the lower portion havingan interiorscrew-threadfitting the screw-thread ofthe upper portion, and a follower supported by the lower portion and adapted to force the ink from the ink-fountain vinto the dip-cup upon the proper revolution Witnesses:
