RHODES LOOKVOOD, OF BOSTON, MASSACHUSETTS,

ASSIGNOE TO THE DAVIDSON RUBBER COMPANY, OF SAME PLACE,

INKSTAND.

SPECEEICATION forming part of Letters Patent No. 359,214, dated March 8, 1887. Application filed October 26, 1386. Serial No. 217,253. (No model.)

To a/ZZ whom it may concern:

Be it known that I, RHoDEsVLocKwooD, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Inkstands, of which the following descrip tion, in connection with the accompanying drawings, is a speciication, like letters on the drawings representing like parts.

This invention is an improvement upon United States Patent No. 324,393, granted to me August'lS, 1885, and it consists in various details of construction, to be hereinafter described, whereby a much more eilicient inkstand is produced.

Figure l shows in vertical section an inkstand embodying this invention; FO. 2, a top view ofthe ink-receiver, the button through which the nib of the pen passes being removed; Figs. 3 and 4, side and top views, respectively, of the movable bottom plate; Fig. 5, a vertical section ot the outside shell or case; Fig. 6,a cross section of Fig. 7,and Fig. 7 aside view of the interior metallic frame.

The ink-receiver or top piece, e, preferably made of hard rubber,is p rovided with a screwthreaded portion, c, having a central conical opening, e2, in which is placed a button,e",also having a conical opening. rThe top piece is provided upon its under side with an annular flange, esurrounding the ink-receiving cavity, the ink-reservoir a, made of vulcanized rubber or other elastic material, being stretched over the said flange c4. A cap, h, is secured upon the screw'threaded portion e of the top piece, c. The top piece, e, is also screwthreaded, as at c5, to t upon or receive the top portieri, m', of a metallic ring-like frame, m, (see Figs. l, 6, and7,) said frame m having a base, mi, joined with the screw-threaded portieri m by arrows or uprightsmi, three such arms or nprights being` shown.

The outside shell or case, a, having at its interior a spiral groove or thread, a', surrounds loosely the metallic frame m between the iiange m2 and collar 2 of the top piece.

The arm's or projections o of a bottom plate, o, passes through .the openings between the upright-s m3 of the frame m., and enter or engage the spiral groove a of the outside shell or case, a, so that as the shell or case a is rotated the bottom plate, 0, will be madeto rise and fall.

The body of the ink-reservoir a rests upon the bottom plate,o,as in the patent referred to.

The operation of raisingthe ink well Orreservoir and causing the ink to enter the conical recess e2 is the same as in the said patent.

It is obvious that the frame m may be made of hard rubber or other material, if desired, and also instead of having three uprighrs, to thereby leave three openings in its side walls, any other number may be employed.

By providing the top piece with a button, e3, the latter may be removed at any time, to facilitate emptying or clearing the ink-reser- Voir.

By makugthe frame m and top e as separate pieces the cost of production is simpliiied, and by using metal for the frame the inkstand is made stronger and at heavier, so that it will stand withless liability of being overturned, the flange ml adding weight to form a foot.

The ink-reservoir is made as a sack with a tubular neck, which may be drawn over the flange e, and which may be readily removed from the said iiange by simply unscrewing the top piece, e, from the frame m.

The reservoir, circular' in cross-section, is contracted, as at 3, between its ends, to make it more flexible and insure that the walls ofthe reservoir turn inwardly as the bottom plate is made to approach the top piece.

I claiml. In an inkstand, the top piece having the ink-receiving recess combined with the separable frame m, having openings in its side walls and engaged by said top piece, the spirally-grooved outside shell or case, a, and the bottom plate, o, substantially as described.

2. In an inkstand, the top piece having the ink-receiving recess e2 and the button c, having the conical aperture, combined with the separable frame m, having openings in its side walls and engaged by said top piece, the spirally-grooved outside shell or case, a, and the bottom plate, o, substantially as described.

3. In an inkstand, the top piece having the ink-receiving recess l and the button e, having the conical aperture, and an annular iiange,

the same time- 5. In an inkstand, the top piece having the ink-receiving recess e2, combined with a removable button, es, having a conical aperture, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
