*rares ATTACHMENT FOR INKSTANDS.
SPECIFICATION forming part of Letters Patent No. 443,937, dated December 30, 1890.
Application led September 24, 1890. Serial No. 365,984. (No model.)
To all whom it may concern:
Be it known that I, BARCLAY lll. EVERSON, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Inkstands; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in attachments for inkstands; and it consists. in the construction which will be fully described hereinafter, and pointed out in the claims.
The objects of my invention are to provide an attachment for inkstands whereby a slight downward pressure of the pen will cause the air in the ink-well to be compressed and force the ink up to the pen, to form a cover, stopper, or diaphragm in one single piece, part of which is formed of hard rubber and the other of soft, and to provide a means for expanding the cover in case it is too small to fit in the mouth of the inkstand.
Figure l isavertical section of an inkstand, showing the attachment forced inside of the mouth. Fig. 2 is a similar view showing the attachment ot' somewhat different construe tion sprung` over the top of the mouth of the inkstand. Fig. 3 shows the thickened portion of the stopper in a reversed position from that shown in Figs. l and 2. Fig. 4 is a perspective of the ring used to expand the covers, if they are too small to tit the mouth of the inkstand. Fig. 5 shows diierent forms of my invention.
A represents an ordinary inkstand or bottle of anydesired size, shape, or construction, and B represents my attachment which is to be applied thereto. v This attachment consists of the central tube C, having the usual funnel formed at its upper end, and which extends any desired distance down into the bottle, and the cover or diaphragm proper D, which is formed of soft rubber having any desired amount of flexibility, and which is preferably formed as a part of the tube O. The outer edge F of this cover D is made much thicker than the flexible portion and is provided with a vertical wall, which is intended to be turned downward, so as to tit either inside of the mouth of the inkstand or to catch over the iiange formed upon its top, as shown in Figs. l and 2, or it may be turned upward, as shown in Fig. 3, and tit inside ot the mouth alone. The contact of this thickened portion F, whether forced inside of the mouth of the bottle or made to catch over the flange upon its top, forms an air-tight joint. lf this thickcned portion is turned downward, as shown in Figs. l and 2, the upper end of the tube C will be raised considerably above the top ot' vthe inkstand; but if it is desired that the tube shall project above the top of the inkstand but a veryshort distance the thickened portion F will be turned upward,as shown in Fig. s.
While the entire attachment is preferably to be made in a single piece, as shown in Figs. l and 3, this construction is not absolutely necessary. Vher'e they are made in a single piece, the tube C will be independently hardened or vulcanized, While the other portion will remain soft and elastic. Through the thickened portion F will be made a small airhole G, which is to be kept closed by means of a plug while the inkstandis in use. When it is desired to till the inkstand, this plug is to be removed, so as to allow a free escape of air, and then the ink can be poured in the funnel upon the upper end of the tube C. By removing this plug at any time While the inkstand is in use the expanded air in the top of the well will be allowed to escape and thus prevent the expansion from forcing the ink up into the tube.
Should it be desired to form the tube C ot' glass or any other suitable material independently of the flexible portion ot the cover, stopper, or diaphragm, the flexible portion will be formed as shown in Fig. 2, Where the central part or portion I is funnelshaped and provided with an inwardly-projecting flange J at its top. The ink-tube is then inserted into the cover, as shown, the flange J catching over the upper edge of the tube, as shown. `Where the covers are too small to fit naturally the mouth of the inkstand or bottle, they may be expanded to .any desired extent by inserting the ring N (shown in Fig. 5) inside ot the outer thickened portion of the cover. This ring, as shown in Fig. 5, has its two ends IOO reduced in size, and the ends of the ring are provided with ratchets, so that. the ring will vremain at any size to which it is adjusted. Adjusting this ring to any desired size after it has been inserted in the cover causes the cover to be expanded proportionately, and in this way the thickened portion may be en larged, so as to make a tight joint with inkstands having mouths too large for the cover in its natural condition. The portion D of the cover, stopper, or diaphragm being elastlc a very slight downward pressure of the pen upon the upper end of the tube C Will cause the ink to rise to the pen, and as soon as the pressure of the pen is released the ink drops back into the inkstand again. This cover being' made to close 4the mouth of the inkstand, no evaporation of the ink can take place, all dust and dirt are prevented 'from falling into the inkstand, and the ink is prevented from becon'iing too thick for use.
By forming the entire cover, stopper, or diaphragm of a single piece instead of a number of pieces, as has heretofore been the case, the construction is greatly cheapened and simplified, the parts are not so liable to get out of order, no screw-threaded cap or collar is necessary to hold the attachment upon the -inkstanch no leakage can take place between the flexible portion D and the tube C, While leakage is apt to occur where they are made separate, the tube cannot be withdrawn from the diaphragm, which always rhas a tendency to destroy the soft rubber, and thus ruin the air-tightjoint which should beformed between them, and there is no need for screw-threads at any place above the cover for any purpose.
Owing to the tlzinness of the diaphragm it is impossible to make a tight joint bet-Ween it and a tube which passes loosely through it, and therefore I form them, preferably, integral, as before described, so that joints are avoided.
Having thus described my invention, I claiml. Au attachment for inkstands, consisting of a reversible stopper formed of rubber, having a thick lower annular portion which is provided with a Vertical wall and a thin dexible central diaphragm, whereby the stopper may be placed inside or outside of the mouth of the bottle or the thickened portion turned above or below the diaphragm and a tube passing through the'diaphragm, substantially' as shown.
2. The combination of the cover, stopper, or diaphragm formed of flexible and hard material, as described, and which is adapted to fit inside of the mouth of an inkstand, with an expanding device which is to be placed inside of the outer edge of the attachment, substantially as specified.
In testimony whereof I aiiix my signature in presence of two witnesses.
. l. M, EVERSON.
