INK-WELL.

SPECIFICATION forming part of Letters Patent No. 430,911, dated June 24, 1890.

Application filed March 7, 1890.

To all whom it may concern.-

Be it known that I, JOSEPH B. ANTES, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Inl -\Vel1s, of which the following is a specification.

The object of this inventionis to construct an ink-well which will contain in reserve a supply of ink, and in which but a small quantity of ink is exposed. 1

In the accompanying drawings, Figure 1 is an isometrical representation of an ink-well embodying the features of my invention. Fig. 2 is a vertical central section of the same, in which the ink-cup is in its normal position. Fig. 3 is also a vertical central section of the ink-well shown at Fig. 1, in which the ink-cup is lowered to a position which it will occupy while being filled with ink.

The ink-well shown in the drawings is, in the main, constructed of glass of any suitable pattern, and which may have its exterior surface ornamented to suit the requirements of the trade. The lower portion 1, in this instance, is of cylindrical form, having its center portion recessed and provided with an outwardly-projecting flange 2. The portion 3 above the flange is reduced in size. The upper portion or cover is also of cylindrical form, having its under face recessed, said recess being of a size to receive the upper portion 3 of the lower section of the ink-well. The inner surface of the vertical Wall of the recessed portion of the cover and the outer surface of the reduced portion 3 of the lower section of the iuk-well have a ground-glassjoint connection, so that when the parts are placed together in the position shown in the drawings an air-tight joint is formed, the object being to prevent the admission of air to the reserve supply of ink within the well to prevent its evaporation and the consequent thickening of the ink Within the well. An ink-cup 5 is preferably constructed of glass, having a reduced portion 6, the outside of which is ground, as in the manufacture of glass stopples for bottles. The upper portion of the cup fits into a recess 7, formed in the under side of the cover, and when in its raised position comes in contact with a packing-rin g 7-,}, of rubber or other suitable material, secured within the recess, thereby forn1= ing an air-tight chamber. The cup proper is supported by its lower portion being fitted into a bracket 8, having a connection with a vertically-moving rod 9, which passes through an opening in the cover. A disk of rubber 10, or other suitable packing, surrounds the rod 9, and when the cup is in the position shown in Fig. 2 said rubber disk closes the opening through which the rod passes through the cover.

The rod and bracket are constructed of some non-corrosive material, such as hard rubber. The upper end of the rod 9 is provided with a cap 11, having its upper face concaved,which'for1ns a place for the finger. From this cap laterally projects a collar 12, which surrounds a spring-containing tube 13. This tube passes through the top of the cover, and has a shoulder 14:, which rests on the upper surface of the cover. A portion of the tube which extends below the cover is in screwthread form, upon which is turned a nut 15, which when turned up against the under side of the cover firmly clamps the tube in position and makes an air-tight joint between the tube and cover, the lower end of the tube being closed. Within the tube is placed a spiral spring 16. A plug 17 is placed within the tube after the spring has been placed inposition, and has a'connection with the collar 12 by the screwlS, passing through the collar into the plug through a vertical slot 19. The rear face of the tube 13 is screwthreaded, and when the parts are placed in position, as shown in the drawings, a screwthreaded cap 20 is turned on the upper end of the tube, thereby preventing the displacement of the parts and closing its open end. This tube, its various parts and connections with the rod 9, are also preferably made of hard rubber, excepting the spring, which by being placed in the tube is protected from the action of the ink.

Around the rod 9 is pivoted a cover 21, which can be moved to close the opening 22, formed through the cover over the ink-cup when the well is not in use.

In use the cover portion of the well is removed and the lower portion is nearly filled with ink. The cover portion is then placed in position by pressing on the rod 9. The

when it is necessary to do so.

with in k, when by releasing the rod its sprin g connection with the cup will cause it to assume its normal position, as shown in Figs. 1 and 2, and this operation may be repeated until nearly all the ink has been used.

When the parts are in their normal position, the main body of ink within the well is protected from the action of the atmosphere, and is only exposed to the atmosphere during the refilling of the cup. This cup is made detachable to permit of its being cleansed an ink-cup in this manner the sediment portions of the ink will remain in the bottom portion of the ink-well, and only the pure ink will be taken up by the cup for use.

By means of the flange 2 the ink-well may be suspended in an opening formed in the upper surface of a table or other support,

thereby exposing to view only the upper portion of the well, which in many instances will be preferable where a high inkstand is not desirable; but it is evident that ink-wells may be made without this supporting-flange and still be within the meaning of my invention.

I claim as my invention- 1. In an ink-well, the combination of a lower section, a cover thereto having an opening in its top, avertically-slidin g rod passing through the cover, and an inkcup supported by said rod in'a removable manner, for the purpose set forth. 7

2. In an ink-well, the combination of alower section, a cover thereto having an opening in its top, a removable ink-cup when in its normal position supported beneath said opening, a vertically-sliding rod passing through the cover and having a connection with the inkcup, whereby said cup can be raised or lowered, a vertical tube having its lower end closed, a spring within the tube, and a connection between the spring and vertical rod outside of the ink-well for holding the cup in its normal position, substantially as set forth.

3. In an ink-well, the combination of a lower By employing section, acover thereto having an opening in thereby forming an air-tight joint, and a re- I movable ink-cup supported within said recess and in contact with the packing-ring, substantially as set forth.

5. In an ink-well, the combination of a lower section and a cover thereto made of glass and having a ground-glass connection, whereby an air-tight joint is formed, said cover formed with an opening in its top, a removable inkcup supported beneath said opening, and a rod of non-corrosive material passing through the cover and forming a support for the cup, substantially as set forth.

6. An ink-well consisting, essentially, of a lower section, a cover thereto having an opening in its top, an ink-cup supported within a recess formed beneath said opening, a rod porting the ink-cup, said rod having a connection with a spring located within a tube which extends vertically through the cover, and a screw-nut for holding said tube in position and forming an air-tight joint in its connection with the cover, the lower end of the tube being closed, substantially as set forth.
