INKSTAND.

SPECIFICATION forming part of Letters Patent No. 399,844, dated March 19, 1889.

Application filed September 19, 1888. Serial No. 285,773. (No model.)

To (LZZ whom it may concern:

Be it known that I, EMRY DAVIS, of Kane, in the county of McKean and State of Pennsylvania, have invented a new and Improved Inkstand, of which the following is a full, clear, and exact description.

The object ofmy invention is to provide a cheap and practical inkstand, constructed to avoid almost altogether the evaporation of ink; and to this end my invention consists, principally, of a float and dip-funnel, the float being placed loosely in a tube fitted in an airtight cover of the ink-well, so that pressure on the float will depress it and cause the ink to rise and fill the pen. Upon removing the pressure the float rises and the ink recedes, so that only a very small surface is exposed to the atmosphere.

The invention also consists of the construction and arrangements of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my new inkstand. Fig. 2 is a sectional plan view taken on line at .r of Fig. 1. Fig. 3 is a sectional view on line y y of Fig. 1. Figs. 4 and 5 show modifications of the inkstand.

A represents an inkstand or well of glass or other suitable material closed air-tight by a cover, B. This coveris by preference formed of the inner annular and concaved disk, B, of soft rubber, and the outer ornamental metal cover, B flanged and threaded to the stand A, as shown at B Fig. 1.

In the cover B is fitted the tube C, which reaches nearly to the bottom of the ink-well and projects somewhat above the plate B where it is provided with the small ring D, in which fits the small annular cover E for the tube 0. The tube (7 is formed with a flange, I), and the central opening of the rubber disk B is drawn in close contact with this flange, so that the said tube is held air-tight in the cover, and over or above the flange Z) is placed the small soft-rubber ring d to act in connection with the soft-rubber disk 13 to make an air-tight connection between the l tube and cover. The rin g1) is screwed upon the upper end of the tube C, and serves as a nut to connect the tube to the cover, and when screwed down the ring (Z is compressed between the flange b and the inner surface of the outer cover, The outer edge of the softa-u'bber disk D is by preference somewhat thickened or enlarged, as shown at f, to form a cushion between the upper edge of the ink well or stand A and the flat portion f of the metal cover 13, so that when this outer cover is screwed down upon the threads g of the ink-well the cushion f will be .compressed, and the cover a whole made air tight upon the stand A.

In the said tube 0 is placed the float F, in which is fitted the funnel or dip-tube G, which reaches up through the annular cover E. The lower end of the tube (El is open. at the bottom to receive the ink.

In some cases I shall use a light coiled spring, I), at the bottom of the float to lift it suddenly in the tube 0, and this spring may be made fast in the ink-well, or its lower end may be bent to one side to prevent the float F from escaping from the tube 0 in case the inkstand should be upset.

In use, the stand being supplied with ink, the float will be held by the buoyancy of the ink up as far as it can go in the tube, as shown in full lines in Fig. 1. To fill the pen. with ink it is placed in the upper end of the dip-tube and pressed down. This pressure will lower the float F, and the air being confined above the surface of the ink will cause the ink to rise in the dip-tube, as indicated in dotted lines, and fill the pen. On removing the pen the float will be elevated and the ink will recede in the dip-tube, so that there can be practically no evaporation.

In Figs. 4: and 5 the dip-cup II is permanently attached to the cover 13*, and the float F is to be depressed by the direct contact of the pen with the upper end thereof. lVhen so depressed, the ink is forced up the side passages, to a, to the pen, and when pressure on the float ceases the float rises and the ink recedes, and the upper end closes the dipcup II automatically and effectivelyprevents the evaporation of ink.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The body or Well A of the stand, having air-tight cover B, and tube C, fitted in said cover and reaching into the well and above the cover B, in combination with the float F,

placed in the tube, the apertured cover E, closing the upper end of the tube 0, and the tip funnel or tube G, held fast in the float F and projecting up through the said cover E, substantially as described.

2. The outer annular cover, B having screw threaded flange B adapted to be screwed upon the ink-well A, and the inner annular disk, B, of soft india-rubber, held at its outer edge air-tight between the well A and outer cover, B in combination with the tube C, held air-tight in the disk B and provided with the float F and dip-tube, substantially as described.

3. The outer annular cover, B screwed upon the ink well or stand A, and the inner disk, B, of soft rubber, compressed between the outer cover, B and the well A, in combination with the tube 0, having flange b, held air-tight in the disk B, the upper ring, D, upon the upper end of the said tube, the float F, and the dip-tube, substantially as described.

4. The outer annular cover, B screwed upon the ink-well, and the inner cover, B, of soft rubber, compressed between the cover B and the upper edge of the ink-well, in combination with the tube C, having shoulder b, ring (I, placed on said tube above the shoulder 19 and below the outer cover, B, and the ring D, screwed upon the upper end of the tube C, substantially as described.
