IMPROVEMENT IN INKSTANDS.

The Schedule referred to in- .then Letters Patent and making put of the line.

To all whom tt may concern: v

have invented a. new and useful Improvement in Oombination Inkstand; and I do hereby declare that the following is a full, clear, audexact description thereof, which will enable others skilled in the art to make and use the same, reference being bad to the accompanying drawing formingpart of this specification.

This invention relates to an improved inkstand, which is so constructed that, by adj ustiug an air-vessel, liquid may be fed to a. sponge-cup, or ink or mucilage caused to rise in its reservoir, as hereinafter 4 voirs G and I, through the channels '1 U, so that the air is made to press directly upon the liquid, as seen in the drawing.

described.

In the accompanying drawing-'- Figure 1 represents a vertical section of a combined inkstand,mucilage, and sponge-cup and pin-cushion, taken on the line we: of fig,.3.

Figure 2 is a vertical section of fig. 3 on the line 3 3 Figure '3 is a top view with a part of the air-vessel. removed. v

- Similar; letters of reference-indicate corresponding parts.

inclosing a mucilage-reservoir and cup, and one or more ink-reservoirs and cups.

Bis the bottom, and I G is'the top of the. casing.

D is a sponge-cnp, supported by the top 0.

E isawater-reservoir, which extends from near the bottom B upward through the ,top, consisting of an annular-chamber, inclosing an air-chamber, F.-

The sponge-cup D communicates. with the annular water-chamber E, as seen in fig. 1.

G is the mucilage-reservoir, and

H is the mucilage-cup.-

Irepresents an ink-reservoir or fountain, (of which theremay be any desired number,) and l J the ink-cup.

K is a plate, which slides on the top 0, through which are orifices arranged to correspond with the ink-cup when the iukstand is in use, but which plate will slide so as to cover these cups, and thereby prevent evaporation when not iiruse.

L is a small knob on the sliding plate, by which the plate is operated.

M is the air-vessel, which is simply a cylinder with a closed top, N hearing the pin-cushion 0,; and with 'a stem, 1, attached rigidly thereto. There is a screwthreadon the stern below the top.

q is a-scrcw-nut-on the stem.

R is a bar across the top of the air-chamber F, upon which there is a shortslotted tube, 8. t i

A is an outer casing, of any desired size and shape,

The not q is provided with pins i upon its opposite sides, (see tig.'1,) which pins drop into the slots in S as the air-vessel is adjusted, which, prevents the nut fromturuing round when the air-vessel is turned'for increasing or diminishing the pressure of v the air.

To render the air-vessel operative andlmpartsir pressure to theliquids inth'e reservoirs, and thereby force the liquids into the cups for use, water or other suitable liquid is poured into the sponge-cup D, which finds its way immediately into the annular waterchamber E and packs the lower end of the'air-vessel air-tight.

Theair-chamber F communicates with liquid-reser- By revolving-the air-vessel, and thereby raising or lowering it, the pressure of the air upon theliquids-is increased or diminished as-may be desired,

A new supply of air in the air-vessel can be obtained by simply raising the vessel above its waterpacking.

--By this arrangement all the liquid may be forced from the reservoirinto the cups for use. The sponge is sure to be always wet, as the ink and mucilage cannot be used without water'in the water-chamber.

Every time the liquids are forced into them water is forced into the sponge.

This article is to be madeeriftirely of glass and nonco'rrosive metal, so that it is not liable to get outfof order.

Any liquid other than water, suitable for the purpose, may beused for packing the air-chamber.

As any required number of: reservoirs. or fountains .andcups maybe employed for the various-colored fluids the advantages of this improvement must be obvious. The. ink, the mucilage, and the'sponge are indispensable to the writiug-desk, while the pin-cushion adds great y to the convenience of the arrange ment.

Having thus-described myinventio'n,

I claim as new a desire to secure by Letters Pat.- entp 1. The combination of the adjustable airwessel M, annular chamber E', air-chamber 'F, reservoir I, and cup J, arranged and operating substantinllyas-snecified. .7

2;The combination of the sponge-cup D, annular liquid-chamber E,and air-'vessel'M, constructed and arranged substantially as shown and described.
