INKSTAND.

Specification of Letters Patent No. 30,257, dated October 2, 1860.

To all whom it may concern:

Be it known that I, SAMUEL SLocoMB, of Cambridge, in the county of MiddleseX and State of Massachusetts, have invented an Improved Inkstand, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure l is a view of the inkstand. Fig. 2 a vertical section through the middle of the same.

The object of my present invention is to produce an inkstand in which the ink may be readily raised and lowered; and my i11- vention consists in closing the aperture in the bottom of the ink cup by means of a pin or projection in the bottom of the well, whereby I am enabled to produce an inkstand entirely of glass, durable, and of small original cost, in which the ink is held suspended without other packing, or of tightfitting joints as has heretofore been required, and which soon become inoperative from wear.

That others skilled in the art may understand and use my invention I will proceed to describe the manner in which I have carried out the same.

In said drawings, A is the body of the inkstand, in the bottom of which is formed a well B. The ink cup C at its lower end forms a piston a, which fits loosely in the well B, the upper part or neck I) of the cup also fitting loosely in the top 0 of the stand. The recess (Z in the interior of the cup C is continued down through the bottom of it making a passage 6, through which the ink rises into the cup. A pm or projecting piece f on the bottom of the well B fits the mouth of the passage 6 and by closing it when the piston a descends prevents the ink from flowing back from the cup into the body A of the stand.

As the cup C, as well as the body A and 1 pin 7", are all of glass, (china or other suitable material may be used,) there is no part liable to be corroded, gummed up, or otherwise injured by the ink. This inkstand is easily kept clean, and having no packing of a destructible material is not liable to get out of order.

The following is the manner of operating this inkstand: The body A being partially filled with ink, the cup O is entered in the position shown in the drawings. As the piston a descends into the well B the ink is forced up through the passage 6 into the cup C, and when the piston reaches the bottom of the well the pin 7 entering the mouth of the passage 6 prevents the return of the ink.

lVhen it is desired to empty the cup C, (after a person is done using the inkstand,) it is only necessary to raise the cup gently for a short distance to open the mouth of the passage 6, when the ink will flow back to find its level in the body A of the stand.

I prefer to grind the pin f into the mouth of the passage 0 in a manner similar to that in which bottle stoppers are ground in.

\ Having thus described my invention, I would state that I am aware that, a well, and a plunger with hole through the latter has been used in inkstands, and that rubber and other packing has been used in the bottom of the well, or on the end of plunger. These I do not claim, but

What I do claim is In combination with a well, and a hollow plunger, the projection f, formed of the same material, and at the same time that, the bowl of the inkstand is formed, and fitting into the opening 6 in the plunger, as herein set forth and represented, and for the purpose specified.
