Patented Sept. 5, 1950 UNITED STATES PATENT OFFICE INKSTAND Laurence W. Kendrick, Wellesley, Mass., assignor to The Carters Ink Company, Cambridge, Mass., a corporation of Massachusetts Application August 11, 1945, Serial No. 610,277

4 Claims. 1

The invention relates to an improvement in inkstands and especially those of the combination type in which a container, or bottle, containing ink is combined with the inkstand.

Among the objects of the invention is to provide a construction which will prevent leakage in case the inkstand is overturned; also a construction that will materially lessen evaporation of the ink.

The construction of the inkstand is also such as to embody various new constituent features, all of which can best be seen and understood by reference to the drawings, in which-- Fig. 1 is a front elevation of the inkstand.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a top plan of the inkstand with the ink container, or bottle, and its cover removed.

Fig. 4 is a cross section of a detail of construction to which special reference will later be made; and

Fig. 5 is a section on the line 55 of Fig. 1.

Referring to the drawings: i represents the base of the stand, preferably a hollow base. The base is preferably made generally rectangular at the back, and brought forward to present a rounding front 1'.

Supported from the base is an enclosure 2, generally rectangular in form, with side walls 3, 4, "5 and 6, and a bottom I. Formed Within and by this enclosure is a reservoir 8 filled from a container, or bottle 9, containing ink, which occupies an inverted position within the ink stand, and is supported as will later be explained.

Located within the enclosure 2 is a partition or diaphragm l havin upstanding flanges H which make closed connection all around with the inside surfaces of the side walls 3, 4, and 6 of the enclosure. The partition has a depressed portion H (see Fig. 2) having a bottom I3 within which is an opening I4. The bottom of the depressed portion of the partition and the opening within it occupy a vertically spaced relation to the bottom I of the enclosure forming the reservoir.

The ink container or bottle is preferably one provided with the cap l5 having threaded connection with the neck l6 of the container, and this cap, when the container is occupyin an inverted position in the inkstand, is located within the depressed portion i2 of the partition. The cap has an opening ii in it. This opening is controlled by a valve l8 which prevents the escape of ink through the opening in the cap when the container is being held in an inverted position for placing it within the inkstand.

2 During this operation the valve on the cap will pass through the opening in the bottom l3 of the depressed portion of the partition and engage the bottom I of the enclosure, and thereupon the valve will be opened and ink will issue from the container to fill the reservoir.

When the cap I5 to the container 9 is located within the depressed portion of the partition 9. portion of the surface of the cap around the opening H in it will occupy a circumscribing relation to the opening M in the bottom l3. A compressible seal forming annular washer I9 is interposed between said cap, and the bottom l3 of the partition around the opening [4 therein. The washer is preferably cemented to the bottom l3 of the depressed portion of the partition. A seal will accordingly be formed between the opening I! in the cap andthe partition around the opening It in it, upon the application of pressure to the container for compressing the washer, and ink issuing from the container will then pass only into the reservoir. Pressure is applied to the container for compressing the washer, and forming the seal, in the following manner.

Mounted upon the enclosure 2 is a cover 20 which is detachably secured to the enclosure, the enclosure and the cap co-operating to form a housing for the ink container, or bottle.

Interposed in a space left between the top end of the inverted container, or bottle, and the adjacent top end of the cap is a pad 2| of some flexible elastic material which will become compressed when the cover is attached to the enclosure. The pressure of the compressed pad against the container acts through it to compress the washer !9 and form the seal between the end of the container and the partition around the respective openings therein.

The cover, and, for that matter, the entire stand, apart from the ink container, or bottle, is made of plastic material which in itself has a certain amount of elasticity when in a thin plate, as in the cover, and accordingly may be deformed slightly by pressure, and returned to its normal shape when the pressure is removed. The bottom end of the cover fits within the top of the enveloping walls of the enclosure, and preferably in bearing engagement with the top edge to the flanges ll of the partition or diaphragm I 0. The opposite fore and aft sides of the cover along their bottom edges are provided with clips 22 which, when the cover is distorted by pressure, are brought into position to enter sockets 23 formed in the top edges of the adjacent walls 3 and 6 of the enclosure so that when the deforming pressure upon the cover is removed these clips will enter the adjacent sockets and the cover will be attached to the enclosure, its detachment being obtained by again deforming, and releasing the clips from their sockets, whereupon the cover may be removed.

The ink reservoir 8 lies between the bottom 'I of the enclosure 2 and the bottom [3 of the partition or diaphragm. The bottom I of the enclosure is provided with a cutout by which ink in the reservoir may enter and lie contained within an underlying dipwell 25. This dipwell has a bottom 26 and sides 21 which lie in closed connection with the edges of the cutout in the bottom of the enclosure. The bottom and side walls of the dipwell extend forward beyond the fore end wall 6 of the enclosure 2 and connect "with a hollow upward extension 28. This extension passes upwardly by the front end wall 6 or the enclosure, making closed connection therewith and lies contained within a molded front '29 of the inkstand which extends fromtheround- =ed front l of its base portion and merges H with the front of the enclosure 2'. This molded front has an upwardly rounded central portion 30 with an opening 3| in it and the top edges of the upward extension 28 of the dipwell make closed connection all around with the edges of this opening. The opening is closed by a plate 32 bearing a pen receiver or holder 33 whichextends downwardly into the upwardextension 28 and through which entry is had to the dipwell.

Ink will rise in the ink reservoir and dipwell only to a point substantially level with the opening M in the bottom of the partition, for when the reservoir 8 has been filled to a point where the opening [4 in the bottom of the partition has become closed by the ink, then air can no longer enter the container, and ink cannot issue therefrom until the level of the ink in the reservoir has become lowered to permit-oi the entrance of further air through the opening in the bottom of the partition.

With an inkstand as thus constructedn-o ink can escape from "the inkstand if turned overupon its side or upon its back. Evaporation-of ink will be reduced to a minimum -for the only opportunity afforded for evaporation is by way of the entrance to the dipwell, and this entrance is usually closed when the inkstandis not innse, by leaving the pen in the receiver or holder 1.
