SPECIFICATION forming part of Letters Patent No. 767,856, dated August 16, 1904.

Application led March 2l, 1904.

To @ZZ 1071/071@ 'it muy concern:

tle as from a reservoir; but within the limits of the invention a-reservoir other than the bottle in which the ink is sold can be used. The reservoir may be open; but a closed reservoir is more particularly employed. The cup holds the ink into which the pen is dipped.

In accordance with the invention the inkstand is composed of a reservoir and a communicating cup, connected with each other through the medium of a neck or a substitute therefor, such as a hole or socket, on the res ervoir, and is provided with a device in the nature of a valve, which opens and closes the communication between reservoir and cup, according to the position thereof, without re quiring the cup and reservoir to be disconnected for the purpose. Most advantageously the reservoir has in its neck a vent (in other words, an aireinlet opening) distinct from the discharge-opening, through which it supplies the cup, and this vent is opened and closed at the saine time as said discharge-opening. By opening the valve the ink will run from the reservoir into the cup it the reservoir and cup are placed in proper relative positions, and when a proper supply has been received in the cup the closing of the valve retains ink in the reservoir. By using a bottle or other forni of closed reservoir no evaporation can then take place from the ink in the reservoir. Moreover, the cup and reservoir can be so arranged that the ink can be returned to the reservoir by inverting the reservoir and cup and adjusting the valve to open the communication between them. The valve might be formed in various ways within the limits oil the invention, since I believe I am the iirst to devise an inkstand in general oi' the preceding description with or without a vent Serial No. 199,218. (No model.)

distinct from the discharge-opening; but it is an advantage and further improvement to have the valve united to the cup and movable therewith relatively to said reservoir, so that to adjust the valve the cup is turned or otherwise appropriately shifted. The cup then takes the place of a wheel or handle for manipulating the valve. By having the two united the construction is simplified, and by utilizing the cup as the manipulating device for the valve the liability of soiling ones tingers in shifting the valve is lessened. So far as I am aware it is new, broadly, to combine a reservoir with a communicating cup and a valve united to said cup and movable therewith relatively to said reservoir for opening and closing communication between the reservoir and cup, and such combination is therefore included in the invention without reference to the manner of connecting the reservoir and cup, although an additional claim is made tothe same when the cup and reservoir are connected by a neck or its substitute on the reservoir.

For securing the cup to the reservoir a plug-and-socket connection is advantageously employed, the rotation or other movement of one part of such connection relatively to the other being utilized to shift the valve for opening and closing the communication be'- tween 'the reservoir and cup, andit is considered more advantageous that the socket part of the connection should be in the form of a movable sleeve, screw-threaded or otherwise suitably formed, the plug part being immovable on the reservoir so far as the operation oi' the valve is concerned. This more advantageous arrangement is secured in one form of the invention by having a sleeve which is united to both the valve and the cup and is movable with both to fit over an outwardlyprojecting' neck on the reservoir, while-in another form said sleeve iits over the outer end -oi` a perforated stopper whose inner end constitutes a plug in the bore of such neck.`

So far as I am aware I am the first to combine either a cup or a cup and a valve with a reservoir by the aid oi' a sleeve, which is united to such cup or such valve, or with both, and is movable therewith relatively to said reservoir, and such general combinations, all and singular, are included in the invention as well as a cup or a cup and valve ha\f'ing an attaching-sleeve united to and movable with the cup or valve, or with both.

The cup may be made in various forms; but it is an advantage and special improvement to make it annular. A

Further improvements consist (c) in providing the cup with a lid pendent in the mouth of the cup, which lid can readily be pushed aside to insert the pen, and (7)) in providing' a division-plate inside they cup on the back wall `of the same to confine the ink when (the cup 'as to serve as a filling as well as a discharge opening, or an additional filling-opening can be provided.

, A bottle or reservoir provided with a neck and also with an integrally-formed closure perforated with a discharge-opening and a vent is believed to be broadly new and is so claimed.

Abottle or reservoir provided with a neck or its substitute and an additional filling-open- .ing formed in a second neck or otherwise constituted forms part of the invention where said neck or its substitute is provided with a closure (integrally formed or otherwise constituted) perforated with a discharge-opening and a vent.

The invention also comprises the additional parts, improvements, and combinations hereinafter :set forth.

In the accompanying drawings, which form part of this specification, different forms of inkstand are illustrated, each of which is in accordance with the invention or parts thereof. Modifications, additions, and omissions can be made so long as the substance of any one or more of the hereinafterwritten claims is taken.

Figure l is a 'front view,\ and Fig'. 2 avertical longitudinal section, of an inkstand with double-necked reservoir. Fig. 3 is a partial View, in vertical longitudinal section.of an inkstand whose reservoir has a single screwthreaded neck; and Figs. 4:, 5, 6, 7, 8, 9, l0, and

ll are views in vertical longitudinal section of other forms, Fig. 10 being a complete view in such section and the other 4iigures partial views. i

In Figs. 2, 3, 4, 5, and 9 the valve is shown in position to close the communication between the reservoir and cup, while in Figs. 6, 7, 8, and 1l it is shown in the opon position.` lIn Fig. l() a self-feeding arrangement is illustrated with the valve closed.

In practice ink is commonly sold either in bottles with plain neck closed by a solid cork or else in bottles with externally-threaded neck closed by a screw-cap or else, thirdly, in bottles with plain neck closed by a perforated stopper provided with an externallyscrew-threaded portion and a screw-cap over the end. The cup of the present invention can be adapted to any of these forms, the cap or cork being removed, or it can be adapted to other forms of bottle.

Referring to Figs. 1 and 2, the reservoir a p is provided with two necks I) and c. The neck is screw-threaded externally and would be closed by a screw-cap if the reservoir a should be used as a shipping vessel. Vhen the ink is to be used, the cap would be taken off. rlhe neck c is a plain neck and surrounds a iilling-opening which is closed with the solid cork (Z when the reservoir has been filled. For refilling the cork CZ can be withdrawn and replaced. The ink` is discharged through the neck I).

The cup e isconnected with the reservoir through the neck and communicates with Asaid reservoir through a discharge-opening in said neck. As shown, there is a plug-andsocket connection between the cup and reservoir, the sleeve f, which is united to cup, forming the socket part of the connection, while the neck b forms the plug part. The

IOO

two engage by their screv-threads. The

sleeve f thus forms a rotatory attaching device. To prevent ink from leaking out between the sleeve and neck, a packing-ring f say of soft rubber or other suitable materialmay be interposed between the end of the sleeve and the body of the reservoir at the base of the neck I).

The cup e is provided with a valve for opening and closing the communication between the reservoir and cup, which valve, as shown, is movable with both the cup e and its rotatory attaching device f and is constituted by the disk t. At the edges of the disk there are holes j, best in the form of slits, and when the cup e, with its sleeve f and valve-disk L, is screwed out these holes are brought beyond the end of the neck so that ink can flow out of one hole j' while air enters by the other.

Behind the valve-disk is a packing-disk 1, whose periphery is held in a groove. When the cup, with its sleeve and valve-disk, are screwed in, the packingdisk c is pressed against the mouth of the neck completely closing the same.

As shown, there is in the mouth of the neck an integrally-formed closure l, perforated with a vent (or air-inlet) m Vand a dischargeopening fn..

At j) is a low partition or division-plate.

IIO

each of two reasons: First, it furnishes a peripherical rim for turning the sleeve f in screwing the same onto and off of the neck as well as in turning it to open and close the valve, and, second, it furnishes a receptacle for the ink in almost all positions of the reservoir and cup.

As shown, the neck b is eccentrically placed; but it is not necessary that it should be so arranged. In Figs. 4, 6, 7, 8, 9, and 11 aconcentrieally-placed neck is shown.

The reservoir a might be of any shape, but is shown as square in cross-section. Vhen placed on one of its sides, it is not liable to roll. It does not need a stand to-restrain it. With an annular cup the reservoir (whether square or cylindrical) could rest on any one of its sides, (the plate r being properly hung or dispensed with.) If made to rest on what is, as shown, the top of the reservoir, the opening 1n would become the discharge-opening and the opening n the vent.

If the ink is Ashipped in the reservoir a, one would remove the cap from the neck I) and screw the sleeve f over said neck, the reservoir being held in an upright position., Then placing the reservoir on its side, as shown in Figs. l and 2, and adjusting the disk /L so as to bring the holes j beyond the end of the neck, ink will flow out of the reservoir into the cup. When the desired quantity of ink has been received in the cup e, this latter, with its sleeve f, is so turned that the disk /i presses the packing against the end of the neck and arrests the outflow. The pen is dipped into cup e through the opening in theY front of the cup, the pendent plate r (if used) being pushed aside.

When the ink in the cup needs replenishing, the valve is moved to reestablish the communication between the reservoir and cup, and, if necessary, the reservoir is tilted to make the ink flow into the neck Instead of laying the reservoir on its side it could be placed on end after supplying the cup e with ink and closing the valve /t y'.

To return the ink to the bottle or reservoirc, the latter is turned upright before opening the valve. The cup and sleeve should be turned sufficiently to bring the lowermost edges of the holes j beyond the end of the neck sothat all the ink will flow out of the cup e. During the operation of returning the ink the plate p would aid in confining the same to the space about the opening ai., so that air from the bottle or reservoir a might freely escape through the vent fm. When the ink has been returned, rotation of the cup e closes the openings m a and prevents evaporation of the ink in the reservoir a. The ink could of c'ourse be returned without the aid of the division-plate p, and, if preferred, such division-plate could be .dispensed with, as could also the pendent plate r and the closure Z; but the use of each and all of them is considered advantageous. In Fig. 9 an inkstand is shown Without division-plate, pendent plate, or closure in the reservoir-neck.

In Fig. 3 the pendent plate r is not shown; neither is there any separate filling-opening, such as furnished by neck c of Figs. l and 2. The discharge-opening a is made large, so as the better to serve for filling purposes. The cup e is annular, but without the peripherical indentations of Figs. land 2. Its shape is also modified otherwise. Instead of having a` packing-ring between the end of the sleeve y and the body of the reservoir, as shown at g in Fig. 2, there is a packing-ring fr set in a groove in the sleeve f and surrounding a cylindrical portion of the neck` which it hugs closely, so as to prevent the passage of ink. In other respects the inkstand of Fig. 3 is the `same as that of Figs. 1 and 2, and its parts are similarly lettered.- In Fig. 4 the tapered end a of an ordinary cylindrical bottle is shown' The plain centrally-placed neck t is closed by the stopper o, perforated by the discharge-opening a and vent m. rI`he outer portion w of the stopper is screw-threaded. The stopper is taken outl in order to fill the bottle. Itis then replaced, and a cap is screwed onto the portion w in order to close the passages m and '11. for shipment. To use this bottle as the reservoir of an inkstand, the cap is removed from the portion iu of the stopper and the sleeve f of the cup e is screwed on instead. The valve /t j is the same as in Figs. l, 2, and 3. Instead of having a packing g between the end of the sleeve fand an opposing shoulder the cup of Fig. 4 has a packing-ring c in a groove in the sleevef, and this ring m slides over a cylindrical portion y, which it hugs closely. It will be understood that any form of packing can be used in any form of inkstand to which it can be adapted.

In Fig. 5 the bottle or reservoir a has a single screw-threaded neck centrally disposed. The division-plate 2J is not exhibited, and the cup e is diderently shaped; but the sleeve f, disk 71,' holes j, packing c, and packing g are as in Figs. l, 2, and 3. The neck b instead of having an integrally-formed closure has a closure in the form of an inserted stopper .fa-say of soft rubberwith longitu?` dinal grooves 2 and 3 in its periphery, said grooves constituting the vent and the dischargefopenings respectively.

In Fig. 6 the cup c is no longer annular, and there is a hole 4 through the disk in place of one of the holes 7' at its periphery. The packing-diskItl is supposed to be cemented onto the surface of the disk L. In other respects the construction is the same as that of Fig. 5. In Fig. 6 the valve is shown open, in which position the hole 4 registers with the vent-groove 2 in the stopper In Fig. 7 the plug part 5 of the plug-andsocket connection is on the cup e (being formed integrally therewith) and the socket part is formed by interiorly threading the neck 6. At the base of the neck Gis a closure 7, formed integral with the reservoir and perforated by a vent 8 and a discharge-opening 9.

the vent 8 and discharge-opening 9, respectively. At 12 is a packing-disk cemented on the end of the plug. When'the plug 5 is screwed home,the disk 12 is pressed over the openings 8 and 9 to close the same.

The cup e in Fig. 7 is not annular; but it has a pocket 13 and a peripherical rim formed partly by said pocket and partly by the continuation 14 of its walls.

In Fig. 8 the sleeve f of the cup e is screwed over the neck b on the reservoir a. This neck has a separately-formed closure consisting of a stopper 15, (say of soft rubber,) perforated with passages 16 and 17, which serve as the vent and the discharge-opening, respectively. The outer end of the stopper is shown as provided with a flange 18, which overlaps the end of the neck I) and iits closely against the inner surface of the sleeve f, (which is here cylindrical,) so as to constitute a packing' to prevent ink from passing' between the sleeve f and neck The disk z. has holes 4 and 19, which are in line with the vent 16 and discharge opening 17, respectively, when, as shown, the cup e and sleeve f are turned to open the communication between the reservoir a and cup e. Vhen the sleeve f is screwed home, the disk /t bears on the end of the stopper 15 and effectively closes the passages 16 and 17, the holes 4 and 19 being no longer in line therewith.

In Fig. 9 the inkstand shown is like that of Fig. 5 only the stopper 7 is dispensed with, so that there is no distinction of vent and discharge-opening, the bore of the neck being fully open. The disk /t in pressing the packing 7': against the end of the neck effectively closes its bore.

In Fig. 10 the reservoir t is double-necked, as in Figs. 1 and 2; but the integrally-formed closure Z of the neck is perforated with an opening 20, which serves -both as dischargeopening and vent. The cup e, which is shown as annular, has only one hole, j. rlhe lower part of its front wall is above this hole, which is the sole means of allowing air to enter and ink to leave the reservoir. Ink,therefore, may

The plug j 5 is perforated with passages 10 and 11, which in the open position of the valve register with lill the lower part of the cup to the level of the hole y', whereupon the flow of ink is arrested until the level of the ink in the cup falls and allows air to enter the reservoir by said hole 7' and opening 20. The inkstand is thus self-feeding. In like manner any of the inkstands shown can be made self-feeding.

It will be observed that inkstand of Fig. 10 would be identical with that of Fig. S2 if one should close the opening a and corresponding hole j', should dispense with the pendent plate fr, and should appropriately modify the shape of the cup e of Figs. 1 and 9. No modification of the cup would be essential, however, to a self-feeding inkstand, because. as shown in Fig. 2, the front wall of the cup e extends inward beyond the holes y', and if the reservoir of Fig. 2 should be placed in the position of Fig'. 10 said front wall would extend above the hole j, which corresponds with opening m, and the ink-could not overflow, provided there was no way for the air to enter the reservoir except through said hole j.

In Fig. 10 the front wall of the cup e is extended not only above the hole j, but also above the opening 20. The ink in the cup e would consequently seal the opening 20, even if the disks /z and f; should be dispensed with. Dispensing with such disks (without proper substitutes) would do away with the valve for closing and opening the communication between the reservoir a and cup e; but while such valve is most useful and an essential element in many of the hereinafter-written claims it is not essential to all of them.

In Fig. 11 the sleeve 21 is lined with packing 22 and turns on the smooth exterior of a neck 23, which is closed by a stopper 15 (say of soft rubber) perforated with passages 16 and 17 for the vent and discharge-opening, respectively. The disk /i has therein two holes 4 and 19,which are brought into line with the passages 16 and 17, respectively, when it is desired to open the communication between the reservoir ct and cup e, as shown. The disk /L may bear at all times against the end of the stopper 15, which would best project beyond the neck Q3, as shown, the turning of the disk merely moving the holes 4 and 19 out of line with the corresponding passages 16 and 17.

The expression in the hereinafter-written claims of features or devices (in the plural) is intended to include one or more such features or devices, and the expression of a feature or device (in the singular) is intended to include one such feature or device at the least and not necessarily to exclude the use of more than one, if appropriate.
