10- Claims.

, This invention relatesto fluid dispensing means and is; particularly useful in. dispensing of liquid, such as ink. The invention, however, may be applied to other uses.

An.- object of-the invention is to provide means fior dispensing ink from a container in such a manner as to make the ink readily accessible for filling fountain pens, ordinary pens, etc. A further object is to provide a base support equipped with a channelin. which pens may be readily filled,. the base support being equipped with means for receiving ink from an inverted bottle or liquid container so as. to. continuously keep said channel, full as longv as ink remains in the container. A further object is to equip an ink bottlev or container with a valved conduit which may be: inverted and inserted within an ink well dispenser, the ink well dispenser being equipped with means for operating the valve to permit the ink to flow into the Well and into an accessible channel communicating therewith. A still further object is toprovide means for supporting a liquid container in inverted position, together with means for causing liquid to flow from said container intoan accessible channel, the liquid within said channel being maintained automatically at a predetermined depth. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in a preferred embodiment; by the accompanying drawings, in which 7 Figure'l is a perspective view of an ink bottle equipped with a valved outlet conduit or pipe; Fig. 2, a perspective view of an ink well support adapted to receive said conduit; Fig, 3, a broken perspective view of said outlet conduit, the same being' shown in inverted position and the valve being shown in closed position; Fig. 4, a view similar to Fig. 3, the valve being shown in open position; Fig. 5, a view similar to Fig. 3 but showing the valve in open position and the inner pipe in raised position; Fig. 6, a broken vertical sectional view, the section being taken as indicated by line 6. in Figs. 2. and 5; Fig. 7, a broken transverse sectional view, the section being taken as indicated at line 1 of Fig. 6; and Fig. 8, a broken vertical sectional view of the ink well support with the conduit-removed, the section being taken as indicated at line 8 of Fig. 6. I

In the illustration given, A designates an ink container or bottle; B, a valved conduit; and C, an ink well support.

The ink container or bottle may be of any suit-- able construction. It is shown equipped, as in usual practice, with a neck A.

The outlet conduit B may be also of any suitable construction and material. In the illustration given, the inner pipe member I0 is equipped at one end with a slightly tapered rubber plug l I which provides a ready connection and good seal between the pipe I0 and the bottle neck A. The inner pipe Ill is openat both ends. It is provided near its outlet end with a discharge slot 12, preferably of the size and shape shown in the drawings. The slot [2 does not quite reach the bottom of the pipe, but. a small band l3 separates the slot from the extreme end of the pipe. As shown more clearly in Figs. 3, 4 and 5, the inner pipe I 0 is provided with a pin l4.

The valve sleeve I5 is closed at its outer end and telescopically receives pipe Ill. As shown more clearly in Figs. 4 and 5, the sleeve I5 is provided: with an outlet slot I6 which is the same in size and shape and coincides with slot 12 of pipe Ill. The sleeve is provided with a guide stud ll. It is also provided with a slot l8 adapted to receive the pin l6 of the inner pipe II). It will be observed that at one end, the slot 18 is provided with an upwardly extending communicating slot I9 which permits the inner pipe [0 to be raised when the pin is aligned with the slot I9.

The base or ink well support may be of any suitable construction or material. In the illustration given, we have shown a circular base 20 which may be formed of onyx, marble, metal, composition products, and other suitable materials. In the illustration given, the base 20 is secured to a metal well member 2| by means of screws 22.

The well member 2| is provided with a vertical well: 23 having, thereina guide vertical slot 24 communicating with a lower horizontal slot 25. The slots 24 and 25 are adapted toreceive the stud H. carried by the valve sleeve l5.

Communicating with the vertical well 23 is a horizontal channel 26. At its outer end, the channel may be, if desired, enlarged to form a convenient pool recess 21' in which the ends of fountain pens, etc. may be dipped. A hinged cover 28' is preferably employed for closing this portion of thechannel;

As shown more clearly in Fig. 2, I' prefer to equip the top portion of the well member 2| with a curved guideway 29 which gradually deepens and meets. the verticalslot 24', thus serving as a guide means for bringing the stud- I1 into engagement with vertical slot 24.

In the operation of the device, the usual cork for the ink bottle A is removed and in its place, the rubber plug H is pressed into tight engagement with the neck A. The valve I5 is rotated to the closed position shown in Figs. 1 and 3. The container now is inverted and the valve sleeve 55 inserted into the well 23 of the well member 2|. Further rotation of the container A causes the stud ll to follow the inclined guide groove 29 until it reaches the vertical slot 24, at which point the stud drops to the end of the vertical slot. Further rotation of the container A causes the stud H to follow the horizontal slot 25 in the well member 2!. However, when the stud H reaches the end of the horizontal slot 25, the sleeve I5 is held against further rotation and when the container A is rotated further, the pin Id travels in slot l8 and at the same time the outlet port l2 of the pipe vIII is brought into alignment with the outlet port 5 of sleeve member 15. When the two ports are aligned, as shown in Fig. 4, the pin I4 prevents further movement which would tend to misalign them. The connection between'the contents of the container A and the channel 26 is now open and liquid may fiow into the channel. We find, however, that for certain flow, it is important to have the vertical slot I9 communicating with horizontal slot I8 of valve sleeve l5 to permit the inner pipe Ill to be raised, this raising operation serving to bring the liquid to the position in the channei indicated by dotted lines in Fig. 6. From this point on, the liquid will maintain constantly the level indicated, until the entire contents of the container have been exhausted. After all of the liquid has been removed from container A, the conduit member B may be removed with container A by reversing the steps heretofore described and, after removal, the resilient plug H may be secured to another container. It will be noted that in the removal of the conduit 5, the inner pipe i0 is turned so that pin [4 moves to the position shown in Fig. 3 and the valve sleeve l5 covers the opening l2 of the inner sleeve, thus eifectively closing the conduit. Thus, any liquid which might happen to be within the conduit is prevented from spilling upon the removal of the container. 7

With this arrangement, one container may be removed while still partially filled and another container substituted therefor-without danger of spilling the contents during the removal operation, since the groove and stud arrangement will not permit removal until after the valve has been closed.

The reduced pressure, which is less than atmospheric, within the container and produced by the lowering of the liquid level. therein, permits the'liquid level withinthe container to remain at a much higher position than the level of the liquid in the dispensing conduit, the atmospheric" pressure upon the liquid in the conduit being much greater than the pressureupon the surface further be obvious that the"device -*m'ay be changed considerably from theillustrated structure shown without departing from the spirit oi our invention.

The foregoing detailed description has been given. for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly permissible, in view of the prior art.
