'1 This invention relates to a liquid dispensing device and refers more particularlyto a closure for containers, which is provided with a valve .or faucet device automatically delivering uniform quantities of a liquid to receptacles of the same size.

Anobj'ect. of the present invention is the provision of a liquid dispensing device which may be conveniently mounted upon a. cap or other closure of a. container and which can be easily operated to dispense a certain amount ofliquid.

Another object is the provision of a dispenser which may be. used in bars, restaurants, laboratories andthe like and which may be placed upon bottles or jars'ior automatically supplying the same amounts of liquid to glasses orother containers of uniform size.

Other objects of the presentinvention willbecome apparent from the following specification.

In accomplishing the objects of the present invention it was found desirable to provide a cap or similar closure member with an elongated outwardly extending tube serving as or carrying a guide for a valve rodprojectingoutwardlybeyond the tube and connected with-a spring'loaded valve body adapted to interrupt the communication between the tube and the interior of the container carrying the closure member. The valve. rod may be rendered quickly interchangeable. for one of diflerent. length as more fully explained hereafter, by forming the. valve seat and the guide for the lower end of the valve rod in a. removable portion-of the tube.

In operation, the valve rod. is pressed against the bottom of a glass or other vessel into which the liquid is. to be poured, thereby compressing the spring and raising the valve body from its seat upon the tube. If the container is placed upside down .over the glass and if the closure member of the container is. provided with an air vent, liquid will flow from. the container and into the glass up to the. level of the. outerendof the vent, the flow ceasing when the liquid has. sealed the vent.

The. invention will appear more. clearly from the following detailed description when taken in connection with the accompanying drawings showing, by way of example, preferred embodiments of the inventive idea.

Eigure- 13 is a side elevation of another form of the device.

Figure 1.4 is a vertical section of the same with the open position shown in brokenlines.

Figure 1.5 is. a top elevation of the same, partly broken away.

The dispensing device shown in Figures 1 to 10 of the drawings is carried by a stopper "H! which is. firmly connected with the. cap or is, integral therewith. The tube it extends beyond the stopper lo and its axis. may coincide with the longitudinal axis. of the bottle.

The tube. M. is provided withan inner web 15 constituting. a guide for a valverod. l1.

That portion of the tube M which is situated within the bottle is provided with outer screw threads 2 and has conical end surfaces constituting a valve seat 25. A distancing ring Hi is'screwed upon the tube Hi and is mounted upon the stopper Til.

A springsupportxiifi has a ring portion 21 which is. provided with inner screw threads and which is screwed upon the threaded end of the. tube M and in contact with the ring it. Two columns if? and 2% connect the ring 2? with the cover 2'9, the inner surface of which has a recess enclosing one end of a coiled spring it. The spring 3! embraces a stem holder 3d through which the valve rod 5'; extends and which is connected by athreaded sleeve 9 with a valve body 35.

The inner end of the valve rod ll extends beyond the support 26.. The outer end of .the valverod ll may extend to a comparatively reat distance beyond the outer end of the tube [4 and may have the form of a ball 32.

The valve body 34 is screwed upon the sleeve 5 9 and is held firmly upon the rod H.

An air vent 37 extends through the stopper m, the column 23, and the cover 29. The cover 29 is, provided with a recess containing a disc i2 which is pivotally mounted upon a pin 1'3 and is maintained in a closing position by a spring 14; in this position the disc '12 closes the air vent 37. As is indicated in Figure 11, the air vent 3? is opened by the engagement of the conical surface 33, of the stem holder 39 in the course of an inward movement of the rod H; the stem holder at will push the disc 52 sidewise to a position in which an opening 75 in the disc 12 will coincide with the air vent 3?.

The operative length of the rod l i may be conveniently varied by loosening the grip of the threaded sleeve l9 upon the rod ll, whereupon the rod is shifted in relation to the holder 30 to the desired extent; then the connections are tightened again.

When no external pressure is exerted upon the rod ll, the valve body as is pressed against the seat 25 by the sprin 3!, so that there is no communication between the interior 38 of the bottle 2 3 and the interior 23 of the tube 14.

In order to dispense a certain amount of liquid contained in the bottle is, the bottle is is placed upside down over a glass 39 or any other Vessel into which liquid is to be poured, and the end 32 of the rod ii is pressed against the bottom of the glass. This pressure causes the rod H to move inwardly, thereby raising the valve body 34 off the valve seat 25 and compressing the spring 3!.

The air vent opens at a point below the minimum level of the liquid in the supply container. Actual experiments which I have carried out show that the flow of liquid from the bottle l3 into the glass 39 will stop as soon as the liquid has reached a certain level in the glass 39, namely the level of the outer end of the air vent 31, and that the amount of the dispensed liquid is the same whenever glasses of the same size are used.

The described dispensing device may be conveniently used in bars, restaurants, laboratories and similar establishments wherein the same amounts of liquid are often dispensed into vessels of uniform size.

The amount of the dispensed liquid may be varied by varying the length of the projecting portion of the rod ii and this is accomplished by changing the position of the valve body 34 and the stem holder to upon the rod ll.

As shown in Figure 1, the bottle 13 may be held conveniently in the upside down position by means of a ring it which is adjustably mounted upon a stem H. A clamp i9 may be used to attach the stem El to an edge of a table 80.

The dispensing device illustrated in Figure 12 is carried by a cap 5! which is aiiixed to the neck of a bottle 52 and which carries an elastic sealing ring 69 interposed between the bottle neck and the cap. In this construction, the tube 14 is eliminated, and the support 29 is mounted directly upon the cap 5i. In other respects, the construction is the same as the one previously described and operates in the same manner.

Figures 13, 14 and i5 illustrate another form of the closure. In this form the tube 8| carries externally a cork 82 or other gasket means adapted to engage the neck of the bottle to seal same. An axial cylindrical passage 83 extends thru the tube 8|, and a spider 84 is located at the top end of passage 83. A threaded tubular plug 85 with a spider 88 is fitted in the lower end of passage 83. A rod 8'! carrying a ball 89 slides in the spiders, and the coil sprin 89 is mounted on the rod between the ball and the upper spider 84. The ball 88 is seated on the upper surface 99 of the tubular plug 85 so as to close the passage 9! therethrough, the bail and plug constituting a valve and valve seat.

The air vent passage 92 extends through the wall of the tube 8! and its upper end 93 projects thereabove, while its lower end opening 94 is formed in the exterior of the tube 8! a substantial distance below the cork 82.

Formed integral with the tube 81 are standards 95 in which the air vent cap 95 is pivoted, and a spring 91 normally keeps the cap in sealing engagement with the upper end 93 of the air vent.

In operation, a bottle l3 containing liquid and with the device inserted is inverted over a glass, preparatory to dispensing the liquid. The portion 98 of the rod 87 projecting below the plug 85 is pressed against the pressure of the spring 89, raising the valve 88 from its seat 90, the upper end of the rod 81 simultaneously swinging the air vent cap 95 away from the air vent upper end opening 93 as illustrated in broken lines. Liquid is thus free to flow through the spider 84, the tube 8|, the passage 94 of plug 89 and the spider 86 into the glass. Simultaneously air is entering the air vent through the lower end opening 94 and escaping from the upper end 93 into the bottle 13. When the liquid in the glass reaches level 97 which is even with the top of opening 94, the air vent will be sealed, Liquid will no longer flow through tube 8! in appreciable quantity because the first few drops that do so flow will create a partial vacuum above the liquid in the inverted bottle, stopping further flow.

It will be noted that the amount which the rod 81 may be raised by pushing on its lower end is limited by the engagement of its upper end with the air vent cap 96. Therefore the distance from the lower end of rod 81 to level 97 is constant, and the amount dispensed will be constant as long as the same size and shape of glass is used. A different amount may be dispensed to the same sized glass by unscrewing the plug 95 and replacing the rod 81 with a rod whose projecting portion 98 is a diiTerent length. Of course the flow may be stopped at any time in any of the above forms of the invention by raising the bottle, or lowering the glass away from the bottle, thus closing the valve.

It is apparent that the illustrations shown above have been given by way of illustration and not by way of limitation, and that the structures above described are subject to wide variation and modification without departing from the scope or intent of the invention; all of such variations and modifications are to be included within the scope of the present invention.
