To all 'wlwmz't may concern:

Be it known that we, CHARLES DOERING,

J r., and HENRY H. DOERING, citizens of the United States, and residents of Chicago, n the county of Cook and State of Illinois,

have invented certain new and useful Improvements in Devices for Dispensi ng Liquids, of which the. following 1s a description, reference being had to the accompanying drawings, which form a part of our specification.

Our invention relates to a device adapted to dispense liquid in predetermined quantitiesfrom a suitable container or bottle, without the necessity of constantly handling the container or bottle; and, at the same time, permitting the liquid to be sold or dispensed in predetermined uniform quantities in a rapid manner.

A further object of our invention is to provide a device of the character herein specified wherein the quantity to be dispensed may be readily varied, either increased or diminished, by suitable mechanism, the regulations or setting whereof results in a uniform quantity being dispensed at each adjusted position of said mechanism, as will be more fully understood from the following specification.

The advantages above specified and others inherent in the construction will be readily apparent from the following detailed description.

In the drawings Figure l is a side elevation of our device.

Fig. 2 is a front elevation thereof on a smaller scale and shown provided with a liquid-container or bottle inverted into place.

Fig. 3 is an, enlarged vertical sectional view, taken on the line 3-3 of Fig. 2, ooking in the direction of the arrows.

Fig. 4 is a detail perspective view of the liquid-measuring valve.

Fig. 5 is a vertical sectional View, taken on the line 55 of Fig. 3, and looking in the direction of the arrows.

Fig. 6 is a partial longitudinal section and side view of a portion of the liquid-regulating mechanism.

In the particular exemplification of our invention, we illustrate the device provided with a suitable standard or pedestal 10, of any suitable cross-sectional contour and provided with a suitable base-portion 11, whereby the device will be given proper support and may also be permanently secured in place. The upper portion of the standard or pedestal 10 is provided with a port 12 see Fig.3, which extends to the outside of the pedestal or standard 10, and also communicates with the transversely disposed chamber 13, which is preferably shown cone shaped, see Fig. 3, although the chamber may be made of uniform dimensions throughout. The chamber 13 is open at both ends and receives the hollow conical valve 15, which is open at one end, namely the small or reduced end of the valve. The

valve 15 is adapted to fit within the chamber 13 and permit the cap-portion 16 of an elongated regulating member 16, to screw into the end of the'chamber 13, while the elongated portion extends into the openended valve 15, as shown in Fig. 3; the regulating member 16 being shown in detail and longitudinal section in Fig. 6. One end of the chamber, to wit the larger end, is arranged to receive a cap 14, which is adapted to screw onto the end wall of the chamber, as shown in 3.

The general construction of valve 15 is shown very clearly in Fig. 4:, Where it will be seen that the cylindrical wall is provided w1th a pair of ports 17 and 18 arranged at a predetermined distance apart, so as to be alternately brought into register with the port 12 and the upwardly presented port 19, shown in Fig. 3; the latter port extends upwardly from the chamber 13 and com municates with the chamber of the bottle holding portion 20 of the device.

As shown in Figs. 3 and 4, the valve 15 has one end closed, as shown at 15 in Fig. 4; the smaller or opposite end being open, as previously stated, to receive the regulating member 16. The valve. 15 also circumferential wall provided at a predetermined point, with the arcuate port 21, see Figs. 3 and 4,.which is of a length sufiicient to constantly permit the port 21, during rotation of the valve 15, to be in register with the upwardly presented air-port 22, which extends through the upper portion of the standard or body of the device and communicates with the chamber or bottle-holding portion 20, see Fig. 3.

The circumferential wall of valve 15 is preferably extended beyond the end wall 15, as shown in Fig. 4, and as'egment of the extended portion is cut-away so as to provide the shoulders 15 at points substantially in the same longitudinal plane as the ports has its .ber 13, so as to extend into the cut-away portion of the extended wall of the valve, so as to engage the shoulders 15 during rotation of the valve, and thereby limit the movement of the valve, and insure registration of the port 17 and port 12 and registration of port 18 with port 19 when the valve is rotated to its fullest extent in either direction, as is clearly evident from the construction.

The end wall 15 of the valve 15 is also provided with a spindle 2 1, preferably inv tegral therewith, which extends through the cap or closure member 14, and has its outer end provided with a suitable operating handle 25, which may be removably secured in place by any suitable means.

The receptacle holding-portion 20 is preferably in the nature of an elongated tubular member, as shown in Fig. 3, with the upper end preferably flared so as to adapt it more especially to the contour or neck of a bottle, as shown at 26; the bottle being intended to be placed in an inverted condition in the holding-member 20, and maintained in the perpendicular position shown in the drawings. The elongated holding-portion 20 is of such transverse dimension as to provide a suitable air-chamber adapted to be placed in communication with both the bottle 26 and the valve 15, for the purpose of insuring the flow of the liquid from the bottle into the valve and from the latter out through the port 12, from whence it will be discharged by means of the spout 27 into a suitable cup or vessel. I

In order to provide a cushion for the end or mouth of the bottle, so as not to injure the same, and, if desired, at the same time maintain the bottle slightly away from the wall of the holding-portion 20 at the upper flared end thereof, we show the bottom of holding-portion 20 provided with a washer or member 28, preferably of rubber or the like, upon which the mouth of the bottle may rest, as shown in Fig. 3; the member or washer 28 being so arranged, however, as not to interfere with the ports or passages 19 and 22.

The port 19 is preferably provided with the extended portion or tubular member 29, intended to extend into the mouth of the inverted bottle. The upper end is preferably provided with extended converging prongs 29 so as to produce elongated slots, as shown at 30, to permit the flow of liquid, as well as the passage of air, into the bottle.

The construction of the tubular member 29, as described, will prevent the possibility of foreign matter, such as large portions of cork and the like seating itself on the end of the member 29 where it would interfere with a proper fiow of the liquid from the Inorder .to maintain the valve 16 inproper position within the valve-chamber and take up any wear, we provide a spring 32 adapted t6 press against the end wall 15 of the valve 15 and against the cap or 010- sure-member 14-; the ports in the valve being made slightly lar er than the portsinjhe standard or charrilier, so that slight longitudinal movement of the valve, due to wear, may be had without interfering with the proper registration of the ports.

The regulating member or device 16, preferably consists of the elongatedtubular portion, as shown in Fig. 6. The member is preferably internally threaded to receive the diaphragm or member 33, which is adapted to be screwed lengthwise of the tubular portion of member 16, so as to regulate the extent to which the liquid may enter the tubular member 16. The outer end of tubular member 16 is preferably formed in the nature of a cap-portion 16 which screws into the end of the chamber 13, as previously described.

It is apparent from the construction that when the diaphragm member 33 is moved lengthwise of member 16, the liquid-receiving space or chamber Within valve 15 will either be increased or diminished, depending upon the direction in which diaphragm member 33v is moved. For example, if diaphragm member 33 be moved to the extreme inner or right-hand end of member. 16, the valve will have greater capacity than would be the case if the member'33 was left at the point indicated in Fig. 6, so that each operation of the valve will dispense its maximum quantity of liquid. On the other hand, if diaphragm 33 is screwed to the extreme outer or left-handend of tubular member 16, the compartment or liquid-receiving space within the tubular member, as well as that of the valve, will to that extent be lessened or shortened, so that a lesser quantity of liquid will be dispensed with each operation of the valve. i

In the operation of our dispensing device, the liquid-container or bottle 26 is inserted in the barrel or receiving-portion 20 in an inverted manner, as shown in the drawings, the mouth of the bottle resting upon the cushioning means or washer 28. Except for the quantity of liquid which may spill during the insertion of the bottle, none of the liquid will flow into container 20, be-

hea set) eause the mouth of the bottle is flush with the washer or member 28 and air cannot pass into the bottle except through the valve 15. In view of the fact that a small quantity of liquid will spill intothe holderportion 20, we prefer to extend the air-tube 31, as shown in Fig. 3, so as to prevent the latter being sealed by the spilled liquid within holder 20. The manipulator will then rotate valve 15 into the position shown in Fig. 3, so asto bring port 18 into register with passage or port 19, and thereby establish communication with the interior of the bottle or container 26 by means of the extension or tube 29. The arcuate port 21 will also establish communication be tween the interior of valve 15 and the airspace or chamber within holder 20 by means of tube 31 and port or passage 22. With the valve in this position, air from within valve 15 will pass upward through port or passage 19 and tubular member 29 into the bottle, thereby allowing the liquid to flow from the bottle into valve .15. The liquid flowing into valve 15 will force surplus air out of the valve 15 through port 22, until the liquid has filled the liquid-receiving space of valve 15, and closed port or passage 22. As soon as the air-port or passage 22 has been sealed by the liquid, further flow of liquid from the bottle will be prevented, because of the inability of a, further quantity of air entering the bottle or container 26. The construction of tubular member 29 is such that any extraneous matter, within the bottle or container 26 of such dimensions as would aflect the valve, will be prevented from passing through tubular member 29;.

at the same time the construction of the tubular member will cause large air-bubbles passing upward to become broken or finely divided, thereby not only causing a better action of the device, but also more thoroughly aerating the liquid. When the valve 15 is filled, the manipulator will rotate the valve so as to bring port 17 into register with port or passage 12, at which time port 18 will be moved out of register with port or passage 19, thus preventing any further liquid entering the valve during the withdrawal of the liquid from the valve. By reason of the elongation of port 21, constant .communication with air-port or passage 22 will be maintained during rotation of the valve. to bring port. 17 into register with port or passage 12. The admission of air will, of course, permit the liquid to flow out of valve 15 through port or passage 12 and be discharged through spout 27. The shoulders 15 in the cylindrical wall of valve 15, are arranged apart a distance corresponding with the distance between ports 17 and 18, so that the lug or shoulder 23, arranged within the chamber 13, will prevent too great a rotation of valve 15. It is evident from the construction shown and described that a uniform quantity of liquid will be given with each operation 'of the valve. The quantity can be increased or diminished by positioning diaphragm member 33 to the desired point, so.that the quantitydispensed will not be controlled by or at the will of the operator.

We have shown and described what we believe to be the simplest and best form of our invention, but the same may be altered in certain respects without, however, departing from the spirit of our invention, and We do not wish to be understood, therefore, as limiting ourselves to the exact construction shown and described.
