EDWARD H. WEATHERHEAD, OF CLEVELAND, OHIO, ASSIGE'OR TO THE BISHOP- BABCOCK-BEOKER COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

LIQUID-DISPENSING DEVICE.

Specification of Letters Patent.

Patented Nov. 23, T915.

Application filed January 14, 1915. Serial No. 2,143.

and State of Ohio, have invented a new and useful Improvement in Liquid-Dispensing Devices, of which the following is a specificatlon, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is a liquid dispensing device adapted for use upon counters for the purpose of serving some particular beverage which will be contained in a bottle that can be received in the upper part of the apparatus.

The device also includes means for measuring out a predetermined amount of the liquid which will then be discharged upon every opening of the controlling valve. In such a device the essentials are simplicity and inexpensiveness, together with continuously tight valve action and it is to secure these objects that my improvements are directed.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain mecha nism embodying the invention, such disclosed means constituting, however, but one of va-.

rious mechanical forms in which the principle of the invention may be used.

In said annexed drawing :-Figure 1 is a front elevation partially in section of the device; Fig. 2 is a vertical transverse section showing the bottle-receiving casing and the controlling'valve, and Fig. 3 is a section on the line 33, Fig. 2, illustrating the valve.

In Fig. 1 there is shown a base plate 1 which will be set upon, or, if desired, attached to a counter. From either side of this base plate there extend supports 2 which are joined centrally above the base plate, being preferably formed integral. These supports are attachedto the base plate in any suitable manner.

At the juncture of the two supports there is formed a flat surface 5 upon which is set a casmg 6 which is attached to the supports by means of a bolt 7 extending through an aperture in the latter and held in place by means of a nut 8.

The casing 6 is formed with a flared chamber 9 in the upper end of the casing 6 adapted to receive an inverted bottle 10 which will be centered and held in place by means of pro ecting lugs or shoulders 11, and which will discharge into the lower portion of the casing 6, such lower portion terminating at the side of a second chamber 12 also formed in the casing and connecting with the main chamber by means of a port 13. The chamber 12 constitutes a measuring chamber in which a predetermined amount of liquid is held until the valve opens and discharges it, as will be described hereinafter. In the same side of the chamber 12 there is formed a second port 14; which consists of a discharge port and opens into a short spout 15. In all conduits through which syrup or another relatively heavy liquid passes, a considerable quantity of the same adheres to the conduit in the form of a film, which later comes down to the end in drops. It will be noticed that the discharge conduit 14: is very short and in this way I prevent the usual dripping which is so annoying in similar devices.

The chamber 12 is formed in the casing 6 and is closed by means of a plug 16 which is threaded into the side of the casing. Mounted in a boss 17 projecting inwardly from the opposite sideof the casing 6, is a valve stem 18 to which is attached an operating handle 19, such valve stem having at its inner end a disk 20 provided with two ports 21 and 22. Disposed against and attached to such disk 20 is a disk 32 of friction material, also provided with ports 23 and 2a, which are in register with the ports 21 and 22 in the disk 20. These ports are of the same size as the ports 13 and 14. which connect the chamber 12 with the chamber 10, and the discharge spout 15, respectively. The disks '20 and 32 are held snugly against the end of the chamber 12 by means of a spring 25 fitting around a boss 26 on the disk 20 and around a boss 27 on a small disk 28 provided with a rounded projection 29v fitting into a corresponding recess in a block of friction material which is set into the casing block 16. In this way the valve is maintained tight at all times, the tension of the spring being such that no liquid can leak around the disks and 32, through the ports.

The projecting shoulders 11 are preferably four in number, and are disposed at equal intervals around the inside of the casing 6, but one of these projections is continued down to the top of the chamber 12 and is hollowed out forming an air vent 31 leading from the chamber 12 to the chamber -10 above the lowerend of the bottle which is held therein.

The normal position of the valve is shown in'Fig. 2, in which position the discharge port is closedand the inlet port 23 is open,

since it is in register with the port 13 in the casing 6. The liquid-from the bottle then flows down and fills the chamber 12 and thus when the operating handle is moved to the right looking at Fig. 1, thus bringing the I 1 port 22 in register with the discharge port [siveand attractive. dispensing apparatus which does not have to be built into a counter and which may be used to receive a bottle of a certain type so that it cannot be put to "other uses than that for which it was originally'intended.

Other modes of applying the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the followbut must .pass

the principle of: my invention may be employed instead of,

ing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctlv claim as my invent1on:

1. In a liquid dispensing device, the c0mbination of a casing having a chamber adapted to receive an inverted bottle and a measuring chamber disposed laterally with respect to the lower end of said casing, such measuring chamber being provided with an air vent into such first-named chamber above the lower end of the bottle therein and having two ports in the side adjacent to such first named chamber, one of such opening thereinto and the other constituting a discharge port, and a disk pivotally mounted in such measuring chamber and provided with friction material on the side adjacent the port-containing side of such chamber, resilient means pressing said disk and such friction material snugly against such side, said disk being provided with ports adapted to register alternately with the two ports in such measuring chamber. 2. In a liquid dispensing device, the com- 'bination of a casing having a chamber adapted to receive an inverted bottle and being provided with inwardly projecting 7 guides to contact the bottle neck, said casing also containing a measuring chamber havlng a discharge port and a port leading to such first-named chamber, one of such guides extending'to such measuring chamber and being formed with an air vent passage therein for the same, and valve means controlling flow from such first-named chamber to such last-named chamber and also the discharge from such last-named chamber.

Signed by me, this 12th day of January,
