Dispensing apparatus for a plurality of liquids to make a rainbow cocktail or the like

Claim 1

In a dispensing apparatus for a plurality of liquids to make a rainbow cocktail, the combination of a frame, a horizontally positioned turret mounted for rotation about an upright axis on the frame, a plurality of independent containers for liquids, each provided with an opening to discharge downwardly, valve structures carried in angularly spaced relation on the turret, one for each container each valve structure comprising a hollow body member having an internal partition forming an upper liquid receiving chamber and a lower measuring chamber of predetermined capacity; said partition being provided with an opening therethrough making said chambers communicative; said upper chamber having a top opening; said lower chamber having a bottom opening, an upright valve stem positioned through the opening in the partition; said stem extending into the upper chamber and downwardly out of the bottom opening of the lower chamber and outwardly of said body; the openings through which said valve stem is positioned being larger than the cross section of said stem, a first valve element carried on the portion of said stem which extends into the upper chamber, adapted to close the opening in the partition when the said stem is moved downwards, a second valve element carried on the portion of said stem which is downwardly outwardly of the valve body, adapted to close said bottom opening when said stem is moved upwards, means holding the stem for longitudinal sliding movement on the valve body, spring means biasing said stem downwardly to a normal rest position where the opening in the partition is closed and said bottom opening is open, means communicatively connecting the discharge openings of the said containers with the said upper openings of said valve structures respectively, whereby liquids in said containers will discharge only through said upper openings respectively; each valve body being provided with a vent leading from the upper region of the upper chamber and opening in the top region of the body member, and also with a vent leading from the upper region of the lower chamber and opening in the top region of the body member, a cam fixed on the frame, adapted to intercept the lower end of each valve stem in succession, one at a time, as the turret is rotated, and push upwards the valve stem passing it, whereby the opening in the partition of the valve structure passing the cam, is opened and its bottom opening is closed while the stem is contacted by the cam; the spring means associated with such moved stem, automatically returning such valve stem to its normal rest position when such valve stem leaves the cam, whereupon any liquid in the lower chamber said stem is associated with, will be discharged through the bottom opening, means to hold a glass in position on the frame, to receive the liquid discharged through said bottom opening, and guide means on the frame, positioned at the mouth region of the glass, adapted to direct such discharge against the inner surface of the glass.
