Abstract

An apparatus for dispensing a beverage by gravity feed from a container mounted in the outside of a door of a refrigerated cabinet, such as a home refrigerator, comprises a vented spout assembly for dispensing a beverage from a container by gravity feed at a substantially constant flow rate in combination with an actuation mechanism mounted in the door of the refrigerator. The vented spout assembly includes a valve assembly collar connectable to a discharge opening in the container, a vent tube extending from a location in the collar to a location in the container spaced from the discharge opening, the vent tube defining a vent passage therethrough. The collar has a discharge wall with a liquid discharge port therethrough. A rotary valve element is mounted for rotation in the discharge wall between OPEN and CLOSED positions. The rotary valve has a liquid discharge conduit and a vent conduit therethrough alignable with the discharge port and the vent passage, respectively, when in the OPEN position of the valve element, a spout extends from the liquid discharge conduit of the rotary valve element and an actuation lever extends from the rotary valve element for engagement with the actuation mechanism mounted in the door.

Claims

1. A vented spout and actuator assembly for dispensing a beverage from a container by gravity feed at a substantially constant flow rate comprising:

a valve assembly collar connectable to a discharge opening in the container;

a vent tube extending from a location in said collar to a location in said container spaced from said discharge opening, said vent tube defining a vent passage therethrough;

said collar having a discharge wall with a liquid discharge port therethrough;

a rotary valve element mounted for rotation in said discharge wall between open and closed positions, said rotary valve element having a liquid discharge conduit and a vent conduit therethrough, alignable with said liquid discharge port and said vent passage, respectively, when in said open position;

a spout extending from the liquid discharge conduit of said rotary valve element; and

an actuation lever separate from said spout extending from said rotary valve element for rotating said valve element between said open and closed position; and

actuator means for said lever and having a first end for engagement by a beverage receptacle at a location spaced from said spout and a second end connected to said actuation lever, whereby said rotary valve element is movable between said open and closed positions by movement of the beverage receptacle for dispensing said beverage.

2. The vented spout assembly of claim 1 wherein said rotary valve element is cylindrical.

3. The assembly of claim 1 wherein said actuation lever is oriented at an angle of substantially 90°

relative to said spout.

4. The assembly of claim 1 wherein said actuation lever depends vertically from said rotary valve element in said closed position and horizontally therefrom in said open position.

5. The assembly of claim 1 wherein said actuator means comprises an actuation pad at said firs end and being aligned with said spout, an L-shaped connector having a leg thereof extending outwardly from the actuation pad and a second leg extending at a right angle therefrom, said second leg being connected to reduction gear means, an actuation shaft extending outwardly from said reduction gear means, said actuation shaft having an eccentric portion including a slotted connector for receiving said actuation lever therein, whereby movement of the actuation pad orthogonally pivots the eccentric portion of the actuation shaft and the slotted connector to thereby move the actuation lever orthogonally to the open or closed positions of the valve element.

6. An apparatus for dispensing a beverage by gravity feed from a container mounted in the outside of a door of a refrigerated cabinet comprising:

(a) a vented spout assembly for dispensing a beverage from a container by gravity feed at a substantially constant flow rate including,

a valve assembly collar connectable to a discharge opening in the container;

a vent tube extending from a location in said collar to a location in said container spaced from said discharge opening, said vent tube defining a vent passage therethrough;

said collar having a discharge wall with a liquid discharge port therethrough;

a rotary valve element mounted for rotation in said discharge wallbetween open and closed positions, said rotary valve element having a liquid discharge conduit and a vent conduit therethrough alignable with said liquid discharge port and said vent passage, respectively, when in said open position;

a spout extending from the liquid discharge conduit of said rotary valve element; and

an actuation lever extending from said rotary valve element for moving said valve element between said open and closed positions; and

(b) actuation means mounted in said door, having a first end for engaging a receptacle to be filled with the beverage at a location spaced from the spout and a second end connectable to said actuation lever, whereby said rotary valve element is movable between said open and closed positions by the receptable to be filled.

7. The apparatus of claim 6 wherein said actuation means comprises an actuation pad at said first end vertically aligned with said spout in a recess in said door, an L-shaped connector having a leg thereof extending horizontally from the actuation pad into a location in the door adjacent said recess and a second leg extending vertically in said door, said second leg being connected to reduction gear means, an actuation shaft extending horizontally from said reduction gear means into said recess in the door, said shaft having an eccentric portion including a slotted connector for receiving said actuation lever, whereby movement of the actuation pad orthogonally to the outside surface of said door pivots the eccentric portion of the actuation shaft and the slotted connector to thereby move the actuation lever orthogonally of the outside surface of the door to the open or closed positions of the valve element.

8. The apparatus of claim 6 further including agitator means in the container and oscillator means in said door, said agitator means being connectable to said oscillator means for being oscillated thereby.
