Abstract
Abstract A reservoir having an inlet end and an outlet is disposed in a housing to receive ice from a chipped ice manufacturing device at its inlet end. A chamber is formed exteriorly of the reservoir at the outlet thereof, and a power operated conveyor is positioned within the lower end of the reservoir to deliver chipped ice from the reservoir to the chamber. Electrically operated controls are connected to terminate operation of the power operated conveyor responsive to a predetermined operation of the conveyor to dispense a desired amount of chipped ice, and a vane pivotally connected to the conveyor is disposed within the chamber to sweep therethrough during operation of the conveyor and positively displace and dispense ice within the chamber laterally outwardly through an opening formed in the lowermost portion of the side wall of the chamber during operation of the conveyor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
An ice-dispensing device comprising: a. an ice supply reservoir; b. an ice dispensing chamber communicating with said reservoir, said chamber having an outlet formed in a lowermost portion thereof; c. power operated means for moving ice from said reservoir to said chamber; d. ice-dispensing means located in said chamber and operable to move from a first position, wherein said ice-dispensing means closes said outlet, to a second position wherein said icedispensing means sweeps through said chamber positively displacing ice therefrom to eject the ice through said outlet, and back to said first position; and e. control means including circuit means connected to terminate operation of said power operated means responsive to a predetermined operation of said power operated means.
Claim 2
Dependent Claim
119 words
An ice-dispensing device comprising: a. an ice supply reservoir; b. an ice dispensing chamber communicating with said reservoir, said chamber having an outlet formed in a lowermost portion thereof; c. power operated means for moving ice from said reservoir to said chamber; d. ice-dispensing means located in said chamber and operable to move from a first position, wherein said ice-dispensing means closes said outlet, to a second position wherein said icedispensing means sweeps through said chamber positively displacing ice therefrom to eject the ice through said outlet, and back to said first position; and e. control means including circuit means connected to terminate operation of said power operated means responsive to a predetermined operation of said power operated means.
Claim 3
Dependent Claim
119 words
An ice-dispensing device comprising: a. an ice supply reservoir; b. an ice dispensing chamber communicating with said reservoir, said chamber having an outlet formed in a lowermost portion thereof; c. power operated means for moving ice from said reservoir to said chamber; d. ice-dispensing means located in said chamber and operable to move from a first position, wherein said ice-dispensing means closes said outlet, to a second position wherein said ice-dispensing means sweeps through said chamber positively displacing ice therefrom to eject the ice through said outlet, and back to said first position; and e. control means including circuit means connected to terminate operation of said power operated means responsive to a predetermined operation of said power operated means.
Claim 4
Dependent Claim
119 words
An ice-dispensing device comprising: a. an ice supply reservoir; b. an ice dispensing chamber communicating with said reservoir, said chamber having an outlet formed in a lowermost portion thereof; c. power operated means for moving ice from said reservoir to said chamber; d. ice-dispensing means located in said chamber and operable to move from a first position, wherein said ice-dispensing means closes said outlet, to a second position wherein said ice-dispensing means sweeps through said chamber positively displacing ice therefrom to eject the ice through said outlet, and back to said first position; and e. control means including circuit means connected to terminate operation of said power operated means responsive to a predetermined operation of said power operated means.
Claim 5
Dependent Claim
77 words
The structure of claim 1 in which said power operated means comprises: a. an upwardly opening channel formed in the bottom wall of said reservoir having a longitudinal axis which extends generally radially of said reservoir; b. a screw conveyor extending longitudinally within said channel; c. a shaft rotatably mounting one end of said conveyor at one end of said channel; and d. the other end of said screw conveyor and said channel terminating at said outlet.
Claim 6
Dependent Claim
51 words
The structure of claim 2 in which said reservoir includes a cylindrical side wall haVing a vertical axis and an upwardly opening cross-sectionally V-shaped bottom wall, said channel being formed in one leg of said V-shaped bottom wall and defining a liquid outlet formed therein generally at the lowest portion thereof.
Claim 7
Dependent Claim
50 words
The structure of claim 2 in which said means forming a chamber comprises a cylindrical wall extending from said reservoir at said outlet on an axis extending coaxially with respect to the axis of said screw conveyor, and an end wall closing the axial outer end of said cylindrical wall.
Claim 8
Dependent Claim
55 words
The structure of claim 2 in which said power operated means includes an electrical motor mounted to impart rotation to said shaft of said screw conveyor and in which said control means includes switch means and switch actuating means carried by said shaft mounted to engage said switch means upon each revolution of said shaft.
Claim 9
Dependent Claim
70 words
The structure of claim 5 in which said conveyor means further includes: a. an elongated shaft extending vertically upwardly coaxially within said reservoir; b. said shaft being mounted for rotation in said bottom wall of said reservoir; c. a paddle element carried by said shaft for common rotation therewith; and d. power means independent of said electrical motor for said screw conveyor for imparting said rotation to said vertical shaft.
Claim 10
Dependent Claim
133 words
The structure of claim 4 in which said cylindrical side wall has formed therein a slot which is circumferentially disposed from said opening and in which said means for positively dispensing ice from said chamber includes: a. a blade-like element having one end thereof pivotally secured to said one end of said screw conveyor adjacent the periphery thereof; b. the other end of said blade-like element extending through said slot; and c. said blade-like element being movable during each revolution of said screw conveyor from a first position wherein said blade closes said opening to a second position wherein said pivotal connection of said blade is adjacent said slot and said blade-like element is positioned substantially exterior of said chamber and back to said first position wherein said blade-like element closes said opening.
Claim 11
Dependent Claim
59 words
The structure of claim 7 in which said blade-like element and said slot each has a dimension generally equal to the axial dimension of said chamber and in which that portion of said blade-like element adjacent said opening during said first position has an arcuate conformation conforming generally to the shape of the cylindrical side wall of said chamber.
Claim 12
Dependent Claim
41 words
The structure of claim 1 in which said ice dispensing means includes a blade-like element connected to said conveyor means and adapted to sweep through said chamber to dispense ice therein through said opening thereof during operation of said conveyor means.
