Abstract
Abstract An ice dispenser for use with an ice maker in a freezerrefrigerator or the like employs a lift wheel with a series of compartments about its periphery. The compartments lift pieces of ice from a reservoir, into which the ice maker empties, and discharge them piece-by-piece through an elevated outlet. The partitions between the compartments of the wheel are formed by blades of resiliently flexible material which operate against the inner surface of a housing enclosing the wheel to reduce noise and breakage of ice. The shape of the upper portion of the housing and the resiliently flexible blades also cooperate to help discharge the ice pieces through the outlet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
303 words
In an ice dispenser for use with refrigeration apparatus, the dispenser having an ice reservoir effective to receive pieces of ice from an ice maker, the reservoir including an upstanding front wall, a rear wall and a bottom wall interconnecting the front and rear walls, a power drivable ice lift wheel mounted outside of the reservoir front wall for rotation in one direction about an axis extending forwardly from said front wall, a lift wheel housing mounted forward of the reservoir front wall and including a front wall and a peripheral wall enclosing the lift wheel, a plurality of compartments for holding ice pieces disposed peripherally about the lift wheel, the compartments being formed by the reservoir front wall, the housing front and peripheral walls and a plurality of spaced compartment partition walls extending between the lift wheel periphery and the housing peripheral wall and transversely of and between the reservoir and housing front walls, the compartments opening rearwardly toward the reservoir front wall and forwardly toward the housing front wall, means in the reservoir effecting movement of ice pieces therein toward the reservoir front wall, an ice inlet through the reservoir front wall effective so that the ice moving means also impels pieces of ice in the reservoir through the ice inlet into lower ones of the lift wheel compartments during said rotation of the wheel, and an ice outleT through the housing front wall communicating with upper ones of the lift wheel compartments during said rotation of the wheel, the lift wheel compartments being effective to transport ice pieces received therein from the ice inlet up to the ice outlet and to discharge the same therethrough during said rotation of the wheel, the improvement wherein said partition walls comprise blades formed of resiliently flexible sheet material carried by the lift wheel.
Claim 2
Dependent Claim
303 words
In an ice dispenser for use with refrigeration apparatus, the dispenser having an ice reservoir effective to receive pieces of ice from an ice maker, the reservoir including an upstanding front wall, a rear wall and a bottom wall interconnecting the front and rear walls, a power drivable ice lift wheel mounted outside of the reservoir front wall for rotation in one direction about an axis extending forwardly from said front wall, a lift wheel housing mounted forward of the reservoir front wall and including a front wall and a peripheral wall enclosing the lift wheel, a plurality of compartments for holding ice pieces disposed peripherally about the lift wheel, the compartments being formed by the reservoir front wall, the housing front and peripheral walls and a plurality of spaced compartment partition walls extending between the lift wheel periphery and the housing peripheral wall and transversely of and between the reservoir and housing front walls, the compartments opening rearwardly toward the reservoir front wall and forwardly toward the housing front wall, means in the reservoir effecting movement of ice pieces therein toward the reservoir front wall, an ice inlet through the reservoir front wall effective so that the ice moving means also impels pieces of ice in the reservoir through the ice inlet into lower ones of the lift wheel compartments during said rotation of the wheel, and an ice outleT through the housing front wall communicating with upper ones of the lift wheel compartments during said rotation of the wheel, the lift wheel compartments being effective to transport ice pieces received therein from the ice inlet up to the ice outlet and to discharge the same therethrough during said rotation of the wheel, the improvement wherein said partition walls comprise blades formed of resiliently flexible sheet material carried by the lift wheel.
Claim 3
Dependent Claim
59 words
The ice dispenser of claim 1 wherein each of the blades includes a rearward edge portion adjacent the reservoir front wall and a forward edge portion in resilient contact with the housing front wall, the forward edge portion being disposed in trailing relation to the rearward edge portion with respect to said direction of rotation of the lift wheel.
Claim 4
Dependent Claim
97 words
The ice dispenser of claim 2 wherein the upper portion of the housing peripheral wall is formed with a lesser radius at two peripherally spaced locations to provide a pair of corner portions disposed in leading and trailing relation to each other on said wall with respect to said direction of rotation of the lift wheel, the ice outlet being disposed in the housing front wall at the leading one of said corner portions, the blades having outer end portions in resilient contact with the peripheral wall of the housing during said rotation of the lift wheel.
Claim 5
Dependent Claim
34 words
The ice dispenser of claim 3 wherein the housing peripheral wall maintains the outer end portions of the blades curvilinearly deflected in a direction opposite to said direction of rotation of the lift wheel.
Claim 6
Dependent Claim
76 words
The dispenser of claim 4 wherein the forward portion of the reservoir bottom wall is substantially concentric with the lift wheel, and the ice inlet comprises an arcuate opening in the reservoir front wall extending circumferentially with respect to the lift wheel from one side to the other of the bottom wall, said opening increasing in size from the leading to the trailing end thereof with respect to said direction of rotation of the lift wheel.
Claim 7
Dependent Claim
67 words
The ice dispenser of claim 5 including an ice piece deflector disposed at said trailing end of the ice inlet and operative upon pieces of ice partially therethrough into the lift wheel compartments, the deflector curving rearwardly from the reservoir front wall effective in conjunction with said rotation of the lift wheel to deflect said ice pieces the remainder of the way into the lift wheel compartments.
Claim 8
Dependent Claim
81 words
The ice dispenser of claim 5 wherein the ice moving means is power driven and comprises a helix extending between the reservoir front and rear walls, the forward end of the helix being operatively associated with the lift wheel for driving rotation thereof in said direction, and wherein the dispenser includes a source of power having an output shaft and means for releasably connecting the output shaft to the rear end of the helix for driving rotation thereof about its axis.
Claim 9
Dependent Claim
153 words
The ice dispenser of claim 7 wherein the releasable connecting means comprises a cylindrical driven member journaled for rotation in the rear wall of the reservoir, the rear end of the helix being fixed to the forward end of the driven member, the rear end of the driven member having an axially extending cylindrical recess therein opening through the rear wall of the reservoir, the inner peripheral surfaces of the recess being provided with driven dogs, and a drive member fixed to the power source output shaft for driving rotation thereby, the outer peripheral surface of the drive member being provided with drive dogs engageable with the driven dogs of the driven member for driving rotation thereof, the drive member being axially movable upon the power source output shaft for engagement and disengagement of the drive dogs with the driven dogs, and manually operable means for effecting said movement of the drive member.
