Storage and ice dispensing system for ice in flake or particle form
First Claim
1. A particle-ice dispenser for an ice storage bin comprising:
- a rectangularly shaped frame pivotally supported within a bin at one end and suspended at its opposite end for swinging up and down movement about the pivoted end both above and below horizontal by about 30°
,driven screw flight augers supported by the frame therebelow and extending from the pivoted end toward the suspended end,wall means in said bin below the frame pivoted and separating the bin into ice storage space below the augers and ice discharge space past the pivoted end of the frame, anda mechanical oscillating drive operatively associated with the pivoted frame end for oscillating said auger flights lengthwise thereof while the augers are driven for ice dispensing.

Abstract
A storage and dispensing system for ice in flake or particle form is disclosed utilizing a storage bin with driven screw augers extending outwardly over and above an ice storage space, the discharge end of the screw augers being pivotally mounted at the discharge end thereof with the other end of the augers being flexibly suspended for arcuate movement about the pivoted end to a position above the stored ice and being lowered into contact with the stored ice for auger dispensing, the auger being lowered as ice is discharged; the auger dispenser is oscillatable lengthwise during dispensing drive and is equipped with ice cutting blades on the outer edges of the screw flights and at the free end of such flights so as to ensure cutting a path through the particle ice as the conveyor device descends through the stored ice for dispensing purposes.

4. A storage and dispensing device for ice in flake and particle form, comprising:
-
a three-dimensional bin having a partial bin-height interior wall dividing the bin interior into a relatively large ice storage space and a relatively small ice discharge space across one end of the bin interior, an ice inlet in the bin over the storage space for gravity ingress of ice, an ice outlet in the bin discharge space for egress of ice dispensed from the storage space over the top of the interior wall, a helical screw auger conveyor having a pair of driven counter-rotating auger flights extending outwardly over the storage space from the top of said interior wall, frame means including bearing supports for the auger flights, said frame means being pivotally supported at the top of the interior wall, means for raising the frame and conveyor about said pivotal support to a starting position above the stored ice and lowering same so that said augers may contact ice in the storage space and convey same to the discharge space, and means for oscillating the auger flights lengthwise thereof an amount at least equal to the length of said bearing supports for the auger flights so that the augers may contact ice in storage below said bearing supports. - View Dependent Claims (5, 6, 7, 8)

9. A flake and particle ice storage and dispensing device, comprising:
-
a fully insulated three-dimensional bin having an interior partial bin-height wall dividing the bin interior into relatively large storage space and relatively small discharge space, bin ingress means for gravity ice flow into the storage space, bin exit means for ice dispensed from said discharge space, an ice excavator including; a frame pivoted at one end just above the top of said partial-height wall, and extending outwardly over the ice storage bin space, flexible means suspending the opposite frame end from the top of the bin between an upper position out of contact with stored ice and lower positions engaging such ice, at least one pair of reversibly driven counter-rotating screw augers having bearing supports secured to and suspended below said frame, said augers being swingable with the frame about said pivot and substantially filling said storage space in plan when lowered to horizontal position, and means for oscillating said frame and augers longitudinally of the augers an amount at least equal to length of bearing supports for the augers, said augers being elevated at the dividing wall to dispense ice thereover into the discharge space, said augers spreading incoming ice away from the wall when rotated one direction and augering ice from storage into the discharge space upon reverse rotation.

10. A day tank flake ice dispensing mechanism, comprising:
-
a rotary screw auger conveyor having at least two powered counter-rotating flights extending side by side across an ice storage bin, a frame above the flights having depending bearing housings supporting the flights, said frame having a pivoted support at one ice discharge end of the augers and being suspended at the opposite end for arcuate swinging about said pivoted support in up and down movement of the frame and supported auger flights between an upper position out of contact with stored ice and lower positions engaging such ice, and means for oscillating the frame and auger flights as a unit endwise of the flights during ice dispensing, the maximum oscillation being at least equal to the length of said bearing supports measured longitudinally of the auger flights. - View Dependent Claims (11, 12)
