Abstract
Abstract An ice dispensing machine having an insulating casing with a platform adjacent the bottom for supporting a mass of flaked ice with a rotatable impeller mounted adjacent the bottom of the mass of ice to shave the ice therefrom and direct such ice to a vertically extending conveyor for carrying the ice upwardly to a discharge spout with a receptacle actuated lever for starting the operation of the impeller and conveyor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
204 words
A dispensing machine comprising an upright cylindrical housing having a conical material receiving platform adjacent the bottom of said housing, means at the upper portion of said housing for supplying material to said conical platform, an impeller rotatably mounted in said housing above and adjacent to said platform for contact with the lower portion of the mass of material therein, means to drive the impeller to loosen material from the bottom of the mass thereof, a screw conveyor extending upwardly above said housing and including a conveyor tube fixed in said housing and extending from adjacent the impeller, said conveyor tube having an entrance opening for material loosened by said impeller, a screw conveyor element in said tube, means to rotate said screw element, said conveyor tube having a discharge opening adjacent the upper end thereof, and means to cause the material to pass into the screw conveyor and outwardly from the material to pass into the screw conveyor and outwardly from the discharge opening said impeller comprising a pair of oppositely inclined blades mounted above said conical platform and sloped to conform thereto and serving to direct material received from said upper material supply means to the entrance opening of said conveyor tube.

The invention according to claim 4 in which a reversely pitched screw section is fixed to the conveyor tube upwardly of the deflector plate.
Claim 8
Dependent Claim
21 words
The invention according to claim 4 in which a screw element is fixed to said conveyor tube adjacent said deflector plate.
Claim 9
Dependent Claim
42 words
The invention according to claim 1 in which the screw conveyor element and the impeller are mounted for rotation on a coincident vertical axis and the supporting platform flares upwardly and outwardly and the arms of the impeller extend outwardly and upwardly.
Claim 10
Dependent Claim
46 words
The invention according to claim 1 in which the screw conveyor and impeller are mounted for rotation on parallel vertical axes and the impeller and platform extend outwardly and downwardly from the center thereof and the conveyor tube is mounted adjacent the periphery of the platform.
Claim 11
Dependent Claim
56 words
The invention according to claim 1 in which the axes of rotation of the impeller and of the screw conveyor are vertical and a cylindrical casing is provided extending upwardly from the platform for the ice material and a stabilizer blade extends radially inwardly from the housing to engage the ice material and prevent rotation thereof.
