Abstract
Abstract An ice piece dispenser comprising a receptacle for storing ice pieces and including a front plate having a discharge opening therein. There is provided a dispenser horizontally supported in the receptacle and includes a rotatable feed section having an inlet end and a discharge end with a central axle therebetween, the feed section comprising a cylindrical collar adjacent the front plate and a double bladed screw auger within the collar forming two helical passages. The blades of the screw auger extend from the central axle to the collar and are spaced rearwardly from the front plate with the trailing edge of each blade being curved rearwardly between the axle and collar sufficiently to prevent ice pieces being wedged between the front plate and the blades during rotation of the feed section. A wire auger which is rotatably driven is secured to the feed section for rotation in unison therewith.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
171 words
An ice piece dispenser comprising: a receptacle for storing ice pieces and including a front plate having a discharge opening therein; dispensing means horizontally supported in said receptacle and including, a rotatable feed section having an inlet end and a discharge end and a central axle, said feed section comprising two separate bodies mated together and having a cylindrical collar adjacent the front plate and a double bladed screw auger forming two helical passages, said blades extending from the central axle to the collar with the junction of the blades and central axle being spaced rearwardly from the front plate and the trailing edge of each blade being curved rearwardly in the direction of the inlet end of the feed section between the axle and collar sufficiently to prevent ice pieces being wedged between the front plate and the blades during rotation of the feed section, a rotatable wire auger secured to the rotatable feed section, and drive means engaging the rotatable wire auger at the end opposite the feed section.
Claim 2
Dependent Claim
171 words
An ice piece dispenser comprising: a receptacle for storing ice pieces and including a front plate having a discharge opening therein; dispensing means horizontally supported in said receptacle and including, a rotatable feed section having an inlet end and a discharge end and a central axle, said feed section comprising two separate bodies mated together and having a cylindrical collar adjacent the front plate and a double bladed screw auger forming two helical passages, said blades extending from the central axle to the collar with the junction of the blades and central axle being spaced rearwardly from the front plate and the trailing edge of each blade being curved rearwardly in the direction of the inlet end of the feed section between the axle and collar sufficiently to prevent ice pieces being wedged between the front plate and the blades during rotation of the feed section, a rotatable wire auger secured to the rotatable feed section, and drive means engaging the rotatable wire auger at the end opposite the feed section.
Claim 3
Dependent Claim
