Abstract: An ice level sensor for a flake-ice icemaker of the type having an electrically grounded rotary shaft for scraping ice from a refrigerated surface into an underlying ice bin has a contact plate insulated connected to a control circuit, a metallic sensing arm suspended from and electrically connected to the shaft for sweeping a path in the ice bin, the sensing arm moving against the plate on contact with accumulated ice thereby completing an electrical circuit through the drive shaft and causing the control circuit to stop the icemaker.

Abstract: An improved flake ice making machine is disclosed wherein flake ice is broken away from a submerged refrigerated surface by a rotating auger. A tank surface opposite the refrigerated surface has screw thread guides affixed to it which cooperate with the rotating auger to lift ice flakes over the tank wall and into an ice receiving channel encircling the tank wall. A sweeper arm rotates with the auger and sweeps the ice in the channel towards a discharge opening. Pressure sensitive switch means are connected for stopping rotation of the auger in response to an excessive accumulation of ice in the event of blockage of the discharge opening. The auger is supported only to a drive shaft extending through the evaporator so that there are no submerged bearings or bearing surfaces.
