Abstract:
1. A method of making pieces of ice comprising the acts of: freezing water in a container into ice, wherein the container has an inner surface and an axial length from a first end of the container to a second end of the container; rotating a helically threaded shaft that extends through the container, wherein the ice surrounds and contacts the shaft and is engaged by a helical thread of the shaft for moving the ice in an axial direction with respect to the shaft toward a cutting member due to rotation of the helical thread that contacts the ice, wherein the shaft carries the cutting member being located at a surface of the ice that moves towards the cutting member by the rotating act; and shaving the ice by the cutting member, wherein the inner surface of the container diverges over the axial length of the container along a direction of the cutting member to improve movability of the ice toward the cutting member.
