Abstract
Improved apparatus is disclosed for supporting the cutting teeth on the periphery of a rotating cylindrical drum ice cutter affixed to a floating arctic structure. The cutting teeth are individually removably affixed to brackets which extend spirally (either continuously or in segments) around the drum periphery and are supported in spaced relationship radially outwardly therefrom by very sturdy struts. Several benefits are obtained with this configuration: (1) hydrodynamic drag is minimized; (2) the teeth-support structure can be made more rugged than individual ones for each tooth; (3) the teeth can be configured for a minimum of replaceable material at the cutting tips; (4) more free volume is available around the drum periphery for disposal flow of disaggregated material and (5) tooth spacing can be readily adjusted for optimum performance according to requirements.
