A New York woman Hariette E Hodgson is credited with inventing a wheel shaped ice rescue frame eight or nine feet in diameter designed to save skaters and others who fall through ice. The device features an outer and inner ring linked by strong wires, with buoyant chambers possible in aluminum tubing, plus a rope system to reach and pull victims free.
