The shaft of the wooden-handled crank fits through the central openings in the crossbar and cream can into the square socket of the bearing attached at bottom on which the dasher also rests. Exterior bucket is pierced with two holes on opposite sides for salt-water overflow. Crossbar is stamped incuse "POLAR STAR / FREEZER / PAT FEB 15 - 1910 / NOTICE / USE ONLY ICE CREAM SALT / NEVER STOP TURNING / AFTER FREEZING BEGINS", while the cream can has "SCALD AFTER USING / DRY ON STOVE TO PREVENT RUST" around its opening. The wire-rimmed bucket is made in two pieces with folded, vertical seams and a folded-edge bottom. All components, except the bucket and cream can, are either cast or forged and detachable.
