How the Zamboni Got Invented in a Paramount Skating Rink
Frank Zamboni spent nine years engineering the first ice resurfacer so his rink could stop sending three men out with scrapers.
Before 1949, clearing an ice rink meant three to five men with scrapers, squeegees, and hoses working in sequence. A scraper shaved a thin layer of bad ice. A squeegee swept away the debris. A pair of hoses laid down warm water to freeze into a new surface. The whole cycle took 60 to 90 minutes, during which skaters stood at the boards and the rink made no money.
Frank Zamboni, a refrigeration engineer in Paramount, California, ran the Iceland ice rink with his brother Lawrence. He spent the 1940s building a machine that would do all three jobs on one pass. His first prototype, Model A, worked in 1949. Model E, licensed and manufactured starting in 1964, became the standard machine that still dominates rinks today.
The mechanism is straightforward. A horizontal blade shaves a sliver off the surface and deposits it into a holding tank. A water jet rinses grit out of the surface grooves. A smooth-bottomed tank of warm water pours out behind, guided by a felt squeegee, depositing a thin layer that freezes in about a minute. The driver sits up high for visibility and steers the machine in a tight figure-eight pattern.
Zamboni registered the trademark in 1953 and defended it aggressively. 'Zamboni' remains a legally protected trade name — unlike 'thermos,' 'escalator,' and 'aspirin,' which lost trademark status because their makers tolerated generic use. The proper generic term is 'ice resurfacer.' Nobody says it.
The Zamboni Company has built more than 11,000 machines over its history. It is still family-owned, still headquartered in Paramount. Frank died in 1988. His sons and grandsons run it.
