An ice resurfacer is a vehicle or hand-pushed device used to clean and smooth the surface of an ice sheet, usually in an ice rink. The two major North American manufacturers are Resurfice Corporation, which sells Olympia-brand machines, and Frank J. Zamboni & Company and other brands include the Okay Elektra, an electric ice resurfacer made in Canada in the province of Quebec. The first ice resurfacer was pioneered and developed by American inventor and engineer Frank Zamboni in 1949 in the city of Paramount, California. Zamboni /zæmˈboʊni/ is an internationally registered trademark.
The first ice-resurfacer was the brainchild of Frank J. Zamboni, who was originally in the refrigeration business. He provided services to businesses such as dairy farms and produce vendors. Zamboni created a plant for making ice blocks that could be used in refrigeration techniques. As the demand for ice blocks waned, he looked for another way to capitalize on his expertise with ice. His idea of the Zamboni however didn't come to him right away.
In 1939, Zamboni created the Iceland Skating Rink in Paramount, California. In order to resurface the skating rink, 3 or 4 workers had to scrape, wash, and squeegee the ice. A thin layer of water was then added for the fresh ice. This process was extremely time consuming, and Zamboni wanted to find a more efficient way to resurface the ice.
From 1942 to 1947, he tried, fruitlessly, to develop a vehicle that could cut down on resurfacing time. In 1947, he decided on a machine that would shave, wash and squeegee the ice. This machine was mounted on an army surplus vehicle chassis. A blade was mounted on the machine, which would shave the ice; the ice would then receive a thin layer of water creating a smooth sheet of ice. The prototype had a tank that held the ice shavings, which were carried to the tank via a conveyor belt. This machine was powered by a Jeep engine and transmission. Zamboni abandoned this model in late 1947 because of deficiencies with the blade and handling.
