He is best known for making an ice resurfacer. This is a machine that makes ice smooth again.

In 1940, Frank opened a large ice rink. It was called Iceland Skating Rink. At first, the rink was open to the air. Later, a dome was added to cover it. To make the ice, pipes under the floor flooded the surface with water and chemicals. This caused ripples in the ice. Frank found a way to fix this problem. He even got a patent for his new idea.

Before his machine, fixing the ice was hard work. It took five people and 90 minutes. In 1947, Frank made a machine to help. It used one person and only 15 minutes!

The machine uses a sharp blade to shave the ice. It collects the shavings and washes the surface. Then, it spreads a thin coat of fresh water. Many people love to watch the machine work at hockey games.
