Hart and Cooley Revenue and Competitors

Howard Stanley Hart was an entrepreneur, inventor, industrialist, and builder. One of Hart's many inventions was a steel heating register that proved superior to traditional heavy cast-iron models. In partnership with Norman P. Cooley, Hart established the Hart & Cooley Manufacturing Company in New Britain, Connecticut in 1901. This new company became the first in the nation to manufacture warm-air registers from stamped steel, a product line that gained almost instant success. In the Roaring Twenties, Hart & Cooley expanded their register business to Holland, Michigan, where they opened a manufacturing facility. By the early 1930s, Hart & Cooley was the world's largest producer of warm-air registers. The Holland plant grew and soon featured unmatched facilities for research and manufacturing.
