Following the collapse of the family business, Coon went into business for himself purchasing a store building in Philadelphia. In March 1915, Coon rented a closed cheese factory in
Edwards, New York hiring W.E Walker as a cheesemaker, and opening for business on April 1. By this time Coon was operating under the business name E.W. Coon & Co, and was among New York's best known cheese merchants having established a national reputation as a purveyor of Yankee cheeses, and having extensive business exporting cheese to England and Italy. In June 1915, Coon further expanded his business, purchasing the Cleveland seed warehouses in
Cape Vincent, New York, and remodelling them for use as a storage plant for cheese and butter. The remodelling of the plant was done in a novel way, differing from that of traditional refrigeration techniques by making use of a large number of tiles to make the storage facility resemble as near as possible the hold of an ocean liner. Coon was subsequently involved in long
litigation involving 11 insurance companies, eventually recovering $120,000. and the other formerly the Falk American Potato and Flour Corporation, described as the "largest cheese storage plant in the state of Wisconsin" Under the
business name Acme Cheese Development and Storage, the former Falk site was transformed, and employed between 15 and 25 people for both storing cheese and processing cheese. Cheese processed at the facility was done so in line with Coon's 1926 patent and produced a cheese described as taking on a "sharp, nippy taste which improves its quality". The cheese was marketed as "COON-Sharp Cheese". under the management of R.T. Gillespie. before their acquisition of Coon's company. This plant continued to make cheese according to the "Coon patented" "cave-cure" treatment of cheese , and continued its operation after Gillespie's passing on 1936. At one time, Coon operated 14 cheese factories in
New York State (in existence 1928–1930). In 1928, Coon was made an offer by the
Kraft-Phenix Cheese Company (in existence 1928–1930 Kraft-Phenix paid $732,983.25 for the business and Coon was kept on as manager until his death in 1934. ==Cheese-making patent==
