In 1928 he formed the Coleman Auto Spring Suspension Co. Ltd. The purpose of the company was to promote the Coleman patents and generate revenue from the sales of licenses. With the death of his father, he inherited the Barker House Hotel on Queen Street and the Summer Resort at Kilarney Lake. During the great depression, all of Coleman’s income from patent royalties was spent to maintain the hotel and resort.

Coleman’s invention can still be seen on most cars and small trucks without significant changes from the inventor‘s original design.
