In 1922 Lindeman & Sons, with a reported capacity 3,000 pianos per year and which still owned H. & S. G. Lindeman, were purchased from Wanamaker's, as was the much larger Emerson Piano Co. of Boston by J. H. Shale, treasurer of A. B. Chase of Chicago, and J. H. Williams, of the Knabe Warerooms, Inc, of Baltimore, who formed a holding company known as United Piano Corporation, of Norwalk Ohio, which was capitalized for $1,000,000 and which operated A. B. Chase, along with the two Lindeman firms and soon introduced the Celco reproducing player piano mechanism. In 1924 all of the divisions were moved to a 110,000 square foot factory in Norwalk, Ohio.
