The Mills Novelty Company, Incorporated of Chicago, Illinois was once a leading manufacturer of coin operated machines, including slot machines, vending machines, and jukeboxes, in the United States. Between about 1905 and 1930, the company`s products included the Mills Violano-Virtuoso and its predecessors, celebrated machines that automatically played a violin and, after about 1909, a piano. By 1944 the name of the company had changed to Mills Industries, Incorporated. The slot machine division was then owned by Bell-O-Matic Corporation. By the late 1930s, vending machines were being installed by Mills Automatic Merchandising Corporation of New York.
