In 1933 the Muncie factory officially became the “Hemingray Division”, a subsidiary of the Owens Illinois Glass Company (listed as factory #26, and later, in about 1948, their factory number was changed to 86), but insulators made after that year continued to carry the “HEMINGRAY” name. The Hemingray factory and business offices were located on Macedonia Avenue, in the southern part of Muncie. The business offices remained at Covington until 1919, at which time all operation was moved to Muncie. The Covington factory also re-opened for a short time in the 1900-1902 period.
