This collection documents the history of Hulett unloaders, machines designed by George Hulett to empty the cargo holds of Great Lakes freighters. These machines greatly increased the efficiency of the unloading process beginning in the early 20th century. A major portion of the collection is made up of architectural plans and drawings, but also contains correspondence, reports, newsclippings, and photographs, 1908-1990.
