Michigan Canning and Machinery Company
The Dunkley Company was a packer and canning equipment manager started by S. J. Dunkley in Michigan. Dunkley started off packing celery in Kalamazoo, Michigan, then canning peaches in South Haven and Hartford. He later invented a cherry pitter among other machines and eventually moved completely into mechanical devices for canning. His company Dunkley moved his company to Oakland, California in 1915. The company was continuing to lease and maintain canning equipment in 1949. The company was apparently owned by Libby in 1981
In 1916, the Dunkley Company sued many California fruit packers for infringing on the company's patents. The company move may have been related to the lawsuit. During the hearings discussing changes to the 1920 Packer's Decree, the wholesalers at Tillman and Bendel claimed that Dunkley was actually controlled by the meat packer Swift and Company, and their control existed only to attack independent California canners.

"Although no dollar figures were announced, it is believed that the deal involved millions of dollars, and would leave Libby with its fruit juices and specialty foods units that it operates under its Crosse & Blackwell and Maggi, Florida Citrus Groves Corporation and Dunkley Company subsidiaries. The company also said it was planning new acquisitions and product lines, but refused to elaborate."
