19 The Roberts-Gibson Discharger was put to the test at the German-American Sugar Company’s Bay City, Michigan plant, where it performed well. The two men refined the designs and obtained patents for their innovations. Recognizing the potential market for their inventions, they assembled a group of six investors and started a company on July 15, 1908. The Sugar Centrifugal Discharger Company of Salt Lake City was headed by Joseph R. Murdock, with Roberts as Sales Manager (until 1916, when he became Business Manager), Gibson serving as Vice President, and Joseph W. Musser as Secretary-Treasurer. Other Directors included D.H. Gustaveson, M.F. Cowley, and Joseph H. Gardner. The new company turned to the Boston-based American Tool and Machine Company for manufacturing. That enterprise had been marketing its own centrifugals, and in addition to building the Roberts-Gibson products, began to incorporate many of Roberts’ ideas into their own installations. left: The first capital stock certificate issued on August 14, 1908 to Eugene Roberts for the Sugar Centrifugal Discharger Company.
