Based on patents, Henry Hibbard was the main inventive force behind the company. Initially these were iron/steel patents with the Taylor Iron and Steel Company (Tisco), then the Hibbard-Rodman-Ely Safe Company, which then became the Manganese Steel Safe Company. Later patents dealt with the iron and steel business. The following list includes a few related patents by others.
