By 1859 the Fulton Foundry & Iron Works were manufacturing mining machinery, steam engines and sawmills. Mining machinery is outside the scope of this website but over the years it was the most important product lineup for this maker. In 1859 the Fulton Foundry & Iron Works was operated by Hinckley & Co., a partnership consisting of D. B. Hinckley, William E. Worth and William A. Field. Their premises were located on First Street between Market and Mission Streets, San Francisco, which by the following year had become "45, 47, 49 First St."

From 1859 Langley's San Francisco Directory

Sometime during 1866-67 the business moved their works to larger premises at Fremont, Beale and Tehama Streets, with their office at the northeast corner of Fremont and Tehama Streets. By 1871 the partners in Hinckley & Co. were D. B. Hinckley, L. C. Marshutz, J. Brands, and D. E. Hayes. In 1872 they began manufacturing locomotives. In 1873 J. Brands and D. E. Hayes left the partnership.

We have not found much information on this business for the years 1873 to 1890; by that latter year the partnership had become Hinckley, Spiers & Hayes. In 1894 they relocated their main works to Harbor View in San Francisco, with branch works and office located at 213 First St. By that year the name had changed to the Fulton Engineering & Shipbuilding Works and the separate works and partnership arrangement had disappeared. They seem to have absorbed a separate business, F. A. Huntington (Globe Iron Works). By this time the manufacture of sawmills had ceased.
