Everett S. Sherman (1831-1897)〔 was a covered bridge builder in Ohio. He lived and built bridges in Delaware County then moved to Preble County after a storm destroyed many of its bridges.〔 He revived a technology of Childs truss bridges, of which only a handful of examples--perhaps only seven according to a 2003 report--survive in the United States. The Childs truss was patented by Horace Childs in 1846. It never became popular, but, after its patent expired, was adopted by Sherman for bridges in Ohio late in the 1800s. Sherman adapted the Childs design to vary the size of beams according to loads carried by them, rather than using uniform beams.〔(【引用サイトリンク】title=HAER document for Harshman Bridge )〕 A number of his works are listed on the U.S. National Register of Historic Places.
