Historical NotesA Tate Flexible stay bolt made by the Flannery Bolt Company. A stay bolt is used to fasten and stabilize plates under pressure, most commonly in locomotive boilers. The Tate Flexible stay bolt is a locomotive stay bolt type produced by the Flannery Bolt Company in Bridgeville, Pennsylvania after the acquisition of its patent by the Flannery brothers after 1904. Its manufacture eschewed the use of readily-available steel types considered inadequate for its construction. Flannery instead turned to vanadium steel for its manufacture. The Tate Flexible stay bolt was patented by John B.Tate on March 1, 1904. The patent number is 753,329. The Flannery Bolt Company was established by the Flannery Brothers, James and Joseph, in 1904 in Bridgeville, Pennsylvania. The brothers were also responsible for founding the American Vanadium Corporation in 1907 and Standard Chemical Company (SCC) in 1911. This bolt was obtained from the Strasburg Railroad locomotive shop. It was part of the last steam locomotive shop of the Reading Railroad. After ending its steam locomotive operations, the Reading Railroad donated the shop's inventory to the Strasburg Railroad. Donor Joel O. Lubenau purchased the bolt from the Strasburg Railroad in 2009.
