Hornblower, Jonathan Carter (sh)




born July 5, 1753, Chacewater, Cornwall, Eng.
died March 1815, Penryn, Cornwall

British inventor.

He and his father, Jonathan (1717-80), worked for James Watt. Seeking to improve on Watt's steam-engine design, he devised the first reciprocating compound steam engine (patented 1781); his engine had two cylinders (see piston and cylinder), a significant contribution to Efficiency. In 1799 it was judged an infringement on Watt's patent.
