Bessemer was a prolific inventor and held at least 129 patents, spanning from 1838 to 1883. These included military ordnance, movable dies for embossed postage stamps, a screw extruder to extract sugar from sugar cane, and others in the fields of iron, steel and glass. These are described in some detail in his autobiography.

After suffering from seasickness in 1868, he designed the [[SS Bessemer|SS ''Bessemer'']] (also called the "Bessemer Saloon"), a passenger steamship with a cabin on [[gimbal]]s designed to stay level, however rough the sea, to save her passengers from seasickness. The mechanism – hydraulics controlled by a steersman watching a spirit level – worked in model form and in a trial version built in his garden in Denmark Hill, London. However, it never received a proper seagoing test as, when the ship demolished part of the Calais pier on her maiden voyage, investor confidence was lost and the ship was scrapped.<ref>[http://www.history.rochester.edu/ehp-book/shb/hb20.htm The Bessemer Saloon Steam-Ship] {{webarchive|url=https://web.archive.org/web/20071227134724/http://www.history.rochester.edu/ehp-book/shb/hb20.htm |date=27 December 2007 }}, Chapter XX, ''Sir Henry Bessemer, F.R.S.

=== Continuous casting ===
Bessemer also obtained a patent in 1857 for the casting of metal between contrarotating rollers – a forerunner of today's [[continuous casting]] processes and remarkably, Bessemer's original idea has been implemented in the direct continuous casting of steel strip.
