EARLY ENGINES had their mechanicals exposed for all to admire. An excellent example of this is a beautiful steam engine offered at the Bonham & Butterfields 2010 Quail Lodge automobile auction. The engine was part of the Michael L. Amalfitano collection that also included his race team’s Austin Mini Moke that recently appeared here at SimanaitisSays.
Here are tidbits on this engine described in the auction catalog, together with those gleaned from the Internet and books in my collection.
Steam Antecedents. The aeolipile devised by Hero of Alexandra in the first century A.D. was the earliest steam engine, of sorts.
Though Hero’s engine may appear to be only a demonstration of steam propulsion, there have been attempts at the concept’s practical use: According to Wikipedia, “In 1543, Biasco de Garay, a scientist and a captain in the Spanish navy, allegedly demonstrated before the Holy Roman Emperor Charles V and a committee of high officials an invention he claimed could propel large ships in the absence of wind… a copper boiler and moving wheels on either side of the ship.” De Garay’s idea was a combination of Hero’s aeolipile and medieval galley propulsion; the Spanish authorities weren’t buying.
Neither was Ludvig Wittgenstein’s steam-driven propeller more than a footnote to the career of this twentieth-century Austrian-British philosopher.
Rather More Successful Applications. Around 1712, Thomas Newcomen used condensing steam and atmospheric pressure to actuate an engine pumping water out of English mines. The Newcomen engine had widespread use.
By 1776, James Watt, with business backing by Matthew Boulton, had enhanced the modest efficiency of the Newcomen concept. Their engine became, as Wikipedia notes, “one of the driving forces of the industrial revolution.”
In the Boulton and Watt steam engine, boiler (b) fed steam to cylinder (h), alternatively from above and below a piston. Piston rod (s) transmitted this reciprocating motion to balance beam (t) which drove flywheel (y). The engine produced 10 hp at 25 double-strokes per minute.
The Emille Bally Steam Plant. Emille Bally was a nineteenth-century Swiss clock maker based in Geneva.
As suggested in the Bonham & Butterfields auction catalog, Bally built a cabinet-mounted two-cylinder steam engine to drive a jeweller’s lathe.
The Emille Bally Steam Plant fetched $14,640 at the Bonham & Brookfields auction back in 2010. I’ll bet its owner has enjoyed its mechanicals out where they can be admired. ds
