Talk:Beam engine
From Wikipedia, the free encyclopedia
A few comments, if I may:
- a beam engine is not necessarily stationary;
- the piston rod does connect to a connecting rod (by definition!) but this rod is not the one which directly drives the crank (also see next point);
- beam engines did not necessarily have a crank or flywheel;
- the Newcomen engine was a beam engine.
- James Watt was indeed responsible for significant development of the steam engine - I have not seen this position questioned (I'm not saying it has not been).

- Also, the beam engine was first put into wide, heavy use in Cornwall, where the technology was pioneered by the likes of Richard Trevithick, and Harvey's of Hayle. Cornwall was so influencial of the beam engine that the house it was installed in, simply "Cornish engine house", became part of a logo (usually a sticker) applied to items with the distinction of being made in Cornwall. A complete list of the uses of a beam engine should include; winding on a mineshaft (raising ore and raising and lowering miners), pumping using a wooden pumping beam down a dedicated pumping shaft, pumping using flat rods, lowering and raising miners on a "man engine", raising and lowering skips on an inclined railway, turning ore crushing stamps, and pumping while operating an inclined railway (using an old winding engine to run a flat rod beam pump, a use which was adopted during the conversion of many metal mines to china clay mines). To clarify, James Watt was an early pioneer, Richard Trevithick was a later Pioneer, whom James Watt frowned upon for using the "dangerous" high pressure steam. --Badharlick 02:35, 19 May 2006 (UTC)

- Furthermore, a beam engine is not necessarily driven by steam – the present illustration shows a water-powered engine! Gosh this article does need some work... -- EdJogg 00:57, 28 February 2007 (UTC)
