History of Paddle Wheel Boat

[edit]

I took the following paragraph out, because its reference clearly lacks solid proof: The use of paddle wheels to power boats goes back to ancient times, with the Roman army under Claudius Codex reportedly being transported to Sicily in boats propelled by wheels moved by oxen, and wheels in paddles later being used to propel galleys.

John Macgregor, Esq., barrister at law, London, in 'Notes on the Progress of the Paddle and Screw', Scientific American Volume 14, Issue 11, Nov 20, 1858: Pancirollus, who wrote in 1587, says he saw an old bas-relief representing an Illyrian galley propelled by three wheels on each side turned by oxen. The same author, and several others, refer to Vitruvius for a notice of the paddle-wheel, but I find, in five editions of Vitruvius, the drawings represent merely a wheel turned by the water, and used as a log to measure the speed.

Again, Claudius Codex is said to have employed paddle-wheels in the invasion of Sicily in the third century before Christ, and some MSS. in the King of France's library (which I have not been able as yet to inspect), are referred to for this statement, but after diligent inquiry, I can find no confirmation of it in any accredited authority.

Feathering mechanism

[edit]
Morgan's feathering paddlewheel

I think there should be an explanation of how the feathering mechanism works, ideally with a picture (animated?). I don't know enough about how it works to add this myself. --Roly (talk) 06:58, 4 August 2015 (UTC)[reply]

Commons has some images under Media related to Paddlewheels at Wikimedia Commons that might make it clearer. There have been several designs, but all broadly similar. Each paddle blade is hinged and controlled by a rod from the centre. These rods are linked to an eccentric. As the wheel rotates and the eccentric doesn't, the rods are pushed and pulled, in phase around the wheel. Andy Dingley (talk) 08:24, 4 August 2015 (UTC)[reply]
Thanks, Andy. I've added a short description and your diagram to the article. --Roly (talk) 11:55, 4 August 2015 (UTC)[reply]

Speed?

[edit]

How fast were early paddle steamers compared to the sailships they replaced? Presumably a combination of sail and steam was faster still? Crawiki (talk) 16:41, 4 April 2021 (UTC)[reply]

The France section is written like an advertisement and needs some work
