Default *RE: Sidewheels/Prof. Jack White*

Hi, Bob & Steamboatinc colleagues:
Thanks for the mention of the above publication featuring Prof. Jack White etc. Jack's research/writings stellar from start to finish with him providing insights not previously known. Some time back Jack provided 'grist' on the topic of lubrication products for steamboat engines that received great attention and comments. Jack has been featured in the S&D REFLECTOR numerous times in addition to his own publications. At times I wonder if Jack 'lurks' on .org and wonder what he thinks of our ruminations?

Interesting comments on location of sidewheels on boats. Seems a long time back Alan Bates also enlightened us on this matter RE: river steamboats with him mentioning the wheels catching the big wave rolling out and back. I'm no expert in liquid dynamics but appreciate comments on those more familiar. Sidewheelers with walking beam engines were, as stated, mounted more in the center. The huge D&C LINE steamers [Really ships] on the Great Lakes like this with incline reciprocating ones. The walking beams--and other incline engines--to the center for control of weight. Also the walking beams conserved more deck space for cargo etc. Yet, they did run up through the decks taking center space towering above with the diamond shaped beam 'walking' up and down, down and up. Usually only one main huge cylinder with some boats having two: high and low pressure and condensors. They were delicate jobbies to operate in starting up called 'dropping the hook.' One account of a big walking beam engine on a boat shattered due to a tablespoon of water in the cylinder while laid up in the winter. Those attending an S&D meeting in Marietta some years ago recall seeing the footage of the ALEXANDER HAMILTON roaring up the Hudson with her wheels chewing the water. Some in the audience gasped asking if the film footage was, perhaps, running too fast. It wasn't with the narrator stating the HAMILTON could hit 22 mph. 'Some' old sidewheel boats back east did have their engines mounted behind the wheels. Well, what do I know?
