I'm sure Gloria will dig out the history of the Pelton wheel. The one shown is a double row of cups which are driven by jets of water. The shape of the cups suggests there is some element of axial impeller action to increase the overall efficiency, I seem to remember that some designs had a separate axial to take advantage of the water flow.

Yes, that's the first part of the question, it's a Pelton Wheel. Well done Gloria, but what about the inspiration for it?

Was it Leonardo di Vinci?

Sorry Gloria but no. More practical than that.

Don’t know.

I had no idea until I looked it up but Mr Pelton turned a hose on a cow to stop her disturbing his gold panning operations. The water hit her cup shaped nostrils and threw her head back which inspired him to design the turbine.

Exactly right Wendy and the ironic thing is that if you look at the Wiki page Gloria put up as an answer and skim down to the sources you'll find a link to the original news report on the story. 'The cow that assisted science'.

That’ll teach me to read down the page.

I would have thought that a jet of water up your nose or any other orifice would make you throw your head back. Sounds a bit like he's trying to create another Newton (Isaac) myth.

Cynic!!!

What is it? (It's about 40" overall length.)

DDT or other chemical sprayer.

Vacuum cleaner?

I'm with Kev, an early vacuum cleaner.

Aye, looks like some sort of bellow on the cylinder. A wireless vacuum cleaner

Australian I think...

Kev was first I think. Yes, a hand operated vacuum cleaner. From what I understand, not very practical!

What's going on here?

I know but I had to Google it.

I'd never heard of the custom either. Let's see how it goes....

It doesn't look as though it's going anywhere Ian, will you knock it on the head or shall I?

I'll leave it up to you Stanley seeing as you posted it.

Right. Have a look at THIS article on northern and eastern France’s Le Père Fouettard (Father Whipper), a sort of anti-Santa. And no, I had never come across this weird custom either.
Next for shaving?

What can you tell me about this image?
