The cassions, the fancy french word for the thing I called the bath tubs, are raised and lowered by means of two £2 million pound Teflon coated rams. Using hydrolics, they can be operated independantly, but more economically they can be operated together each using the other as a cointerbalance. Originally before the use of hyrdolics, the lift worked by using large weights, gears and again counterbalance. I have attached a picture of one of the original gears. The year was the late 1800s. Can you guess who designed the gears? Answers tomorrow. Clue: the answer is in the picture.
Mmmmm .. can't see any names of who might have designed the gears .. bit of a fuzzy photograph. Pretty impressive though!

"Cassions" sounds delightfully French, but the things are actually called "caissons". Probably French as well.
ReplyDeleteThe weights, gears, and counterbalance were all added later when the lift was first electrified. Before that it worked on pure hydraulics, until the salt in the water corroded the pistons away.
