Hi Ian,
***I found your email in my 'Spam' folder, and it didn't appear on the Mining History List!
***Same happened to those from Mike Gill and Dave Hardwick - thank you all for your responses.
***Is something strange happening with Jiscmail??
Answering the query in your email Ian, it seems that Stephen and James R Eddy could without too much difficulty have put in some kind of machinery at Snailbeach mine for raising and lowering miners, after they contracted to manage all the Snailbeach works in 1857.
When the lessor, the Marquis of Bath, began to use top mining consultants to advise him and help negotiate his leases, Thomas Sopwith made it known that the Eddys' contract, with a rather small salary but a percentage commission on profits on top, encouraged development to be neglected. A machine for transporting the miners was one thing not done. Improvement to the water supply for ore dressing was another. They needed capital investment which would have reduced profits, so reducing the commission payments.
When Henry Dennis took the management contract in 1871, he accepted a larger fixed salary, without any commission on profits. A twin cage winder down to 252 yards and a large reservoir were both finished by 1872.
This is why I was asking if there might be other general reasons for not putting in a cage winder (than money).
Cheers,
Andy Cuckson

The cage tub and guided rail system was invented by T.Y.Hall on Tyneside in the 1830s - primarily for hauling coal but also for the men and boys. The first effective system was at Glebe Pit, Ryton and soon went into widespread use. Better ropes and more powerful engines gave increased performance. See R.L. Galloway Annals of coal mining vol 1, 481- and vol 2, 328- for more details.
But why should companies avoid something that would raise productivity?

When and where in Britain was the first system installed for winding miners up and down from the surface in cages attached to a cable?
Apart from capital cost and maintenance, were there particular reasons why mining companies might have avoided installing them?
Many thanks,
