I have sent you diagrams from Practical Coal Mining by WS Boulton 1910 vol
2. So no-one else needs to scan them for you!
Cheers
Roger

Subject: [mining-history] Detaching hook
Hi All
I am after a good diagram showing how a detaching hook works. I know them
as 'Humble' hooks but they are also referred to as King's patent safety
detaching hook for mine cages.
I am putting together an interpretation panel on mine winding and I need an
illustration.
