About the mine cage safety detaching hook 

John King’s detaching hook is a safety device which detaches the cage from the rope in the event of an overwind in the shaft: Where the cage would rise above its proper unloading position. By the second half of the 19th century with increasing demand for coal to power industry, technological advances resulted in even faster cage winding. Subsequently, the cage could be wound up and over the headstock pulley wheel with disastrous consequences for the miners inside. John King’s safety detaching hook was successfully trialled at Pinxton No.1 colliery in 1873.
