Design drawing showing how the fabricated pulley fits together with the pedestals, end covers, shaft and soleplates to construct the mining headgear.

This week's #NewAccession is a diagram of a fabricated #headgear pulley, 14 feet in diameter and designed by Markham & Co, Chesterfield. This was used at #Williamthorpe Colliery to hold the winding wheel in place above an underground mine shaft.
