French Patent # 935,346 - Super-Leader

French Patent 935,346 - Super Leader main image

This patent describes the design of the pulley wheels on later versions of the Super-Leader Route. These pulley wheels are split into two disc-like halves. These halves are joined together with small pins held in place by rather cunning spring clips. It is all very sophisticated - but the reasoning behind it eludes me.
