The Victoria Tower - Elevation of the Hoisting-Scaffold, 1850. 'Progress of the New Houses of Parliament...In Fig. 2 we give an elevation of the scaffold ; N N being the walls of the tower, M M the guide-posts, and 1 1 one of the cross-trusses. B is the hoisting traveller, A being the wheel over which the chain (D) from the windlass (E) passes. The traveller has a collar which encircles a hollow shaft (F), up which the chain (D) passes, thence over C, and on to A. The other travellers have similar collars, but have no chains communicating with the windlass (E); they have windlasses running on rails on them, as at K, so that stones and other materiel can be lifted, carried, and placed at any spot with the greatest precision and facility. J represents one of these carrying travellers; and at o o, on both the travellers, are the wheels of the tripels running on the circular rail'. From "Illustrated London News", 1850.
