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.
