180. ROSE, JOHN THOMAS, Regent Street, Leith — Designer.
Design for a timber viaduct of great span, suitable for railway or other purposes. Its object is to unite great strength with simplicity; the beams forming it, are interwoven like basket-work, and the greater the stress thrown upon it, the more rigid it becomes. The same principle may be adapted to large roofs without the use of cross-ties, since the outward thrust upon the walls would be but small.
Supplementary model illustrating the principle.
