Model. Demonstration model of fire escapes shown against a model house front. These models were made by Abraham Wivell to illustrate a series of lectures on fire-fighting that he gave in 1836. The fly ladder of the centre escape was swung into position with ropes and a rescued person could be pased down the canvas chute beneath the ladder. The model on the left, of an extending ladder, was les popular. These ladders were superceded by the lattice-girder extending fire escape, patented by James Shand in 1880. The model on the right represents a Shand Mason escape made in 1908. The models of firemen are in uniform.
