itself to every one. It is small enough to be easily carried, and is so
arranged that the person using it to let himself down from a burning
building can control the rate of speed at which he descends, and avoid all
danger of a sudden fall.

It is firmly hooked on to a clamp that is provided with it, and it
consists of a seat attached to two pulleys, through which the ropes pass.

The person seeking to escape from the fire places himself on the seat,
and, grasping the pulley firmly, lets himself out of the window. By means
of an attachment he is able, as we have said, to regulate the speed of his
descent.

This invention ought to be of great service to all those who live in high
buildings.
