To all whom it may concern Be it known that l, ALFRED S.PHIL13RooK, of Glaremont, in the county of Sullivan and State of New Hampshire, have invented an Improvel Fire-Escape, which invention is fully set forth in the following specification, reference being had to the accompanying drawings.

D D D are knobs of wood, or other suitable material, placed at convenient distances along the rope O, and held in place by knots F F F. Two stirrup sockets, one of which is shown in Fig. 2, tit onto the knobs D D D. These sockets have a stirrup attached to them by a line of suit.- able length, and also have an opening on one side, which admits of their being taken from one knob and placed upon another.

In using these a person descending would place a foot in each stirrup, resting his weight on one, while, with his hands, he detached the other socket and placed it upon a lower knob, and so on.

I claim as my invention 1. The combination of the hook A, the lever B, the rope O, the knobs D l) l), and the socket and stirrup, all constructed and operating substantially as described.

2. The combination of the stirrup and socket, constructed and operating substantially as described.
