Fl RE-ESCAPE.

{JPEGILCATIO forming part of Letters Patent No. 311,889, dated February ILO, 1885.

Applica-tion filed December 19, 1884. (No model.)

.T0 all whom, it may concern:

Be it known that we, IsAAo FAEEE and JosErHAErJAH PowERs, of Boston, in the county of Sui't'olk, of the Commonwealth of Massachusetts, have invented a new and useembracing our invention, the nature of which is defined in the claim hereinafter presented. Fig. 2 is a perspective view ot'it as applied to a person, aud ready for use by him in escaping from a building on iire. Fig. 3 is aback view of a person with the tire-escape as applied to him.

In such drawings, A denotes a rope provided at one end with a loop, a, to receive one of the legs of a person. Above this loop the rope goes upward through a ring, b, and next downward and again upward through such ring. so as to form another or shoulder loop, c, which, when the tire-escape is in use, goes under one arm, and thence upward across the back and over the shoulder of the other arm of a person, and thence extends through the eye of a hook, B. v'lhence the rope goes downward through another ring, d, that slides on the leg-loop a. On the part of the rope which is next below the said ring d is a clamp, C7 having two sets of jaws, e e, to grasp the rope, they being caused to do this by springs ff between the tails of the levers g of the jaws.

With the fire-escape applied to the body of a`man in manner as shown in Fig. 2, in which one of his legs is represented as going down through the leg-loop, and the latter drawn closely up into the crotch ofthe legs, the other loop being also applied about the shoulder of one arm and extended under the other arm and across the breast and back of the person, he is to hitch or properly secure the hook into a window-casing or to some article of furniture in the apartment. Having done this he is to pass out ofthe window. The rope in such case will be drawn upon, so as to pull the clamp up to the ring of the legloop, in which case the person will be suspended from the window, and by seizing the hand-clamp and operating it so as to causeits jaws to operrinore or less, he can descend, the rope in the meantime slipping through the eye of the hook and the jaws of the clamp.

Instead of the hook B we sometimes use a common pulley provided with suitable means ot fastening it to a bed-post or other convenient device in an apartment from the window of which it may be 'desirable for a person to escape.

The 'tire-escape, substantially as described, consisting of a rope provided with the legloop a, the ring b, shoulderloop c, hook B, leg-loop ring d, and clamp C, all arranged and for use substantially as set `forth.
