FIRE-ESCAPE.

Specification of Letters Patent.

Patented June 18, 1907'.

.Application filed October 6, 1906. Serial NO- 337365- To all 'Lo/"1,0m, t may concern:

Be it known that I, RICHARD BARTH, a citizen of the United States, residing in Oklahoma city, in the county of Oklahoma and Territory of Oklahoma, have invented a new and useful Improvement in Fire-Escapes, of which the following is a specific-ation.

This invention relates to fire escapes and more particularly to flexible ladders adapted to besecured to the window-frame, the object being to provide very simple and efficient means l'or securing the ladder to the frame.

Another object of my invention is to provide a very strong and durable ladder formed of a single piece of rope.`

Another object of my invention is to provide a lire escape which is very light so that it can be rolled up into a small package so that it can be readily carried Jfrom place to place.

With these objects in view, the invention consists in the novel features of construction, hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification F igure 1 is a perspective view of my improved ladder showing it in position to be used. Fig. 2 is a detail sectional view of a portion of a wall and window frame showing my improved supporting means secured in place. Fig. 3 is a perspective view of the supporting means. Fig. 4 is a detail perspective view of the ladder, supporting loop. Fig. 5 is a detail perspective AView of a portion of the ladder showing the manner of securing it to the loop. Fig. 6 is a,detail perspective view of a portion of the ladder. Fig. 7 is a perspective view of the brace used in securing the bit in place.

In the drawing A indicates the wall and B Y the window frame of an ordinary building. A bit C is adapted to be secured through the frame under the sill into the wall by an ordinary brace D, in the usual manner. The bit C is provided with an opening C in which is secured a ring C2 to which is adapted to be secured a snap hook E carrying a chain F to the other end of which is secured a snap-hook G, which is adapted to be secured to the eye H', of the loop H, which has overlapping horizontal ends H2 over which is knotted a rope I, (the ends I, I2, forming the sides of the lad- The end I is brought over andlooped at I3,

over the rope I2 about every one foot, and then brought back and twisted at I4 then looped around itself at I5 and then looped at I6 around the twisted portion I5. The end I2 is then looped at I7 around the loop I3 so as to prevent the same from slipping, forming a flexible ladder out of a single piece of rope which is very strong anddurable.

From the foregoing description it will be readily seen that I have provided a very novel fire escape constructed of a rope ladder which is very simple and cheap in construction and one which is provided with supporting means which can be easily and quickly attached without any danger of it pulling out.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a bit provided with a rung, of a chain connected to said rung carrying a loop having overlapping ends and a rope knotted over said overlapping ends having its ends formed into a ladder for the purpose described.

2. In a ire escape, the combination with a bit adapted to be secured under the window frame, of a chain connected to said bit carlying a loop with overlapping ends, and a rope knotted over said ends, the ends of the rope being formed into a ladder, for the purpose described.

3. In a fire escape, the combination with a loop adapted to be supported out a window,

of a rope knotted over said loop, one end of the rope being looped over the other end and the other end being looped over said looped portion to form a rung for the ladder, for the purpose described.

4. In a lire escape the combination with a loop having overlapping ends, of a rope knotted over said ends, one end of said rope being looped around the other end at intervals to.

form rounds, then. twisted and looped around itself, then looped around the twisted portion, and the other end being looped around the looped portion of the other end for the purpose described.

RICHARD BARTH.
