Application filed June 17, 1914. Serial No. 845,672.

To all tUlIO/Ilit may co/ucrn Be it known that I,-K;\nn llnnomn OLsoN, acitizen of the United States, residing at llrockton, in the county of' llymouth and State of Alassachusetts, have invented certaln new and useful Improvements 1n Yortable Fire-I'Iscapes, of which the following 1s a specification, refcrcnce'being had to the accompanying drawings.

This invention relates to new and useful improvements in fire escapes, and particularly to that class of fire escapes which are portable.

An objcctof this invention is the provision of a fire escape which is'rclatively small in size so that the same may be easily carried about from place to place in a trunk or the like, the device being adapted for easy and rapid connection to the frame of a window so that a person using the same may quickly lower himself to the ground.

A further object of this invention is the provision of a fire escape which comprises a yoke having a pair of hooks connected thereto for supporting the device upon a window ledge or the like, the yoke carrying a block around which a rope is passed, one end of the rope carrying'a body support, the free end of the rope being grasped by the person carried by the" body support .so that he may lower himself to the ground,

the frictional engagement of the rope with the block materially relieving the weight of the body upon the arms of the person.

lVith these and other objects in view, my invention consists in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

igure 1 is a perspective view of my device, showing the same in use; Fig. 2 is a perspective view of the body support; and

3 is a detail sectional view.

ferring more particularly to the drawing, the numeral 1 designates a U-shaped supportin plate, the parallel ends of which are prov ded with angular openings 2 through which extend the angular ends 3 of a cyllndrical block 4. Connected to each projecting end 3 of the block is one end of a rod 5, the rods rearwardly of the plate being twisted as at 6, and being thence bent to form hooks 7 by means of which the device may be supported upon the ledge of a window or the like. A cord 8 is passed around the block 4, o ne end of the cord being passed throhgh an opening 9 in the plate intermediate of its ends, the end of the cord which extends through the opening being connected at its extremity to a body support.

The body support comprises a chest encircling strap 11 which is provided at one end with a series of openings 12, the opposite end of the strap carrying a buckle 13, the tongue of the buckle being adapted to engage through any one of the openings 12 so that the chest strap may be secured around personsof various sizes. Secured to the strap 11 adjacent its opposite ends are the ends of a supporting strap 14 which is connected intermediate of its ends to the free end of the cord 8 after the same is passed through the opening 9 in the. plate 1, the intermediate portion of the strap 14 bein disposed over the head of the person w o is carried by the chest stra 11.

In the practical use 0 my improved fire escape, the hooks 7 are enga ed over the Bill of a window or an article of fprniture with? in the room from which it is desired to lower around the'body and secured thereto, .where-' upon the person gras s the end of the rope closely adjacent to t e cylindrical block 4 and lowers himsclf by allowing the free end of the cord to pass upwardly so that the body support is lowered to the ground. It will be seen that the frictional engagement of the cord 8 around the block 4 acts as a brake upon the body support, so that less pressure is necessary upon the free end of the cord than the weight of the body carried in the support to hold the same from dropping quickly to the ground.

It will be seen that I have provided an extremely simple fire escape whichgnay be cheaply manufactured, and which maybe quickly applied to use, the escape being very light and compact in form so that the same y b readilv carried about from place to place in a trunk or other similar traveling and the block so that less power is necessitated to hold the carrier from speedy descent.

hus fully described my invention, 1P6 to claim and secure by Letters the character described conr haped supporting plate, the opof said plate having angular between the opposite ends of said 'l having angular extensions distlrough the angular openings in said oel x i, e\.en ions, a cord passed around one a body carrier connected to one. en

Q device (1 the character described C0111- 3 pl. to having its opposite ends dis p angularly in parallel relation with eaeh then said plate having angular openonnected at one end to saidangular openings formed in its opposi eends, a block having angular extensions at its ends disposed through the angular openings in said plate, rods conne ted at one end to the angular extensions, said rods being twist ed rearu'ardl of the plate and being curred to provide hooks a cord passed around said block, and a body carrier connected to one end of said cord.

4. A device of the class described comprising a U-shaped plate luring angular open ings formed in its opposite end ndrical block having angular ends nosed through the openings in the ends oi plate; supporting hookseoi'me i'cd at one end to'the angular ends of said blo k; said plate having a central opvnine' therein, a cord passed around said lilUCK. one end of said cord being disposed through the central opening of said plate, and a body carrier connected to the free end of said cord after the same has been passed through the central l
