FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent N0. 274,338, dated March 20, 1883.

Applicationflled October 1,1862. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM FLETCHER JOLLEY, of Middlesex, in the county of Yates and State of New York, have invented a new and Improved Fire-Escape, of which the following is a full, clear, and exact description.

The object of my invention is to provide a fire-escape that is light, portable, and so arranged as to be folded into a small compass, to be carried on the ladder-trucks with the ordinary fire apparatus, to be used where it is desired, and to be placed below a person in denger in a building, and into which the person may jump without being injured.

Reference is to be had to the accompanying drawings, forming part of this specification, in

. which similar letters of reference indicate corterial. The edges of the canvas are turned over to form a hem, through which the rope B is run, and it is also stitched together, forming pockets at to contain the coil-spring sup ports 0.

1 Bars D, made of strong wood, and of suitable length, are' provided at each end with loops d, that are connected to each other by rings F, that pass through the loops d.

The coil-sprin g support 0 is formed ola rod, f, doubled upon itself, and having at one end a loop, 9, to receive the ring F. The rope B is also secured in the loop g, and rests upon a movable washer, it, placed on the doubled rod f, and a washer, 'i, is firmly secured to the opposite end of the rod by passing the ends of the rod through the washer and bending them outward or in any mannerto retain the springs. Between the washers h t is placed an open coilspring, j. One of the spring-supports U is secured to each of the rings F, and one or more to staples e of the bars D, as may be requiredfor the supportof theblanketA. When more than one of the spring-supports C are used they are to be at equal distances apart upon the bar D, and are secured in the poohets a in the blanket A. The rope B is passed through the loops 9 and hem of the blanket A, and the ends firmly secured to each other. A body falling on the blanket will cause the coil-springsj to yield, allowing the blanket to settle gradually.

The supporting-frame of the escape consists of four bars, G, of nearly equal length, placed one on each side of a square block, H, that is a trifle larger in cross-section than the bars G, and to which they are pivoted by bolts k, the bars on the opposite sides of the block being pivoted by the same bolt. One of the bolts 1c is placed a little above the other to allow them to pass in the block H. With this construction thebars G are adapted to be placed in position for use, (shown in Fig. 1,) and also to be folded parallel with each other. The upper ends of the bars Gare reduced and rounded to receive the rings F, which rest on theshouldersformed byreducing theends of the bars. 7 The lower ends of the bars G are square, and on the outer side of each bar are placed extension-pieces I, that are of the same width as the bars G. The extension-pieces I are adjustably secured ,to the bars G by clips J, that are attached to the lower ends of the bars G, and to the upper ends of the extension-pieces I, adapting the bars and extension-pieces to move on each other toraise or lower the escape, or to adapt it to uneven ground. The bars G and extension-pieces I are secured to each other when properly adjusted by the setsorews K, or in any suitable manner, to prevent the extension-pie'ce I from sliding upon the main bar G.

On the outer side of one of the bars D are two loops, l, to which is attached the upper end of a rope ladder, L, thelower end of which reaches the ground, and by means of which a person may descend from the escape to the ground.

It will be seen that the supporting-frame and the blanket and its frame may be folded into asmall space, making the escape portable, and to occupy but little space onaladder-truck.

The escape is easily set up, and when aperson jumps upon the blanket from a building the coil-springs are compressed, causing the force of the rapid descent to be broken gradually, preventing injury to the person.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In blanket fire-escapes, the combination of the rigid bars I), having end loops, cl (1, and the rings F, connecting said loops, to form a stretching-frame for the blanket, adapted to be used as described.

2. A fire-escape blanket made with the radial pockets a, a rope pocket or receptacle about its periphery, and peripheral excisions shown in Fig. 3 of the drawings,'and for the purpose specified. I

5. The combination, with rings F, connecting with loops onthe ends of bars D, of the cross pivoted legs or bars Gr, held in said rings at their upper ends, whereby a convenient detachable connection is formed between the stretcher-frame and the leg-bars, as shown and described.

6. In a fire-escape, the bars D and rings F, in combination with the blanketA and springsupports 0, substantially as shown and described.

7. The combination,with a fire-escape made substantially as shown and described, of the ladder L, as specified.

8. In a fire-escape made substantially as shown and described, the supporting-bars- G, block H, and extension-piece I, in combination with the blanket A, spring devices 0, bars 1), and rings F, as set forth.
