OF CANTON, OHIO.

FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 406,257, dated July 2, 1889. Application filed November 26, 1888. Serial No. 291,919. (No model.)

To all whom it may concern.-

Be it known that I, OORA A. BUTLER, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new'and useful Improvements in Fire-Escapes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon,in which Figure 1 is an isometrical view. Fig. 2 is a view showing manner of attaching'the braces and bars to the suspending-chains. Fig. 3 is a front elevation showing the escape in proper position for use. Fig. 4 is a detached view of one of the braces. Fig. 5 is a view showing a modified form of attaching the braces and bars to the suspending-chains. Fig. 6 is a detached view of one of the bars. Fig. 7 is a sectional view showing escape attached and suspended. Fig. 8 is aview showing the escape folded.

The present invention has relation to fireescapes; and its nature consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claim.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, A represents the suspending-chains, which are formed of strong metal and as light as possible, reference being had to the amount of strength desired, and at thesame time providing a fire-escape that will be safe. To the suspending-chains A are securely attached the braces B and the bars 0. The braces B consist of four bars, preferably formed integral, and may be formed square or rectangular, or in the form of a trapezoid. The object and purpose of providing the braces is to throw or hold the outer bars of the braces away from the wall of a building. These braces should be so adjusted on the suspending-chains that they will come between the windows, as illustrated in the drawings, and are so adjusted for the purpose of having the inner bars of the braces abut against the wall. The bars O are so adjusted that-they will comeopposite the windows below the window from which the escape proper is attached or thrown out of. The braces B and bars 0 are so adjusted on the suspending-chains A that they will form a ladder when suspended.

Inuse, the chains A are securely attached to the hooks a, said hooks are securely attached to the wall at any desired point below the window, when the chains A are thrown from the window together with the braces B and bars 0, thereby forming a safe and convenient ladder, and at the same time setting the ladder proper away from the wall of a building.

It will be understood that the braces and bars should be formed of metal and as light as possible, reference being had to the desired amount of strength. In Fig. 5- a modified form of attaching the braces and bars to the suspending-chains is shown, which consists of an extension or arm passed through one of the'links of the suspending-chains and securely hooked or bent around the link.

It will be seen that by my peculiar and novel arrangement I am enabled to provide a fire-escape that will be safe, strong, and at the same time quickly and easily adjusted for use. In Fig. 2 a collar (1 is shown, which is securely attached to the suspending-chainsA, one of these collars being located at each corner of the braces B, or each end of the bars 0.

The escapes should be so located and arranged that the ones from the upper windows will not interfere with the ones from the lower windows when they are suspended for use. In the drawings two braces are shown between the Windows; but a greater number may be used, if desired.

Having now fully described my invention, what I claim as new, and desire to secure by LettersPatent, is-

In a fire-escape, the combination of the suspending-chains A, the braces B, attached to the suspending chains and adapted to abut against the wall of a building between the Windows, the bars 0, attached to the outer In testimony that I claim the above I have suspending-chains and adjusted to come opherennto subscribed my namein the presence posite the Windows below the one from which of two Witnesses.
