.NITED STATES PATENT OFFICE TOBIAS LYNESS vAND JOSEPH P. DUNNE, OF NEW YORK, N. Y.

IMPROVEMENT IYN FIRE-ESCAPEs.

Specification forming part of Letters Patent No. 188,525, dated March 20, 1877 application filed January 29, 1877.

To all whom t may concern Be it known that we, ToBIAs LYNEss and JOSEPH P. DUNNE, of the city, county, and

State of New York, have invented a new and Improved Fire-Escape, of which the following is a specication:

In the accompanying drawings, Figure l represents a front elevation of' our improved fire-escape, and Fig. 2 a sectional side view ot' the same, showing it as applied to a house.

Similar letters of reference indicate corre` sponding parts. A

The invention relates to. an improved tireescape of simple and ei'ective construction, that may be readily applied for use in case of fire so as to provide a steady and reliable exit from any window.

This invention consists of a cross-piece with spurred end cheeks, placed across the inside of a window-casing, and having a rope-ladder suspended from adjustable eyes. The rounds of the rope-ladder are provided at the ends with brackets, and that part of the ladder which passes over the lower window is arranged with one or more crosspieces in place of the brackets.

In the drawing, A represents the main crosspiece, from which the entire lire-escape is suspended.l Cross-piece A is made somewhat longer than the general width of windows, and provided at the ends -with spurred cheeks B, that secure, the cross-piece firmly at the inside of the windowcasing when the'same is placed in position across the window. A ropeladder, U, is suspended from eyes Cl of crosspiece A, the eyes C1 being readily adjustable to greater or less width by sliding their sockets or bands on the cross-piece and fastening them by clamp-screws O2.

The rope-ladder is constructed with wooden rounds D, at suitable distance from each other, of which each round, or every second or third round, is provided with fixed cushion brackets or f'eet D', attached to the ends, which hear against the wall of the house and support the rounds at lsuch distance therefrom that they furnish a steady and convenient hold f'orthe hands and feet. Where the ladder extends over lower windows the brackets or supports D are not required at the rounds, butin place of the same one or more crosspieces, E, are used, that bear on the outside of the windowcasings, and are hung by axes or staples E l to the ropes above the rounds.

In case of tire, the main crosspiece is placed across the window-casing, and the rope-ladder,

with the lower cross-pieces, lowered from the window, after which the fire-escape isV ready for use, being rolled up into narrowvspacel when not in use, and forming. thus a simple,

cheap, and effective safety device for hotels,

tenement, and other houses.

Having thus described, our invention, we claim as new, and desire to secure by Letters Patent 1. Ladder-ropes G C, connected with a top cross-bar, A, by slide-bands having eyes O1, as described.

2. The cross-piece E, having eyes or staples E', resting on round and receiving the ropes,

as set forth.

3. A rope-ladder provided with wall-bracket D', consisting'of two corresponding prongs, rigidly fastened at their junction to the ends of rounds, for the purpose specified.

' TOBIAS LYNESS.

JOSEPH P. DUNNE.
