Fl RE-ESCAPE.

SPECIFICATION forming part of Letters Patent N 0. 516,528, dated March 13, 1894. Application filed September 4,1893. Serial No. 484,721. (No model.)

To-aZZ whom it may concern.-

3e it known that I, EUGENE GOLDBERG, a CltlZeD of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Fire-Escapes, which improvement is fully set forth in the following specification and accompanying drawings.

My lnvention consists of a fire escape composed of an extension ladder, a frame or casing adapted to receive the same, means for holding said casingwith the folded ladders on the roof or upper portion of a building, and means for releasing said casing, whereby it descends and permits the unfolding of theladder, whereby the latter is placed in position to be reached by the occupants of the building, all as will be hereinafter fully set forth.

It further consists of the combination of parts hereinafter set forth and claimed.

- Figure 1 represents apartial side elevation and partial'v'ertical section of a fire escape embodying my invention. Fig. 2 represents a front elevation of the fire escape.-

Similar letters of reference indicate corre sponding parts in the two figures.

Referring to the drawings: A designates a drum mounted on the roof B, of a building 0, and operated by a crank D.

E designates chains or ropes wound around the drum A, and connected with the bottom sectlon of an extension-ladder G, so that send sect1on may be raised by the winding of said chain or rope.

H designates a frame or casing provided with projections or rollers J, adapted to travel on rails or guides K, secured to the roof B, and adjacent to the eaves of the same. The

ends of the rails K which project beyond the caves of the roof are provided with hooks L, into which the rollers J are guided by the rails K. The hooks L prevent the rollers J from leaving the rails K, and permit the casing H to hang from the former, when theladder G is in its operative position. The frame H is provided with a dog M adapted to engage with a l'ugNsecured to the roof B, so as to retain the frame on the roof B in the position shown in dotted lines in Fig. 1, when the ladder G is not in use.

P designates a chain, rope, wire, &c.,- secured to the dog M, so that the latter may be disthrough the eye Q is guided by rollers S on the casing H.

, When it is desired tolower the ladder G,

the chain P is'pulled soas to cause the dog M to leave the lug N, and the casing H then slides down the inclined roof and the rollers J enter the hooks L, and act as pivotsfor the casing H, and permit the latter to turn and then hang in a vertical position, so that the several sections of the ladder G may drop into the positions shown.

When it is desired to restore the several parts of the device to their normal positions, the crank D is rotated, and causes the chains E to wind around the drum A, and raise the bottom section F of theladder G, said section sliding freely on the one'above it, until its bottom lips T abut against those on the section above, Both sections now rise together until the lips T reach the under side of the top section,-when this latter will also be raised by the action of the other sections, and the ladder G in folded position willbe drawn by the chains E into the casing H, and the latter in turn will bedrawn by the chains E which pass over the plane of the centers of the rollers J to the position shown in dotted lines on the roof B, it being noticed that the said chain has greater incline than the roof, or rather that the peripheryof the drum to which the said chain is connected is at a greater distance from the roof than arethe centers of the rollers J. When the casingH has reached its normal position, the dog M engages with the lug N, and said casing is then securely held in placeon the roof B.

Inlieu of the crank D, I may employ a roller which is secured to the shaft of the drum A as shownin dotted lines Fig. 2, the same being adapted to be rotated by an endless rope or chain within convenient reach of either window, especially the upper one.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isg 1. In a fire escape, a casing, and a ladder adapted to be folded therein, a drum on the building, and a chain or rope connected with said drum and easing, a tooth on the building, a dog on the casing and a chain or rope connected with said dog, the parts named being combined substantially as described.

2. In a fire escape, the hooks L on the building, and the ladder casing with projections adapted to engage with said hooks, the parts named being combined substantially as described.

3. In a fire escape, the rails K on the building, the hooks L on the ends of said rails at the eaves of the building, the casing I-I adapted to engage with said hooks and the extensible ladder connected with said casing, said parts being combined substantially as de permitting the descent and unfolding of the ladder, said parts being combined substantially as described.

5. A fire escape consisting of a casing having rollers thereon, and an extension ladder therein, a rotatable drum, a chain connected with said ladder and drum, and rails having hooks at their ends, said parts being combined substantially as described.

6. In a fire escape, a casing with asectional extension ladder therein, each of said sections having a projecting lip on its lower end, substantially as described.

7. A fire escape having arotatable drum, a casing with a sectional ladder therein and rollers thereon, a track for said rollers, a chain connecting said druin and ladder, a lug adapted to be secured to a stationary support, and a catch on said casing engaging said lug, said parts being combined substantially as described.

EUGENE GOLDBERG.
