FIRE-ESCAPE.

SPECIFICATION forming part o'f Letters Patent No. 654,359, dated J' uly24, 1900. Application filed May-17, 1899. Serial No. 717,130. (No model.)

To @ZZ whom t may concern:

Be it known that I, EUGENE T. RYAN, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in Fire-Escapes, fully described and represented in the followingspecification and the accompanying drawings,

forming a part of the same.

This invention relates to improvements in nre-escapes, it being the object of the present invention tofprovide a simple and efficient fire-escape which is controllable from a distant point and operated in such way as to insure the delivery quickly of the fire-escape in proper position for use in case of re.

In the accompanying drawings, Figure lis a vertical section of a building the roof of which is equipped with fire-escape apparatus embodying the present invention in its preferred form, such apparatus including a fiexible ladder,'means for retaining it in its folded or coiled condition, and connect-ions for releasing it. Fig. 2 is a detail in section, on an enlarged scale, of the fire-escape apparatus. Fig. 3 is a plan view ofl the same. Fig. l is a front elevation of a portion of the ladder; and Fig. 5 is a front view of a building equipped with a number of the fire-escapes of the preceding gures, with connections for simultaneously releasing them.

Referring to said drawings, A represents the fire-escape proper; B, the base-board on which it is mounted; C, a spring for propelling the fire-escape or ladder A forward to the edge of a roof or wall, over which it falls into position for use, while D represents a movable hood which in its closed position compresses the propelling-spring C and which is held normally in such closed position by a lock E.

The fire-escape or ladder A is secured at as shown, and rests upon the propelling-spring' C, which is preferably formed, as shown, with L side arms for engaging the coiled or foldedladder nearfitsside edges, said side arms being also curved downwardly, as shown, so as to retain the Yfolded or coiled up ladder in proper position longitudinally of the spring C. "By reason of this construction and arrangement of the side arms of the spring the latter forms in effect a cradle on which the coiled or folded ladder will be evenly balanced and which when released will propel the ladder forward in a straight line.. The spring C may act to propel the ladder either by slowly inclining itself, so that the ladder willsimply roll down the same, or by abruptly assuming such inclined position, so as to throw or shoot it forward, the ladder in either event being automatically delivered to position for use. The hoodl) is hinged `at the rear end of the base-board B and is provided with 'a top and sides, so as to completely inclose the ladder and spring, and thusprotect them from dust and dirt and from being tampered with byfunauthorized' pe1' sons,and also in case the apparatus be located, asitwill preferably be, on the roof R of the building, as shown, protect these parts from the elements. The hood D is held in its closed position, as before stated, and the spring O therefore held under tension by a lock E, which may be of any desired construction capable of control by any suitable mechanism, so as to be released from a distant point, but is preferably a block of fusible metalincluded in an electric circuit F G, running down through the side or outside point-as, for example, the office or main hall of a hotel or other building or a suitable' signal-box in the streetwith a circuit-closer H. Preferably each buildingwill be providedwith a number of these apparatus, and in such,case a single circuit will be provided for simultaneously releasing all, as shown in'Fig. 5. y

As before stated, the fire-escape apparatus of the present invention will preferably be located on the roof of the building in rear of the projecting cornice I, as shown, so as to be out of View when not in use and so that the fire-escape or ladder` A when extended will be supported by the cornice and thus held away from the face of the wall a suitable distance to enable the user to secure a good hold on the ladder with his hands and feet and to descend rapidly and without injury from the IOO wall, the ladder at the same timebeingheldv sufficiently close to the wall to be within convenient reach of the occupants of the building standing upon the window-sills. Each fire-escape apparatus, moreover, will preferably be arranged in line with a tier of Windows, so that it will fall directly in front of such windows.

The ladder A is preferably of the construction shown in Fig. 4-that is to say, with side rods or bars of Wire rope and steps a of suitable rigid metal, preferably tubular, which are connected to the side bars or rods by means of T-shaped tubes b, provided with threaded openings for receiving the correspondingly-threaded ends of the steps ce, the rigid steps being employed so as to keep the side bars separated under the weight of the person descending the ladder.

The manner of using the apparatus is as follows: As the parts are shown by full lines in the several figures they are in their normal positions, each ladder being coiled or folded up within its hood D, which is held closed by lock E, the spring C being in turn held under tension by the hood D. In case of iire all that is necessary to be done to bring the fireescape, or {ire-escapes if there be more than one, into position is to close the circuit through F Gr by closing the circuit-closer H at the office or other point inside or outside of the building. With the circuit thus closed the lock or locks E will speedily melt, thus releasing the hood D, which in turn releases the spring C, which throws the hood back- Ward and assumes an inclined position, thus causing the coiled or folded ladder A to move or be thrown over the edge of the cornice I and then to extend itself and descend, all as shown by dotted lines in Fig. 1. The ladder A Will of course be of such length that its free end will approach the sidewalk closely, so that it may be seized, if necessary, by firemen or others for the purpose of steadying it while the occupants of the building are descending or firemen or others are ascending to the assistance of the occupants or for any other purpose.
