FIRE-ESGAPE.

' srncrrrcATIoN forming pm @Letters Patent No. 629,228, dated Juny laisse.

Application led May'- 9, 1899. Serial No. 716,119. (No model.) i

ToV .all whom it may concern):

Be it known that I, Jost: DnLeADoY Aer IAR, of the cityof New Yrk,borou gh ofBrooklyn,lin the county of Kings and State of New York,phave 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 construct a strong and economic device adapted for permanent attachment within a building -or at the outside thereof which will provide means of escape from fires in buildings of any height or number of iioors and with the greatest possible rapidity and safety.

' Another object of the invention is to construct a fire-escape so simple in operation that the most excitable person can success-v fully make use of it.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed Yout in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a partial sectional perspective view of a building, illustrating the improved fire-escape applied to both the inside and the outside of the building. Fig. -2is a front elevation of the improved tire-escape, drawn on. an enlarged scale; and Fig. 3 is a side elevay l Y tending from the bottomto the top door, and

tion thereof.

When there-escape is to be applied to the upon the roof of said building, which bracket projects beyond the cornice. A spindle is mounted to slide in V'the' outer end of the bracket A, said spindle being attached below the bracket to the frame 11 of a peripherally n grooved pulley 12. The spindle 10 is provided with a head 10a,` and a spring 13 is coiled around the spindle, having bearing upon the bracket A and against the said head 10a. A hanger 14 is secured to the under surface of the lowest oor C of the building. This hanger is providedwith a .downwardly-extending arm 15 and a horizontal xed shaft 16,upon which shaft 16 a peripherally-grooved pulley 17 is mounted to turn, the pulley 117 being-in vertical alinement with the upper pulley 12.

4is best shown in Fig. 2.

tends beyond the arm 15, and a blade 21 is outside of the building, a bracket A is secured A gear 1S is secured to the back oi the pul ley 17, and this gear meshes with a pinion 19, secured on a shaft 20, which shaft is mounted to revolve in the hanger 14 and its arm 15, as The shaft 2O eX= attached to the 4projecting portion of said shaft. An endless chain orl cable 22 is passed around both pulleys 12 and 17, the cable orl chain being vheld under perfect tension at all times by the spring 13 on thesupport for the upper pulley 12. .The inner stretch of the chain or cable 22 is made to pass through atube 23,which tube is secured by screw-eyes 24 or their equivalents to the surface near which the escape'is erected, vand the object of the tube 23 is to prevent persons grasping the inner stretch of the rope, compelling them to take the outer stretch, so that by yno possibility can persons use the escape in such manner. that the weight of one would practically counterbalauce the weight of the other, thus preventing the descent of either to the ground.

When a person grasps the outer stretch of the cable 22, the cable will turn quickly on vthe pulleys 12 and 17, and the rapidity of the descent will be controlled by the blade 21, which will be revolved as the person descends, said blade thereby serving as a retarding device.

When the escape is to be erected within a building, a fireproof shaft 25 is erected, ex-

the upper portion ofthe escape is secured to the ceiling of the uppermost apartment within the said shaft. This flreproof shaft 25 at each floor except the lbottom door is provided with a vwindow 26 at one sideand a door 27 oppo site to the window, the doors 27opening outward, and these doors are provided with spring-hinges that' will close immediately upon a person entering the shaft, thus preventinglames from gainingaccess to the interior of the shaft. At the bottom licor a door 28 is located in the shaft, openingoutward to'facilitate the .ready exit of any person descending by the fire-escape.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The herein-described fire-escape consisting of an upper support, a spindle fitted to slide IOO e I weee in said support and provided with a head above the same, a spring coiled around said spindle and bearing against the support and head, a pulley-frame carrying a pulley and secured to the spindle below the support, a hanger below the support and having a fixed shaft secured therein and n downwardly-extending arm, a pulley mounted on said shaft, being connected with the first-named pulley and having a, gear-Wheel secured thereto, and 16 a rotary shaft tted in the hanger and its' arm and carrying a pinion at one end meshing with said gear-Wheel and a blade at its other end, as set forth. d
