MAX ROSNER, OF NEW YORK, N. Y., ASSIGNOR, BY DIRECT AND'MESNE ASSIGNMENTS, TO EDWIN D. HENDERSON, JR., OF NEW YORK, N Y.

FIRE-ESCAPE.

To all whom it may concern Be it known that I, MAX RosNER, a citi- Zen of the United States, and aresident of New York, county and State of New ,York, have invented a certain new and useful Improvement in Fire-Escapes, of which the following is a full, clear, and eXact specifica-' tion. I 1 This invention relates to a class of devices adapted to be used for saving persons when in a burning structure. I I

My invention has for its object primarily to Provide a fire escape, or device designed to be employed upon a building,- or other structure to permit persons confined therein when endangered by fire to readily escape without injury, and wherein is employed a chute adapted to be composed of one or more integrally constructed sectionsso' as to provide a continuous passage therethrough and which sections are disposed on inclines in opposite relative directions from each story of the building, in order to avoid too precipitous a descent for persons-to slide down the chute especially when applied to high structures, p

Another object ofthe invention is to provide in the chute a number of freely rotatable members arranged adjacent; to each other transversely of the chute and which serve to force the persons entering the chute to move in a downwardly direction therethrough.- I I I A further object of the invention is to provide a fire escape which is susceptible of being constructed entirely of cement, or other material which is non-inflammable and a non-conductor of heat, or maybe made of cement and metal combined in a manner to prevent the flames of a burning structure from contacting with and heating the metal, and a still further object of the invention is to provide a form of chute upon the top of which may be constructed a stairway.

With these and other objects, in view, :the invention will be hereinafter more particularly described with reference to the accompanying' drawings, which form a part of this specification, and will then be pointed out inthe claims at the end of the ,descrlption. s v I In the drawings, ,Figure 1 is fragmentary view of a building with one form of fire escape embodyingmy invention applied thereto, parts of {which are broken away. Fig. 2-is a view, partly in section, taken ,on the lineI I-eIIof F ig l. Fig. :3

is a view, partlyfin section taken on the line 111 111 of Fig. 1. ,Fig. 4 is a fragmentary view, partly vin section, taken on the ,line IV of Re isa' op Plan, partlyfragmentary and partly. in detail, of

a number ofxthe rollers and rails used in con unct1on with the.firees capeu Fig. 6 is an enlarged fragmentary view showing a s de elevation of one of ithe. rails and end vlews of a number of the r'ollers. Fig. 7

is a fragmentary view, partly" in section, 7

taken on the line V V,of Fig. Fig. .8 1s a longitudinal section through one of the rollers, and Fig. ,9 is an end .view of one of the rollers.

The fire escape, or devicehas chute 1O which is tubular in form, and is preferably substantially square, or rectangular in cross section whereby two side walls ll and 112, a bottom .13, and a top wall Mareprovided.

When the fire escape is applied to a; building 5 as 14?, or other structure Of-II10I'6; th,a I1:OIl(- story in height the chute 10 ,is-constructed so as to be stationary therewith ,and is formed to provide integral, sections, as. .15, 16, 17, with a continuous passage there- .through, and each{ section .is ofalength to conform approximately to" the height (of each story 'of the building. ,As; shownin the drawings, the sections 1 5, 16,17 are disposed upon inclines in opposite .directions {relatively to each other to prevent too, precipitous: a descent for persons to .slide down the chute when the device is used in conjunction with achigh. structure. By providing readily be constructed entirely ofv cement, or other material which isfnon-inflammable and a non-conductor of heat, or may be constructed partly of metal and coated: with the chute of thefshape mentioned iit may cement, or th elilreso as :to be strictly fireproof as well as tendinggto deflectthe heat from. a burning structure,. instead of conducting the heat as is characteristic of fire escapes made of metal.

chute lOand adjacent to the'bottom thereof is a freely movable floorwhichtserves as a slideway .18 composed of a number .of rotatable members, or rollers 18? which arear- Interiorly of'each o-fthei-sectionsof the ranged adjacentito each other and disposed chute.

transversely of the sections of the chute. The rollers 18 may be of any suitable material, but each is preferably made of a round bar of metalwhich is covered with cement, as 19, in a manner so that each end of the bar is free of coating to serve asshort shafts 20 and 20. The shafts 20 and 20 of each of the rollers are rotatably disposed in spaced bearings provided in rails 21 and 22 one of which is arranged at each side of the bottom 13 of each of the sections of the The sections 1 of the chute '10 are niadebf dimensions" whereby the person sliding therethrough should be in a sitting posture, and'the rotation of the rollers will then serve-to carry the person in a downward direction as well as tending to prevent the person from stopping his descent by pressing the hands,ffor instance, against theside walls of thechute. When the chute is constructed of'a'number of sections, and

\ to check the rapidity of the descent of a person passing therethrough, I may dispense with the use of the rollers 18 at bends of the 'chute which form the junctures of the sections, "and instead flooring of cement, or

the like maybe used.

The chute 10' has an entrance 23 at its upper end, and an exit 24 at the lower end thereof. Where the chute has a plurality of sections each 'one'is of a length to extend from one story to the other of the building,

and at each story may be constructed in conjunction'w'ith the chute a platform, as 25, '26, 27, 27 Leading'into the sections 16 and 17"from"the platforms 26.and 27 are entrances *28' an'd 29, respectively, to permit persons todepart from various floors of a burning building, and conveniently enter the chute" In order that the persons entering the' sections of the chute at its various entrances will be compelled to pass therethrough'in'the same direction, I provide in the chutefat the'entrance of each of the sections except the top section a branch slideway, as 30and'31, each of which is arranged to converge with the main slideway of the chute, andithe floor of each of said branch slideways may be free of rollers, or composed of rollers similar to' the rollers 18 Upon each sectionof'the chute may be provided a stairway,' as 32, if desired, which may also be used asa means of escape from a building, and which is adapted to be constructed of cement, or other like material.

' In the foregoing"description, I have embodied the'preferred form of my invention,

but I do notwish to be understood as limiting myself thereto, as I' am aware that modifications may be made therein without departing from" theprinciple, or sacrificing any of the 'advantagesof this invention, therefore I reserve to myself the rightto make such changes as fairly fall within the scope of theappended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A device of the character described comprising a fire escape for a building having a plurality of stories, said fire escape including in combination a platform for each story of said building, a rigid integral covered chute including straight portions intermediate each platform, said portions being oppositely inclined one to another, an entrance chute comprising a slide leading from each platform into said integral chute, turns in said integral chute being formed adjacent to said entrance chutes, said entrance chutes being inclined at a greater inclination than the inclination of said turns, the mouth of said entrance chutes and said turns being substantially side by side.

2. A fire escape for a building having a plurality of stories including a platform for each story of said building, a rigid integral covered chute provided with an open stairway on the upper side thereof, said integral chute including oppositely inclined portions and an entrance chute for each platform leading into said integral chute beneath the respective platform from which said entrance chute leads, substantially as described.
