Specification of Letters Patent.

Patented July 21, 1914.

Application filed February 12, 1912. Serial No. 677,223.

To all whom it may concern:

Be it known that 1, MAX Bosnian, a citizen of the United States, and a resident 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 specification.

This invention relates to a class of devices or fire escapes adapted to be used upon a building for permitting the occupants to safely depart therefrom in emergency.

My invention has for its object primarily to provide a form of fire escape designed to be constructed upon the exterior of a building, or other structure, and employed especially to permit a large number of persons who may occupy the building to quickly and safely depart therefrom when imperiled by fire, or other danger. These advantages are attained mainly by providing a fire escape in which a chute composed of a number of communicating sections are employed in successive arrangement upon a building, and which are inclined downwardly in opposite directions from story to story of the buildiinother object of the invention is to provide a form of chute having an undulating main chute or bottom whereby the speed of the person sliding theredown will be partially checked so as to obviate injury from impact at their exit from the chute.

Still another object of the invention is to provide an entrance to each section of the chute at each story of the building in order to permit persons in various parts thereof to depart simultaneously; and a further object of the invention is to provide at each entrance a branch raceway which converges with the main raceway so that persons passing into the chute from the lower stories of the building will not obstruct the'downward passage of the persons in the chute.

A still further object of the invention is to provide a form of chute upon the sections of which may be constructed a stairway adapted to serve as a means of escape from the building as well as permitting firemen or others to gain convenient access to the upper parts thereof in emergency.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawing, which form a part of this specification, and will then be pointed out in the claim at the end of the description.

In the drawing, Figure 1 is a front elevation of a building with one form of fire escape embodying my invention applied thereto, part of said fire escape being broken away. Fig. 2 illustrates a rear end view, partly broken away, of the fire escape, and Fig. 3 is a top plan of the fire escape.

The device or fire escape 10 has a chute 11 which may be composed of a plurality of communicating sections 12, 13, 14 in accordance with the number of stories of the building, as 15, upon which it is applied. All of the sections of the chute 11 are preferably alike in formation, each being substantially rectangular in shape, and may be constructed so as to be suitably supported in staggered arrangement in opposite directions on a downwardly incline from one story to the other story of the building, in order to provide a curve or bend at each meeting point of the sections so as to avoid too precipitous a passage through the chute especially when the fire escape is applied to high buildings, or other structures.

As a means to partially check the speed of persons when sliding through the, sections of the chute 11 so as to obviate injury from impact when departing from the exit, as 16, at the base of the chute, each section thereof is provided with a bottom in the form of irregular curves, or wide corrugations, as illustrated, whereby an undulating main raceway, as 17, is provided. By providing the irregular curved bottom or undulating raceway 17 as well as the curved or rounded junctures of the sections of said raceway it is evident that a person may slide down the chute from a great height with comparatively little or no danger of being injured.

Upon the building, as shown in the drawing, may be provided a number of platforms, as 18, 19, 20, one of which is suitablv supported so as to be in proximity to the windows, or other means of exit, of each floor thereof. Upon the top platform is an inclosure 21 which is preferablv spaced from the wall of the building, and said inclosure has a doorway 22 leading to the main raceway 17. Upon each of the platforms 18 and 19 is a similar inclosure 23 and 2 1 which are likewise spaced from the inclosures 23 and 24L and communicating with the main raceway 17 by converging therewith as shown at 27, at thetop of I each section of the chute is a branch racej way-28 and 29 adapted to permit persons to enter into the main chute after passing into the inclosures 23 and 24: from the lower platforms and escaping by way of the main raceway at the same time as the persons from the upper part of the building are sliding down the main raceway.

' Upon each section of the chute 11 is a stairway 31, 32 which are adapted to serve as means for permitting the occupants of the building to escape therefrom in'emergi ncmandsaid stairways may also be used by firemen or others in gaining convenient access .to the upper parts of the building as occasion requires.

' I t e ressing s ipl I h e bodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacri- Y A fire escape comprising a series of covered chutes, said chutes being arranged in series to-form alternately and oppositely inclined flights with reference to a vertical line; the chute of the higher flight joining the chute of the next lower flight .by a curved bottom surface to form a'continuous slide from top to bottom of the fire escape; and anentrance to each chute,said entrance leading to the chute of the next lower flight and the mouth of said entrance being wholly above the termination of the chute of the next higher flight thereby preventing flames and smoke from being drawn into the fire escape. I

This specification signed and witnessed this 9th day of February, A, D. 1912.
