FIRE-ESCAPE arrncnmnnn Application filed April 2, 1912. Serial No. esaooo.

To all whom it may concern I Be it known that I, MARGUERITE 508m, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fire-Escape Attachments, of which the following .18 a specification, reference being had therein to the accompanying drawing.

This invention relates to fire escapes and has for its object the production of an efficient fire escape of the ladder type which maybe conveniently adjusted to a house, or other building within a minimum amount of time.

Another object of this invention is the production of an efficient support for carrying the escape basket which is adapted to hang from the upper end of the ladder.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed. a 1

In the drawings :-Figure 1 is a front elevation of the device in an operative position. Fig. 2 is a side elevation of the device upper ends the usual hooks 2, for

illustrated in Fig. 1. Fig. 3 is a top plan 4 is a detail perspective of the carrier basket. Fig.5 is a plan view of the carrier basket showing the same in a collapsed condition. Fig. 6 is a perspective view of the carrier basket in its folded condition. Fig. 7 is a detail perspective of the upper end of the ladder, showing the manner of the bracinghook thereto.

By referring to the drawings, it will be Seen that the mechanism comprising the fire escape consists in a ladder 1, having at its attaching the Window sill and the top or sides of a building. This ladder is provided near its upper end with a hinged carrier basket support 3. which support is braced by means of an angle web portion 4; The web portion 4 1S preferably formed integral with the carrier basket supporting arm 3, and is hinged to the side of the ladder by means of hlnges 5. This carrier basket support is adapted to be folded in back of the ladder or in the position as shown in dotted lines in Fig. 1 so that the ladder may be conveniently carried from place to place without the carrier basket support being inthe way of foreign Specincation of Letters Patent engaging "tra'ted in Fig. 5. Rein formed upon the outer end of the sides 16 -21, which eyes are engaged by means of the Patented Jan. 276, 11915.

objects. This carrier basket support is provided at its outer end with a bracing arm or rod 6 which arm or rod is provided with a hooked end 7, and this arm when the carrier basket supporting arm 3 is in its extended position passes in back of the carrier basket support and in backof the ladder so as to have the hooked'ends 7 engage an eye 8 formed upon the opposite side member of the ladder. In this manner, the bracing arm or rod 6 will constitute a very efficient brace by passing in back of the carrier basket support 3. I By carefully considering Fig. 1, it will be seen that the brace or angle web portion 4 extends for approximately half the width of the basket supporting arm 3 and extends at an angle so as to form an eiiicient brace at the point from which the carrier basket is suspended. I

A'supporting hook 9 is carried interme diate the ends of the carrier basket support 3, and is adapted to engage the window sill for holding the arm in engagement there with, and this hook is so placed as to form an etficient' brace for the support at the point from which the carrier basket is suspended. Y Y A pulley 10 is journaled' upon the carrier basket support intermediate its end and preferably directly below the hook 9,"and

a second guide pulley 11 isjournaled near the inner end of the basket support 3. A drum 12 isassociated with the ladder 1, and upon this drum 12 is Wound a carrier basket supporting cable 13, which cable passes over the pulleys 10 and 11 and engages thesupporting ring 14 0f the carrier basket. Diverging cables 15 are connected to the'ring 1 1 and these the collapsible sides 16 of the carrier basket. This carrier basket is collapsible so that the same may be folded as illustrated in Fig. 6. The side sections 16; of the carrier basket are hingedto the bottom 17 by means of 100 lacing cables 18. These lacing cables are formed of metallic strands or may be otherwise formed and the carrierbasket may be formed of any desired metal. The bottom 17 is provided with a orcing cleats 20 are and upon these cleats are formed the eyes hooks 22.

cables 15 engage .9

adding 19 as illus- '10.

' The sides 16 ofthfecafriei basketjwlien'ip easily carried chain 23 is ad a cured to the $1 basket, and is provided with a hook 25 for bang basket supporting ladder and links of the chain for en a in one of the g g g in their correct set-up holding the sections position. 4 I 0 From the foregoing descriptlon, 1t Wlll be obvious that a very eflicient and durable device has been produced which may beset up quickly and may be easlly transported from place to place, as for mstance the device may be easily carrled upon a truck as is the custom with the ordinary ladders now in use. The ladder .1 may be formed of the ordinary construction, and is rovided with the-usual side cleats 26.

en the carrier basket support is folded upon the ladder, the bracing arm 6 may thereby be out of the way of foreign objects as is illustrated in.Fig 1 of'the drawings 1n dotted lines.

Of course, it should be understood that the hinged arm 6 is secured to the carrier member by means of a universal joint to allow the hook to swing downwardly when the carrier basket is folded upon the ladder.;

Of course, it should be understood that this invention may be modified in its detail mechanical construction without departing from the spirit of the invention.

What is claimed is s 1. A fire escape of the class described, comprising a ladder, a carrier-basket-sup-' porting arm hingedly secured to one side of said ladder, said carrier-basket-supporting arm beingof the same thickness as said having its inner end resting against the side of said ladder, whereby outward swinging of said carrier-basket-supporting arm will be limited, 'and a bracing arm hingedly secured to the outer end of said carr'ier-basket-supporting arm for firmly holding said carrier-basket-supporting arm in an extended position and preventing the backward folding of said carrier-basket-supporting arm.
