The invention relates to improvements in fire escapes and an object of ,the invention is to provide a fire escape particularly adaptf ed for emergency use and which-will allow i an individual to escape through a window or other outlet froma building; land descend to the ground in safety and without requiring the help of others and which is designed so that one escaping can regulate the speed of descent by manipulatingy theV suspending rope in a proper manner. i

' A further' object is to construct'the device so that one using it can easily and qu`1ckly get properly intothe supporting sling and 1'- `without fear of entangleinent and further toV arrange the entire deyice: so that 1t can be, manufactured at relatively small cost. easily manipulatedV and easily' installed. A further object is to construct the device withan auxili'ary hook which canbe utilized When an exceptionally heavy person desires to descend and which has the sling ,thereof a-rranged to prevent the person sittinggin it falling backwards and which further 1s designed so that several runners and shngs can be placed on a single rope to permit severalV persons to escape from the same outlet.

With the above more important objects in:

View, the inventionconsists essentially in the arrangement andconstructlon of parts hereinafter more particularly described, referencebeing had to lthe accompanying drawings, in which Fig. l is a perspective Viewl of the device Fig. 2 is a perspective view of the runnen Fig. 3 is a perspective view of. a portion of the slng and showing the snap hook.

` In the drawings like characters of reference indicate corresponding parts in the several figures.

The rope 1 which is -employed will Vary in lengthdepending'on the distance which the window-or other :outlet where it is used is from the ground :and obviously the rope requires to be of sufficient Strength to carry its load with safety. i The upper end of the rope is provided with a loop or other means wherebythe `rope can be suspended from the window or outlet. Various means can obviously be employed for fastening the ingfhole'sk afland 5' are'rb provided; the faces i tension 12f pr'fwidingean open sided eye 13 uppei-rendof'the ropefl to the building struc-l Ar loop: show-n1 at 2 perintsM the rope to beIsHspendecl from an eye-book or the like (notherein shown).

TheV sling i istsnplink` 101 permanentlyl attached' to i the 1 lowen` end offthe runner and at the otherside with a;..snap=hook` orf other. well known deVi-oefen detaehahlysecuringit to theirunner.V The: bedy, of'tlie runner;` VVis -herein shown as:Providedv With;V ar h'ook. shaped lower exdirectlyfulnderwthe eye 5:.

When the one escaping; from the building throughV the window desires to use the de-- Vice,l the free end of the rope having been previously thrown out the window,V he will undo the Snap hook 11 to permit himself to take asomewhat sitting position in the sling upon the snapV hook being re-caught in the 7 eye 15. At such time, he will be sitting on the strap 8 .and the strap 9 will be passing across his back in a location below the arm pits. When he is ready to descend, he Will grab the rope with his both hands in a location somewhat slightly below the hooked extension of the runner and while holding the rope will step out through and Clear of the window. The friction developed between the rope and the runner will support him provided the down going end of the rope which he has grabbed in his hands is held in a tightly pulled down position. When he is ready to descend, he lets the rope slide slowly through his hands and he can very readily control the speed of descent by manipulating the rope With his hands.

I have found that two eyes such as those 4 and 5 receiving the rope will serve to permit a person of average weight to descend in safety and control their descent readily. If, however, an exeeptionally heavy person is to descend, it would be desirable for him to pass the down going end of the rope through the eye 13 before descending and this can be very easily and quickly done at the time he is getting into the sling as at such time the Snap hook is undone. With the rope Operating through the three eyes, considerable more friction can be developed and accordingly a much heavier person can descend with safety.

While I have shown one runner and a sling mounted on the rope, several of these could be placed thereon and such would permit several persons to descend by the same rope.

What I claim as my invention is 1. A fire escape comprising a suspending rope, a runner having a pair of upper and lower eyes through which the free end of the rope is threaded and an underlying hooked extension, said hooked extension being provided with a pair of eyes, a sling em'- bodying a seat strap and a back strap permanently fastened together, a link connecting one side of the sling to one of the eyes of the hooked extension and a snap hook connecting the other side of the sling to the other of the eyes of the hooked extension.

2. A runner for a fire escape rope having the body part thereof in the form of a figure 8 and provided at the under side With a. hooked extension and the hooked extension fitted on the under side thereof with a pair of eyes.
