Annemarie FIRE-ESCAPE.

. Specification of Letters Patent.

Patented July 17, rear.

Application filed. May 29, 1916. Serial No. 100,640.

To all whom it may concern:

Be it known that 1, Mrs. HULDA E. As'rA- RITA, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Automatic Fire Escapes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an automatic fire escape.

An object of the invention resides in the provision of an improved fire escape which may be permanently located adjacent to a window so that portions thereof may be swung out of the window when it is necessary to use the device.

A further object of the invention resides in the provision of a novel carrier for the persons.

With these and other objects in view, such as will appear as my description progresses,

my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.

In the drawing:

Figure 1 is a side elevation of a device constructed in accordance with my invention showing the pulley supporting arms extended beyond the window sill in full lines and in their retracted positions in dotted lines;

Fig. 2 is a plan view;

Fig. 3 is a detail of the shock absorber;

Fig. 4L is a perspective view of one of the carriers, and

Fig. 5 is a sectional view of the same showing the body engaging loop.

The embodiment of my invention illustrated in the drawing includes a frame 1 which is adapted to be secured in a room adjacent to the window sill 2 and on which a pair of arms 3 is pivoted. Pivoted, at 4, to these arms 3 are arms 5 on the ends of which pulleys 6 are mounted. These arms 3 and 5 are adapted to swing into the positions disclosed in dotted lines in Fig. 1 when the device is not in use and also into the positions shown in full lines in this figure when the device is in use so that the arms 55 will rest upon the window sill 2. A drum &7 is mounted on the frame 1 and is provided with sprockets 8 over which chains 9 pass,

which chains pass over additional sprockets 10 and retard the movement of the drum 7. Angularly disposed pulleys 11 are mounted upon this frame 1 adjacent to the window sill. A flexible cable 12 passes about the drum 7 over the pulleys 11 through guides 13 011 the arms 5 and over the pulleys 6, from which pulleys the ends depend.

Secured to each end of this cable is a carrier which includes a bar 1a from the ends of which ropes 15 depend. A foot piece 16 is secured to the ends of these ropes and a seat 17 is likewise secured to the ropes in spaced relation to the foot piece. Eyes 18 are carried by the ropes above the seat 17 and a fastening member 19 passes through the foot piece 16 and thence upwardly through the seat 17 and through one of the eyes 18, it thence passes to and through the other eye 18 and thence back through the first eye and through the second eye again and is then extended downwardly through the seat 17 and the foot piece 16. Thus a loop 19 is formed between the eyes 18. It is obviouswith this carrier that a number of persons may be carried to the ground by resting upon the seat and foot piece. Should it be desired to secure the person within the carrier it will only be necessary to expand the loop 19 at which time the foot piece 16 will be drawn toward the seat 17. The loop may then be placed around the body of the person who seats himself upon the seat 17 and rests his feet upon the foot piece 16.

Any pressure exerted against the foot piece will tighten the loop about the body of the person and thus securely fasten him in position.

Secured to the end of each of the arms 5 is a plate 20 on which a second plate 21 is mounted which is held in spaced relation to the plate 20 by springs 22. These plates 20 and 21 are provided with central openings through which the cable 12 passes. The presence of the springs between these plates will prevent the sudden stopping of the carriers so that their movement toward the pulleys 6 will be arrested gradually.

It will beobvious that the carriers will alternately move to and away from the ground and that the particular arrangement of the drum and sprockets will retard the movement to such an extent that the descent may be made at a convenient rate of speed.

While I have illustrated and described a rel ing adapted to be swung to an inoperative position interiorly of the window sill and also swing to an operative position with said other arms resting upon said sill, a drum on said frame, pulleys on said other arms, an'gularly disposed pulleys mounted on the pivotal connection between said frame 20 and the first named arms, a cable passing over said frame and said pulleys, and earriers secured to the ends of sald cable.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
