FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 285,296, dated September 18, 1883.

Application led January 27, 18H3. (No model.)

To all whom/it may concern Beit known that I, JOHN MOEEET, a citizen ofthe United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in 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 nre-escapes; and it consists in the construction and arrangement of parts, as hereinafter more fully described and claimed.

In the annexed drawings, illustrating the invention, Figure l represents the interior of a room with my improved fire-escape arranged at one side of a window. Fig. 2 represents the nre-escape turned so as to project through the window and with the ladder let down ready for use. Fig. 3 shows an end view and a longitudinal section of one of the tubular ladder-rounds.

Like letters are used to indicate like parts in the several views.

Thefire-escape consists, essentially, of abent or curved arm, A, carrying a spool, windlass, or drum, B,'to which is attached one end of a rope or chain ladder, C. The arm A is supported upon a standard, D, that may be fixed to the door within a room at one side of awin dow, said arm being attached to the standard `in such a manner as to be easily rotated so as be raised or lowered to correspond with the height of the window-sill. When the arm A is turned so as to project through the open window, it may rest upon the window-sill or upon a bracket, b, attached to the windowframe for that purpose.

The ladder C lis attached at one end to the spool or windlass B, and consists of a number of tubular rounds, c 0,'that are connected by ropes or chains d d, passed through the rounds so as to cross or pass each other within said tubular rounds, as shown in Fig. 2. rIhe tubes c c, composing the rounds of the ladder, are spread or flared at the ends, as shown in Fig.. 3, to form grooves or indentations e, that receive the ropes d, and thus prevent the rounds from cutting the rope or turning thereon, no other fastening being needed.

This fire-escape is exceedingly4 simple in construction and in operation, there being no complicated parts to become disarranged, and it being only necessary to turn the arm A so that it will project through the open window, when the weight of the ladder G will cause the windlass or druinB to revolve, so as to let the ladder down ready for use. As the arm A, carrying the spool or windlass B, is bent at one end, it will project through the window at a right angle with the outer side of the wall, and persons can readily ascend or descend the ladder withsafety.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a iireescape, the combination ofthe standard D, rotating arm A, carrying spool or drum B, and the rope ladder C, attached to said drum, substantially as shown and described. j

2. In a fire-escape, the combination, with the standard D and adjustable rotating arm A, attached to some iixed or movable article of furniture, as E, of the drum B and rope ladder C, substantially as shown and described.

3. In a fire-escape, the rope ladder G, composed ofthe tubular rounds e c, having flared ends provided with grooves e c, and the ropes cl d, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

Jenn MOEEET.
