FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 323,092, dated July 28, 1885.

Application filed June 18, 1885. (X0 model.)

T0 to whom it may concern:

Be it known that I, LEOPOLD WERNER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, 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 willenable othersskilled in the art to which it appertains to make and use the same, reference being bad to. the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

In the drawings, in which similar reference letters indicate like parts in each of the figures, Figure 1 is a frontelevation of a window-casing and a side elevation of my improved swinging attachment arranged therein. Fig. 2 is a section of a window-casing, and showing the attachment swung out ofthe window and ready for use. Fig. 3 is a plan of the top of the swinging attachment, and Fig. 4 is a side view of the belt.

The invention relates to improvements in fire-escapes, and is designed to provide a safe and easily-operated device for lowering one or more persons from the windows or doors of a burning building; and it consists of a swing ing device removably attached to a window or door casing and provided with raising and lowering mechanism, substantially as illus trated in the drawings, and described and claimed hereinafter.

A in the figures of the drawings represents a window-casing, and B a swinging attachment composed of a post, b, an arm, I), and a brace, 1%.

To the window-casing-preferably inside of the window-sashes, as indicated in Fig. 2--are secured eyes or sockets (1 into which the ends of the post I) are inserted, said eyes being placed at such a distance apart that the post can be readily lifted therefrom. The arm I), which is composed of two parts, 2) b placed side by side, has journaled therebetween three pulleys, d d d", the central one, d, being of greater diameter than the two end pulleys, (1 d. The said post, arm, and brace, when the swinging frame is made of iron, are cast integrally; or, when made of wood, the said parts are securely bolted together.

The raising and lowering mechanism con-' sists of an endless chain, c, which passes over the small pulleys and under the large pulley d. A belt, f, having a ring, g, attached to one end, and a hook, h, to the other, is employed to lower persons from the wind ow. The hookend of the belt is passed through the ring, forming a loop, as indicated in Fig.2, which is passed over the head and drawn around the body of the person. The hook is caught in the chain, and the person lowered either by controlling the chain himself, or the descent may be retarded by controlling the chain from the ground.

The swinging frame can be permanently placed in position as in factories, or may be removed and placed in the room near the window, where it is within reach, and can be easily and quickly adjusted in the sockets.

It will be. noticed that the swinging frame is made only high enough to swing freely under the sashes when raised, as shown in Fig. 2.

Two or more persons may be lowered at the same time, and the belts hooked into the ascending part of the chain and passed up to the window.

The hook may be an ordinary hook or a snaphook, as desirable.

Having described and illustrated my inven tion, I desire to claim the following:

1. A fire-escape consisting of a post the ends of which are adapted to be inserted in sockets or eyes secured to a window-casing, saidpost being provided with an arm having three pulleys journaled therein, the central pulley being of larger diameter than the end pulleys, and an endless chain passing over the end pulleys and under the large central pulley, substantial] y as and for the purpose set forth.

2. The combination, with a window-casing having eyes or sockets secured thereto, of a fire-escape removably arranged in said sockets and turning pivotally therein, consisting of a post, I), provided with arms 1) b having three pulleys, d (1 d journaled therebetween, the central one of which, at, is of larger diameter than the end pulleys, d (1 an endless chain passing over the end pulleys and under the central large pulley, and a belt having a hook and ring at the ends thereof, all said parts being arranged and operating substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 10th day of 1 June, 1885.

LEOPOLD WERNER.
