FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent N 0. 660,674. dated October 30, 1900. Application filed November 22, 1899. Serial No. 737,890. (No model) To all whom, it nuty concern:

Be it known that I, LOUIS WEBER, a subject of the Emperor of Austria-Hungary, residing at Uj-Verbasz, Austria-Hungary, have invented certain new and useful Improvements in Detachable WVindows for Saving Life in Case of Fire, of which the following is a full, clear, and exact description.

According to the present invention the window with the frame or sash forminga box-like whole is not fixed in the wall of the building, but may be removed easily therefrom and let down to the ground by suitable ropes or wires or the like, so that in case of fire persons living in the upper stories may release the window from the wall and gradually let the same down to the ground after having seated or otherwise secured themselves in the frame.

In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure l is a side elevation showing the Window-frame in position in the wall and the surrounding parts of the wall in section. Fig. 2 is a part front elevation of the window; Fig. 3, a plan of the window-frame with the adjacent wall parts in section, and Fig. at a perspective part elevation showing the position of the arms when the window is being lowered.

According to one form of carrying out my invention one or more pairs of arms 9 h and g h are pivot-ally attached at cl d at each side of the window-frame and provided with guiding-segments ff, which limit their movements around the pivot, so that when in operation the said arms will extend horizontally from the window-frame, Fig. 4E, and keep the same a certain distance up from the wall, so that the window when lowered will run clear of obstacles on the wall, such as facings and the sills of windows below. The said windowframe a, is supported at either side by means of cords or wires 0, fixed to a point e e on the said arms some little distance from the pivots d d of the same. If more than one pair of arms is employed at either side of the window, (two pairs are shown in the drawings,) the second pair g h is mounted below the first, and the cord is attached to one member g of the lower pair at e and taken up through an eye 6 on the corresponding member 9 of the upper pair. The two cords 0, one at either side of the frame, are then wound around a drum b, mounted on a shaft Z, mounted above the window, which is also provided with a counterpoise m, having cord b, which winds up as the window-cords unwind, and thus prevents a too-rapid movement of the said window downward. One membergg of each pair of arms is longer than the other it h and provided with a hooked or bent round end, Fig. 4, adapted when the window is lowered to engage a guide-groove j, extending down the front of the wall of the building, while the shorter member is provided with a foot It, which rests against the face of the wall and forms a supporting arm or strut for the said hook after the manner of a bracket-support. On lowering the window the hooked arm at either side of the same may be placed in the open upper end of the groove or railj. (See Fig. 4.)

The whole window-frame is supported on rolls t' t, mounted beneath the bottom or sill of the frame, and may be retained in position in the wall when not required to be lowered by any suitable means which may be easily disengaged. In case of fire the said fastening may be disengaged, the window will roll out of its seating in the wall, and the cords being stretched by the weight of the frame will pull the pairs of arms 9 h g it around into the horizontal position, the hooked arms 9 g will engage the guide-groove, and the somewhat-shorter arm h h of each pair will fall slightly below the hook of the longer arm and, resting with its foot against the face of the wall, will stay or support the whole frame. The person may getinto the windowframe and work himself gradually down to the ground, the counterpoise serving to prevent too-rapid descent.

I claim as my invention- 1. The combination of a Window having a window-frame detachably mounted in the wall, means for suspending said windowframe, and lateral lever-arms mounted at each side of the said frame and means for projecting them forward when the window is lowered, to retain the said frame the required distance from the front of the house substantially as described.

2. The combination of a window and frame detachably mounted in thewall, two pairs of arms pivotally mounted one above The other at each side of the said frame, cords at each side of the window and drums mounted above the window onto which said cords are Wound, the said cords having their ends attached to the longer hooked arms of each pair at suitable'distance from the pivot, and means at the front of the building to guide the said IO hooked arms, and a foot 70 to the shorter arms to serve as a strut substantially as described. In witnesswhereof I have hereunto set my hand in presence of two witnesses. I

V LOUIS WEBER.
