FIRE-ESCAPE.

srncrrxonrxon formingpart of Letters Patent No. 715,560, dated December 9, 1902.

Application filed March 27, 1902 Serial No. 100,235. (lilo model.)

To all whom it ma/y concern.

Be it known that I, PH LIP HENRY DED- RICK, a citizen of the United States, and a resident of Grandview-on-Hudso'n, inthe county of Rockland and State of New York, have invented a new and Improved Fire-Escape, of which the following is a full, clear, and exact description.

This invention relates to improvements in fire-escapes; and the object is to provide a device of this character comprising aseries of platforms so arranged that a person or persons may slide from one platform to another, and thus gradually descend without injury by the fire-escape from any floor of a building.

I will describe a fire-escape embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying yielding walls in saidshaft, inclined platdrawings, forming apart of this'specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation showing a fire-escape embodying myinvention. Fig. 2 is a section on the line 2 2 of Fig. 1, and Fig. 3 isa sectional detail showing a portion of one of the platforms and its support.

Referring to the drawings, 5 designates a shaft or well that may-be arranged in a building or on the outer side thereof and communicatjng with .the rooms of the various floors through doorways 6. Arranged alternately at opposite sides of the shaft are platforms 7 8. These platforms may be made of any suitable material, and they are placed" at an incline, the platforms at oneside being ata reverse incline to the platforms at the other side, as clearly shown in the drawings. Oonnected to the walls of the shaft are metal frames 9, which are preferably of angle-iron, and to the upper'portions of these frames the platforms are hinged, as indicated at 10, and placed below the lower ends of the platforms and the lower ends of the side members of the frames are cushions or springs 11.

In the operation a person by stepping onto one of the platforms will slide therefrom onto .the platform extended from the opposite wall preferably made yielding. I have shown said opposite side walls at. 12 13, between which and the main fixed walls of the shaftare springs 14:. These yielding walls will prevent possible danger to persons striking against them. 1

Having thus described my invention, 1'

claim as new and desire to secure by Letters Patent- 1. A fire-escape comprising a shaft, spring forms extended from said yielding walls to- Ward the center of the shaft, the platforms of one side alternating with the platforms at the opposite side, hinges supporting the upper ends of the platforms, and springs having connection with the platforms, substantially as specified.

2. A fire-escapecomprisiug a shaft, frames arranged at opposite inclines in said shaft, platforms having hinge connection with the .upper portions of the frames, and spring connections between the lower ends of the platforms and the frames, and holding the lower ends of the platforms normally above the frames, substantially as'specified.

' In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses:

EDGAR T. SMITH, E. J. FAY.
