GEORGE KENYON OF SPRINGFIELD, ILLINOIS.
IMPROVEMENT IN FIRE-ESCAPES.
Specication forming part of Letters Patent No. 200,200, dated February 12, 1878; application filed November 6, 1877.
I To all whom 'it may concern: Y
Be it known that I, GEORGE KEnYoN, of Springfield, in the county of Sangamon and State of Illinois, have invented a new and Improved Fire-Escape, of which the following is a specification:
In the accompanying drawing, Figure 1 represents a vertical longitudinal section of my improved fire-escape on line x a', Fig. 2; Fig. 2, a side elevation; and Fig. 3, a vertical transverse section of the same on line x x, Fig. 1.
` suitable metal frame, to a central revolving shaft, B, of which a drum, O, is applied. The drum O is keyed to the shaft, and the latter made with a square outer head, to admit the winding up of a wire cable, D, of sufficient strength to carry five himdred pounds. The wire cable is attached to the shaft at one end, and applied by a spring snaphook, a, at the opposite end, to a staple above or near the window, or to any other Xed point of support. The drum O is cast with a llange, O', equal to the outer diameter of the drum, around which a steel friction-band, E, is
placed, and tightly applied by being attached by end staples or links b to a lever-handle, F, at both sides of the fulcrum of the same, on the Xed handle F', that is cast in one piece with frame A. The swinging handle is connected to the fixed handle by a strong band-spring, d, that keeps the brake device stretched for slow descent. By pressing' the handles together the descending motion may be retarded or stopped. When arriving at the ground the device may be pulled up again,
and the wire rope rewound on the drum by means of a hand-crank or key applied to the square end of shaft B, to be used againv for descending by the next person, forming a reliable, strong, and compact lire-escape for buildings of all kinds.
l am aware that it is not new to use a reel for the suspensioncord on which the casing slides, and straps forY attaching the casing to the person, or a friction-brake that encircles a pulley on the reel-shaft, so that the descent of a person may be regulated.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A hand device for operating the brake-band of a fire-escape pulley or drum, consisting of the fixed handle F', spring d, and movable handle F, the latter receiving both rings of brake-band, and being fulcrumed on a projection of Xed handle, as shown and described.
GEORGE KENYON.
