ELEANORE EDER, OF ST. LOUIS, MISSOURI.

FIRE-ESCAPE LADDER.

SPECIFICATION forming part of Letters Patent No. 444,607, dated January 13, 1891.

Application filed November 3, 1890. Serial No. 370,182. (No model.)

To all whoa@ it may concer/L.-

Be it known that I, ELEANORE EDEE, of the city of St. Louis and State of Missouri, a subject of the Emperor of Germany,have invented certain new and useful Improvements in Fire- Escape Ladders, of which the following isa full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Myinvention relates to improvements in reescape ladders; and itconsists in the novel arrangement and combination of parts, as will be more fully hereinafter described, and designated in the claims.

In the drawings, Figure 1 is a perspective View of my invention as applied to abuilding. Fig. 2 is a vertical longitudinal section of a modification of the same. Fig. 3 is a horizontal cross-section taken on the line fr 00 of Fig. 2. Fig. 4 is a top plan View of a further niodilication of my invention. Fig. 5 is a top plan View of the same when placed in an open position.

Referring to the drawings, l represents a wall of an ordinary building, to which my invention or fire escape ladder ll is permanently attached by means of cleats 2, which are adapted to pass around upright pieces 3 3, and are then secured to the wall or to the Window-frame, as shown in Fig. 1,in any suitable 'and substantial manner. The lower end of the ladder is likewise suitably attached to the wall.

S and 44. represent the four upright pieces of said ladder, which are so connected by a series of rounds 5 that a shaft is formed between said upright pieces and said rounds. Said shaft is constructed of sufiicient dimensions for persons to move freely upwardly and downwardly therein, and if they should perchance be overcome by the excitement and terror of the conlagration and fall, they Will fall against the sides of the shaft, and thus be rescued from their probable perilous descent. At each story a sufficient space is left between three exterior sides of the shaft and at the same time others may descend on the insides thereof.

In Figni a modification is shown,\vhereIcon struct my ladder by using four ordinary ladders and connecting them so as to form a shaft by means of bands 7 passing around the adjacent upright pieces of said ladder.

In Fig. 2 a further modification is shown, where I use two ladders, one of which is permanently attached to the wall and the other attached to the one that is permanently attached by means of cross-pieces 8. To these cross-pieces and on each side of the shaft formed by connecting said ladders together' I may attach water-pipes 9, which may be utilized for ordinary purposes, and also for a sliding pole in rapid descent.

One of the ladders may be attached to the wall and the others opened out when not in use against the wall, as shown in Fig. 5.

Having f ullydescribed myinvention, WhatI claim is- 1. A permanent fire-escape ladder consist ing of a shaft 6, the front and back sides provided With rounds and the lateral sides thereof provided with sliding poles, as and for the purposes specified.

2. A permanent [irc-escape ladder 'having a shaft provided with a combined tubular sliding pole and water-pipe, substantially as set forth.

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

ELEANORE EDER. Witnesses:
