FIRE-ESCAPE.

- SPECIFICATION forming part of Letters Patent No. 294,848, dated March 11, 1884.

Application filed May 8, ices. (No model.)

To aZZ whom it may concernn Be it known that I, ROBERT ALFRED BUsH, a subject of the Queen of Great Britain, residing at Brockville, in the county of Leeds and Province of Ontario, Dominion'of Canada, have invented a new and useful Fire-Escape, of which the following isa specification, reference being had to the accompanying draw lugs.

This invention relates to that class of fireescapes in which a flexible ladder forms the means of exit or escape; and it consists in certain improvements in the construction and arrangement of such fire-escapes, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figurel isder sides, at their inner ends, which clampthe sill and brace and hold the device securely in position. The rails A A are provided at their outer edges with flanges O 0, having slots D D, which form hand-holes to assist in the descent when the escape is to be used. The

.upper edges of the flanges C have recesses E,

forming bearings for the trunnions F F of a reel, G. The front ends of the rails A A have perforated lugs H H, to which the flexible es cape-ladder I is attached. The sides of the said ladder are preferably constructed of wire rope, and the rungs of iron bars or tubing. The lower ends of the sides of the ladder are secured to staples J J, which are attached 'loosely to the body of the reel G, so that the weight of the latter shall be sufficient to deder. The ladder is to be wound upon the reel G, and the latter supported by its trunnions F in the bearings E, above mentioned. When in this position, the escape is to be covered by a detachable cabinet or easing, K.

The operation of my invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. In case of fire, orwhen it is desired to use the-escape, the casing is to be mistakes are not liable to occur, as is the casein fire-escapes where intricate mechanism has to be employed to unroll the escape-ladders.

Instead of securing the rails A to the sill of the window, they might be secured to the floor, or in any suitableconvenient position.

I claim as my invention and desire to secure by Letters Patent of the United States- 1. In a fire-escape, the hereindescribed base-rails, adapted to be secured toa windowsill, and having hooks at their rear ends clamping the edge of the sill, side flanges provided with hand-holes, and perforated lugs at their front ends, in combination with a fleXible escape-ladder secured to the said lugs, as set forth.

2. .The combination, with a flexible fire-escape ladder, of a reel secured to the lower ends of the sides of said ladder by means of staples loosely connected to the said reel, so

that the said reel shall become detached byits .own weight when the ladder is unrolled, substantially as set forth.

3. As an improvement in fire-escapes, the combination of a pair of rails adapted to be secured to a window-sill. and having side flanges provided with hand-holes, and having recesses in their upper edges, forming bearings for a reel, a flexible ladder attached to the front ends of said rails, and a reel at" tached to the lower ends of the sides of the said ladder by means of staples detachable from the said reel by the weight of the latter, the ladder being wound, from the bottom up, upon the reel, and the latter supported by its trunnions in the bearings in the upper edges of the flanges of the rails, substantially as set forth.

1 In testimony that I claim the foregoing as my own I have-hereto affixed my signature in presence of two witnesses.

ROBERT ALFRED BUSH.
