FIREBESCAPE.

SPECIFICATION forming part of Letters Patent No. 312,909, dated February 24, 1885.

(No model.)

the following is a full, clear, and exact de-` scription, reference being had to the annexed drawings, making part of this specification, in which- Figure lisa front elevation ofthe improved fire-escape in position, the buildingfront being shown in broken lines; Fig. 2, a front elevation, upon an enlarged scale, ofthe escape; Fig. 3, a side elevation ofthe escape, the build ing-front being shown in vertical section; and Fig. 4, a horizontal section, upon an enlarged scale, upon the line 4 4 of Fig. 3.

The same letters of reference denote the same parts.

The present invention is an improvement in that class ofre-escapes wherein a ladder ispermanently attachedr to the building.

'lho improvement relates tothe means by which the ladder is attached to and adjusted upon the building.

A represents the ladder.

B represents a toothed rail or rack,attached by means of brackets, such as b, to the build ing C at or toward its top. The rail may eX- tend along the front c, as well as along the sides ofthe building.

D represents another toothed rail or rack, which is attached to and extends along the i'ront or front and sides ofthe building` lower down upon the building than the lirst-named rail.

The ladder is hung upon the two rails B D as follows:

E represents a hanger attached to the ladder and provided with a pinion, F. The pinion has daring anges ff, and it is attached to a shaft, j, which passes through the hanger, and in front of the hanger is provided with a bevellgear, G.

Opposite the lower rack, D, a shaft, Il, :is journaled in the ladder, the shaft extending at right angles to the ladder, and provided in front of the ladder with the gear I and the bevel-gear J. and in rear ofthe ladder with the pinion K. The pinion engages with the lower rack, D.

L represents an upright shaft journaled in the ladder at l Z, and provided with the bevelpinions Z Z2, which engage, respectively, with the bevel-gears G J.

M represents a crank-shaft journaled inthe ladder at m and provided with the pinion m', which engages with the gear l.

The ladder is also furnished with the grooved pulleys N N, which are adapted to roll upon a rail, O, which is attached to the building in front of the lower rack, D.

Ou rotating the crank M motion is imparted to the upright shaft L, and through it to the pinions F K, and the ladder in consequence is moved laterally along the building front or sides and to the right or left, according to the direction in which the crank-shaft M is rotated.

rPhe sides a c of the ladder are preferably made tubular, to furnish means for conducting streams of water upward onto the building. The upper end of the ladder is extended at A A', Figs. 1. 3, to enable the water to be thrown onto the roof of the building.

I claiml. The combination of the rails B and D, the ladder A, the hanger E. the shaft H, and the wheels F K, adapted to be applied to a building, substantially as described.

2. The combination, as described, of the racks B D, the ladder A. the hanger E, the shaft H, the wheels F K, the gears G I J m', the shafts L M, the rail O, and pulleys N N, adapted to be applied to a building, substantially as described.
